Definitions
- the invention relates to a shielded electrical plug connector with electrical terminal elements which have contact portions for the contacting of complementary contacts, the contact portions protruding out of an insulating housing.
- the invention also relates to an electrical plug connector with electrical terminal elements which have contact portions for the contacting of complementary contacts, which have terminal portions for connection with an electrical conductor, for example on a printed circuit board, and which have intermediate portions which connect the contact portions to the terminal portions, the terminal elements are combined in columns to form terminal subassemblies, the intermediate portions are fastened in or on an insulating rib and the contact portions protrude out of the rib, and with a shield which shields the individual terminal subassemblies from one another.
- EP 422 785 Bl discloses an impedance-matched rear- panel plug connector.
- This is a rectangular electrical connector with an insulating housing with pin-receiving openings in a front contact side of the housing, for receiving contact pins of a complementary connector.
- the pin-receiving openings are in connection with pin- receiving passages which extend to a rear side of the housing.
- the openings and the passages are arranged in a group of columns and rows.
- the electrical connector has electrical terminals with contact portions arranged in the pin-receiving passages, terminal portions for connection with a printed circuit board and intermediate portions which connect the contact portions and the terminal portions.
- the electrical terminals are combined in columns to form terminal subassemblies.
- terminal subassembly The intermediate portions of one terminal subassembly are enclosed within a moulded insulating rib.
- the terminal subassemblies are arranged against the insulating housing in a position in which they lie next to one another with the contact portions in the pin-receiving passages of the insulating housing.
- Shielding elements may be arranged between the terminal subassemblies or between the insulating ribs in order to prevent crosstalk between neighbouring columns of terminals.
- a terminal subassembly is shielded on two sides by a shielding element in the region of the rib, the shielding elements merge with cage-like shields that surround the terminal portions of the terminals. Therefore, a closed shield, which can be connected by means of resilient elements to earth potential on a printed circuit board, is produced around the terminal portions.
- a cage-like shield it may be necessary to surround a single terminal with a cage-like shield or enclose terminals in pairs with a common cage-like shield. These pairs may either be formed within one terminal subassembly or between neighbouring terminal subassemblies. Also, if the intermediate portions of the terminals of one terminal subassembly are surrounded by an insulating rib, it is possible that this rib has, alongside the intermediate portions, grooves into which may be received further shielding parts, which are connected to the cage-like shield to shield the intermediate portions of the neighbouring terminals from one another.
- Figure 1 shows a perspective view of a terminal subassembly according to the present invention
- Figure 2 shows another perspective view of the same terminal subassembly
- Figure 3 shows an exploded representation of the terminal subassembly with the shielding elements
- Figure 4 shows an assembled perspective view of an alternative embodiment of the present invention
- Figure 5 shows a partially assembled perspective view of the pair of subassemblies shown in Figure 4;
- Figure 6 shows a perspective view of a cage-like shield portion for a pair of contact portions of the assembly of Figure 4;
- Figure 7 shows a perspective view of a cage-like shield portion for one contact portion of the assembly of Figure 4;
- Figure 8 shows a perspective view of a cage-like shield portion for two contact portions of the assembly of Figure 4;
- Figure 9 shows a partially exploded representation of another embodiment of a terminal subassembly according to the present invention with alternative shielding elements
- Figure 10 shows the assembled arrangement of the terminal subassembly of Figure 9;
- Figure 11 shows yet another embodiment of a terminal subassembly according to the present invention in an exploded representation with an alternative cage-like shield and a further shielding part; and
- Figure 12 shows the assembled arrangement corresponding to Figure 11.
- Figures 1 to 3 illustrate a terminal subassembly 1 which has five terminals 2, that each have a contact portion 3, a terminal portion 4 and an intermediate portion (which cannot be seen in the drawings) that connects the contact portion 3 to the terminal portion 4.
- the contact portions 3 have, in the present example, two opposite contact spring arms for the contacting of a contact pin or contact blade. A different design of contact portions 3 is conceivable.
