However, when the above-mentioned probe connector 1' is subjected to vibration, the electrical conduction between the metal probe 20' and the metal sleeve 10' is prone to instantaneous disconnection; the metal probe 20' and the metal sleeve 10' are electrically When the conduction is broken, the elastic body 30 ′ will generate high temperature due to its high impedance characteristic, thereby affecting the electrical conduction performance of the probe connector 1 ′.

Utility model content

The main purpose of this utility model is to provide a probe connector for the defects of the above-mentioned prior art. The metal probe of the probe connector is in stable contact with the metal sleeve, so that the electrical connection of the probe connector is stable. Sexual connection is reliable.

To achieve the above purpose, the probe connector provided by the utility model includes a metal sleeve, a metal probe, a first elastic body and a second elastic body. The metal sleeve has a shell, the bottom of the shell is connected with a base, the top of the shell is bent and extended inward to form a stopper, and the stopper has an opening. The metal probe has a sliding part and a contact part protruding upward from the sliding part. The sliding part is installed in the shell of the metal sleeve, and the contact part protrudes out of the metal sleeve from the opening. The first elastic body is accommodated in the shell of the metal sleeve, one end of which is against the bottom surface of the sliding part, and the other end is against the base. The second elastic body is fixed on the casing, and the second elastic body has an abutting portion extending into the casing through the side hole of the casing and abutting against the side surface of the sliding part.

When the metal probe of the utility model is pressed into the metal sleeve, since the abutting portion of the second elastic body acts on the sliding part of the metal probe from the side, the sliding part of the metal probe can be more stably contacted. On the inner wall of the metal sleeve, so that the electrical connection of the probe connector is reliable.

Detailed ways

In order to describe the technical content, structural features and the purpose and effect achieved by the utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 and FIG. 2 , the probe connector 1 of the present invention has a metal sleeve 10 , a metal probe 20 , a first elastic body 30 and a second elastic body 40 .

The metal sleeve 10 has a cylindrical housing 11, the bottom of the housing 11 is connected with a closed base 12, and one end of the housing 11 is bent inward to form a circular stopper 13, the stopper 13 There is an opening 14 , a stabilizing groove 121 is formed on the edge of the surface of the base 12 , and a limiting groove 122 communicating with the stabilizing groove 121 is defined upward along the surface of the base 12 .

The metal probe 20 has a cylindrical sliding portion 22 and a cylindrical contact portion 21 protruding upward from the sliding portion 22 . The sliding part 22 is installed in the housing 11 of the metal sleeve 10, the bottom surface of the sliding part 22 is an inclined surface, and the diameter of the sliding part 22 is larger than the diameter of the opening 14 so that the sliding part 22 is clamped in the housing 11; The diameter of the contact portion 21 is smaller than the diameter of the opening 15 , and the contact portion 21 protrudes out of the metal sleeve 10 through the opening 14 of the metal sleeve 10 , so that the contact portion 21 can be electrically connected with an external electronic component.

The first elastic body 30 is accommodated in the casing 11 of the metal sleeve 10 , one end thereof abuts against the bottom surface of the sliding portion 22 , and the other end abuts against the base 12 .

The second elastic body 40 is fixed on the housing 11, and the second elastic body 40 has a substantially annular stabilizing ring 42, and the stabilizing ring 42 is fitted under the stabilizing groove 121 of the base 12 from the top of the metal sleeve 10. Inside. An elastic arm portion 43 is bent and extended from the stabilizing ring 42 . The elastic arm portion 43 is accommodated in the limiting groove 122 . 111 protrudes into the housing 11 , and the abutting portion 41 can abut against a side surface of the sliding portion 22 .

Please continue to refer to Fig. 1 and Fig. 2. When assembling the probe connector 1, first install the metal probe 20 from the top of the housing 11, and then press the upper end of the housing 11 inward to form the ring. Shaped stopper 13.

Please refer to FIG. 3 , when the probe connector 1 is in use, the metal probe 20 is moved downward by an external force, the metal probe 20 compresses the elastic body 30 downward, and the sliding part 22 slides downward along the inner wall of the housing 11 .
