Especially under low temperature conditions, the performance of power batteries will be affected, so corresponding measures need to be taken to ensure their normal operation. The existing technology often heats the battery module by setting a heating film. The heating film can be designed to be tubular and can be installed in the mounting seat of the plastic part. In order to achieve the electrical connection between the heating film and the battery control system, a connector is required. The double-row connector provides more contact points and can achieve more electrical connections in a smaller space, which is especially important in equipment that requires a compact layout. However, the wiring harness of the double-row connector is thicker, and they need to be bent when connected to the heating film, which may cause stress in the wiring harness.

[0030] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. All other embodiments obtained by those skilled in the art without creative work based on the embodiments in the present application belong to the scope of protection of the present application.

[0032] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] At present, with the continuous development of new energy technology, the storage capacity of power batteries is getting larger and larger, the number of modules is increasing, and the technical requirements for power batteries are getting higher and higher. Especially under low temperature conditions, the performance of power batteries will be affected, so corresponding measures need to be taken to ensure their normal operation. The existing technology often heats the battery module by setting a heating film. The heating film can help increase the temperature of the battery module and ensure that the battery can maintain good performance in a low temperature environment. The heating film can be designed to be tubular and can be installed in the mounting seat of the plastic part.

[0034] In order to achieve the electrical connection between the heating film and the battery control system, a connector is required. The double-row connector 2 provides more contact points, enabling more electrical connections in a smaller space, which is particularly important in devices that require a compact layout. However, the wire harness of the double-row connector 2 is thicker, and when they are connected to the heating film, they need to be bent, which may cause stress in the wire harness.

[0035] The existence of this stress, especially where the wiring harness is bent, will cause the double-row connector 2 to loosen. The loosening of the connector will not only affect the heating effect of the battery module, but may also further affect the performance and safety of the battery. Therefore, solving the problem of the double-row connector 2 loosening due to the stress generated by the bending of the wiring harness is crucial to ensure the normal operation of the power battery under low temperature conditions.

[0036] To solve the above problems, see Figure 1 , Figure 3 and Figure 6 An embodiment of the present application provides a fixing device 1 for a double-row connector 2, which aims to reduce the stress effect caused by the bending of the wiring harness by improving the fixing structure of the double-row connector 2, thereby improving the stability and reliability of the double-row connector 2 during use.

[0037] The fixing device 1 includes a plastic part 10, two mounting seats 20, a first fixing part 30 and a second fixing part 40. The plastic part 10 has a mounting surface 11, and the plastic part 10 also has a first direction XX, a second direction ZZ and a third direction YY, and the first direction XX, the second direction ZZ and the third direction YY intersect each other. The plastic part 10 serves as the basis of the fixing device 1, and the plastic part 10 provides a platform for installing and fixing other components. The plastic part 10 has insulation properties, which can prevent current leakage or short circuit, and ensure the safety of the electrical system.

[0038] The mounting seat 20 is used to install the heating film. The wiring harness of the double-row connector 2 is connected to the heating film and is responsible for transmitting control signals and power so that the heating film can work normally. The plastic part 10 can also prevent dust and other impurities from entering the double-row connector 2 and the heating film, protect the electrical connection from contamination, and extend the service life of the equipment. Specifically, two mounting seats 20 are arranged on the mounting surface 11, and the two mounting seats 20 are arranged opposite to each other. The two mounting seats 20 are at least used to limit the double-row connector 2 in the first direction XX to ensure that the double-row connector 2 is correctly aligned along the first direction XX and initially fixed in place.

[0039] like Figure 4As shown, a guide rib 21 is provided on one side of the mounting seat 20 facing the first fixing member 30. The guide rib 21 can reduce the horizontal distance between the two mounting seats 20, so that the movement margin along the first direction XX is reduced when the double-row connector 2 is engaged with the fixing device 1. The guide rib 21 is used to limit the double-row connector 2 in the first direction XX.

[0040] In another embodiment, the guide rib 21 includes an elastic arm and a hook structure connected to the free end of the elastic arm, the elastic arm can limit the double-row connector 2 in the first direction XX, the hook structure can limit the double-row connector 2 in the second direction ZZ, and the guide rib 21 is arranged adjacent to the wiring harness end of the double-row connector 2, which can reduce the stress caused by bending of the wiring harness end.

