Description

SH I E DED ELECTRI CAL CONNECTOR This invention is related to a shielded electrical connector , and , in particular, it relates to an electrical connector in which the housing isolates the electrical contacts to prevent cross talk . Electrical connectors with a large number of contacts are often used in computers , particularly large computers which produce a large number of transmission signals . One example of a known electrical connector is described with reference to Figure 9. This connector comprises first connector 1 which contains multiple plug contacts 2 secured in rows in a receptacle dielectric housing 3 , and a second connector 5 which has multiple receptacle contacts 8 secured in rows within plug housing 6 corresponding to the array of plug contacts 2 in the first connector 1 . When plug housing 6 is mated with receptacle housing 3 , the plug contacts 2 electrically connect with the corresponding receptacle contacts 8 thereby making an electrical connection therebetween . The other end of the receptacle contacts 8 protrude as exposed terminal sections externally from the rear surface of plug housing 6 and are bent downward as shown in Figure 9 thereby comprising multiple rows of terminal sections 8a which are held in multiple rows by dielectric retaining plate 7.
The above type of electrical connector permits a high number of transmission signals to be processed using a small and light connector. However , because the terminal sections of the receptacle contacts 8 in the second connector 5 are exposed and further because the spacing between the receptacle contacts 8 has been reduced as a result of the requirement to increase the number of transmission signals , cross talk is generated between the adjoining contacts thereby resulting in noise faults occurring . The chances of cross talk being generated and thus the risk of noise faults increase with the higher transmission signal speeds made possible by the larger capacity and better performance of computers . According to the present invention , a shielded electrical connector prevents the generation of cross talk and eliminates the risk of noise faults occurring .
The shielded electrical connector according to the present invention comprises a housing formed from metal housing sections coated with insulation material. Each housing section includes contact-retaining channels in which contact sections of electrical contacts are disposed and isolated from one another thereby forming a row of electrical contacts . The housing sections with the electrical contacts in place in the contact-retaining channels are assembled in stacked relationship forming the shielded electrical connector. The housing sections of the shielded electrical connector are electrically connected together for electrical connection to ground when the shielded electrical connector is mounted onto a printed circuit board . Selected electrical contacts are electrically connected to their respective housing sections thereby connecting these electrical contacts to ground.
An electrical connector wherein each electrical contact is respectively retained and isolated in the retaining channels of metal housing sections coated with insulating material prevents the occurrence of noise by preventing cross talk between adjacent electrical contacts.
A preferred embodiment according to this invention is described by way of example with reference to the accompanying drawings .

FIGURE 4 is a view similar to Figure 3 showing the electrical contacts fitted in the contact-receiving channels of the housing section . FIGURE 5 is a part cross-sectional view showing the - projections of the housing sections in electrical engagement.

