Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker testing equipment, and in particular to a circuit breaker testing device. Background Technology

[0002] When circuit breakers are tested, they are mostly tested by connecting them to a circuit breaker test bench. The circuit breaker is directly inserted into the test socket on the surface of the test bench, then fixed and tested. However, due to the inconsistency in the quality of circuit breakers, inferior products are easily damaged after being connected to power. The damaged fragments fall into the inside of the test socket. If not cleaned in time, the fragments can easily clog and damage the test socket of the test bench. Cleaning is a safety hazard because it is electrical equipment, while cleaning with the power off seriously affects the working efficiency of the equipment, making the existing circuit breaker testing devices inconvenient to use. Utility Model Content

[0003] To address the technical problem of circuit breaker fragments easily falling out within existing circuit breaker testing devices, this invention proposes a circuit breaker testing device.

[0004] This utility model discloses a circuit breaker testing device, including a tester. The surface of the tester has a test socket, and a protective mechanism is installed on the surface of the test socket. The protective mechanism includes a sleeve made of polyimide. A slot is provided on the rear surface of the sleeve, and the rear end of the sleeve is slidably inserted into the inner wall of the test socket. The tester is a circuit breaker test bench, and the sleeve is transparent to facilitate direct observation of the circuit breaker's test status.

[0005] Preferably, a sleeve is fixedly connected to both the upper and lower inner walls of the casing, and an electrical terminal is slidably inserted into both the upper and lower inner walls of the sleeve. Adjacent electrical terminals are connected by wires, and the ends of adjacent electrical terminals are located inside and outside the casing, respectively.

[0006] The above technical solution uses electrical terminals to connect the circuit of the tester to the circuit of the circuit breaker, thereby facilitating the testing of the circuit breaker. The electrical terminals are made of metal iron, which makes it easier for the electrical terminals to be attracted by a magnet.

[0007] Preferably, a mounting ring is fixedly connected to the inner wall of the middle part of the sleeve, and a thrust spring is fixedly connected to both the upper and lower surfaces of the mounting ring. The end of the thrust spring is fixedly connected to the surface of the electrical terminal.

[0008] The above technical solution utilizes a thrust spring for movable installation of the electrical terminals, thereby facilitating the extension of the electrical terminals from the sleeve.

[0009] Preferably, the upper and lower inner walls of the sleeve are provided with slots, and a connecting rod is slidably inserted into the inner wall of the slot, with a magnet fixedly connected to one end of the connecting rod.

[0010] The above technical solution uses a magnet to attract the electrical terminals, thereby facilitating the retraction of the electrical terminals into the sleeve.

[0011] Preferably, both the surface of the magnet and the surface of the connecting rod are provided with limiting grooves, and the sleeve is located inside the limiting groove.

[0012] The above technical solution utilizes a magnet to wrap around the sleeve through a limiting groove, thereby facilitating the movement of the magnet on the surface of the sleeve.

[0013] Preferably, a handle is fixedly connected to the other end surface of the connecting rod.

[0014] The above technical solution utilizes a handle to drive the connecting rod, thereby facilitating the movement of the magnet at the end of the connecting rod.

[0015] The beneficial effects of this utility model are as follows: By enclosing the circuit breaker with a protective mechanism and connecting the circuit breaker's circuit to the tester's circuit using terminals, the contact area between the circuit breaker and the tester is reduced. This reduces the likelihood of circuit breaker fragments flying into the test socket in the event of accidental circuit breaker failure, and also reduces the likelihood of fragments flying outwards at test personnel. Furthermore, the simple structure and ease of use make the protective mechanism effective in protecting both the test equipment and the test personnel. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 A circuit breaker testing device includes a tester 1. The surface of the tester 1 has a test socket 11. A protective mechanism is installed on the surface of the test socket 11. The protective mechanism includes a housing 2. The housing 2 is made of polyimide. A slot is opened on the rear surface of the housing 2. The rear end of the housing 2 is slidably inserted into the inner wall of the test socket 11. The tester 1 is a circuit breaker test bench, and the housing 2 is transparent to facilitate direct observation of the circuit breaker's test status.

[0020] To connect the circuit, sleeves 21 are fixedly connected to the upper and lower inner walls of the casing 2. Electrical terminals 22 are slidably inserted into the upper and lower inner walls of the sleeves 21. Adjacent electrical terminals 22 are connected by wires, with their ends located inside and outside the casing 2, respectively. The electrical terminals 22 are used to connect the circuit of the tester 1 to the circuit of the circuit breaker, facilitating the testing of the circuit breaker. The electrical terminals 22 are made of iron, making them easily attracted by the magnet 26. A mounting ring 23 is fixedly connected to the middle inner wall of the sleeve 21. Thrust springs 24 are fixedly connected to the upper and lower surfaces of the mounting ring 23. The ends of the thrust springs 24 are fixedly connected to the surfaces of the electrical terminals 22, allowing the electrical terminals 22 to be movably installed, thus facilitating their extension from the sleeve 21.

[0021] To control the installation of the circuit breaker, slots are provided on the upper and lower inner walls of the casing 2. A connecting rod 25 is slidably inserted into the inner wall of the slot. A magnet 26 is fixedly connected to one end of the connecting rod 25. The magnet 26 attracts the terminal 22, thereby facilitating the retraction of the terminal 22 into the sleeve 21. Limiting grooves 27 are provided on the surface of the magnet 26 and the surface of the connecting rod 25. The sleeve 21 is located inside the limiting groove 27. The magnet 26 wraps around the sleeve 21 through the limiting groove 27, thereby facilitating the movement of the magnet 26 on the surface of the sleeve 21.

[0022] By enclosing the circuit breaker with a protective mechanism and connecting the circuit breaker's circuit to the tester 1's circuit using the power terminal 22, the contact area between the circuit breaker and the tester 1 is reduced. This reduces the probability of circuit breaker fragments flying into the test socket 11 in the event of accidental circuit breaker failure, and also reduces the probability of fragments flying outwards at the test personnel. The structure is simple and easy to use, thus enabling the protective mechanism to effectively protect the test equipment and test personnel.

[0023] A handle 3 is fixedly connected to the other end of the connecting rod 25. The handle 3 is used to drive the connecting rod 25, which in turn facilitates the movement of the magnet 26 at the end of the connecting rod 25.

[0024] Working principle: In use, pull the handle 3 away from the housing 2. The handle 3 drives the magnet 26 through the connecting rod 25. The magnet 26 moves towards the surface of the housing 21 and attracts the terminal 22. Under the attraction of the magnetic force, the terminal 22 retracts into the housing 21. The thrust spring 24 is squeezed, inserting the circuit breaker into the housing 2. Then, insert the housing 2 together with the circuit breaker into the detection socket 11 on the surface of the tester 1. Push the handle 3 towards the surface of the housing 2. The connecting rod 25 pushes the magnet 26 away from the housing 21. The magnetic force on the terminal 22 decreases. The thrust spring 24 pushes the terminal 22 outward. The terminal 22 is inserted into the inside of the circuit breaker and the inside of the tester 1 respectively, connecting the circuit of the circuit breaker and the circuit of the tester 1. Then, the tester 1 performs the test.

[0025] After use, pull the handle 3 outward away from the casing 2. The power terminal 22 retracts into the casing 21 under the attraction of the magnetic force. The casing 2 drives the circuit breaker to be pulled out from the detection socket 11, and then the circuit breaker is pulled out from the casing 2.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
