[0046] Example

[0047] like Figure 1-7 As shown, the protective sleeve based on the cable connector proposed in the present application includes a cable, wherein the cable includes a first cable 101 and a second cable 102, and the connecting ends of the first cable 101 and the second cable 102 are respectively fixedly sleeved with a first inner sleeve 201 and a second inner sleeve 202, which play a role of tightening the ends of the first cable 101 and the second cable 102.

[0048] It also includes a connecting sleeve 9 and a connector 11 connected to the free ends of the first inner sleeve 201 and the second inner sleeve 202, respectively. The connecting end of the first cable 101 is provided with a second contact 14 extending into the connecting sleeve 9, and the connecting end of the second cable 102 is provided with a first contact 13 protruding from the connector 11, wherein the threaded portion of the connector 11 protrudes from the inner edge circle of the connector 11, the inner circle of the connecting sleeve 9 is provided with an internal thread, and the threaded portion of the connector 11 is provided with an external thread. When the connector 11 is completely screwed into the connecting sleeve 9, the first contact 13 and the second contact 14 are in tight contact, so that a complete circuit is formed after the first cable 101 and the second cable 102 are energized.

[0049] Among them, a sealing member 10 is commonly provided on the connecting sleeve 9 and the connecting head 11, and the sealing member 10 includes an annular groove 1001 opened at one end of the connecting sleeve 9, and a sealing gasket 1002 is embedded in the inner wall of the annular groove 1001. The inner edge ring of the connecting head 11 is connected with a contact ring 1003. After the connecting sleeve 9 and the connecting head 11 are connected, the contact ring 1003 contacts the sealing gasket 1002, so that the connecting end of the connecting sleeve 9 and the connecting head 11 has a sealing and waterproof effect, and is safer for outdoor use.

[0050] The side wall of the first inner sleeve 201 is slidably sleeved with a sleeve 3, the side wall of the mouth end of the sleeve 3 is fixedly sleeved with a protective sleeve 6, the side wall of the connector 11 is fixedly sleeved with a positioning sleeve 17, and the protective sleeve 6 is sleeved on the outer ring of the positioning sleeve 17. It should be noted that the outer ring of the end of the first inner sleeve 201 away from the connecting sleeve 9 is fixedly sleeved with an anti-slip ring 12, and the anti-slip ring 12 limits the axial position of the sleeve 3 to prevent the sleeve 3 from being separated from the first inner sleeve 201 before disassembly or connection.

[0051] Among them, the end of the protective sleeve 6 close to the connecting sleeve 9 is fixedly connected with a waterproof ring 7, and the inner ring of the waterproof ring 7 and the inner ring of the sliding sleeve 3 close to the connecting sleeve 9 are both connected with a sealing ring 18, and the waterproof ring 7 and the sealing ring 18 are both made of elastic silicone material. When the protective sleeve 6 is sleeved on the side wall of the positioning sleeve 17, the sealing ring 18 of the inner ring of the sliding sleeve 3 is in close contact with the outer wall of the connecting sleeve 9, and the sealing ring 18 of the inner ring of the waterproof ring 7 is in close contact with the side wall of the positioning sleeve 17, which can preliminarily block external rainwater. With the cooperation of the sealing member 10, it plays a good waterproof role.

[0052] Among them, the inner circle of the protective sleeve 6 is connected to a pair of second deflection positioning blocks 15, and the outer wall of the positioning sleeve 17 is provided with a pair of second deflection grooves 16 respectively matching the two second deflection positioning blocks 15. The end of the connecting sleeve 9 close to the sliding sleeve 3 is provided with a return auxiliary component 8 for reverse driving the sliding sleeve 3 and thus reverse positioning the protective sleeve 6, so that the protective sleeve 6 can be automatically positioned after being sleeved on the outside of the positioning sleeve 17, which reduces the difficulty of workers' construction operations and the positioning structure is stable. Among them, the second deflection groove 16 includes a second straight groove portion 161 opened on the outer wall of the positioning sleeve 17 and axially parallel to the positioning sleeve 17, one end of the second straight groove portion 161 is provided with a second arc groove portion 162 located in the circumferential direction of the outer wall of the positioning sleeve 17, and the second arc groove portion 162 is provided with a second deflection groove portion 163 parallel to the second straight groove portion 161 at one end away from the second straight groove portion 161. The second deflection positioning block 15 is positioned in the second deflection groove portion 163 under the action of the return auxiliary component 8, so as to position the positioning sleeve 17 axially and circumferentially.

[0053] Specifically, a pair of first deflection positioning blocks 4 are fixedly connected to the inner ring of the sliding end of the sliding sleeve 3, and a pair of first deflection grooves 5 are provided on the outer wall of the first inner sleeve 201, and two first deflection positioning blocks 4 slide in the two first deflection grooves 5 respectively. The first deflection groove 5 includes a first straight groove portion 51 provided on the outer wall of the first inner sleeve 201 and arranged horizontally with the axial direction of the first inner sleeve 201, and a first arc groove portion 52 located in the circumferential direction of the outer wall of the first inner sleeve 201 is provided at the end of the first straight groove portion 51, and a first deflection groove portion 53 parallel to the first straight groove portion 51 is provided at one end of the first arc groove portion 52 away from the first straight groove portion 51, and the first deflection positioning block 4 is positioned in the first deflection groove portion 53 under the action of the rebound force of the return auxiliary component 8. During operation, the two first deflection positioning blocks 4 slide from one end of the two first straight groove portions 51 to the other end of the two first straight groove portions 51, and then the sliding sleeve 3 is rotated to make the two first deflection positioning blocks 4 slide in the two first arc groove portions 52, and slide to the other end of the two first arc groove portions 52, and then the sliding sleeve 3 is released, and under the elastic force of the return auxiliary component 8, the two first deflection positioning blocks 4 are respectively abutted in the two first deflection groove portions 53, thereby completing the positioning of the sliding sleeve 3 and the protective sleeve 6.

