Description

Technical Field

[0001] This utility model relates to the field of electrical connector structure technology, specifically to a rotary switch type connector structure that performs terminal insertion and removal actions by relative rotation of male and female ends. Background Technology

[0002] Currently, slot connector housings are composed of an insulating body made of plastic and terminals made of metal. The terminals are embedded in slots within the insulating body, and the insertion slots formed between the terminals are electrically connected to external connectors.

[0003] Traditional pluggable connectors connect by making contact between male and female terminals during each plugging and unplugging process to conduct or disconnect electrical signals. During contact, sliding friction occurs between the two, and after long-term use, the contacts are prone to wear and oxidation, resulting in increased contact resistance. For example, USB and power plugs will experience poor contact after repeated plugging and unplugging. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotary switch connector structure with compact insertion and good electrical connectivity.

[0005] The present invention adopts the following technical solution: A rotary switch connector structure mainly consists of a male head body, a female head body, male terminals, and female terminals. The male and female terminals are respectively engaged in the male and female slots of the male head body. The male and female head bodies rotate relative to each other through the pin structure at their ends, causing the male and female terminals engaged in the male and female slots of the male head body to make contact or disconnect. Locking structures on the male and female head bodies are used to lock or unlock them, thereby realizing the electrical connection and disconnection of the male and female terminals. The male connector body is a box structure, with shafts protruding outward on both sides of one end, and a stop part on the male connector body above the shaft. At the bottom of the other end of the male connector body, there is a downward-facing male connector groove for locking the male connector terminal. Locking handles are fixed to the lower part of both sides of the male connector body near the male connector groove. The top of the female connector body corresponds to the bottom of the male connector body. At the position of the male connector groove that locks the male connector terminal at the bottom of the corresponding housing, there is an upward-facing female connector groove that locks the female connector terminal. The female connector body has a shaft on one side of the corresponding housing and support arms on the other side. The support arms have shaft holes that rotate relative to the shaft. The female connector body has locking blocks fixed at the position of the locking handle on the lower part of the corresponding housing. An upward-facing stop block is fixed at the other end of the female connector body away from the female connector groove. Elastic locking blocks are symmetrically arranged at the bottom of the female connector body. The female terminal is a bow-shaped spring clip. After it is locked in the groove of the female head, the curved surface formed by the bow still protrudes on the upper surface of the female head body. The locking structures are a latching handle on the male head body and a latching fixing block on the female head body. The latching handle has a T-shaped structure, with one bottom end of the T-shape fixed to the male head body and the other bottom end of the T-shape forming a hook shape facing the male head body. The latching fixing block is fixed on the female head body below the hook shape corresponding to the male head body and is a strip shape with an outward slant. The stop block of the female head body is set in the clearance groove of the female head body; The top of the support arm is arc-shaped; The gaps between the edges of the stop block on both sides and the support arms on the main body of the female head form a space that can accommodate the stop portion; The arc segments of the support arms of the male head body and the female head body are corresponding arc-shaped grooves; The elastic locking block is an outward-expanding hook.

[0006] The features of this utility model are: 1. Because the connection is fixed by a fixed rotating shaft and a snap-fit ​​structure, the pressure at the contact point is continuously maintained by the mechanical structure, and there will be no "loose connection" or disconnection due to equipment vibration or accidental pulling, thus increasing the stability of the connection. 2. Compared to traditional plug-in connections that require precise alignment of the interface's "convex and concave structure" (such as USB and power plugs), making operation in dark / confined spaces difficult, this structure can be locked simply by rotating and pressing, offering a higher tolerance for errors. 3. This connector has an optimized docking method in terms of structure, which greatly increases its service life. Attached Figure Description

