Description

Technical Field

[0001] This invention relates to the field of cable technology, and more particularly to a branching assembly and a pin device. Background Technology

[0002] Cables typically consist of several conductors encased in an outer sheath, with each group of conductors insulated from the others. During use, the outer sheath at the cable ends needs to be stripped off, and the exposed conductors are then connected to electrical components. However, because the cable ends are not covered by an outer sheath, the cable's end structure is loose, its strength is reduced, and it is prone to bending, which can lead to the insulation of the conductors breaking and causing safety accidents.

[0003] To solve the above problems, after removing the cable's outer sheath, pins are usually inserted between the cable's conductors to increase the strength of the cable ends. However, inserting the pins requires bending the conductors outwards and using a clamping head to insert the pins. Because the conductors themselves have a certain degree of rigidity, they are prone to springing back after being bent, causing them to be crushed by the clamping head.

[0004] To address the aforementioned issues, a branching assembly and pin connector need to be developed to resolve them. Summary of the Invention

[0005] The purpose of this invention is to provide a wire splitter assembly and a pin device that can fix the wire after the cable end is bent, prevent the wire from springing back, and thus avoid the wire being crushed by the pressure head.

[0010] In some embodiments, the dividing groove includes a first sidewall and a second sidewall, the first sidewall and the second sidewall of the plurality of dividing grooves are in the same relative position, the plurality of first sidewalls are inclined outward to form a guide surface, the plurality of pressing portions are provided with a sliding surface, when the cover member is closed on the dividing ring, the sliding surface slides on the guide surface to drive the cover member to rotate relative to the dividing ring, so that the pressing portion moves closer to or away from the second sidewall.

[0011] In some embodiments, the angle α between the guide surface and the radial surface of the dividing ring gradually increases along the direction of entering the dividing groove.

[0012] In some embodiments, the branching assembly further includes a fixing structure, through which the branching ring and the cover are fixedly connected.

[0014] In some embodiments, the first adsorption element is embedded in the pressing portion, and the second adsorption element is embedded in the second sidewall.

[0015] In some embodiments, the diameter of the through hole is smaller than the diameter of the wire hole.

[0016] In some embodiments, the body abuts circumferentially against the inner wall of the wire hole.

[0017] A pin connector, including the aforementioned splitter assembly, further includes:

[0018] A fixing platform is provided on which the cable distribution assembly is disposed. The fixing platform is used to fix the cable and allow the cable to pass through the cable through hole.

[0019] A pressure head is vertically movable above the fixed platform, and the pressure head can abut against the pin and insert the pin into the cable.

[0020] In some embodiments, the pin device further includes a cover plate, and a fixing groove is provided on the side of the fixing platform in a vertical direction. The cable is disposed in the fixing groove, and the cover plate can cover the fixing platform and block the fixing groove.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a cable splitter assembly and a pin device. After one end of the cable passes through the cable guide hole, the exposed multiple wires are bent outwards and placed into the cable splitter grooves. The wires are then fixed by a cover, so that the wires can be fixed by the receiving hole formed by the crimping part and the corresponding cable splitter groove.

[0023] This cable splitter assembly can secure the bent wires at the cable ends, preventing them from springing back and thus avoiding damage to the wires from the pressure head. Attached Figure Description

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] A cable consists of an outer sheath and multiple conductors arranged in a circle and secured by the outer sheath. When in use, the outer sheath needs to be removed from the ends of the cable to expose the conductors. Because the ends are not covered by the outer sheath, the cable's end structure becomes loose, its strength decreases, and it becomes prone to bending, which can cause the conductor insulation to crack and lead to safety accidents.

[0040] To address these issues, after removing the cable's outer sheath, pins are typically inserted between the cable's conductors to increase strength and prevent bending at the cable ends. However, inserting the pins requires bending the conductors outwards to create space, and then using a pressure head to force the pins in. Because the conductors themselves have a certain degree of rigidity, they tend to spring back after bending, and the high bends are easily damaged by the pressure head.

