An over-pcb board connector capable of frontal observation and verification

Abstract

The invention relates to an over-PCB board connector capable of frontal observation and verification, comprising a PCB board, an inverted U-shaped female terminal and a male terminal, wherein the PCB board is provided with a plug-in hole; both ends of the inverted U-shaped female terminal are fixedly connected to On the PCB board, the inverted U-shaped female terminal is provided with a connection hole; the male terminal includes a cylindrical connection pin with a tip, the connection pin first passes through the insertion hole and then passes through the connection hole, and the connection pin The outer wall surface of the contact hole and the connecting hole form a 4-segment contact structure, and at the same time, the positive observation and verification of the 4-segment contact structure can be realized from the front side of the inverted U-shaped female terminal. Compared with the prior art, the present invention realizes the 4-segment contact structure through the connection structure formed by the inverted U-shaped female terminal and the PCB board, and at the same time can realize the forward observation of the 4-segment contact structure from the front side of the inverted U-shaped female terminal. For verification, clear photos of the contact area can be obtained through image acquisition equipment, so as to realize rapid machine inspection of industrial robots.

Description

technical field [0001] The present invention relates to a connector, in particular to an over-PCB board connector which can be observed and verified from the front. Background technique [0002] The connector terminal includes a male terminal and a female terminal. The male terminal has a plug-in tongue and a male-end connecting part, and the male-end connecting part is connected with the plug-in tongue. The female terminal has a female end base and a female end connecting portion, and the female end connecting portion is connected with the female end base. When in use, the insertion tongue of the male terminal is inserted into the female terminal insertion groove of the female terminal. [0003] However, when the connector is in use, because the plug tongue of the male terminal and the female terminal socket of the female terminal are in single-sided single contact, the contact area is small, the contact resistance value is relatively large, the heat generation is large, a...

Problems solved by technology

[0003] However, when the connector is in use, because the insertion tongue of the male terminal and the female terminal insertion groove of the female terminal are single-sided and single-contact, the contact area is small, the contact impedance value is relatively large, the heat generation is large, and the heat dissipation effect is poor. , which poses a safety hazard to the

[0004] In the prior art, the male end and the female end of the electrical connector are either connected by wires, which is very troublesome and has the defect of weak connection, or a male-female butt joint connection is used, and the existing electrical connection is carefully analyzed. According to the terminal structure of the device, it is not difficult to find that most of the male terminals and female terminals directly form a single raised shrapnel contact at the position where they contact each other. The shrapnel has weak elasticity, poor contact contact tightness, unstable electrical connection, and poor reliability. There is a need for improvement

[0005] At present, the rise of computer vision algorithms provides a new idea for the verification of connector connection stability. The connection area can be visually identified through the algorithm, and the analysis of the tightness of the contact points can be realized through the analysis of the boundary contour. However, the current connector The contact positions of the male terminal and the female terminal are both inside the connection structure, which creates obstacles to the collection of pictures
