Description

Electric connector

The utility model refers to a kind of many ports module connector especially relevant for a kind of electric connector.

Module connector is used very general in communication network, and some computer equipments also often adopt module connector when miscellaneous equipment carries out access and communicates by letter.When computer equipment is desired to carry out the data message access with a plurality of equipment simultaneously and carried, then will be equipped with the Bu Kou of a plurality of module connectors.Occupy usage space in the computer equipment for saving cost and reducing connector, the many ports module connector that a plurality of module connectors is integrated in one just arises at the historic moment.This many ports module connector is provided with plurality of module connector Bu Kou on the insulating body of an integral body, this Bu Kou is installed on the printed circuit board (PCB) with arrangement mode arranged side by side for to place the insulating body of one to form several maintainance block group groups that are mounted with plurality of conductive terminals.

The case technology can be with reference to cases such as No. the 85103162nd, the 5th, 879, No. 199 patents of the U.S. and Taiwan patent applications before relevant.In this existing design, the conducting terminal of module connector and the maintainance block that the loads conducting terminal formation terminal module that is formed in one.But when conducting terminal and maintainance block when one-body molded, are needed to adopt special mould, the technical sophistication that operates is unfavorable for reducing manufacturing cost.In addition, see also the 5th, 580, No. 274 patents of the U.S., this case has disclosed a kind of prior art of avoiding using aforementioned one-body molded technology, and it inserts terminal to assemble out terminal module then for molding maintainance block earlier.But this prior art if bend out termination end fully again after terminal is inserted maintainance block, then is difficult to realize because of termination end can't bend.Like this, must first termination end bend out, then terminal is inserted maintainance block, bend out the termination contact end again, the strip bearing part excision that will be connected with termination end at last terminal.Such production process, at terminal through bending (bending out termination end) bad afterwards clamping, and the bad application of force when being inserted into maintainance block, it is crooked that terminal is taken place, and causes that quality is bad.In addition, because the final extension bit of termination end is equipped with two rows, must be with two separately operations of row, after promptly earlier a socket being gone into to assemble and excising the strip bearing part, insert assembling second row again.Like this, when making a terminal module, same work must repeat to do twice.This is for improving production capacity, and significant adverse reduces cost.

The purpose of this utility model is to provide a kind of electric connector, its maintainance block has appropriate structure, make when the manufacturing terminal submodule, can after being inserted maintainance block, terminal just bend out termination end and contact jaw, and the termination end of arranging terminal can bend simultaneously, thereby can reduce fabrication schedule, be easy to make, reduce production costs.

For achieving the above object, the utility model electric connector is organized on insulating body and is equipped with plurality of terminals module and some light-emitting diodes.Wherein insulating body is provided with the mouth of accommodating for the butt connector insertion, and terminal module comprises maintainance block and be loaded into plurality of terminals on the maintainance block, maintainance block comprises the conduit that upper surface, lower surface, some horizontal grooves and self-sustaining piece upper surface are offered and be connected with described horizontal groove downwards, and wherein end is the basal surface that runs through maintainance block downwards after each horizontal groove.The interlude of terminal is the flat plant and is fixed in the corresponding horizontal groove of maintainance block, its front end extends from horizontal groove the place ahead, through being bent to form the contact jaw that is positioned at maintainance block top, and its rear end is bent to form the termination end that is positioned at the maintainance block below downwards from aforementioned conduit place.

Owing to adopt such scheme, maintainance block has appropriate structure, make when the manufacturing terminal submodule, can after being inserted maintainance block, terminal just bend out termination end and contact jaw, and the termination end of arranging terminal can bend simultaneously, thereby can reduce fabrication schedule, is easy to make, production cost is low.
