A signal cable with replaceable cores

Abstract

This utility model discloses a signal cable with replaceable core wires, including an outer protective sleeve and core wires. The inner wall of the outer protective sleeve is fixedly connected to a shielding sheath, and the outer wall of the outer protective sleeve is fixedly connected to a fixing shell. A fixing mechanism is provided on the outer wall of the outer protective sleeve, and a fixing sleeve is threadedly connected to the outer wall of the fixing shell. Rotating a knob causes a lead screw to rotate, which in turn causes a second arc-shaped clamping plate to disengage from the core wires. Rotating the connecting shell causes the fixing sleeve to disengage from the threaded connection with the fixing shell. Pressing the first arc-shaped clamping plate inward causes the first arc-shaped clamping plate to move a moving column and compress a first spring, simultaneously disengaging the first arc-shaped clamping plate from the core wires. This facilitates core wire replacement by operators and ensures core wire stability during use after replacement.

Description

Technical Field

[0001] This utility model relates to the field of signal cable technology, specifically to a signal cable with replaceable cores. Background Technology

[0002] A signal cable is a tool for transmitting signals. Generally, signal cables transmit very small signals. To prevent interference, signal cables have an outer shielding layer, which is the shielding layer covering the conductor. This shielding layer is typically made of conductive cloth, woven copper mesh, or copper foil (aluminum). The shielding layer needs to be grounded so that external interference signals can be conducted to the ground, preventing interference signals from entering the inner conductor and reducing signal loss during transmission.

[0003] Authorization announcement number CN214753110U discloses a signal cable with replaceable cores, including cores and a detachable shielding sheath. The detachable shielding sheath is covered by an outer cable protective sleeve, and one end of the outer protective sleeve has an flared edge strip. The core is located inside the detachable shielding sheath, and its outer side is covered by shielding tape. The flared edge strip has an easy-tear slit. This utility model features an flared edge strip at one end of the cable's outer protective sleeve, with an easy-tear slit. The flared edge strip can be torn open through the slit, allowing direct gripping and removal of the detachable shielding sheath for replacement. The outer side of the detachable shielding sheath has a protrusion for easy pulling control, and the core is covered inside the detachable shielding sheath, facilitating complete core replacement.

[0004] In the above technical solution, the removable shielding sheath is easily pulled out and controlled, and the wire core is wrapped inside the removable shielding sheath, making it easy to replace the entire wire core. However, when pulling out the shielding sheath, it is necessary to tear open the flared edge strip through the easy-tear gap, which damages the outer protective sheath of the cable. Furthermore, the wire core is not fixed inside, which can easily cause its position to shift, affecting the normal use of the signal cable. Utility Model Content

[0005] The purpose of this invention is to provide a signal cable with replaceable cores to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a signal cable with replaceable cores, comprising an outer protective sheath and cores, wherein a shielding sheath is fixedly connected to the inner wall of the outer protective sheath, a fixed outer shell is fixedly connected to the outer wall of the outer protective sheath, a fixing mechanism is provided on the outer wall of the outer protective sheath, a fixing sleeve is threadedly connected to the outer wall of the fixed outer shell, and a connecting outer shell is fixedly connected to the outer wall of the fixing sleeve.

[0007] As a further preferred embodiment of this technical solution, the inner wall of the fixing sleeve begins to have threaded grooves, the inner wall of the connecting shell begins to have perforations, the inner wall of the connecting shell is fixedly connected to a fixing block, and the top of the inner wall of the fixing block is fixedly connected to a first spring.

[0008] As a further preferred embodiment of this technical solution, a movable column is fixedly connected to the end of the first spring away from the fixed block, a first arc-shaped clamping plate is fixedly connected to the bottom end of the movable column, and a column is fixedly connected to the inner wall of the connecting shell.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the column is slidably connected to a movable rod, the inner wall of the movable rod is threaded through and connected to a lead screw, the outer wall of the lead screw is fixedly connected to a knob, and the outer wall of the movable rod is fixedly connected to a second arc-shaped clamping plate.

[0010] As a further preferred embodiment of this technical solution, the outer wall of the connecting housing is provided with a locking mechanism, and the outer wall of the knob is provided with a positioning hole.

[0011] As a further preferred embodiment of this technical solution, a connecting rod is fixedly connected to the outer wall of the connecting housing, and a second spring is fixedly connected to the inner wall of the connecting rod. A limit plate is fixedly connected to the end of the second spring away from the inner wall of the connecting rod.

[0012] As a further preferred embodiment of this technical solution, a fixing rod is fixedly connected to the outer wall of the limiting plate, a connecting arm is fixedly connected to the outer wall of the fixing rod, and a positioning block is fixedly connected to the outer wall of the connecting arm.

