In addition, in the prior art, different types of connectors and the containing shell are split structures, that is, the connector and the containing shell need to be connected by a connecting structure, such as a fastening connection by bolts or screws. Therefore, it is necessary to add additional plastic flanges, sealing rings and other components for connection or sealing, which leads to high costs and low assembly efficiency.

[0047] With the development of clean energy, more and more devices use electric energy as driving energy, and then power batteries that can store more electric energy and can be charged and discharged repeatedly are developing rapidly, such as lithium-ion batteries. Among them, power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields.

[0048] With the country's vigorous promotion of new energy vehicles, new energy vehicles have ushered in a great opportunity for development. The safety and stability of automobiles have always been people's greatest concern. Therefore, improving the safety of new energy vehicles will be one of the important factors that determine whether new energy vehicles can be quickly popularized. Battery modules are the main components of the battery pack of new energy vehicles. Improving the safety of battery modules is an important way to improve the safety of new energy vehicles.

[0049] In the related art, different types of connectors and housings are split structures, that is, the connector and the housing need to be connected by a connection structure, such as bolts or screws. Therefore, additional plastic flanges, sealing rings and other parts are required for connection or sealing, and metal bushings are set at the bolt holes, resulting in high costs and low assembly efficiency.

[0050] In order to reduce costs and improve assembly efficiency, the present application embodiment provides a connector assembly 100. Figures 1 to 4The connector assembly 100 includes a housing 1, a connector shell 2 and a connecting terminal 3. A cavity 1a is provided inside the housing 1. The connector shell 2 and the housing 1 are an integrated structure. A plug-in channel is formed inside the connector shell 2. The plug-in channel connects the cavity 1a and the outside. The connecting terminal 3 is provided in the cavity 1a and is partially plugged into the plug-in channel for mating and connecting with an external plug.

[0051] The connector assembly 100 provided in the embodiment of the present application can be used in different occasions in various fields, and is not specifically limited here. For example, the connector assembly 100 is used for a power battery or an energy storage battery.

[0052] The embodiment of the present application also provides an electrical connection assembly, comprising the connector assembly 100 and a plug according to any embodiment of the present application. The plug is plugged into an end of the plug channel away from the cavity 1a and is matched and connected with the connection terminal 3.

[0053] The connector shell 2 and the containing shell 1 are an integrated structure, which can reduce costs and improve assembly efficiency, that is, the assembly process of the connector assembly 100 can be effectively simplified. In addition, compared with the split connector shell 2 and the containing shell 1, the integrated connector shell 2 and the containing shell 1 have better sealing performance, simple structure and easy operation.

[0054] See also Figure 3 to Figure 4 The accommodating shell 1 is provided with a cavity 1a inside for accommodating and arranging the connecting terminal 3. The accommodating shell 1 is used to provide an installation space for the connecting terminal 3 and to protect the connecting terminal 3 and other components arranged in the cavity 1a.

[0055] The connector housing 2 and the receiving housing 1 are an integrated structure, for example, an integrated injection molding. The integrated connector housing 2 and the receiving housing 1 can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0056] In addition, there is no need to add additional plastic flanges, sealing rings and other components for connection or sealing between the integrated connector housing 2 and the receiving housing 1, thereby reducing production costs. Furthermore, the integrated connector housing 2 and the receiving housing 1 have better sealing performance, which improves the safety performance of the connector assembly 100.

[0057] An inserting channel is formed inside the connector housing 2 , and the connecting terminal 3 and an external plug (not shown) can be matched and connected through the inserting channel inside the connector housing 2 .

[0058] The embodiment of the present application provides a connector assembly 100, which includes a containing shell 1, a connector housing 2 and a connecting terminal 3. A cavity 1a is provided inside the containing shell 1 for accommodating and arranging the connecting terminal 3. A plug-in channel is formed inside the connector housing 2, and the plug-in channel connects the cavity 1a and the outside, so that the connecting terminal 3 and the external plug can be matched and connected through the plug-in channel in the connector housing 2. By setting the connector housing 2 and the containing shell 1 as an integral structure, such as integral injection molding, the number of parts can be reduced, thereby reducing the cost and improving the assembly efficiency, that is, the assembly process of the connector assembly 100 can be effectively simplified. In addition, compared with the split connector housing 2 and the containing shell 1, the sealing between the integrated connector housing 2 and the containing shell 1 is better.

[0059] It should be noted that the specific molding method of the connector housing and the accommodating shell is not limited here.

[0060] In some embodiments, the connector housing and the receiving shell are injection molded parts.

[0061] That is to say, the connector housing and the accommodating shell are injection-molded parts, which has a simple molding process, low manufacturing cost and high production efficiency.

[0062] Injection molding is achieved, for example, by an injection molding machine and a mold. Injection molding is the main molding equipment that uses an injection molding machine to convert thermoplastics or thermosetting materials into plastic products of various shapes using a plastic molding mold.

[0063] In other embodiments, the connector housing and the accommodating shell may also be plastic parts formed by compression molding.