[0041] This embodiment provides a pin insertion device for inserting pins 100 between the wires 202 of a cable 200. For example... Figure 1 and Figure 2 As shown, the pin assembly includes a splitter assembly 1, a mounting platform 2, and a pressure head 3. The splitter assembly 1 is mounted on the mounting platform 2, which is used to fix the cable 200 and allow the cable 200 to pass through the cable hole 111. The pressure head 3 is vertically movable above the mounting platform 2 and can abut against the pin 100 and insert the pin 100 into the cable 200.

[0042] The splitter assembly 1 can bend and fix the exposed wires 202 at the end of the cable 200 outwards. The pressure head 3 can descend and abut against the pin 100, so that the pin 100 is inserted between the multiple wires 202 of the cable 200. The fixing platform 2 can fix the splitter assembly 1 and the cable 200, so that the relative position between the splitter assembly 1 and the cable 200 remains unchanged, preventing the position of the wires 202 from changing during the insertion of the pin 100, which would cause the wires 202 to be damaged by the pin 100 or the pressure head 3.

[0043] Specifically, the pin insertion device also includes a slider 7 and a driving component. The slider 7 is slidably mounted on the fixed platform 2 in a vertical direction and is fixedly connected to the pressure head 3. The driving component is configured to drive the slider 7 to slide. By using the driving component to drive the slider 7 to slide, the pressure head 3 can insert the pin 100 into the multiple wires 202 of the cable 200. The driving component ensures that the driving force of the pressure head 3 on the pin 100 remains stable during the insertion process. Specifically, the driving component is an electric cylinder or a pneumatic cylinder.

[0044] like Figure 2 As shown, the pin insertion device also includes a cover plate 4. A fixing groove is provided on the side of the fixing platform 2, which is arranged vertically. The cable 200 is placed in the fixing groove. The cover plate 4 can cover the fixing platform 2 and cover the fixing groove. The fixing groove is used to accommodate the cable 200, and the cover plate 4 can work with the fixing groove to fix the cable 200, thereby ensuring the stability of the conductor 202 at the end of the cable 200.

[0045] Specifically, the pin insertion device also includes a locking buckle 5, which is rotatably mounted on the fixed platform 2. One end of the cover plate 4 is rotatably connected to the fixed platform 2. When the cover plate 4 rotates to the fixed platform 2 to block the fixing groove, the locking buckle 5 can engage the other end of the fixed cover plate 4.

[0046] The pin insertion device also includes an elastic element, one end of which abuts against the fixed platform 2 and the other end of which abuts against the locking buckle 5 to drive the locking buckle 5 to rotate toward the cover plate 4, thereby maintaining the lock on the cover plate 4.

[0047] Preferably, the pin device further includes a buffer pad 6, which is fixedly mounted on the cover plate 4. When the cover plate 4 is locked by the locking buckle 5, the buffer pad 6 is located between the cover plate 4 and the cable 200 in the fixing groove and is squeezed by the cover plate 4 and the wire 202. The buffer pad 6 provides cushioning to the cable 200 and the cover plate 4 through compression deformation, so that the clamping force of the cover plate 4 on the cable 200 gradually increases, preventing damage to the cable 200.

[0048] Specifically, such as Figures 3-5As shown, the wiring assembly 1 provided in this embodiment includes a wiring ring 11 and a cover member 12. The wiring ring 11 has a through hole 111 along the axial direction and a plurality of wiring grooves 112 spaced apart along the circumference. Both ends of the plurality of wiring grooves 112 extend to the through hole 111 and the outer periphery of the wiring ring 11. The cover member 12 includes a body 121 and a plurality of pressing parts 122 spaced apart along the circumference of the body 121. The body 121 has a through hole 123. The cover member 12 can cover the wiring ring 11. Each pressing part 122 is inserted into a corresponding wiring groove 112. The pressing part 122 and the corresponding wiring groove 112 form a receiving hole 13.

