[Technical field to which the invention belongs]

 The present invention provides a kind of introduction pipe, which is an auxiliary part used especially for connecting a coaxial cable and a connector to each other, and when the coaxial cable is inclined and inserted into the connector by the introduction pipe, It relates to an inlet pipe that is correctly calibrated and goes straight into the connector.

[Prior art]

 In systems such as a cable television system, a closed loop television system, a joint antenna television system, and a terminal device, signal transmission using a coaxial cable is required. As shown in FIG. 12, a traditional coaxial cable connector is composed of a cable 10 and a connector 11 (eg, F connector, BNC connector, RCA connector). The operator must effectively insert the cable 10 into the connector 11, insert the conductor 12 and the insulator 13 into the trouser tube body 14, and attach the knitted conductor 15 and the outer sheath 16 to the trouser tube body 14 and The cable 10 is inserted between the end extension portions 17, and finally, the inwardly applied force is applied to the trouser means 18 using a tool, so that the cable 10 is tightly clamped by the rear extension portion 17. However, the diameter of such a main body 14 is slightly larger than the diameter of the insulator 13, so that it is very difficult to introduce the insulator 13 into the main body 14 during insertion and combination by an operator. Also, if the cable 10 is inserted in a slanted shape, it becomes more difficult for a worker to insert the insulator 13 into the jacket tube body 14, and this has been a major problem in assembling. Therefore, it is currently the industry's goal to overcome these shortcomings and increase competitiveness.

[Embodiment of the invention]

 Example 1: Please refer to FIGS. 1, 2, 3 and 4. The introduction tube 30 of the present invention has a hollow body 31 and is made of a plastic material. An accommodation hole 32 is provided in the main body 31, and the accommodation hole 32 is composed of a conical part 321, a fitting part 322, and an introduction part 323. The conical portion 321 is inclined inward from the outside and gradually contracts, and a fitting portion 322 having a relatively large diameter is connected behind the conical portion 321, and an introducing portion that contracts inward from outside behind the fitting portion 322. 323 are connected. Further, at least one convex edge 33 is provided at an outer edge of the main body 31, and a connecting portion between the convex edge 33 and the main body 31 has a slope. As shown in FIGS. 3 and 4, the introduction tube 30 is mounted in the cannulated tube main body 14 of the BNC connector 2, and the protruding edge 33 is located outside the cannulated tube main body 14. When the conductor 12 and the insulator 13 of the coaxial cable 10 are inserted into the BNC connector 2, the insulator 13 presses the introduction tube 30 forward, and the protruding edge 33 is formed by the metal-made sheath tube body 14. The conductor 12 is inserted into the fitting tube 322 by shaving off or directly press-fitting it into the main tube body 14, and the insulator 13 presses the introduction tube 30 forward, and the contact tube 211 is inserted into the fitting tube 322. The conductor 12 is easily inserted into the contact tube 211. If the coaxial cable 10 is obliquely inserted into the connector 2, the conductor 12 of the coaxial cable 10 comes into contact with the conical portion 321 in the introduction tube 30, thereby simultaneously introducing the conductor 12 of the coaxial cable 10. The tube 30 is driven to move forward, and the conical portion 321 of the introduction tube 30 is gradually contracted from outside to inside, so that the conductor 12 of the coaxial cable 10 is gradually and straightly introduced into the center of the main body 14 of the jacket tube. Then, the fitting portion 322 of the introduction tube 30 is provided on the outer diameter of the contact tube 211, and the conductor 12 is accurately inserted into the contact tube 211.

Second Embodiment As shown in FIGS. 5, 6, and 7, the introduction tube 40 is almost the same as that of the first embodiment, except for the design position of the convex edge 42. The rim 42 is provided at an appropriate position on the outer edge of the hollow body 41 so that it comes into contact with the inner wall of the sleeve tube body 14 and its escape is prevented.

Embodiment 3 As shown in FIG. 8 to FIG. 11, an introduction tube 50 is mounted in a hood tube main body 14 of an F connector 11, and the introduction tube 50 is provided with one main body 51. At one end, a ramp 52 is provided, which is easily inserted into the trocar body 14. A receiving hole 53 is provided at the other end, and the receiving hole 53 is composed of an insertion portion 54 and a conical portion 55. In addition, at least one convex edge 56 is provided at an appropriate position on the outer edge of the main body 51, which comes into contact with the inner wall of the trocar main body 14 and prevents its escape. In addition, the connecting portion between the convex edge 56 and the main body 51 has a slope, whereby the introduction pipe is inserted into the jacket tube main body 14 along the slope. When the coaxial cable 10 is inserted straight into the connector 11, the conductor 12 is inserted directly into the insertion portion 54, thereby simultaneously driving the introduction tube 40 to move forward and push it out of the connector 11. That is, the combination work can be completed easily. If the coaxial cable 10 is inserted into the connector at an angle or off center, the conductor 12 first contacts the conical portion 55, thereby calibrating the conductor 12 and inserting it into the insertion portion 54. At the same time, it is pushed out of the connector 11, that is, the assembly work can be completed easily.
