Abstract
Description
Technical Field
[0001] This utility model relates to a connector, and more particularly to a high-current connector. Background Technology
[0002] With the rapid development of new energy vehicles, industrial robots, energy storage systems and consumer electronics, especially the surge in market demand for new energy vehicles and robots, the demand for low-voltage high-current connectors has experienced explosive growth.
[0003] Despite surging demand, the high cost of existing solutions makes it difficult to meet OEMs' requirements for cost reduction and efficiency improvement. Existing high-current connectors also suffer from excessively high costs. Their complex and irregular shapes require high-precision molds, leading to high manufacturing costs. Furthermore, the assembly of multiple components, such as secondary locking rings and sealing rings, results in a significant proportion of labor costs. Therefore, simplifying connector structure and reducing production costs has become an urgent industry challenge.
[0004] This invention provides a high-current connector that solves the problems of traditional high-current connectors being heavy, complex in structure, and expensive to manufacture. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the high-current connector provided by this utility model has a more regular shape, and its structure is simplified and its weight is lighter, which greatly reduces the production cost and is conducive to promoting large-scale production.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0007] This utility model provides a high-current connector, comprising a first connecting component, a second connecting component, a first terminal, and a second terminal;
[0008] The first connecting component is generally a cuboid accommodating cavity with one end open, which is the first insertion part. The first connecting component has a first chamfer on one side, which extends from the first insertion part to the other end. The first chamfer is set on the long edge of one side of the first connecting component in the insertion direction.
[0009] The second connecting component is generally a cylindrical connecting part, with one end connected to the first connecting component as a second plug-in part, and the other end of the second connecting component is provided with a stop part. The first connecting component has a second chamfer on the same side after it is plugged into the second connecting component, and the second chamfer extends from the second plug-in part to the other end.
[0010] The first terminal is disposed inside the first connecting assembly. The first connecting assembly has a cylindrical mounting hole at the end away from the first plug-in part. The cylindrical mounting hole is tangent to the inside of the cuboid accommodating cavity and is used to install the first terminal. The first terminal can accommodate and lock the second terminal.
[0011] The second terminal is disposed inside the cylindrical connecting portion of the second connecting assembly;
[0012] Both the first connecting component and the second connecting component are insulators;
[0013] The first terminal and the second terminal each have an exposed opening at the end away from the first plug-in portion and the second plug-in portion, respectively.
[0014] In the high-current connector described above, the first connecting component and the second connecting component are provided with a positioning frustum at the end away from the insertion / removal point for positioning and installing the first terminal and the second terminal, and a circular hole plug is provided in the middle of the positioning frustum.
[0015] In the high-current connector described above, the first terminal and the second terminal are further provided with fixing holes, which are provided at the connection points of the first connecting component and the second connecting component with the first terminal and the second terminal, respectively. A connecting post is also provided at the connection point, which extends out of the connecting component and passes through the fixing hole to connect to the circular hole plug.
[0016] As described above, in a high-current connector, there are two cylindrical connecting parts, and a connecting plate is provided between the two cylindrical connecting parts for fixing the two cylindrical connecting parts together.
[0017] In the high-current connector described above, the cylindrical mounting holes have the same cross-sectional size as the cylindrical connecting portion, and a connecting block is provided between the cylindrical mounting holes. The connecting block has the same thickness and width as the connecting plate.
[0018] In the high-current connector described above, after the first connecting component and the second connecting component are inserted, a central through hole is also formed. The central through hole is symmetrically distributed with the connecting plate and the connecting block as the axis of symmetry, which is used to reduce the weight of the connector.
[0019] In the high-current connector described above, the first chamfer and the second chamfer are respectively disposed on the left and right ends of the same side of the first connecting component and the second connecting component, and the distribution of the first chamfer and the second chamfer is consistent with the arrangement direction of the first terminal and the second terminal, which is used to distinguish the positive and negative directions when the connector is plugged in.
