Two. background technology: along with the sustainable development of national economy and science and technology, the electric power of China, network, communication, post and telecommunications also obtain swift and violent development, and the use amount of various electric power, communication cable is how much multiples and increases.Since cable often adopt folk prescription to or multi-direction transmission, this just exist the cable branch to, the problem of joint, the method and apparatus of cable splice is varied at present, normally used terminal box or junction box, it is fixing that advancing on turnover cable and junction box or the terminal box adopts between the wire hole, the sealing device majority is Sealed casing pipe or dop, sealing sleeve pipe or dop are made by rubber or nylon, there is certain elasticity, though therefore can well seal, but because the specification of cable is a lot, thickness is different, therefore often need supporting sleeve pipe of many kinds or dop in construction, workmen or maintenance personal often need carry a variety of sleeve pipes or dop, carry, use inconvenient, cause certain trouble to work, when particularly running into nonstandard cable, just do not have suitable sleeve pipe or dop, need seek substitute, thereby influence the progress of work, and the sealing effectiveness of substitute does not reach requirement.Therefore, seek a kind of easy to use, connect cable dop quick, applied widely, to increasing work efficiency, guarantee the universal cable dop of the fixedly connected quality of cable, be in demand.The utility model patent of the patent No. 99241096.7, notification number CN2410776Y discloses a kind of novel coaxial shielding cable connector, comprise core pipe, turret head, water proof ring, shell, snap ring and stopper, the core pipe passes pack into of shell of turret head, water proof ring, snap ring is put in people's stopper, and is enclosed in the other end of shell.The utility model is mainly used in the connection coaxial cable, has saved the inconvenience that specific purpose tool brings, and is simple.Can not be used for fixing other cable.
Three. the content of utility model:
The purpose of this utility model: overcome the defective of prior art, a kind of simple in structure, easy to use, good sealing effect is provided, can adapts to the universal cordage dop of plurality of specifications cable.
The technical solution of the utility model: a kind of universal cordage dop, contain collet body, described collet body is for cutting centrum or being formed by connecting by the cylinder at rear portion and the truncated cone of front portion, the center of collet body is provided with cylinder or the cone-shaped hole inner chamber that passes cable, along the circumferential direction be provided with the axial straight joint that runs through the collet body body wall of some at the small end of collet body, this axial straight joint makes the front portion of collet body form the continuous separated dop sheet of head of root, be complementary with described collet body and be provided with cutting ferrule, the small end of described collet body is nested in the cutting ferrule, the cutting ferrule border of an end that enters at cutting ferrule upper chuck body is provided with screw thread, be complementary with described cutting ferrule and screw thread and be provided with clamp nut, the rear end of described clamp nut inwardly is provided with stepped hole, and the internal diameter of described stepped hole is less than the diameter of the big end of collet body.
Described universal cordage dop is provided with the annular groove of some and certain depth, the certain distance in space between the described annular groove on the small end outer surface of collet body.
The cutting ferrule profile of universal cordage dop can be cylinder, and periphery can be established boss; Cutting ferrule profile or be positive multiedge cylinder, its part that cooperates with clamp nut is a cylinder during for positive multiedge cylinder, and it is corresponding that cutting ferrule inner chamber and collet body profile are mated, and it is similar or identical that cutting ferrule inner chamber and collet body are cut the centrum cross sectional shape.
The beneficial effects of the utility model:
1. the utility model is simple in structure, cost is low, and cost is low, can be used in that to be used for continuing of different-diameter cable on various junction boxes or the terminal box fixing, applied widely.Because the axle center of collet body is provided with pre-small post-large circular cone vestibule, during use, can the front cutting of collet body be fallen a part according to the thickness of cable, make dop inner cone vestibule can pass the cable of various diameters, thereby can adapt to cable fixing of plurality of specifications.
2. the utility model good sealing effect, collet body inwall total energy closely contacts with cutting ferrule and cable, therefore realize sealing easily, and the body wall that runs through collet body is provided with the axial straight joint of some, make the front portion of collet body form the continuous and separated dop sheet of head of root, reduce the conflict power that collet body produces when compacted so greatly, increase sealing effectiveness, alleviate the mechanical pressure that cable is produced simultaneously.
3. the outer surface of the utility model collet body front portion is provided with annular groove, is convenient to cutting, can pass the cable of various diameter specifications after the cutting, reduces the kind that needs dop in the engineering construction, is easy to carry, and is easy to use, helps increasing work efficiency.
