[0004] As in the above-mentioned utility model, although the harness can be fixed by the clamp to prevent the harness from being easily loosened, when replacing the harness, the clamp needs to be disassembled first, which makes the replacement of the harness more cumbersome, takes more time, and reduces the replacement efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a circular electrical connector to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A circular electrical connector includes a first connection head and a second connection head. A fixed platform is fixedly connected inside the first connection head. Four clamping pieces are fixedly connected to one end of the fixed platform. An adjusting screw sleeve is threadedly connected inside the first connection head. One end of the adjusting screw sleeve abuts against the tops of the four clamping pieces. Four sliding grooves are opened inside the first connection head. Slide bars are slidably connected inside the four sliding grooves. One ends of the four slide bars all abut against one end of the adjusting screw sleeve. The other ends of the four slide bars are fixedly connected to a pushing ring. One end of the pushing ring is fixedly connected to an elastic sealing sleeve. The other end of the elastic sealing sleeve is fixedly connected to the inside of the first connection head. The internal structure of the first connection head is the same as that of the second connection head.

[0007] As a further preference of this technical solution, a connection seat is fixedly connected to one end of the first connection head. A separating ring is fixedly connected inside the connection seat at one end of the first connection head. A docking screw sleeve is rotatably connected to the outer surface of the second connection head near one end. The inner surface of the docking screw sleeve is threadedly connected to the outer surface of the connection seat. A sealing ring is fixedly connected to one end of the second connection head.

[0011] The utility model provides a circular electrical connector, which has the following beneficial effects:

[0012] (1) By rotating the adjusting sleeve in the utility model, the adjusting sleeve enters into the first connecting head or the second connecting head. During the entering process, the adjusting sleeve gradually contacts the top of the clamping piece, and in the subsequent moving process, the four clamping pieces are extruded towards the center, so that the inner sides of the four clamping pieces extrude the surface of the wire harness. At the same time, the movement of the adjusting sleeve in the first connecting head pushes the four sliding rods to move in the sliding grooves. During the movement of the sliding rods, the pushing ring is driven to extrude the elastic sealing sleeve. During the extrusion process, the elastic sealing sleeve contracts inward due to the effect of the guiding groove, effectively avoiding the phenomenon of separation between wire harnesses during the pulling process of the wire harness and improving the sealing effect. The structure is simple, the connection is firm, and the disassembly is convenient.

[0013] (2) When the first connecting head and the second connecting head are connected by rotating the docking nut in the utility model, the sealing ring enters between the connecting seat and the separating ring, and applies pressure to the sealing gasket, causing the sealing gasket to deform and apply a reaction force to the sealing ring, sealing the connection position between the first connecting head and the second connecting head, achieving the sealing protection of the connection, effectively avoiding the entry of water, and improving the safety factor.

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The present invention provides a technical solution: As Figures 1-3 shown, in this embodiment, a circular electrical connector includes a first connector 1 and a second connector 2. A fixed platform 3 is fixedly connected inside the first connector 1. Four clamping pieces 4 are fixedly connected to one end of the fixed platform 3. An adjusting sleeve 5 is threadedly connected inside the first connector 1. One end of the adjusting sleeve 5 abuts against the tops of the four clamping pieces 4. Four slide grooves 6 are opened inside the first connector 1. Slide bars 7 are slidably connected inside the four slide grooves 6. One ends of the four slide bars 7 abut against one end of the adjusting sleeve 5. The other ends of the four slide bars 7 are fixedly connected to a pushing ring 8. One end of the pushing ring 8 is fixedly connected to an elastic sealing sleeve 9. The other end of the elastic sealing sleeve 9 is fixedly connected to the inside of the first connector 1. The internal structure of the first connector 1 is the same as the internal structure of the second connector 2. Among them, by setting the clamping pieces 4, the outer surface of the wire harness can be fixed under the drive of the adjusting sleeve 5. By setting the elastic sealing sleeve 9, the wire harness can be sealed under the action of the pushing ring 8 to prevent rainwater and the like from entering the connection position.

[0020] As Figure 2 and Figure 3 shown, a connection seat 17 is fixedly connected to one end of the first connector 1. A partition ring 11 is fixedly connected inside the connection seat 17 at one end of the first connector 1. A docking sleeve 10 is rotatably connected to the outer surface of the second connector 2 near one end. The inner surface of the docking sleeve 10 is threadedly connected to the outer surface of the connection seat 17. A sealing ring 12 is fixedly connected to one end of the second connector 2. The sealing ring 12 is inserted into the gap formed between the connection seat 17 and the partition ring 11. By setting the docking sleeve 10 and the connection seat 17, the first connector 1 and the second connector 2 are connected, and the connection position of the wire harness is sealed. By setting the sealing ring 12, the cooperation with the partition ring 11 can seal the connection position and improve the waterproof effect.

[0021] As Figure 2 shown, a sealing gasket 13 is placed between the connection seat 17 and the partition ring 11. One end of the sealing gasket 13 is in close contact with one end of the sealing ring 12, which can perform secondary sealing and further improve the sealing effect.

[0022] As Figure 1 and Figure 2 shown, a sealing sieve 15 is inserted inside an adjusting sleeve 5. The outer surface of the sealing sieve 15 is in interference fit with the inside of the adjusting sleeve 5, which can seal between the wire harness and the adjusting sleeve 5 for preliminary waterproofing. After the wire harness is fixed, it is inserted into the adjusting sleeve 5 for sealing.

[0023] As Figure 2 and Figure 3 shown, a guiding groove 16 is provided at the middle position on the outer surface of an elastic sealing sleeve 9, and a friction pattern 14 is provided on the outer surface of a docking sleeve 10. By providing the guiding groove 16, the deformation direction of the elastic sealing sleeve 9 can be guided. By providing the friction pattern 14, it is convenient to rotate.

[0024] The present utility model provides a circular electrical connector, and the specific working principle is as follows:

[0025] The user inserts two wire harnesses to be connected into the inside of a first connector head 1 and a second connector head 2 respectively through the adjusting sleeve 5, passes through and connects from the two wire outlet holes, and then rotates the docking sleeve 10 to connect the docking sleeve 10 with a connecting seat 17, so that the first connector head 1 and the second connector head 2 are docked. During the docking process, a sealing ring 12 enters between the connecting seat 17 and a separating ring 11 and applies pressure to a sealing gasket 13, causing the sealing gasket 13 to deform and apply a reaction force to the sealing ring 12 to seal the connection position between the first connector head 1 and the second connector head 2. Rotate the adjusting sleeve 5 so that the adjusting sleeve 5 enters the inside of the first connector head 1 or the second connector head 2. During the entering process, the adjusting sleeve 5 gradually contacts the top ends of four clamping pieces 4, and squeezes the four clamping pieces 4 towards the center during the subsequent movement, so that the inner sides of the four clamping pieces 4 squeeze and fix the surface of the wire harness. At the same time, the movement of the adjusting sleeve 5 inside the first connector head 1 pushes four sliding rods 7 to move in sliding grooves 6. During the movement of the sliding rods 7, a pushing ring 8 is driven to squeeze the elastic sealing sleeve 9. During the squeezing process, the elastic sealing sleeve 9 contracts inward due to the effect of the guiding groove 16 to seal the wire harness.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
