Technical Field

[0001] The utility model relates to the technical field of wire harness connection, in particular to a wire connector, a wire harness assembly and a vehicle. Background Art

[0002] A wire connector is usually provided in a vehicle, and the wire connector is used to connect the wiring harness in the vehicle. The wire connector includes a shell, a conductive member, and a cover body, and the shell is formed with an installation cavity and a wiring port connected to the installation cavity. The wiring harness terminals of the wiring harness can extend into the installation cavity through the wiring port and are connected to each other through the conductive member provided in the installation cavity. The cover body covers the opening of the installation cavity, and the cover body is provided with a locking structure. When the cover body is pressed toward one side of the installation cavity, the locking structure on the cover body can lock the wiring harness terminals in the installation cavity, thereby ensuring the stability of the connection between the wiring harness terminals and the conductive member.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0059] Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0060] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] In the related art, the locking structure of the wire connector is easily touched by mistake during transportation, resulting in premature locking. To solve the above problem, the utility model proposes a vehicle, which can be an electric car, a fuel car, a forklift, or a truck, and the utility model does not limit this.

[0062] The vehicle includes a frame and an information transmission system. The frame serves as the structural skeleton of the vehicle and is used to support, fix and connect the various assemblies of the vehicle and bear the loads inside the vehicle system and from the external environment. The information transmission system is used to transmit information to various control units of the vehicle. Information transmission includes but is not limited to information transmission between the vehicle control unit and the dashboard control unit, information transmission between the dashboard control unit and the reducer control unit, and information transmission between the reducer control unit and the vehicle control unit. The information transmission system has a wiring harness assembly, which is connected between the control units to realize information transmission between the control units.

[0063] Please refer to Figure 1 The wiring harness assembly 3000 includes a wiring harness 2000 and a wire connector 1000. The wiring harness 2000 is connected to each control unit to realize information transmission between each control unit. The wiring harness 2000 can be a CAN line, a LIN line, a FlexRay line, or a MOST line, and the utility model does not limit this.

[0064] The wiring harness 2000 has a wiring harness terminal 2100, which can be a terminal with a plug, i.e., a male terminal, or a terminal with a jack, i.e., a female terminal, and the present invention does not limit this. The wiring harness 2000 extends into the wire connector 1000 through the wiring harness terminal 2100 to achieve electrical connection between the wiring harness 2000 and the wiring harness 2000.

[0065] The wire connector 1000 is used to connect the wire harness terminals 2100 of the wire harness 2000. It should be noted that the wire connector 1000 can be used to connect different wire harness terminals 2100 in one wire harness 2000, or can be used to connect different wire harness terminals 2100 in different wire harnesses 2000, and the present application does not impose any restrictions on this.

[0066] Please refer to Figures 2 to 4The wire connector 1000 includes a housing 1 and a cover 2. The housing 1 has an installation cavity 11. One side of the housing 1 has an opening 111 communicating with the installation cavity 11. The cover 2 is disposed at the opening 111. The cover 2 is used to lock the wiring harness terminal 2100. The side of the cover 2 facing away from the installation cavity 11 is closer to the bottom of the installation cavity 11 than the edge of the opening 111. The technical solution of the utility model uses the cover 2 to lock the wiring harness terminal, and buries the cover 2 in the opening 111 of the installation cavity 11, so as to reduce the possibility of the cover 2 contacting with external forces, thereby reducing the possibility of the wire connector 1000 being locked by mistake, reducing the loss of the wire connector 1000 during transportation or assembly, and reducing the wiring cost.

[0067] Hereinafter, the structure of the wire connector 1000 will be described in detail with reference to the accompanying drawings.

[0068] Please refer to Figures 3 to 5 The wire connector 1000 includes a shell 1, which serves as the structural skeleton of the wire connector 1000 and is used to support, fix and connect the various components of the wire connector 1000. The shape of the shell 1 can be rectangular, square, or other regular or irregular shapes, and the utility model does not limit this. The material of the shell 1 can be metal, plastic, or fiber, and the utility model does not limit this. In one embodiment of the utility model, the shell 1 is made of nylon to reduce the weight of the shell 1, thereby reducing the weight of the wire connector 1000 and preventing the weight of the wire connector 1000 from damaging the wiring harness 2000.

