Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a detachable cable connector structure. Background Technology

[0002] A cable connector is a device used for electrical or signal transmission to reliably connect two or more cables, or to connect cables to equipment (such as circuit boards, sockets, terminal equipment, etc.). Its core function is to ensure the stable transmission of current, data, or signals, while guaranteeing the reliability, stability, and security of the connection. It is widely used in many fields such as power systems, communication networks, industrial control, automotive electronics, and aerospace.

[0003] Existing cable connectors are used by disassembling the connector body, inserting the cable into the connector body, connecting the cable cores to the terminals inside the connector body, then closing the connector body to compress and secure the cable, and finally inserting the connector body into the device's socket to achieve the connection between the cable and the device.

[0004] However, when the cable connector body or cable needs maintenance or replacement, the cable connector body must be disassembled before subsequent operations can be performed. This may result in uneven force or angle deviation when disassembling the cable connector body, causing the pins inside the cable connector body to bend or the shell to crack, thus rendering the entire connector body unusable and increasing maintenance costs. Utility Model Content

[0005] The technical problem this utility model aims to solve is that uneven force or angular deviation during the disassembly of the cable connector body can cause the pins inside the cable connector body to bend or the outer shell to crack, resulting in the scrapping of the entire connector body and increasing maintenance costs.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a detachable cable connector structure, including: a connector body, on one side of which a cable is provided, wherein the connector body is used to realize the electrical connection between the cable and electrical equipment; a connecting device, wherein the connecting device is disposed between the connector body and the cable, wherein the connecting device can separate the cable and the connector body into two independent entities, so that the cable and the connector body can be quickly disassembled and assembled.

[0007] Preferably, the connecting device includes: a rectangular tube fixedly connected to the connector body, wherein a connecting post is fixedly connected to one side of the rectangular tube, and the connecting post is connected to a terminal inside the connector body; a first copper plate fixedly connected inside the rectangular tube, wherein the first copper plate is fixedly connected to the connecting post, and the connecting post is made of copper; a second copper plate slidably mounted on the rectangular tube via a base, wherein a bolt is provided inside the base, and the surface of the bolt is threadedly connected to the inner wall of a hole on the inner side of the rectangular tube, wherein the second copper plate is placed inside the rectangular tube and fits against the surface of the first copper plate; a terminal block fixedly connected to the base, wherein the terminal block is made of copper, and the terminal block is fixedly connected to the second copper plate; a threaded ring fixedly connected to the base, wherein the threaded ring sleeves the terminal block; and a threaded sleeve, wherein a retaining ring is rotatably connected to the inner wall of the threaded sleeve, wherein the retaining ring is fixedly connected to a cable, and the inner wall of the threaded sleeve is threadedly connected to the surface of the threaded ring.

[0008] The aforementioned components achieve the following effect: By setting up a connecting device, the base is first manually moved to move the second copper plate. When the base is fully inserted into the rectangular tube, the surfaces of the second and first copper plates are in contact. At this point, a bolt is screwed into the hole in the rectangular tube through the base thread to fix the base, completing the assembly and fixation of the base and the rectangular tube. Then, the cable core is wound and fixed onto the terminal block. Next, the threaded sleeve is manually rotated, causing it to rotate along the surface of the retaining ring. When the threaded sleeve is fully screwed to the surface of the threaded ring, the threaded ring and threaded sleeve, in conjunction with the retaining ring, fix the cable in position, completing the assembly and fixation between the cable and the base. Simultaneously, the cable core is electrically connected to the connector body through the terminal block, the second copper plate, the first copper plate, and the connecting post. The assembly of the cable and connector body allows for quick separation of the cable from the connector body when it needs replacement due to aging. Similarly, when the connector body is damaged, it can be quickly separated from the cable via the rectangular tube. This allows for individual assembly and disassembly of the cable and connector body using a connecting device, preventing the force generated during disassembly from directly acting on the connector body or cable. This protects the connector body during disassembly and reduces the risk of uneven force or angular deviations during disassembly, which could lead to bent pins or cracked shells, rendering the entire connector unusable and increasing maintenance costs. This improves the convenience of assembling and disassembling the connector body or cable while effectively reducing damage to the connector body during assembly and disassembly.

[0009] Preferably, the surface of the threaded sleeve is fixed with a plurality of anti-slip strips, and the plurality of anti-slip strips are arranged at equal intervals.

[0010] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the surface of the threaded sleeve can be increased, reducing the chance of slipping when manually rotating the threaded sleeve.

[0011] Preferably, a rubber pad is fixed to the side of the threaded ring away from the base.

[0012] The effect achieved by the above components is that by setting rubber pads, the gap between the threaded sleeve and the threaded ring can be filled and sealed, while preventing direct contact between the two, reducing contact wear between them, and improving service life.

[0013] Preferably, the base has a storage groove on the side near the bolt hole, wherein the inner wall of the storage groove is larger than the surface of the bolt nut.

