Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to integrated connectors. Background Technology

[0002] The arrangement of signal harnesses and wires on the battery packs of new energy vehicles is generally quite messy. Currently, some manufacturers integrate multiple interfaces through encapsulated junction boxes for the connection of signal harnesses and wires to the terminals, and then install them on or near the battery pack, which can reduce the messiness of the various harnesses and wires to a certain extent.

[0003] However, current junction boxes are still just simple integrations of various interfaces, which are distributed on different surfaces of the junction box. This makes the overall size of the junction box relatively large and the integration level not high enough.

[0004] Therefore, this application proposes an integrated connector with higher integration. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated connector, which solves the problem that the existing cable management method of connecting various wire harnesses and wires through junction boxes still occupies a large amount of space.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated connector, including a base plate for attachment to a usage scenario and an input terminal, a circuit breaker, and an output terminal connected sequentially on the base plate, and also including a plurality of mounting ports for mounting wire harnesses, wherein the mounting ports are provided on one or more of the base plate, input terminal, circuit breaker, and output terminal.

[0012] Preferably, it also includes a locking member, which is sleeved on the buckle plate and slidably connected to the base. The upper end of the buckle plate on the side facing the base retracts away from the base, so that there is a movable gap between the upper end of the buckle plate and the locking member.

[0013] Preferably, the base has inwardly recessed assembly openings on both sides, and the locking member has lugs on both sides that can extend into the assembly openings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please see Figures 1-7 The present invention provides the following technical solution: an integrated connector, including a base plate 1 for attachment to a usage scenario, and an input terminal 2, a circuit breaker 3, and an output terminal 4 connected sequentially on the base plate 1. The input terminal 2, the circuit breaker 3, and the output terminal 4 each include an insulating housing 21. The interior of the housing 21 is used to install a power-passing component. The circuit breaker 3 is an MSD switch, and the housing 21 of the input terminal 2 is the positive protective cover of the MSD switch. It also includes a plurality of mounting ports 211 for mounting signal harness A. The mounting ports 211 are provided on one or more of the housings 21 of the base plate 1, the input terminal 2, the circuit breaker 3, and the output terminal 4.

[0021] As an optional implementation of this utility model, in use, the wires of the battery pack and the wires of the power terminal are connected to the output terminal 4 and the input terminal 2 respectively. Then, the signal harness A is passed through the mounting port 211, and the base plate 1 is installed on the battery pack or near the battery, making the arrangement of various harnesses A and wires near the battery pack neater. Meanwhile, compared to the prior art where each interface is simply encapsulated and integrated on a junction box (such as...), this method... Figure 7 Compared to the method of connecting each wire harness A and wires to the terminal block (as shown), this technical solution directly integrates the wiring of the signal harness A into the electrical connector connected to the battery pack. Therefore, the overall space occupied is much smaller, which can provide more installation space for the battery pack and other components, and reduce the number of terminals used, saving consumable costs.

[0022] Compared with existing encapsulated junction boxes that implement cable management, this implementation method has a higher degree of integration, significantly increases the installation space for battery packs and related components such as heat dissipation components, saves on the number of terminals used, and reduces consumable costs.

[0023] In this implementation, there are no specific limitations on which housing 21 the mounting port 211 is located on, or on the position and orientation of the housing 21. Any idea that integrates the signal harness A into the electrical connector should fall within the protection scope of this embodiment. The term "electrical component" should refer to wires (conductors) or male and female terminals, etc.

[0024] Furthermore, the mounting port 211 is located on the outer side wall of the housing 21 and penetrates the base plate 1, with the axis of the mounting port 211 perpendicular to the base plate 1.

[0025] As an optional implementation of this utility model, since the positions of the input terminal 2, output terminal 4 and circuit breaker 3 in the electrical connector are generally linearly distributed, and the width of the input and output terminals 4 is narrower than the width of the circuit breaker 3, the base plate 1 should also be a rectangular plate structure to be installed on the battery pack or near the location of the battery pack. If the wiring method is adopted to pass through the electrical connector along the length of the base plate 1 or laterally, it will either cause the wire harness A to bend and affect the communication rate, or cause the base plate 1 to extend to both sides along the width direction or the height of the entire electrical connector to be greater, which will result in an increase in volume. Therefore, designing the mounting port 211 perpendicular to the surface of the base plate 1 to install the signal wire harness A is a more reasonable layout method, which results in a higher degree of integration and helps to reduce space occupation.

[0026] like Figure 6 As shown, each mounting port 211 can be detachably connected to a bracket 5 for fixing the wire harness A. The bracket 5 includes: Insert shell 51 is inserted into mounting port 211. Inside insert shell 51, wire pass plate 511 is snapped in. Wire pass plate 511 is provided with several wire holes 5111 for a single wire harness A to pass through. Locking member 52 is used to fix the insert 51 in the mounting port 211. Locking member 52 includes a base 521 provided on the outer wall of the insert 51, a buckle plate 522 rotatably connected to the base 521 in the middle via a rotating shaft 5221, and a torsion spring 523 sleeved on the rotating shaft 5221. The lower surface of the buckle plate 522 is provided with buckle hole 5222, and the two torsion bars 5231 of the torsion spring 523 abut against the two opposing surfaces of the base 521 and the buckle plate 522 respectively. The outer shell 21 is provided with a locking block 212 that corresponds to and cooperates with the buckle hole 5222.