[0041] The guide rib 21 has a guide bevel 211, which is inclined in a direction away from the mounting seat 20 and close to the mounting surface 11. The design of the guide bevel 211 allows the double-row connector 2 to slide into a predetermined fixed position along the bevel during assembly, thereby reducing the possibility of improper assembly of the double-row connector 2 and ensuring that the connector is correctly installed in place.

[0042] When the double-row connector 2 is buckled between two guide ribs 21, the spacing between the side end face of the double-row connector 2 and the adjacent guide rib 21 is 0.8mm-1.2mm. This gap range can prevent the double-row connector 2 from excessively moving between the two guide ribs 21, thereby maintaining the stability of the double-row connector 2.

[0043] The first fixing member 30 is arranged on the mounting surface 11 and is located between the two mounting seats 20. The first fixing member 30 is at least used to limit the double-row connector 2 in the second direction ZZ. It can limit the double-row connector 2 in the second direction ZZ of the plastic part 10 to prevent the double-row connector 2 from being displaced or tilted in the direction perpendicular to the plastic part 10; the first fixing member 30 and the wiring harness stress generating point of the double-row connector 2 are located on the same side, which helps to balance the stress of the wiring harness and reduce the loosening or damage of the connector caused by uneven stress, so as to achieve a more secure fixation of the double-row connector 2, improve the transmission quality of signals or currents, and reduce the transmission problems caused by the loosening of the double-row connector 2.

[0044] The second fixing member 40 is disposed on the mounting surface 11. The second fixing member 40 is located at the same end of the two mounting seats 20 and is spaced apart from the two mounting seats 20. The second fixing member 40 is used to limit the double-row connector 2 in the first direction XX at least. The second fixing member 40 is used to additionally limit the double-row connector 2 in the first direction XX of the plastic part 10, and together with the mounting seat 20, provides a more stable fixing effect to prevent the double-row connector 2 from moving in the first direction XX.

[0045] In order to make the connection between the components on the fixing device 1 more secure, the plastic part 10, the two mounting seats 20, the first fixing part 30 and the second fixing part 40 are an integrated structure, which improves the stability and durability of the entire fixing device 1. The integrated molding does not require the individual components to be manufactured separately and then assembled, which can reduce the steps in the manufacturing process and reduce the material and labor costs.

[0046] The plastic part 10 of the present embodiment is provided with a first fixing hole 12 and a second fixing hole 13 both extending along the first direction XX. The first fixing hole 12 is located between the two mounting seats 20 and between the first fixing member 30 and the second fixing member 40. Both ends of the first fixing hole 12 along the first direction XX extend to the two mounting seats 20 respectively. The second fixing hole 13 is located on the opposite side of the first fixing member 30 along the third direction YY. The two end portions of the double-row connector 2 along the third direction YY are respectively embedded in the first fixing hole 12 and the second fixing hole 13, so that the double-row connector 2 is limited in the third direction YY.

[0047] Since the first fixing hole 12 and the second fixing hole 13 are both long holes along the first direction XX, in order to prevent the double-row connector 2 from being displaced in the first direction XX in the long holes, a partition rib 14 is provided in the second fixing hole 13 along the third direction YY. The partition rib 14 can also be used as a positioning point, and together with the two side walls of the second fixing hole 13 along the first direction XX, it defines an embedding space for a single connector, thereby helping to accurately position the double-row connector 2 and ensuring that the double-row connector 2 and the second fixing hole 13 are more precisely matched.

[0048] In some embodiments, the first fixing member 30 includes a first fixing arm 31 and a first buckle 32. The first fixing arm 31 is disposed on the mounting surface 11 and is used to limit the double-row connector 2 in the third direction YY. The first buckle 32 is disposed at the end of the first fixing arm 31 and is protruded toward the direction of the second fixing member 40. The first buckle 32 is used to limit the double-row connector 2 in the second direction ZZ. The design of the first buckle 32 can provide additional fixing force and enhance the connection strength between the double-row connector 2 and the first buckle 32. The first fixing arm 31 and the first buckle 32 provide a stable fixing point to limit the end of the double-row connector 2, thereby enhancing the overall stability of the double-row connector 2. By arranging the first fixing arm 31 and the first buckle 32 at a key position, the design of the fixing device 1 can be simplified, the number of required components can be reduced, and the manufacturing cost can be reduced.

