Description

Technical Field

[0001] The utility model relates to the technical field of board-to-board connectors, and particularly to a multi-purpose guiding socket. Background Technique

[0002] A connector, also known as a plug-in connector, a plug, and a socket, generally refers to an electrical connector, which is a device connecting two active devices, transmitting current or signals. The function of the connector is to build a communication bridge between the interrupted or isolated circuits in the circuit, so that the current can flow through and the circuit can achieve the predetermined function.

[0003] In the existing application of board-to-board connectors, when the connectors at both ends are inserted into each other, misalignment is likely to occur during the insertion, resulting in damage to the connectors. Therefore, the utility model provides a multi-purpose guiding socket to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-purpose guiding socket to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-purpose guiding socket can be used in cooperation with a guide pin module and is installed on both sides of the connector to play the roles of guiding and current conduction. Guide pin modules are arranged on the left and right sides of the connector, guide pins are arranged on the guide pin modules, and the corresponding ends of the guide pin modules are guiding seats. A guiding cavity is arranged on the guiding seat, and several terminals are arranged on the inner wall of the guiding cavity.

[0007] As a further scheme of the utility model, crimping columns are symmetrically arranged at the lower end of the guiding seat, and screw holes are arranged at the lower end of the guiding seat.

[0008] Specifically, the guiding seat is pre-placed on the PCB board. The crimping columns of the guiding seat and the holes of the PCB board are in interference fit. Force needs to be applied to press the guiding seat into the PCB board. After the crimping is in place, it is fastened through the screw holes with screws.

[0009] As a further scheme of the utility model, second barb structures are symmetrically arranged on the left and right sides of the terminal, and a first barb structure is arranged at the rear side of the second barb structure.

[0010] Specifically, the terminals are elastic terminals and are arranged in an annular and equidistant manner in the guiding cavity. During the process that the guide pins are inserted into the guiding cavity and contact the terminals, the terminals are extruded and deformed, and the elastic force acts on the guide pins in the opposite direction, ensuring the contact stability between the terminals and the guide pins. At the same time, the first barb structure and the second barb structure cooperate with the guiding seat to form two-stage pre-tightening, improving the holding force of the terminals in the guiding seat and the contact reliability between the terminals and the guiding seat.

[0011] As a further solution of the present utility model, the combined use of the guide pin module and the guide seat structure facilitates reducing the large misalignment of the two ends of the connector to the guiding range of the connector, and then smoothly achieving mating through the self-guiding of the connector. After achieving mating, the terminals in the guide seat are in stable contact with the guide pins, and conduction is achieved at both ends, so it can act as a power module for current carrying.

[0012] As a further solution of the present utility model, the guide seat is provided with a hollow structure, and a stabilizing component is provided on the guide seat corresponding to the terminals. The stabilizing component includes a fixing plate, a contact piece, a telescopic rod, and a spring. A fixing plate is provided on the guide seat corresponding to the terminals. A telescopic rod is provided at the lower end of the fixing plate. A contact piece is provided at the lower end of the telescopic rod, and the lower end of the contact piece is in fit with the terminal.

[0013] As a further solution of the present utility model, a spring is sleeved on the telescopic rod. One end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the contact piece.

[0014] Specifically, when the insertion of the guide pin causes the terminal to be squeezed and deformed, through the elastic potential energy of the provided spring, in cooperation with the provided telescopic rod and contact piece structures, it is convenient to improve the stability of the contact between the terminal and the guide pin.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. When the present utility model is in use, the guide seat is pre-placed on the PCB board. The crimping posts of the guide seat are in interference fit with the holes of the PCB board. Force needs to be applied to press the guide seat into the PCB board. After crimping in place, it is tightened through screws in cooperation with the provided screw holes. Then the guide pin is inserted into the guide cavity, the terminal is squeezed and deformed, and the elastic force acts on the guide pin in the opposite direction, ensuring the contact stability between the terminal and the guide pin. At the same time, the first barb structure and the second barb structure cooperate with the guide seat to form two-stage pre-tightening, improving the holding force of the terminal in the guide seat and the contact reliability between the terminal and the guide seat.

[0017] 2. When the present utility model is in use, the guide seat with a hollow structure can prevent sundries from being stuffed into the guide cavity, thereby affecting the contact between the guide pin and the terminal. When the insertion of the guide pin causes the terminal to be squeezed and deformed, through the elastic potential energy of the provided spring, in cooperation with the provided telescopic rod and contact piece structures, it is convenient to improve the stability of the contact between the terminal and the guide pin.

[0018] 3. When the present utility model is in use, through the combined use of the guide pin module and the guide seat structure, it is convenient to reduce the large misalignment at both ends of the connector to the guiding range of the connector, and then through the self-guiding of the connector, the mating can be smoothly achieved. After the mating is achieved, the terminals in the guide seat are in stable contact with the guide pins, and both ends are electrically connected. Thus, it can act as a power module for current carrying. The current enters and exits through the left and right guiding modules, forming a current-carrying loop. This will save a pair of power connectors and the layout space of the PCB board, especially in the case where both guiding function and power transmission are required in a limited space, the advantage is obvious.
