Description

Technical Field

[0001] This invention relates to electrical connector kits, and more particularly to mating and fixing structures therein. Background Technology

[0002] Existing electrical connectors typically include male and female connectors. When the male and female connectors are mated, the cables of both are connected to achieve an electrical connection. The basic connection structure and method involves using conductive springs to clamp conductive pins to achieve the electrical connection. Corresponding snap-fit ​​structures are also present on the male and female connectors to maintain a stable connection. However, snap-fit ​​structures require more steps to assemble and disassemble, making them cumbersome to use. Summary of the Invention

[0003] The purpose of this invention is to improve and innovate upon at least one of the shortcomings or problems existing in the prior art, and to provide an electrical connector kit that can be quickly switched on and off.

[0004] The technical solution of the present invention is to construct an electrical connector kit, including a male connector and a female connector;

[0005] The male connector includes a first base and a protrusion mounted on the first base. The protrusion is a columnar structure with a cross-section of a circle, ellipse, crescent, fan, or polygon. The end away from the first base is a convex surface. The protrusion and the first base are provided with a plurality of first mounting holes that pass through them. Each first mounting hole is provided with a conductive post. The end of the conductive post near the convex surface is aligned with the convex surface or is contained within the protrusion.

[0006] The female head includes a second base, one end of which is provided with a groove. The groove can cooperate with the protrusion. The first base is provided with a number of connecting grooves and a through second mounting hole. Each second mounting hole is provided with a flexible conductive pin. The conductive pin extends into the groove. When the protrusion and the groove are engaged, the conductive pin and the conductive post correspond one-to-one.

[0007] The male and female connectors are provided with a movable connector at their mating points.

[0008] In one embodiment, the end of the protrusion away from the first base is a flat or curved surface, and the corresponding surface of the groove is also a flat or curved surface.

[0009] In one embodiment, the end of the protrusion away from the first base is formed by splicing together at least two planes, and the corresponding surface of the groove is also formed by splicing together planes.

[0010] In one embodiment, the end face of the protrusion away from the first base is a conical surface composed of multiple triangular faces, the number of which is equal to the number of sides of the cross-sectional polygon of the protrusion, and the corresponding face of the groove is also composed of multiple triangular faces.

[0011] The polygons mentioned are equilateral triangles, squares, regular pentagons, or regular hexagons.

[0012] The outer wall of the protrusion is provided with a key strip or keyway, and correspondingly, the inner wall of the groove is provided with a matching keyway or key strip.

[0013] The movable connector is a magnet. When the male and female heads are connected, the magnets on the male and female heads correspond one-to-one and their opposite faces have opposite polarities.

[0014] The magnet is disposed on the first base and the second base, or disposed at the end of the protrusion and the bottom of the groove.

[0015] The first and second bases are cylindrical or cubic.

[0016] Advantages and beneficial effects of this invention: This invention features a male and female connector that connect magnetically. The electrical connection between the male and female connectors is an elastic contact, which makes mating and disassembly more convenient and faster compared to the pins and clamps used in existing technologies. The crescent-shaped protrusion on the male connector naturally provides a foolproof function, and other shapes also achieve foolproof functionality through key strips and keyways. When used for charging and electrical connection of smart boxes, this invention can achieve simultaneous connection of multiple cables. Because the head of the conductive pin on the female connector is located within the groove, it ensures that the conductive pin will not protrude after installation, preventing damage from the external environment. Similarly, the end of the conductive post on the protrusion does not protrude from the protrusion, avoiding short-circuit damage from contact with external conductors. Attached Figure Description

[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0024] It should be noted that when an element is considered to be "set" on another element, it can be directly set on or connected to the other element, or an intermediate element may be present simultaneously. The terms "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for descriptive purposes only and is not intended to limit the invention. Example 1

[0026] like Figure 1-3 As shown, an electrical connector kit includes a male connector 1 and a female connector 2.

[0027] The male connector 1 includes a first base 11 and a protrusion 12 mounted on the first base 11. The protrusion 12 is a columnar structure with a hexagonal cross-section. The end away from the first base 11 is a convex surface, which is a conical surface spliced ​​together by six triangular faces. The protrusion 12 and the first base 11 are provided with six first mounting holes 13 that pass through them. Each first mounting hole 13 is provided with a conductive post 14. The end of the conductive post 14 near the convex surface is retracted into the protrusion 12.

