Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrical components, and in particular to a board end connector, a wiring assembly and a vehicle. BACKGROUND

[0002] A board end connector is a component installed on the edge or surface of a printed circuit board (PCB) to establish mechanical and electrical connections between different circuit boards, modules or external devices. The main function of a board end connector is to achieve stable transmission of signals, power or data, while supporting the modular design and convenient maintenance of devices.

[0003] The board end connector in the prior art generally includes a circuit board, a board end terminal, an interface shell and the like. The board end terminal is generally pressed into a connecting hole in the circuit board by a specific pin machine. However, this connection method has the following defects: (1) the size of the board end terminal is limited by the insertion force of the pin machine; (2) after the board end terminal is inserted into the connecting hole, stress exists at the connection between the board end terminal and the connecting hole, which can easily generate whiskers; (3) the holding force of the board end terminal in the connecting hole is small, and the board end terminal can easily be skewed; and (4) a specific pin machine is required for the connection process, which requires high precision of the pin machine and results in high processing cost.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0005] To solve or improve to some extent the technical problems of poor quality and high processing cost of the board end connector in the prior art, the utility model provides a board end connector. The board end connector comprises an interface shell, a circuit board and a board end terminal. The interface shell is adapted to be plugged with a wire end connector, and a through hole is formed in the interface shell. The circuit board is connected with the interface shell, and a plurality of connecting holes are formed in the circuit board and spaced apart from each other. The board end terminal comprises a plurality of pins and a pin. Each pin is inserted into and welded in the corresponding connecting hole, and the pin extends through the through hole and is adapted to form an electrical connection with a wire end terminal in the wire end connector.

Among them, interface shell is configured to be inserted with wire end connector, so that board end connector and wire end connector can be conveniently and stably connected. Circuit board is connected with interface shell, so that board end connector has stable and compact structure. A plurality of connecting holes are arranged on circuit board and spaced apart from each other, and a plurality of pins of board end terminal are respectively inserted and welded in corresponding connecting holes. In this way, not only can the stress between board end terminal and connecting hole be eliminated, the holding force of board end terminal and connecting hole can be improved, whisker and skew needle can be avoided, but also special pin equipment is not needed, so that the processing cost is reduced. In addition, a through hole is formed on interface shell, and the pin of board end terminal extends through the through hole, so that the pin can be conveniently electrically connected with the wire end terminal in the wire end connector. Therefore, the utility model embeds the pin on the board end terminal into the through hole on the interface shell instead of being directly fixed on the interface shell, so that not only the model and specification of the board end terminal can be flexibly adjusted, but also the board end terminal can be conveniently maintained.

[0007] In the preferred technical scheme of the above-mentioned board end connector, the board end terminal further comprises a base having a first side and a second side opposite to each other along the height direction of the base, wherein the pin is arranged on the first side, and a plurality of the pins are arranged on the second side spaced apart from each other.

The arrangement of the positioning hole and the positioning column can make the board end terminal be quickly and accurately connected with the circuit board.

[0009] In the preferred technical scheme of the above-mentioned board end connector, the pins are connected with the connecting holes through a tin soldering process. The tin soldering process has the advantages of firm soldering point, simple and flexible process, low cost, high efficiency, easy maintenance and high quality controllability.

The arrangement of the insertion slot can not only enhance the connection efficiency and convenience between the interface shell and the wire end connector, but also enhance the mechanical stability and improve the protection ability.

[0011] In the preferred technical scheme of the above-mentioned board end connector, a first clamping jaw adapted to form clamping cooperation with a first clamping hole on the wire end connector is arranged in the insertion slot. The arrangement of the first clamping hole and the first clamping jaw can make the interface shell and the wire end connector form clamping cooperation conveniently.

The arrangement of the annular wall can further enhance the protection capability of the interface shell on the wire end connector inserted in the insertion slot. In addition, the arrangement of the second clamping hole and the second clamping claw can further improve the reliability of the clamping connection between the interface shell and the wire end connector.

[0013] In the preferred technical scheme of the board end connector, a protection gasket is arranged in the insertion slot. The arrangement of the protection gasket can effectively isolate water vapor, dust and other foreign matters, so as to avoid damage to the circuit board.

[0014] In the preferred technical scheme of the board end connector, a limiting protrusion vertically extending outward and abutting against the circuit board is formed on the interface shell. The arrangement of the limiting protrusion can separate a suitable gap between the interface shell and the circuit board, so as to avoid damage to the circuit board caused by the direct abutment of the interface shell on the circuit board.

The wiring assembly comprises a wire end connector and the board end connector in any one of the above, wherein the wire end connector is configured to be inserted on the board end connector to form an electrical connection.

[0049] Continuing to refer to Figure 8In one or more embodiments, four positioning posts 134 are further arranged on the second side 1312 of the base 131 and are spaced apart from each other. Figure 4 As shown in the orientation, two positioning posts 134 are located on the front side of the pin 132, and the other two positioning posts 134 are located on the rear side of the pin 132. Each positioning post 134 has a substantially cylindrical shape. In the assembled state, each positioning post 134 can be inserted into the corresponding positioning hole 123 on the circuit board 12.

[0050] In one or more embodiments, the utility model further provides a vehicle (not shown in the figure). The vehicle comprises at least one wiring assembly 1 described above.

[0051] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
