[0055] Exemplary embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] In the prior art, a battery pack includes a sealing cover, a distribution box cover, and a connector. A storage battery is installed on the sealing cover, the distribution box cover is disposed on the storage battery and connected to the sealing cover. A power harness of the storage battery is electrically connected to the connector, and a part of the connector extends out of the distribution box cover to lead out the power harness of the storage battery from the distribution box cover, facilitating electrical connection with electrical equipment outside the distribution box cover. One end of the power harness has an OT terminal, the OT terminal has a plugging hole, and the connector has a threaded hole. The plugging hole and the threaded hole are connected by a bolt to electrically connect the power harness and the connector. However, both the above-mentioned OT terminal and the connector are conductive parts, and care needs to be taken when installing the OT terminal on the connector, resulting in inconvenient operation and poor operation safety.

[0057] Based on this, an embodiment of the present application provides an electrical connection structure, including: a connection seat, at least one connecting member, and a plug-in member. The connection seat is used for connecting to a support surface; the connecting member is connected in the connection seat and is used for connecting a first wire harness; the plug-in member is used for connecting a second wire harness, and the plug-in member is inserted into the connection seat to be electrically connected to the connecting member, so that the first wire harness and the second wire harness can be electrically connected through the connecting member. By inserting the plug-in member into the connection seat, the connecting member can be electrically connected to the second wire harness, making the connection between the second wire harness and the connecting member relatively convenient. By providing the connection seat, the electrical connection part between the connecting member and the plug-in member is located inside the connection seat, so that the electrical connection part can be protected by the connection seat, and the safety is better.

[0058] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0059] Refer to Figures 1 to 7 and Figure 10 An electrical connection structure 10 provided by an embodiment of the present application is disposed on a support surface. The electrical connection structure 10 is used for connecting a first wire harness and a second wire harness 20. The electrical connection structure 10 includes: a connection seat 100, at least one connecting member 200, and a plug-in member 300. The connection seat 100 is used for connecting to the support surface; the connecting member 200 is connected in the connection seat 100 and is used for connecting the first wire harness; the plug-in member 300 is used for connecting the second wire harness 20, and the plug-in member 300 is inserted into the connection seat 100 to be electrically connected to the connecting member 200.

[0060] Among them, an insulating layer is provided outside the second wire harness 20. After the connector 300 is connected to the second wire harness 20, an operator can hold the second wire harness 20 and operate the second wire harness 20 to insert the connector 300 into the connection base 100.

[0061] Specifically, the connector 300 is inserted into the connection base 100 to contact the connector 200 in the connection base 100, so that the connector 300 is electrically connected to the connector 200. The connector 200 is electrically connected to the first wire harness, and the connector 300 is electrically connected to the second wire harness 20, so that the first wire harness and the second wire harness 20 can be electrically connected through the connector 200 and the connector 300.

[0062] It should be noted that both the first wire harness and the second wire harness 20 are power wire harnesses. The power wire harness has a large diameter and is relatively hard and difficult to bend. During the process of inserting the connector 300 into the connection base 100, the second wire harness 20 is bent less, which is convenient for operation.

[0063] The electrical connection structure provided by the embodiment of the present application, by providing the connector 200 and the connector 300, the connector 200 is arranged in the connection base 100, the connector 200 is used to connect the first wire harness, the connector 300 is used to connect the second wire harness 20, and the connector 300 is inserted into the connection base 100 to be electrically connected to the connector 200, so that the first wire harness and the second wire harness 20 are electrically connected through the connector 200. By inserting the connector 300 into the connection base 100, the connector 200 can be electrically connected to the second wire harness 20, so that the connection between the second wire harness 20 and the connector 200 is relatively convenient, and the installation efficiency is improved. By providing the connection base 100, the electrical connection part between the connector 200 and the connector 300 is located in the connection base 100, so that the electrical connection part can be protected by the connection base 100, and the safety is better.

[0064] Refer to Figure 2 、 Figure 3 and Figure 7 , in a specific implementation, the connection base 100 has an insertion interface 121, and the connector 300 includes an insertion block 310. The insertion block 310 is inserted into the insertion interface 121 to be electrically connected to the connector 200.

[0065] Among them, the connector 200 can be partially located in the insertion interface 121, or the connector 200 is located on one side of the insertion interface 121, so that when the insertion block 310 is inserted into the insertion interface 121, it is convenient for the insertion block 310 to contact the connector 200, and then the insertion block 310 is electrically connected to the connector 200.

[0066] Exemplarily, a conductive layer can be provided on the insertion block 310 to facilitate the electrical connection between the insertion block 310 and the connector 200. For example, the conductive layer can be formed by applying conductive paste.

[0067] In this way, by providing the plug-in port 121 , the plug-in block 310 can be inserted into the connection socket 100 through the plug-in port 121 , thereby facilitating the electrical connection between the plug-in component 300 and the connection component 200 .

