Embodiment 1

[0039] In the process of PCB board processing, it is often necessary to install different connectors on the surface of the PCB board. The more commonly used installation method is crimping connection. In PCB design, if the system needs to connect all or part of the signals of the two crimped connectors, it can be realized by using the method of pressing the front and back connectors in this application. In this embodiment, a plurality of crimping holes are provided on the front and back of the PCB board, and these crimping holes are respectively used to connect a plurality of front connectors and rear connectors. Moreover, in this embodiment, at least one row of signals in a group of front and back connectors connected to the PCB board need to be directly connected. In this embodiment, at least one row of signals needs to be directly connected. The front connector and the back connector are defined as a group Matching front and back connectors.

Embodiment 2

[0052] exist figure 1 and figure 2 On the basis of the illustrated embodiment see image 3 , image 3 It is a schematic flowchart of a crimping method for a connector on the front and back of a PCB provided in the embodiment of the present application.

[0053] Depend on image 3 It can be seen that the crimping method of the PCB front and back connectors in this embodiment mainly includes the following process:

[0054] S1: Determine whether at least one row of signals can be directly connected between the front connector and the back connector connected to the PCB, whether the center distance between the pins of the front connector and the back connector is consistent, and whether the thickness of the PCB is greater than the front pressure The sum of the minimum depth of the contact hole and the minimum depth of the reverse crimp hole.

[0055] Among them, the center distance of the pins includes the center distance of the pins in the horizontal direction and the cente...

Abstract

The present application discloses a method for crimping a PCB board and a front connector and a back connector of the PCB. Crimping holes of the PCB board include a first crimping hole directly connected and a second crimping hole designed as a blind hole. The first crimping hole is used to connect a direct connection signal, and the second crimping hole is used to connect a non-direct connectionsignal. The method comprises: first determining whether the crimping condition of the front and back connectors of the PCB is met, if the crimping condition is met, arrange the direct connection signal in a continuous area of a pin of the front connector and the back connector, arrange the non-direct connection signal in the non-direct connection area of the pin of the front connector and the backconnector; the front connector and the back connector for transmitting the direct connection signal are crimped by the directly connected crimping hole, the front connector and the back connector fortransmitting the non-direct connection signal are crimped by blind hole. Through the application, the number and length of the traces of the PCB board can be reduced, the cost and difficulty of the trace line can be reduced, and the design efficiency of the PCB board can be improved.

Description

technical field [0001] The present application relates to the technical field of press-fitting PCB connectors, in particular to a method for crimping PCB boards and connectors on the front and back sides of the PCB. Background technique [0002] In the process of PCB board processing, it often involves installing different connectors on the surface of the PCB. The most commonly used installation method is crimping connection. Specifically, crimping holes are designed on the PCB, pins are designed on the connector, and the connector on the surface of the PCB is installed by crimping the pins of the connector to the crimping holes of the PCB. Therefore, when the front and back sides of the PCB board are provided with pressure connectors, the connectors are respectively crimped on the front and back sides of the PCB board, and the two connectors must be of the same type to perform pressure connection. The PCB board design according to different connectors and the crimping meth...