[0020] In a high-current connector as described above, the stop portion is disposed at the end of the cylindrical connecting portion away from the insertion / removal end and is tangentially disposed to the periphery of the cylindrical connecting portion. The stop portion and the opening form a limit, restricting the insertion / removal degree of the connector.
[0021] As described above, a high-current connector has grooves at both ends of the first and second connecting components, respectively located at the four corners of the upper and lower surfaces of the connector, which can be fixedly connected to other units.
[0022] As described above, a high-current connector has protrusions on the outside of the first connecting component and the second connecting component to increase friction during insertion and removal. The protrusions are strip-shaped and are respectively disposed on both sides of the first connecting component and the second connecting component away from the first insertion and removal portion and the second insertion and removal portion.
[0023] The beneficial effects of this utility model are as follows: The high-current connector includes first and second connecting components, first and second terminals. The first connecting component is generally a cuboid cavity with one end open. The second connecting component is a cylindrical connecting part with a stop portion on the non-plugging part. The first connecting component and the second connecting component have chamfered corners on the same side after plugging in. The first terminal is located in a cylindrical mounting hole within the first connecting component. The second terminal is located within the cylindrical connecting part of the second connecting component. The high-current connector provided by this utility model has a relatively regular shape, a simplified structure, and a lighter weight, which greatly reduces production costs and facilitates large-scale production.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it.
[0038] like Figure 1 As shown, this utility model provides a high-current connector, which includes a first connecting component 1, a second connecting component 2, a first terminal 4, and a second terminal 5.
[0039] The first connecting component 1 is generally a cuboid accommodating cavity with one end open, which is the first insertion / extraction part 11. The first connecting component 1 has a first chamfer 12 on one side, which extends from the first insertion / extraction part 11 to the other end. The first chamfer 12 is disposed on the long edge of the first connecting component 1 in the insertion / extraction direction.
[0040] Furthermore, the second connecting component 2 is generally a cylindrical connecting part 21, with one end connected to the first connecting component 1 being a second plug-in part 22, and the other end of the second connecting component 2 being provided with a stop part 24. The first connecting component 1 has a second chamfer 23 on the same side after being plugged into the second connecting component 2, and the second chamfer 23 extends from the second plug-in part 22 to the other end.
[0041] like Figure 5As shown, when the high-current connector is in use, if the first connecting component 1 is inserted into the second connecting component 2, the rectangular receiving cavity of the first connecting component 1 connects with the cylindrical connecting portion 21 of the second connecting component 2. Constrained by the first chamfer 12 and the second chamfer 23, the first connecting component 1 and the second connecting component 2 are connected according to their designated positive and negative terminals. Furthermore, because the second connecting component 2 is provided with a stop portion 24, the opening of the first connecting component 1 is blocked by the stop portion 24, thus completing the connection between the first connecting component 1 and the second connecting component 2. It can be seen that the high-current connector provided by this utility model has a relatively regular shape, a simple design, and a simple structure, which is beneficial for production and assembly.
[0042] like Figure 2 and Figure 3 As shown, further, the first terminal 4 is disposed inside the first connecting assembly 1, and the first connecting assembly 1 has a cylindrical mounting hole 13 at the end away from the first plug-in portion 11 for mounting the first terminal 4.
[0043] like Figure 4 As shown, the second terminal 5 is further disposed inside the cylindrical connecting portion 21 of the second connecting component 2, and both the first connecting component 1 and the second connecting component 2 are insulators.
[0044] After the first connecting component 1 and the second connecting component are connected, the first terminal 4 and the second terminal 5 inside the first connecting component 1 and the second connecting component 2 are also electrically connected.
[0045] Furthermore, the first terminal 4 and the second terminal 5 each have an exposed opening at the end away from the first plug-in portion 11 and the second plug-in portion 22, which facilitates subsequent electrical connection with other units.