[0049] After one end of the cable 200 passes through the wire hole 111, the exposed wires 202, after the outer sheath 201 has been removed, can be bent outwards respectively. The bent wires 202 are then placed into their corresponding branch slots 112, and the cover 12 is placed on the branch ring 11, allowing the crimping part 122 to insert into the corresponding branch slot 112. At this point, the operator can align the pin 100 with the position between the multiple wires 202 through the through hole 123 and insert the pin 100 using the crimping head 3. Because the wires 202 of the cable 200 are fixed by the receiving hole 13 formed by the crimping part 122 and the corresponding branch slot 112, the wires 202 are prevented from springing back, ensuring that the bent parts of the wires 202 are all at the same height, thus preventing the wires 202 from being damaged by the crimping head 3.

[0050] In this embodiment, the splitter assembly 1 is described with its flat position as an example, and the cable 200 passes through the cable passage hole 111 from bottom to top. In some embodiments, the splitter assembly 1 can be placed at other angles, as long as the cable 200 passes through the cable passage hole 111 from the direction away from the opening of the splitter groove 112 in the splitter ring 11.

[0051] like Figure 3 As shown, the cable divider 112 includes a first sidewall 113 and a second sidewall 114, and the first sidewall 113 and the second sidewall 114 of the plurality of cable dividers 112 are in the same relative position. That is, whether viewed clockwise or counterclockwise, the first sidewall 113 is located on the same side of the second sidewall 114 of the same cable divider 112. In this embodiment, from top to bottom in a counterclockwise direction, the first sidewall 113 is in front of the second sidewall 114.

[0052] Preferably, the plurality of first sidewalls 113 are inclined outward to form guide surfaces 115, and the plurality of pressing portions 122 are provided with sliding surfaces. The sliding surfaces slide on the guide surfaces 115 to drive the cover member 12 to rotate relative to the wire divider ring 11, so that the pressing portions 122 move closer to or away from the second sidewall 114. When the cover member 12 rotates counterclockwise relative to the wire divider ring 11 and moves closer to the second sidewall 114, the cover member 12 closes onto the wire divider ring 11. When the cover member 12 rotates clockwise relative to the wire divider ring 11, the cover member 12 and the wire divider ring 11 open and separate, and the wire in the wire divider groove 112 can be removed.

[0053] The outward inclination of multiple first sidewalls 113 means that the first sidewalls 113 are inclined away from the second sidewalls 114 along the direction from the dividing ring 11 to the cover member 12. In other words, the closer to the opening of the dividing groove 112, the greater the distance between the first sidewalls 113 and the second sidewalls 114. The inclined first sidewalls 113 form guide surfaces 115, which can guide the wires 202 that have not fully entered the bottom of the dividing groove 112, and also guide the cover member 12 through the sliding surface of the pressing part 122. It is understood that in some embodiments, multiple second sidewalls 114 may also be inclined outward to form guide surfaces 115.

[0054] When the operator bends the conductor 202 of the cable 200 and places it into the corresponding cable tray 112, the conductor 202 will inevitably spring back, causing it to be unstable at the bottom of the cable tray 112. At this time, when the operator uses the pressing part 122 of the cover 12 to press against the conductor 202, the sliding contact surface and the guide surface 115 slide in contact, and the cover 12 rotates counterclockwise as it presses against the cable tray 11. During this process, the conductor 202 is gradually pushed to the bottom of the cable tray 112 by the corresponding pressing part 122 until the pressing part 122 abuts against the second side wall 114, and the relative position of the cover 12 and the cable tray 11 no longer changes, and the conductor 202 is fixed at this time.

[0055] In order to improve the fixing force of the splitter assembly 1 on the wire 202, the diameter of the receiving hole 13 is slightly smaller than the outer diameter of the wire 202. When the splitter ring 11 and the cover 12 are closed together, they can squeeze the wire 202 to ensure the stability of the wire 202.

