Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a rotary connector. Background Art

[0002] Connectors can be used to electrically connect devices to lines, and can be used to transmit signals, currents, etc. When in use, signals or currents need to be transmitted stably, so the connection to the device needs to be stable and not easy to loosen. However, the connection between traditional connectors and devices cannot be self-locking, and operators still need to manually lock them, which requires operators to use both hands, which affects the operator's use. Summary of the invention

[0003] Based on this, the present invention aims to overcome the defects of the prior art and provide a self-locking rotary connector.

[0004] The technical solution is as follows:

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] like Figures 1 to 4As shown, an embodiment discloses a rotary connector, including a handle 100, an intermediate body 200 and a rotating body 300, wherein the rotating body 300 is sleeved outside the middle part of the intermediate body 200, and the intermediate body 200 includes a first part 210 and a second part 220 located outside the rotating body 300, one end of the handle 100 is connected to the first part 210, and an elastic member 400 is provided between the other end of the handle 100 and the front end of the rotating body 300, and the elastic member 400 is used to return the rotating body 300 to the initial position, and the second part 220 is provided to the rotating body 300. 20 and the rear end of the rotating body 300 are used to extend into the assembly hole 11 of the to-be-connected member 10, the second part 220 can slide along the axial direction of the assembly hole 11 and be fixed circumferentially, a first buckle 301 is provided on the rear end of the rotating body 300, and a second buckle 12 is provided on the inner wall of the assembly hole 11, the first buckle 301 and the second buckle 12 are correspondingly arranged in the axial direction of the assembly hole 11, when the first buckle 301 conflicts with the second buckle 12, the first buckle 301 is squeezed by the second buckle 12, so that the rotating body 300 rotates.

[0031] The above-mentioned rotary connector can extend the second part 220 of the intermediate body 200 and the rear end of the rotating body 300 into the assembly hole 11 of the member 10 to be connected by pushing the handle 100. The second part 220 can slide along the assembly hole 11 and be fixed circumferentially, so it will not rotate while sliding, and the handle 100 connected to the intermediate body 200 will not rotate. During the insertion process, the first buckle 301 approaches the second buckle 12 and contacts it, and the rotating body 300 rotates, so that the first buckle 301 can let the second buckle 12 pass. Since the handle 100 does not rotate, the elastic member 4 connected to the handle 100 and the rotating body 300 respectively 00 will undergo elastic deformation, and when the first buckle 301 moves to the side of the second buckle 12 away from the handle 100, the first buckle 301 and the second buckle 12 are no longer in contact, and the elastic member 400 will release the elastic potential energy to return the rotating body 300 to the initial position. At this time, the first buckle 301 and the second buckle 12 overlap in the axial direction of the assembly hole 11. If the handle 100 is pulled, the second buckle 12 will block the first buckle 301, so that the rotary connector cannot be pulled out of the assembly hole 11. Therefore, the above-mentioned rotary connector can be self-locking and can be locked by pushing the handle 100 with one hand, which is easy to operate.

[0032] Alternatively, if Figure 4 As shown, in the direction along the handle 100 approaching the to-be-connected member 10, the first buckle 301 has a first position and a second position in sequence. Figure 4 On the left side, the first buckle 301 is located at the first position. Figure 4 The middle part is where the first buckle 301 contacts the second buckle 12. Figure 4On the right side, the first buckle 302 is located at the second position. The first position and the second position are respectively located on both sides of the second buckle 12. At the first position, the first buckle 301 conflicts with the second buckle 12, and then the first buckle 301 can slide along the side of the second buckle 12 to rotate the rotating body 300. As the second part 220 continues to penetrate into the assembly hole 11, the first buckle 301 is no longer in contact with the second buckle 12, and the elastic member 400 drives the rotating body 300 to return. At this time, the first buckle 301 is located at the second position, and the second buckle 12 can block the first buckle 301, so as to achieve self-locking.

[0033] In one embodiment, if Figure 1 and Figure 4 As shown, the first buckle 301 is provided with a first inclined surface, and the second buckle 12 is provided with a second inclined surface arranged opposite to the first inclined surface. When the first buckle 301 is connected with the second buckle 12, the first inclined surface is connected with the opposite end of the second inclined surface. Through the mutual guidance of the first inclined surface and the second inclined surface, it can be ensured that the first buckle 301 is squeezed to one side by the second buckle 12 during the process of penetrating into the assembly hole 11, causing the rotating body 300 to rotate under the drive of the first buckle 301, and then the first buckle 301 exceeds the position of the second buckle 12 and rotates under the action of the elastic member 400 to achieve self-locking. In this process, the handle 100 does not need to be rotated, and it can be self-locked by pressing the handle 100 against the to-be-connected member 10. The operation is simple and can be operated with one hand, which is convenient for operators.

