Description

Technical Field

[0001] This utility model belongs to the technical field of cable connectors, and particularly relates to a shockproof connector for cable connection. Background Technology

[0002] In today's electrical and electronic equipment field, cables are indispensable products. They are electrical devices used to transmit power or signals. They are usually composed of one or more mutually insulated conductive cores placed in a sealed sheath. The outside can be covered with a protective covering layer to resist mechanical stress, chemical corrosion and environmental effects. Cables need to be connected at the point of power failure to form a complete circuit route. Connectors are generally used when connecting cables to deal with the adverse effects of the surrounding environment on the cable connection and to ensure that the equipment can work normally.

[0003] Existing cable connectors typically involve plugging the cable into them. To ensure connection strength, some connectors also include additional fixing components to secure the connection, such as threaded connections or snap-fit ​​connections. This connection method can guarantee the stability of the connection to a certain extent. However, in daily use, cables inevitably experience tensile forces. For example, during equipment movement, cable routing adjustments, or accidental dragging, tensile forces will act on the connection between the cable and the connector. Since existing connectors lack a buffering mechanism for tensile forces, all the tensile forces will be concentrated directly at the connection point. This can easily cause wear and tear on the cable sheath, leading to the exposure of the internal wires and posing a risk. In view of this, we propose a shockproof connector for cable connections. Utility Model Content

[0004] The purpose of this invention is to provide a shockproof connector for cable connection to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a shockproof connector for cable connection, including a mounting plate, a connecting mechanism provided in the middle of the mounting plate, the connecting mechanism being used to clamp and fix an external cable, and a connecting block provided at one end of the connecting mechanism; there are two mounting plates, two connecting mechanisms, and two connecting blocks, a stretchable connecting wire is fixedly connected between the two connecting blocks, a tension spring is fixedly connected to one side of the two mounting plates that are close to each other, and a protective mechanism is also provided between the two mounting plates to protect the connecting wire and the tension spring inside.

[0006] In this technical solution, two connecting mechanisms are used to fix the two ends of the cable that need to be connected. The connecting blocks have round holes inside. After the cable end is stripped, the battery core is inserted into the connecting block, while the part with the cable sheath is squeezed and fixed by the connecting mechanism. The two connecting blocks are then connected by a connecting wire to facilitate current transmission. Compared with the existing methods, its feature is that the distance between the two mounting plates can be extended. When the cable is subjected to tensile force, its stress is no longer concentrated at the connection point with the connecting mechanism. The increased distance between the two mounting plates, coupled with the buffering effect of a tension spring, buffers the tensile force and prevents the cable from being damaged at the location of the connecting mechanism.

[0007] In the above technical solution, the connecting mechanism further includes a fixing ring, the outer surface of which is fixedly connected to the mounting plate, and the end of which is fixedly connected to the connecting block. In this technical solution, the fixing ring is used to enclose the cable inside. It is made of insulating material and can separate the connecting block from the outside. The connecting block is made of conductive material and has an insulating layer on its outer surface. The connecting block connects the cable and the connecting wire so that current can flow. The fixing ring is made of phenolic plastic, which has good insulation performance, heat resistance and mechanical strength.

[0008] In the above technical solution, furthermore, a plurality of compression rods are fixedly connected to the end of the fixing ring away from the connecting block, and a fixing knob is threadedly connected to the outer surface of the fixing ring on the outer side of the mounting plate. In this technical solution, during use, the fixing knob is rotated to remove it. First, the fixing knob is placed on the cable, then the cable is passed through the compression rod and the fixing ring. After that, the fixing knob is rotated to fix the fixing knob and the fixing ring. The position where the fixing knob is released from the compression rod has a certain angle, which can compress the compression rod and cause it to deform, thereby pressing the compression rod against the outer surface of the cable to fix the cable. The compression rod is made of rubber. The elasticity of rubber not only helps to fix the cable, but also plays a buffering role when the cable is subjected to external vibration or impact, reducing the impact on the internal structure of the cable and improving the shock resistance of the entire connector.

[0009] In the above technical solution, the protective mechanism further includes an outer ring, an inner ring slidably connected to the inner wall of the outer ring, an end of the outer ring being fixedly connected to one of the mounting plates, and an end of the inner ring being fixedly connected to the other mounting plate. In this technical solution, the outer ring and the inner ring form an inner and outer sleeve structure, and the inner ring and the outer ring can slide, so that the distance between the two mounting plates can be changed.

[0010] In the above technical solution, the inner wall of the outer ring is provided with a sliding groove, and a locking block is slidably connected inside the sliding groove. The outer surface of the locking block is fixedly connected to the inner ring.