[0056] like Figure 3 and Figure 5 As shown, the bottom surface of the pressing part 122 has a radially penetrating receiving groove 124. During the process of the cover 12 and the wire divider ring 11 closing, the receiving groove 124 can be used to accommodate and push the wire 202 to prevent the wire 202 from detaching from the pressing part 122.

[0057] like Figure 3As shown, the angle α between the guide surface 115 and the radial surface of the dividing ring 11 gradually increases along the direction of entering the dividing groove 112. The dashed line in the figure is the intersection of the radial surface and the dividing ring 11. That is to say, the inclination angle of the guide surface 115 gradually increases along the direction of entering the dividing groove 112, so that when the pressing part 122 first contacts the guide surface 115, the angle of the guide surface 115 is relatively gentle. At this time, the relative rotation speed between the cover part 12 and the dividing ring 11 is slow, which can smoothly push the wire 202 and prevent the wire 202 from detaching from the pressing part 122. When the wire 202 approaches the bottom of the dividing groove 112, the distance between the pressing part 122 and the second side wall 114 is no longer sufficient for the wire 202 to detach. The increased angle of the guide surface 115 can increase the relative rotation speed between the cover part 12 and the dividing ring 11, and quickly complete the closing action. Furthermore, the portion of the guide surface 115 with a larger tilt angle can also work together with the second side wall 114 to limit the pressing part 122, thereby improving the stability of the relative position between the cover 12 and the dividing ring 11.

[0058] In some embodiments, the splitter assembly 1 further includes a fixing structure, through which the splitter ring 11 and the cover member 12 are fixedly connected. When the cover member 12 covers the splitter ring 11, the fixing structure can fix the cover member 12 and the splitter ring 11, thereby ensuring the stability of the conductor 202.

[0059] Specifically, the fixing structure includes a first adsorption member 141 and a second adsorption member 142. The first adsorption member 141 is disposed on the cover member 12, and the second adsorption member 142 is disposed on the dividing ring 11. The first adsorption member 141 and the second adsorption member 142 face each other and attract each other. Fixing is achieved by the mutual adsorption of the first adsorption member 141 and the second adsorption member 142, resulting in a simple structure and saving space. In this embodiment, both the first adsorption member 141 and the second adsorption member 142 are magnets.

[0060] like Figure 3 and Figure 4 As shown, the first adsorption member 141 is embedded in the pressing part 122, and the second adsorption member 142 is embedded in the second sidewall 114. When the cover member 12 is closed on the dividing ring 11, the pressing part 122 abuts against the second sidewall 114, at which time the first adsorption member 141 and the second adsorption member 142 can adsorb and fix the cover member 12 and the dividing ring 11. In order to improve the stability of the cover member 12 and the dividing ring 11 after they are fixed, each second sidewall 114 is embedded with a second adsorption member 142, and each pressing part 122 is embedded with a first adsorption member 141.

[0061] Preferably, the diameter of the through hole 123 is smaller than the diameter of the wire passage hole 111. That is, the portion of the body 121 of the cover 12 located around the through hole 123 can also press against the wire 202, thereby bringing the controlled range of the wire 202 closer to the bending point of the wire 202, further improving the stability of the wire 202 and preventing it from springing back. Furthermore, the inner walls of the through hole 123 and the wire passage hole 111 form a stepped structure, allowing the operator to easily separate the wire divider ring 11 from the cover 12 when disassembling it, facilitating disassembly.

[0062] like Figure 5 As shown, the body 121 circumferentially abuts against the inner wall of the wire hole 111. The body 121 is at least partially inserted into the wire hole 111, so that the inner wall of the wire hole 111 can position the body 121 radially, thereby ensuring the accuracy of the relative position between the cover 12 and the wire divider ring 11.

[0063] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
