Description

Technical Field

[0001] The utility model relates to the technical field of power harnesses, in particular to a power harness that can be quickly connected. Background Art

[0002] New energy vehicles refer to vehicles that use new energy to replace traditional fuel vehicles, mainly including pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. The power harness refers to a harness used to transmit electricity in a car. It is mainly used to connect various electric devices, sensors, control units and batteries of the vehicle to provide the vehicle with the electrical energy required to power it.

[0003] When fixing some existing power harnesses at the connection with the motor, it is necessary to first push the raised end of the harness into the interior of the connection, and then rotate the clamping plate on the surface of the harness to press it against the raised plate at the connection, which is rather troublesome. In addition, the interface and wires of such power harnesses are usually integrated. When the wires are damaged, the entire power harness needs to be replaced, resulting in a waste of resources.

[0004] Therefore, those skilled in the art provide a power harness that can be quickly connected to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a power wiring harness that can be quickly connected is proposed. Three wires are fixed by setting an upper cover plate and a lower cover plate. When the wires are damaged, the wires can be conveniently removed without replacing the entire wiring harness, thereby reducing the waste of resources. By setting the upper cover plate, only one step is required to fix the wiring harness, which is more convenient and quick.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power harness that can be quickly connected, comprising a first fixing mechanism, a second fixing mechanism and three wires, wherein the first fixing mechanism comprises an upper cover plate, three first fixing blocks, three conducting plates, two T-shaped blocks, two first pressing blocks, a containing shell, a second pressing block, two first L-shaped plates and two second L-shaped plates, a second return spring is fixedly arranged between the second pressing block and the inner bottom surface of the containing shell, and a third return spring is respectively fixed between the two first L-shaped plates and the inner walls on both sides of the containing shell;

[0007] A first return spring is fixedly arranged between the two first pressing blocks and the two T-shaped blocks. The second fixing mechanism includes a lower cover plate and three second fixing blocks. The front sides of the two side end surfaces of the lower cover plate are fixedly arranged with stab plates. The front side of the lower end surface of the lower cover plate is fixedly arranged with three conductive cylinders.

[0008] Through the above technical scheme, the second pressing block is squeezed while the lower cover is held and pushed into the connection. When the second pressing block is squeezed, the arc block on the surface of the second pressing block abuts against the arc block on the surface of the first L-shaped plate, thereby driving the two first L-shaped plates to move in opposite directions. When it is impossible to push further, the squeezing of the second pressing block is released. At this time, the second L-shaped plate abuts against the end face of the connection, thereby fixing the wiring harness at the connection. By squeezing the two first pressing blocks toward the middle while holding the upper cover and moving it upward, when the first pressing block is squeezed, the first pressing block leaves the inner wall of the lower cover, thereby releasing the clamping connection between the upper cover and the lower cover, and the wire can be removed from the surface of the second fixing block.

[0009] Furthermore, the upper cover plate is clamped with the lower cover plate, the three second fixing blocks are fixedly arranged on the rear side of the inner bottom surface of the lower cover plate, and the three wires are clamped between the upper cover plate and the lower cover plate;

[0010] Through the above technical solution, the three wires are clamped by the upper cover plate and the lower cover plate, making it more convenient to replace the wires.

[0011] Furthermore, the three first fixing blocks are fixedly arranged on the rear side of the inner top surface of the upper cover plate, the three conducting plates are fixedly connected to the three first fixing blocks respectively, and the three conducting plates are movably connected to the three conducting tubes respectively;

[0012] Through the above technical solution, the first fixing block is set to be insulated, so that the current of the wire is transmitted from the conductive plate to the conductive cylinder, and finally the conductive cylinder conducts the current to the inside of the motor.

[0013] Furthermore, the upper end surfaces of the two T-shaped blocks are respectively fixedly arranged at the front positions on both sides of the inner top surface of the upper cover plate, and the two first pressing blocks are respectively slidably sleeved on the opposite sides of the outer end surfaces of the two T-shaped blocks;

[0014] Through the above technical solution, the first pressing block is limited by the T-shaped block, so that the first pressing block is more stable when moving.

[0015] Furthermore, the accommodating shell is embedded in the middle position of the upper end surface of the upper cover plate, and the second pressing block is slidably arranged in the middle position between the front side and the rear side inner wall of the accommodating shell;

[0016] Through the above technical solution, the second pressing block is limited by the accommodating shell, so that the second pressing block is more stable when moving.

[0017] Furthermore, the two first L-shaped plates are respectively slidably disposed on the upper sides of the end surfaces of both sides of the accommodating shell, and the two second L-shaped plates are respectively slidably disposed on the lower end surfaces of the two first L-shaped plates;

[0018] Through the above technical solution, when using the upper cover plate, the second L-shaped plate can be adjusted according to the position of the convex plate at the connection. When the second pressing block is squeezed, the second L-shaped plate is driven not to abut against the stab plate. At this time, the second L-shaped plate can be held and moved.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a power harness that can be quickly connected. Before use, the second pressing block is squeezed while the two second L-shaped plates are held and moved, so that the second L-shaped plates can be adjusted according to the position of the convex plate at the connection, thereby improving practicality. When in use, the second pressing block is squeezed while the lower cover is held and pushed into the connection. When it cannot be pushed in further, the squeezing of the second pressing block is released. At this time, the two second L-shaped plates are abutted against the end faces of the connection, thereby fixing the lower cover and the connection together. By setting the upper cover, only one step is required to fix the wiring harness, which is more convenient and quick.

