Description

Technical Field

[0001] This utility model relates to the field of cables, and specifically to a wire harness positioning clamp. Background Technology

[0002] A wire harness is a connecting cable used for signal transmission. It mainly consists of conductors and terminals at one end of the conductors. The connection between the terminals and the conductors needs to be wrapped with heat-shrink sleeves. These sleeves improve connection strength and prevent leakage. Currently, wire harness processing is primarily done on a thermoforming machine. The wire harness, with one end fitted with a terminal, is inserted into the machine and heated. The heat shrink sleeves on the terminals and conductors shrink to secure the terminals. However, the current heating method involves workers holding multiple wire harnesses and inserting the terminal-connected ends into a hot air blower. Holding multiple harnesses by hand easily leads to stacking, uneven heating, and incomplete shrinkage of the heat shrink sleeves on some conductors, causing the terminals to detach and affecting the quality of the wire harness.

[0003] Chinese utility model patent CN214958453U discloses a wire harness positioning clamp, including a base plate, two slide blocks fixedly installed on both sides of the upper surface of the base plate, and a sliding assembly slidably installed between the slide blocks. The two slide blocks are symmetrically arranged, and a slide groove is formed on the side wall of the slide block. Two guide grooves communicating with the slide groove are formed on the side wall of the slide groove. The two guide grooves are symmetrically arranged. The sliding assembly includes a slide plate and guide blocks installed on both sides of the slide plate. The two sides of the slide plate are embedded in the slide groove, and the guide blocks are slidably disposed inside the guide groove through the slide groove. Multiple clamping blocks are provided on the slide plate, and every two clamping blocks and the slide plate enclose a clamping groove. The multiple clamping grooves are of equal width.

[0004] The aforementioned technologies have the following drawbacks: the top of the clamping groove is open, and when the wire harness is placed in the clamping groove, during the heating process, the wire harness may easily come out of the clamping groove due to its own weight or accidental contact by the staff, affecting the installation of the heat shrink sleeve.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a wire harness positioning clamp, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a base plate 1, a cover plate 2, and a pressing assembly.

[0026] The base plate 1 is provided with a plurality of lower clamping grooves 11 at intervals.

[0027] The cover plate 2 is rotatably connected to the base plate 1. The cover plate 2 is provided with a plurality of upper clamping grooves 21 at intervals, and the plurality of upper clamping grooves 21 correspond to a plurality of lower clamping grooves 11.

[0028] The pressing component is fixed to the inner wall of the upper clamping groove 21 and has an elastic abutting end that abuts the wiring harness.

[0029] In use, open cover plate 2, and the operator can place the wire harness to be fitted with the heat shrink sleeve into the lower clamping groove 11. After placing the wire harness, rotate cover plate 2 to cover the base plate 1, so that the upper clamping groove 21 on cover plate 2 corresponds one-to-one with the lower clamping groove 11 on base plate 1, thereby making the upper clamping groove 21 and the lower clamping groove 11 fit tightly. The clamping component presses the wire harness firmly. The lower clamping groove 11, the upper clamping groove 21, and the clamping component work together to position and clamp the wire harness. Whether during normal placement of the wire harness or during subsequent operations that may involve heating, the upper clamping groove 21 and the lower clamping groove 11 can restrict the position of the wire harness and prevent it from moving randomly.

[0030] In this invention, the upper clamping groove 21 and the lower clamping groove 11 cooperate to form a closed clamping space. The wire harness is pressed tightly by the pressing component, which effectively prevents the wire harness from coming out of the clamping groove due to its own weight or accidental contact by the staff during heating and other operations. This ensures the smooth installation of the heat shrink sleeve and improves the stability and reliability of the installation.

