Description

Pin connector

[technical field]

The utility model is to provide a kind of pin connector, and particularly a kind of structure is little and can realize the pin connector of forward, oppositely grafting.

[background technology]

Existing electric connector is mostly that one direction is inserted, this just requires that user needs first to judge that grafting is carried out again in direction in the process of grafting, concerning extremely inconvenient user, be easy to damage connector, so the structure that each manufacturer takes various way to improve electric connector one after another carrys out person easy to use, be necessary to improve existing conventional structure in fact, to design a kind of pin connector realizing forward, oppositely grafting.

The earth terminal of existing electric connector is set directly on shell, but the electric connector less for overall dimensions illustrates, earth terminal is just difficult to be set directly on shell, therefore need to improve the structure of typical electrical connector, to adapt to the needs installing earth terminal on the electric connector that overall dimensions are less.

Existing electric connector, in order to pin butt connector, prevents butt connector from coming off and metal shell outside coated connector tears a pair shell fragment, and realizing above object; So the defect of this design is, the anti-electromagnetic interference performance of this electric connector dies down, the performance of interfering conductor.

Therefore how to improve the defect of prior art, it is the target of desired most ardently in the art improvement at present.

[summary of the invention]

In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of pin connector, and it can realize forward, oppositely grafting; It can be grounded in less connector, strengthens contact engaging and separating force; It can strengthen anti-electromagnetic interference performance while preventing butt connector from coming off.

The utility model is to provide and be coated on the shielding casing on insulating body; The Plug Division that described insulating body includes matrix and extends to form forward from matrix, described Plug Division is provided with a grafting space, and encloses the roof in this grafting space, diapire and two side, and this roof, diapire are respectively equipped with plural terminals conduit; Described conducting terminal module includes the upper terminal module being arranged at this roof terminal conduit and the lower terminal module being arranged at this diapire terminal conduit, be equipped be fixed on insulating body fixed part, to extend to form the elastic contact part, the self-retaining portion that are stretched on this grafting space along fixed part to one end and extend to the other end and expose the weld part of insulating body, its: the sub-modular structure of this upper and lower end is identical, and the elastic contact part of this upper and lower end submodule group goes to upper and lower the symmetrical setting of two rows; This Plug Division is provided with the through hole connected with this grafting space, also be provided with a locking terminal, this locking terminal is provided with the holding parts being immobilizated in insulating body, extend from holding parts and be stretched on the snap close shell fragment in this grafting space by this through hole, and extend along holding parts to the other end and expose the afterbody of insulating body; This Plug Division is provided with an assembling grove connected with this grafting space, also be provided with a grounding elastic part, this grounding elastic part is provided with the assembled portion being assembled in this assembling grove, connect the connecting portion of this assembled portion, and to extend from connecting portion bending and to convexedly stretch in the elastic portion in this grafting space, this elastic portion comparatively this elastic contact part further from this matrix.

Compared to prior art, the utility model can realize two-way grafting, the effect that also can be grounded in ultra-thin electric connector, strengthens the anti-electromagnetic interference performance of this connector while also can realizing pinning butt connector.
