Description

Electronic card coupler

Technical field

The utility model is relevant for a kind of electronic card coupler, especially refer to that a kind of plastic cement body both sides at a connector are embedded an earthing component respectively, make each this earthing component be respectively equipped with a U type section section, make this U type section section accordingly with the side arm double team of this plastic cement body in interior, with the intensity of this section of reinforcement side arm.

Background technology

At present generally be applied to connect the connector of electronic cards, as shown in Figure 1, the connector that this case disclosed, comprise: a plastic cement body 91, the base portion of this plastic cement body 91 is embedded most terminals 911 side by side, the electronic cards of being inserted to be electrically connected, order is at the both sides of this plastic cement body 91 difference projection one side arm 912; And two fixation spring tab 92, each this fixation spring tab 92 contains an inserted sheet 921, to embed accordingly in this plastic cement body 91, and at this fixation spring tab 92 projection one sidewall 923 radially, in order to the outside of the side arm 912 that is posted by this plastic cement body 91, with the side arm 912 of this plastic cement body 91 of reinforcement, when under user mode, when taking out electronic cards, attempt is lowered because of outwards supporting the possibility that two side arms 912,912 causes two side arms 912,912 to rupture.In addition at these fixation spring tab 92 downward projection one joint fasteners 922, so that be attached to the surface of circuit board.

But above-mentioned connector construction still has following shortcoming:

1. in the process of the jack 913 that the inserted sheet 921 of fixation spring tab 92 is inserted into side arm 912, because the side arm 912 of plastic cement body 91 is one very long cantilever-shaped, and be plastic cement material, so its structure is very fragile and very easily rupture.

2. under user mode, because the side arm 912 of plastic cement body 91 be the plastic cement material of long cantilever shape very, so its structure fragility very.Because in the process of taking out electronic cards, must the two side arms 912,912 that this structure is very fragile outwards pull open respectively, therefore very easily cause two side arms 912,912 fractures because of the application of force is improper, undermine useful life.

3. each fixation spring tab 92 there is no suitable ground structure and contacts the formation grounded circuit with the electronic cards of being inserted, and therefore easily influences the signal output quality of electronic cards.

4. in the process of the jack 913 that the inserted sheet 921 of fixation spring tab 92 is inserted into plastic cement body 91, the inserted sheet 921 of fixation spring tab 92 very easily also follows deviation to exceed specification because of inserting the askew joint fastener 922 that causes, cause joint fastener 922 can't correctly contact with the circuit board (not shown) of below, cause loose contact, but the producer can't know in advance.So when fixation spring tab 92 deviations be plugged in plastic cement body 91 after, and stick together as the surface with circuit board and to add man-hour, will cause the substandard products of loose contact.

This case inventor supervises in this, through further research innovation, discloses a kind of electronic card coupler.