[0064] In some embodiments, see Figures 1 to 4 The connector housing 2 includes a main body 21 and a plug-in portion 22 disposed outside the housing 1. One end of the plug-in portion 22 is connected to a side of the main body 21 away from the housing 1, and the other end extends in a direction away from the housing 1. At least part of the plug-in channel extends to the inside of the plug-in portion 22.

[0065] The main body 21 constitutes the main body 21 part of the connector housing 2 , that is, the main body 21 is used to form the main body 21 part of the plug-in channel, and can improve the structural strength and supporting force of the accommodating shell 1 and the connector housing 2 .

[0066] One end of the plug-in portion 22 is connected to the side of the main body 21 away from the accommodating shell 1, and the other end extends in a direction away from the accommodating shell 1. That is to say, the plug-in portion 22 is arranged on the side of the main body 21 away from the accommodating shell 1, which is more conducive to the plug-in fit between the plug and the connector shell 2.

[0067] At least part of the plug-in channel extends to the inside of the plug-in portion 22, that is, the plug-in channel extends to the inside of the plug-in portion 22, that is, after the plug-in channel passes through the main body 21, it continues to pass through the plug-in portion 22, and the connecting terminals 3 are sequentially arranged in the plug-in channels in the main body 21 and the plug-in portion 22.

[0068] At least part of the plug-in channel extends to the interior of the plug-in portion 22, which means that part of the plug-in channel extends to the interior of the plug-in portion 22, in which case, for example, the plug-in interface of part of the plug-in channel is arranged on the surface of the main body 21, or all of the plug-in channel extends to the interior of the plug-in portion 22, in which case, for example, the plug-in interface of all of the plug-in channels is arranged on the surface of the plug-in portion 22.

[0069] By arranging the plug-in portion 22 on the side of the main body 21 away from the accommodating shell 1, at least part of the plug-in channel extends to the inside of the plug-in portion 22, which is beneficial to the plug-in fit between the plug and the connector shell 2, and is also beneficial to increasing the depth of the plug-in channel, that is, it is beneficial to increase the depth of the connecting terminal 3 inserted in the plug-in channel, thereby improving the connection reliability of the connecting end.

[0070] In some embodiments, see Figure 2 The plug-in channel includes a high-voltage channel 2b and a signal channel 2c. The high-voltage channel 2b passes through the main body 21 and the plug-in portion 22 in sequence. A high-voltage plug-in port 2d communicating with the high-voltage channel 2b is formed at one end of the plug-in portion 22 away from the accommodating shell 1. The signal channel 2c passes through the main body 21. A signal plug-in port 2e communicating with the signal channel 2c is formed at one end of the main body 21 away from the accommodating shell 1.

[0071] The plug-in channel includes a high-voltage channel 2 b and a signal channel 2 c , that is, the connector housing 2 is integrated with the high-voltage channel 2 b and the signal channel 2 c , thereby improving the integration and versatility of the connector assembly 100 .

[0072] The high voltage channel 2 b is, for example, a connection channel for a power terminal.

[0073] A high-voltage plug port 2d communicating with the high-voltage channel 2b is formed at one end of the plug-in portion 22 away from the accommodating shell 1. The high-voltage plug port 2d is used for plugging and mating with an external high-voltage plug.

[0074] By setting the plug-in channel to include a high-voltage channel 2b and a signal channel 2c, the high-voltage channel 2b sequentially passes through the main body 21 and the plug-in portion 22, and a high-voltage plug interface 2d communicating with the high-voltage channel 2b is formed at one end of the plug-in portion 22 away from the accommodating shell 1, and the signal channel 2c passes through the main body 21, and a signal plug interface 2e communicating with the signal channel 2c is formed at one end of the main body 21 away from the accommodating shell 1, that is, an external power plug is plugged into the high-voltage plug interface 2d of the plug-in portion 22, that is, an external signal plug is plugged into the signal plug interface 2e of the main body 21, which is conducive to distinguishing and preventing the high-voltage channel 2b and the signal channel 2c.

[0075] In some embodiments, see Figure 3 The connector assembly 100 further includes an extension portion disposed inside the housing 1. The extension portion and the housing 1 are an integrated structure. One end of the extension portion is connected to the inner side wall of the housing 1 corresponding to the main body 21, and the other end extends in a direction away from the main body 21. A connection channel connected to the plugging channel is formed inside the extension portion. At least part of the connection terminals 3 are plugged into the connection channel and the plugging channel in sequence.

[0076] The extension portion and the accommodating shell 1 are an integrated structure, for example, integrally injection molded.

[0077] One end of the extension portion is connected to the inner side wall of the accommodating shell 1 corresponding to the main body 21, and the other end extends in a direction away from the main body 21. That is to say, the extension portion and the main body 21 are respectively arranged on opposite sides of the shell. In this way, the extension portion can improve the supporting strength of the connector assembly 100. For example, when the plug is mated and connected with the plug-in channel, a certain pressing force will be formed on the connector shell 2. The setting of the extension portion can improve the supporting strength of the connector assembly 100 and can resist deformation of the accommodating shell 1.