[0034] Optionally, the first buckle 301 and the second buckle 12 are both polygonal structures. At the first position, a tip of the first buckle 301 is arranged opposite to a tip of the second buckle 12. At the second position, a side of the first buckle 301 is arranged opposite to a side of the second buckle 12, so that the self-locking of the above rotary connector can be achieved. Specifically, the first buckle 301 and the second buckle 12 are both triangular structures.

[0035] In other embodiments, the first buckle 301 and the second buckle 12 may also be a semicircular structure. At the first position, the arc edge of the first buckle 301 is arranged opposite to the arc edge of the second buckle 12, and at the second position, the straight edge of the first buckle 301 is arranged opposite to the straight edge of the second buckle 12, which may also realize the self-locking function; or the first buckle 301 and the second buckle 12 may also be a semi-elliptical structure.

[0036] In one embodiment, if Figure 3 and Figure 5As shown, the rear end and the second part 220 are both in clearance fit with the assembly hole 11, the assembly hole 11 is provided with a slide groove 13, the second part 220 is provided with a protrusion 221 that is slidably matched with the slide groove 13, the first buckle 301 and the second buckle 12 are located between the outer wall of the rear end and the inner wall of the assembly hole 11, and the slide groove 13 and the second buckle 12 are arranged at intervals in the circumferential direction of the assembly hole 11. At this time, the inner wall of the assembly hole 11 will not interfere with the first buckle 301 extending into the assembly hole 11, the protrusion 221 can cooperate with the slide groove 13, so that the intermediate body 200 remains circumferentially fixed, and the first buckle 301 on the rear end can also enter the assembly hole 11 and contact with the second buckle 12, so as to realize the self-locking of the above-mentioned rotary connector.

[0037] In other embodiments, a limit groove is provided on the end face of the rear end, and a limit column is provided in the assembly hole 11, through which the limit column enters the limit groove to realize the circumferential fixation of the middle piece 200; or a yield hole is provided on the inner wall of the assembly hole 11, and a connected spring and a protrusion are provided in the yield hole, and the protrusion part extends out of the yield hole, and a recess is provided on the outer wall of the rear end, and the protrusion can be stuck in the recess, and the circumferential fixation of the middle piece 200 can also be realized.

[0038] In one embodiment, if Figure 2 As shown, a stopper 302 is protruding outward from the middle of the rotating body 300 , and the stopper 302 is used to abut against the member to be connected 10 . When the stopper 302 abuts against the member to be connected 10 , the first buckle 301 is arranged on the side of the second buckle 12 away from the stopper 302 . When the handle 100 moves in the direction approaching the part to be connected 10, the first buckle 301 contacts before the second buckle 12. Due to the squeezing of the second buckle 12 on the first buckle 301, the first buckle 301 drives the rotating body 300 to rotate. When the first buckle 301 continues to move until it is no longer in contact with the second buckle 12, the rotating body 300 is reset under the action of the elastic member 400, so that the second buckle 12 can block the first buckle 301 to achieve self-locking, and the baffle can limit the distance that the first buckle 301 extends into the assembly hole 11, so that the first buckle 301 can extend through the second buckle 12 to achieve self-locking, and at the same time will not excessively extend into the assembly hole 11 to affect the assembly effect. Therefore, the blocking portion 302 can play a role in auxiliary operation, so that the operator only needs to press the handle 100 toward the part to be connected 10 until the handle 100 can no longer move forward, indicating that the self-locking is successful, and the operation is simple and effective.

[0039] In one embodiment, if Figure 6 and Figure 7As shown, a guide column 303 is provided on the inner wall of the rotating body 300, and a guide groove 201 is provided on the intermediate body 200 for sliding cooperation with the guide column 303. The guide groove 201 includes a first groove section 202 and a second groove section 203 that are connected. The first groove section 202 is arranged along the axial direction of the intermediate body 200, and the first groove section 202 extends to the first part 210. The second groove section 203 is arranged along the circumferential direction of the intermediate body 200. When the first buckle 301 conflicts with the second buckle 12, the guide column 303 slides along the second groove section 203. Since the positions of the slide groove 13 and the second buckle 12 in the assembly hole 11 are fixed, and the slide groove 13 needs to slide with the protrusion 221, and the second buckle 12 needs to contact the first buckle 301, it is necessary to ensure the accuracy of the relative position of the first buckle 301 and the protrusion 221 during the assembly process to ensure that the corresponding components can be aligned after assembly. Therefore, the first groove section 202 and the guide column 303 are set to slide together to ensure the accurate assembly of the intermediate body 200 and the rotating body 300. During the assembly process, the intermediate body 200 needs to be circumferentially fixed while the rotating body 300 can rotate. Therefore, the second groove section 203 connected to the first groove section 202 is set. The second groove section 203 can be used as a clearance space for the guide column 303 to move when the rotating body 300 rotates. Therefore, the above structure can facilitate assembly and improve assembly accuracy without affecting the self-locking effect.

[0040] In other embodiments, the guide pillar 303 may also be disposed on the outer wall of the intermediate body 200 , and the guide groove 201 may also be disposed on the inner wall of the rotating body 300 , and the above-mentioned effect may also be achieved.

