Referring to fig. 3 and 4, the single-pin pogpin connector of the present embodiment mainly comprises a pin shaft 10, a needle tube 20, a spring 30, a rubber core 40, an assembly post 50, a buckle 60, and the like.

Wherein needle cannula 20 may be designed as a hollow cylinder structure with the hollow portion forming an interior cavity 21 for receiving needle shaft 10 and spring 30. An opening 22 is formed in the top surface of the needle cannula 20. Preferably, the opening 22 is designed as a round opening and has a diameter smaller than the diameter of the needle cannula 20. Thus, the top surface of the needle tube 20 is folded over the opening 22 to form a neck 23. The bottom surface of the needle cannula 20 may form a bonding pad 24 for soldering to a circuit board.

The needle shaft 10 can be designed into an upper part and a lower part, the lower part 12 can be designed into a cylinder shape and is internally arranged in the inner cavity 21 of the needle tube 20, and the lower part 12 of the needle shaft 10 is limited in the inner cavity 21 of the needle tube 20 by the neck 23 of the needle tube 20. The upper half 11 of the needle shaft 10 may be designed in a cylindrical shape with a smaller diameter than the lower half 12. The upper half 11 of the needle shaft 10 extends from the opening 22 of the needle cannula 20 to the top surface of the needle cannula 20 for contact conduction with other conductive members for transmitting electrical signals.

The spring 30 is arranged in the inner cavity 21 of the needle tube 20, the upper end is connected with the bottom surface of the lower half part 12 of the needle shaft 10, and the lower end is connected with the bottom surface of the inner cavity 21 of the needle tube 20. By compressing spring 30 with needle shaft 10, upper portion 11 of needle shaft 10 may be retracted within interior cavity 21 of needle cannula 20. When the external force on the needle shaft 10 is removed, the needle shaft 10 ejects the upper half 11 thereof out of the inner cavity 21 of the needle tube 20 under the elastic restoring force of the spring 30.

The rubber core 40 is wrapped around the outer periphery of the needle tube 20, the top of the needle tube 20 exposes the top surface of the rubber core 40, and the bonding pad 24 at the bottom of the needle tube 20 exposes the bottom surface of the rubber core 40.

The two sides defining the relative positional relationship of the glue core 40 are a first side 41 and a second side 42, respectively, for example, the left side of the glue core 40 is defined as the first side 41 and the right side of the glue core 40 is defined as the second side 42. The mounting post 50 is mounted on the first side 41 of the core 40 and the clip 60 is mounted on the second side 42 of the core 40.

In this embodiment, the shape of the mounting post 50 should be adapted to the shape of the catch 60, i.e. the shape of the catch 60 should be adapted to the shape of at least part of the outer contour of the mounting post 50. For example, the fitting post 50 may be designed in a cylindrical shape, and the clip 60 may be designed in a semicircular arc shape and have elasticity, as shown in fig. 3. The radius of the intrados of the semicircular arc-shaped buckle 60 is designed to be equal to or slightly smaller than the radius of the cylinder of the assembly post 50, so as to ensure the firmness of the assembly between the assembly post 50 and the buckle 60.

In some embodiments, the mounting post 50 may be made of a resilient material, such as plastic, to further simplify the assembly of the mounting post 50 with the clip 60.

In order to enable the two single-pin pogpin connectors to adjust the angle between the two connectors after being clamped, the cylindrical assembly column 50 is vertically installed on the first side 41 of the rubber core 40, namely, the axial direction of the cylindrical assembly column 50 is parallel to the axial direction of the needle shaft 10, so that when the assembly column 50 is clamped in the buckle 60, the assembly column 50 can rotate in the buckle 60, and the aim of adjusting the angle between the two adjacent single-pin pogpin connectors is achieved.

Specifically, as shown in fig. 5, when a plurality of single-pin pogpin connectors as shown in fig. 3 are assembled together to form a multi-pin pogpin connector assembly, the clip 160 of the first single-pin pogpin connector 100 may be assembled with the assembly post 250 of the second single-pin pogpin connector 200 (single-pin pogpin connectors located at intermediate positions, with single-pin pogpin connectors located at front and rear). At the same time, the clip 260 of the second single pin pogpin connector 200 is snapped together with the mounting post 350 of the third single pin pogpin connector 300, and so on. The corresponding number of single-pin pogpin connectors can be selected to be assembled together according to the number of pins required by a user so as to form the multi-pin pogpin connector.

When the connectors are arranged on the circuit board, according to the reserved positions of the circuit board, the multi-pin pogon connectors may not be arranged in an in-line mode, at this time, the angle between the single-pin pogon connectors can be adjusted, and the overall shape of the multi-pin pogon connectors is changed, as shown in fig. 6, so as to meet the arrangement requirements on the circuit board.

In this embodiment, the rubber core 40 may be designed into various shapes such as a rectangular parallelepiped structure and a cylindrical structure, and in order to increase the rotation angle range between two adjacent single-needle pogpin connectors as much as possible, the rubber core 40 is preferably designed into a cylindrical structure.

The pogpin connector assembly of the embodiment is formed by plugging a plurality of independent single-pin pogpin connectors, compared with the traditional inseparable multi-pin pogpin connectors, the number of pins of the connectors can be freely configured, the overall shape of the connectors can be freely changed, and the connector is more flexible and changeable to use.

Of course, the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