[0011] In this technical solution, when the outer ring and the inner ring slide, the sliding groove limits the locking block to prevent excessive sliding and separation.

[0012] In the above technical solution, the middle part of the connecting line is spiral-shaped, and the number of tension springs is three.

[0013] In this technical solution, when the two mounting plates are far apart, the middle part of the connecting wire can be stretched, and its length fully meets the maximum distance between the two mounting plates after they are far apart, forming a telescopic compensation effect. At the same time, the tension spring will be stretched to buffer the external tension. When the external tension disappears, the tension spring will pull the two mounting plates back together to reset. The conductor part of the connecting wire is made of multiple strands of fine copper wire to increase flexibility and conductivity. The outer insulation layer is made of polyvinyl chloride, which can effectively protect the internal conductor.

[0014] The beneficial effects of this utility model are: 1. This cable connector uses a shockproof plug. By incorporating components such as tension springs, when the cable is subjected to tensile force during use, this force is transmitted to the connected mounting plate, increasing the distance between the two mounting plates. As the mounting plates move further apart, the cable is stretched. The tension spring converts the tensile force into its own elastic potential energy, thus buffering the tensile force and preventing stress concentration at the connection point between the cable and the connecting mechanism. This effectively prevents the cable from being damaged due to excessive force at the connection point. This solves the problem of existing plugs lacking a tensile force buffering mechanism, where all tensile force is directly concentrated at the connection point, which can easily cause wear and tear on the cable sheath, leading to exposure of the internal conductors and posing a risk.

[0015] 2. The cable connection uses a shockproof connector. By setting up components such as the connecting wire, the middle of the connecting wire is designed as a spiral. When the two mounting plates move away from each other, the spiral part can be stretched to provide additional expansion and contraction compensation, fully meeting the maximum distance requirement after the two mounting plates move away from each other. When the external pulling force disappears, the tension spring, with its own elastic restoring force, pulls the two mounting plates together to reset, so that the connector returns to its initial state, preparing for the next possible pulling force impact, and ensuring that the cable connection always remains stable and reliable.

[0018] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0019] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0020] Example 1: This example provides a shockproof connector for cable connection, including a mounting plate 1. A connecting mechanism 2 is provided in the middle of the mounting plate 1. The connecting mechanism 2 is used to clamp and fix an external cable 4. A connecting block 3 is provided at one end of the connecting mechanism 2. There are two mounting plates 1, two connecting mechanisms 2 and two connecting blocks 3. A stretchable connecting line 5 is fixedly connected between the two connecting blocks 3. A tension spring 6 is fixedly connected to one side of the two mounting plates 1 that is close to each other. A protective mechanism 7 is also provided between the two mounting plates 1 to protect the connecting line 5 and the tension spring 6 inside.

[0021] In this design, when the cable 4 is connected, the two ends of the cable 4 that need to be connected are fixed by two connecting mechanisms 2. The connecting block 3 has a round hole inside. After the cable 4 is stripped, the battery core is inserted into the connecting block 3, while the part with the cable sheath is squeezed and fixed by the connecting mechanism 2. The two connecting blocks 3 are then connected by a connecting line 5 to facilitate the transmission of current. Compared with the existing design, its feature is that the distance between the two mounting plates 1 can be extended. When the cable 4 is subjected to tensile force, its stress is no longer concentrated at the connection point with the connecting mechanism 2. The distance between the two mounting plates 1 can be increased, and the tension spring 6 is used for buffering, thereby buffering the tensile force and preventing the cable 4 from being damaged at the location of the connecting mechanism 2.

[0022] Example 2: This example provides a shockproof connector for cable connection. In addition to the technical solution of the above example, it also has the following technical features: the connection mechanism 2 includes a fixing ring 201, the outer surface of the fixing ring 201 is fixedly connected to the mounting plate 1, and the end of the fixing ring 201 is fixedly connected to the connecting block 3.

[0023] The fixing ring 201 is used to encase the cable 4 inside. It is made of insulating material and can separate the connecting block 3 from the outside. The connecting block 3 is made of conductive material and has an insulating layer on its outer surface. The connecting block 3 connects the cable 4 and the connecting wire 5 so that current can flow. The fixing ring 201 is made of phenolic plastic, which has good insulation performance, heat resistance and mechanical strength.

[0024] Example 3: This example provides a shockproof connector for cable connection. In addition to the technical solutions of the above examples, it also has the following technical features: a plurality of compression rods 202 are fixedly connected to the end of the fixing ring 201 away from the connecting block 3, and a fixing knob 203 is threadedly connected to the outer surface of the fixing ring 201 on the outer side of the mounting plate 1.