[0041] In one embodiment, if Figure 6 and Figure 8 As shown, a guide portion 101 is provided inside the handle 100, and the guide portion 101 is slidably matched with the first groove section 202. Through the slidable match between the guide portion 101 of the handle 100 and the first groove section 202, the handle 100 and the middle piece 200 can be linked, so when the rotating body 300 rotates, the handle 100 and the middle piece 200 are both kept circumferentially fixed, and the handle 100 only needs to be pressed against the to-be-connected member 10 to achieve self-locking, thereby simplifying the connection operation.

[0042] In one embodiment, if Figure 1 and Figure 3As shown, the rotating body 300 includes a first split part 310 and a second split part 320 that are connected to each other, the elastic part 400 is arranged on the first split part 310, the outer edge of the first split part 310 is bent toward the second split part 320 to form a bayonet 311, one end of the second split part 320 matches the bayonet 311 and is snapped with the first split part 310, the second split part 320 and the first split part 310 form a receiving cavity 304, and the first buckle 301 is arranged on the other end of the second split part 320. Through the arrangement of the first split part 310 and the second split part 320, chips, sensors, etc. can be placed in the receiving cavity 304, so as to integrate multiple functions in the above-mentioned rotary connector and expand the use of the above-mentioned rotary connector.

[0043] Optionally, a positioning groove is provided in the bayonet 311 , and a positioning piece engaged with the positioning groove is provided on the outer edge of the second split piece 320 , so that the first split piece 310 and the second split piece 320 can be docked without relative rotation.

[0044] In one embodiment, if Figure 7 and Figure 8 As shown, the elastic member 400 is a torsion spring, which is sleeved outside the intermediate body 200, a first limiting portion 305 is provided on the rotating body 300, and a second limiting portion 102 is provided on the inner wall of the handle 100, and the first limiting portion 305 and the second limiting portion 102 are respectively used to clamp the two ends of the elastic member 400. Through the action of the torsion spring, the first buckle 301 on the rotating body 300 can rotate when being squeezed by the second buckle 12, and at the same time, when the first buckle 301 extends through the second buckle 12, the rotating body 300 returns to its original position to achieve self-locking. The principle is simple and effective, and the torsion spring has a low cost, which can reduce the overall cost of the above-mentioned rotary connector.

[0045] In other embodiments, the elastic member 400 may also be a spring sheet, the two ends of which are respectively connected to the rotating body 300 and the handle 100. When the rotating body 300 rotates, the spring sheet bends. When the rotating body 300 is not subjected to force, the spring sheet returns to its original position, causing the rotating body 300 to rotate, and self-locking may also be achieved.

[0046] Alternatively, if Figure 8 As shown, the second limiting portion 102 is a limiting hole provided on the inner wall of the handle 100, and one end of the torsion spring can be inserted into the limiting hole to limit the one end of the torsion spring.

[0047] Alternatively, if Figure 7 As shown, a plurality of bosses 312 are provided on the side of the rotating body 300 away from the part to be connected 10. The bosses 312 are arranged at intervals along the circumference of the intermediate part 200. A first limiting portion 305 is formed between two adjacent bosses 312. A torsion spring is arranged between the intermediate part 200 and the boss 312. The other end of the torsion spring can be extended between two adjacent bosses 312 to limit the other end of the torsion spring.

[0048] In one embodiment, if Figure 1 and Figure 3 As shown, the rotary connector further includes a contact pin 510 and an abutment member 520. A mounting hole is provided in the intermediate body 200, and an annular step 204 is provided in the mounting hole. The contact pin 510 includes a needle head and a main body, and the needle head passes through the annular step 204. The abutment member 520 is threadedly matched with the mounting hole, and the abutment member 520 and the annular step 204 are used to match and clamp the main body. The abutment member 520 can be used to press the contact pin 510, and the needle head of the contact pin 510 is used to electrically connect with the internal circuit of the component 10 to be connected.

[0049] In one embodiment, if Figure 1 and Figure 3 As shown, the rotary connector further includes a fastener 600, which is sleeved outside the abutment 520. The fastener 600 includes a stopper 610 and a threaded portion 620. The threaded portion 620 extends between the handle 100 and the first portion 210 and is threadedly matched with the first portion 210. The stopper 610 is used to abut the handle 100. A wire hole is provided in the abutment 520. A plurality of clamping portions 521 are provided at intervals along the circumferential direction at one end of the abutment 520 close to the fastener 600. The inner hole diameter of the fastener 600 gradually decreases in the direction away from the contact pin 510. At this time, the relative position of the intermediate body 200 and the handle 100 can be limited by the fastener 600, and it can be easily disassembled and assembled to replace the components of the rotary connector to facilitate the realization of different functions or maintenance. The clamping portion 521 can clamp the wire electrically connected to the contact pin 510 to prevent problems during its installation and use.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