[0028] The female head 2 includes a second base 21, one end of which is provided with a groove 22. The groove 22 can cooperate with the protrusion 12. The second base 21 is provided with six second mounting holes 23 that connect the grooves 22 and pass through each other. Each second mounting hole 23 is provided with a spring conductive pin 24. The spring conductive pin 24 extends into the groove 22. When the protrusion 12 cooperates with the groove 22, the spring conductive pin 24 and the conductive post 14 correspond one-to-one and are in elastic compression contact.

[0029] The male connector 1 and the female connector 2 are provided with a movable connector 3 at the joint. In this embodiment, the movable connector is a magnet. The magnets on the male connector 1 and the female connector 2 have opposite polarities on their opposite sides, and they can be attracted together after they come into contact.

[0030] After the protrusion 12 is inserted into the groove 22, the magnet fixes the male head 1 and the female head 2 in place, and the end of the spring conductive pin 24 is in close contact with the end of the conductive post 14, thus achieving electrical connection. When it is necessary to disconnect, the male head and the female head can be pulled apart by external force. Example 2

[0031] like Figure 4 As shown, unlike Embodiment 1, the convex surface of the protrusion 12 in this embodiment is an arc surface, and the bottom of the corresponding groove is also an arc surface. Example 3

[0032] like Figure 5 As shown, the cross-sections of the protrusions and grooves in this embodiment are equilateral triangles. Example 4

[0033] like Figure 6 As shown, the cross-sections of the protrusions and grooves in this embodiment are square.

[0034] The cross-sections of the bumps and grooves can also be set into other shapes, such as regular pentagons, sectors, crescents, or ellipses. Among them, non-rotationally symmetric shapes such as crescents and sectors have their own error-proof effect. For bumps and grooves with rotationally symmetric (including centrally symmetric) shapes, corresponding key strips 4 and keyways 5 should also be provided to restrict the rotation of each side, ensure the unique correspondence between the spring pin and the conductive post, and prevent incorrect wire connection.

[0035] Of course, the convex surface of the bump in the foregoing embodiments can be set as a conical surface spliced ​​from multiple planes, or as an arc surface. The bottom of the groove can also be set as a corresponding shape to form a fit.

[0036] To increase the contact area and thus improve conductivity, the contact ends of the conductive post 14 and the conductive pin 24 can be respectively provided with an arc-shaped concave surface and an arc-shaped convex surface, such as... Figure 3 , Figure 4 As shown in the image.

[0037] In this invention, because the protrusions and grooves are positioned to limit relative rotation, conductive posts and conductive pins can be arranged more densely. A single connector kit can be used to connect multiple cables in a small space without worrying about misaligning the wires. If the actual number of conductive posts and pins installed is small, there is still considerable space at the corresponding positions of the protrusions and grooves, allowing for the placement of movable connectors such as magnets at these positions.

[0038] In the embodiment, both the first base and the second base are cylindrical. In practice, they can also be set as cubes or columnar structures with other cross-sectional shapes as needed to ensure that the male and female heads can be connected by movable connectors after connection, making it convenient to install the male and female heads on the device (such as a box).

[0039] This invention uses magnetic force to connect the male and female connectors and elastic pins to achieve electrical connection. Connection and disassembly are very convenient. After disassembly, the electrical contacts are retracted within the male or female connector, preventing the conductive posts and spring-loaded conductive pins from being impacted by other objects and reducing susceptibility to external contact, thus ensuring high safety. Furthermore, the unique shapes of the protrusions, grooves, and the first and second bases enhance brand recognition for manufacturers. In application, simply connect the terminals of the cables to be connected to the tails of the corresponding spring-loaded pins and conductive posts. Figure 1 As shown in the figure, only one cable a is shown.

[0040] The embodiments described herein are merely preferred embodiments of the invention and are not intended to limit the concept and scope of the invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the invention without departing from the design concept of the invention should fall within the protection scope of the invention. The technical content for which protection is sought in this invention has been fully described in the claims.
