[0029] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with embodiments and drawings. The illustrative embodiments of the present utility model and their descriptions are only used to explain the present utility model and shall not be construed as a limitation to the present utility model.

[0030] Embodiment:

[0031] The interior of the connector includes contact members. After the contact members are connected to the wires, the conduction of electrical signals is achieved. However, the connection part between the contact members and the wires is a weak point in the transmission system and is prone to disconnection between the contact members and the wires due to stress concentration, resulting in the inability to conduct electrical signals and causing faults in the transmission system. Therefore, in the prior art, a tail accessory is added to the tail of the connector. As an extension of the tail of the connector, the tail accessory can protect the connection point between the contact members and the wires inside the metal housing, avoiding the stress on the weak point during the use of the cable assembly.

[0032] The connector and the tail accessory are connected by threads. Inevitably, vibrations or other harsher usage scenarios will occur during actual use. To improve reliability and stability and avoid the loosening of the threads between the connector and the tail accessory during use, anti-loosening measures are added to the connection part between the connector and the tail accessory in the prior art. The commonly used method is to add a pin. It is difficult to disassemble the pin after installation, seriously affecting the separation of the connector and the tail accessory.

[0033] Therefore, a circular tail accessory structure with quick removal and locking is proposed herein. On the basis of ensuring the locking effect, the locking and disassembly can be achieved by reciprocally sliding the locking rod 32. The operation is simpler, and the situation where the pin cannot be removed is effectively avoided. The connection between the connector 1 and the accessory 2 is more flexible, convenient, and has better practicability.

[0034] As Figures 2 - 5 shown, a circular tail accessory structure with quick removal and locking includes a connector 1, an accessory 2, and a locking structure 3;

[0035] The connector 1 is detachably connected to the accessory 2. The locking structure 3 includes a locking groove 31 and a locking rod 32. One of the locking groove 31 and the locking rod 32 is arranged on the connector 1, and the other is arranged on the accessory 2;

[0036] The locking rod 32 can reciprocate, so that the locking rod 32 has a first working position inserted into the locking groove 31 and a second working position disengaged from the locking groove 31;

[0037] When the locking rod 32 is in the first working position, the connector 1 is connected to and fixed to the accessory 2. When the locking rod 32 is in the second working position, the connector 1 and the accessory 2 can rotate relative to each other.

[0038] When the connector 1 is connected to the accessory 2, the ends of the two rotate and are connected. For the locking structure 3, the locking groove 31 and the locking rod 32 also approach each other. When the distance between them is close enough, move the locking rod 32 to the second working position to prevent the locking rod 32 from hindering the connection between the connector 1 and the accessory 2; when the connector 1 and the accessory 2 are connected in place, move the locking rod 32 to the first working position, and the locking rod 32 is also inserted into the locking groove 31, making it difficult for the connector 1 and the accessory 2 to rotate relative to each other, thereby fixing the positions of the connector 1 and the accessory 2; when disassembling the connector 1 and the accessory 2, move the locking rod 32 to the second working position and then rotate the connector 1 and / or the accessory 2.

[0039] Furthermore, during the connection and separation of the connector 1 and the accessory 2, the operations of the staff are to rotate the connector 1 and / or the accessory 2 and move the locking rod 32, and the operations are simple and easy to master.

[0040] Among them, the material of the accessory 2 is the same as that of the connector 1, generally high-strength metal materials such as aluminum alloy, stainless steel, and titanium alloy.

[0041] In a possible implementation, an elastic member 4 is connected to the locking rod 32. An installation groove is provided on the connector 1 or the accessory 2. The locking rod 32 is slidably arranged on the installation groove through the elastic member 4, and the elastic member 4 is arranged in the installation groove.

[0042] Based on the above design, the locking rod 32 can be any suitable shaft rod part. The elastic member 4 provides elastic force for the locking rod 32 to ensure that the locking rod 32 can be in the first working position or the second working position for a long time. Specifically, when the elastic force of the elastic member 4 makes the locking rod 32 in the first working position, the elastic force makes the locking rod 32 extend out of the installation groove, thereby ensuring the locking effect of the connector 1 and the accessory 2, and the electrical signals transmitted by the connector 1 are more reliable and stable. When the elastic force of the elastic member 4 makes the locking rod 32 in the second working position, the elastic force makes the locking rod 32 retract into the installation groove. When the locking rod 32 is inserted into the locking groove 31, the friction between the locking rod 32 and the locking groove 31 is used to ensure that the locking rod 32 is in the first working position.

[0043] Further, when it is necessary to move the locking lever 32 from the first station to the second station, the staff needs to apply a force to achieve the movement of the locking lever 32.

