Its core function is to convert electromagnetic force into mechanical force to achieve remote or automatic control of power equipment such as circuit breakers and disconnectors. This module is not only responsible for accurately controlling the closing and opening actions of power equipment, but also bears the responsibility of real-time monitoring of the operating status of the equipment to ensure the smooth operation of power equipment. As a key link in the electrical connection of the power system, the electric control module plays a vital role and is an essential component to ensure the stable operation of power equipment.

[0003] Before leaving the factory, the electric control module must go through a strict and comprehensive testing process. The testing equipment consists of a host and a fixture. The host is equipped with an operation unit and a display unit on top, and the power supply circuit, voltage and current detection unit, resistance detection unit, critical value detection unit, contact connection detection unit, electrical connection loop detection unit and contact switching delay detection unit are integrated inside. The fixture is equipped with components for product testing and corresponding clamping structures for finished products and semi-finished products. The host and the fixture are connected by cables, so that the electric control module can be fully tested.

[0004] However, the traditional testing method has many shortcomings. When testing the electric control module, the electric control module needs to be fixed on the fixture, and then the electric control module is tested using a tester. However, the existing fixture clamping method is complicated and inconvenient to operate, which affects the work efficiency of the staff. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-5As shown, an electric operation module test fixture of the utility model comprises a bottom plate 1, vertical rods 101 are arranged on the left and right sides of the bottom plate 1, the upper ends of the two vertical rods 101 are arranged on the side away from each other with a first inclined surface 11, the outer surfaces of the two vertical rods 101 are sleeved with sleeves 12, the upper ends of the two sleeves 12 are arranged with mounting plates 13, a supporting mechanism is arranged between the two mounting plates 13, the two mounting plates 13 are arranged with slide grooves 14, and the upper sides of the two mounting plates 13 are arranged with extension grooves 1 connected to the slide grooves 14. 41, the openings of the two slide grooves 14 are arranged opposite to each other, the lower inner walls of the two slide grooves 14 are provided with through holes 15 connected to the sleeve 12, the two slide grooves 14 are slidably equipped with pressure plates 16, and a rebound mechanism is provided between the two pressure plates 16 and the mounting plate 13. The middle sides of the two pressure plates 16 are provided with limiting grooves 17 matching the positions of the through holes 15, the limiting grooves 17 are provided with second inclined surfaces 18 matching the first inclined surfaces 11, and the opposite sides of the two pressure plates 16 are provided with third inclined surfaces 19 arranged upward.

[0029] When the electric control module needs to be tested, the staff presses the electric control module downward between the two mounting plates 13. When the electric control module is pressed downward, the two ends of the electric control module will first contact the third inclined planes 19 on the left and right sides. When the electric control module continues to move downward, under the guidance of the third inclined plane 19, the two pressure plates 16 are pushed away from each other at the same time. The two pressure plates 16 slide in the slide groove 14. At this time, the rebound mechanism begins to compress. At this time, since the second inclined plane 18 contacts the first inclined plane 11, the second inclined plane 18 moves downward under the guidance of the first inclined plane 11. Therefore, when the two pressure plates 16 move away from each other, the two pressure plates 16 and the two mounting plates 13 move downward relative to the vertical rod 101, and the vertical rod 101 drives the sleeve 12 to move downward until the electric control module moves to the two pressure plates. The lower side of the plate 16 falls on the supporting mechanism. At this time, the two pressing plates 16 are driven to approach each other under the action of the extension of the rebound mechanism. When the two pressing plates 16 are close to each other, the ends of the two pressing plates 16 can clamp and limit the electric control module. When the two pressing plates 16 are close to each other, under the guidance of the first inclined surface 11, the pressing plate 16 contacts the first inclined surface 11 through the second inclined surface 18, and the pressing plate 16, the mounting plate 13 and the sleeve 12 move upward and reset at the same time. At this time, the test of the electric control module is completed. The power supply circuit, voltage and current detection unit, resistance detection unit, critical value detection unit, contact connection detection unit, electrical connection loop detection unit and contact switching delay detection unit in the test host are used to perform a comprehensive test on the electric control module to control the factory quality of the electric control module.

[0030] When the staff needs to take out the electric control module, they can press down the mounting plate 13 again, and similarly, drive the left and right pressing plates 16 to slide and be received in the slide groove 14 until the end of the pressing plate 16 moves out from the upper side of the electric control module, and the staff can freely take out the electric control module;

[0031] When the staff performs the clamping work, they press the electric control module downward. When the electric control module is tested, a plurality of spring ejectors are installed on the lower surface of the electric control module. When the electric control module is pressed downward to install, the spring ejectors are in a compressed state. When the two pressure plates 16 block the electric control module, the electric control module can be ejected under the extension of the spring ejectors, and the staff can take the electric control module conveniently and quickly.

[0032] To sum up, when installing the electric control module, the present design scheme only needs to press down the electric control module to achieve the effect, and when installing and removing the electric control module, the two mounting plates 13 automatically move downward. This design can keep the electric control module away from the test probe of the test equipment when loading and unloading the electric control module, making it easier for the staff to take it by hand.

[0033] The supporting mechanism includes two supporting rods 2 , which are respectively located at the front and rear sides of the mounting plate 13 , and the two ends of the two supporting rods 2 are respectively connected to the two mounting plates 13 .

[0034] When the electric control module falls on the upper surfaces of the two support rods 2, the electric control module can be limited by clamping the ends of the two pressing plates 16.

[0035] The upper surfaces of the two support rods 2 are provided with protective pads. The design of the protective pads can protect the outer surface of the electric control module when the electric control module falls on the upper surface of the support rod 2, preventing the support rod 2 from scratching the outer surface of the electric control module.

[0036] The rebound mechanism includes mounting grooves 21 arranged on the front and rear sides of the pressure plate, and slide bars 22 are arranged in the two mounting grooves 21. Springs 23 are sleeved on the outer surfaces of the two slide bars 22. A fixed block 24 sleeved on the outer surface of the slide bar 22 is arranged on the side of the two mounting grooves 21 away from the center of the two mounting plates 13, and the upper end of the fixed block 24 is connected to the upper inner wall of the slide groove 14.

[0037] When the two pressure plates 16 move away from each other and slide into the slide groove 14, since the fixing block 24 is connected to the mounting plate 13, the position of the pressure plate 16 is stationary relative to the pressure plate 16 during the sliding process. In this way, the spring 23 is compressed by the fixing block 24. When the two pressure plates 16 need to move closer to each other and reset, the spring 23 can be extended to drive the two pressure plates 16 to move closer to each other.

[0038] The inner walls at both the front and rear sides of the two slide grooves 14 are provided with blocking grooves 25 , and blocking blocks 26 connected to the pressing plate 16 are slidably mounted in the blocking grooves 25 .

[0039] When the pressing plate 16 slides in the slide groove 14, it drives the blocking block 26 to slide in the blocking groove 25. The design of the blocking block 26 can limit the sliding of the pressing plate 16 to prevent the pressing plate 16 from completely moving out of the blocking groove 25. The inner walls on the left and right sides of the blocking groove 25 are the limit distances of the left and right sliding positions of the pressing plate 16.

[0040] The lower surfaces of the two sleeves 12 are provided with cushions. The design of the cushions can protect the lower ends of the sleeves 12.

[0041] The four corners of the bottom plate 1 are provided with positioning holes 27. The design of the four positioning holes 27 facilitates the staff to install the fixture on the test bench.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