[0049] The sizes of the first fixing arm 31 and the first buckle 32 can be adjusted according to the specific size and shape of the double-row connector 2 to adapt to different application requirements, which is not limited in the present application.

[0050] In some embodiments, one side of the first fixing arm 31 is flush with a side wall surface used to form the first fixing hole 12. When the double-row connector 2 is embedded in the first buckle 32, the first fixing hole 12 can provide a certain elastic displacement space for the first fixing arm 31. When the end of the double-row connector 2 is at least partially embedded in the first fixing hole 12, the first fixing arm 31 just abuts against the end of the double-row connector 2. The first buckle 32 is located above the first fixing hole 12, forming a blocking surface for the double-row connector 2 in the second direction ZZ, and the fixing work is more direct and efficient.

[0051] In some embodiments, Figure 2 As shown, the second fixing member 40 includes a first fixing monomer 41, a second fixing monomer 42 and a common fixing monomer 43, and the common fixing monomer 43 is located between the first fixing monomer 41 and the second fixing monomer 42, that is, the first fixing monomer 41, the second fixing monomer 42 and the common fixing monomer 43 are located on the same horizontal line of the first direction XX. This layout provides symmetry, which helps to balance the forces on both ends of the double-row connector 2 in the first direction XX and reduce the warping caused by the asymmetric layout. Moreover, the first fixing monomer 41, the second fixing monomer 42 and the common fixing monomer 43 are arranged in the middle position of the double-row connector 2 along the third direction YY after being buckled, which can more effectively resist external vibration and reduce the influence of vibration on the connection stability of the double-row connector 2. For the first fixing monomer 41, the second fixing monomer 42 and the common fixing monomer 43, they can also more evenly bear the force that may be applied by the double-row connector 2, reduce the wear of the first fixing monomer 41, the second fixing monomer 42 and the common fixing monomer 43, and enhance durability.

[0052] Specifically, the first fixing unit 41 includes a second fixing arm 411 and a second buckle 412 connected to the end of the second fixing arm 411, the second buckle 412 is protruded toward the direction of the common fixing unit 43, and is used to limit one of the connectors in the double-row connector 2 in the first direction XX and the second direction ZZ; the second fixing unit 42 includes a third fixing arm 421 and a third buckle 422 connected to the end of the third fixing arm 421, the third buckle 422 is protruded toward the direction of the common fixing unit 43, and is used to limit the other connector in the double-row connector 2 in the first direction XX and the second direction ZZ; the common fixing unit 43 includes a fourth fixing arm 431 and a bidirectional buckle 432 connected to the end of the fourth fixing arm 431, the bidirectional buckle 432 has two clamping parts arranged opposite to each other along the first direction XX, and is used to limit the double-row connector 2 in the first direction XX and the second direction ZZ. By dispersing stress on multiple buckles, stress concentration at any single point on the double-row connector 2 can be reduced. By fixing one of the connectors in the double-row connector 2 by the first fixing monomer 41 and the second fixing monomer 42 respectively, each connector can be fixed independently, thereby improving the stability of the overall structure. The existence of the common fixing monomer 43 allows the two connectors to share a fixing point and limit the length and the second direction ZZ at the same time, which helps to simplify the structure of the fixing device 1. The cooperation of the first fixing monomer 41, the second fixing monomer 42 and the common fixing monomer 43 allows the double-row connector 2 to be limited in the first direction XX and the second direction ZZ at the same time, thereby reducing the influence of external vibration on the displacement of the double-row connector 2.

[0053] In some embodiments, the connection between the plastic part 10 and the second fixed arm 411 is provided with a communicating opening groove and an avoidance groove, the opening groove is located on both longitudinal sides of the second fixed arm 411, and the avoidance groove is located on the side of the second fixed arm 411 facing the third fixed arm 421, allowing the second fixed arm 411 to bend or move in the first direction XX to a certain extent, providing a certain adjustment space, and increasing the flexibility of the second buckle 412 at its free end. During the assembly process of the double-row connector 2, the opening groove and the avoidance groove can reduce the stress on the plastic part 10 and the second fixed arm 411, and avoid damage to the second fixed arm 411 due to improper assembly of the double-row connector 2.