[0010] See attached Figures 1-6 A rotary switch connector structure mainly consists of a male connector body 1, a female connector body 2, a male connector terminal 3, and a female connector terminal 4. The male connector terminal 3 and the female connector terminal 4 are respectively engaged in the male connector slot 14 and the female connector slot 24 of the male connector body 1. The male connector body 1 and the female connector body 2 rotate relative to each other through the pin structure at their ends, so that the male connector terminal 3 and the female connector terminal 4 engaged in the male connector slot 14 and the female connector slot 24 of the male connector body 1 respectively make contact or disconnect. The locking structure on the male connector body 1 and the female connector body 2 locks or opens, thereby realizing the electrical connection and disconnection of the male connector terminal 3 and the female connector terminal 4. The male head body 1 is a box structure, with shafts 11 protruding outward on both sides of one end, and a stop part 12 is provided on the male head body 1 above the shafts 11. A male head groove 14 for locking the male head terminal 3 is provided at the bottom of the other end of the male head body 1. Locking handles 13 are fixed on the lower part of both sides of the upper end of the male head body 1 near the male head groove 14. The top of the female head body 2 corresponds to the bottom of the male head body 1. At the position of the male head groove 1 that locks the male head terminal 3 at the bottom of the corresponding housing, there is an upward-facing female head groove 24 that locks the female head terminal 4. The female head body 2 has a shaft 11 on both sides of one end of the corresponding housing and a support arm 21 on both sides of the other end. The support arm 21 has a shaft hole 211 that rotates relative to the shaft 11. The female head body 2 has a locking block 22 fixed at the position of the locking handle 13 on the lower part of both sides of the corresponding housing. An upward-facing stop block 25 is fixed at the other end of the female head body 2 away from the female head groove 24. Elastic locking blocks 23 are symmetrically arranged at the bottom of the female head body 2. The female terminal 4 is a bow-shaped spring piece. After it is locked in the female groove 24, the curved surface formed by the bow still protrudes on the upper surface of the female body 2. The locking structures are a latching handle 13 on the male head body 1 and a latching fixing block 22 on the female head body 2. The latching handle 13 has a T-shaped structure, with one bottom end of the T-shape fixed to the male head body 1 and the other bottom end of the T-shape forming a hook shape facing the male head body 1. The latching fixing block 22 is fixed on the female head body 2 below the hook shape of the male head body 1 and is a strip shape with an outward sloping surface. The stop block 25 of the female head body 2 is provided in the clearance groove 26 of the female head body 2; The top of the support arm 21 is arc-shaped; The gap between the edges of the stop block 25 on both sides and the support arm 21 on the main body 2 of the female head forms a space that can accommodate the stop part 12; The arc segments of the support arms 21 of the male head body 1 and the female head body 2 are corresponding arc-shaped grooves 15.

[0011] The elastic locking block 23 is an outward-expanding hook.

[0012] When applying this utility model, the male terminal 3 is snapped into the male groove 14 of the male body 1, and the curved surface of the female terminal 4 formed by the bow is snapped into the female groove 24 of the female body 2. The shaft 11 on the male body 1 and the shaft hole 211 on the support arm 21 of the female body 2 are assembled into a whole that can rotate relative to each other. Then, the elastic buckle 23 at the bottom of the female body 2 is snapped into the fixing groove set in the PCB board. Since the elastic buckle 23 is an outward-expanding hook, after being squeezed into the fixing groove of the PCB board, the outward-expanding hook hooks the bottom of the PCB board, fixing the male body 1 and the female body 2 at the designated position on the PCB board. When connection is required, the male connector body 1 is pulled down. Through the rotation between the shaft 11 on the male connector body 1 and the shaft hole 211 on the support arm 21 of the female connector body 2, the male connector terminal 3 locked in the male connector groove 14 moves down, so that the female connector terminal 4 protruding on the upper surface of the female connector body 2 and the male connector terminal 3 make a pressure contact, and the circuit is connected. At the same time, the locking handles 13 on both sides of the male connector body 1 move synchronously. The hook-shaped end of the T-shaped locking handle 13 slides down and passes through the strip-shaped locking fixing block 22 with an outward bevel, hooking onto the bottom surface of the locking fixing block 22 fixed to the female connector body 2. When disconnection is required, the male head body 1 is pulled upward by the locking handle 13 on the male head body 1. The external force causes the locking handle 13 to elastically deform. The hook-shaped end of the T-shaped locking handle 13 deforms and moves outward, moving out of the bottom surface of the locking block 22. Through the rotation between the shaft 11 on the male head body 1 and the shaft hole 211 on the support arm 21 of the female head body 2, the male head body 1 rotates upward around the shaft hole 211 on the support arm 21 of the female head body 2. The stop part 12 on the male head body 1 rotates downward until the space between the edges on both sides of the stop block 25 and the support arm 21 on the female head body 2 can accommodate the stop part 12, thus blocking it and achieving the locking of the male head body 1. Since the top of the support arm 21 is arc-shaped, and the arc segments of the support arms 21 of the male head body 1 and the female head body 2 are corresponding arc-shaped grooves 15, mutual interference is avoided when the male head body 1 and the female head body 2 rotate relative to each other, thus reducing the overall size of this utility model. The stop block 25 of the female head body 2 is set in the clearance groove 26 of the female head body 2, which allows the male head body 1 and the female head body 2 to rotate relative to each other. The clearance space between the male head body 1 and the female head body 2 is artificially designed, which further reduces the overall size of this utility model.

[0013] Of course, the above detailed description of the present utility model in conjunction with the embodiments is only for illustrating the technical concept and features of the present utility model. Its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it. Therefore, all equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
