During large-scale installation or maintenance, each connection must be crimped or stripped using tools one by one, which is time-consuming and inefficient. In view of this, the present invention proposes a quick connector for coaxial cable installation. Utility Model Content

[0029] Example

[0030] like Figures 1 to 3As shown, the utility model proposes a quick connector for coaxial cable installation, including a cable body 1, the cable body 1 including an inner conductor 11, an inner insulating layer 12, an outer conductor 13 and an outer insulating layer 14. This is the prior art and will not be described in detail here. It also includes a connecting head 2 arranged at the connecting end of the cable body 1, the connecting head 2 including a fixed sleeve 21 sleeved on one end of the outer insulating layer 14, and a certain length of outer conductor 13 is clamped between the inner side of the fixed sleeve 21 and the outer insulating layer 14, so that the outer conductor 13 is tightly connected to the fixed sleeve 21. Two groups of deformation grooves 22 are provided on the fixed sleeve 21, and the two groups of deformation grooves 22 are symmetrically arranged so that the fixed sleeve 21 can be squeezed inward. A threaded sleeve 23 is threadedly connected to the fixed sleeve 21. When the threaded sleeve 23 rotates, it can drive the fixed sleeve 21 to squeeze the inner outer insulating layer 14, so that the position of the connecting head 2 is fixed. Two groups of connecting rods 24 are fixedly connected to one side of the fixing sleeve 21 away from the outer insulating layer 14 . The two groups of connecting rods 24 are symmetrically arranged. The connecting rods 24 are connected to the outer conductor 13 , so that the connecting rods 24 can connect the outer conductor 13 after connection.

[0031] Furthermore, the above-mentioned quick connector also includes a fixing component 3, and the connecting head 2 is inserted into the fixing component 3 to achieve quick installation of the cable body 1. The fixing component 3 includes a fixed fixing plate 31, and the fixing plate 31 is fixed at the position where the cable body 1 needs to be connected. A positioning sleeve 32 is fixedly connected to the side of the fixing plate 31 close to the cable body 1, and the position of the positioning sleeve 32 is also fixed. Two groups of first clamps 33 are provided on the inner side of the positioning sleeve 32, and the two groups of first clamps 33 are symmetrically arranged on both sides of the inner conductor 11, and the positions of the first clamps 33 are also fixed. The inner conductor 11 is slidably connected between the two groups of first clamps 33, and the inner conductor 11 contacts the first clamp 33 to achieve connection of the inner conductor 11. At the same time, the two groups of first clamps 33 squeeze the inner conductor 11 after approaching to achieve a tight connection. Two sets of partition plates 34 are symmetrically disposed on either side of the inner conductor 11. A second clamping block 35 is disposed on the side of the partition plates 34 away from the inner conductor 11. The connecting rod 24 is slidably connected between the partition plates 34 and the second clamping block 35 to facilitate insertion of the cable body 1. The outer conductor 13 is connected after the connecting rod 24 contacts the partition plates 34 and the second clamping block 35. The partition plates 34 and the second clamping block 35 are both disposed inside the positioning sleeve 32. The two sets of partition plates 34 are connected by connecting wires on the back side of the fixed plate 31. The two sets of partition plates 34 are also connected to the two sets of second clamping blocks 35 by connecting wires on the back side of the fixed plate 31, ensuring circuit integrity and preventing interference between the inner conductor 11 and the outer conductor 13.

[0032] Further, the connecting joint further comprises a locking mechanism 4 arranged on the fixing assembly 3, which is used to drive the fixing assembly 3 to press the connecting end of the cable body 1 to be fixed. The locking mechanism 4 comprises a locking sleeve 41 which is screwed to the inner side of the positioning sleeve 32, and which can move along the length direction of the locking sleeve 41 while rotating. The outer ring of the locking sleeve 41 is fixedly connected with a rotating ring 42, which is arranged to facilitate the rotation of the locking sleeve 41. The inner wall of the locking sleeve 41 is fixedly connected with a pressing ring 43, which moves synchronously with the locking sleeve 41. The cross section of the pressing ring 43 is a right trapezoid, and the first clamping block 33 and the second clamping block 35 are provided with corresponding bevels 44 corresponding to the pressing ring 43, so that the pressing ring 43 can press the first clamping block 33 and the second clamping block 35 through the bevels 44 when moving, so that the two groups of first clamping blocks 33 are close to and press the inner conductor 11, and the two groups of second clamping blocks 35 are close to the partition plate 34 and press the connecting rod 24, so that the connection between the inner conductor 11 and the outer conductor 13 is tight, and the reliability of the connection is ensured.

[0033] In the embodiment, when connecting, the inner conductor 11 is aligned with the middle position of the two groups of first clamping blocks 33, and the connecting rod 24 is aligned with the position between the partition plate 34 and the second clamping block 35, and then the inner conductor 11 and the connecting rod 24 are inserted into the inner side of the positioning sleeve 32. Then the rotating ring 42 is rotated, and the rotating ring 42 drives the locking sleeve 41 to rotate synchronously. Since the locking sleeve 41 is screwed to the positioning sleeve 32, the locking sleeve 41 also moves close to the fixed plate 31 while rotating, and drives the pressing ring 43 to rotate while moving close to the fixed plate 31, so that the pressing ring 43 contacts the bevels 44, thereby pressing the first clamping block 33 and the second clamping block 35. At this time, the two groups of first clamping blocks 33 are close to the middle position and press the inner conductor 11, and the two groups of second clamping blocks 35 are close to the partition plate 34 and press the connecting rod 24, thereby realizing the rapid installation and connection of the cable body 1.

[0034] The above specific embodiments are only optional embodiments of the present application, and based on the technical solutions of the present application and the related inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