[0044] Preferably, as Figure 3 shown, the locking lever 32 has opposite ends, one end is configured as a locking end adapted to the locking groove 31, and the other end is configured as a connecting end connected to the elastic member 4;

[0045] The locking end has two opposite outer surfaces, one of which is configured as a locking plane 301 and the other is configured as a screwing-in arc surface 302; an additional post extending outward is provided on the connecting end.

[0046] Based on the above design, the locking plane 301 is used to abut against the locking groove 31 to prevent the occurrence of a swirling phenomenon after the connector 1 and the accessory 2 are connected, so as to achieve the effect of anti-retreat locking. The screwing-in arc surface 302 is configured as any suitable curved surface. When the accessory 2 is connected to the connector 1 by rotation, the screwing-in arc surface 302 can make the locking lever 32 move in the direction of the second station under the external pressing action, so that the locking lever 32 can move along the outer circumference of the locking groove 31 and be inserted into the locking groove 31, realizing the rapid embedding of the locking lever 32 into the locking groove 31 and reducing the workload of the staff.

[0047] It is easy to understand that when removing the accessory 2, the staff still needs to manually move the locking lever 32 to the second station to release the connection between the locking plane 301 and the locking groove 31.

[0048] Optionally, anti-slip structures such as anti-slip lines and anti-slip protrusions are provided on the locking plane 301 to increase the friction force and improve the locking effect. It is easy to understand that when the elastic force of the elastic member 4 makes the locking lever 32 in the second station, the anti-slip structure increases the friction force and reduces the probability of the locking lever 32 disengaging from the locking groove 31 under the action of the elastic member 4.

[0049] At the same time, the locking lever 32 uses the additional post to increase the contact area with the elastic member 4, which plays a guiding role in the movement of the locking lever 32 and also plays a role in supporting the elastic member 4 to maintain the shape and tightness of the elastic member 4.

[0050] Optionally, the elastic member 4 is selected from a spiral spring, a spring tube or a rubber spring. Based on the above design, those skilled in the art can also select any other suitable commercially available spring, and the present invention does not make any restrictions on this.

[0051] In a possible implementation manner, the locking groove 31 is configured as an inner groove or a gap between two oppositely arranged lock blocks 5. Based on the above design, as Figure 2As shown, the end of the connector 1 is inserted into the end of the accessory 2 to achieve the connection between the connector 1 and the accessory 2. At this time, for the connection between the connector 1 and the accessory 2, the outer diameter of the connector 1 is smaller than that of the accessory 2. If the locking groove 31 is located on the connector 1, the locking groove 31 is configured as the gap between two relatively arranged locking blocks 5. If the locking groove 31 is located on the accessory 2, the locking groove 31 is configured as an inner groove.

[0052] Similarly, if the end of the accessory 2 is inserted into the end of the connector 1, for the connection between the connector 1 and the accessory 2, the outer diameter of the connector 1 is larger than that of the accessory 2. If the locking groove 31 is located on the connector 1, the locking groove 31 is configured as an inner groove. If the locking groove 31 is located on the accessory 2, the locking groove 31 is configured as the gap between two relatively arranged locking blocks 5.

[0053] In a possible implementation, there is at least one locking structure 3, and when there are multiple locking structures 3, the multiple locking structures 3 are evenly distributed in the circumferential direction of the connector 1. Based on the above design solution, in necessary cases, those skilled in the art can appropriately increase the number of the locking structures 3 as needed to ensure the fastening effect. At the same time, for the multiple locking structures 3, it is preferably evenly distributed in the circumferential direction of the connector 1 so that the locking force acts evenly and unnecessary deformation is avoided.

[0054] In a possible implementation, the connector 1 is provided with an external thread, and the accessory 2 is provided with an inwardly concave connection groove and an internal thread on the inner wall of the connection groove. Based on the above design solution, that is, the connector 1 is threadedly connected to the accessory 2 to achieve the detachable connection between the two, so as to facilitate disassembly and assembly as needed and make the use more flexible and convenient.

[0055] In a possible implementation, the accessory 2 is configured as a hollow structure, and one end of the hollow structure is communicated with the connection groove. Based on the above design solution, the hollow structure facilitates the wire to pass through, without worrying that the accessory 2 affects the connection between the connector 1 and the wire, and ensures that the electrical signal can be conducted smoothly.

[0056] Based on the above-mentioned quickly detachable and lockable circular tail accessory structure, this embodiment introduces a cable, and the cable includes the above-mentioned quickly detachable and lockable circular tail accessory structure. Based on this, the cable replaces anti-loosening measures such as pins with the locking structure 3. On the basis of ensuring the anti-loosening effect, the operation is simpler, the disassembly and assembly of the connector 1 and the accessory 2 are more flexible and convenient, and the practicability is better.

[0057] This embodiment also introduces a transmission system, and the transmission system includes the above-mentioned cable. Based on this, the cable can be used in any suitable transmission system, with a wide range of uses and good practicability.

[0058] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above description is only for the specific embodiments of the present utility model and is not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
