In the contact spring installation process, an operator only needs to insert one end of a non-closed annular contact spring in a C shape or a straight strip shape and the like into the annular groove from the flaring groove and completely push the contact spring into the annular groove along the circumferential direction, then the tail end of the contact spring is moved away from the flaring groove through the exposed part of the contact spring to avoid the contact spring from being separated from the flaring groove.
The technical scheme 2 of the contact spring mounting structure is further improved on the basis of the technical scheme 1: the groove wall of the annular groove corresponding to the notch is provided with a slope which guides the contact spring inserted from the notch to enable the contact spring to be smoothly inserted into the annular groove.
The technical scheme 3 of the contact spring mounting structure is further improved on the basis of the technical scheme 1 or 2: the annular groove is located on the outer side surface of the cylindrical base body.
In order to achieve the above object, a technical solution 1 of an electrical connector of the present invention is: an electric connector comprises a cylindrical shell and a contact spring, wherein a closed annular groove is formed in the cylindrical shell, the contact spring is installed in the annular groove and is stopped by a groove wall at the groove opening of the annular groove to prevent the contact spring from radially falling off, and a notch for allowing the contact spring to be circumferentially inserted into the annular groove is formed in the groove wall of the annular groove.
In the contact spring installation process, an operator only needs to insert one end of a non-closed annular contact spring in a C shape or a straight strip shape and the like into the annular groove from the flaring groove and completely push the contact spring into the annular groove along the circumferential direction, then the tail end of the contact spring is moved away from the flaring groove through the exposed part of the contact spring to avoid the contact spring from being separated from the flaring groove.
The technical scheme 2 of the electric connector is further improved on the basis of the technical scheme 1: the groove wall of the annular groove corresponding to the notch is provided with a slope which guides the contact spring inserted from the notch to enable the contact spring to be smoothly inserted into the annular groove.
The technical scheme 3 of the electric connector is further improved on the basis of the technical scheme 1 or 2: the annular groove is located on the outer side surface of the cylindrical shell.

Fig. 1 is a block diagram of an electrical connector embodiment 1 of the present invention;
fig. 2 is a partial cross-sectional view of the contact spring in the circumferential direction in an embodiment 1 of the electrical connector of the present invention;
fig. 3 is a partial cross-sectional view of an electrical connector of embodiment 1 of the present invention taken along the axial direction at the notch;
in the figure: 1. a cylindrical housing; 2. an annular groove; 3. a contact spring; 4. a notch; 41. a ramp.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
A specific embodiment 1 of an electrical connector of the present invention, as shown in fig. 1 to 3, includes a contact spring mounting structure for mounting a contact spring, the contact spring mounting structure including a closed annular groove 2 provided on an outer peripheral surface of a cylindrical housing 1, the annular groove 2 having a cross section in a dovetail groove shape, the annular groove 2 having a contact spring 3 mounted therein, the contact spring being a grounding spring in this embodiment. 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 in the annular groove 2 is larger than or equal to the axial dimension of the contact spring 3, the contact spring is installed in the annular groove and is stopped by the groove wall at the notch of the annular groove to prevent the contact spring from radially falling off, notches 4 for the contact spring to be circumferentially inserted into the annular groove from the notches are further arranged on the groove walls on the two sides of the annular groove, and slopes 41 for guiding the contact spring inserted from the notches to enable the contact spring to be smoothly inserted into the annular groove are arranged on the groove walls of the annular groove corresponding to the notches 4.
In the actual installation process of the electric connector, an operator only needs to insert one end of a C-shaped or straight-bar-shaped non-closed annular contact spring 3 into the annular groove 2 from the notch 4 and completely push the contact spring into the annular groove along the slope 41, then the tail end of the contact spring is moved away from the notch 4 through the part of the contact spring 3 exposed outside to avoid the contact spring from falling off from the notch, when the contact spring 3 needs to be disassembled, the tail end of the contact spring only needs to be pushed to the notch through the part of the contact spring exposed outside, and then the contact spring is pulled out of the annular groove.
Set up the slope on the cell wall that the annular groove corresponds breach department, this slope leads to the installation and the dismantlement of contact spring 3, makes the installation and the dismantlement of contact spring more convenient.
