Description

Technical Field

[0001] This invention relates to the field of connectors, and more particularly to a fixing stud for connectors. Background Technology

[0002] High-current through-wall terminal connectors (or "through-wall connectors") are a common type of connector in the field of photovoltaic storage equipment. Current through-wall connectors mainly consist of a device end and a lead-out end that assemble and cooperate with each other. The device end contains a conductive busbar and fixing studs, which are secured by the shape of the studs. The lead-out end allows external wires to enter and connect electrically to the conductive busbar.

[0003] However, existing connector fixing studs have shortcomings: using the shape of the stud for fixing can cause the stud to wobble, and over time, the stud itself will become loose and abnormal, further reducing the stability of the stud in fixing the connector. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fixing stud for a connector that can meet the self-limiting and fixing requirements of the above-mentioned prior art.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problem is: a connector fixing stud, comprising: The screw body has a threaded section extending along its axis, the threaded section being located between the beginning and end of the screw body; The base is fixed to the end of the screw body; The base is characterized by having a base body on which a limiting groove is formed, located around the axis of the screw body; wherein the limiting groove is configured to limit the degree of freedom of the component to be fixed in the connector.

[0006] Improvedly, in the connector retaining stud, the limiting groove has a groove segment provided around the axis of the screw body.

[0007] In a further improvement, a boss for riveting the conductor of the connector is provided on the base body and above the limiting groove in the fixing stud for the connector.

[0008] Furthermore, in the connector fixing stud, the base body is provided with multiple bosses, and the shapes of the bosses are not exactly the same.

[0009] Furthermore, in the connector fixing stud, all the bosses are arranged circumferentially along the axis of the screw body.

[0010] Alternatively, in the connector fixing stud, the groove segment of the limiting groove can be a closed groove segment or a non-closed groove segment circumferentially around the axis of the screw body.

[0011] Furthermore, in the connector fixing stud, the limiting groove has two groove segments, which are symmetrically arranged on the left and right sides of the screw body.

[0012] In a further improvement, a riveting groove is provided on the base body and below the limiting groove in the fixing stud for the connector.

[0013] Alternatively, in the connector fixing stud, the riveting groove can be a through groove or a non-through groove.

[0014] Compared with the prior art, the advantages of this invention are as follows: The connector fixing stud of this invention, based on an existing stud body and base, adds a base body to the base and forms a limiting groove on the base body located around the axis of the stud body. This limiting groove is configured to limit the degrees of freedom of the component to be fixed within the connector. Thus, when using this fixing stud, the limiting groove of the fixing stud can be used first for limiting and fixing, and then the fixing stud can be used to fix the component to be fixed within the connector. This ensures that the fixing stud itself is limited and fixed, and also enables the fixing stud to fix other components to be fixed within the connector. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0017] This embodiment provides a fixing stud for a connector. Specifically, see... Figures 1-4 As shown, the connector fixing stud of this embodiment includes a screw body 11 and a base 12. The screw body 11 has a threaded segment 11s extending along its axis, the threaded segment 11s being located between the beginning and end of the screw body 11. The base 12 is fixed to the end of the screw body 11, and the base 12 has a base body 120, on which a limiting groove 121 is formed located around the axis of the screw body 11. The limiting groove 121 is configured to limit the degree of freedom of the component to be fixed in the connector (e.g., an NTC element).

[0018] When using the fixing stud in this embodiment, the limiting groove of the fixing stud can be used for limiting and fixing, and then the fixing stud can be used to fix the components to be fixed in the connector. In this way, it can be ensured that the fixing stud itself is limited and fixed, and the fixing stud can also fix other components to be fixed in the connector.

[0019] As a specific form of the aforementioned limiting groove, see [link to relevant documentation] in this embodiment. Figure 1 and Figure 2 The limiting groove (121) here has a groove segment 1210 provided along the periphery of the screw body axis. Of course, the groove segment 1210 of the limiting groove 121 here is either a closed groove segment or a non-closed groove segment along the periphery of the screw body axis.

[0020] In order to more stably limit and fix the stud body and better fix it in the connector, the limiting groove 121 of this embodiment has two groove segments 1210, which are symmetrically arranged on the left and right sides of the screw body 11.

[0021] For the riveting of the connector's internal conductor components using a fixing stud, see [link to documentation]. Figure 2 As shown, a boss 122 for riveting to the conductor of the connector is provided on the base body 120 and above the limiting groove 121.

[0022] To further enhance the riveting effect on the internal conductors of the connector, see [link / reference]. Figure 2 As shown, in this embodiment, the base body 120 is provided with multiple bosses 122, and the shapes of each boss 122 are not exactly the same. For example, all the bosses 122 are arranged circumferentially along the axis of the screw body 11. Of course, the arrangement here is uniform.

[0023] The following combination Figures 1-4 The working principle of the connector fixing stud in this embodiment is explained as follows: When the fixing stud of this embodiment needs to be applied to the connector, the limiting groove on the stud base is first fixed to ensure that the stud itself will not wobble. Then, the connector components to be fixed (such as the conductive busbar 21 of the high current connector and the end of the external wire 22 connecting the conductive busbar 21) are fixed to the stud body. Furthermore, by adding shims and nuts that are fastened to the fixing stud, the fixing stud is fastened to the shims 23 and the nuts 24 respectively, thereby enhancing the connection stability between the fixing stud and the conductive busbar.

[0024] Example 2 This second embodiment provides a fixing stud for a connector. Specifically, see... Figures 5-8 As shown, the difference between the connector fixing stud in Embodiment 1 and the connector fixing stud in Embodiment 2 is that a riveting groove 123 is provided on the base body 120 and below the limiting groove 121. For example, the riveting groove 123 here can be a through groove or a non-through groove as needed.

[0025] The following combination Figures 5-8 The working principle of the connector fixing stud in this second embodiment is explained as follows: When applying the fixing stud of this embodiment to a connector, first, the limiting groove on the stud base is used to limit and fix it, ensuring that the stud itself will not wobble. Then, the connector components to be fixed (such as the conductive busbar of a high-current connector and the end of the external wire connecting the conductive busbar) are fixed to the stud body. Furthermore, by adding washers and nuts that are tightly fitted to the fixing stud, the connection stability between the fixing stud and the conductive busbar is enhanced by the fixing stud being tightly fitted with both the washer and the nut. Moreover, an NTC element used to detect the temperature of the conductive busbar inside the connector can be riveted into the riveting groove of the stud base body, thus completing the riveting of the NTC element to the fixing stud.

[0026] Although preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