- the terminal portions 4 have a press-in region 5, for pressing into a plated through hole in a circuit board. A different design of the terminal portions 4 is also quite possible.
- the intermediate portions are surrounded in the present example by an insulating rib 6.
- the insulating rib 6 keeps the terminal elements 2 in the prescribed arrangement.
- the rib 6 may be produced, for example, by encapsulating the terminals 2 by injection moulding.
- the terminals 2 may, however, also be located in corresponding channels in a prefabricated moulded part, which the rib 6 represents.
- shielding elements 7 and 8 Associated with the terminal subassembly 1 are two shielding elements 7 and 8.
- One such shielding element 7, 8 is arranged on each side of the rib 6.
- the shielding element 8 has, along a side which corresponds to the terminal portions 4, resilient elements 9 for contacting corresponding regions on the circuit board.
- the shielding elements 7, 8 On the side of the shielding elements 7, 8 corresponding to the contact portions 3, the shielding elements 7, 8 have punched-out lugs 10, some of which have been bent out of the plane of the shielding element 7, 8 by 90°.
- the next lug is located in the plane of the shielding element 7, 8. This achieves the effect that, when shielding elements 7, 8 are joined together, around each contact portion 3 there is produced a cagelike shield 11, which is formed by the lugs 10.
- each individual contact portion 3 can be shielded from the next.
- the crosstalk between the individual terminals 2 of a terminal subassembly 1 can be reduced.
- the shielding elements 7, 8 are produced as punched parts from a metal sheet.
- the cage-like shields 11 for the contact portions 3 are formed as one part with the shielding elements 7, 8. This makes the production of the cage-like shield particularly easy.
- FIG. 4 A further exemplary embodiment of the invention is represented in Figures 4 to 8.
- two terminal subassemblies 1' and 1'' which are arranged next to one another, are represented.
- the terminal subassemblies 1' and 1'' have terminals with contact portions 3 and terminal portions 4, as in the case of the previous exemplary embodiment.
- the shielding elements are in the form of a metallized coating 7' on the rib 6.
- the rib 6 may, for example, be made in the form of a circuit board on which the intermediate portions of the terminals are in the form of a metallized coating thereupon as circuit traces on which the contact portions 3 and terminal portions 4 are fastened by soldering processes.
- the rib 6 thus corresponds in this case to a printed circuit board which, for shielding, is coated with a metallized coating 7' which acts as a shielding element.
- the cage-like shields 11, 11', 11' ' are made of punched parts, as represented in Figures 6 to 8. These punched parts have contact prongs 13, which would be soldered to the metallized surface 7'. This may take place, for example, by the SMD (Surface Mounted Device) technique. As can be seen particularly clearly in Figure 4, it is then possible to surround individual contact portions with a cage-like shield 11, to surround two contact portions of one terminal subassembly 1'' with a cage-like shield 11' or to surround two contact portions 3 of two terminal subassemblies 1', 1'' with a cage-like shield 11''.
- SMD Surface Mounted Device
- FIG. 9 A further exemplary embodiment, similar to the exemplary embodiment of Figures 1 to 3, is represented in Figures 9 and 10.
- a terminal subassembly 1 with terminals with contact portions 3 and terminal portions 4, the intermediate portion of which is surrounded by an insulating rib 6.
- shielding elements 7 and 8 Provided on two sides of the insulating rib 6 are shielding elements 7 and 8, which have on the side with the contact portions further shields 11 surrounding each a pair of contact portions 3.
- a terminal subassembly 1 has terminals with contact portions 3 and terminal portions 4.
- One of the contact portions 3 is surrounded by a cage-like shield 11, which continues into shielding parts 14, which engage into grooves 15 on both sides of the rib 6 and surround an intermediate portion of a terminal element almost completely. This makes it possible also to shield the individual intermediate portions of the terminals of a terminal subassembly from one another. It is even conceivable to create a coaxial line in this way.
- the individual terminal subassemblies may be combined by parallel arrangements to form a plug-in connector.
