Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The present invention includes, but is not limited to, the following examples.

[0022] In order to overcome the deficiencies in the prior art, the present invention first needs to determine the problem:

[0023] a) The position of the PCB during crimping, that is: whether the PCB is placed horizontally or vertically;

[0024] b) Which side of the socket is used as the reference plane when crimping;

[0025] c) Which material is used for the tooling;

[0026] d) What kind of pressure device is used;

[0027] Determination of problem a): If the PCB is placed horizontally during crimping, the crimping surface is the positioning surface, and the crimping effect cannot be guaranteed;

[0028] Determination of problem b): According to the relative position of the printed board and the socket after crimping, the PCB should be placed vertically when...

Abstract

The invention provides a CPCI (contact peripheral component interconnect) socket crimping tool which comprises a comb-tooth structural part and a positioning shoulder part. The positioning shoulder part is a rectangular block with a step surface on one side. The height of the small thickness part of the step surface is larger than the width of a lead surface of a CPCI socket. The comb-tooth structural part is also a rectangular block with a plurality of rows of projecting comb teeth on one side. When the CPCI socket is vertically placed on the steps surface of the positioning shoulder part, gaps of the rows of comb teeth right face to columns of pins of the CPCI socket. The CPCI ensures crimping to be completed by one time and is friendly to printed circuit boards after crimping.

Description

technical field [0001] The invention relates to a crimping tool, which is used for crimping a CPCI socket and a printed board. Background technique [0002] On traditional printed boards, the sockets are all through-hole plug-in components, and the sockets are installed according to the socket pin holes on the printed board, and soldered with a soldering iron on the soldering surface of the printed board to realize the electrical connection between the socket and the printed board and mechanical connection. [0003] In recent years, some circuit designers have adopted a computer bus socket, that is, the CPCI socket. The socket in this package is connected to the printed board by crimping. Compared with soldering sockets, crimping sockets have better consistency of pin crimping points, the operating frequency is generally above several G, and the pin density is high, which brings new challenges to the electronic assembly process. [0004] Figure 1 is a schematic diagram of...