[0031] To accommodate different cable harness sizes, please refer to [reference needed]. Figure 3 In a preferred embodiment, the pressing assembly includes a pressing block 22, a telescopic rod 23, and a spring 24. The end of the telescopic rod 23 is connected to the inner wall of the upper clamping groove 21. The pressing block 22 is connected to the end of the telescopic rod 23 away from the upper clamping groove 21. The spring 24 is sleeved on the telescopic rod 23. One end of the spring 24 abuts against the inner wall of the upper clamping groove 21, and the other end of the spring 24 abuts against the pressing block 22. The spring 24 is in a compressed state, and the spring 24 causes the pressing block 22 to tend to slide towards the lower clamping groove 11.

[0032] In use, the wire harness is placed in the lower clamping slot 11, and the cover plate 2 is rotated to align and close the upper clamping slot 21 with the lower clamping slot 11. The pressure block 22 will first contact the wire harness. Due to the continuous action of the elastic force of the spring 24, the pressure block 22 applies a downward pressure to the wire harness. At this time, the spring 24 is further compressed, generating greater elastic potential energy. As the cover plate 2 is fully closed, the elastic force of the spring 24 is evenly transmitted to the wire harness through the pressure block 22, tightly clamping the wire harness between the upper clamping slot 21 and the lower clamping slot 11. The elastic force generated by the spring 24 in its compressed state ensures that the pressure block 22 always applies a certain pressure to the wire harness. This pressure can adapt to wire harnesses of different thicknesses and shapes, avoiding uneven pressure that could cause the wire harness to shift.

[0033] To enable the telescopic pole 23 to extend and retract, please refer to... Figure 3In a preferred embodiment, the telescopic rod 23 includes a first rod body 231 and a second rod body 232. The end of the first rod body 231 is connected to the inner wall of the upper clamping groove 21. The second rod body 232 is slidably connected to the first rod body 231 along the length direction of the first rod body 231. The end of the second rod body 232 away from the first rod body 231 is connected to the pressure block 22.

[0034] In use, the sliding of the second rod 232 within the first rod 231, combined with the elastic force of the spring 24, allows the pressure block 22 to adaptively adjust its position and pressure according to the actual situation of the wire harness, thereby achieving reliable positioning and clamping of the wire harness and improving the performance and applicability of the wire harness positioning fixture.

[0035] To evenly distribute the pressure of the pressure block 22 and enhance the stability of the clamping, please refer to... Figure 3 In a preferred embodiment, the positioning fixture further includes a buffer layer 25, which is connected to the side of the pressure block 22 near the lower clamping groove 11. The buffer layer 25 is made of rubber and has a thickness of 1 mm.

[0036] During use, the pressure applied by the pressure block 22 during the clamping process is not completely uniformly distributed on the surface of the wire harness. The buffer layer 25 has a certain degree of elasticity and plasticity. When the pressure block 22 applies pressure to the wire harness, the buffer layer 25 will deform, which can evenly distribute the pressure applied by the pressure block 22 to a larger area of ​​the wire harness.

[0037] For easier rotation of cover plate 2, please refer to... Figure 1 In a preferred embodiment, the positioning clamp further includes a handle 26, which is connected to the cover plate 2.

[0038] In use, the handle 26 provides an easy gripping and force application point for the operator. By gripping the handle 26 and applying force, the cover plate 2 can be easily rotated.

[0039] To reduce the possibility of harness slippage, please refer to Figure 2 In a preferred embodiment, the positioning fixture further includes an anti-slip layer 12, which is connected to the lower clamping groove 11 and has an anti-slip texture.

[0040] During use, the presence of the anti-slip layer 12 significantly increases the friction between the lower clamping groove 11 and the wire harness, effectively preventing the wire harness from sliding in the clamping groove, avoiding installation deviations caused by wire harness displacement, and improving product quality.

[0041] To avoid overheating of the wiring harness during the use of the hot air blower, please refer to... Figure 3In a preferred embodiment, the positioning fixture further includes a plurality of heat dissipation channels 251, which are sequentially spaced on the buffer layer 25 along the width direction of the wire harness and extend along the length direction of the wire harness.

