Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector protection technology, specifically a connector with protection. Background Technology
[0002] In many applications, connecting cables are frequently subjected to external forces such as tension and bending, especially in environments with significant equipment movement or vibration. Traditional connecting cable connectors lack effective cushioning protection, easily leading to wire breakage and poor contact at the connector, affecting the normal operation of the equipment. For example, in industrial automation equipment, connecting cables are frequently subjected to mechanical tension, making connector damage a common occurrence. Furthermore, harsh environments such as humidity and corrosive gases can also damage connectors, reducing the reliability and lifespan of the connecting cable. To address the issues of tensile strength and connector sealing in connecting cables, we propose a connecting cable with a protective connector. Utility Model Content The purpose of this utility model is to provide a connector with a protective joint to solve the problems of tensile strength and joint sealing in existing connectors mentioned in the background art.
[0003] To achieve the above objectives, this utility model provides the following technical solution: a connector with a protected connecting wire, including a first connector, a second connector, and an adjusting sleeve. The opposite ends of the first connector and the second connector are respectively provided with a cable core first and a cable core second. The opposite ends of the first connector and the second connector are respectively provided with a connecting end first and a connecting end second. The opposite surfaces of the connecting end first and the connecting end second are each annularly distributed with insertion holes. A connector is movably inserted into each insertion hole, and a rubber sleeve is fitted onto the connector. The adjusting sleeve corresponds to the first connector and the second connector. One side of the second component is threadedly connected to limit end one and limit end two respectively. The plug-in component is fixedly installed on limit end one and limit end two on the corresponding side. Sloping surfaces are provided at corresponding positions on limit end one and limit end two. Sealing ring one is provided on both sides of the adjusting sleeve. Sealing ring one is in rolling contact with the sloping surface. Sealing ring two is provided at the opposite ends of limit end one and limit end two. Sealing ring one and sealing ring two are both located outside of connection one and connection two, and the inner diameter of sealing ring one is larger than the outer diameter of sealing ring two.
[0004] Preferably, the first sealing ring is disposed between adjacent second sealing rings, and the centers of the first sealing ring and the second sealing ring are collinear.
[0005] Preferably, the adjusting sleeve and the first and second limiting ends are all collinear, and the outer diameter of the adjusting sleeve is larger than the outer diameter of the first and second limiting ends.
[0006] Preferably, both the first connecting end and the second connecting end are located between adjacent first and second limiting ends, and the outer diameters of the first connecting end and the second connecting end are equal to the inner diameters of the first limiting end and the second limiting end, respectively.
[0007] Preferably, the first cable core and the second cable core are in electrical contact, and both the first cable core and the second cable core are located inside the adjusting sleeve.
[0008] Preferably, the threads at both ends of the adjusting sleeve rotate in opposite directions.
[0009] Preferably, the connector is arranged in a ring outside of wire one and wire two, and the center lines of the connector and wire one and wire two are parallel to each other.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of connector has a protected connecting wire. By setting an adjusting sleeve between wire one and wire two, after rotating the adjusting sleeve, the limiting end one and the limiting end two move from the outside to the inside at the same time. When the limiting end one and the limiting end two move from the outside to the inside at the same time, the cable core one and the cable core two at the corresponding ends of wire one and wire two can be driven to move from the outside to the inside at the same time, so that the cable core one and the cable core two are electrically connected. During this process, the elastic reset effect of the sealing ring one can further improve the contact sealing between the limiting end and the adjusting sleeve, while the setting of the sealing ring two can improve the contact sealing between the limiting end and the wire. In summary, the technical solution of this application can improve the compressive strength of the wiring end, prevent pulling, and separate wiring one and wiring two, thereby preventing loosening at the connection joint and further ensuring the contact stability of the wiring; and the sealing ring one and sealing ring two can increase the sealing of the connection joint and play a role in protecting the joint.
[0011] 2. This type of connector has a protected connecting wire. By rotating the adjusting sleeve, the circuit can be connected. At the same time, by continuing to rotate the adjusting sleeve, the processing and installation errors of the wiring during production and installation can be compensated, further ensuring the stable and safe use of the connecting wire.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a connector with a protected connecting wire, including a first connector 1, a second connector 2, and an adjusting sleeve 5. The opposite ends of the first connector 1 and the second connector 2 are respectively provided with a first cable core 3 and a second cable core 4. Both the first cable core 3 and the second cable core 4 are conductors inside the first connector 1 and the second connector 2, respectively, and are electrically in contact. Both the first cable core 3 and the second cable core 4 are located inside the adjusting sleeve 5. After the first cable core 3 and the second cable core 4 make electrical contact, the first connector 1 and the second connector 2 can be electrically connected.
