Embodiment Construction
[0016] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] A specific embodiment 1 of an electrical connector of the present invention, such as Figure 1 to Figure 3 As shown, it includes a contact spring installation structure for installing the contact spring. The contact spring installation structure includes a closed annular groove 2 arranged on the outer peripheral surface of the cylindrical housing 1. The section of the annular groove 2 is a dovetail groove. Shaped, a contact spring 3 is installed in the annular groove 2, and in this embodiment, the contact spring is a ground spring. The axial dimension of the notch of the annular groove 2 is smaller than the axial dimension of the contact spring 3, the maximum axial dimension of the annular groove 2 is greater than or equal to the axial dimension of the contact spring 3, the contact spring is installed in the annular groove and is ring-shaped The ...

The invention relates to an electrical connector and a contact spring mounting structure thereof. The electrical connector comprises a cylindrical casing and a contact spring. The tubular casing is provided with an annular groove which is closed. The contact spring is installed in the annular groove and is blocked by the groove wall at the annular groove notch to prevent the contact spring from tripping out radially. The groove wall of the annular groove is provided with a notch into which the contact spring is inserted into the annular groove from the circumferential direction. During the installation of the contact spring, the operator only needs to insert one end of the non-closed annular contact spring, such as a C-shape or a straight strip, into the annular groove from the flared groove and push the contact spring completely into the ring in the circumferential direction in the groove. When the contact spring needs to be disassembled, the tail end of the contact spring is pushed to the flared groove by the exposed portion of the contact spring, and then the contact spring is pulled out from the annular groove, which is convenient to install, and the contact spring can be replaced after long-term use.
Description
technical field [0001] The invention relates to an electrical connector and a contact spring installation structure thereof. Background technique [0002] In current high-voltage electrical connectors, a grounding spring is generally provided on the housing to realize shielding grounding of the housing of the electrical connector, thereby improving the safety of the electrical connector during use. In existing electrical connectors, the grounding spring is generally fixed on the housing by welding or other methods. This method is not only inconvenient to install, but also cannot be disassembled after connection, and the grounding spring cannot be replaced after long-term use. Contents of the invention [0003] The purpose of the present invention is to provide a contact spring installation structure that is easy to install and disassemble; the purpose of the present invention is also to provide an electrical connector using the above-mentioned contact spring installation s...
