Abstract
The utility model relates to a biconical sleeve and a self-locking type electric joint which are used for connecting electric wires and cables with a controller, a power supply device, etc. The utility model is composed of a joint body 4, biconical lock sleeves 3 and a locking nut 2, wherein one end of the joint body 4 is provided with a wire connecting hole 5 and external screw threads 6, and one end of the locking nut 2 is connected with the joint body 4. The wire connecting hole 5 and the inner wall surface of the other end of the locking nut 2 are respectively provided with internal conical holes 7 and 8 matched with the external cone surfaces of the biconical lock sleeves arranged in the conical holes 7 and 8. The utility model has the advantages of thorough contact of wires and the joint body, tightness and good electric conductivity.
Description
The utility model relates to a kind of electrical connector that electric wire, cable are connected with controller, electric supply installation etc. that is used for.
Existing electrical connector is made up of fittings body and the housing screw two parts that communicate with the fittings body wire connection hole that are installed on the fittings body upper surface.During operation, lead is directly inserted in the wire connection hole of fittings body, tighten the housing screw of its upper end and promptly finish being connected of lead and fittings body.This connected mode lead contacts insufficient, not tight with fittings body, poorly conductive, poor stability, cause accident easily.
The purpose of this utility model is to provide a kind of lead electrical connector abundant with the joint physical efficiency, that closely contact.
The utility model is achieved in that a kind of two-taper ferrule, self-locking electrical connector, is made up of fittings body, biconial lock sleeve and locking nut.Fittings body one end has wire connection hole and is shaped on external screw thread, locking nut one end is connected on the fittings body, be shaped on wire connection hole and the locking nut other end internal face and the corresponding female cone of biconial lock sleeve outer conical surface hole, the biconial lock sleeve places in the conical bore of fittings body and locking nut.During operation, lead is directly inserted in the biconial lock sleeve of this joint, tighten locking nut and get final product.
Compare with existing electrical connector, the utility model adopts the interior biconial lock sleeve of lead and electrical connector to be connected, the version that lock sleeve is connected with fittings body again, when tightening locking nut, nut moves to fittings body and has shortened the distance of nut and fittings body, biconial lock sleeve in the middle of the compressing shrinks, lock sleeve closely is connected with fittings body with locking nut, lock sleeve shrinks to the lead that penetrates again simultaneously, thereby lead and the fully tight purpose that contacts of fittings body have been reached, so good conductivity, fail safe is good.
Fig. 1 is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
As shown in Figure 1, the utility model is made up of fittings body 4, biconial lock sleeve 3 and locking nut 2.Fittings body 4 one ends have wire connection hole 5 and are shaped on external screw thread 6, locking nut 2 one ends are connected on the fittings body 4, be shaped on wire connection hole 5 and locking nut 2 other end internal faces and the corresponding female cone of biconial lock sleeve 3 outer conical surface hole 7,8, the biconial lock sleeve axially have retraction slot 9 and place fittings body 4 and locking nut 2 female cone holes 7,8 in.
During operation, lead is directly inserted in the biconial lock sleeve 3 in this fittings body, tighten locking nut 2 and get final product.
Principle:
When tightening locking nut, nut moves and has shortened initial distance to fittings body, and the biconial lock sleeve in the middle of having oppressed shrinks (design amount of contraction and fluting).Because of the distance of nut and fittings body is shortened, the inner conical hole of the nut at two ends and fittings body fits like a glove with the double end cylindrical taper surface of middle lock sleeve, so the inner conical hole of the nut at two ends and fittings body has played that fixing and locking overlaps the position and as the effect of conducting surface.Simultaneously, the rotation of nut, the shortening of joint intermediate distance, the compressing lock sleeve shrinks to the lead that penetrates, thereby has reached lead purpose abundant with fittings body, that closely contact, has improved its conductivity.
The biconial lock sleeve is done to reduce its contact resistance with the electrolysis copper, improves its electric conductivity.
