Description

C-shaped buckle and female connector using this C-shaped buckle

The present invention relates to a C-shaped buckle for a female connector, and more particularly to an improved structure of a C-shaped buckle, which can provide elastic recovery force of the female connector, thereby providing the service life of the female connector.

The design of the traditional female connector is such that when the male terminal is inserted and removed for a long time and multiple times, the conductive elastic piece inside the female connector may be excessively expanded by the male terminal to cause inelastic deformation, resulting in the subsequent female end. Poor contact between the connector and the male terminal, resulting in an increase in resistance. In order to reduce the above problem, some female connector connectors are designed to be sleeved with a C-shaped buckle on the conductive elastic piece, and the conductive elastic piece is biased through the C-shaped buckle to maintain the elasticity of the conductive elastic piece and maintain the connection between the male terminal and the female end. Good contact relationship.

There is a conventional C-shaped buckle structure. Referring to the three-dimensional partial cross-sectional view of the C-shaped buckle 70 of FIG. 1, it can be seen that the conventional C-shaped buckle 70 is roughly bent by a flat plate to form a hollow circular ring. And the cross section of the C-shaped buckle 70 in the direction of the axis A is a rectangle. However, the conventional C-shaped buckle 70 is used to cover the conductive elastic piece in a surface contact manner, and the C-shaped buckle 70 itself is insufficiently elastic, so that after the female connector is repeatedly inserted and removed, the conductive elastic piece may still be excessively deformed. Subsequent contact between the male and female connectors reduces the durability of the female connector.

In view of this, one of the aims of this creation is to provide a brand new C-shaped buckle that can make full use of the shell structure to provide more elastic resilience.

In order to achieve the above object, the present invention provides a C-shaped buckle that is sleeved on a conductive elastic piece of a female end connector and is disposed in a casing of the female end connector together with a conductive elastic piece. Wherein, the C-shaped buckle is substantially annular and surrounds the virtual one-axis center, and the cross-section of the C-shaped buckle along the axial direction has an opposite inner side and an outer side, and the inner side and the outer side are both It is an arc with an opening facing the axis. Therefore, the C-shaped buckle can be elastically deformed by force, and the two ends of the inner side abut against the conductive elastic piece and the center of the outer side abuts against the inner wall surface of the casing.

The present invention further provides a female connector comprising a housing, a conductive elastic piece and a C-shaped buckle. Wherein, the conductive elastic piece is substantially annular and is accommodated in the casing. The C-shaped buckle is a circular ring that surrounds the virtual one and is coaxially sleeved with the conductive elastic piece. The cross section of the C-shaped buckle along the axial direction has an opposite inner side and an outer side, and the inner side and the outer side are arcs having an opening toward the axis, and the C-shaped buckle can be stressed. Elastically deformed, the two ends of the inner side abut against the conductive elastic piece and the center of the outer side abuts against the inner wall surface of the casing.

Through the structure of the C-shaped buckle of the present invention, the C-shaped buckle can be elastically deformed not only from the outside to the inside, but also elastically deformed in the axial direction, so that the female connector overall has more elastic restoring force, and can withstand the male terminal. Multiple plugging and unplugging to increase the life of the female connector.

In order to better understand the characteristics of the present female connector 1, the present invention provides a preferred embodiment and is described below with reference to the drawings. Please refer to FIG. 3 first. The main components of the female connector 1 include a housing 10, and a conductive elastic piece 20 and a C-shaped buckle 30 housed in the housing 10. The structure of each component and the relationship between them are as follows:

Referring to FIG. 3, the conductive elastic piece 20 is a hollow cylinder having a bottom edge 24 and four slits 24 to form four conductive portions 22. The outer peripheral surface 21 of each of the conductive portions 22 is provided with a recess 28 which is arranged in a ring direction and is equally spaced from the bottom edge 24.

Please refer to Figures 2 to 4 together. The C-shaped buckle 30 is a groove 28 that is coaxially sleeved on the conductive elastic piece 20. The C-shaped buckle 30 is in the shape of an annular cylinder and surrounds a virtual axis A. The cross section of the C-shaped buckle 30 in the direction of the axis A has an inner side 32 and an outer side 34, and the inner side 32 and the outer side. The side edges 34 are all circular arcs having an opening toward the axis A and have the same radius of curvature. When the C-shaped buckle 30 is sleeved on the recess 28 of the conductive elastic piece 20 and received in the interior of the housing 10, as shown in FIGS. 4 to 6, the opposite end edges 322 of the inner side 32 abut each groove. 28 is at the two ends of the axis A direction, and an intermediate point 324 of the inner side 32 does not contact the bottom surface of the groove 28, and the distance h1 of each end edge 322 to the axis A is equidistant. In addition, an intermediate point 344 of the outer side 34 of the C-shaped buckle 30 abuts against the inner wall surface 12 of the casing 10, but the opposite end edges 342 of the outer side 34 do not abut the inner wall surface 12 of the casing 10, and each The distance h2 from the end edge 342 to the axis A is equidistant. In other words, the distance h1 from the end edge 322 of the inner side 32 to the axis A is less than the distance H1 from the intermediate point 324 of the inner side 32 to the axis A, and the outer side 34 The distance h2 from the end edge 342 to the axis A is a distance H2 from the intermediate point 342 of the outer side 34 to the axis A.

Referring to FIG. 5 and FIG. 6 , when the male terminal 5 is inserted into the female connector 1 of the embodiment, the C-shaped buckle 30 of the present embodiment has only the two end edges 322 of the inner side 32 abutting the conductive elastic piece. 20, and the intermediate point 344 of the outer side 34 abuts against the inner wall surface 12 of the casing 10. Through the improved structure of the C-shaped buckle 30, the C-shaped buckle 30 can simultaneously have a space for elastically deforming from the outside to the inside and at the axial center. The space in the A direction is elastically deformed, and the C-shaped buckle 30 abuts the housing 10 and the conductive elastic piece 20 in a line contact manner. Therefore, when the conductive elastic piece 20 is stretched by the action of the male terminal 5, the C-shaped buckle 30 has an outer side edge 34 which abuts against the inner wall of the casing 10 and causes the inner side in addition to the elasticity provided by the original material elasticity. The two end edges 322 of the side 32 are elastically deformed outward (that is, the radius of curvature of the inner side edge 32 and the outer side edge 34 is increased), and an elastic restoring force is applied to the conductive elastic piece 20 to suppress the possibility of excessive deformation of the conductive elastic piece 20. To withstand the insertion and removal of the male terminal 5 more times, thereby increasing the service life of the female connector 1.

Finally, it must be stated that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Other equivalent structural changes should also be made in the scope of the patent application of the present application. Covered.