[0068] Reference Figure 1 , Figure 4 and Figure 5 In a specific implementation, the connection base 100 further has a mounting hole 122 , at least part of the connection member 200 is located in the mounting hole 122 , and the mounting hole 122 is connected to the plug interface 121 .

[0069] By setting the mounting hole 122 , the connector 200 is located in the mounting hole 122 , so that when the plug-in block 310 is inserted into the plug-in port 121 , the plug-in block 310 is conveniently in contact with the connector 200 , thereby facilitating electrical connection between the plug-in block 310 and the connector 200 .

[0070] Reference Figure 4 , Figure 6 and Figure 7 In some embodiments, the connector 200 includes a retractable first fixing portion 231, which is located in the plug-in port 121. The plug-in block 310 has a second fixing portion 311. The first fixing portion 231 is configured to be pushed by the plug-in block 310 to retract into the installation 122 when the plug-in block 310 is inserted into the plug-in port 121, and to extend into the plug-in port 121 when the plug-in block 310 is fully inserted into the plug-in port 121 to connect with the second fixing portion 311.

[0071] Specifically, when the plug block 310 is inserted into the plug port 121, it will contact the first fixing portion 231. As the plug block 310 moves, it will push the first fixing portion 231 to move along the mounting hole 122 toward the side away from the plug port 121, so that the first fixing portion 231 is retracted into the mounting hole 122. When the plug block 310 is fully inserted into the plug port 121, the plug block 310 no longer exerts a thrust on the first fixing portion 231. The first fixing portion 231 moves along the mounting hole 122 toward the plug port 121 to return to the plug port 121 and then connects with the second fixing portion 311, thereby fixing the plug block 310 in the plug port 121, so that the plug connector 300 is stably connected to the connector 200.

[0072] In this way, the first fixing portion 231 is extended and retracted relative to the mounting hole 122 to facilitate the insertion of the plug block 310 into the plug port 121 and connect with the connector 200 . The connection between the plug block 310 and the connector 200 is more stable, and the plug block 310 is not easy to fall out of the plug port 121 .

[0073] In a specific implementation, the first fixing portion 231 is a protrusion, and the second fixing portion 311 is a groove matching the protrusion.

[0074] In this way, the protrusion is inserted into the groove so that the first fixing portion 231 is connected to the second fixing portion 311. At the same time, the connection operation between the first fixing portion 231 and the second fixing portion 311 is relatively simple.

[0075] Exemplarily, the first fixing portion 231 is a spherical protrusion, and the second fixing portion 311 is a spherical groove to facilitate the plugging block 310 to push the first fixing portion 231 to retract.

[0076] Referring to Figure 4 and Figure 6 In a specific implementation, the connecting member 200 further includes a first connecting section 210 and a first elastic member 220. The first elastic member 220 connects the first connecting section 210 and the first fixing portion 231. The first connecting section 210 is connected to the connecting seat 100, and the first elastic member 220 drives the first fixing portion 231 to expand and contract.

[0077] Wherein, the first elastic member 220 is located between the first connecting section 210 and the first fixing portion 231, and the first fixing portion 231 faces the insertion opening 121.

[0078] Exemplarily, the first elastic member 220 is a spring.

[0079] It can be understood that the connection manner between the first connecting section 210 and the connecting seat 100 can be threaded connection, snap connection, pin connection, etc.

[0080] For example, the first connecting section 210 has an external thread, and the inner wall of the mounting hole 122 has an internal thread that matches the external thread. Further, a mating portion is provided on the end surface of the first connecting section 210 facing away from the first elastic member 220. The mating portion is a protrusion or a groove, and the mating portion is non-circular. The mating portion is used to cooperate with an installation tool such as a wrench to facilitate connecting the first connecting section 210 to the inner wall of the mounting hole 122 through an installation tool such as a wrench.

[0081] Specifically, the plugging block 310 pushes the first fixing portion 231 to move towards the first elastic member 220, and then drives the first elastic member 220 to compress through the first fixing portion 231, so that the first elastic member 220 generates an elastic force. When the plugging block 310 is fully inserted into the insertion opening 121, the plugging block 310 no longer has a thrust on the first fixing portion 231. The elastic force of the first elastic member 220 pushes the first fixing portion 231 to move towards the insertion opening 121 so that the first fixing portion 231 is connected to the second fixing portion 311.

[0082] In some examples, the connection base 100 further has a limiting hole which communicates with the mounting hole 122 and the insertion interface 121. The inner diameter of the limiting hole matches that of the first fixing portion 231 so that the first fixing portion 231 can move within the limiting hole. At the same time, the inner diameter of the limiting hole is smaller than that of the mounting hole 122, and the first elastic member and the insertion block 310 are limited by the limiting hole.