[0078] The extension parts and the main body parts 21 may correspond one to one, or the number of the extension parts may be less than the number of the main body parts 21 . Of course, the number of the extension parts may be more than the number of the main body parts 21 .

[0079] At least some of the connection terminals 3 are sequentially plugged into the connection channel and the plugging channel, that is, some of the connection terminals 3 can be sequentially plugged into the connection channel and the plugging channel (for example, power terminals), and some of the terminals can be directly plugged into the plugging channel (for example, signal terminals 32), and all of the connection terminals 3 can be sequentially plugged into the connection channel and the plugging channel.

[0080] By providing the extension part, the support strength of the connector assembly 100 can be improved. For example, when the plug is mated and connected with the plugging channel, a certain pressing force will be formed on the connector housing 2. The provision of the extension part can improve the support strength of the connector assembly 100 and resist deformation of the accommodating housing 1. A connecting channel connected to the plugging channel is formed inside the extension part, so that at least part of the connecting terminal 3 is sequentially plugged into the connecting channel and the plugging channel, so that the strength of the connecting structure between the connecting terminal 3 and the connector housing 2 can be improved.

[0081] In some embodiments, see Figures 1 to 4 The connector housing 2 further includes a guide edge 23 formed on the accommodating housing 1 and / or the main body 21. The guide edge 23 is arranged around the peripheral side of the plug-in portion 22 and can guide the plug to the plug-in position.

[0082] That is, the connector housing 2 also includes a guide edge 23 disposed around the plug portion 22, and can guide the plug to the plugging position. In this way, the guide edge 23 can guide the plug during the rubbing and can position the plug, thereby improving the plugging efficiency and facilitating the plug to be plugged in place.

[0083] The connector housing 2 further includes a guide edge 23 formed on the housing 1 and / or the main body 21. That is, the guide edge 23 may be formed on the housing 1, or on the main body 21, or both the housing 1 and the main body 21 may be formed with the guide edge 23.

[0084] The guide edge 23 arranged around the plug portion 22 is used to position and guide the plug, thereby improving the plugging efficiency of the plug and facilitating the plug to be plugged in place. In addition, the setting of the guide edge 23 can also improve the waterproof sealing performance.

[0085] In some embodiments, please refer to Figures 1 to 4 The guide edge 23 is arranged around the plug-in portion 22, and the two ends of the guide edge 23 in the circumferential direction are arranged at intervals to define an opening 23a. At least part of the plug-in channel is arranged close to the opening 23a.

[0086] The guide edge 23 is spaced at both ends in the circumferential direction to define the opening 23a, which means that the leading end and the trailing end of the guide edge 23 in the circumferential direction are not connected, that is, they are not connected end to end, and the leading end and the trailing end in the circumferential direction are spaced at both ends to define the opening 23a.

[0087] At least part of the plugging channel is arranged close to the opening 23a, that is, the plugging channel is arranged as close to the opening 23a as possible to facilitate plugging the plug from the opening 23a.

[0088] The guide surrounding edge 23 is spaced at both ends in the circumferential direction to define an opening 23a, and at least part of the plugging channel is arranged close to the opening 23a, so as to facilitate plugging the plug from the opening 23a.

[0089] In some embodiments, see Figures 2 to 4 The plug-in channel includes a high-voltage channel 2b and a signal channel 2c, and the connecting terminal 3 includes a high-voltage terminal 31 and a signal terminal 32. The high-voltage terminal 31 is plugged into the high-voltage channel 2b, and the signal terminal 32 is plugged into the signal channel 2c.

[0090] The plug-in channel includes a high-voltage channel 2 b and a signal channel 2 c , that is, the connector housing 2 is integrated with the high-voltage channel 2 b and the signal channel 2 c , thereby improving the integration and versatility of the connector assembly 100 .

[0091] The connection terminal 3 includes a high voltage terminal 31 and a signal terminal 32 . The high voltage terminal 31 is plugged into the high voltage channel 2 b , and the signal terminal 32 is plugged into the signal channel 2 c , thereby improving the integration and versatility of the connector assembly 100 .

[0092] The plug may include a high-voltage plug and a signal plug. The high-voltage plug is plugged into the high-voltage plug interface 2d and is matched with the high-voltage terminal 31 . The signal plug is plugged into the plug interface and is matched with the signal terminal 32 .

[0093] In some embodiments, see Figures 2 to 4 , the number of high-voltage channels 2b is two, the number of signal channel 2c is one, and it is located between the two high-voltage channels 2b.

[0094] By arranging the signal channel 2 c in the middle of the high-voltage channel 2 b , the space of the connector housing 2 can be fully utilized, which is beneficial to improving the compactness of the connector assembly 100 .

[0095] Furthermore, by setting the plug-in part 22, the plug-in part 22 and the main body 21 together form a high-voltage channel 2b, and the signal channel 2c is set in the middle of the high-voltage channel 2b, that is, the signal plug interface 2e is formed between the two plug-in parts 22. In this way, the plug-in part 22 can protect the signal plug and improve the reliability of the connector assembly 100.

[0096] It should be noted that the connection method between the connection terminal 3 and the connector housing 2 is not limited here.
