Description

Row's mother socket of tin is leaked in a kind of anti-welding

Technical field

The utility model relates to a kind of plug connector, and particularly row's mother socket of tin is leaked in a kind of anti-welding.

Background technology

Anti-welding is leaked row's mother socket of tin as a kind of plug connector, and it has the very installation interface of standard and good cost performance, and product is very ripe, and in addition, its terminal is that opening is the U-shaped structure of horizontal direction, and contact form is three contacts.Except above advantage, it also possesses very superior contact performance, therefore be arranged in a large number in various electronic equipments.Its installation form is for being manually inserted into above PCB, re-use artificial flatiron welding, but along with the raising of cost of labor and the price competition of market fierceness, to allow the development of product be subject to restriction to a certain extent, a lot of producers have to use machine wave soldering to replace artificial welding for reducing costs.But having a lot of pcb boards is double sided board, traditional wave soldering cannot meet the requirement of welding, now have to use selectivity wave soldering, fix product by making special clamping tool, then in the time crossing tin stove, reach the object of welding by the tin upwards spraying.But because the tin mobility under liquid condition is very good and upwards spray always, add existing anti-welding and leak the U-shaped structure that row's mother socket terminal of tin is designed to often open, the in the situation that of selectivity wave soldering, U-shaped mouth is by whole stannizes, thereby cause corresponding contact pin to insert, cause produced product rejection rate high.

Utility model content

The purpose of this utility model is to provide a kind of row's mother socket of anti-welding leakage tin, to overcome prior art above shortcomings.

The purpose of this utility model is to be achieved through the following technical solutions:

Row's mother socket of tin is leaked in a kind of anti-welding, comprise glue core, terminal and pcb board, on described glue core and pcb board, be equipped with the jack suitable with terminal, described terminal comprises terminal head, opening is towards the U-lag of horizontal direction, terminal pins root of the tail portion and terminal backshank, described U-lag two ends splicing ear head and terminal pins root of the tail portion, described terminal head comprises the three butt sub-connection branches that are located at respectively three side wall lower ends of U-lag, between described terminal pins root of the tail portion and terminal backshank, it is arc-shaped transition, the lateral sidewalls of described terminal pins root of the tail portion is provided with widens layer, the lateral wall of described terminal backshank is provided with reinforcement, on the both sides transverse arm of described U-lag, top is equipped with groove.

Further, described reinforcement distributes along the longitudinal extension direction of terminal backshank.

Further, be connected between described terminal pins root of the tail portion and the terminal backshank size of arc and the size of pcb board jack is suitable.

The beneficial effects of the utility model are: on the widening of arc design by between terminal root and terminal backshank, terminal root, terminal backshank, arrange and on reinforcement and U-lag, groove is set and has solved the problem that selectivity wave soldering is leaked tin.

Brief description of the drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Embodiment

As Figure 1-5, row's mother socket of tin is leaked in a kind of anti-welding described in the utility model embodiment, comprise glue core 1, terminal 2 and pcb board 3, on described glue core 1 and pcb board 3, be equipped with the jack suitable with terminal 2, described terminal 2 comprises terminal head 4, opening U-lag 5, terminal pins root of the tail portion 6 and the terminal backshank 7 towards horizontal direction, described U-lag 5 two ends splicing ear heads 4 and terminal pins root of the tail portion 6, described terminal head 4 comprises the three butt sub-connection branches that are located at respectively 5 three side wall lower ends of U-lag.

Between described terminal pins root of the tail portion 6 and terminal backshank 7, it is arc-shaped transition, the size of the jack on the size of described arc and pcb board 3 is suitable, preferably, distance 12 between aperture described arc reduces terminal and inserts on being of a size of to greatest extent time and on pcb board jack 11, the lateral sidewalls of entering described terminal pins root of the tail portion 6 is provided with widens layer 8, the described layer 8 of widening can effectively stop while welding that tin is toward upper punch, the lateral wall of described terminal backshank 7 is provided with reinforcement 9, described reinforcement 9 distributes along the longitudinal extension direction of terminal backshank 7, not only can increase the intensity of terminal backshank 7, can also increase the thickness of terminal backshank 7, gap while insertion to reach minimizing and between pcb board 3, on the both sides transverse arm of described U-lag 5, top is equipped with groove 10, distance when described groove 10 has increased welding between tin and U-lag 5, while avoiding welding, U-lag 5 adsorbs the tin up spraying, the notch depth of described groove 10 can be concrete actual conditions and determine.

In sum, on the widening of the design of the arc by between terminal root and terminal backshank, terminal root, terminal backshank, arrange and on reinforcement and U-lag, groove is set and has solved the problem that selectivity wave soldering is leaked tin.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