[0054] When the double-row connector 2 is buckled into the first fixed monomer 41 and the second fixed monomer 42, the spacing between the side end face of the double-row connector 2 and the second fixed arm 411 is 0.8mm-1.2mm; the spacing between the upper end face of the double-row connector 2 and the second buckle 412 is 0.8mm-1.2mm. The appropriate gap can prevent the double-row connector 2 from being subjected to excessive extrusion during the buckling process, and prevent the first fixed monomer 41 and the second fixed monomer 42 from breaking at the root when the double-row connector 2 is buckled, thereby improving the durability of the buckle. Thereby extending its service life. Furthermore, the first fixed monomer 41 and the second fixed monomer 42 are components with the same structure and are arranged opposite to each other.

[0055] In some embodiments, Figure 4 and Figure 6 As shown, a first accommodating space 10a is formed between the second fixed arm 411 and the fourth fixed arm 431, a first guide opening 10b is formed between the second clip 412 and the two-way clip 432, and the first guide opening 10b is communicated with the first accommodating space 10a, so that one connector in the double-row connector 2 can be assembled to the first accommodating space 10a through the first guide opening 10b; a second accommodating space 10c is formed between the third fixed arm 421 and the fourth fixed arm 431, a second guide opening 10d is formed between the third clip 422 and the two-way clip 432, and the second guide opening 10d is communicated with the second accommodating space 10c, so that another connector in the double-row connector 2 can be assembled to the second accommodating space 10c through the second guide opening 10d. The first guide opening 10b and the second guide opening 10d provide a clear access path, which helps to accurately position the double-row connector 2 and ensure that it is correctly assembled into the first accommodating space 10a and the second accommodating space 10c. On the one hand, it can reduce the time required for assembly because the connector can be directly slid into the accommodating space through the guide opening without the need for a complicated alignment process. On the other hand, it can also reduce wear during assembly and disassembly, which helps to improve the durability of the fixing device 1.

[0056] In some embodiments, the first buckle 32 is formed with a first guide surface 321 on one side facing the bidirectional buckle 432, and the first guide surface 321 is tilted in a direction close to the bidirectional buckle 432 and close to the mounting surface 11; the second buckle 412 is formed with a second guide surface 4121 on one side facing the first guide port 10b, and the third buckle 422 is formed with a third guide surface 4221 on one side facing the second guide port 10d, and the bidirectional buckle 432 is formed with a fourth guide surface 4321 and a fifth guide surface 4322 that are arranged opposite to each other; the second guide surface 4121 is arranged opposite to the fourth guide surface 4321, and the spacing between them gradually decreases in a direction close to the first accommodation space 10a, and the third guide surface 4221 is arranged opposite to the fifth guide surface 4322, and the spacing between them gradually decreases in a direction close to the second accommodation space 10c. On the one hand, it helps to guide the double-row connector 2 to be smoothly assembled into the first accommodation space 10a and the second accommodation space 10c along a specific direction. On the other hand, the first buckle 32, the second buckle 412, the third buckle 422 and the bidirectional buckle 432 have larger limiting mating surfaces with the upper end surface of the double-row connector 2, providing a more stable limiting effect, improving the fixing effect after buckling, and the double-row connector 2 is not easy to leave the fixed position.

[0057] In some embodiments, a partition wall 44 is also included, which is located between the common fixing unit 43 and the first fixing member 30. The partition wall 44 is extended along the third direction YY. The partition wall 44 provides a physical barrier to prevent the two connectors from tilting and warping in the first direction XX due to stress generated by the wiring harness of the double-row connector 2. The existence of the partition wall 44 can also be used as a positioning reference during assembly to improve assembly accuracy.

[0058] In some embodiments, the partition wall 44 is connected to the common fixing monomer 43, which improves the overall rigidity of the partition wall 44 and the common fixing monomer 43, reduces deformation caused by external forces, and enhances the stability of the common fixing monomer 43. The connection between the partition wall 44 and the common fixing monomer 43 provides additional protection to prevent the double-row connector 2 from accidentally tilting when impacted.

[0059] In some embodiments, the thickness of the partition wall 44 is less than the thickness of the fourth fixed arm 431, and both sides of the partition wall 44 along the first direction XX form a step structure with the common fixed monomer 43, increasing the contact area between the common fixed monomer 43 and the double-row connector 2, thereby improving the fixing effect and the stability of the double-row connector 2.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
