[0021] In order to make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following description of the specific embodiment of the present utility model will be described in detail in conjunction with the accompanying drawings of the specification.

[0022] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model may be implemented in other ways other than those described herein, and those skilled in the art may similarly promote the present utility model without violating the spirit of the present utility model, and therefore the present utility model is not limited to the specific embodiments disclosed herein.

[0023] Second, the term "an embodiment" or "embodiments" referred to herein refers to specific features, structures, or characteristics that may be included in at least one embodiment of the utility model. The phrase "in one embodiment" in various places throughout this specification does not always refer to the same embodiment, nor is it a separate or selective embodiment that excludes other embodiments. Embodiment 1

[0024] In the Fig. 1 to 3 show a first embodiment of the utility model, which has a connecting mechanism: Insertion component 100 comprising a guide block 101, a replacement connection opening 102 fixedly connected to an upper end of the guide block 101, and a sliding groove 103 open inside the guide block 101, a cavity 104 open inside the guide block 101, a first circular hole 105 open inside the guide block 101, a press assembly 106 adapted to be mounted inside the guide block 101, a snap assembly 107 adapted to be mounted on the outside of the guide block 101, a clamp assembly 108 adapted to be mounted on the outside of the snap assembly 107, a support assembly 109 adapted to be mounted on the lower end of the guide block 101, and a contact assembly 110 adapted to be mounted on the outside of the guide block 101 can be mounted; The material of the guide block 101 is iron to facilitate electrical conductivity.

[0025] In particular, the press assembly 106 includes an extrusion post 106a slidably connected within the guide block 101, a press plate 106b fixedly connected to the top of the extrusion post 106a, and a snap block 106c slidably connected within the press plate 106b; The material of the snap block 106c is provided as a magnet. Further, the press assembly 106 includes a limiting disk 106d fixedly connected to the outside of the extrusion post 106a and a spring 106e attached to the outside of the extrusion post 106a; wherein the spring 106e is provided inside the cavity 104 and the limiting disk 106d is provided inside the cavity 104.

[0026] The snap assembly 107 includes a side plate 107a provided on the outside of the guide block 101, a snap slot 107b provided inside the side plate 107a, an insertion slot 107c provided inside the side plate 107a, and a second circular hole 107d provided inside the side plate 107a.

[0027] It should be noted that the general-purpose relay calibration and display device uses 10 pairs of normally open contacts and 10 pairs of normally closed contacts to detect and display the circuit. The number of contacts is sufficient to meet most of the calibration work and can be expanded according to actual use. The device can not only turn the contact on and off, but also detect the contact resistance. Through the switching function, the display circuit adopts red LED indicator light, easy to identify and clearly display. The power supply adopts 24V human body safety voltage, and the circuit is connected in series with 1A insurance, which can be cut off in time in case of short circuit.

[0028] In use, the wiring is inserted into the interior of the first circular hole 105 through the second circular hole 107d, and after the wiring is inserted into the end of the first circular hole 105, the pressing plate 106b is pressed until the snap block 106c is aligned with the snap slot 107b. During this operation, the limiting plate 106d compresses the spring 106e, and since the snap block 106c is set to be made of a magnet and the guide block 101 is set to be made of iron, the snap block 106c snaps into the snap slot 107b under the action of magnetism, and at this time, the extrusion post 106a firmly compresses the wiring, so that the wiring is secured so that it is in contact with the guide block 101 and forms a closed circuit.

[0029] When removing the wiring, the rod pulls the snap block 106c out of the snap slot 107b, and under the action of the restoring force of the spring 106e, the press assembly 106 is returned to the initial position so that the wiring can be removed.

[0030] In summary, by inserting the wiring into the inside of the guide block 101 and pressing the pressing plate 106b, the snap block 106c is snapped into the snap slot 107b, so that the extrusion post 106a tightly presses the wiring and forms a closed circuit with the guide block 101, and when it is necessary to disassemble it, it is only necessary to pull out the snap block 106c and take out the wiring, which is simple and convenient to use. Embodiment 2

[0031] With reference to the Fig. 2 to 4, a second embodiment of the utility model is shown, which differs from the previous embodiment in that it provides a special operating method of the clamping device.

[0032] Specifically, the clamp assembly 108 includes a base plate 108a fixedly connected to the outside of the side plate 107a, a first arcuate groove 108b opening inside the base plate 108a, and a sliding plate 108c slidably connected to the outside of the side plate 107a, a second arcuate groove 108d opening inside the sliding plate 108c, and a tab 108e fixedly connected to the outside of the sliding plate 108c; wherein the curved surfaces of the first arcuate groove 108b and the second arcuate groove 108d are formed as rubber materials to prevent damage to the wire and achieve a better clamping effect.