[0069] The housing 1 has an installation cavity 11 with an opening 111 on one side and a wiring port 112 connected to the installation cavity 11. The wiring ports 112 may be two or more, and the present invention does not limit this. For example, in one embodiment of the present invention, two wiring ports 112 are provided, and the wiring harness terminals 2100 of the wiring harness 2000 extend into the installation cavity 11 from the two wiring ports 112 respectively, and realize electrical connection in the installation cavity 11. Please refer to Figure 1 and Figure 4In one embodiment of the present invention, the wiring harness terminal 2100 extends from the wiring port 112 into the installation cavity 11 along the first direction, and the wiring harness terminal 2100 is provided with an elastic clamp 2110, one end of the elastic clamp 2110 is connected to the wiring harness terminal 2100, and the other end extends to the side away from the wiring harness terminal 2100, and the installation cavity 11 is provided with a locking block 14 arranged along the second direction, and the second direction is perpendicular to the first direction. In a specific application, when the wiring harness terminal 2100 extends from the wiring port 112 into the installation cavity 11 along the first direction, the elastic clamp 2110 provided on the wiring harness terminal 2100 will contact the locking block 14, and the second end of the elastic clamp 2110 will move toward the side close to the wiring harness terminal 2100 under the push of the locking block 14, while making room, so that the wiring harness terminal 2100 can continue to move into the installation cavity 11 through the locking block 14. When the wiring harness terminal 2100 passes through the locking block 14, the second end of the elastic clamp 2110 will return to the side away from the wiring harness terminal 2100, and at this time, the second end of the elastic clamp 2110 facing the wiring port 112 will contact the side of the locking block 14 facing away from the wiring port 112, thereby preventing the wiring harness terminal 2100 from withdrawing outward, thereby achieving a single locking of the wiring harness terminal 2100.

[0070] Please refer to Figure 2 The housing 1 includes a bottom wall 17, a first side wall 18 and a second side wall 19 which are connected to each other. The bottom wall 17, the first side wall 18 and the second side wall 19 are arranged to form a mounting cavity 11. The bottom wall 17, the first side wall 18 and the second side wall 19 can be formed as one piece or can be formed separately and then connected to each other. This application does not limit this. In one embodiment of this application, the first side wall 18 and the second side wall 19 are provided with a notch 16, which is connected to the mounting cavity 11. The assembler can observe the clamping condition of the first clamping member 32 and the locking boss 31 through the notch 16, and then quickly judge the locking condition of the locking structure 3 for the wiring harness terminal 2100, thereby improving the connection efficiency of the wiring harness 2000.

[0071] Please refer to Figures 5 to 7 The connector further includes a cover 2. The cover 2 can, on the one hand, cover the opening 111 to prevent external moisture and dust from entering the installation cavity 11 and affecting the normal use of the wiring harness terminal in the installation cavity 11. On the other hand, the cover 2 can be driven by an external force to move into the installation cavity 11, thereby performing a secondary locking on the wiring harness terminal extending into the installation cavity 11, thereby improving the reliability of the connection between the wiring harness terminal and the wire connector.

[0072] In order to prevent the cover 2 from being touched by mistake, in one embodiment of the present application, the cover 2 is disposed in the opening 111, and the side of the cover 2 facing away from the installation cavity 11 is closer to the bottom of the installation cavity 11 than the edge of the opening 111. In this way, the cover 2 is buried in the opening 111 of the installation cavity 11, thereby reducing the possibility of the cover 2 being in contact with external forces, reducing the possibility of the wire connector 1000 being locked by mistake, reducing the loss of the wire connector 1000 during transportation or assembly, and reducing the wiring cost.

[0073] The cover body 2 is provided with a locking structure 3, which can be extended between the wiring harness terminal and the wiring port under the drive of the cover body 2, so as to replace the locking block 14 to achieve secondary locking of the wiring harness terminal 2100 after the locking block 14 fails to lock the elastic clamp 2110, thereby improving the reliability of the connection between the wire connector 1000 and the wiring harness terminal 2100. It can be understood that in some possible implementations of the present application, the locking block 14 may not be provided in the installation cavity 11, but only the locking structure 3 is used to achieve the locking of the wiring harness terminal 2100, and the present application does not limit this.

