PCB (printed circuit board)-passing type connector capable of observing and checking back annular space

Abstract

The invention relates to a PCB (printed circuit board) passing type connector capable of back annular space observation and verification, which comprises a PCB, a positive U-shaped female terminal anda positive U-shaped male terminal, and is characterized in that a plug hole is formed in the PCB; wherein two ends of the positive U-shaped female terminal are fixedly connected to the PCB, and the positive U-shaped female terminal is provided with a connecting hole; the male terminal comprises a columnar connecting pin with a tip, the connecting pin firstly penetrates through the connecting holeand then penetrates through the inserting hole, the outer wall face of the connecting pin and the connecting hole form a four-section contact structure, and meanwhile forward observation and verification of the four-section contact structure can be achieved in a visual annular space formed by the back face of the inserting hole 11 and the male terminal 3. Compared with the prior art, the four-section contact structure is realized through a connecting structure formed by the positive U-shaped female terminal and the PCB, and meanwhile, a clear picture of the contact area can be obtained through image acquisition equipment, so that rapid machine inspection of an industrial robot is realized.

Description

technical field [0001] The invention relates to a connector, in particular to a through-PCB connector capable of observing and verifying the ring gap at the back. Background technique [0002] The connector terminal includes a male terminal and a female terminal, the male terminal has a plug tongue and a male connection part, and the male connection part is connected to the plug tongue. The receptacle has a receptacle base and a receptacle connecting portion connected to the receptacle base. When in use, the insertion tongue of the male terminal is inserted into the female end insertion groove of the female terminal. [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 ...

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
