Description

Technical Field

[0001] The present application relates to the technical field of gauges, and more specifically, to an electric contact gauge. Background Art

[0002] Electrical contacts are important components of high-voltage circuit breakers, switch cabinets, disconnectors, and grounding switches. Their performance directly affects the quality and service life of these high-voltage electrical appliances. When they are in contact, the circuit is connected. Their relative movement can open or close the circuit, or they can keep the circuit connected by rotating or sliding. Silver contacts refer to the intersections where electronic appliances separate and contact each other when they are opened and closed. Silver contacts are a type of electrical contacts. During the production process, it is often necessary to use inspection tools to conduct random inspections on silver contacts.

[0003] The document with the prior art publication number CN212585650U provides a detection fixture for detecting the thickness of the silver layer of an electric contact. When the detection fixture is used, the detection block moves backward to the initial position under the action of a pair of guide columns, and the silver layer part of the electric contact is placed in the width corresponding to the size of the detection slot. The width difference between adjacent detection slots is mm. After the silver layer part is firmly installed in the detection slot, force is applied to the detection block to move it toward the front end surface of the through slot. The protruding part of the electric contact and the front end surface of the through slot and the front end surface of the detection block are mutually in conflict. The silver layer is clamped by the first clamping surface and the second clamping surface. Then, it is checked whether the silver layer is firmly installed by swinging left and right. When it is firmly installed, it can be known that the thickness of the silver layer is consistent with the size of the detection slot into which it is inserted, so that the thickness of the silver layer to be detected can be quickly, clearly and accurately known, which can avoid the cumbersome detection process and the low efficiency caused by the low efficiency, and improve the detection accuracy and work efficiency.

[0004] Although the device has many beneficial effects, the following problems still exist: when the staff inspects the raised part of the contact, after clamping the contact, the staff needs to swing it left and right to check whether the silver layer is firmly installed. It is difficult to quickly measure the thickness of the raised part of the contact, which makes it difficult for the staff to quickly determine whether the contact is qualified, which easily reduces the staff's random inspection efficiency. In view of this, we propose an electrical contact inspection fixture. Utility Model Content

[0005] By providing a kind of electric contact detector in the embodiment of the present application, the technical problem in the prior art that when the staff detects the convex part of the contact, after clamping the contact, the staff still needs to swing left and right to check whether the silver layer is firmly installed, it is difficult to quickly measure the thickness of the convex part of the contact, and then it is difficult for the staff to quickly determine whether the contact is qualified, and it is easy to reduce the sampling inspection efficiency of the staff is solved, and the technical effect that when the staff detects the silver contact, the thickness of the convex part of the silver contact can be quickly measured, so as to facilitate the staff to quickly determine whether the thickness of the electric contact is qualified, reduce the operation steps, and then facilitate improving the sampling inspection efficiency of the staff is realized.

Detailed implementation manners

[0028] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0029] Referring to Figure 1 and Figure 2 , an electric contact detector is disclosed in an embodiment of the present application. The electric contact detector includes: a mounting frame 1;

[0030] A groove 6 is formed at the bottom of the inner wall of the mounting frame 1, and a contact body 2 is arranged in the groove 6. The contact body 2 includes a first substrate 21 and a second substrate 22. A detection mechanism 3 is arranged at the top of the mounting frame 1 for detecting whether the thickness of the second substrate 22 is qualified;

[0031] The detection mechanism 3 includes a connecting plate 31. A sliding rod 32 is slidably connected through the top of the mounting frame 1. The top end of the sliding rod 32 is fixedly connected to the bottom of the connecting plate 31, and the bottom end of the sliding rod 32 is fixedly connected to a mounting ring 33. A sliding plate 36 is slidably sleeved on the outer sides of the two sliding rods 32. A scale 39 is arranged on one side of the top of the mounting ring 33, which is convenient for the staff to quickly detect whether the second substrate 22 is qualified.

[0032] Referring to Figure 1 and Figure 3 , a fixing plate 37 is fixedly connected to one side of the sliding plate 36, and a pointer 38 is fixedly connected to one side of the fixing plate 37, which is convenient for the staff to quickly determine the thickness of the second substrate 22.

[0033] Referring to Figure 1 and Figure 3 , the depth of the inner side of the groove 6 is less than the height of the first substrate 21, the size of the inner side of the mounting ring 33 is greater than the size of the second substrate 22, and the size of the inner side of the mounting ring 33 is less than the size of the first substrate 21, so that the mounting ring 33 can be abutted against the top of the first substrate 21.

[0034] Referring to Figure 1 and Figure 3, a through groove is provided on one side of the top of the installation frame 1, which facilitates the unobstructed up and down movement of the scale 39.

[0035] Refer to Figure 3 and Figure 4 , a through hole is provided on the other side of the top of the installation frame 1. The other side of the top of the installation ring 33 is fixedly connected with a connecting rod 34, and the connecting rod 34 is slidably connected in the through hole. The top end of the connecting rod 34 is fixedly connected with the bottom of the connecting plate 31. The other side of the top of the installation ring 33 is fixedly connected with a spring 35, and the top end of the spring 35 is fixedly connected with the top of the inner wall of the installation frame 1, which facilitates preventing the installation ring 33 from descending and moving randomly.

[0036] Refer to Figure 5 , both sides of the scale 39 are fixedly connected with mounting plates 4, and the mounting plates 4 are connected to the installation ring 33 through threaded rods 5, which facilitates the staff to remove and replace the scale 39.

[0037] The implementation principle of an electric contact detector in an embodiment of this application is as follows: When it is necessary to detect the contact body 2, the first substrate 21 can be placed in the groove 6, and then the connecting plate 31 is pressed to drive the installation ring 33 to descend and move. The descending movement of the installation ring 33 can drive the slide plate 36 and the scale 39 to descend and move. When the installation ring 33 passes through the second substrate 22, the slide plate 36 abuts against the top of the second substrate 22. At this time, the slide plate 36 no longer descends and moves, while the installation ring 33 and the scale 39 continue to descend and move until the bottom of the installation ring 33 abuts against the top of the first substrate 21. At this time, through the value of the scale 39 pointed to by the pointer 38, it is possible to quickly measure whether the thickness of the second substrate 22 of the contact body 2 is qualified.

[0038] An embodiment of this application provides an electric contact detector. By setting the detection mechanism 3, when the staff detects the silver contact, it can quickly measure the thickness of the convex part of the silver contact, so as to facilitate the staff to quickly determine whether the thickness of the electric contact is qualified, reduce the operation steps, and thus facilitate improving the sampling inspection efficiency of the staff.
