Abstract

The invention belongs to the field of electric technique, and provides an SC adapter of an improved structure. The SC adapter comprises an outer shell, a plug and a ceramic sleeve, wherein a containing space used for containing the ceramic sleeve is formed in the inner middle position after the plug and the outer shell are assembled, the upper end and the lower end of the plug are respectively provided with a fixing end fastener portion, each fixing end fastener portion is provided with a connector plug, fastener arms will deform and rotate towards the outer side direction when the connector plugs are in interaction with fastener heads, 60-degree inclination is formed between each fastener head and the vertical Y direction, the length of each fastener arm is 5.56cm, and 95-degree inclination is formed between the outer side of each fastener arm and the horizontal X length direction. According to the SC adapter, under the standard precondition that plugging and pulling force is less than 19.6N, pulling-out force is improved to 70N, and good reliability and safety are guaranteed. The whole SC adapter has very few parts and only uses three parts. Due to the design that the plug penetrates upwards from the lower portion of the outer shell and then is fastened through an inclined inverse buckle on the outer shell, the SC adapter has the advantages that few parts are used, production simplicity is achieved, and products are safe and reliable.

Description

A kind of SC adapter that improves structure

Technical field

The invention belongs to electronic technology field, relate to a kind of fiber optic communications devices, be specifically related to a kind of SC adapter that improves structure.

Background technology

At present, known SC adapter, conventionally all there are four or five parts, and need could produce and assembly with ultrasonic equipment, SC connector plug inserts SC adapter from the two ends of adapter, here according to the contact engaging and separating force of the demand SC connector plug of the standard of existing SC adapter and use and SC adapter, should be less than 19.6N, and pulling-out force should be greater than 40N, and pulling-out force is to be the bigger the better, because SC connector plug and adapter signal transmission are carrier by laser, and laser is very easy to burn to people's eyes, therefore the reliability leaking for optical transmission physical channel laser has very high requirement, during being connected with of SC connector plug and SC adapter in not attention situation, can bear the pulling force over 40N, if at this moment they are pulled and now have signal to transmit, laser is swept to people will cause certain injury, reliability and security are lower, simultaneously because number of components is more, produce assembling loaded down with trivial details, production cost is higher.

Summary of the invention

Technical matters to be solved by this invention is the present situation for prior art, and provides a kind of simple in structure, easy to assembly, the SC adapter of the improvement structure that reliability and security are good.

The present invention solves the problems of the technologies described above adopted technical scheme: a kind of SC adapter that improves structure, comprise shell body, card plug and ceramic sleeve, after described card plug and shell body assembling, on bosom position, be formed with the accommodation space of putting into for ceramic sleeve, it is characterized in that, the two ends up and down of described card plug are provided with stiff end pothook, on stiff end pothook, be provided with connector plug, described stiff end pothook comprises grab head and hook arm, when described connector plug and grab head interact, hook arm will be out of shape direction rotation laterally, described grab head and vertical Y direction have 60 ° of gradients, described hook arm lengths is 5.65cm, outside described hook arm, have with X horizontal length direction and become 95 ° of gradients, described hook arm outwards opens the process of being out of shape gradually from lower to upper in X horizontal length direction for hook arm.

The measure of taking for optimization such scheme specifically comprises:

In above-mentioned a kind of SC adapter that improves structure, described shell body is structure as a whole, described shell body comprises main part and lower sleeve portion, in described main part, there is the space packing into for card plug, on the madial wall of main part, be provided with and block the ramp down that plug matches and buckle, described ramp down button from bottom to top tilted direction progressively broadens, described lower sleeve portion is connected to the centre position of main part, in lower sleeve portion, there is the lower accommodation space of putting into for ceramic sleeve, the bore of described lower sleeve portion end is less than the diameter of ceramic sleeve, between main part and grab head, there is the elastic space for the rotation of grab head.

In above-mentioned a kind of SC adapter that improves structure, described card plug is also structure as a whole, the stiff end pothook and the upper bush portion that comprise two ends, on described stiff end pothook side dual-side, there is the shoulder block matching with ramp down button, shoulder block can from bottom to top slide into ramp down and buckle portion along the tilted direction of ramp down button, described upper bush portion is connected to the centre position of stiff end pothook, in upper bush portion, there is the upper accommodation space of putting into for ceramic sleeve, the bore of described upper bush portion end is less than the diameter of ceramic sleeve, described upper bush portion and lower sleeve portion close the accommodation space that rear formation is put into for ceramic sleeve mutually.

In above-mentioned a kind of SC adapter that improves structure, the other elastic opening that offers of described ramp down button, when described card plug and shell body are installed, shoulder block extruding ramp down is buckled to the motion of elastic opening direction, and shoulder block slips into ramp down button and retreads back-off again from elastic opening direction homing.

In above-mentioned a kind of SC adapter that improves structure, the transverse width diameter of described grab head is greater than the transverse width diameter of hook arm.Guarantee so on the one hand the intensity of grab head, made on the other hand hook arm possess good elasticity capacity.

Compared with prior art, the invention has the advantages that:

1, guaranteeing that contact engaging and separating force is less than under the standard prerequisite of 19.6N, improving pulling-out force to 70N, guaranteeing good reliability and security;

2, SC adapter shell body is one, exquisite appearance, four grabs of card SC connector plug all on card plug, be a secondary Mold Making out, so more guaranteed the right alignment after two SC connector plugs insertions;

3, whole SC adapter parts are considerably less, three parts have only been used, produce assembling very simple, only ceramic sleeve need be put into the accommodation space of ceramic sleeve, then insert shell body, by the design that upwards then string fastens by the ramp down shell from the bottom of shell of card plug, reach product parts few, produce the simple and easy and reliable advantage of product safety.
