Description

Technical Field

[0001] This utility model relates to the field of power chargers, and more particularly to a charger for LLC power supplies. Background Technology

[0002] With the development of LLC power chargers, more and more chargers for LLC power are being used in the consumer electronics, new energy and transportation, as well as industrial and communication fields. The rational use of LLC power chargers can significantly improve charging efficiency, reduce size and increase convenience, and extend equipment life.

[0003] A power charger is disclosed in publication number CN219067909U, comprising a power charger body. The front of the power charger body has symmetrically symmetrically oriented connection holes. A connecting block is snapped into the center of the front of the power charger body through the connection holes. A connector is symmetrically fixedly mounted on the back of the connecting block. A limiting ring is fixedly fitted onto the outer surface of the connector. A first connecting wire is fixedly mounted on the center of the front of the connecting block, and a charger plug body is fixedly mounted at one end of the first connecting wire. In this solution, the power charger, by setting a limiting ring, first aligns the connector with the inside of the connection hole before the power charger body operates, so that the outer surface of the limiting ring fits against the inner wall of the connection hole. Because the limiting ring is made of rubber, it increases the friction between the power charger body and the charger plug body, thereby preventing the power charger body from separating from the charger plug body and ensuring the working efficiency of the device. Existing LLC power chargers typically use a single connection method without a fastening device, which can easily lead to loosening, detachment, poor contact, accelerated wear of the connector, and damage to the device port. Therefore, a charger for LLC power supplies is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a charger for LLC power supplies, which aims to improve the problems of loosening and poor contact, accelerated wear of connectors, and damage to device ports in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A charger for LLC power supply includes a housing 1, a housing 2 fixedly connected to the outer wall of the housing 1, a guide post 1 fixedly connected to the outer wall of the housing 2, and a clamping assembly provided at one end of the guide post 1.

[0007] The clamping assembly includes a limiting block, the outer wall of which is fixedly connected to one end of a guide post. A fixing plate is fixedly connected to the outer wall of the limiting block, and a fixing plate is fixedly connected to the outer wall of the limiting block. A threaded rod is threadedly connected inside the fixing plate and the fixing plate. A fixing post is threadedly connected to one end of the threaded rod, and a connecting post is threadedly connected to the other end of the threaded rod. An eccentric wheel is provided inside the connecting post, and a handle is fixedly connected to the outer wall of the connecting post.

[0008] As a further description of the above technical solution:

[0009] A connecting seat is provided on the outer wall of the outer shell, and a fixing column is fixedly connected inside the outer shell.

[0010] As a further description of the above technical solution:

[0011] A fixing column 2 is fixedly connected inside the outer shell 1, and a heat dissipation shell is provided on the outer wall of the outer shell 1.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the first guide post is slidably connected to the second guide post, the outer wall of the second guide post is provided with the second groove, and the outer wall of the second guide post is slidably connected to the ring.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the ring is fixedly connected with a buckle, and the outer wall of the outer shell has a groove.

[0016] As a further description of the above technical solution:

[0017] A plug is provided inside the outer casing.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the eccentric wheel is first loosened by pulling the handle, thereby loosening the limit block. The grounding connector is then inserted into the plug. When it needs to be fixed, the handle is pressed to lock it, thus achieving the effect of fixing the connection port, improving the stability of the connection, and solving the problems of loosening, falling off, and poor contact at the connection.

[0020] 2. In this utility model, by rotating the second guide post, it can be disengaged from the buckle in the ring and slide on the first guide post. When the required height is reached, it can be rotated and connected and fixed with the buckle, thus achieving the effect of telescopic guide post, improving the convenience of connection, and solving the limitations caused by different lengths.
