Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and specifically relates to a new type of power terminal connector. Background Art

[0002] Power terminal connectors are a type of connector specifically used for transmitting high-power electrical signals. They are usually used to connect large electrical equipment or high-power power systems, such as mechanical equipment, motors, generators, and industrial automation systems, etc.

[0003] Currently, the power terminal connectors on the market (as shown in Figure 8 ) include a socket body and a plug body that can be inserted into each other. Among them, an insertion hole (mating frame opening) for inserting the plug body is reserved on the socket body. Due to the relatively large aperture of the insertion hole, there is a risk of accidental finger contact. Secondly, it does not meet the IP20 level of protection; secondly, in terms of mating applications, both the socket plastic shell (i.e., the position of the mating frame opening) and the male pins are prone to deformation, resulting in poor product consistency and unstable contact.

[0004] In view of this, a new type of power terminal connector is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a new type of power terminal connector to solve the above-mentioned problems.

[0006] The technical solution adopted by the utility model is as follows: A new type of power terminal connector includes a socket body and a plug body that can be inserted into each other; the socket body includes a socket housing, a socket male pin module and socket pins inserted on the socket housing. A plurality of partitions are equidistantly arranged along the length direction at the insertion end of the socket housing and are separated into a plurality of insertion hole positions by the plurality of partitions; the plug body includes a plug housing, a plug cover plate and a socket female pin module inserted inside the plug housing. A plurality of guiding grooves are equidistantly opened along the length direction at the insertion end of the plug housing and are separated into a plurality of insertion parts adapted to the insertion hole positions by the guiding grooves; when the plug body is inserted on the socket body, the plurality of guiding grooves are correspondingly inserted into the partitions.

[0007] In a preferred embodiment, a plurality of limiting protrusions are formed by the insertion part of the plug housing protruding upwards, and limiting grooves adapted to the insertion of the limiting protrusions are opened on the socket housing. The limiting protrusions are in a wedge shape.

[0008] In a preferred embodiment, the socket male pin module includes a plurality of socket male pins. One ends of the plurality of socket male pins are correspondingly inserted into a plurality of insertion hole positions of the socket housing. The other ends of the socket male pins are bent to form a limiting edge, and a slot for the insertion of the limiting edge is opened on the upper end wall of the socket housing.

[0009] In a preferred embodiment, protective baffles are formed protruding from the upper end surface of the socket housing between every two of the slots.

[0010] In a preferred embodiment, a guiding edge is formed by bending the bottom wall at the other end of the plug housing towards the opposite end, and an accommodating space for inserting the plug cover plate is formed by enclosing between the plug housing and the guiding edge.

[0011] In a preferred embodiment, a plurality of limiting convex surfaces are equidistantly arranged on the upper end wall of the plug cover plate, and limiting holes for the limiting convex surfaces to be snapped into are correspondingly formed on the upper end wall of the plug housing.

[0012] To sum up, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, socket partitions and plug guiding grooves are respectively designed and added on the socket body and the plug body, which can separately isolate each male and female pin, meet the IP20 standard. Secondly, after separation, the size of the leading-in end becomes smaller, which can avoid the electric shock risk caused by accidental touch of human hands in the live state, making it safer. At the same time, the added socket partitions can strengthen the socket structure, effectively control the deformation of the mating frame opening, make the product more stable, and solve the problems of easy deformation of the socket housing and poor product consistency;

[0014] 2. In the present utility model, a protective baffle extending outward is additionally designed on the end face of the socket male pin on the socket body, which improves the electrical clearance and creepage distance, thereby enhancing the electrical performance;

[0015] 3. In the present utility model, the socket male pin is bent and then pressed onto the socket housing, and slots for embedding the bent part of the socket male pin are reserved on the socket housing, so that the installation position of the pin is easy to control and not easy to deform.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Refer to Figures 1-8 , a novel power terminal connector, comprising a socket body 2 and a plug body 1 that can be inserted into each other; the socket body 2 includes a socket housing 22, a male socket pin module 23 and socket stands 21 inserted on the socket housing 22. A plurality of partitions 221 are equidistantly arranged along the length direction at the insertion end of the socket housing 22 and are separated into a plurality of insertion holes by the plurality of partitions 221. The plug body 1 includes a plug housing 11, a plug cover plate 13 and a female socket pin module 12 inserted inside the plug housing 11. A plurality of guiding grooves 111 are equidistantly formed along the length direction at the insertion end of the plug housing 11 and are separated into a plurality of insertion parts adapted to the insertion holes by the guiding grooves 111; when the plug body 1 is inserted into the socket body 2, the plurality of guiding grooves 111 are correspondingly inserted into the partitions 221. By respectively designing and adding partitions 221 and guiding grooves 111 on the socket body 2 and the plug body 1, each male and female pin can be separately separated, which can meet the IP20 standard. Secondly, after separation, the hole size at the insertion end becomes smaller, which can avoid the electric shock risk caused by accidental touch of the human hand in the live state and is safer.

[0027] At the same time, the added partitions 221 can strengthen the socket structure, effectively control the deformation of the mating frame opening, make the product more stable, and solve the problems of easy deformation of the socket housing 11 and poor product consistency.

[0028] Furthermore, a plurality of limiting protrusions 1a are formed by upward protrusion of the insertion part of the plug housing 11. Limiting grooves 2b adapted for the limiting protrusions 1a to be snapped into are formed on the socket housing 22. The limiting protrusions 1a are in a wedge shape. Through the cooperation of the limiting protrusions 1a and the limiting grooves 2b, the strength after the socket body 2 and the plug body 1 are inserted into each other can be ensured, and problems such as easy detachment are not likely to occur.

[0029] Among them, the limiting protrusions 1a are preferably made of a plastic material with a certain elasticity, which is not limited herein.

[0030] Furthermore, the male socket pin module 23 includes a plurality of male socket pins. One ends of the plurality of male socket pins are correspondingly inserted into a plurality of inlet holes of the socket housing 22. The other ends of the male socket pins are bent to form limiting edges. A slot 222 for the limiting edges to be embedded is formed on the upper end wall of the socket housing 22. After the male socket pins are bent, they are pressed onto the socket housing 22, and a slot 222 for the bent parts of the male socket pins to be embedded is reserved on the socket housing 22, so that the installation positions of the male socket pin pins are easy to control and are not likely to be deformed.

[0031] Furthermore, a protective baffle 223 is formed by protrusion on the upper end surface of the socket housing 22 between two adjacent slots 222. A protective baffle 223 extending outward is additionally designed on the end surface of the male socket pins on the socket body 2, so that the electrical clearance and creepage distance are increased, thereby improving the electrical performance.

[0032] Furthermore, a guiding edge 112 is formed by bending the bottom wall of the other end of the plug housing 11 towards the opposite end. A receiving space for the plug cover plate 13 to be inserted is formed by surrounding between the plug housing 11 and the guiding edge 112. A plurality of limiting convex surfaces 131 are equidistantly arranged on the upper end wall of the plug cover plate 13. Corresponding limiting holes 113 for the limiting convex surfaces 131 to be snapped into are formed on the upper end wall of the plug housing 11. The traditional rotary mounting cover plate is changed to a direct insertion cover plate. The plug cover plate 13 is inserted into the receiving space and fixed by snap-fitting, which is convenient for automatic equipment to grasp and assemble, and improves the production yield of the product.

[0033] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
