The diameter of the inner end of the grip plate pieces 44 is further reduced while unfolding, so that each grip plate piece 44 presses the outer circumferential surface of the aluminum tube of the cable to bite, so that the cable does not come off the body 10 and is connected stably. Can be maintained. The first grip plate piece 44A and the second grip plate piece 44B of the spring plate 40 are elastically stretched forward in the pressed state, and the first grip plate piece 44A and the second grip plate piece ( As the inner end diameter of the 44B) is further reduced, each of the first grip plate pieces 44A and the second grip plate pieces 44B press the outer circumferential surface of the aluminum tube of the cable to bite, so that the cable is moved from the body 10 It can be maintained in a stable connected state without falling out.

Therefore, if the cable connector according to the present invention is to connect a cable, when the back nut 30 is pressed and the cable is inserted into the back nut 30, and then the back nut 30 is released, Since the back nut 30 automatically advances to the original position by the spring plate 40, and the spring plate 40 grips the cable to maintain the connection state, the effect of eliminating a lot of inconvenience and hassle in connecting the cable There is. Since it is a one-touch connection method in which the cable is connected while the back nut 30 is pressed, a lot of inconvenience and hassle in the screw-type fastening operation for connection of the cable does not occur at all.

In addition, due to the one-touch connection structure of the cable, it is possible to prevent the occurrence of a connection failure because deformation is not applied to the electric wire (CBT) and the pin 20 inside the cable that may occur during the connection process of the cable. Conventionally, there are problems such as poor connection and communication failure due to deformation on the electric wire and pin 20 inside the cable that were already connected due to the movement occurring in the process of screwing the nut. The invention is that this problem does not occur at all.

In addition, the present invention allows the back nut 30 to be arbitrarily released or the spring plate 40 to grip the conductive line (copper line) of the cable due to minute vibrations generated during the operation of the equipment (communication equipment) or force applied from the outside. Since the state is not released, a very serious problem in which the function as a cable connector cannot be properly performed can be solved. In the past, the connection of the cable is maintained by the screw-type connection of the nut. Therefore, the nut is loosened arbitrarily by a slight vibration generated during the operation of the equipment or external force, and the tightening force is lost. As the connection between the conducting lines inside the cable is released, a very serious problem occurs in that the function as a cable connector cannot be properly performed, but in the present invention, such a problem does not occur at all.

In addition, the present invention is not a structure in which the body 10, which is a main body as a medium connecting the cable and the pin 20, is composed of a single sleeve structure, and the back nut 30 is screwed to the body 10. Compared to the existing one, the number of parts can be further reduced, and as the number of parts is reduced, the manufacturing process can be shortened and the unit cost can be reduced.

In addition, in the present invention, the first insert ring 50 has a tapered portion 52 therein, and the outer surface of the retreat stop step 34 provided on the outer peripheral surface of the front end side of the back nut 30 is a guide tapered surface ( 34GT), and the spring plate 40 is disposed between the tapered portion 52 inside the first insert ring 50 and the guide tapered surface 34GT of the back nut 30, and when pressing the back nut The spring plate 40 opens more smoothly by the tapered portion 52 inside the first insert ring 50 and the guide tapered surface 34GT of the back nut 30, and the back nut 30 returns to its original position. Even when reversing, the spring plate 40 can be spread more smoothly. The grip plate pieces 44 of the spring plate 40 are disposed between the tapered portion 52 inside the first insert ring 50 and the guide tapered surface 34GT of the back nut 30 to secure the back nut 30. When pressed, it is more smoothly pressed, and when the back nut 30 is retracted, the grip plate pieces 44 of the spring plate 40 are spread more smoothly. Specifically, the first grip plate piece 44A and the second grip plate piece 44B of the spring plate 40 are the tapered portions 52 inside the first insert ring 50 and the guide taper of the back nut 30 The first grip plate piece 44A and the second grip plate piece 44B of the spring plate 40 are pressed more smoothly when the back nut 30 is pressed by the surface 34GT, and when the back nut 30 is retracted. ) Are spread out more smoothly.