[0046] like Figure 4 As shown, further, there are two cylindrical connecting parts 21, and the second connecting assembly 2 also includes a connecting plate 25 disposed between the two cylindrical connecting parts 21 for fixing the two cylindrical connecting parts 21 together.
[0047] Furthermore, the cylindrical mounting hole 13 has the same cross-sectional size as the cylindrical connecting part 21, and a connecting block 14 is provided between the cylindrical mounting holes 13, the connecting block 14 having the same thickness as the connecting plate 25.
[0048] Furthermore, after the first connecting component 1 and the second connecting component 2 are inserted, a central through hole 31 is formed, which is symmetrically distributed with the connecting plate 25 and the connecting block 14 as the axis of symmetry.
[0049] like Figure 6 As shown, since the first connecting component 1 has a cylindrical mounting hole 13 at one end of the cuboid cavity away from the first insertion part 11, and the cylindrical mounting hole 13 has the same size as the outer cross section of the cylindrical connecting part 21, and the connecting block 14 has the same thickness as the connecting plate 25, after the high current connector is inserted, the high current connector provided by this utility model forms two symmetrical central through holes 31 with axial symmetry, which can save the manufacturing raw materials of the connector assembly, thereby saving costs and also achieving the effect of reducing the weight of the connector.
[0050] Furthermore, the first chamfer 12 and the second chamfer 23 are respectively disposed on the left and right ends of the same side of the first connecting component 1 and the second connecting component 2, and the distribution of the first chamfer 12 and the second chamfer 23 is consistent with the arrangement direction of the first terminal 4 and the second terminal 5. The first chamfer 12 and the second chamfer 23 can be used to quickly distinguish the positive and negative poles when the connector is plugged in and unplugged, so as to avoid the user connecting in the opposite direction.
[0051] Furthermore, the first connecting component 1 and the second connecting component 2 are provided with a positioning frustum 32 at the end away from the plug-in point for positioning and installing the first terminal 4 and the second terminal 5. The positioning frustum 32 is provided with a circular hole plug 33 in the middle. The circular hole plug 33 can seal the end of the first terminal 4 and the second terminal 5 away from the plug-in point to prevent foreign objects from entering during use.
[0052] In addition, such as Figure 7 As shown, the first terminal 4 and the second terminal 5 are also provided with fixing holes 36, which are respectively provided at the connection points with the first connecting component 1 and the second connecting component 2. The first connecting component 1 and the second connecting component 2 are also provided with connecting posts 37 at the connection points of the first terminal 4 and the second terminal 5, respectively. The connecting posts 37 extend from the connecting components, pass through the fixing holes 36 and connect to the circular hole plug 33. The connecting posts 37 fix the first terminal 4 and the second terminal 5 between the positioning frustum 32 and the circular hole plug 33 to prevent the terminals from being placed, rotated or moved back and forth.
[0053] Furthermore, the stop portion 24 is provided at the end of the cylindrical connecting portion 21 away from the insertion / removal end, and is provided around the cylindrical connecting portion 21. The stop portion 24 and the opening form a limit, restricting the degree of insertion / removal of the connector.
[0054] Furthermore, grooves 34 are provided at both ends of the first connecting component 1 and the second connecting component 2, respectively located at the four corners above and below the connector, to facilitate fixed connection with waterproof or other units.
[0055] Furthermore, protrusions 35 are provided on the outside of the first connecting component 1 and the second connecting component 2 to increase friction during connection and facilitate insertion and removal.
[0056] Furthermore, the protrusions 35 are strip-shaped and are respectively disposed on both sides of the first connecting component 1 and the second connecting component 2 away from the first plug-in part 11 and the second plug-in part 22.
[0057] The high-current connector provided by this utility model has a relatively regular shape, and its structure is simplified and its weight is lighter, which greatly reduces manufacturing costs and manual assembly costs, and is conducive to promoting large-scale production.
