High-vibration connector torsion reed and manufacturing method thereof

Abstract

The invention discloses a high-vibration connector torsion spring which comprises an integrally-formed metal tubular body, the metal tubular body comprises a positioning strip, a bus bar, at least two C-shaped pipe strips and a fixing pressing ring used for being riveted with a jack body, the two ends of the bus bar are fixedly connected with the C-shaped pipe strips respectively, and the C-shaped pipe strips are fixedly connected with the bus bar. The positioning strips are distributed on the end face of the C-shaped pipe strip in an annular array mode, and the metal tubular body is in a rotary waisted spiral shape. The bus bar type connector is used for being installed in a connector and has the alignment and shunting functions, the bus bar extends on the C-shaped tubular body, alignment assembly can be conducted through the bus bar when the bus bar type connector is assembled, the central axis of the bus bar type connector coincides with the central axis of the connector, and therefore the connector can be assembled conveniently. The bus bar can also increase the contact area between the connecting plug and the connecting piece so as to conduct current in time; the bus bar has a function of not moving in a high-frequency vibration environment, and separation of the bus bar and the connecting plug and reduction of a contact area between the bus bar and the connecting plug are prevented.

Description

technical field [0001] The invention relates to the related technical field of jack contacts, in particular to a high-vibration connector torsion spring and a manufacturing method thereof. Background technique [0002] With the rapid development of high-voltage and high-current electrical connectors, most of the torsion spring jacks used in the industry today are helical simple cylinders, and both ends are open and freely assembled into the jack body. Since the free quiver is a sheet metal stamping roll It is twisted afterward, resulting in the poor roundness of the spiral cylinder and the poor parallelism of the two end faces. As a result, the vehicle cannot be limited in the axial direction and has good contact and shunting in the high-speed vibration environment, so that the vehicle is prone to ablation when running at high speed. , once ablation occurs, it will bring great hidden danger to safety; [0003] For example, a new type of socket contact piece disclosed in Pat...

Problems solved by technology

[0002] With the rapid development of high-voltage and high-current electrical connectors, most of the torsion spring jacks used in the industry today are spiral-shaped simple barrels, and the two ends are open and freely assembled into the jack body. Since the free quiver is a sheet metal stamping roll After being twisted, the circularity of the spiral tube is poor and the parallelism of the two ends is poor, so that the vehicle cannot be limited in the axial direction and has good contact and shunt in the high-speed vibration environment, so that the vehicle is prone to ablation when running at high speed , once ablation occurs, it will bring great hidden danger to safety;

[0003] For example, the patent No. CN102157820B discloses a new type of socket contact piece. In order to prevent shaking and poor contact, the length of the connector plugged into the connector needs to be greater than the length of the torsion reed, and the torsion reed can be pressed tightly on the The position between the connector and the connector is relatively stable, but in actual use, the length of the connector is not necessarily greater than the length of the torsion spring. In the high-frequency vibration environment, the use of this contact is prone to axial displacement. The phenomenon of poor contact, difficulty in shunting, and ablation due to movement. In order to solve the above problems, further improvement is needed
