Description

WTB connector

Technical Field

The utility model relates to a WTB connector that easily shaping and connection are firm.

Background

Generally, in various electronic systems, an electrical connector for electrical connection and signal transmission between devices, assemblies and assemblies, and systems is a basic element necessary for forming a complete system, wherein, the WTB connector is widely used in the field of electrical equipment as an electrical connector for connecting a flat cable and a circuit board. Currently, WTB connectors used in the market have a number of disadvantages: firstly, most of the WTB connectors in the market are made of plastic materials, the protrusions on the wire ends are directly inserted into the board ends, and the fixed connection is realized by matching the clamping points on the side walls of the board ends; secondly, current WTB connector has lateral direction sunken and/or side opening on board end plastic main part, need set up the side direction parting mechanism of loosing core in the mould, not only can improve the mould cost, can reduce production efficiency moreover, shorten the mould life-span, increase the maintenance rate, still can leave the excessive limit in parting surface department simultaneously, increase and mould a finishing work volume.

The utility model discloses an overcome above-mentioned defect, carried out profitable improvement.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the above-mentioned not enough among the prior art, provide an easy shaping and connect firm WTB connector.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a WTB connector comprises a board end plastic main body, a metal fixing element and a plurality of metal terminals, wherein the metal terminals are accommodated in the board end plastic main body, and the plastic main body at the plate end is provided with a plurality of channels, the plurality of metal terminals respectively penetrate through the plurality of channels in a one-to-one correspondence manner, it is characterized in that two ends of the plate end plastic main body are symmetrically provided with two lugs, the inner sides of the lugs are both provided with the metal fixing elements, the metal fixing elements are provided with blind hole-shaped grooves, when the wire end is inserted into the board end, the blind hole-shaped groove is clamped with the first bulge on the wire end, the edge of the top of the plastic main body of the board end, which is far away from the wire end, is provided with a clamping hole, the clamping hole can be clamped with the second bulge on the wire end, the board end plastic main body is used for assisting in fixing the wire end, and the edge of one side, close to the wire end, of the top of the board end plastic main body is also provided with a 1 st PIN marking position.

Further, the edge of the blind hole-shaped groove is preferably curved arc-shaped.

Furthermore, the metal fixing element is made of copper.

The utility model has the advantages that: in the utility model, two lugs are symmetrically arranged at two ends of the plate end plastic main body, metal fixing elements are arranged at the inner sides of the two lugs, blind hole-shaped grooves matched with the protrusions on the wire end in a clamping manner are arranged on the metal fixing elements, and the edges of the blind hole-shaped grooves are preferably curved surface arcs; in addition, through drawing through the card hole on the board end plastic main part top surface to the top edge, with the 1 st PIN sign displacement to another edge relative with the card hole for forming die can be simple open and shut from top to bottom, need not set up the side direction parting in the mould and loose the core the structure, thereby increased mould stability, product size precision rises simultaneously, has reduced manufacturing cost.
