Description

Technical Field

[0001] This invention relates to a positioning structure, and more particularly to a liquid cooling cable clamp and a charging gun. Background Technology

[0002] The charging gun contains liquid cooling pipes and cables. The liquid cooling pipes deliver coolant, while the cables deliver current. To improve the stability of the internal structure of the charging gun, the liquid cooling pipes and cables are usually bundled and positioned during manufacturing. However, current technologies use a single method to fix the liquid cooling pipes and cables, which cannot simultaneously meet the positioning requirements. For example, a simple, forceful clamping can flatten the liquid cooling pipes, affecting coolant flow, while a looser clamping can cause the cables to loosen, leading to bending or damage. Summary of the Invention

[0003] The purpose of this invention is to provide a cable clamp and charging gun for liquid cooling, so as to distinguish and position the cable and the liquid cooling pipe, and ensure the normal flow of coolant in the liquid cooling pipe while ensuring the cable is clamped.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A cable clamp for liquid cooling, comprising:

[0006] At least one first clamping block, wherein the first clamping block is provided with a plurality of through holes and a plurality of first clamping grooves;

[0007] At least one second clamping block, wherein the first clamping groove and the adjacent second clamping block form a clamping hole; the first clamping block and the second clamping block are connected to each other by a connector, and the gap between the first clamping block and the second clamping block can be adjusted by the connector.

[0008] As an optional solution for a liquid cooling cable clamp, the side of the through hole is open; the arc of the opening is greater than 270 degrees.

[0009] As an alternative solution for a liquid-cooled cable clamp, the opening is connected to the first clamping groove.

[0010] As an alternative solution for liquid-cooled cable clamps, the first clamping groove is an arc-shaped groove, and the second clamping block has an arc-shaped second clamping groove at a position corresponding to the first clamping groove. The second clamping groove and the first clamping groove can form a circular clamping hole.

[0011] As an optional solution for liquid cooling cable clamps, the first clamping block is provided with a limiting block, and the second clamping block is provided with a limiting groove at a position corresponding to the limiting block, and the limiting block can be inserted into the limiting groove.

[0012] As an alternative solution for liquid-cooled cable clamps, the limiting block is formed by a spaced structure of two adjacent first clamping slots.

[0013] As an alternative solution for a liquid cooling cable clamp, the connector is a first screw, which passes through a first insertion hole that penetrates the first clamping block and the second clamping block, and is tightened and fixed by nuts at both ends.

[0014] A charging gun includes a cable and a liquid cooling tube, and a sleeve wrapped around the cable and the liquid cooling tube. The cable, the liquid cooling tube and the sleeve are all located inside the housing of the charging gun. The charging gun includes a liquid cooling cable clamp, the cable passes through the clamp hole and the liquid cooling tube passes through the tube hole.

[0015] As an optional solution for the charging gun, the charging gun also includes a secondary clamp, which is fixed to the outside of the sleeve. A stop is provided inside the housing, and the secondary clamp is inserted between two of the stop blocks. The axial position of the secondary clamp is restricted by the stop blocks.

[0016] As an optional solution for the charging gun, the secondary clamp is a clamp.

[0017] The beneficial effects of this invention are:

[0018] 1. The liquid cooling cable clamp and charging gun provided by the present invention clamp and position the cable through the clamping hole, and position the liquid cooling pipe through the through hole opened on the first clamping block, so as to realize the differentiated positioning of the charging gun cable and the liquid cooling pipe, and ensure the normal flow of coolant in the liquid cooling pipe while ensuring the cable is clamped.

[0019] 2. The liquid cooling cable clamp and charging gun provided by the present invention can adjust the gap between the first clamping block and the second clamping block through the connector to obtain the required clamping force, and the clamp can be adapted to cable positioning within a certain size range by adjusting the clamping force.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0028] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0031] This embodiment provides a cable clamp and charging gun for liquid cooling, which are used to position the cable and liquid cooling pipe in the charging gun respectively, so as to solve the problem that in the prior art, the fixing method of liquid cooling pipe and cable is singular and cannot meet the positioning requirements of liquid cooling pipe and cable, resulting in loose cable or poor flow of coolant in liquid cooling pipe.

[0032] Figure 1 This is a front view of the liquid cooling cable clamp 100 provided by the present invention, with reference to... Figure 1 As shown, the liquid cooling cable clamp 100 provided in this embodiment includes at least one first clamping block 110 and at least one second clamping block 120. The first clamping block 110 has a plurality of through holes 111 and a plurality of first clamping grooves 112. The first clamping grooves 112 and the connected second clamping blocks 120 form clamping holes 130. The first clamping blocks 110 and the second clamping blocks 120 are connected to each other by a connector, and the gap between the first clamping blocks 110 and the second clamping blocks 120 can be adjusted by the connector.

[0033] The liquid cooling cable clamp 100 provided in this embodiment clamps and positions the cable 400 in the clamping hole 130 through the first clamping block 110 and the second clamping block 120, ensuring the stability of the cable 400's positioning. The liquid cooling pipe 300 passes through the through hole 111 opened on the second clamping block 120, ensuring the normal flow of coolant. At the same time, during use, the gap between the first clamping block 110 and the second clamping block 120 can be adjusted through the connector to obtain the required clamping force, and the clamp can be adjusted to be suitable for positioning cables 400 within a certain size range.