[0014] The effect achieved by the above components is that by setting up a storage groove, the bolt nut can be completely retracted into the storage groove, so that the bolt nut is lower than the base surface, thus preventing the bolt nut from rotating due to collisions or contact with foreign objects, which would affect the fixing effect.

[0015] Preferably, a pull rod is fixed to one side of the base, wherein the inner side of the pull rod is provided with multiple anti-slip protrusions.

[0016] The effect achieved by the above components is that by setting up the pull rod, a force point can be provided for personnel to manually move the base, so that personnel can manually pull the pull rod to move the base out of the rectangular tube, thereby improving the convenience of manually pulling the base.

[0017] Preferably, a locking block is fixed to one side of the second copper plate, and a locking groove is formed on the surface of the first copper plate, wherein the surface of the locking block is slidably connected to the inner wall of the locking groove, and the locking block is made of copper.

[0018] The effect achieved by the above components is as follows: by setting the locking block, the locking block can be moved to a position where it is fully inserted into the slot to assist in limiting the second copper plate, further improving the connection stability between the first copper plate and the second copper plate, while increasing the contact area between the two, making them fit more tightly, and improving the stability of current transmission.

[0019] Preferably, the gap between the base and the rectangular tube is filled with glue, wherein the glue is a polyurethane hot melt adhesive.

[0020] The effect achieved by the above components is that by injecting glue into the gap between the rectangular tube and the base, the glue can seal the gap, increase the sealing between the rectangular tube and the base, and reduce the possibility of water seepage inside the rectangular tube.

[0021] The beneficial effects of this utility model are:

[0022] By setting up a connection device, the disassembly and assembly of the connector body and the cable can be carried out within the range of the connection device. The force generated during the disassembly and assembly process is applied to the connection device, avoiding disassembly damage to the connector body. This reduces the possibility of the internal pins bending or the outer shell cracking due to uneven force or angular deviation during disassembly and assembly, which could lead to the scrapping of the entire connector body and increase maintenance costs. It improves the convenience of disassembling and assembling the connector body or cable, while effectively reducing the damage to the connector body during disassembly and assembly.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-5 The detachable cable connector structure shown includes: a connector body 1, on one side of which a cable 2 is provided, wherein the connector body 1 is used to realize the electrical connection between the cable 2 and the electrical equipment; and a connecting device 3, which is disposed between the connector body 1 and the cable 2, wherein the connecting device 3 can separate the cable 2 and the connector body 1 into two independent entities, so that the cable 2 and the connector body 1 can be quickly disassembled and assembled.

[0033] Figure 2-5The connecting device 3 shown includes: a rectangular tube 31, which is fixedly connected to the connector body 1, wherein a connecting post 32 is fixedly connected to one side of the rectangular tube 31, and the connecting post 32 is connected to a terminal inside the connector body 1; a first copper plate 33, which is fixedly connected inside the rectangular tube 31, and is fixedly connected to the connecting post 32, wherein the connecting post 32 is made of copper; a second copper plate 36, which is slidably mounted on the rectangular tube 31 via a base 35, wherein a bolt 38 is provided inside the base 35, wherein the surface of the bolt 38 is threaded to the inner wall of a hole on the inner side of the rectangular tube 31, wherein the second copper plate 36 is placed inside the rectangular tube 31 and is in contact with the surface of the first copper plate 33; and a terminal 312, which is connected to the base. 35 is fixedly connected, wherein the terminal 312 is made of copper and is fixedly connected to the second copper plate 36; a threaded ring 311 is fixedly connected to the base 35, wherein the threaded ring 311 sleeves the terminal 312; a threaded sleeve 315 has a retaining ring 314 rotatably connected to its inner wall, wherein the retaining ring 314 is fixedly connected to the cable 2, wherein the inner wall of the threaded sleeve 315 is threadedly connected to the surface of the threaded ring 311. By setting the connecting device 3, the base 35 is first manually moved to move the second copper plate 36. When the base 35 moves to the position where it is fully inserted into the rectangular tube 31, the surfaces of the second copper plate 36 and the first copper plate 33 are in contact with each other. At this time, a bolt 38 is screwed into the rectangular tube 31 through the threads of the base 35 using a tool. The base 35 is fixed inside the hole, completing the assembly and fixation of the base 35 and the rectangular tube 31. At this time, the core of the cable 2 is wound and fixed on the terminal block 312. Then, the threaded sleeve 315 is manually rotated, causing the threaded sleeve 315 to rotate along the surface of the retaining ring 314. When the threaded sleeve 315 is fully turned to the position of the threaded ring 311, the threaded ring 311, the threaded sleeve 315, and the retaining ring 314 fix the position of the cable 2, completing the assembly and fixation between the cable 2 and the base 35. At the same time, the core of the cable 2 is electrically connected to the connector body 1 through the terminal block 312, the second copper plate 36, the first copper plate 33, and the connecting post 32, thus completing the assembly of the cable 2 and the connector body 1. When the cable 2 ages and needs to be replaced, it can be directly replaced through the terminal block 312. The wire post 312 quickly separates it from the connector body 1. At the same time, when the connector body 1 is damaged, it can be quickly separated from the cable 2 directly through the rectangular tube 31. This allows the cable 2 and the connector body 1 to be disassembled and assembled separately using the connecting device 3. This avoids the force generated during disassembly from acting directly on the connector body 1 or the cable 2, thus completing the disassembly protection of the connector body 1. It also reduces the possibility of uneven force or angle deviation when disassembling the connector body 1, which could lead to bending of the pins inside the connector body 1 or cracking of the outer shell, causing the entire connector body 1 to be scrapped and increasing maintenance costs. This improves the convenience of disassembling and assembling the connector body 1 or the cable 2, while effectively reducing the damage to the connector body 1 during disassembly and assembly.