[0083] In this way, by being fixed within the connection base 100 through the first connection segment 210, one end of the first elastic member 220 is connected to the first connection segment 210, preventing one end of the first elastic member 220 from moving. Thus, when the first fixing portion 231 faces the first elastic member 220, it can drive the first elastic member 220 to be compressed. The elastic force generated by the compression of the first elastic member 220 is used to push the first fixing portion 231 to move towards the insertion interface 121. Therefore, the telescopic movement of the first fixing portion 231 is realized by setting the first connection segment 210 and the first elastic member 220. At the same time, the elastic force of the first elastic member 220 can press the first fixing portion 231 tightly against the second fixing portion 311, making the connection between the first fixing portion 231 and the second fixing portion 311 relatively stable and reliable.

[0084] Referring Figure 5 and Figure 6 , in specific implementation, the connecting member 200 further includes a second connection segment 230 and a sealing ring 240. The second connection segment 230 connects the first elastic member 220 and the first fixing portion 231, and the sealing ring 240 is sleeved on the second connection segment 230 and abuts against the inner wall of the mounting hole 122.

[0085] In this way, by setting the sealing ring 240, the sealing ring 240 is located between the second connection segment 230 and the inner wall of the mounting hole 122 to seal the second connection segment 230 and the inner wall of the mounting hole 122.

[0086] In specific implementation, the insertion interface 121 matches the insertion block 310, and the insertion interface 121 is non-circular.

[0087] Among them, by setting the insertion interface 121 to be non-circular, after the insertion block 310 is inserted into the insertion interface 121, it is not easy to rotate relative to the insertion interface 121, avoiding affecting the connection between the insertion member 300 and the connecting member 200. At the same time, it avoids the insertion member 300 driving the second wire harness 20 to move and affecting the connection of the second wire harness 20.

[0088] Exemplarily, the side wall of the insertion interface 121 includes a limiting step, and the insertion block 310 has a limiting surface. When the insertion block 310 is inserted into the insertion interface 121, the limiting surface abuts against the limiting step, thereby preventing the insertion block 310 from rotating relative to the insertion interface 121.

[0089] Furthermore, the insertion block 310 has a guiding angle to facilitate the insertion of the insertion block 310 into the insertion interface 121.

[0090] Referring to Figure 5 and Figure 6 In specific implementation, an opening 123 is provided on a side of the mounting hole 122 away from the insertion interface 121, and the opening 123 is used for inserting a first wire harness into the mounting hole 122.

[0091] Wherein, the first wire harness is inserted into the mounting hole 122 through the opening 123 and contacts the connecting member 200, so that the connecting member 200 is electrically connected to the first wire harness. Thus, the connection between the connecting member 200 and the first wire harness is relatively convenient. The connection part between the first wire harness and the connecting member 200 is located in the mounting hole 122, so as to protect the connection part between the first wire harness and the connecting member 200 through the connecting seat 100.

[0092] Exemplarily, internal threads are provided on the inner wall of the mounting hole 122, external threads are provided on the wiring end of the first wire harness, and the wiring end of the first wire harness is inserted into the mounting hole 122 until the wiring end of the first wire harness abuts against the connecting member 200, so that the internal threads are connected to the external threads, thereby fixing the wiring end of the first wire harness in the mounting hole 122.

[0093] Referring to Figure 5 In specific implementation, at least two limiting plates 125 are provided on the periphery of the opening 123, and a part of the first wire harness is accommodated between two adjacent limiting plates 125.

[0094] Wherein, by providing the limiting plates 125, the wiring ends of part of the first wire harness are located between two adjacent limiting plates 125, and then the wiring ends of the first wire harness can be limited by the limiting plates 125, so as to prevent the wiring ends of the first wire harness from rotating relative to the mounting hole 122 and affecting the connection between the first wire harness and the connecting member 200.

[0095] In some embodiments, the number of the limiting plates 125 can also be one. The limiting plate 125 surrounds the periphery of the opening 123, and a part of the first wire harness is accommodated between the two sides of the limiting plate 125.

[0096] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments, the connecting seat 100 includes a connecting seat body 110 and a support member 120. The support member 120 is connected to the connecting seat body 110. The connecting member 200 is connected in the support member 120. The insertion interface 121 is located on the support member 120, and the connecting seat body 110 is used for connecting to a support surface.

[0097] Wherein, the support member 120 is supported by the connecting seat body 110, and the connecting member 200 and the plug-in member 300 are connected by the support member 120.

[0098] Exemplarily, the connection base body 110 is a plastic part, the support member 120 can be a steel structure part, and the mounting hole 122 is also located on the support member 120.

[0099] It should be noted that, with reference to Figure 4 , the support member 120 can be integrally formed. With reference to Figure 6 , the support member 120 can also be divided into two parts and formed by splicing the two parts.

[0100] It can be understood that the shape of the connection base body 110 can be adaptively set according to actual needs, and this embodiment does not limit it here. The support member 120 can be embedded on the connection base body 110.

[0101] With reference to Figure 2 and Figure 3 , in specific implementation, the connection base body 110 has a mounting groove 114, and the support member 120 is located in the mounting groove 114.
