Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a quick positioning connector. Background Art

[0002] Connectors are a component that electronic engineers often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve the intended function. Therefore, the application range of connectors is also very wide. Among them, wire-to-board connectors are also widely used because they can connect power lines to PCB boards.

[0003] A wire-to-board connector generally includes a housing and a PIN inserted in the housing. One end of the PIN is connected to the power line, and the other end is soldered to the PCB board, thereby achieving electrical connection between the power line and the PCB board. However, when installing a conventional wire-to-board connector, since the connector, the power line, and the PCB board are usually formed separately before being assembled, and the PIN is relatively soft as a whole and easily deformed, it is easy to cause welding dislocation due to deformation when the PIN is connected to the PCB board, resulting in poor connection. The PIN needs to be manually adjusted, which is time-consuming and labor-intensive, and reduces work efficiency.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

[0005] The utility model aims to provide a quick positioning connector which can be positioned accurately and more quickly when connected to a PCB board.

[0008] Preferably, a plurality of limiting parts are provided outside the shell, the number of the PIN needles is n, the number of the limiting parts is n+1, and the limiting parts are arranged at equal intervals, and the PIN needle passes between two adjacent limiting parts.

[0009] Preferably, the position of the PIN pinhole corresponds to the spatial position between two adjacent limiting portions, and the distance between adjacent limiting portions does not exceed the diameter of the PIN pinhole.

[0010] Preferably, a plurality of outwardly protruding reinforcing ribs are provided on the circumference of the positioning column to facilitate the engagement and fixation of the positioning column with the positioning hole.

[0011] Preferably, anti-slip grooves are provided on both sides of one end of the housing connected to the power cord, and a connecting end of the power cord and the connector is provided with a thorn adapted to the anti-slip groove.

[0012] Preferably, at least one boss is provided inside the shell near the connection end with the power cord, and the connection end between the shell and the power cord is arranged in an asymmetrical shape to form an anti-foolproof portion.

[0013] Preferably, a plurality of material escape grooves are provided on the connection surface between the bottom of the shell and the PCB board.

[0014] The utility model provides a quick positioning connector with the following beneficial effects:

[0015] The quick positioning connector of the utility model cooperates with the positioning post on the housing and the positioning hole on the PCB, so that the housing can be installed at the designated position on the PCB more quickly.

[0025] Example

[0026] See also Figures 1 to 5 A quick positioning connector, used to connect a power cord and a PCB board 3, comprises a housing 1 and a plurality of PIN pins 2, the PCB board is located outside the bottom of the housing, and the power cord is connected to the inside of the housing; a mounting hole 11 is provided on the housing, one end of the PIN pin is located inside the housing and is arranged parallel to the PCB board for connection with the power cord, and the other end extends out of the housing from the mounting hole and points to the PCB board for connection and fixation with the PCB board; at least one pair of positioning posts 12 are fixedly provided at the bottom of the housing 1, the positioning posts are located on both sides of the PIN pin, a positioning hole 31 adapted to the positioning post and a PIN pin hole 32 adapted to the end of the PIN pin are provided on the PCB board, and the spacing of the PIN pin hole relative to the positioning hole is adapted to the spacing of the mounting hole relative to the positioning post.

[0027] The housing 1 is provided with a plurality of limiting parts 13 on the outside. The number of the PIN pins is n, and the number of the limiting parts is n+1. Preferably, the number of the PIN pins is 8, and the number of the limiting parts is 9. The limiting parts are arranged at equal intervals, and the PIN pin passes through two adjacent limiting parts. The limiting parts are wavy or sawtooth-shaped as a whole to ensure that the limiting space formed between adjacent limiting parts is open away from one side of the housing. This structure is more convenient for the installation of the PIN pin while limiting.

[0028] The position of the PIN pin hole 32 corresponds to the spatial position between two adjacent limiting parts, and the spacing between adjacent limiting parts does not exceed the diameter of the PIN pin hole. The spacing between adjacent limiting parts is not less than the width of the PIN pin, and the position of the PIN pin is limited by the limiting part when passing through the adjacent limiting part so that the PIN pin is aligned with the PIN pin hole.

[0029] The circumference of the positioning column 12 is provided with a plurality of outwardly protruding reinforcing ribs to facilitate the engagement and fixing of the positioning column with the positioning hole. There are gaps between the reinforcing ribs, and the outer diameter of the positioning column including the reinforcing ribs is not less than the diameter of the positioning hole. Preferably, the outer diameter of the positioning column including the reinforcing ribs is greater than the diameter of the positioning hole to facilitate an interference fit. However, in order to ensure convenient insertion and removal, the contact area can be reduced by the contact between the reinforcing ribs and the positioning hole. At the same time, an inverted cone structure is provided at the bottom of the positioning column, which makes it easier and more convenient to insert the positioning column into the positioning hole during installation.

[0030] The housing 1 is provided with anti-slip grooves 14 on both sides of one end connected to the power line, and the connecting end of the power line and the connector is provided with thorns adapted to the anti-slip grooves.

[0031] At least one boss is disposed inside the housing 1 near the connection end with the power line, and the connection end with the power line inside the housing is arranged in an asymmetrical shape to form an anti-foolproof portion 15 .

[0032] The bottom of the housing 1 and the connection surface of the PCB board are provided with a plurality of escape grooves 16, preferably two, which are connected to the inside of the housing and matched with the position of the boss. The escape grooves can assist the positioning column in rapid positioning and prevent the connector housing from deformation.

[0033] The beneficial effects of the utility model are as follows: the positioning post on the shell cooperates with the positioning hole on the PCB, so that the shell can be installed at the specified position on the PCB more quickly, and at the same time, the limiting part and the PIN pin hole are set based on the positioning post and the positioning hole, and the PIN pin is pre-positioned by the limiting part, so as to reduce the bending and dislocation of the PIN pin before installation, and can also be quickly matched with the PIN pin hole during installation, thereby greatly improving the installation efficiency of the connector and the PCB board, and under the guidance of the positioning post and the limiting part, the installation accuracy is also higher.