[0054] Specifically, the return auxiliary member 8 includes a plurality of grooves 801 provided at one end of the connecting sleeve 9, the inner walls of the plurality of grooves 801 are fixedly connected with return springs 802, and the outer ends of the plurality of return springs 802 are commonly fixedly connected with a rebound ring 804. The rebound ring 804 is rotatably connected with a protective ring 805 at one end away from the return spring 802, and an annular groove is provided at the end surface of the protective ring 805, and a sliding ring sliding in the annular groove is connected to the end surface of the protective ring 805. The purpose of providing the protective ring 805 is to avoid friction resistance between the sliding sleeve 3 and the rebound ring 804 when the sliding sleeve 3 is rotated, so that the rebound ring 804 deviates from the connecting sleeve 9 and the return spring 802 deviates in direction, affecting the rebound effect. The outer end of the return spring 802 is sleeved with a guide cylinder 803, and the guide cylinder 803 is fixedly connected to the rebound ring 804. The guide cylinder 803 is inserted into the groove 801 and is slidably connected to the groove 801. A sliding limiter cooperating with the guide cylinder 803 is arranged in the groove 801, and a limiting groove is provided on the inner wall of the groove 801. One end of the guide cylinder 803 inserted into the groove 801 is fixedly connected with a protrusion, which slides in the limiting groove to prevent the guide cylinder 803 from detaching from the groove 801, further guiding the rebound ring 804, and ensuring the vertical elastic force of the return spring 802.

[0055] The working principle of this embodiment is: first, tighten the connecting head 11 and the connecting sleeve 9 threads to make the first contact 13 and the second contact 14 dock. After tightening, the contact ring 1003 is inserted into the annular groove 1001, and the outer end of the contact ring 1003 is in contact with the sealing gasket 1002. The sealing gasket 1002 is made of silicone material, so that after the connecting sleeve 9 is connected to the connecting head 11, the end can play a good sealing role, thereby playing a waterproof role when used outdoors. It should be noted that when the connecting sleeve 9 and the connecting head 11 are tightened, the two second deflection positioning blocks 15 are aligned with the two second straight groove portions 161 respectively. At this time, the sliding sleeve 3 is pushed toward the direction of the connecting sleeve 9, and the two first deflection positioning blocks 4 slide to the other end of the two first straight groove portions 51, and the two second deflection positioning blocks 15 slide to the other end of the two second straight groove portions 161 (at this time, when the worker applies force, several return springs 802 retract, and the rebound ring 804 is attached to one end of the connecting sleeve 9), and then the sliding sleeve 3 and the protective sleeve 6 are rotated ninety degrees, so that the two first deflection positioning blocks 4 slide to the other end of the two first arc groove portions 52, and the two second deflection positioning blocks 15 slide to the other end of the two second arc groove portions 162 Finally, the sliding sleeve 3 and the protective sleeve 6 are released. Under the action of the rebound force of the return springs 802, the rebound ring 804 moves away from the connecting sleeve 9, so that the protective ring 805 exerts a reverse driving force on the inner end of the sliding sleeve 3, so that the two first deflection positioning blocks 4 slide into the two first deflection grooves 53, and the two second deflection positioning blocks 15 slide into the two second deflection grooves 163 respectively; at this time, the sliding sleeve 3 is positioned on the side wall of the first inner sleeve 201, and the protective sleeve 6 is positioned on the side wall of the positioning sleeve 17. Since the sliding sleeve 3 is fixedly connected to the protective sleeve 6, the first inner sleeve 201 is fixedly connected to the connecting sleeve 9, so that the connecting sleeve 9 and the connector 11 are always kept in a relatively fixed state under the action of the sliding sleeve 3 and the protective sleeve 6. It effectively prevents the connector 11 from rotating in the opposite direction relative to the connecting sleeve 9 and becoming loose.

[0056] When the cable is pulled by external force, under the protection of traditional sleeves, the connector will be directly subjected to the outward expansion force, which will cause damage to the connector. In the present application, since the two second deflection positioning blocks 15 are axially limited in the two second deflection grooves 163 respectively, if the first cable 101 and the second cable 102 are pulled, the pulling force will act on the sliding sleeve 3, the protective sleeve 6, and the positioning sleeve 17, thereby protecting the connecting sleeve 9 and the connector 11, making the axial connection between the connecting sleeve 9 and the connector 11 more stable, and thus the first cable 101 and the second cable 102 maintain a good connection state.

[0057] The protective sleeve of the present application not only has a stable connection state and good protection effect, but also is easy to disassemble, which is convenient for subsequent maintenance and inspection. The specific disassembly method is that the worker applies force to push the sleeve 3 toward the end of the second cable 102. At this time, the protective ring 805 and the rebound ring 804 move close to the connecting sleeve 9 under the extrusion of the sleeve 3, so that the two first deflection positioning blocks 4 slide into the two first arc grooves 52, and the two second deflection positioning blocks 15 slide into the two second arc grooves 162. Then, the sleeve 3 is rotated in the opposite direction, so that the two first deflection positioning blocks 4 slide to the other end of the two first arc grooves 52, and the two second deflection positioning blocks 15 slide to the other end of the two second arc grooves 162. In the next step, the sleeve 3 is slid toward the direction of the first cable 101. At this time, the two first deflection positioning blocks 4 slide to the other end of the two first straight grooves 51, and the two second deflection positioning blocks 15 are respectively separated from the two second straight grooves 161, and the protective sleeve 6 is separated from the positioning sleeve 17. Then, the connector 11 can be unscrewed.

Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