[0027] As an optional implementation of this utility model, during use, the signal harness A passes through the wire hole 5111 on the wire guide plate 511, the wire guide plate 511 is snapped into the insert shell 51, and then the insert shell 51 is inserted into the mounting port 211. At the same time, the locking block 212 on the outer shell 21 is located in the buckle hole 5222 of the buckle plate 522. Due to the reaction force of the torsion spring 523, the upper end of the buckle plate 522 tends to move away from the insert shell 51, so the lower end of the buckle plate 522 is close to the outer shell 21, so that the buckle hole 5222 locks the locking block 212. Therefore, it can resist some vibration force and prevent the locking block 212 from dislodging from the buckle hole 5222, causing the insert shell 51 to fall off from the mounting port 211, thus ensuring the reliable integration of the signal harness A on the electrical connector.

[0028] When unlocking, press the upper end of the buckle plate 522 to dislodge the buckle hole 5222 from the latch block 212, and then remove the insert shell 51. This provides convenience for users to install and maintain the product themselves after assembly and shipment.

[0029] In this implementation, the positions of the locking block 212 and the buckle hole 5222 can be interchanged. That is, the locking block 212 can be set on the buckle plate 522, and the buckle hole 5222 (can be converted into a buckle groove and set on the outer shell 21). The torsion spring 523 can be designed as a tension spring and installed on the lower part of the outer shell 21 and the buckle plate 522. Of course, these are all equivalent technical means to achieve this function and should all fall within the protection scope of this technical solution.

[0030] Furthermore, it also includes a locking member 524, which is sleeved on the buckle plate 522 and slidably connected in the base 521. The upper end of the buckle plate 522 on the side facing the base 521 contracts away from the base 521, so that there is a movable gap 5223 between the upper end of the buckle plate 522 and the locking member 524. The two side walls of the base 521 are provided with inwardly recessed assembly openings 5211. The two side walls of the locking member 524 are provided with lugs 5241 that can extend into the assembly openings 5211. The protrusion direction of the lugs 5241 on the locking member 524 is perpendicular to the sliding direction of the locking member 524 on the base 521.

[0031] As an optional implementation of this utility model, as mentioned above, the torsion spring 523 can buffer part of the vibration force, but in extreme cases, there is still a risk that the buckle hole 5222 and the locking block 212 may loosen. Therefore, the locking member 524 is first put on the top of the buckle plate 522. After the insert shell 51 is installed, the reaction force of the torsion spring 523 causes the lug 5241 on the locking member 524 to enter the assembly port 5211. Then, the locking member 524 is pushed down to make it slide in the base 521. At this time, the locking member 524 and the buckle plate 522 are completely fitted together, and the assembly tightness is high. Even under high vibration, because the locking member 524 fills the movement allowance of the buckle plate 522, the buckle plate 522 cannot rotate at this time. Therefore, the insert shell 51 will not come off the installation port 211. When unlocking, pull the locking member 524 upward. Due to the radial contraction of the top of the buckle plate 522, there is a certain amount of movement between it and the locking member 524. At this time, pressing the buckle plate 522 will allow the locking block 212 to disengage from the buckle hole 5222 to support the unlocking function.

[0032] In this implementation, the design of the assembly port 5211 and the support ear 5241 allows the locking member 524 to slide on the base 521 while also limiting the sliding stroke of the locking member 524, preventing the locking member 524 from coming off from above after the insert shell 51 is installed.

[0033] Example 2: Please see Figure 1 and Figure 7 The present invention provides the following technical solution: an integrated connector, including a base plate 1 for attachment to a usage scenario, and an input terminal 2, a circuit breaker 3, and an output terminal 4 connected sequentially on the base plate 1. The input terminal 2, the circuit breaker 3, and the output terminal 4 each include an insulating housing 21. The interior of the housing 21 is used to install a power-passing component. The circuit breaker 3 is an MSD switch, and the housing 21 of the input terminal 2 is the positive protective cover of the MSD switch. It also includes a plurality of mounting ports 211 for mounting signal harness A. The mounting ports 211 are provided on one or more of the housings 21 of the base plate 1, the input terminal 2, the circuit breaker 3, and the output terminal 4. Each mounting port 211 can be detachably connected to a bracket 5 for fixing the wire harness A. The bracket 5 includes: Insert shell 51 is inserted into mounting port 211. Inside insert shell 51, wire pass plate 511 is snapped in. Wire pass plate 511 is provided with several wire holes 5111 for a single wire harness A to pass through. Locking component 52, which is a snap-fit ​​525, includes two snap heads 5251 symmetrically arranged on the bottom of the insert housing 51, the two snap heads 5251 being trapezoidal and facing opposite directions.

[0034] As an optional implementation of this utility model, compared to embodiment 1, the snap-fit ​​525 is a more common existing disassembly and assembly method, and it is also relatively convenient to disassemble and assemble the housing 51 directly through the snap-fit ​​525. Furthermore, the circuit breaker 3 is specified as an MSD switch, which is a type of existing circuit breaker. It also has a fuse, which can disconnect the circuit when overheating is caused by current overload, and is also easy to maintain. Its overall structure is as follows... Figure 1 The cube shown facilitates the implementation of a relatively compact overall layout structure in this approach.

[0035] The working principle and usage process of this utility model are as follows: When in use, connect the wires of the battery pack and the wires of the power terminal to the output terminal 4 and the input terminal 2 respectively, then pass the signal harness A through the mounting port 211, and then install the base plate 1 to the battery pack or a position near the battery, so that the arrangement of various harnesses A and wires near the battery pack is more tidy.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
