Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, specifically to an external cable protection device for circuit testing. Background Technology

[0002] In circuit testing, external cables refer to the cables used to connect the test equipment to the circuit or module under test during the circuit testing process. These external cables are typically used to transmit test signals, power, and possible control signals to ensure that test signals can be applied to the circuit under test accurately and reliably, and to receive and transmit the output response of the circuit under test.

[0003] Currently, cable connectors are mainly used to connect external cables to the circuit or module under test. However, after the external cables are connected using connectors, a large portion of the external cables are exposed on the outside, which can easily cause the cables to break. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an external cable protection device for circuit testing, the specific technical solution of which is as follows:

[0005] An external cable protection device for circuit testing includes a support plate and a support assembly, wherein:

[0006] The support assembly is mounted on the pad and includes support ribs, positioning cylinders and combing cylinders. There are multiple support ribs, which are mounted on the pad and distributed circumferentially along the center point of the pad.

[0007] The positioning cylinder is located at the top of the support rib and is used to limit the cable.

[0008] Multiple combing cylinders are arranged on the outside of the positioning cylinder and distributed circumferentially along the axis of the positioning cylinder for combing the cables.

[0009] The pad is provided with multiple staggered holes, which are distributed around the circumference of the axis of the support rib, so that each cable can pass through the pad.

[0010] Preferably, the combing cylinder is provided with a flow guide hole, and the inner wall of each flow guide hole is provided with an electroplated sleeve;

[0011] Preferably, an adjustable constraint ring is sleeved on the outer side of the support rib. The cable passes through the constraint ring and is combed through each guide hole, which can effectively prevent the cables from crossing together. At the same time, by adjusting the position of the constraint ring, the constraint ring moves on the support rib to achieve the function of constraining the cable at different positions.

[0012] Preferably, the upper surface of the pad is provided with an abutment ring, and the abutment ring is located at the bottom end of the support rib. The abutment ring is used to first constrain the connection between the cable and the pad to prevent the cable from shaking and causing wear.

[0013] Furthermore, the abutment ring and the pad are detachably connected;

[0014] Preferably, the pad is provided with a support spring, and the support spring is located on the outside of all the support ribs, so as to gather the support ribs together and prevent the support ribs from tilting when supporting the cable;

[0015] Furthermore, the support spring is detachably connected to the pad.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] (1) By setting up support components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of each structure, the problem of cable breakage caused by the large number of exposed parts on the outside after connection is solved.

[0018] (2) This utility model can effectively prevent cable swaying and wear by first constraining the connection between the cable and the pad by the contact ring.

[0019] (3) This utility model separates the cables by passing them through the constraint ring and through each guide hole, which can effectively prevent the cables from intertwining.

[0020] (4) This utility model achieves the function of constraining the cable at different positions by adjusting the position of the constraint ring and moving the constraint ring on the support rib.

[0021] (5) With the setting of the support spring, the present invention can gather the various support ribs together and prevent the support ribs from tilting when supporting the cable. Attached Figure Description

[0030] like Figure 1 and Figure 2 An external cable protection device for circuit testing is shown, including a support plate 1, on which a support assembly is provided. The support assembly includes a support rib 2, a positioning cylinder 4, and a combing cylinder 5.

[0034] When using the above structure, the staff will install the device in the designated location. When wiring, each cable will pass through the corresponding misalignment hole 8 and through the pad 1. The contact ring 7 will first constrain the connection between the cable and the pad 1 to prevent the cable from shaking and causing wear.

[0035] At the same time, the cables are combed through the constraint ring 3 and through each guide hole 6 to effectively prevent the cables from getting tangled together.
