Description

Technical Field

[0001] The utility model relates to the technical field of adapters for testing cables, in particular to an adapter for testing cables. Background Art

[0002] The test cable uses adapters to make the cable a continuous line. Each section of the cable must be connected as a whole. These connection points are called cable adapters.

[0003] For example, an adapter for a test cable with the authorization announcement number "CN220190070U" has an L-shaped device shell for fixing the internal parts of the device, an insulating material, and is injection molded in one piece. The pressure rod is used to compress the wire under the action of a coil spring, and the stroke is limited by the inner cavity in the L-shaped device shell, retaining one degree of freedom for sliding. The conductive plate is made of copper, and the clamping bolt clamps the wire at one end of the adapter cable to fix it, achieving good conductive performance, stable contact and anti-interference after wiring, and convenient operation. However, when using the adapter for the test cable, the connector uses an elastic component to compress the cable, and the elastic pressure force points are uneven. In order to ensure the stability of the cable connection, the elastic force will be larger. In this way, one point of the cable will be continuously compressed, which may easily cause the cable to deform and affect the internal wire core, affecting the normal transmission of the adapter for the test cable, and thus limiting the use of the adapter for the test cable. Utility Model Content

[0004] The utility model aims to solve the problem that the normal transmission of the test cable adapter is affected and the test cable adapter has usage limitations, and proposes a test cable adapter.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A test cable adapter is designed, comprising a round sleeve, the rear end face of the round sleeve is fixedly connected to the adapter, the front of the left and right sides of the adapter are connected to control structures, the top of the control structure is connected to a fixed structure, the inner wall of the fixed structure is plugged with a straight plate, the bottom front end of the straight plate is fixedly connected to a bracket, the top rear of the straight plate is processed with a round opening, and the inner side of the control structure is fitted with the outer wall of the adapter.

[0007] Preferably, the control structure includes a bent rod and a circular ring, the inner sides of the two bent rods are respectively fixedly connected to the left and right front sides of the adapter, the outer wall of the bent rod is plugged into the circular opening of the outer wall of the circular ring, and the inner wall of the circular ring is fixedly connected with multiple curved blocks.

[0008] Preferably, the inner sides of the plurality of curved blocks are in contact with the outer wall of the adapter.

[0009] Preferably, the fixing structure comprises a square frame and a screw rod, the bottom of the square frame is fixedly connected to the top of the circular ring, the top of the square frame is threadedly connected to the outer wall of the screw rod, and the top of the screw rod is fixedly connected with a handle.

[0010] Preferably, the inner wall of the square frame is plugged into the rear of the outer wall of the straight board.

[0011] Preferably, the bottom diameter of the screw rod matches the inner diameter of the top circular opening of the straight plate.

[0012] The utility model provides an adapter for a test cable, which has the following beneficial effects: by pushing the circular ring forward in the control structure, the circular ring moves forward with the curved block to fit the surface of the circular sleeve; since the circular sleeve gradually tilts from back to front, when the curved block moves forward, the circular sleeve will deform inward to press the test cable tightly, thereby improving the connection stability between the test cable and the adapter, changing the original single-point elastic pressing form, avoiding damage to the test cable, ensuring normal transmission of the adapter for the test cable, and eliminating limitations on use.

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5In the present embodiment, an adapter for a test cable includes a round sleeve 1, the round sleeve 1 is made of rubber, the rear end face of the round sleeve 1 is fixedly connected to an adapter 4, the model of the adapter 4 is selected according to usage requirements, the left and right front sides of the adapter 4 are connected to a control structure 2, the top of the control structure 2 is connected to a fixed structure 3, the inner wall of the fixed structure 3 is plugged with a straight plate 5, the bottom front end of the straight plate 5 is fixedly connected to a bracket 6, the top rear of the straight plate 5 is processed with a circular opening, and the inner side of the control structure 2 fits with the outer wall of the adapter 4.

[0022] The control structure 2 includes a curved rod 201 and a circular ring 202. The inner sides of the two curved rods 201 are respectively fixed to the front of the left and right sides of the adapter 4. The outer wall of the curved rod 201 is plugged into the outer wall of the circular ring 202. The circular ring 202 is forced to move forward and backward on the outer wall of the curved rod 201. The inner wall of the circular ring 202 is fixed with a plurality of curved blocks 203. The inner sides of the plurality of curved blocks 203 are all in contact with the outer wall of the adapter 4.

[0023] By pushing the circular ring 202 forward in the control structure 2, the circular ring 202 moves forward with the curved block 203 to fit the surface of the circular sleeve 1. Since the circular sleeve 1 gradually tilts from the back to the front, when the curved block 203 moves forward, the circular sleeve 1 will deform inward to press the test cable tightly, thereby improving the connection stability between the test cable and the adapter 4, changing the original single-point elastic pressing form, avoiding damage to the test cable, ensuring the normal transmission of the test cable using the adapter, and eliminating usage limitations.

[0024] The fixed structure 3 includes a square frame 301 and a screw 302. The bottom of the square frame 301 is fixedly connected to the top of the ring 202. The top of the square frame 301 is threadedly connected to the outer wall of the screw 302. The screw 302 is subjected to force to rotate up and down through the top of the square frame 301. A handle 303 is fixedly connected to the top of the screw 302. The handle 303 is convenient for driving the screw 302 to rotate. The inner wall of the square frame 301 is plugged into the rear of the outer wall of the straight plate 5. The bottom diameter of the screw 302 matches the inner diameter of the top circular opening of the straight plate 5.

[0025] Working principle:

[0026] Adapter and test cable installation:

[0027] Insert the connecting end of the test cable into the circular sleeve 1, and then push the test cable forward to make it plug into the connection of the adapter 4, and then push the circular ring 202 forward on the outer wall of the adapter 4, and the circular ring 202 moves forward with the curved block 203 to fit the surface of the circular sleeve 1. Since the circular sleeve 1 gradually tilts from back to front, when the curved block 203 moves forward, the circular sleeve 1 will deform inward to press the test cable tightly, thereby improving the connection stability of the test cable and the adapter 4. At this time, the position of the square frame 301 is located at the bottom, and then the rear of the adapter 4 is plugged into the interface of the detection equipment.

[0028] Adapter connection test cable support:

[0029] Since the square frame 301 is at the bottom at this time, hold the handle 303 and rotate the screw 302 downward through the square frame 301, then insert the rear of the outer wall of the straight plate 5 into the square frame 301, and then rotate the handle 303 and the screw 302 upward through the square frame 301, so that the upper part of the outer wall of the screw 302 is plugged into the circular opening of the outer wall of the straight plate 5, and the inner wall of the bracket 6 at the end of the straight plate 5 fits with the outer wall of the test cable to support the test cable.
