CN203377427U - An RJ45 connector plug allowing tool-free spot cable making - Google Patents

Abstract

The utility model discloses an RJ45 connector plug allowing tool-free spot cable making, the RJ45 connector plug comprising an upper base joint member and a lower base joint member, which are in snap fit. The lower base joint member comprises a lower base body, contact members, a locating block and an outer shell; the contact members are installed in the lower base body; and the outer shell is snapped to the outside of the lower base body. The upper baser joint member comprises a cover plate, a pressing block and an upper base body; the pressing block is fixed to the upper base body through a bayonet; and an upper rotating shaft of the cover plate is matched with an upper rotating shaft hole of the upper base body. After wire stripping, a user puts wires in a cable into the upper base joint member; when the upper base joint member is pressed into the lower base joint member, the wires penetrate into piercing grooves of the contact members, and insulating covers of the wires are pierced and copper wires in the wires are contacted with the contact members. The RJ45 connector plug is convenient to use and enables the wires to be pressed into the contact members without special tools. The tail ends press the cable firmly, so that the connection is reliable.

The utility model is by upper, bottom base component two parts form, the bottom base component is by lower base-seat body, contact, locating piece and shell form, contact is installed in lower base-seat body, contact head construction and common RJ45 connector are similar, the tail end contact is provided with and punctures groove, wire insulating barrier in process of press in is subject to certain extruding, when insulating barrier squeezed when broken, copper cash and contact conducting, contact mark row, shift to install, shell is equipped with in the lower base-seat body outside, shell is metal parts, by buckle and lower base-seat body, fix, shell is provided with shell fragment, during use, with the cable shielding layer, contact, signal has been transmitted to shielding action.The top base assembly is comprised of cover plate, briquetting and top base body, briquetting and top base body are fixed by bayonet socket, on cover plate, rotating shaft coordinates with hole on the top base body, cover plate can rotate around the shaft, briquetting is for placing wire, and wire is pressed in contact, cover plate, for the cable outer layer insulated hull is compressed, prevents that cable is drawn out.

When the user uses, cable is peelled off to insulated hull, then the cable inside conductor is packed in top base assembly briquetting corresponding groove, when the top base component is pressed in the bottom base component, in the pressure lower wire of briquetting is thrust contact, contact and wire conducting, finally be buckled in cover plate on top base on breach, and the projection on cover plate tightly is pressed on the external insulation skin, screen in the middle of cable contacts with shell fragment on shell under the pressure of cover plate, makes shell play the effect of shielding.

Do not need instrument while the utlity model has user's line ball, contact contacts with wire reliably, the advantage that tail end and cable crimp force are large.
