Description

Probe connector 【0001】

The present invention relates to a connector, and more particularly to a probe connector.

【0002】

A conventional probe connector includes a metal sleeve, a probe, and an elastic member. The metal sleeve has a cylindrical hollow receiving tube and a base for closing the bottom end of the receiving tube. The base and the receiving cylinder enclose a receiving space. The probe is movably mounted within the metal sleeve and has a metal sleeve extending from one end. The elastic member is received in the receiving space of the metal sleeve and abuts between the probe and the base.

[0003]

Another conventional probe connector is generally identical in construction to the conventional probe connector described above, except that a metal ball is mounted between the probe and the resilient member. The function is to increase the lateral force of the probe and the metal sleeve to make the contact impedance lower, thereby achieving stable current transmission.

[0004]

However, the two conventional probe connectors have a basic composition of a metal conductor, and a plurality of currents flow through the main path (ie, from the probe along the wall of the metal sleeve to the base of the metal sleeve), a small portion. The current flows through the secondary path (that is, the probe flows through the metal ball and the elastic member to the base of the metal sleeve). Once the probe is separated from the metal sleeve and the current is too large, the elastic member is easily damaged by a large current and burned. , causing product failure.

[0005]

The purpose of this creation is to provide a probe connector that prevents the inrush of a large current and burns the elastic member in view of the drawbacks and deficiencies of the prior art.

[0006]

To achieve the above object, the present probe connector includes a metal sleeve, a probe, an elastic member and an insulating ball. The metal sleeve has a cylindrical hollow-shaped accommodating cylinder. The rear end of the accommodating cylinder is provided with a base for closing the accommodating cylinder. The base and the accommodating cylinder enclose a receiving space, and the front end of the accommodating cylinder contracts inward. An opening is formed in communication with the receiving space, and the diameter of the opening is smaller than the diameter of the inner wall of the receiving space. The probe is slidably mounted in the metal sleeve, and the probe has a cylindrical locking portion. The front end of the locking portion is contracted inwardly and extends forward to form a contact portion. The clamping portion is mounted on the metal. In the receiving space of the sleeve, the contact portion protrudes outwardly from the metal sleeve through the opening of the metal sleeve. The elastic member and the insulating ball are installed in the accommodating space of the metal sleeve. Wherein, one end of the elastic member abuts against the inner wall of the base of the metal sleeve, and the other end of the elastic member abuts against the insulating ball, and the other end of the insulating ball abuts against the rear of the probe end.

【0007】

As described above, the present probe connector is provided with an insulating ball between the probe and the elastic member, which not only increases the lateral contact force between the probe and the metal sleeve, but also prevents the large current caused by the secondary path. Instantly inject and burn the elastic parts to disable them.

To clarify the technical content, structural features, objectives, and effects of the present invention, the embodiments are described in detail below with reference to the drawings.

[0010]

Referring to the second figure, the present probe connector 100 includes a metal sleeve 10, a probe 20, an elastic member 30, and an insulating ball 40.

[0011]

Referring to the first to third figures, the metal sleeve 10 has a cylindrical casing 17 having a hollow structure. A rear end of the accommodating cylinder 11 is provided with a base 12 that closes the accommodating cylinder 11. The base 12 and the accommodating cylinder 11 enclose a receiving space 13 . The front end of the accommodating cylinder 11 is contracted inward to form an opening 14 communicating with the accommodating space 13. The diameter of the opening 14 is smaller than the diameter of the inner wall of the accommodating space 13. The receiving cylinder 11 extends rearwardly from the rear end of the base 12 to form a welded end 15.

[0012]

The probe 20 is slidably mounted in the metal sleeve 10 in a front-rear direction. The probe 20 has a cylindrical holding portion 21. The front end of the catch portion 21 is contracted inward and extends forward to form a contact portion 22. The retaining portion 21 is mounted in the receiving space 13 of the metal sleeve 10, and the contact portion 22 projects outwardly through the opening 14 of the metal sleeve 10 to the metal sleeve 10. In this embodiment, the diameter of the catch portion 21 is larger than the diameter of the opening 14 of the metal sleeve 10, and the diameter of the contact portion 22 is smaller than the diameter of the opening 14 of the metal sleeve 10. Therefore, the holding portion 21 of the probe 20 is clamped behind the opening 14 of the metal sleeve 10, and the contact portion 22 of the probe 20 protrudes from the outside of the metal sleeve 10 to be electrically connected to the external electronic component.

[0013]

The elastic member 30 and the insulating ball 40 are sequentially disposed in the receiving space 13 of the metal sleeve 10 . The diameter of the insulating ball 40 is smaller than the diameter of the inner wall of the receiving space 13 of the metal sleeve 10. One end of the elastic member 30 abuts against the inner wall of the base 12 of the metal sleeve 10, and the other end of the elastic member 30 abuts against the insulating ball 40. The other end of the insulating ball 40 abuts against the rear end of the holding portion 21 of the probe 20. In this embodiment, the elastic member 30 is a spring, and the insulating ball 40 is a plastic ball.

[0014]

Referring to FIG. 1 to FIG. 4 , a second embodiment of the probe connector 100 of the present invention is substantially identical in structure to the first embodiment, except that the insulating ball 40 includes a metal ball 41 and a metal ball. The exterior of the 41 is covered with an insulating varnish 42 to achieve an insulating effect.

[0015]

Referring to the first, second, third and fifth figures, a third embodiment of the probe connector 100 of the present invention is substantially identical in structure to the first embodiment, and the difference is that the insulating ball 40 A metal ball 41 is included, and the outer surface of the metal ball is plated with a nickel underlayer 43, and black nickel 44 is plated on the outside of the nickel underlayer 43 to achieve an insulating effect.

[0016]

As described above, the present probe connector 100 is provided with an insulating ball 40 between the probe 20 and the elastic member 30, which not only increases the lateral contact force between the probe 20 and the metal sleeve 10, but also prevents the secondary contact force. The large current caused by the path is instantaneously poured and the elastic member is burned to make it invalid.
