Description

Connector plug and energy storage connector Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a connector plug and an energy storage connector. Background Art

[0002] Connectors are indispensable components in electronic products, providing power and data connections for circuit systems. Existing energy storage connectors include plugs and sockets. When the plug and socket are plugged together, they need to meet a certain IP rating. Therefore, a groove body for accommodating a sealing ring is usually provided on the outside of the plug. As shown in FIG1 , the sealing ring 110 is installed in the groove body 120 on the outside of the plug end of the plug 100. As shown in FIG2 , during daily use, the sealing ring is often damaged due to the oblique insertion of the plug 100 and the socket 200, which seriously affects the life of the energy storage connector. In addition, if the edge of the socket is accidentally scratched or has burrs, the sealing ring will be pushed out when the plug and socket are plugged together, causing an abnormal condition of the sealing ring, which will fail to meet the IP rating requirements of the energy storage connector. Summary of the Invention

[0003] The purpose of the present application is to provide a connector plug and an energy storage connector to solve the problem of damage to the seal of the existing energy storage connector when the plug and socket are inserted obliquely, as well as the risk of abnormal damage to the seal during daily use.

[0006] As a preferred solution, a guide portion is provided on the outer wall of the second sleeve close to one end of the first sleeve, and a guide groove matching the guide portion is provided on the inner wall of the retaining ring.

[0007] As a preferred solution, the number of the guide portions and the number of the guide grooves are both two and they are symmetrically distributed.

[0008] As a preferred solution, the opening of the guide groove close to one end of the first sleeve is designed to be trumpet-shaped and open outward.

[0009] As a preferred solution, a clamping protrusion is provided on the outer wall of the second sleeve, and a clamping hole for clamping and fixing with the clamping protrusion is provided on the retaining ring.

[0010] As a preferred solution, the number of the clamping protrusions and the clamping holes is two and they are symmetrically distributed.

[0011] As a preferred solution, the outer diameter of the first sleeve is consistent with the outer diameter of the retaining ring, and the outer edge diameter of the seal is larger than the outer diameters of the first sleeve and the retaining ring, so as to achieve sealing when the connector plugs are plugged in.

[0012] As a preferred solution, the plug-in sleeve further includes a fixing column arranged in the center of the plug-in sleeve.

[0013] On the other hand, the present application provides an energy storage connector, comprising the above-mentioned connector plug and a connector socket plugged into the connector plug.

[0028] Example 1

[0029] This embodiment provides a connector plug, which is plugged into a socket to achieve circuit connectivity.

[0030] As shown in FIG3 , the connector plug includes a plug body 10 and a cavity 11 disposed at one end of the plug body 10. A tubular plug sleeve 12 is disposed within the cavity 11, and a center column 14 is disposed within the plug sleeve 12. An annular gap 15 is formed between the outer wall of the plug sleeve 12 and the inner wall of the cavity 11. As shown in FIG4 and FIG5 , the plug sleeve 12 includes a plug body 121 and a retaining ring 122 that is sleeved on the outside of the plug body 121. The plug body 121 has a first sleeve 1211 having a first outer diameter D1 and a second sleeve 1212 having a second outer diameter D2, wherein the first outer diameter D1 is greater than the second outer diameter D2. A sealing groove 123 is disposed on the outer wall of the first sleeve 1211 near one end of the second sleeve 1212. The sealing groove 123 accommodates a seal 13, and the retaining ring 122 is sleeved on the outside of the second sleeve 1212. It is understood that the sealing groove 123 is provided on the outer wall of the first sleeve 1211 near the bottom of the retaining ring 122. The outer diameter of the first sleeve 1211 is consistent with the outer diameter of the retaining ring 122, and the outer edge diameter of the sealing member 13 is larger than the outer diameters of the first sleeve 1211 and the retaining ring 122, so as to achieve a seal when the connector plugs are mated.

[0031] As shown in Figures 6 and 7, a guide portion 124 is provided on the outer wall of the second sleeve 1212 near one end of the first sleeve 1211. The end of the guide portion 124 away from the first sleeve 1211 is in an arc shape. The inner wall of the retaining ring 122 is provided with a guide groove 125 that cooperates with the guide portion 124. The guide groove 125 is open at one end near the first sleeve 1211 and is designed to be flared outward. The above design facilitates the smooth introduction of the guide portion 124 into the guide groove 125, allowing the retaining ring 122 to be quickly plugged into the second sleeve 1212 of the plug body 121. In this embodiment, there are two guide portions 124 and they are symmetrically distributed on the outer wall of the second sleeve 1212, and there are two guide grooves 125 and they are symmetrically distributed on the inner wall of the retaining ring 122.

[0032] Furthermore, as shown in Figures 6 and 7, a snap-fit ​​protrusion 126 is provided on the outer wall of the second sleeve 1212 near the annular gap 15, and a snap-fit ​​hole 127 is provided on the retaining ring 122 for snap-fitting with the snap-fit ​​protrusion 126. In this embodiment, there are two snap-fit ​​protrusions 126, symmetrically distributed on both sides of the second sleeve 1212, and there are more than two snap-fit ​​holes 127, symmetrically distributed on the retaining ring 122. In this embodiment, the guide portion 124 and the snap-fit ​​protrusion 126 are spaced apart and evenly distributed on the outer wall of the second sleeve 1212.

[0033] In the connector plug of this embodiment, the plug sleeve is designed as a plug body and a retaining ring sleeved on the top of the plug body. A sealing groove is provided at one end of the first sleeve of the plug body near the second sleeve. The seal is pre-installed in the sealing groove, and the retaining ring is then fixed to the second sleeve of the plug body. This not only effectively solves the problem of damage to the seal when the connector plug and the socket are inserted at an angle, but also effectively prevents damage to the seal caused by other objects or improper operation during daily use of the plug, reducing the risk of daily damage to the energy storage connector, and ultimately achieving the purpose of extending the service life of the energy storage connector.

[0034] Example 2

[0035] The present application provides an energy storage connector, including the connector plug of Example 1, as shown in Figure 8 , and a socket 2. As can be seen, a seal 13 is pre-buried within a cavity at one end of the plug 1. Compared to prior art techniques in which the seal is exposed outside the plug, this embodiment increases the guide distance of the seal's front end, thereby effectively preventing damage to the seal when the plug and socket are inserted at an angle.

[0036] Obviously, the above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other variations or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the claims of the present application.
