Abstract
The utility model discloses a locking screw for a connector, which comprises a double-end screw, a flat nut and a dual-purpose nut, wherein a clamping step is arranged at the central part of the double-end screw; one end of the two-purpose nut is closed; a changing knife port is arranged on the end surface at the closed end of the two-purpose nut; a plurality of convex edges are arranged on the outer wall of the two-purpose nut along the axial direction of the two-purpose nut; and the convex edges are uniformly distributed around the two-purpose nut for a circle to form knurling bringing convenience in screwing with a hand. The locking screw has a simple structure and low cost and is convenient to process; meanwhile, the convex edges are arranged on the outer wall of the dual-purpose nut; the changing knife ports is arranged on the end surface at the closed end of the dual-purpose nut; and during use, the locking screw can be screwed with the hand or with the changing knife more conveniently and can be used for locking the connector more easily.
Description
Technical field
The utility model relates to a kind of screw, relates in particular to a kind of connector locking screw.
Background technology
Existing connector is that what to adopt is loading nut in the plastic body at socket in locking, cartridge screw in the plastic body of plug, earlier nut is installed on the socket, the screw rod of the other TOE of nut passes circuit board, with another nut screwing clamping socket is fixed on the circuit board again, the plug of just good and sound screw is installed on the socket then, the employing instrument turns screw plug and socket is locked, unusual trouble and also very difficult when the such screw and nut of processing so not only, difficulty of processing is big more, causes lock-screw cost height.
The utility model content
The purpose of this utility model just is to provide a kind of handling ease, connector locking screw with low cost and easy to use.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of connector locking screw, comprise a double end screw, a flat nut and a dual-purpose nut, described dowel screw middle part is provided with a screens step, described dual-purpose nut one end sealing, and have on the blind end end face of this dual-purpose nut and change the edge of a knife, its axis direction also is provided with several fins in the outer wall upper edge of dual-purpose nut, and described fin evenly distributed around dual-purpose one week of nut.
Further, the described edge of a knife that changes is yi word pattern or cross.
Compared with prior art, advantage of the present utility model is: simple in structure, with low cost and easy to process, simultaneously, the outer wall of dual-purpose nut is provided with fin, and has on its blind end end face and change the edge of a knife, but both hand-tight make-up in use, availablely again change cutter it is tightened, convenient, and easier of connector locking.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, the utility model comprises a double end screw 1, a flat nut 2 and a dual-purpose nut 3, described dowel screw 1 middle part is provided with a screens step 4, described dual-purpose nut 3 one ends sealing, and have on the blind end end face of this dual-purpose nut 3 and change the edge of a knife 5, its axis direction also is provided with several fins 6 in the outer wall upper edge of dual-purpose nut 3, and described fin 6 evenly distributed around dual-purpose 3 one weeks of nut, form annular knurl, the described edge of a knife 5 that changes is yi word pattern or cross.
Earlier an end of dowel screw 1 is passed hole on the socket during use up to screens step 4 places, again screw is passed circuit board, and tighten with flat nut 2 from back of circuit board, socket is fixed on the circuit board, the other end with dowel screw 1 passes from the preformed hole of plug then, tighten with dual-purpose nut 3 at last, thereby plug and socket is fixed together.So just the nut of connector screw is placed the plastic body outside of connector, not only convenient but also firm, dual-purpose nut 3 outer walls are provided with fin 6, form annular knurl, be convenient to hand and twist, have at the blind end end face of nut and change the edge of a knife 5, make that the also available cutter that changes is twisted when tightening, be user-friendly to, and simple in structure, with low cost.
Claims (2)
1. connector locking screw, comprise a double end screw, a flat nut and a dual-purpose nut, it is characterized in that: described dowel screw middle part is provided with a screens step, described dual-purpose nut one end sealing, and have on the blind end end face of this dual-purpose nut and change the edge of a knife, its axis direction also is provided with several fins in the outer wall upper edge of dual-purpose nut, and described fin evenly distributed around dual-purpose one week of nut.
2. connector locking screw according to claim 1 is characterized in that: the described edge of a knife that changes is yi word pattern or cross.
