Problems solved by technology

In the case of the same contact material (that is, the same resistivity ρ), although this kind of contact can ensure that its conductive area A is improved, but the conductive distance L from the waist to the two ends is extended, it is bound to be Will increase the contact resistance R of the contact
And in order to ensure that the waist has good elasticity, the second type of contact must be made relatively long. Therefore, it is difficult to adapt to the insertion of short plugs, and at the same time it consumes more materials.

Embodiment 1

[0038] Example 1: Please refer to figure 1 with figure 2 , a contact piece 10, including a metal cylinder 11 and a plurality of bent elastic pieces 12.

[0039] A slit 111 is defined in the axial direction of the metal cylinder 11 . When the outer wall of the metal cylinder 11 is squeezed, the width of the gap 111 changes accordingly, thereby fine-tuning the diameter of the metal cylinder 11 . Therefore, it is possible to make the metal cylinder 11 enter into a slightly narrow space, and then expand the gap 111 through its own recovery ability, and at this time, the metal cylinder 11 can block the limit end of the slightly narrow space.

[0040] Both ends of the metal cylinder 11 are respectively provided with a plurality of separated bending elastic pieces 12 , and the bending direction of the bending elastic pieces 12 is bent from the center of the metal cylinder 11 to the outer wall of the metal cylinder 11 .

[0041] When the external pin is inserted, the pin touches t...

Embodiment 2

[0046] Example 2: Please refer to Figure 4-Figure 6 , On the basis of the first embodiment, this technical solution also provides a socket structure, including the socket 20 and the contact piece 10 disclosed in the first embodiment.

[0047] One end of the socket 20 is provided with a receiving groove 21 , and at least one first annular groove 22 is defined on the groove wall of the receiving groove 21 . Through the above method of compressing the gap 111 , the contact piece 10 is squeezed into the first annular groove 22 with a slight inclination.

[0048] Since the distance from the metal cylinder 11 to the second bent portion 124 in this embodiment is greater than the depth of the first annular groove 22 , the axial length of the contact member 10 is greater than the width of the first annular groove 22 . Therefore, when the second bent portion 124 is in contact with the bottom of the first annular groove 22, the second end portion 122 touches the notch of the first annu...

Embodiment 3

[0051] Example 3: Please refer to Figure 10-Figure 12 , On the basis of the first embodiment, the present technical solution also provides a composite socket structure, including the socket 40, the rotating spring 50, a plurality of hollow glands 60 and the contact piece 10 disclosed in the first embodiment.

[0052] In this embodiment, the diameter of both ends of the rotating spring 50 is larger, and the diameter of the middle part is smaller. The middle part of the inner wall of the hole sleeve 40 is provided with a second annular groove 41 .

[0053] The contact piece 10 is sheathed in the middle of the rotating spring 50 , and both of them are set in the hole sleeve 40 . The contact piece 10 is correspondingly snapped into the second annular groove 41 . The hollow pressing cover 60 presses the end of the rotary spring 50 and the end of the hole sleeve 40 together.

[0054] The installation method of this composite grommet 40 is as follows:

[0055] First, the gap 111 ...

Abstract

The invention discloses a contact member. The contact member includes a metal cylinder; the metal cylinder is provided with a slit in the axial direction; two ends of the metal cylinder are respectively provided with a plurality of bending shrapnel pieces separated from each other; and bending directions of the bending shrapnel pieces bend toward the direction of the outer wall of the metal cylinder from the center of the metal cylinder. The invention provides the contact member with short structure and excellent conductive effect.

Description

technical field [0001] The invention relates to the technical field of contacts, in particular to a contact, a socket structure and a composite hole structure. Background technique [0002] With the rapid development of electronic products, the spare parts related to electronic products have also developed rapidly, especially the contacts of electrical connectors. [0003] Contacts of existing electrical connectors are mainly divided into two categories: the first category adopts a shrapnel structure. The main factors that affect the contact resistance R (Ω) of the contact itself are: a. The effective conductive distance L (m) of the conductor, b. The resistivity of the conductor ρ (Ω·mm 2 / m), c. The effective conductive cross-sectional area of ​​the conductor A (mm 2 ). [0004] Its principle expression is: [0005] When the material of the contact is the same (that is, the resistivity ρ is the same) and the length L of the contact is the same, the factor that affect...