[0042] During use, the wire harness absorbs a large amount of heat and its temperature rises during the heating and installation of the heat shrink sleeve. The heat dissipation channels 251 are arranged at intervals along the width of the wire harness. The cool air from the outside flows in the heat dissipation channels 251, which removes the heat from the wire harness in time, reducing the temperature of the wire harness and improving the quality of the wire harness.

[0043] To further improve the heat dissipation effect of heat dissipation channel 251, please refer to... Figure 3 In a preferred embodiment, both the inlet and outlet of the heat dissipation channel 251 are open.

[0044] During use, the open inlet facilitates the smooth entry of cool outside air into the heat dissipation channel 251. As hot air rises and forms convection, the larger inlet opening area allows for a rapid and substantial influx of cool air, enhancing the convection force. Similarly, the open outlet allows hot air to escape without obstruction, accelerating the transfer of hot air from the buffer layer 25 to the external environment. This rapid air circulation within the channel increases the heat exchange rate per unit time, accelerating the reduction of the wiring harness temperature.

[0045] To secure the base plate 1 and the cover plate 2 together, please refer to... Figure 2 In a preferred embodiment, the positioning fixture further includes a fixing component 3, which includes a protrusion 31, a clamping block 32, and a plug rod 33. The protrusion 31 is connected to the cover plate 2, the clamping block 32 is connected to the base plate 1, the clamping block 32 is provided with a first insertion hole 34, the protrusion 31 is provided with a second insertion hole 35, and the plug rod 33 passes through the first insertion hole 34 and the second insertion hole 35.

[0046] In use, place the wire harness in the lower clamping groove 11 of the base plate 1, then rotate the cover plate 2 to align the upper clamping groove 21 on the cover plate 2 with the lower clamping groove 11. Simultaneously, bring the protrusion 31 connected to the cover plate 2 closer to the clamping block 32 connected to the base plate 1. Once the protrusion 31 is close to the clamping block 32 and the first insertion hole 34 and the second insertion hole 35 are aligned, insert the insertion rod 33 into the first insertion hole 34 and the second insertion hole 35. The insertion rod 33 connects the protrusion 31 and the clamping block 32, thus fixing the cover plate 2 and the base plate 1 together. The upper clamping groove 21 and the lower clamping groove 11 fit tightly, securely clamping the wire harness within. When it is necessary to remove the wire harness, pull the insertion rod 33 out of the first insertion hole 34 and the second insertion hole 35. After the insertion rod 33 is pulled out, the connection between the protrusion 31 and the clamping block 32 is released, and the cover plate 2 returns to a rotatable state. Rotate the cover plate 2 to open the clamp and remove the wire harness from the clamping groove.

[0047] To make it easier for the insertion rod 33 to slide into the first insertion hole 34 and the second insertion hole 35, please refer to... Figure 2 In a preferred embodiment, the end of the insertion rod 33 is spherical.

[0048] In use, the spherical end has a smaller contact area compared to the ordinary flat end of the plug 33. When inserting the plug 33 into the first socket 34 and the second socket 35, the spherical end is easier to align with the socket, reducing the resistance during insertion. Even if the socket position is slightly off, the plug 33 is naturally guided into the socket when it contacts the edge of the socket.

[0049] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of a wire harness positioning clamp according to the present invention is described in detail as follows: After opening the cover plate 2, the operator can place the wire harness to be fitted with a heat-shrink sleeve into the lower clamping groove 11. After placing the wire harness, rotate the cover plate 2 to cover the base plate 1, so that the upper clamping groove 21 on the cover plate 2 corresponds one-to-one with the lower clamping groove 11 on the base plate 1. This allows the upper and lower clamping grooves 21 to fit tightly together, and the clamping component presses the wire harness firmly. The lower clamping groove 11, the upper clamping groove 21, and the clamping component work together to position and clamp the wire harness. Whether during normal wire harness placement or during subsequent operations involving heating, the upper and lower clamping grooves 21 and 11 can restrict the position of the wire harness, preventing it from moving arbitrarily.

Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
