[0008] As a further embodiment of this utility model, a rubber pad is provided on the top of the lower protective shell, and an installation groove is provided on the inner side of the lower protective shell away from the screw strip. Two limiting rods are fixedly connected to the installation groove, and the same locking buckle is slidably fitted on the circumferential surface of the two limiting rods. The locking buckle has a round hole that matches the two limiting rods. A first spring is provided at one end of the two limiting rods near the lower protective shell, and the same limiting block is fixedly connected to the other end of the two limiting rods. The locking buckle matches the screw strip.

[0009] As a further embodiment of this utility model, the bottom of the upper protective shell is provided with a second arc-shaped opening at both ends. The top of the inner side of the upper protective shell is fixedly connected with a second fixing strip near both ends. The two ends of the two second fixing strips are fixedly connected with a second sliding rod near the upper protective shell. The same second arc-shaped push plate is slidably sleeved on the circumferential surface of the two second sliding rods on the same side.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Reference Figures 1-4 A cable connector protection device includes a lower protective shell 1, with an upper protective shell 2 rotatably connected to one side of the top of the lower protective shell 1 via a hinge. Both ends of the lower protective shell 1 have first arc-shaped openings 102. A first fixing strip 4 is fixedly connected to the bottom inner side of the lower protective shell 1 near both ends. Each first fixing strip 4 has a first sliding rod 401 fixedly connected to both ends on the side near the end of the lower protective shell 1. The same first arc-shaped push plate 402 is slidably fitted onto the circumferential surface of two first sliding rods 401 at the same end. The two first arc-shaped push plates 402... Each end is provided with a round hole that matches the first slide rod 401. Both ends of the top of the two first arc-shaped push plates 402 are provided with slots 405. The ends of the two first arc-shaped push plates 402 that are far apart from each other are fixedly connected with first semi-conical rubber plugs 403. The two first semi-conical rubber plugs 403 are slidably connected in the adjacent first arc-shaped openings 102. The ends of the two first semi-conical rubber plugs 403 that are far apart from each other are provided with first notches 404. The first notches 404 facilitate the retraction of the first semi-conical rubber plugs 403.

[0023] In this embodiment, a single lead screw 3 is rotatably connected between the two sides of the bottom center of the inner side of the lower protective shell 1. A threaded connecting strip 302 is threaded onto the circumferential surface of the lead screw 3. The threaded connecting strip 302 has a threaded hole that matches the lead screw 3. Connecting rods 304 are rotatably connected to both sides of one end of the threaded connecting strip 302. The other ends of the two connecting rods 304 are rotatably connected to one side of the adjacent first arc-shaped push plate 402. One end of the lead screw 3 passes through the lower protective shell 1 and is fixedly connected with an internal hexagon bolt 301. A circular hole that matches the lead screw 3 is opened on the lower protective shell 1.

[0024] In this embodiment, a rubber pad 101 is provided on the top of the lower protective shell 1. An installation groove is provided on the inner side of the lower protective shell 1 away from the screw strip 302. Two limiting rods 5 are fixedly connected to the installation groove. The same latch 502 is slidably fitted on the circumferential surface of the two limiting rods 5. A round hole adapted to the two limiting rods 5 is provided on the latch 502. A first spring 501 is provided at one end of the two limiting rods 5 near the lower protective shell 1. The same limiting block is fixedly connected to the other end of the two limiting rods 5. The latch 502 is adapted to the screw strip 302.

[0025] In this embodiment, the upper protective shell 2 has a second arc-shaped opening 201 at both ends of its bottom. The upper protective shell 2 has a second fixing strip 6 fixedly connected to the top of its inner side near both ends. The two ends of the two second fixing strips 6 are fixedly connected to the adjacent ends of the upper protective shell 2. The same second arc-shaped push plate 601 is slidably sleeved on the circumferential surface of the two second slide rods 602 on the same side. The two second arc-shaped push plates 601 have round holes that are adapted to the second slide rods 602. The end of each second slide rod 602 near the upper protective shell 2 is sleeved with a second spring 603. The setting of the second spring 603 makes the second arc-shaped push plate 601 in a stable position when the upper protective shell 2 is opened, which facilitates the engagement of the locking block 604 and the locking groove 405. The bottom ends of each second arc-shaped push plate 601 are fixedly connected to the locking block 604, and each locking block 604 is adapted to the locking groove 405.

[0026] In this embodiment, a second semi-conical rubber plug 7 is fixedly connected to one end of each of the two second arc-shaped push plates 601 that are far apart from each other. The two second semi-conical rubber plugs 7 are adapted to the second arc-shaped opening 201. A second notch 701 is provided at one end of each of the two second semi-conical rubber plugs 7 that are far apart from each other. The setting of the second notch 701 facilitates the compression and contraction of the second semi-conical rubber plug 7.

[0027] In this embodiment, a lock hole 202 is provided at the middle of the inner side of the upper protective shell 2 away from the hinge, and the lock hole 202 is adapted to the latch 502. The setting of the latch 502 and the lock hole 202 makes it possible that when the internal hexagonal bolt 301 is rotated, the first semi-conical rubber plug 403 and the second semi-conical rubber plug 7 on both sides seal the cables at both ends, and finally close the lower protective shell 1 and the upper protective shell 2.

[0028] Working principle: When using this device, place the lower protective shell 1 at the cable connector, ensuring the connector is inside the lower protective shell 1. The cables on both sides are respectively located in the first semi-conical rubber plugs 403 at both ends of the lower protective shell 1. Then close the upper protective shell 2. When the upper protective shell 2 is closed, the two locking blocks 604 of the second arc-shaped push plate 601 on the same side engage with the locking grooves 405 at the top of the first arc-shaped push plate 402 on the same end. At this time, use a tool to rotate the hexagonal socket bolt 301, causing the screw 3 to move with the threaded rod 302. Through the setting of the two connecting rods 304, the first arc-shaped push plates 402 on both sides are pushed away from each other, causing the two first semi-conical rubber plugs 403 to move along the first arc-shaped opening 102. Under the action of the first arc-shaped opening 102, the first semi-conical rubber plugs 403 move away from each other. As the outer end of the rubber plug 403 gradually compresses and closes, the first notch 404 facilitates better closure of the first semi-conical rubber plug 403. Simultaneously, when the first arc-shaped push plates 402 move away from each other, the second arc-shaped push plates 601 on both sides of the upper protective shell 2 move synchronously through the slot 405 and the block 604. Through the cooperation of the second semi-conical rubber plug 7 and the first semi-conical rubber plug 403, the gap between the cables at both ends of the connector and the lower protective shell 1 and the upper protective shell 2 is eliminated and sealed until the two connecting rods 304 straighten. At the same time, when the screw rod 302 moves, it will push the latch 502, causing the latch 502 to move until the top of the latch 502 is engaged in the locking hole 202, so that the upper protective shell 2 and the lower protective shell 1 are closed and will not separate, thereby protecting the connector.
