Description

Technical Field

[0001] This utility model relates to the field of cable production tools technology, and in particular to a cable production docking device. Background Technology

[0002] Cables are carriers of electrical power and a crucial connecting material in daily life. They are typically rope-like structures made of several or groups of conductors (at least two conductors per group), twisted together. Each group of conductors is insulated from the others and often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. During cable manufacturing, it is often necessary to connect two strands of cable for product or testing purposes. Chinese patent document CN 214897823 U describes a cable connection device, but its application is limited due to the size limitations of the clamping slot. Chinese patent document CN 109119205 A describes another cable connection device, which also suffers from the same drawbacks: inaccurate positioning and cumbersome operation. Therefore, improvements are needed. Utility Model Content

[0003] This utility model provides a cable splicing device for cable production, which solves the technical problems of inaccurate cable splicing positioning, cumbersome operation, and inability to adapt to different diameters.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cable production docking device, including two fixed seats arranged in parallel on the top of the workbench, a semi-circular clamping plate slidably provided on the fixed seats, the semi-circular clamping plate being connected to the fixed seats through a locking unit, the connection between the fixed seats and the semi-circular clamping plate forming a clamping space for fixing the cable, and the inner sides of the fixed seats and the semi-circular clamping plate respectively abutting against the outer wall of the cable through multiple contact plates.

[0005] In the preferred embodiment, the fixing base includes a base plate and a boss. C-shaped baffles are provided on both sides of the boss. The locking unit includes a straight plate and a round rod. The round rod passes through the C-shaped baffles. Ear plates are provided on both sides of the semi-ring clamp. Multiple second locking teeth and first locking teeth are provided on the outer sides of the straight plate and the ear plates, and the second locking teeth and the first locking teeth engage.

[0006] In a preferred embodiment, the top of the workbench is provided with multiple first threaded holes, the bottom of the workbench is supported by multiple legs, and the base plate is provided with multiple third through holes, with screws passing through the third through holes and the first threaded holes.

[0007] In the preferred embodiment, the boss has an arc-shaped groove in the middle, and second threaded holes are provided on both sides of the arc-shaped groove. Multiple third threaded holes are provided through the semi-ring clamp, and the contact plate is located in the second threaded holes and the third threaded holes.

[0008] In a preferred embodiment, a groove is provided on one side of the contact plate, a top block is inserted into the groove, and a second threaded rod is provided at the end of the top block. The second threaded rod is located in the second threaded hole and the third threaded hole.

[0009] In the preferred embodiment, the C-shaped baffle is provided with a first through hole and a first threaded rod on both sides, the round rod is inserted into the first through hole, a second spring is sleeved on the round rod, the support plate is sleeved in the first threaded rod and the round rod, and the first threaded rod is also provided with a locking sleeve for adjusting the position of the support plate.

[0010] In the preferred embodiment, the boss is provided with a groove at the bottom of the C-shaped baffle, and a second through hole is provided in the groove. A guide rod is provided at the bottom of the ear plate, and a first spring is sleeved on the guide rod. The guide rod passes through the second through hole, and the first spring abuts against the groove.

[0011] In the preferred embodiment, the second spring rests against the inner sides of the straight plate and the support plate on both sides, the support plate has a fifth through hole in the middle, and a fourth through hole on one side of the fifth through hole, and the first threaded rod and the round rod pass through the fifth through hole and the fourth through hole respectively.

[0012] The beneficial effects of this utility model are as follows: By setting two fixed seats in parallel on the workbench, a semi-circular clamping plate is slidably mounted on the fixed seats, and multiple contact plates are provided between the semi-circular clamping plate and the fixed seats. The contact plates abut against the outer wall of the cable, and the two contact plates on the upper and lower sides of the cable respectively form a V-shaped limit, thereby ensuring the positioning of the cable.

Detailed Implementation

[0026] like Figure 1-5 In a cable production docking device, there are two fixed seats 2 arranged in parallel on the top of a workbench 1. A semi-circular clamping plate 3 is slidably arranged on the fixed seat 2. The semi-circular clamping plate 3 is connected to the fixed seat 2 through a locking unit 8. The connection between the fixed seat 2 and the semi-circular clamping plate 3 forms a clamping space 4 for fixing the cable 7. The inner sides of the fixed seat 2 and the semi-circular clamping plate 3 respectively abut against the outer wall of the cable 7 through multiple contact plates 5.

[0027] Since the outer diameter of cable 7 is a relatively smooth plastic insulation layer, and the outer diameter of different models of cable 7 varies, the size of clamping space 4 is changed by adjusting the distance between the semi-ring clamp 3 and the fixing seat 2. When cable 7 passes through clamping space 4, multiple contact plates 5 set inside clamping space 4 cooperate with each other. Two oppositely set contact plates 5 near the fixing seat 2 form a V-shaped structure to support and constrain cable 7. At this time, the semi-ring clamp 3 is pressed down further, and the locking unit 8 locks the semi-ring clamp 3 on the fixing seat 2. The operation is convenient, the locking is firm, and the overall fixing effect is guaranteed.

[0028] like Figure 11 In the preferred embodiment, the fixing base 2 includes a base plate 201 and a boss 202. C-shaped baffles 203 are provided on both sides of the boss 202. The locking unit 8 includes a straight plate 801 and a round rod 803. The round rod 803 passes through the C-shaped baffle 203. Ear plates 301 are provided on both sides of the semi-ring clamping plate 3. Multiple second locking teeth 802 are provided on the outer sides of the straight plate 801 and the ear plates 301, which engage with the first locking teeth 302.

