Detailed Implementation

[0039] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0040] This utility model provides a small-pitch spring-type magnetic connector. By setting the terminal 2 as a sheet-like integrated structure, the spacing between the terminals 2 can be shortened, thereby reducing the spacing and shortening the overall size of the connector, which can meet the connection requirements of small pitch and small space. Specifically, a plurality of mounting cavities 11 arranged side by side are formed on the base 1. The terminals 2 are sheet-like structures and are respectively assembled in the mounting cavities 11. The terminals 2 are fixedly installed in the mounting cavities 11 by the connecting parts 23. The abutting parts 21 extend elastically out of the mounting cavities 11 under the elastic thrust of the elastic parts 22. The magnetic parts 3 are fitted on the base 1. In this embodiment, the connector provided is a male plug. When it is mated with the female plug, the magnetic parts on the two connectors attract each other, thereby stably connecting the two connectors. At this time, the abutting parts 21 abut against the connecting parts on the female plug and compress the elastic parts 22 to make it elastically deformed. Under the action of elastic force, the abutting parts 21 and the connecting parts are firmly abutted. Since the terminals 2 in this utility model are sheet-like and integral structures, their thickness is small, and a small gap can be set between the two terminals 2. At the same time, the overall size of the connector can be reduced, which can meet the needs of small-size places.

[0041] Specifically, in the embodiments of this utility model, such as Figures 1-5As shown, a small-pitch spring-loaded magnetic connector includes a base 12, terminals 2, and a magnetic component 3. The base 1 has several mounting cavities 11 arranged side-by-side along a predetermined direction. Each terminal 2 has multiple terminals corresponding to and respectively assembled within the mounting cavities 11, and each terminal 2 is plate-shaped. From top to bottom, each terminal 2 has an abutment portion 21, an elastic portion 22, and a connecting portion 23. The abutment portion 21 extends out of the mounting cavity 11 to abut against the female connector. The elastic portion 22 provides elastic support to the abutment portion 21. The connecting portion 23 is fixedly mounted in the mounting cavity 11, with one end of the connecting portion 23 away from the elastic portion 22 extending out along the mounting cavity 11. The magnetic component 3 is fixedly disposed on the outside of the base 1.

[0042] In this embodiment, the terminals 2 are configured as sheet-like structures and are fixedly installed in the mounting cavity 11, so that the abutting part 21 extends elastically out of the mounting cavity 11 under the elastic force of the elastic part 22, thereby enabling mutual abutment of the female plug. After configuring the terminals 2 as sheet-like structures, the thickness of the terminals 2 can be reduced, thereby shortening the gap between two adjacent terminals 2. At the same time, under the mutual attraction of the magnetic parts 3, the connection between the two mating connectors can be made more reliable. The technical solution provided by this utility model embodiment can reduce the gap between the terminals 2 and further reduce the overall size of the connector, which can adapt to the use requirements of smaller spaces.

[0043] In this embodiment, the mounting cavity 11 is provided with an outlet end 111, a receiving portion 112, and a mounting end 113 sequentially from top to bottom. The outlet end 111 is configured with a constricted opening structure, and the abutment portion 21 extends out of the mounting cavity 11 along the outlet end 111. The receiving portion 112 is used to accommodate the elastic portion 22, and the width of the receiving portion 112 is greater than the width of the elastic portion 22. The mounting end 113 is used to accommodate the connecting portion 23 and snaps the connecting portion 23 inside. The outlet end 111 with the constricted opening structure limits the abutment portion 21, preventing it from extending too far out of the mounting cavity 11, or even extending into the mounting cavity 11. During the docking process with the connector, the abutment portion 21 receives pressure and retracts into the mounting cavity 11, thereby compressing the elastic portion 22 and causing the elastic portion 22 to undergo elastic deformation. At this time, the receiving portion 112 has a width greater than the elastic portion 22, thereby providing sufficient deformation space and preventing incomplete deformation of the elastic portion 22 due to insufficient space, which would affect the retraction of the abutment.