[0074] In order to drive the locking structure 3 to move, the cover body 2 includes a main body 21 and an elastic part 22. The main body 21 is the main body of the cover body 2 and is used to be fixedly connected to the housing 1 to fix the cover body 2 on the housing 1. There are many ways to connect the main body 21 to the housing 1. The main body 21 can be connected to the housing 1 by threads or by snaps, and this application does not limit this. In one embodiment of the present application, the wire connector 1000 also includes a second snap-fitting member 24, which is used to connect the main body 21 to the housing 1. The second snap-fitting member 24 includes a second connecting portion 241 and a second snap-fitting member 242. One end of the second connecting portion 241 is connected to the main body 21, and the other end is connected to the second snap-fitting member 242. Correspondingly, the side wall surface of the mounting cavity 11 is provided with a second mounting platform 13. When the cover body 2 is covered on the opening 111, the second snap-fitting member 242 enters the mounting cavity 11 and is mutually buckled with the second mounting platform 13. At this time, the second clamping portion 242 facing the opening 111 contacts the second mounting platform 13 facing away from the opening 111 , thereby limiting the movement of the main body 21 away from the opening 111 , thereby achieving a fixed connection between the main body 21 and the housing 1 .

[0075] One end of the elastic part 22 is connected to the main body 21, and the locking structure 3 is arranged on the side of the elastic part 22 facing the installation cavity 11. The elastic part 22 can be elastically deformed under the action of external force to drive the locking structure 3 to extend into the installation cavity 11, thereby realizing secondary locking of the wiring harness terminal 2100.

[0076] The main body 21 and the elastic part 22 may have various structural forms. For example, in some embodiments, the main body 21 and the elastic part 22 are made of different materials. The main body 21 is made of hard materials such as metal or hard plastic to provide support for the elastic part 22. The elastic part 22 is made of elastic materials such as rubber or elastic foam. When an external force acts on the elastic part 22, the elastic part 22 can be elastically deformed due to the characteristics of the rubber or elastic foam, thereby driving the locking structure 3 to move into the installation cavity 11.

[0077] In one possible implementation of the present application, the thickness of the main body 21 is greater than the thickness of the elastic part 22. In this way, when the cover body 2 is subjected to pressure in the direction of the installation cavity 11, the elastic part 22, which has a thickness less than that of the main body 21, will move in the direction of the installation cavity 11, thereby driving the locking structure 3 to move. The main body 21 can remain unchanged under the pressure, thereby achieving support for the elastic member. Since in this implementation, the elastic deformation of the elastic part 22 and the main body 21 is mainly controlled by thickness, rather than material properties, in this embodiment, the elastic part 22 and the main body 21 can be made of the same material and integrally formed, thereby reducing the manufacturing cost of the cover body 2, thereby reducing the manufacturing cost of the wire connector 1000.

[0078] The locking structure 3 includes a locking boss 31, which is arranged on the side of the elastic part 22 facing the installation cavity. The locking boss 31 is used to extend between the wiring harness terminal and the wiring port when the elastic part 22 extends into the installation cavity 11, thereby preventing the wiring harness terminal from moving toward the wiring port, thereby achieving locking of the wiring harness terminal 2100 in the installation cavity 11.

[0079] The locking structure 3 also includes a first clamping member 32, which includes a first connecting portion 321 and a first clamping portion 322. One end of the first connecting portion 321 is connected to the elastic portion 22, and the other end is connected to the first clamping portion 322. The first clamping portion 322 is provided with a second matching surface that is inclined. Correspondingly, the side wall surface of the mounting cavity 11 is provided with a first mounting platform 12, and the first mounting platform 12 is provided with a first matching surface that is inclined. When the wire connector is in an unlocked state, the first clamping portion 322 is suspended above the first mounting platform 12. When the wire connector enters a locked state, the elastic portion 22 of the cover plate is stressed, and the locking structure 3 moves into the mounting cavity 11 driven by the elastic portion 22, and the locking boss 31 of the locking structure 3 extends between the wiring terminal and the wiring port. Driven by the elastic part 22, the first clamping part 322 moves to the bottom of the first mounting platform 12, and the second mating surface of the first clamping part 322 contacts the first mating surface of the first mounting platform 12, thereby fastening the first clamping part 322 to the first mounting platform 12. In this way, when the external force is removed and the elastic part 22 moves upward again, the first mounting platform 12 can form abutment with the first clamping part 322, thereby preventing the elastic part 22 from moving upward again, thereby achieving the clamping of the elastic part 22 in the mounting cavity 11, and finally making the locking boss 31 connected to the elastic part 22 always maintain between the wiring harness terminal 2100 and the wiring port 112, thereby locking the wiring harness terminal 2100.