FI GURE 8 is a view taken along line VI I I-VI I I of Figure 6. FIGURE 9 is a perspective exploded view showing a prior art electrical connector .
Figures 1 and 2 show the housing H of the shielded electrical connector SC according to this invention , which includes housing sections 10-60 and the cover section 80. Each housing section 10-60 is formed with a plurality of vertical walls 1 1-61 which are respectively extended to the front and back on base plates 13-63 , and a plurality of contact-retaining channels 12-62 which are arranged laterally and separated by the walls 21 -61 . These contact-retaining channels 12-62 merge into terminal-retaining channels 14-64. These contact-retaining channels 12-62 and the terminal-retaining channels 14-64 respectively retain electrical contacts therein with Figure 2 showing contact 17 retained in the contact-retaining and terminal-retaining channels 12,14 of bottom housing section 10. Contacts similar to contacts 17 are retained in contact-retaining and terminal-retaining channels 22-62 ,24-64 of housing sections 20-60 but are not shown . The contact 17 comprises a receptacle section 17a at the front portion thereof, which is to be engaged and electrically connected with a mating plug terminal through the front surface of housing section 10 , leaf spring members 17b at the center portion thereof, and a terminal section 17c at the rear portion thereof. The receptacle section 17a and leaf spring members 17b are received in the contact-retaining channel 12 , and the terminal section 17c is then bent along the terminal-retaining channel 14. The outer end of terminal section 17c projects downward from the bottom surface of housing section 10. The housing sections 10-60 having the above-mentioned structure are stacked successively , as shown in Figure 2 so that the contact-retaining channels 12-62 are arranged vertically and horizontally in rows. On the other hand , the terminal-retaining channels 14-64 are curved and the outer ends thereof are open to the bottom surface of the housing H . Moreover , these outer ends of the terminal-retaining channels 14-64 are arranged in horizontal and lateral rows in housing H in such a manner that these outer ends remain open so that the terminal sections of the contacts extend downwardly from the botton surface of housing H .
The cover section 80 is an upper plate 83 covering the contact-retaining channels 62 of the uppermost housing section 60 and the terminal-retaining channels 64. Cover section 80 also includes a pair of side walls 82, as shown in Figure 1 , which cover the sides of the housing sections 10-60 when assembled, and a pair of flange portions 81 . The cover section 80 is fitted over the assembled housing sections 10-60, which are successively assembled with electrical contacts in their respective channels as explained above, and the flange portions 81 of the cover section 80 and the flange portions 15 of the lowermost housing section 10 are then joined with a bolt and nut or other suitable securing means , 'thus completing the housing assembly of the shielded electrical connector. The housing sections 10-60 and the cover section 80 can be formed respectively by die-casting from a suitable conductive material , for example, zinc , and then coating all surfaces of the sections with an insulation material , for example , polymide. Therefore, the contacts 17 are insulated from the housing sections by an insulation coating when retained in the respective retaining channels 12-62, 14-64, and cross talk between the contacts 17 as prevented by the die-cast conductive metal .
Each housing section has the terminal-retaining channels , the length of which is different from those of the other housing sections . Thus , different contacts having terminal sections corresponding to the terminal-retaining channels must be made. Moreover, when the electrical contacts are retained by the respective retaining channels , the receptacle sections thereof having the same configuration are arranged in lateral and vertical rows . Further , each terminal section of the contacts projects from the bottom surface of the housing H while also arranged in horizontal and lateral rows .
Figure 3 is a perspective view of the lowermost housing section 10 , and Figure 4 shows contacts 17 retained in channels 12 and extending along channels 14 of the housing section 1 0. Housing section 10 has a plurality of contact-retaining channels 1 2 and terminal-retaining channels 14 , which are separated by a plurality of vertical walls 1 1 extending upwardly from base plate 13. Flange portions 15 are at both sides of housing section 1 0 as part of outer walls 1 1 . Some of the vertical walls 1 1 have a truncated cone projection l i b on the rear portion thereof. These projections 116 are used to align the housing section 10 and the housing section 20 when it is stacked thereon , and to electrically connect both housing sections . Stepped recesses 23a are formed in the bottom surface of the housing section 20 at positions corresponding to that of projections 1 1 b . Therefore , the projections 11 b align the housing sections 10 ,20 by engaging with recesses 23a , as shown in Figure 5. In addition , by removing the insulation coating 10a , 20a on the projections 1 1 b and recesses 23a , the housing sections 1 0 , 20 can be electrical ly connected . Electrical connection between housing sections 10 ,20 can be conducted by projections 1 1 b piercing the insulation coating 10a , 20a when mating with recesses 23a . In such a case, the insulation coatings 10a , 20a can cover projections 1 1 b and recesse's 23a instead of leaving them exposed . The other housing sections and cover section are aligned and electrically connected in the same manner as that of housing sections 10 , 20.
The plurality of contacts 17 extend along the contact-retaining channels 12 and the terminal-retaining channels 14. Contacts 17 are arranged laterally and are retained in position in the channels by dielectric member 18 , which is disposed in recesses 1 1 c in walls 1 1 and into channels 12 , 14 at the junction therebetween . Dielectric member 18 is preferably insert molded in position , but it can be a molded member that is frictionally inserted in recesses 11c and contains other recesses in which terminal sections 17c are disposed.
Opposed projections 1 1 a projecting slightly inward are located on vertical walls 11 at a position corresponding to that of leaf spring members 17b of the contacts 17. As shown in Figures 6 and 8 , projections 11 a are engaged by the spring members 17b when the contacts 17 are received and retained inside the retaining channels 12 , 14. In the case that the whole surface of the housing section 10 has insulation thereon , no electrical connection between the housing section 10 and contacts 17 is made when the leaf spring members 17b engage the insulated projections 11a as shown in Figure 8. However , in the case that no insulation covers projections 11a , spring members 17c electrically engage these projections thereby connecting such contacts 17 to the housing and ground . Accordingly , the housing sections 10-60 are grounded , and thus an effective elimination of cross talk between the contacts can be obtained . Moreover, the ground position for grounding the contacts to housing H can be selected as desired , and thus can be made suitable for the connection of any circuit. As explained above, according to this invention , each electrical contact can be received and retained in the retaining channels of housing sections made from a conductive material which are coated with a dielectric material and selectively connecting contacts to the interconnected housing sections . This eliminated cross talk by the housing sections and the occurrence of noise is prevented.