[0029] The distance between the inner walls of the two C-shaped baffles 203 and the distance between the outer walls of the two ear plates are equal, thus ensuring the stability of the semi-ring clamp 3 during its up-and-down movement and preventing misalignment. When the semi-ring clamp 3 is pressed down, the first locking tooth 302 on the ear plate 301 pushes the straight plate 801 to move to both sides by pressing the second locking tooth 802 on the straight plate 801. Since the first locking tooth 302 and the second locking tooth 802 are locked together, when the semi-ring clamp 3 moves to the designed position, the ear plate 301 on each side is locked by the two straight plates 801. At this time, the semi-ring clamp 3 is completely connected to the fixed seat 2, and the cable 7 in the clamping space 4 is stably fixed.

[0030] like Figure 5 In the preferred embodiment, the top of the workbench 1 is provided with a plurality of first threaded holes 101, the bottom of the workbench 1 is supported by a plurality of support legs 102, and a plurality of third through holes 209 are provided through the bottom plate 201. Screws 6 are inserted into the third through holes 209 and the first threaded holes 101.

[0031] The installation between the fixed base 2 and the workbench 1 is convenient. The distance between the two fixed bases 2 can be adjusted as needed to meet the space and distance requirements when the cables 7 on both sides are connected. It is easy to operate and has a good effect. At the same time, the support leg 102 can also be adjusted according to the height of the ground to ensure that the fixed base 2 at the top is in a horizontal state, and the overall use accuracy is higher.

[0032] In the preferred embodiment, the boss 202 has an arc-shaped groove 210 in the middle, and second threaded holes 207 are provided on both sides of the arc-shaped groove 210. Multiple third threaded holes 304 are provided through the semi-ring clamping plate 3, and the contact plate 5 is located in the second threaded holes 207 and the third threaded holes 304.

[0033] The arc groove 210 serves as a buffer space. When the adjustment range of the contact plate 5 is insufficient to ensure the constraint and fixation of the cable 7, the two contact plates 5 located on the fixed base 2 can be removed. At this time, the bottom of the cable 7 is attached to the arc groove 210. Therefore, the number and position of the contact plates 5 can be changed in a timely manner according to the needs of use to ensure that the cable 7 has a sufficiently stable clamping function.

[0034] In a preferred embodiment, a groove 501 is provided on one side of the contact plate 5, a top block 502 is inserted into the groove 501, and a second threaded rod 503 is provided at the end of the top block 502. The second threaded rod 503 is located in the second threaded hole 207 and the third threaded hole 304.

[0035] The length of the contact plate 5 is greater than the width of the arc groove 210 and the semi-circular clamping plate 3. When it is necessary to adjust the distance between the contact plate 5 and the center of the clamping space 4, the contact plate 5 is removed from the top block 502, and then the length of the second threaded rod 503 is adjusted. After reaching the design position, the contact plate 5 is reinserted into the top block 502. The central axis of the contact plate 5 is kept parallel to the central axis of the cable 7, thereby ensuring that the contact plate 5 and the outer wall of the cable 7 are fully fitted.

[0036] like Figure 6-10 In the preferred embodiment, the C-shaped baffle 203 is provided with a first through hole 204 and a first threaded rod 205 on both sides, a round rod 803 is inserted into the first through hole 204, a second spring 805 is sleeved on the round rod 803, a support plate 804 is sleeved in the first threaded rod 205 and the round rod 803, and a locking sleeve 808 for adjusting the position of the support plate 804 is also provided on the first threaded rod 205.

[0037] The second spring 805 passes through the first through hole 204. When the semi-ring clamp 3 is pressed down, the first locking tooth 302 pushes the straight plate 801 to both sides. Then, because the support plate 804 and the locking sleeve 808 are fixed on the outside of the C-shaped baffle 203, the second spring 805 is fully compressed. When the semi-ring clamp 3 is pressed down to the designed position, the second locking tooth 802 and the first locking tooth 302 cooperate to lock. The second spring 805 pushes the straight plate 801 to fix the ear plate 301. When the cable 7 is completed, the locking sleeve 808 is screwed outward. The second spring 805 is relieved and the round rod 803 is pulled outward. The ear plate 301 is released from the locked state, and the semi-ring clamp 3 is moved up. According to the needs of use, the restriction on the top of the cable 7 can be completely opened. After the cable 7 is removed, the semi-ring clamp 3 is reinstalled on the fixed base 2. The overall operation is very simple, and no parts will fall off during the whole process. The effect is good.

[0038] In the preferred embodiment, the boss 202 is provided with a groove 206 at the bottom of the C-shaped baffle 203, and a second through hole 208 is provided in the groove 206. The bottom of the ear plate 301 is provided with a guide rod 303, and a first spring 305 is sleeved on the guide rod 303. The guide rod 303 passes through the second through hole 208, and the first spring 305 abuts against the groove 206.

[0039] To further improve the control of the locking state of the semi-ring clamp 3, the groove 206, as a clearance space 206, provides sufficient clamping area for the ear plate 301. At the same time, the guide rod 303 plays a positioning and guiding role. The overall adjustment accuracy is high. The first spring 305 provides reverse support force to the semi-ring clamp 3. When the ear plate 301 and the straight plate 801 are locked, the locking effect of the first locking tooth 302 and the second locking tooth 802 is better, and the first spring 305 eliminates the gap.

[0040] In the preferred embodiment, the second spring 805 abuts against the inner sides of the straight plate 801 and the support plate 804 on both sides respectively. The support plate 804 has a fifth through hole 807 in the middle and a fourth through hole 806 on one side of the fifth through hole 807. The first threaded rod 205 and the round rod 803 pass through the fifth through hole 807 and the fourth through hole 806 respectively.

[0041] In order to ensure a better overall locking effect during use, two fourth through holes 806 are provided on the support plate 804, and two round rods 803 are provided on the outer side of the support plate 801. This results in better overall stability, stronger locking force, and sufficient support.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
