Technical Field

[0001] This utility model relates to the field of new energy charging gun technology, specifically to an on-cable control and protection device with a modular adapter socket. Background Technology

[0002] With the rapid development of the new energy industry, new energy vehicles are gaining increasing market penetration due to their environmental protection and energy-saving advantages. As the number of new energy vehicles continues to rise, charging safety and convenience have become key factors restricting their further development and have attracted much attention from end users. Among them, the convenient home charging gun with cable control and protection device has become a common device for end users to charge new energy vehicles due to its flexibility and ease of operation.

[0003] For manufacturers, the safety and reliability of cable protection devices are of paramount importance, as they directly relate to the safety of users' lives and property during charging and the product's market reputation. At the same time, modular adapter sockets have significant advantages. They not only facilitate the company's platform-based design of products, enabling the common use of components and resource sharing among different products, but also reduce the difficulty of manufacturing, making it easier for enterprises to carry out unified management, thereby improving production efficiency and reducing costs.

[0004] In practical applications, the existing cable control and protection devices do not have a modular design for their adapter socket structure. This non-modular design leads to complex operation and cumbersome procedures during product assembly, requiring a lot of manpower and time, increasing the difficulty and cost of production, and also affecting the production efficiency and quality stability of the product.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-6 This utility model provides a technical solution: a cable control and protection device with a modular adapter socket, the structure of which includes a lower cover 1 and an upper cover 2. The upper cover 2 is snapped onto the top of the lower cover 1. A cable 3 is fixedly connected to one side of the interior of the lower cover 1. Multiple cables 3 are provided. An assembly port 4 is opened on one side of the lower cover 1. An adapter socket mechanism 5 is provided on one side of the lower cover 1. A charging plug 6 is provided on one side of the adapter socket mechanism 5. The adapter socket mechanism 5 includes a terminal frame 51. A terminal assembly 52 is provided inside the terminal frame 51. A socket housing 53 is inserted into one side of the terminal frame 51. A fixing groove 54 is opened on the outer surface of the socket housing 53. A socket sealing ring 55 is sleeved inside the fixing groove 54.

[0021] Among them, spring walls 56 are fixedly connected to both sides of the terminal frame 51, and a limiting plate 57 is fixedly connected to the top of the terminal frame 51. A pin hole is formed between the limiting plate 57 and the socket housing 53.

[0022] Among them, a fixing plate 58 is fixedly connected to one side of the inner side of the lower cover 1. There are two fixing plates 58, which are symmetrically distributed on one side of the assembly port 4. The spring wall 56 passes through the assembly port 4 and is snapped onto one side of the fixing plate 58.

[0023] The bottom of the upper cover 2 is fixedly connected with a pin 59, which is inserted into the pin hole.

[0024] Specifically, the assembled adapter socket is inserted into the lower cover 1 through the assembly port 4. At this time, the spring walls 56 on both sides are engaged with the two sides of the fixing plate 58 to form a primary fixation. Then, the upper cover 2 is inserted into the top of the lower cover 1, and the pin 59 is engaged with one side of the limiting plate 57, so that the pin 59 is inside the pin hole to form a secondary fixation. This prevents the adapter socket mechanism 5 from falling out of the lower cover 1, improves the stability of the adapter socket mechanism 5 in the lower cover 1, and also prevents the charging plug 6 from being pulled out when plugged in or unplugged.

[0025] The terminal assembly 52 includes a signal terminal 521, a ground terminal 522, and a power terminal 523. One side of the signal terminal 521, one side of the ground terminal 522, and one side of the power terminal 523 are all inserted into the interior of the terminal frame 51 and are fixedly connected to the cable 3 respectively. The other side of the signal terminal 521, the other side of the ground terminal 522, and the other side of the power terminal 523 are all inserted into the interior of the socket housing 53.

[0026] Among them, the surface of the signal terminal 521, the surface of the ground terminal 522, and the surface of the power terminal 523 are all provided with sealing grooves 524. The sealing grooves 524 are fitted with terminal sealing rings 525. Specifically, the sealing grooves 524 and terminal sealing rings 525 facilitate the installation of sealing structures on each terminal and form a sealing structure between each terminal and the terminal frame 51 to prevent water or dust from entering and damaging the internal components.

[0027] The charging plug 6 is inserted into the inside of the socket housing 53, and the signal terminal 521, ground terminal 522 and power terminal 523 are all electrically connected to the charging plug 6. The cable 3 is electrically connected to the circuit board in the lower cover 1. Specifically, this enables the adapter socket mechanism 5 to work normally and enables the charging plug 6 to work normally when inserted into the adapter socket.

[0028] Working principle: When assembling and using the modular adapter socket, first, insert the sealing ring into the sealing groove 524 so that the surface of the signal terminal 521, grounding terminal 522, and power terminal 523 is fitted with the terminal sealing ring 525. Then, crimp all terminals to the cable 3. Next, insert all terminals into the terminal frame 51. Insert the socket sealing ring 55 into the fixing groove 54 so that the surface of the socket housing 53 is fitted with the socket sealing ring 55. Then, install the assembled terminal frame 51 into the socket housing 53. Finally, insert the assembled adapter socket into the lower cover 1 through the assembly port 4. At this time, the spring walls 56 on both sides lock in place. The upper cover 2 is attached to both sides of the fixing plate 58 to form a primary fixation. Then, the upper cover 2 is inserted into the top of the lower cover 1, and the pin 59 is locked into one side of the limiting plate 57, so that the pin 59 is inside the pin hole, forming a secondary fixation to prevent the entire adapter socket mechanism 5 from falling out of the lower cover 1. Similarly, when the adapter socket mechanism needs to be removed and replaced, the upper cover 2 can be opened and the spring wall 56 can be retracted to remove and replace it. Thus, the modularly designed adapter socket mechanism 5 can be easily replaced and used. It is simple to assemble and easy to operate, and it forms a separate module that is independently connected to the control box, which facilitates modularization and standardization.
