Description

Technical Field

[0001] The utility model relates to the technical field of installation assistance, in particular to a quick installation fixture for a circuit board interface terminal. Background Art

[0002] During the assembly process of the circuit board and the interface terminal, in order to allow the interface terminal to be accurately installed in the specified hole position of the circuit board, it is generally necessary to manually place the interface terminal on the circuit board first, and then press the entire interface terminal as a whole onto the accessory body, and fix it through the bottom pin welding. However, since the height of the pins needs to be very precise, if the pins are pressed separately, uneven conditions may occur, resulting in the inability to install subsequent components and requiring multiple adjustments. This process is not only time-consuming and labor-intensive, but also inefficient. To this end, our company began to study a fixture that can quickly install circuit board interface terminals. Utility Model Content

[0003] In order to solve the technical problem proposed in the background technology that the interface terminal installed on the circuit board needs to have very precise pin height, if the pins are pressed separately, unevenness may occur, resulting in the inability to install subsequent components and requiring multiple adjustments.

[0004] The utility model provides a quick installation jig for circuit board interface terminals, and the technical scheme adopted is as follows: a quick installation jig for circuit board interface terminals, comprising a circuit board, an interface terminal assembly and a pressing plate, characterized in that a plurality of plug holes are arranged on the circuit board, the interface terminal assemblies are installed on the plug holes, and the interface terminal assemblies are pressed into the plug holes by the pressing plate and fixed.

[0005] Preferably, the interface terminal assembly includes a coverless shell, pins a and pins b. A group of pins a are first fixedly set in the coverless shell, and a group of pins b are set between pins a and pins a. Pins b penetrate the bottom of the coverless shell and pins b slide in the coverless shell. There is friction between pins b and the coverless shell and the coverless shell will not fall off.

[0006] Preferably, a group of pinholes are evenly arranged on the pressing plate to prevent the pins b from twisting and deforming during the pressing process.

[0007] Compared with the prior art, the utility model has the following effects:

[0008] By changing the fixation of the uncovered housing and pin a in the interface terminal assembly, the installation and positioning can be quickly carried out. The pin b in the uncovered housing can be pressed simultaneously by the pressure plate and is at the same level as pin a. It only takes a few seconds to install an interface terminal on a circuit board and then complete the subsequent welding. Compared with the existing technology, the device has no error during installation, greatly improves work efficiency, and thus saves a lot of labor costs. In the fiercely competitive industrial production, the competitiveness of the company's products is guaranteed, and it is suitable for comprehensive promotion and application.