[0033] Furthermore, the support assembly 109 comprises a first support plate 109a which is fixedly connected to the outer side of the side plate 107a, a vertical plate 109b which is fixedly connected to the upper side of the first support plate 109a, and a second support plate 109c which is fixedly connected to the outer side of the vertical plate 109b.

[0034] Furthermore, the contact assembly 110 comprises an upper contact block 110a slidably connected to the top of the guide block 101, an upper slider 110b fixedly connected to the lower end of the upper contact block 110a, and a threaded pin 110c screwed into the upper contact block 110a.

[0035] More specifically, the contact assembly 110 further includes a lower contact block 110d that is screwed to the outside of the threaded pin 110c, and a lower slide block 110e that is fixedly connected to the top of the lower contact block 110d.

[0036] In use, before inserting the wiring, it is necessary to operate the tab 108e so that the slide plate 108c slides upward, so that the two arcuate grooves of the first arcuate groove 108b and the second arcuate groove 108d form a circular shape, allowing the wiring to pass through. And when the pressing plate 106b is pressed down to the point where the snap block 106c is inserted into the interior of the snap slot 107b, the lower end of the snap block 106c presses the tab 108e, causing the tab 108e to slightly press the slide plate 108c downward, causing the rubber material on the surface of the first arcuate groove 108b and the second arcuate groove 108d to tightly enclose the wiring, thereby achieving a more stable wiring clamping effect.

[0037] When it is necessary to remove the wires, the snap block 106c is pulled out so that after the press assembly 106 is reset, the snap block 106c no longer presses tightly on the tab 108e and the first arcuate groove 108b and the second arcuate groove 108d no longer tightly enclose the wires to facilitate the removal of the wires, and after the removal of the wires, the slide plate 108c is returned to the starting position under the action of gravity.

[0038] Furthermore, when the relay is detected, the distance between the upper contact block 110a and the lower contact block 110d can be controlled by rotating the sliding plate 108c. As the distance increases, the contact assembly 110 can be switched so that the contact assembly 110 is only connected at the junction with one of the guide blocks 101 and not at the junction with the other guide block 101, thereby breaking the circuit. It is also possible to switch the contact assembly 110 so that the contact assembly 110 contacts both guide blocks 101, thus opening the circuit.

[0039] In summary, the mutual cooperation of the press assembly 106, the snap assembly 107, and the clamp assembly 108 can achieve that when the wiring is not connected, the sliding plate 108c is intertwined with the base plate 108a, thereby sealing the second circular hole 107d so that no contaminants can enter, thereby protecting the test terminal.

[0040] When wiring is required, the wiring can be connected to the circuit by simply sliding the sliding plate 108c, inserting the wiring, and pressing the pressing plate 106b, which is easy to operate, and by using the two arc grooves to strengthen the pressure and make the wiring more stable. Embodiment 3

[0041] With reference to the Fig. 1, Fig. 2 and Fig.Figure 4 shows a third embodiment of the utility model, which differs from the previous embodiment in that the embodiment provides a test terminal with a connecting mechanism and a spacer mechanism 200. It includes a spacer 201 provided on the outside of the side plate 107a, an insertion post 202 fixedly connected to the outside of the spacer 201, and a protective element 203 that can be attached to the outside of the side plate 107a. wherein the insertion post 202 is adapted to be mounted inside the insertion slot 107c.

[0042] In particular, the protective element 203 comprises a transverse slot 203a opened within the spacer 201 and a transverse plate 203b slidably connected within the transverse slot 203a.

[0043] When it is not necessary to connect the spare connection opening 102 during use, simply slide the cross plate 203b into the cross slot 203a at the top of the spare connection opening 102, thereby closing the spare connection opening 102 to prevent contaminants from entering the spare connection opening 102 and to protect the device. When wiring is required, simply slide the cross plate 203b so that the cross plate 203b no longer closes the spare connection opening 102, and wiring can be performed normally.

[0044] In summary, by sliding the cross plate 203b to move within the cross slot 203a and controlling whether the cross plate 203b closes the spare connection opening 102 or not, it can be realized that when wiring is required, the cross plate 203b is moved so that the spare connection opening 102 is not closed, and when wiring is not required, the cross plate 203b is moved so that the spare connection opening 102 is closed to achieve the effect of protecting the device.
