Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit breaker detection, in particular to a squeezing type circuit breaker power-on test tooling. Background Art
[0002] With the development of the power Internet of Things, more and more intelligent miniature circuit breakers are used. The main difference between an intelligent miniature circuit breaker and an ordinary miniature circuit breaker is that it has changed from a single current fault protection to a comprehensive miniature circuit breaker integrating functions such as measurement, communication, control and protection.
[0003] During the production process of the circuit breaker, a power-on test is required. In the existing power-on test, generally, workers need to plug the circuit breaker into a fixed conductive column, and make the copper sheet in the interface of the circuit breaker abut against the conductive column to achieve power-on. In actual tests, there is a situation that after the conductive column is inserted into the interface of the circuit breaker, due to the gap between it and the interface, the conductive column cannot make good contact with the copper sheet in the interface, resulting in poor contact. Workers need to tilt the circuit breaker at a certain angle to ensure that the copper sheet in the interface can abut against the conductive column, which affects the test efficiency. Moreover, in the actual test process, in order to facilitate the repair of defective products detected, the power-on test is carried out before the shell riveting process of the circuit breaker. The shell that should be riveted and fixed will be temporarily fixed with a rubber band first, and then enter the riveting process after passing the detection. However, the pressure of the rubber band on the shell is limited, and the distance between each component in the shell is larger than that in the case of riveting, resulting in problems in detection. Workers need to press the shell tightly from both sides of the circuit breaker during the test, which consumes a large amount of physical strength of the workers and affects the test efficiency. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a squeezing type circuit breaker power-on test tooling, which can maintain good contact between the conductive column and the copper sheet in the interface of the circuit breaker during the power-on test of the circuit breaker, without the need for manual adjustment of the angle of the circuit breaker to facilitate the abutment of the copper sheet and the conductive column, and can maintain the pressing of the shell when the shell of the circuit breaker is not riveted, without the need for workers to manually press from both sides of the shell, reducing physical consumption and effectively improving the test efficiency.
[0005] To achieve the above object, the technical solution adopted by the utility model is as follows: An energization test tooling for an extrusion type circuit breaker, which includes a bottom plate. A conductive component and a housing clamping component are provided on the bottom plate. The conductive component includes a pair of conductive columns that cooperate with the circuit breaker interfaces. The conductive columns are rotatably arranged above the bottom plate, and an elastic member in insulated contact with the conductive columns is provided at one end thereof away from the circuit breaker. Through the elastic member, the end of the conductive column close to the circuit breaker is upturned. The housing clamping component includes a first positioning block and a second positioning block arranged in parallel on the bottom plate. An elastic plate is provided at the upper end of the first positioning block, and the elastic plate inclines towards the second positioning block. The circuit breaker is clamped between the elastic plate and the second positioning block.
[0006] A further improvement scheme of the utility model is that the conductive component includes an insulating shell. A rotating shaft is provided inside the insulating shell. An avoidance opening is provided on one side of the insulating shell. The two conductive columns are rotatably connected to the rotating shaft, one end thereof passes through the avoidance opening, and the other end is connected with a wire.
[0007] A further improvement scheme of the utility model is that the elastic member is a spring. A pair of screw holes are provided on the upper end surface of the insulating shell. Bolts are vertically threadedly connected in the screw holes. The two bolts and the two conductive columns are arranged in one-to-one correspondence, and the spring is provided between each group of bolts and the conductive column.
[0008] A further improvement scheme of the utility model is that an insulating sleeve is fixedly provided at the place where the conductive column abuts against the spring, and the spring abuts against the insulating sleeve.
[0009] A further improvement scheme of the utility model is that one end of the spring is fixedly connected with the bolt, and the other end is fixedly connected with the insulating sleeve.
[0010] A further improvement scheme of the utility model is that the distance between the first positioning block and the second positioning block is greater than the width of the circuit breaker and does not exceed 3 mm.
[0011] A further improvement scheme of the utility model is that the first positioning block and the second positioning block are arranged in a staggered manner.
[0012] A further improvement scheme of the utility model is that a protective cover is provided at the upper end of the insulating shell, and the part of the bolt located outside the insulating shell is located inside the protective cover.
[0013] The beneficial effects of the utility model are as follows:
[0014] In the present utility model, the conductive column is rotatably arranged above the bottom plate, and an elastic member in insulated contact therewith is provided at one end of the conductive column far away from the circuit breaker. Through the elastic member, one end of the conductive column close to the circuit breaker is upturned. After the conductive column is inserted into the circuit breaker interface, the end of the conductive column is always kept upturned through the elastic member, so as to keep in contact with the copper sheet on the upper end surface in the interface to achieve conduction. There is no need to manually adjust the angle of the circuit breaker, reducing the physical consumption of workers and improving the test efficiency.
[0015] In the present utility model, an elastic plate is provided at the upper end of the first positioning block. The elastic plate inclines towards the second positioning block. The circuit breaker is clamped between the elastic plate and the second positioning block. Through the cooperation of the elastic plate and the second positioning block, the unriveted circuit breaker housing can be pressed from both sides, so that the components therein keep good contact. Compared with the prior art, it is not necessary for workers to press the housing from both sides of the circuit breaker during testing, further reducing the physical consumption of workers and improving the test efficiency.
