To achieve the above object, the present invention provides following technical scheme:
A kind of connector, including rear shell and fore shell, the rear shell include upper rear shell and lower rear shell, upper rear shell and lower rear shell one Shaping, upper rear shell and lower rear shell surround an accommodation space, the afterbody edge of lower rear shell extends back and arc be pulled up formed with Connection ring, rear shell end are provided with the connector that is adapted to fore shell, and the fore shell includes upper fore shell and lower fore shell, upper fore shell and it is lower before Shell is integrally formed, and is provided with cavity in upper fore shell and lower fore shell, outer glue core, terminal and snap fit, terminal tip portions are provided with the cavity Provided with terminal leg, terminal both sides are provided with two snap fits, and snap fit is fixedly mounted inside the housing by outer glue core, and snap fit with it is outer Gap is provided between glue core, the snap fit extends upward snap fit leg, and two snap fit legs are oppositely arranged, and snap fit leg is located at The both sides of terminal leg, terminal leg are designed to K pin shapes, and snap fit leg section is in into K pin shapes.
Further, it is arranged with pcb board between the terminal leg.
Further, the outer glue in-core is machined with EMC shell fragments, and EMC shell fragments abut with fore shell, and the head of EMC shell fragments is Spring-piece type.
Further, interior glue core is embedded with the terminal body, interior glue core front end is provided with recess, and pcb board front end is provided with Projection, projection are set with mating recesses.
Further, the pcb board front end is fixedly connected by tin cream with fore shell, snap fit.
Compared with prior art, the beneficial effects of the invention are as follows:
1. snap fit leg and terminal leg are designed to K pin shapes, are advantageous to insert pcb board, increase Strong welderings Tin, protect snap fit with Time Indeed And the fixation and positioning of Duan With pcb boards;
The head of 2.EMC shell fragments is spring-piece type so that EMC shell fragments performance is more stable, and EMC shell fragments are short using spring-piece type and shell Road, ensure the reliability of contact;
3.PCB plates are designed to that penetration type can be positioned preferably with fixing;
Tin cream above 4.PCB plates after high temperature fore shell, snap fit, pcb board short circuit together, so can effectively prevent electrostatic Occur.
