Other objects and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

In order to achieve the purpose, the utility model adopts the following technical scheme: a contact terminal of a spring pin connector is in a short cylinder shape and is provided with an arc-shaped head part positioned at one end of the contact terminal and a positioning column positioned at the other end of the contact terminal, a neck part is also formed between the head part and the positioning column, and a circle of dentate projections are respectively formed on the cylindrical surfaces at two sides of the neck part; wherein the diameter of the neck portion is smaller than the diameter of the circumference on which the tooth-like protrusions are located.

In one embodiment, the contact terminal comprises a first section with the largest diameter at one end of the contact terminal, a second section in the middle of the contact terminal, and a third section with the smallest diameter at the other end of the contact terminal; the head is located at the first section, the positioning column is located at the third section, and the neck and the dentate protuberance are located at the second section.

In one embodiment, a shoulder is also formed between the first and second sections of the contact terminal.

In one embodiment, the diameter of the head is the largest and the diameter of the post is the smallest.

In one embodiment, the positioning post has a tip.

Compared with the prior art, the utility model discloses spring pin connector's contact terminal can with the neck structure of sleeve pipe buckle through the setting to and can form interference fit's cusp with the sleeve pipe and protruding, thereby form the fixed knot structure of dual fail-safe, ensure that the cooperation is inseparable between this contact terminal and this sleeve pipe, can be more reliable with external electric contact with guaranteeing this contact terminal, the phenomenon of skew about can not taking place.

Detailed Description

The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc. refer to directions of the attached drawings only. Accordingly, the directional terms used are used for describing and understanding the present invention, and are not used for limiting the present invention.

Referring to fig. 1 and 2, a contact terminal 20 of the pogo pin connector of the present invention is generally in the shape of a short cylinder, and has an arc-shaped head 21 at one end and a positioning post 22 at the other end, a neck 23 is formed between the head 21 and the positioning post 22, and a circle of tooth-shaped protrusions 24 are respectively formed on the cylindrical surfaces of the two sides of the neck 23. Wherein the diameter of the head 21 is the largest and the diameter of the positioning post 22 is the smallest. The diameter of the neck 23 is smaller than the diameter of the circumference on which the tooth-like projections 24 are located.

More specifically, the contact terminal 20 is roughly divided into three sections with different diameters, including a first section 201 with the largest diameter at one end of the contact terminal 20, a second section 202 with a smaller diameter at the middle of the contact terminal 20, and a third section 203 with the smallest diameter at the other end of the contact terminal 20. The head 21 is located at the first section 201, the positioning column 22 is located at the third section 203, and the neck 23 and the tooth-like protrusions 24 are located at the second section 202.

In addition, a shoulder 25 is formed between the first section 201 and the second section 202 of the contact terminal 20.

As shown in fig. 3, the contact terminal 20 is mounted on one end of the sleeve 10 of the pogo pin connector, wherein the second section 202 and the third section 203 of the contact terminal 20 both extend into the sleeve 10, and the first section 201 is exposed outside the sleeve 10. Specifically, the head portion 21 of the contact terminal 20 is exposed outside the bushing 10 to be electrically contacted with an external device (not shown). Specifically, the positioning post 22, the neck portion 23, and the tooth-shaped protrusion 24 of the contact terminal 20 all enter the sleeve 10, the first inner convex hull 12 formed on the sleeve 10 is clamped into the neck portion 23, and the tooth-shaped protrusion 24 forms an interference fit with the inner wall of the sleeve 10, which can ensure a tight fit between the contact terminal 20 and the sleeve 10, so as to ensure that the contact terminal 20 can be electrically contacted with the outside more reliably, and the left and right offset phenomenon does not occur. In addition, the shoulder 25 can limit the length of the contact terminal 20 protruding into the sleeve 10, preventing the contact terminal 20 from being over-inserted into the sleeve 10, ensuring that the head 21 of the contact terminal 20 is exposed to the outside.

In the present embodiment, the positioning post 22 has a tip to facilitate the fixation with the spring in the pogo pin connector.

To sum up, the utility model discloses contact terminal 20 of spring pin connector still sets up the dentate that can form interference fit 24 with sleeve pipe 10 through setting up the neck 23 structure that can buckle with sleeve pipe 10 to form the fixed knot structure of dual fail-safe, ensure that the cooperation is inseparable between this contact terminal 20 and this sleeve pipe 10, in order to guarantee that this contact terminal 20 can be more reliable with external electrical contact, can not take place the phenomenon of controlling the skew.
