In addition, the heat dissipation effect of the rectifier bridge is not good, and the service life is likely to be short. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rectifier bridge base to solve the related problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rectifier bridge base includes a mounting base, a rectifier base body, and heat-conducting fins. The rectifier base body is provided at the top end of the mounting base, and a heat-conducting tube is provided at the bottom end of the rectifier base body.

[0011] Compared with the prior art, the present utility model provides a rectifier bridge base, which has the following beneficial effects:

[0012] 1. In the present utility model, the rectifier base body squeezes the upper position of the moving block, so that the moving block drives the position of the pull rod to move inside the activity groove and squeezes the return spring. When the rectifier base body moves downward to align with the groove position and the moving block position, under the action of the self-elastic force of the return spring, the moving block is driven to insert into the groove position of the rectifier base body, thereby further fixing the position of the rectifier base body at the mounting base.

[0013] 2. In the present utility model, the position of the rectifier base body is quickly positioned and fixed with the mounting base. When the rectifier base body fits with the mounting base, it first fits with the heat conduction tube to absorb heat, and at the same time dissipates heat through the heat conduction fins.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1, as Figure 1-2 shown, the present utility model provides a technical solution: a rectifier bridge base, including an installation base 1, a rectifier base body 2 and heat dissipation fins 4. The top end of the installation base 1 is provided with the rectifier base body 2, and a heat conduction tube 3 is provided at the bottom end of the rectifier base body 2. The bottom end of the installation base 1 is provided with heat dissipation fins 4, and heat dissipation holes 5 are opened inside the heat dissipation fins 4. A positioning mechanism for positioning the position of the rectifier base body 2 is provided at the top end of the installation base 1. The positioning mechanism includes an elastic piece 7 and a positioning block 8. A plurality of elastic pieces 7 are provided on the inner wall of the installation base 1, and a positioning block 8 is provided on the outer wall of the elastic piece 7. When the rectifier base body 2 is inserted into the installation base 1 for installation, first, the lower part of the rectifier base body 2 contacts and presses against the position of the positioning block 8, so that the elastic piece 7 is tightened, and then the rectifier base body 2 is fixed at the installation base 1. This structure facilitates the quick positioning and fixing of the position of the rectifier base body 2 and the installation base 1. When the rectifier base body 2 is attached to the installation base 1, it first contacts and absorbs heat with the heat conduction tube 3, and at the same time dissipates heat through the position of the heat dissipation fins 4, and further dissipates heat from the heat dissipation fins 4 through the heat dissipation holes 5. This structure is simple to operate and convenient to use.

[0021] Embodiment 2, as Figure 1-4 shown, the present utility model provides a technical solution: a rectifier bridge base, including an activity groove 9 opened on the inner wall of the installation base 1, and an installation mechanism for fixing the position of the rectifier base body 2 is arranged inside the activity groove 9. The installation mechanism includes a pull rod 10 and a moving block 11. The pull rod 10 is arranged inside the activity groove 9, and a moving block 11 penetrating through the rectifier base body 2 is installed on one side of the pull rod 10. A return spring 12 is sleeved on the outer wall of the pull rod 10, and both sides of the return spring 12 are respectively in contact with the activity groove 9 and one side of the pull rod 10. A lead wire 6 is arranged at the top end of the rectifier base body 2. By pressing the upper position of the moving block 11 by the rectifier base body 2, the moving block 11 drives the position of the pull rod 10 to move inside the activity groove 9 to compress the return spring 12. When the rectifier base body 2 moves downward to align with the position of the moving block 11 at the groove position, the moving block 11 is driven by the self-elastic force of the return spring 12 to insert into the groove position of the rectifier base body 2, thereby further fixing the position of the rectifier base body 2 at the installation base 1.

[0022] Working principle: When the rectifier base body 2 is inserted into the mounting base 1 for installation, first, when the rectifier base body 2 contacts and presses against the positioning block 8 below, the elastic piece 7 is tightened, and then the rectifier base body 2 is fixed at the mounting base 1. This structure facilitates the rapid positioning and fixing of the position of the rectifier base body 2 and the mounting base 1. When the rectifier base body 2 fits with the mounting base 1, it first fits with the heat conduction tube 3 to absorb heat, and at the same time dissipates heat through the heat conduction fins 4, and further dissipates heat from the heat conduction fins 4 through the heat dissipation holes 5. This structure is simple to operate and has good heat dissipation performance. By pressing the upper position of the moving block 11 by the rectifier base body 2, the moving block 11 drives the position of the pull rod 10 to move inside the movable groove 9 and presses against the reset spring 12. When the rectifier base body 2 moves downward to align with the moving block 11 at the groove position, under the action of the self-elastic force of the reset spring 12, the moving block 11 is driven to insert into the groove position of the rectifier base body 2, thereby further fixing the position of the rectifier base body 2 at the mounting base 1;

[0023] When it needs to be removed, pull the pull rod 10 outward to drive the moving block 11 to separate from the rectifier base body 2, and then pull the rectifier base body 2 upward to remove it.

[0024] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art does not depart from the essence and scope of the technical solution of the present invention.