[0021] 2. The utility model proposes a power harness that can be quickly connected. By squeezing two first pressing blocks toward the middle while holding the upper cover and moving it upward, the clamping connection between the upper cover and the lower cover is released. At this time, the wires can be removed from the surface of the second fixing block. The three wires are fixed by setting the upper cover and the lower cover. When the wires are damaged, they can be easily removed without replacing the entire wiring harness, thereby reducing the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-6 The utility model provides an embodiment: a power harness that can be quickly connected, including a first fixing mechanism 1, a second fixing mechanism 2 and three wires 3, the first fixing mechanism 1 includes an upper cover plate 101, three first fixing blocks 102, three conductive plates 103, two T-shaped blocks 104, two first pressing blocks 105, a housing shell 107, a second pressing block 108, two first L-shaped plates 110 and two second L-shaped plates 111, and the second pressing block 108 is fixedly arranged between the inner bottom surface of the housing shell 107 There is a second return spring 109, and third return springs 112 are respectively fixed between the two first L-shaped plates 110 and the inner walls on both sides of the accommodating shell 107. The accommodating shell 107 is embedded in the middle position of the upper end surface of the upper cover plate 101, and the second pressing block 108 is slidably set in the middle position between the front and rear inner walls of the accommodating shell 107. The two first L-shaped plates 110 are respectively slidably set on the upper sides of the end surfaces of both sides of the accommodating shell 107, and the two second L-shaped plates 111 are respectively slidably set on the lower end surfaces of the two first L-shaped plates 110.

[0032] Before using the wiring harness, the second pressing block 108 is squeezed while the two second L-shaped plates 111 are held and moved. When the second pressing block 108 is moved to a suitable position, the squeezing of the second pressing block 108 is released. When squeezing the second pressing block 108, the arc-shaped block on the surface of the second pressing block 108 abuts against the arc-shaped block on the surface of the first L-shaped plate 110, thereby driving the two first L-shaped plates 110 to move in opposite directions. At this time, the first L-shaped plate 110 drives the second L-shaped plate 111 to move together, so that the end surface of the second L-shaped plate 111 does not abut against the convex block of the stab plate 204, thereby releasing the fixation of the second L-shaped plate 111. When the wiring harness is assembled, the second pressing block 108 is squeezed while holding the lower cover 201 and pushing it into the connection. When it is impossible to push it in further, the squeezing of the second pressing block 108 is released. At this time, the second L-shaped plate 111 is abutted against the end face of the connection, thereby fixing the wiring harness at the connection. In this process, the second L-shaped plate 111 is simply fixed to the inner wall of the first L-shaped plate 110 by the friction between the surface and the inner wall of the first L-shaped plate 110. When the second L-shaped plate 111 is abutted against the end face of the connection, the end face of the second L-shaped plate 111 is also abutted against the stab plate 204, thereby fixing the second L-shaped plate 111 to the inner wall of the first L-shaped plate 110.

[0033] The first return spring 106 is fixedly arranged between the two first pressing blocks 105 and the two T-shaped blocks 104. The second fixing mechanism 2 includes a lower cover plate 201 and three second fixing blocks 202. The front sides of the two side end surfaces of the lower cover plate 201 are fixedly arranged with stab plates 204. The front side of the lower end surface of the lower cover plate 201 is fixedly arranged with three conductive cylinders 203. The upper cover plate 101 is clamped with the lower cover plate 201. The three second fixing blocks 202 are fixedly arranged on the rear side of the inner bottom surface of the lower cover plate 201. The three conductors 3 are clamped. The three first fixing blocks 102 are fixedly arranged on the rear side of the inner top surface of the upper cover plate 101, the three conducting plates 103 are fixedly connected to the three first fixing blocks 102 respectively, the three conducting plates 103 are movably connected to the three conducting tubes 203 respectively, the upper end surfaces of the two T-shaped blocks 104 are fixedly arranged on the front sides of the inner top surface of the upper cover plate 101, and the two first pressing blocks 105 are slidably sleeved on the opposite sides of the outer end surfaces of the two T-shaped blocks 104.

[0034] When the wire harness is in use, the current of the wire 3 is transmitted from the conductive plate 103 to the conductive cylinder 203, and then the conductive cylinder 203 conducts the current to the inside of the motor, and the first fixing block 102 and the second fixing block 202 are both insulated, so that the current will not be conducted to the surface of the upper cover 101 and the lower cover 201. When the wire 3 is replaced, the two first pressing blocks 105 are squeezed toward the middle while holding the upper cover 101 and moving upward. When squeezing the first pressing block 105, the first pressing block 105 leaves the lower cover 101. The inner wall of the cover plate 201 is moved, thereby releasing the clamping connection between the upper cover plate 101 and the lower cover plate 201. At this time, the wire 3 can be removed from the surface of the second fixing block 202, and then a new wire 3 is placed on the surface of the second fixing block 202. The wire 3 is simply fixed by the cylinder on the surface of the second fixing block 202 to prevent it from moving around. At this time, the two first pressing blocks 105 are squeezed toward the middle while holding the upper cover plate 101 to cover the end face of the lower cover plate 201, and finally the squeezing of the two first pressing blocks 105 is released.

[0035] Working principle: Before using the wiring harness, the second pressing block 108 is squeezed while adjusting the positions of the two second L-shaped plates 111. When using the wiring harness, the second pressing block 108 is squeezed while holding the raised end of the lower cover 201 and pushing it into the inside of the connection. When it cannot be pushed in further, release the squeezing of the second pressing block 108. When replacing the wire 3, the two first pressing blocks 105 are squeezed toward the middle while holding the upper cover 101 and moving it upward. At this time, the wire 3 can be removed from the surface of the second fixing block 202.

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