Description

Many contact points of continuous coaxial cable connector

Technical field

Relevant a kind of many contact points of the continuous coaxial cable connector of the utility model, in order to connect coaxial cable line to an interfacing part, except guaranteeing the good continuity of signal transmission, more because the many contact point designs of special loop shaped, so that the ring-type nut of coaxial cable connector is when screwing in F joint external screw teeth, screw in smooth and easy and not time-consuming, screw in even without screwing as long as have, good grounded circuit also can be arranged, can make more reliable and stable really the connecting of grounded circuit member of this many contact points of continuous coaxial cable connector.

Background technology

Having now may be under same specification as the cable of signal transmission line, wire rod external diameter with different size, therefore, general coaxial cable connector is wanted this type of cable of simultaneously winding usually, in applicant's U.S. patent application case number 13/274, in 308 " continuity coaxial cable connectors " and U.S. patent application case number front two cases of 13/412,972 " continuous coaxial cable connector with many contact points shell fragment ", namely provide the cable connector of this type.These two kinds of continuity coaxial cable connectors, mainly all be that the annular body front end is formed a necking section, has a chase on this necking section to accommodate a waterproof O type ring or in ring-type nut rear end, to form a chase to accommodate a waterproof O type ring, and a Multi-contact shell fragment is sheathed on the necking section of this annular body, contact end contact with this ring-type nut rear, so that pushing against, the supporting surface of the binding face of ring-type nut and inner annular cylinder is connected as a single entity, when the ring-type nut screws in the F joint of interfacing part, screw in even without screwing as long as have, also good grounded circuit can be arranged, to keep the signal transmission between cable and the interfacing part good, guarantee that the terminal equipment picture can have clearly image.

In these front two cases, the Multi-contact shell fragment of carrying all is to be sheathed on the necking section of this annular body, contact end contact with this ring-type nut rear, so that pushing against, the supporting surface of the binding face of ring-type nut and inner annular cylinder is connected as a single entity, the effect of the tighter then grounded circuit that supports is better, but the screw-in resistance when the ring-type nut screws in interfacing part F joint relatively is also just larger and time-consuming, is unfavorable for that the workmen assembles, and is to be improved.

Take wherein a kind of cable connector 91 of commonly using shown in Figure 1 as example, this type of coaxial cable connector 91 mainly is that cable 90 is combined in a cable connector 91, links with an interfacing part 92 (ginseng Fig. 2) again; The interface that engages of the cable connector 91 of assembling combination cable 90 and described interfacing part 92 mainly is included in cable connector 91 and is provided with a ring-type nut 93 that contains internal screw thread 94,92 of interfacing parts are provided with a F joint 95 that contains external screw teeth 96 at opposed end, both thereby can screw winding and be integral.

According to above-mentioned connecting structure except the center conductor 97 that must make cable 90 peg graft in the default holding shrapnel 98 of above-mentioned F joint 95 connect with settling signal, outside associated components comprises that the above-mentioned subsides section 902 that supports that defaults in cable connector 91 inner annular cylinders 99 must see through end face 903 that ring-type nut 93 screws in external screw teeths 96 and F joint 95 and really screw and connect, cooperate the metal knitted stratum reticulare 901 that defaults in cable 90 to form good grounded circuit, just can keep assembling cable cable connector 91 after 90s and the good signal transmission function between the interfacing part 92.

But in existing connector, the subsides section 902 that supports of above-mentioned cable connector 91 inner annular cylinders 99 has with ground connection connection lead structure between the end face 903 of F joint 95 always and is difficult to really screw contact, or ring-type nut 93 occurs and does not contact from screwing between external screw teeth 96 gets loose the end face 903 of the subsides section 902 that supports that causes ring-type cylinder 99 and F joint 95 in long-term the use, how to make above-mentioned F joint 95 and ring-type cylinder 99 form good grounded circuit, guarantee to have between cable connector 91 and the interfacing part 92 and can stablize the signal transmission function, and when ring-type nut 93 screws in the external screw teeth 96 of F joint 95, screw in the smooth and easy and not time-consuming important topic that becomes this type of connector designer.