[0034] Figure 2-5 The threaded sleeve 315 shown has multiple anti-slip strips 316 fixedly attached to its surface. The multiple anti-slip strips 316 are arranged at equal intervals. By setting the anti-slip strips 316, the friction between the hand and the surface of the threaded sleeve 315 can be increased, reducing the possibility of slippage when manually rotating the threaded sleeve 315. A rubber pad 313 is fixedly attached to the side of the threaded ring 311 away from the base 35. By setting the rubber pad 313, the gap between the threaded sleeve 315 and the threaded ring 311 can be filled and sealed, while preventing direct contact between the two, reducing contact wear between them, and improving service life.

[0035] Figure 2-5 The base 35 shown has a storage groove 39 on the side near the bolt 38 hole. The inner wall of the storage groove 39 is larger than the surface of the bolt 38 nut. By setting the storage groove 39, the bolt 38 nut can be completely retracted into the storage groove 39, so that the bolt 38 nut is lower than the surface of the base 35. This prevents the bolt 38 nut from rotating due to collision or contact with foreign objects, which would affect the fixing effect. A pull rod 310 is fixed to one side of the base 35. The inner side of the pull rod 310 has multiple anti-slip protrusions. The pull rod 310 provides a point of leverage for personnel to manually move the base 35, allowing personnel to manually pull the pull rod 310 to move the base 35 out of the rectangular tube 31, improving the convenience of manually pulling the base 35.

[0036] Figure 2-5 A locking block 37 is fixed to one side of the second copper plate 36. A slot 34 is formed on the surface of the first copper plate 33. The surface of the locking block 37 is slidably connected to the inner wall of the slot 34. The locking block 37 is made of copper. By setting the locking block 37, the locking block 37 can be moved to a position where it is fully inserted into the slot 34 to assist in limiting the second copper plate 36, further improving the connection stability between the first copper plate 33 and the second copper plate 36. At the same time, it increases the contact area between the two, making them fit more tightly and improving the stability of current transmission. Glue is injected into the gap between the base 35 and the rectangular tube 31. The glue is a polyurethane hot melt adhesive. By injecting glue into the gap between the rectangular tube 31 and the base 35, the glue can seal the gap, increase the sealing between the rectangular tube 31 and the base 35, and reduce the possibility of water seepage inside the rectangular tube 31.

[0037] Working principle: First, manually move the base 35 to move the second copper plate 36. When the base 35 is fully inserted into the rectangular tube 31, the surfaces of the second copper plate 36 and the first copper plate 33 are in contact. At this time, use a tool to screw the bolt 38 into the hole of the rectangular tube 31 through the thread of the base 35 to fix the base 35, completing the assembly and fixation of the base 35 and the rectangular tube 31. Then, wrap and fix the core of the cable 2 around the terminal block 312. Next, manually rotate the threaded sleeve 315 so that the threaded sleeve 315 rotates along the surface of the retaining ring 314. When the threaded sleeve 315 is fully rotated to the surface of the threaded ring 311, the threaded ring 311 and the threaded sleeve 315, together with the retaining ring 314, position the cable 2. The cable 2 is fixed in place, and the assembly between the cable 2 and the base 35 is fixed. At the same time, the core of the cable 2 is electrically connected to the connector body 1 through the terminal block 312, the second copper plate 36, the first copper plate 33 and the connecting post 32, thereby completing the assembly of the cable 2 and the connector body 1. When the cable 2 ages and needs to be replaced, it can be quickly separated from the connector body 1 directly through the terminal block 312. At the same time, when the connector body 1 is damaged, it can be quickly separated from the cable 2 directly through the rectangular tube 31. This allows the cable 2 and the connector body 1 to be disassembled and assembled separately using the connecting device 3, avoiding the force generated by the disassembly operation from acting directly on the connector body 1 or the cable 2, thereby completing the disassembly protection of the connector body 1.