[0013] This utility model provides a signal cable with replaceable wire cores, which has the following advantages:

[0014] (1) This utility model rotates a knob, which drives the lead screw to rotate. The rotation of the lead screw causes the second arc-shaped clamping plate to disengage from the wire core. The connecting shell is rotated, which causes the fixing sleeve to disengage from the threaded connection of the fixing shell. The first arc-shaped clamping plate is pressed inward. The first arc-shaped clamping plate drives the moving column to squeeze the first spring. At the same time, the first arc-shaped clamping plate disengages from the wire core, which makes it convenient for the staff to replace the wire core. After the replacement is completed, the wire core can be kept stable during use.

[0015] (2) By pulling the connecting arm outward, the connecting arm causes the positioning block to disengage from the inner wall of the positioning hole. At the same time, the connecting arm causes the fixing rod to move outward. The movement of the fixing rod causes the limiting plate to move inside the connecting rod. The movement of the limiting plate causes the second spring to be in a stretched state, and the knob is released from the lock. The positioning block can be used to lock the knob, further assisting in the stability of the wire core. Attached Figure Description

The cable outer protective sleeve 1 has a shielding sleeve 4 fixedly connected to its inner wall, a fixing shell 7 fixedly connected to its outer wall, a fixing mechanism 5 provided on its outer wall, a fixing sleeve 52 threadedly connected to its outer wall, and a connecting shell 2 fixedly connected to its outer wall.

[0023] Among them, the inner wall of the fixing sleeve 52 has a threaded groove 53, the inner wall of the connecting shell 2 has a through hole 51, the inner wall of the connecting shell 2 is fixedly connected to a fixing block 54, and the top of the inner wall of the fixing block 54 is fixedly connected to a first spring 55.

[0024] The through hole 51 allows the wire core 3 to pass through, thus facilitating the adjustment of the exposed length of the wire core 3.

[0025] Among them, the end of the first spring 55 away from the fixed block 54 is fixedly connected to the movable column 56, the bottom end of the movable column 56 is fixedly connected to the first arc-shaped clamping plate 57, and the inner wall of the connecting shell 2 is fixedly connected to the column 58.

[0026] The first spring 55, relying on its own elasticity, can drive the first arc-shaped clamping plate 57 to stabilize the wire core 3.

[0027] Among them, the inner wall of the column 58 is slidably connected to the movable rod 59, the inner wall of the movable rod 59 is threaded through and connected to the lead screw 510, the outer wall of the lead screw 510 is fixedly connected to the knob 511, and the outer wall of the movable rod 59 is fixedly connected to the second arc-shaped clamping plate 512.

[0028] The lead screw 510, when rotated, can drive the movable rod 59 to move inside the column 58.

[0029] The outer wall of the connecting housing 2 is provided with a locking mechanism 6, and the outer wall of the knob 511 has a positioning hole 61.

[0030] The locking mechanism 6 can restrict the movement of the knob 511.

[0031] The outer wall of the connecting housing 2 is fixedly connected to a connecting rod 62, the inner wall of the connecting rod 62 is fixedly connected to a second spring 63, and the end of the second spring 63 away from the inner wall of the connecting rod 62 is fixedly connected to a limit plate 64.

[0032] The limiting plate 64 is slidably connected to the inside of the connecting rod 62, thereby restricting the movement trajectory of the fixed rod 65.

[0036] When using the device, if it is necessary to replace the core 3, pull the connecting arm 66 outward. The connecting arm 66 will cause the positioning block 67 to disengage from the inner wall of the positioning hole 61. At the same time, the connecting arm 66 will cause the fixing rod 65 to move outward. The movement of the fixing rod 65 will cause the limiting plate 64 to move inside the connecting rod 62. The movement of the limiting plate 64 will cause the second spring 63 to be in a stretched state. At this time, the knob 511 will disengage from the lock. Rotating the knob 511 will cause the lead screw 510 to rotate. The rotation of the lead screw 510 will cause the second arc-shaped clamping plate 512 to disengage from the core 3. Rotating the connecting shell 2 will cause the fixing sleeve 52 to disengage from the threaded connection with the fixing shell 7. Press the first arc-shaped clamping plate 57 inward. The first arc-shaped clamping plate 57 will cause the moving column 56 to squeeze the first spring 55. At the same time, the first arc-shaped clamping plate 57 will disengage from the clamping of the core 3, making it easier for the staff to replace the core 3. After the replacement is completed, the core 3 can be kept stable during use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