[0016] In the present utility model, by providing a bolt, the pre-tightening force of the spring can be adjusted by adjusting the depth of the bolt screwed into the insulating shell, and then the upturned degree of one end of the conductive column close to the circuit breaker can be adjusted. The adjustment speed is fast and it is convenient to adjust. Description of the Drawings

Detailed Embodiment
[0022] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments. Embodiment
[0023] Combined with Figures 1 to 3It can be known that an energization test tooling for a squeeze-type circuit breaker includes a bottom plate 1, on which a conductive component and a housing clamping component are provided. The conductive component includes a pair of conductive columns 2 that cooperate with the circuit breaker interfaces. The conductive columns 2 are rotatably arranged above the bottom plate 1, and an elastic member 3 that is in insulating contact with it is provided at the end away from the circuit breaker. Through the elastic member 3, the end of the conductive column 2 close to the circuit breaker is upturned. The housing clamping component includes a first positioning block 4 and a second positioning block 5 arranged in parallel on the bottom plate 1. An elastic plate 6 is provided at the upper end of the first positioning block 4, and the elastic plate 6 inclines towards the second positioning block 5. The circuit breaker is clamped between the elastic plate 6 and the second positioning block 5.
[0024] The conductive component includes an insulating shell 7. A rotating shaft 8 is provided inside the insulating shell 7. An avoidance opening 9 is provided on one side of the insulating shell 7. Two conductive columns 2 are rotatably connected to the rotating shaft 8, one end of which passes through the avoidance opening 9, and the other end is connected with a wire 10. The conductive column 2 passes through the avoidance opening 9 and abuts against the upper end wall of the avoidance opening 9 when not under pressure. At this time, the avoidance opening 9 also plays a limiting role in preventing the conductive column 2 from tilting upwards excessively.
[0025] The elastic member 3 is a spring. A pair of screw holes are provided on the upper end surface of the insulating shell 7. Bolts 11 are vertically threadedly connected in the screw holes. The two bolts 11 and the two conductive columns 2 are arranged in one-to-one correspondence, and a spring is provided between each group of bolts 11 and conductive columns 2.
[0026] An insulating sleeve 12 is fixedly provided at the place where the conductive column 2 abuts against the spring, and the spring abuts against the insulating sleeve 12.
[0027] Preferably, one end of the spring is fixedly connected to the bolt 11, and the other end is fixedly connected to the insulating sleeve 12. Preferably, both ends of the spring are fixedly connected to the bolt 11 and the insulating sleeve 12 by gluing.
[0028] Optionally, a first anti-detachment protrusion is provided on the lower end surface of the bolt part of the bolt 11, and a second anti-detachment protrusion corresponding to the first anti-detachment protrusion is provided on the lower end surface of the insulating shell 12. Both ends of the spring are respectively sleeved on the first anti-detachment protrusion and the second anti-detachment protrusion.
[0029] The distance between the first positioning block 4 and the second positioning block 5 is greater than the width of the circuit breaker and does not exceed 3 mm. When a rubber band is sleeved on the circuit breaker housing, the circuit breaker housing together with the rubber band is tightly fixed by the first positioning block 4 and the second positioning block 5 on both sides.
[0030] See Figure 3, Preferably, the elastic plate 6 is an arc-shaped plate with a bending angle less than 15°. Its lower end is connected to the first positioning block 4, and its upper end inclines towards the second positioning block 5. The elastic plate 6 has a certain elasticity and can be deformed and bent by an external force to facilitate the insertion of the circuit breaker between the first positioning block 4 and the second positioning block 5. After the external force is no longer applied, the elastic plate 6 resets and cooperates with the second positioning block 5 to clamp the circuit breaker. Optionally, the elastic plate 6 is made of polypropylene or polyurethane.
[0031] When inserting the circuit breaker between the first positioning block 4 and the second positioning block 5, the elastic plate 6 can be straightened and then the circuit breaker can be directly inserted. Or the circuit breaker can be tilted and inserted downward along the arc of the elastic plate and gradually pressed between the first positioning block 4 and the second positioning block 5. During this process, the elastic plate 6 is squeezed and deformed to facilitate the placement of the circuit breaker between the first positioning block 4 and the second positioning block 5, and its lower end face is placed on the bottom plate 1.
[0032] The first positioning block 4 and the second positioning block 5 are arranged in a staggered manner. It can position the circuit breaker from both sides and also from the front and back stagger on both sides of the circuit breaker, improving the fixing effect.
[0033] A protective cover 13 is provided at the upper end of the insulating shell 7, and the part of the bolt 11 outside the insulating shell 7 is located inside the protective cover 13. This improves the safety of the test. The insulating shell 7 is provided with a through-hole for the wire 10 to pass through.
[0034] The working principle of an extrusion-type circuit breaker power-on test tooling provided by the utility model is as follows: When in use, first connect the interface of the circuit breaker with the conductive column 2, insert the end of the conductive column 2 into the interface, and then gradually insert the circuit breaker between the first positioning block 4 and the second positioning block 5 until it is placed on the bottom plate 1. At this time, the elastic plate 6 cooperates with the second positioning block 5 to clamp and fix the circuit breaker from both sides of the circuit breaker housing, and the conductive column 2 makes the end inserted into the circuit breaker interface tilt upward through the elastic member 3 and abut against the copper sheet on the upper end face of the circuit breaker interface to achieve power-on.