[0044] In this embodiment, to facilitate the installation of terminal 2, the housing 112 is provided with a first segment 1121 and a second segment 1122 from top to bottom. The first segment 1121 has a rectangular vertical cross-section. The width of the second segment 1122 gradually increases from the first segment 1121 to the mounting end 113, making its vertical cross-section trapezoidal. That is, the second segment 1122 is designed as a flared shape, so that the terminal 2 can be assembled conveniently and quickly when assembled along the mounting end 113.

[0045] In this embodiment, to prevent the abutment portion 21 from falling out at the port along the mounting cavity 11, that is, to prevent the abutment portion 21 from protruding too much at the outlet end 111, a first limiting portion 211 extending in the lateral direction is formed on the end of the abutment portion 21 near the elastic portion 22, and the elastic portion 22 is connected to the limiting portion. Figure 3 , 5 As shown, the abutting part 21 is mutually limited by the first limiting part 211 and the outlet end 111, so that the terminal 2 will not fall out of the outlet end 111 of the mounting cavity 11, and also avoid the abutting part 21 extending too far out of the outlet end 111.

[0046] In this embodiment, the connecting portion 23 includes a main body 231 and a pin 232 formed on the end of the main body 231 away from the elastic portion 22. The elastic portion 22 is connected to the main body 231, and a second limiting portion 233 is formed on the side of the main body 231 extending in the lateral direction, such that the width of the main body 231 is larger than the width of the elastic portion 22. By setting the main body 231, the signal transmission capability is ensured. At the same time, the second limiting portion 233 can limit the installation position of the main body 231, preventing it from protruding too much from the mounting cavity 11.

[0047] In this embodiment, as Figure 5 As shown, a specific example of the shape of the elastic part 22 is given. The two ends of the elastic part 22 are connected to the abutment part 21 and the connecting part 23, respectively, and it extends in a bent manner between the abutment part 21 and the connecting part 23. Through the bent structure, the bent structure can undergo axial elastic deformation along the axial direction when the abutment part 21 is subjected to pressure, thereby realizing the elastic support capability for the abutment part 21.

[0048] Specifically, the elastic part 22 includes a first bending part 221, a bend part 222, and a second bending part 223. One end of the first bending part 221 is tangentially connected to the abutment part 21. The bend part 222 includes a plurality of elastic strips 2221 arranged laterally and side by side. An arc-shaped connecting arc 2222 is provided between the ends of two elastic strips 2221. The two ends of the connecting arc 2222 are tangentially connected to two adjacent elastic strips 2221 respectively. One end of the second bending part 223 is tangentially connected to an elastic strip 2221 of the bend part 222 near the connecting part 23, and the other end is integrally formed with the connecting part 23. When the contact portion 21 is subjected to pressure, the first curved portion 221, the second curved portion 223, and the connecting arc 2222 used to connect adjacent elastic bands 2221 undergo elastic deformation. Specifically, their radii gradually decrease, thereby gradually reducing the distance between the elastic bands 2221, and the elastic bands 2221 gradually tilt, thereby reducing the length of the elastic portion 22 and generating elastic deformation during compression.

[0049] In order to install magnetic component 3, such as Figure 4 As shown, the base 1 includes a base 12 and a protrusion 13 formed on the base 12 and protruding upward. The outlet of the mounting cavity 11 for the abutment portion 21 to extend out is located on the end face of the protrusion 13. The magnetic component 3 has a central hole 31 that matches the protrusion 13. The magnetic component 3 is fitted onto the protrusion 13 through the central hole 31 and is fixedly connected to the protrusion 13. In this embodiment, after the magnetic component 3 is sleeved on the protrusion 13, it is glued to achieve a fixed connection with the base 12. In other embodiments, it can also be fixedly assembled by snap-fit ​​or other methods.