[0034] In this embodiment, the number of the first clamping block 110 and the second clamping block 120, as well as the number and size of the through hole 111 and the first clamping groove 112, can be adjusted as needed. For example, in this embodiment... Figure 1 The liquid cooling cable clamp 100 shown includes a first clamping block 110 and two second clamping blocks 120. The two second clamping blocks 120 are symmetrically arranged on both sides of the first clamping block 110. The first clamping block 110 is symmetrically provided with two through holes 111 and ten first clamping grooves 112.

[0035] Continue to refer to Figure 1As shown, to facilitate the installation of the liquid cooling pipe 300, in this embodiment, the side of the through hole 111 is open. During installation, the liquid cooling pipe 300 can be inserted into the through hole 111 through the opening, eliminating the need for through-hole installation. Preferably, to maintain the original shape of the liquid cooling pipe 300 during use and ensure smooth coolant flow, the curvature of the opening is greater than 270 degrees. During installation, the liquid cooling pipe 300 can be flexibly deformed and inserted into the opening. Furthermore, to save space, in this embodiment, the opening of the through hole 111 is connected to the first clamping groove 112.

[0036] In this embodiment, the first clamping groove 112 is an arc-shaped groove, and the second clamping block 120 is provided with an arc-shaped second clamping groove 121 at the position corresponding to the first clamping groove 112. This design enables the second clamping groove 121 and the first clamping groove 112 to form a circular wire clamping hole 130, so as to match the shape of the cable 400 and avoid the cable 400 from being damaged due to severe deformation.

[0037] Furthermore, to prevent misalignment of the first clamping groove 112 and the second clamping groove 121, in this embodiment, a limiting block 113 is provided on the first pressing block 110, and a limiting groove 122 is provided on the second pressing block 120 at a position corresponding to the limiting block 113. The limiting block 113 can be inserted into the limiting groove 122 to limit the position of the first pressing block 110 and the second pressing block 120, ensuring that the positions of the first clamping groove 112 and the second clamping groove 121 can correspond to each other.

[0038] As an optional solution for the liquid-cooled cable clamp 100, in this embodiment, the limiting block 113 is formed by the spaced structure of two adjacent first clamping grooves 112, thus making full use of the structure; at the same time, the limiting groove 122 can be set as a trapezoidal groove to facilitate the entry of the limiting block 113. Of course, in some other embodiments, the limiting block 113 can also be set in other parts of the first clamping block 110.

[0039] Figure 2 This is a schematic diagram of the overall structure of the liquid cooling cable clamp 100 and the secondary clamp 200 provided by the present invention. Figure 3 An exploded view of the liquid cooling cable clamp 100 and the secondary clamp 200 provided by the present invention, with reference to... Figure 2 and Figure 3 As shown, in this embodiment, the connector is a first screw 150. The first screw 150 passes through the first insertion hole 140 of the first clamping block 110 and the second clamping block 120, and is tightened and fixed by nuts provided at both ends. In use, the gap between the first clamping block 110 and the second clamping block 120 can be adjusted by loosening or tightening the nuts, thereby changing the clamping force on the cable 400.

[0040] To reduce the weight of the liquid-cooled cable clamp 100, in this embodiment, the first clamping block 110 has a weight-reducing hole 114. Specifically, in this embodiment, the weight-reducing hole 114 is located at the position of the first insertion hole 140. Furthermore, in this embodiment, the second clamping block 120 has multiple grooves, and reinforcing ribs are formed between adjacent grooves to ensure the mechanical strength of the second clamping block 120, thereby reducing the weight ratio of unnecessary structures in the liquid-cooled cable clamp 100 and keeping the liquid-cooled cable clamp 100 lightweight.

[0041] Continue to refer to Figure 2 and Figure 3 As shown, this embodiment also provides a charging gun, which includes a cable 400 and a liquid cooling pipe 300, and a sleeve 500 wrapped around the cable 400 and the liquid cooling pipe 300. The cable 400, the liquid cooling pipe 300 and the sleeve 500 are all located inside the outer shell of the charging gun. The charging gun includes a liquid cooling cable clamp 100. The cable 400 passes through the clamping hole 130 and is clamped in the clamping hole 130. The liquid cooling pipe 300 passes through the through hole 111. The through hole 111 limits the circumferential position of the liquid cooling pipe 300, thereby distinguishing and positioning the cable 400 and the liquid cooling pipe 300 of the charging gun. While ensuring that the cable 400 is clamped, the normal flow of coolant in the liquid cooling pipe 300 can also be ensured.

[0042] Furthermore, in this embodiment, the charging gun also includes a secondary clamp 200, which is fixed to the outside of the sleeve 500. A stop is provided inside the charging gun's housing, and the secondary clamp 200 is inserted between two stopes. The secondary clamp 200 restricts its axial position through the stopes, thereby preventing axial displacement of the cable 400 and the liquid cooling pipe 300, and preventing damage to the connection between the cable 400 and the liquid cooling pipe 300 inside the charging gun due to axial tension. Similarly, to ensure the stability of the liquid cooling cable clamp 100, stopes can also be provided on both sides of the charging gun housing on the liquid cooling cable clamp 100 to limit its position.

[0043] Specifically, in this embodiment, the secondary clamp 200 is a clamp, and the sleeve 500 passes through the clamp. The two ends of the clamp are provided with second insertion holes 210 that are positioned opposite each other. The clamp is clamped and fixed to the outside of the sleeve 500 by a second screw 220 that passes through the second insertion hole 210 and a nut that is tightened to the second screw 220.

[0044] Note: For fixing methods not explicitly mentioned in the text, common fixing and connection methods such as threaded connection, welding or bonding can be used as needed.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