[0016] Please see Figure 1 The opposite ends of wire 1 and wire 2 are respectively provided with connection terminal 6 and connection terminal 7, and connection terminal 6 and connection terminal 7 are fixedly installed with the corresponding wire 1 and wire 2. Insertion holes 14 are arranged in a ring on the opposite surfaces of connection terminal 6 and connection terminal 7, wherein the insertion holes 14 facilitate the alignment and connection of other components with connection terminal 6 and connection terminal 7.
[0017] Furthermore, a connector 15 is movably inserted into the socket 14. The connector 15 is arranged in a ring outside the first wire 1 and the second wire 2, and the center lines of the connector 15 and the first wire 1 and the second wire 2 are parallel to each other.
[0018] In this example, a rubber sleeve 12 is fitted onto the connector 15. The rubber sleeve 12 is made of flexible rubber. When wire 1 and wire 2 are pulled to both sides, the elasticity of the rubber sleeve 12 can provide a certain tensile strength, thereby preventing the wire 1 and wire 2 from separating and causing the connector to loosen. This further ensures the contact stability of the wiring.
[0019] Please see Figure 1 and Figure 3Limiting ends 8 and 9 are threadedly connected to one side of the adjusting sleeve 5 corresponding to wiring 1 and wiring 2, respectively, with the threads at both ends of the adjusting sleeve 5 rotating in opposite directions. Connector 15 is fixedly installed on the corresponding limiting ends 8 and 9. The adjusting sleeve 5, limiting ends 8 and 9 are all collinear, and the outer diameter of the adjusting sleeve 5 is larger than the outer diameters of the limiting ends 8 and 9. Connecting ends 6 and 7 are both located between adjacent limiting ends 8 and 9, and the outer diameters of connecting ends 6 and 7 are equal to the inner diameters of the limiting ends 8 and 9, respectively. By inserting the connector 15 into the connector hole 14, after the adjusting sleeve 5 rotates, the first limiting end 8 and the second limiting end 9 can move simultaneously from the inside out or from the outside in. When the first limiting end 8 and the second limiting end 9 move outwards simultaneously, it facilitates the separation of the first wiring 1 and the second wiring 2. When the first limiting end 8 and the second limiting end 9 move inwards simultaneously, the first connecting end 6 and the second connecting end 7 move inwards simultaneously, thereby driving the corresponding ends of the first wiring 1 and the second wiring 2, the cable core 3 and the cable core 4, to move inwards simultaneously, so that the cable core 3 and the cable core 4 are electrically connected, thereby realizing the connection of the line. Furthermore, by continuing to rotate the adjusting sleeve 5, the processing and installation errors of the wiring during production and installation can be compensated, further ensuring the stable and safe use of the connecting line.
[0020] Furthermore, ramps 13 are provided at corresponding positions on both the first limiting end 8 and the second limiting end 9. The ramps 13 are provided as follows: Figure 3 As shown, sealing rings 10 are provided on both sides of the adjusting sleeve 5, and sealing rings 10 roll in contact with the inclined surface 13. Sealing rings 11 are provided at the opposite ends of limiting end 8 and limiting end 9. Sealing rings 10 and 11 are both located outside of terminals 1 and 2, and the inner diameter of sealing ring 10 is larger than the outer diameter of sealing ring 11. Sealing ring 10 is located between adjacent sealing rings 11, and their centers are collinear. Both sealing rings 10 and 11 are hollow and made of flexible rubber. The use of sealing rings 10 and 11 further improves the sealing performance at the joint, thus protecting the joint between terminals 1 and 2. Specifically, by using the sealing ring 10, when the adjusting sleeve 5 is rotated, causing the limiting end 8 and the second limiting end 9 to move simultaneously from the outside in, the slope surface 13 allows the sealing ring 10 to undergo a certain degree of compression deformation. The elastic reset effect of the sealing ring 10 further improves the contact sealing between the limiting end and the adjusting sleeve 5. The sealing ring 11 further improves the contact sealing between the limiting end and the wiring.
[0021] Working principle: This type of connector has a protected connecting wire. When wire 1 and wire 2 are connected, by rotating the adjusting sleeve 5, the limiting end 8 and the limiting end 9 can move simultaneously from the inside to the outside or from the outside to the inside. When the limiting end 8 and the limiting end 9 move simultaneously outward, it facilitates the separation of wire 1 and wire 2. When the limiting end 8 and the limiting end 9 move simultaneously from the outside to the inside, it enables the connecting end 6 and the connecting end 7 to move simultaneously from the outside to the inside, thereby driving the cable core 3 and the cable core 4 at the corresponding ends of wire 1 and wire 2 to move simultaneously from the outside to the inside, so that the cable core 3 and the cable core 4 are electrically connected.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