In addition, the first insert ring 50 is coupled to the inside of the body 10, the second insert ring 60 is also coupled to the inside of the body 10, and the spring plate 40 is the first insert ring 50 And the second insert ring (60), so the coupling structure between the spring plate (40) and the first insert ring (50) and the second insert ring (60) is solid and simplifies the assembly process. There is also an effect.

In addition, if the first insert ring 50 is inserted into the body 10 while supporting the insulator 18 on the inward stepped jaw 12 inside the body 10, the insulator 18 is firmly attached to the body ( 10) Since it can be fixed inside, there is a more convenient and quick effect when fixing the insulator 18 inside the body 10.

The sliding stop step 62 protruding from the inner circumferential surface of the second insert ring 60 is provided with a sliding taper surface 62ST inclined downward in a direction away from the direction in which the back nut 30 is inserted, and the back nut ( 30) The retreat stop step 34 protruding from the outer circumferential surface is provided with a guide taper surface 34GT that is inclined downward from the base end of the back nut 30 toward the front end, so that the back nut 30 is attached to the base end of the body 10. When inserted and pushed in from the side, the guide taper surface 34GT of the retreat stop step 34 slides along the sliding taper surface 62ST of the sliding stop step 62, so that the back nut 30 is inserted into the body ( 10) can be pushed from the base end of the second insert ring 60 more easily and smoothly. Due to the guide taper surface 34GT of the retreat stop step 34 and the sliding taper surface 62ST of the sliding stop step 62, the back nut 30 is inserted from the base end of the body 10 to insert the second insert ring ( 60) is easier to combine. And, after the guide taper surface 34GT of the retreat stop step 34 completely crosses the sliding taper surface 62ST of the sliding stop step 62, the retreat stop step at the front end of the sliding stop step 62 is a right angle. Since the rear end, which is the right angle surface of 34, is caught, the case of the back nut 30 being removed toward the base end of the body 10 does not occur after the back nut 30 is coupled to the second insert ring 60. .

In the spring plate 40, the grip plate pieces 44 are disposed between a plurality of first grip plate pieces 44A arranged along the circumferential direction of the rim piece 42 and the first grip plate pieces 44A. It is composed of a plurality of second grip plate pieces (44B) relatively smaller in width than the first grip plate piece (44A), the first grip plate piece (44A) on the outer surface of the electric wire inside the cable. Since the contact area of the inner end of the second grip plate piece 44B is larger than the contact area of the inner end, the electric wire inside the cable may be prevented by micro-vibration during operation of the equipment or external force. As a result, even if an action to be pulled out toward the base end of the body 10 occurs, the conductive line of the cable is gripped with a greater force by the second grip plate pieces 44B having a relatively larger width. The case where the electric wire is about to fall toward the base end of the body 10 is more reliably prevented. In particular, since the first grip plate pieces 44A and the second grip plate pieces 44B are alternately arranged on the spring plate 40, the first grip plate pieces ( 44A) hold the electric wire of the cable with a uniformly distributed grip force, while the second grip plate pieces 44B cover the outer surface of the electric wire of the cable with a larger area than the first grip plate pieces 44A. Since the structure holds the grip force evenly distributed, it is more reliably prevented that the cable is removed from the body 10 due to micro-vibration during vibration of the device or external force.

In addition, the spring plate 40 has a grip guide hole 46 extending a predetermined length from the circumference of the rim piece 42 toward the inner end of the second grip plate piece 44B, and the back nut 30 ) When the first grip plate piece 44A and the second grip plate piece 44B are pressed and opened by the front end of the back nut 30, the plurality of second grip plate pieces 44B are formed into the grip guide holes ( 46), the grip force is uniformly distributed with the first grip plate piece 44A, so that the entire outer surface of the electric wire of the cable can be more reliably and uniformly held. Due to the grip guide hole 46, some of the second grip plate pieces 44B among the plurality of second grip plate pieces 44B grip the electric wire of the cable with a relatively small force, and the second grip of the other part The plate piece 44B does not grip the electric wire of the cable with a relatively larger force than the some of the second grip plate pieces 44B, and all of the second grip plate pieces 44B have a uniform force. Since it can hold the outer surface of the cable, the cable keeps the connection state with the inner pin 20 more firmly.
