Abstract
A coaxial cable connector comprises a connecting member 5, two insulating sleeves 6 holding both sides of the connecting member 5, a tubular casing 7 for containing the connecting member 5 and the insulating sleeves 6, and a cap 8 pressing one side of the tubular casing 7. The above connecting member 5 is composed of a metal plate 54 which is coiled to form a hollow tube. There is a contact portion near each tail end of the above connecting member 5, wherein there is a plurality of elastic metal parts 58 which are spaced by slots 53. When a cable conductor is inserted into the connecting member 5, the cable conductors with different diameters can appropriately extend the contact portion of the connecting member 5 in the radius direction. A better contacting effect is indeed achieved with the tightly circular contact of the cable conductor and the connecting member 5. The coaxial cable connector of the present invention can improve the drawbacks of the conventional coaxial cable connectors, which are the elastic fatigue of the connecting plate and the induced bad contact effect.
Description
1 COAXIAL CABLE CONNECTOR 2336479 The present invention relates to an
improved coaxial cable connector, particularly used to connect two coaxial cables for elongating the length.
0 The coaxial cable connector is used to connect the cables for transmitting the signals in many television systems, such as the conventional cable television system (CATV), master antenna television system (MATV), or video systems. Fig. 1 is a coaxial cable connector of the prior art, which includes a tubular casing 1 with outer thread for screwing, a connecting plate 2, and a dielectric jacket 3 inside the tubular casing 1. The connecting plate 2 is snugly plugged to the dielectric jacket 3. The connecting plate 2 is made by compressing an elastic sheet metal as a cramp with elasticity, and is normally under clamping status. When a cable conductor 4 inserts through the tubular casing 1 into the connecting plate 2, the cable conductor 4 is clamped by the connecting plate 2 with its elastic force, and thereby transmits the signal. With the coaxial cable connector of the prior art, there are the faliowing disadvantages:
1. After a long-term use of the conventional coaxial cable connector shown above, the elastic fatigue of the connecting plate 2 is easily generated to reduce the quantity of clamping the cable conductor 4.
In Fig. 1, the up and down sides of the cable conductor 4 are clamped by the connecting plate 2, and the left and right sides of the cable conductor 4 are free. Hence, the cable conductor 4 is easily moved left or right by external forces, and the signal connecting effect will be consequently poor.
1 J.
The middle section of the connecting plate 2 is too narrow to be deeply inserted by a cable conductor 4 with longer length.
4 sleeve 6, and it's axis is aligned with the central axis of the connecting member 5. At one end of the insulating sleeve 6, there is a positioning hole 61 which is formed by enlarging the inner radius of the first through hole 60. At the other end, an outward projecting flange 62 is formed. The contact portion 56 of the above connecting member 5 is placed into the first through hole 60 of the insulating sleeve 6, and then the outward cylindrical flanae 52 of the connectincy member 5 and the positioning hole 61 of the insulating sleeve 6 are mutually matched. Besides, the connectina member 5 is electrically isolated with the tubular casiner 7 by the insulating sleeves 6.
In the tubular casing 7, there is a through hole 72. The central axes of the through hole 72, the connecting member 5 and the insulating sleeves 6 are the same. At one end of the tubular casing 7, an inward projecting flange 73 is formed, and at the other end of the tubular casing 7, a setting part 74 is formed by expanding the inner radius of the through hole 72. Outside the middle of the tubular casing., 7, there is the second outward flange 70 for positioning. In addition, the second outward flange 70 divides the outside of the tubular casing 7 into two portions, each of which is formed with outer thread 71. The outer thread 71 is suitable to be screwed with the inner thread of an output or an input terrniinal. The both sides of the connecting member 5 are independently placed into the two sleeves 6, and then they are together placed into the through hole 72 of the tubular casing 7. With the stop of the inward projecting flange 73, one outward pr "ectinc, flange-62 of one sleeve 6 abuts against 01 Z the inner wall of the through hole 72 of the tubular casing 7. Consequently, there exists a ring space between the outward pr jecting flange 62 of the other sleeve 6 and 01 the setting part 74 of the tubular casing 7 for placing the above cap 8. The cap 8 has the second through hole 80 which is aligned with the same central axis of the connecting member 5, the sleeves 6, and the tubular casing 7. An outward flange 81 is formed at one end of the cap 8. The outward flange 81 is inserted into the ring space between the setting part 74 of the tubular casing 7 and the outward projecting flange 62 of one sleeve 6, hence the cap 8 is tightly pressed into the tubular casing 7. The coaxial cable connector is finally assembled.
Please refer to the Fig. 4A and 4B. When use the coaxial connector of the 3 The description is made with reference to the accompanying drawings in which:

Fig. 4B is the cross-section view of the present invention in contact condition.
Please refer to Fig. 2, which shows an improvedcoaxial cable connector. The coaxial cable connector includes a connecting member 5, two insulating sleeves 6 holding both sides of the connecting member 5, a tubular casing 7 for containing the connecting member 5 and the insulating sleeves 6, and a cap 8 pressing one side of the tubular casing 7. The connecting member 5. made by coiling an elastic sheet metal 54 shown in Fig. j to form a hollow tube, has a contact portion 56 near each tail end of the hollow tube. At the opening 57 of the contact portion 56, there are consecutively an inward reducing section 50 with gradually small radius, a contact section 51 with equal radius, and an outward expanding section 55 with gradually large radius, and the contact portion 56 used to clamp the cable conductor 4 is consequently formed. Since the elastic sheet metal 54 possesses a plurality of elastic metal parts 58 that are spaced by a plurality of slots 53, the contact portion 56 can be appropriately extended in its radius direction.. In addition. since the connectina member 5 is formed as a hollow tube, the cable conductors possessing different lengths or diameters can be easily inserted with the same highly contacting effect. Between the two contact portions 56 on both sides of the connecting member 5, there exists an outward cylindrical flange 52 for appropriately positioning the connecting member 5.
The first through hole 60 is formed at the central axis of each above insulating 6