[0025] In use, the fixing knob 203 is rotated to remove it. First, the fixing knob 203 is put onto the cable 4, and then the cable 4 is passed through the compression rod 202 and the fixing ring 201. Then, the fixing knob 203 is rotated to fix the fixing knob 203 to the fixing ring 201. The fixing knob 203 is at a certain angle when it is released from the compression rod 202, which can compress the compression rod 202 and deform it. This allows the compression rod 202 to compress the outer surface of the cable 4, so as to fix the cable 4. The material of the compression rod 202 is rubber. The elasticity of the rubber not only helps to fix the cable 4, but also plays a buffering role when the cable 4 is subjected to external vibration or impact, reducing the impact on the internal structure of the cable 4 and improving the shock resistance of the entire connector.

[0026] Example 4: This example provides a shockproof connector for cable connection. In addition to the technical solutions of the above examples, it also has the following technical features: the protective mechanism 7 includes an outer ring 701, an inner ring 702 is slidably connected to the inner wall of the outer ring 701, the end of the outer ring 701 is fixedly connected to one of the mounting plates 1, and the end of the inner ring 702 is fixedly connected to the other mounting plate 1.

[0027] The outer ring 701 and the inner ring 702 form an inner and outer sleeve structure, and the inner ring 702 and the outer ring 701 can slide, so that the distance between the two mounting plates 1 can be changed.

[0028] Example 5: This example provides a shockproof connector for cable connection. In addition to the technical solutions of the above examples, it also has the following technical features: the inner wall of the outer ring 701 is provided with a sliding groove 703, and a locking block 704 is slidably connected inside the sliding groove 703. The outer surface of the locking block 704 is fixedly connected to the inner ring 702.

[0029] When the outer ring 701 and the inner ring 702 slide, the sliding groove 703 limits the locking block 704 to prevent excessive sliding and separation.

[0030] Example 6: This example provides a shockproof connector for cable connection. In addition to the technical solutions of the above examples, it also has the following technical features: the middle part of the connecting wire 5 is spiral-shaped, and there are three tension springs 6.

[0031] When the two mounting plates 1 are far apart, the middle part of the connecting wire 5 can be stretched, and its length fully meets the maximum distance between the two mounting plates 1 after they are far apart, forming a telescopic compensation effect. At the same time, the tension spring 6 will be stretched to buffer the external tension. When the external tension disappears, the tension spring 6 will pull the two mounting plates 1 back together to reset. The conductor part of the connecting wire 5 is made of multiple strands of fine copper wire to increase flexibility and conductivity. The outer insulation layer is made of polyvinyl chloride, which can effectively protect the internal conductor.

[0032] Working principle: When connecting cable 4, first, put the fixing knob 203 on cable 4, then pass cable 4 through the compression rod 202 and the fixing ring 201 in sequence, and rotate the fixing knob 203. Since the contact position between the fixing knob 203 and the compression rod 202 has a certain angle, as the knob rotates, the fixing knob 203 compresses the compression rod 202. The good elasticity of the rubber compression rod 202 causes it to deform, thereby tightly compressing the outer surface of cable 4 and achieving a firm fixation of cable 4.

[0033] When the cable 4 is subjected to tensile force during use, this tensile force is transmitted to the mounting plate 1 connected to it. Since the two mounting plates 1 are connected by a tension spring 6, and the outer ring 701 and inner ring 702 of the protective mechanism 7 can slide relative to each other, the distance between the two mounting plates 1 is allowed to increase. At this time, as the mounting plates 1 move away from each other, they are stretched, converting the tensile force into their own elastic potential energy, thereby buffering the tensile force and avoiding stress concentration at the connection between the cable 4 and the connecting mechanism 2, effectively preventing the cable 4 from being damaged due to excessive force at the connection mechanism 2.

[0034] The sliding groove 703 on the inner wall of the outer ring 701 of the protective mechanism 7 cooperates with the locking block 704 fixedly connected to the inner ring 702. When the two mounting plates 1 slide relative to each other due to the pulling force, the locking block 704 slides in the sliding groove 703. The sliding groove 703 limits the locking block 704, preventing the outer ring 701 and the inner ring 702 from sliding too much and separating, ensuring that the entire protective mechanism 7 can work continuously and stably, and ensuring the normal operation of the tension spring 6 and the connecting line 5.

[0035] The middle part of the connecting line 5 is designed as a spiral. When the two mounting plates 1 move away from each other, the spiral part can be stretched to provide additional expansion and contraction compensation, which fully meets the maximum distance requirement after the two mounting plates 1 move away from each other. When the external pulling force disappears, the tension spring 6 pulls the two mounting plates 1 together to reset by its own elastic restoring force, so that the connector returns to the initial state, which prepares for the next possible pulling force impact and ensures that the cable connection always remains stable and reliable.
