Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a control unit test fixture. Background Technology

[0002] With the development of technology, control units, due to their small size and high performance, are increasingly used in the communications and power industries. Control unit technology is also becoming increasingly mature and sophisticated, greatly improving production efficiency. Meanwhile, batch testing technology for control units is gradually improving with market demand. However, batch testing of control units often involves a large number of units, and each control unit has a certain weight. While using screws or other fixing components to clamp and secure the control units ensures a firm grip, it results in a large workload for installation and disassembly, leading to long testing times and manpower costs, significantly reducing testing time and extending the testing cycle.

[0003] Therefore, how to quickly clamp the control unit and ensure its movement is the technical problem that needs to be considered and solved. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a control unit test fixture.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A control unit test fixture includes a secondary rod, the secondary rod having a left clamping portion, a lower left bracket connected to the lower end of the secondary rod at the left clamping portion, a main rod hinged to the upper side of the secondary rod, the main rod having a right clamping portion with a shape and specifications corresponding to the left clamping portion, and a lower right bracket connected to the lower end of the main rod at the right clamping portion;

[0007] A spring is installed between the secondary rod and the main rod, and the spring is located beside the hinge axis of the secondary rod and the main rod.

[0008] Furthermore, both the auxiliary rod and the main rod are provided with through holes, a design that facilitates quick replacement and installation of the spring.

[0009] Furthermore, the supporting surfaces of both the lower left bracket and the lower right bracket are flat. This design increases the contact area and ensures the stability of the control unit when clamped and placed.

[0010] Furthermore, the auxiliary rod and the lower left bracket are integrally formed, and the main rod and the lower right bracket are integrally formed. This design ensures strength and prevents problems such as loosening or shaking at the connection or weld breakage.

[0011] Furthermore, the hinge axis between the secondary rod and the main rod is a screw and nut mating structure. This design facilitates the adjustment of the rotational sensitivity after hinge.

[0012] The beneficial effects of using this utility model are as follows:

[0013] By adopting the structural design of this utility model, the control unit is directly placed between the left clamping part and the right clamping part. Under the effect of the spring, the control unit can be clamped and then moved for testing. It is simple, convenient and quick. Moreover, when it needs to be removed, only a force greater than the spring is needed, so disassembly is also quick and time-saving, ensuring testing efficiency and shortening the testing cycle.

[0014] This utility model has a reasonable structure, is simple to manufacture, and has low cost, so there will be no economic pressure in configuring and installing multiple units. It can also be quickly replaced after damage to maintain its use, making it suitable for mass production operations. Attached Figure Description

[0015] This utility model can be further illustrated by the non-limiting embodiments given in the accompanying drawings;

[0016] Figure 1 This is a schematic diagram of the structure of an embodiment of a control unit test fixture according to the present invention;

[0017] The symbols for the main components are explained below:

[0018] Sub-rod 1; Left clamping part 2; Lower left bracket 3; Main rod 4; Right clamping part 5; Lower right bracket 6; Spring 7; Through hole 8. Detailed Implementation

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, a control unit test fixture of the present invention includes a secondary rod 1, a left clamping part 2, a lower left bracket 3 connected to the lower end of the left clamping part 2, a main rod 4 hinged to the upper side of the secondary rod 1, a right clamping part 5 with a shape and specifications corresponding to the left clamping part 2, and a lower right bracket 6 connected to the lower end of the right clamping part 5.

[0021] A spring 7 is installed between the secondary rod 1 and the main rod 4. The spring 7 is located next to the hinge axis between the secondary rod 1 and the main rod 4.

[0022] In this embodiment, when using a control unit test fixture, with the hinge of the auxiliary rod 1 and the main rod 4 as the axis, moving the main rod 4 or the auxiliary rod 1 alone can move the left clamping part 2 and the right clamping part 5 away from each other, thereby opening up the space between them. Then, the control unit is placed directly between the left clamping part 2 and the right clamping part 5. Releasing the force on the main rod 4 or the auxiliary rod 1, under the effect of the spring 7, the left clamping part 2 and the right clamping part 5 move closer to each other. The left clamping part 2, together with the lower left bracket 3, supports the left side of the control unit, and the right clamping part 5, together with the lower right bracket 6, supports the right side of the control unit. This achieves the clamping of the control unit. Then, the main rod 4 can be lifted or a mechanical device can be used to move the main rod 4 to move the control unit to the test position.

[0023] Once the test position is reached, the control unit can be removed for testing simply by turning the lever. This is simple, convenient, and quick, saving time spent loading and unloading the control unit.

[0024] It is preferred that both the auxiliary rod 1 and the main rod 4 are provided with through holes 8. This design facilitates the quick replacement and installation of the spring 7. In fact, the structure for installing the spring 7 can also be considered depending on the specific situation.

[0025] Preferably, the supporting surfaces of the lower left bracket 3 and the lower right bracket 6 are both flat. This design increases the contact area and ensures the stability of the control unit when clamped. In fact, the width of the supporting surfaces of the lower left bracket 3 and the lower right bracket 6 can also be considered according to the specific situation.

[0026] The preferred design is to form the sub-rod 1 and the lower left bracket 3 as one piece, and the main rod 4 and the lower right bracket 6 as one piece. This design ensures strength and prevents problems such as loosening or wobbling at the connection or weld breakage. In fact, the connection structure between the sub-rod 1 and the lower left bracket 3, and between the main rod 4 and the lower right bracket 6 can also be considered depending on the specific situation.

[0027] The hinge shaft of the secondary rod 1 and the main rod 4 is preferably a screw and nut joint structure. This design is conducive to adjusting the rotation sensitivity after hinge. In fact, the hinge shaft structure of the secondary rod 1 and the main rod 4 can also be considered according to the specific situation.

[0028] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