[0080] The locking boss 31 and the first clamping member 32 can be integrally formed with the elastic portion 22, or they can be separately formed and then connected to each other, and the present invention does not limit this. In one embodiment of the present invention, the locking boss 31 and the first clamping member 32 can be integrally formed with the elastic portion 22, so as to reduce the manufacturing cost of the cover 2 and the locking structure 3, thereby reducing the manufacturing cost of the wire connector 1000.

[0081] It can be understood that the locking structure 3 can also adopt other methods to lock the wiring harness terminal 2100 provided in the installation cavity 11 when the cover body 2 moves into the installation cavity 11. Specifically, in other possible embodiments of the present invention, the side wall surface of the installation cavity 11 is provided with a first magnetic attraction portion, and the locking structure 3 includes a fixed protrusion and a second magnetic attraction portion. The fixed protrusion is provided on the side of the cover body 2 facing the installation cavity 11, and the second magnetic attraction portion is provided on the side of the cover body 2 facing the side wall of the installation cavity 11. When the cover plate moves toward the installation cavity 11 under the action of external force, the second magnetic attraction portion will move downward with the cover plate, and will be aligned with the first magnetic attraction provided on the side wall of the installation cavity 11, and the second magnetic attraction portion and the first magnetic attraction portion will be magnetically attracted to each other, thereby fixing the cover plate in the installation cavity 11. At this time, the fixed protrusion provided on the cover plate is just provided between the wiring harness terminal 2100 and the wiring port 112, thereby realizing the secondary locking of the wiring harness terminal 2100.

[0082] Please refer to Figure 4 The wire connector 1000 further includes a conductive member 4, which is disposed in the mounting cavity 11 and is used to connect the wiring harness terminals 2100 to each other. The conductive member 4 can have various structural forms, please refer to Figure 8 When the wiring harness terminal 2100 adopts a female terminal, the conductive member 4 includes a first body 41 and a pin 42. The first body 41 serves as the main structure of the conductive member 4 and is used to support and connect the pin 42. The pin 42 is used to be inserted into the wiring harness terminal 2100 when the wiring harness terminal 2100 extends into the installation cavity 11. The number of pins 42 can be two, four, or six, and the utility model does not limit this. The pins 42 can be symmetrically arranged at both ends of the first body 41, can be asymmetrically arranged at both ends of the first body 41, and can also be arranged circumferentially along the first body 41, and the utility model does not limit this. For example, in this embodiment, the wiring harness 2000 includes a first wiring harness 2000a and a second wiring harness 2000b, the first wiring harness 2000a has a first wiring harness terminal 2100a, the second wiring harness 2000b has a second wiring harness terminal 2100b, the pin 42 includes a first pin 42a and a second pin 42b, the first pin 42a is connected to the first wiring harness terminal 2100a, and the second pin 42b is connected to the second wiring harness terminal 2100b. The current of the first wiring harness 2000a can be transferred to the first pin 42a through the first wiring harness terminal 2100a, transferred from the first pin 42a to the first body 41, transferred from the first body 41 to the second pin 42b, transferred from the second pin 42b to the second wiring harness terminal 2100b, and finally transferred to the second wiring harness 2000b through the second wiring harness terminal 2100b, thereby realizing the electrical connection between the first wiring harness 2000a and the second wiring harness 2000b.

[0083] Please refer to Fig. 9When the wiring harness terminal 2100 adopts a male terminal, the conductive member 4 includes a second body 43 and a slot 44 provided in the second body 43. The slot 44 is used to contact the pin of the wiring harness terminal 2100 when the wiring harness terminal 2100 extends into the installation cavity 11, thereby realizing the electrical connection between the wiring harness terminal 2100 and the conductive member 4.
