The method is widely applied to military systems such as aviation, aerospace, national defense and the like, so the quality requirement is quite high. In the wire stripping-free circular connector, a wire is inserted into an opening of a special-shaped piece, the wire is bent in the special-shaped hole, and then a rubber outer layer of the wire is stripped and connected at the bent part of the wire by slicing.
For example, the patent of CN214474494U issued to the publication provides a circular connector structure of wire stripping-free connection, which is to pass the cable through the special-shaped fixing plastic part and pierce the cable with the special-shaped piercing needle, the knife edge cuts the insulation layer of the wire, and the copper core is directly connected with the knife edge to realize conduction. However, when the wire is inserted into the special-shaped fixed plastic part, the wire cannot be well bent in the special-shaped fixed plastic part due to too soft or too thin wire, or the wire cannot be penetrated out of the special-shaped fixed plastic part due to excessive bending of the wire in the special-shaped fixed plastic part, so that the cutting of the insulation layer of the wire by the subsequent special-shaped puncture is affected, and the performance of the connector is further affected.

Each first protrusion 221 on the first cylindrical block 220 is then aligned with one first runner 111, each second protrusion 231 on the second cylindrical block 230 is aligned with one second runner 112, and the first cylindrical block 220 and the second cylindrical block 230 are gradually inserted into the housing 110. The first protrusion 221 is matched with the first chute 111, the first protrusion 221 first comes into the first limit groove, and then the first protrusion 221 comes into the chute, and at this time, the first cylindrical block 220 and the second cylindrical block 230 relatively rotate. The stopper 225 gradually moves from one end of the arc groove 235 to the other end of the arc groove 235, the first cylindrical block 220 is changed from the first state to the second state, at this time, the first transverse groove 223 corresponds to the second transverse groove 233, the first limiting hole 222 and the second limiting hole 232 are positioned at two sides of the first transverse groove 223 and the second transverse groove 233, the first cylindrical block 220 and the second cylindrical block 230 relatively rotate to complete the bending action on the wire, and the problems that the wire stripping-free slice 210 cannot strip the insulating layer of the wire and cannot be connected with the wire due to the fact that the wire is too soft or too thin and cannot bend in the first cylindrical block 220 and the wire is excessively bent in the first cylindrical block 220 are caused, and the cutting of the wire stripping-free slice 210 on the wire is affected are solved.
The relative rotation of the first cylindrical block 220 and the second cylindrical block 230 straightens the portion of the wire to be connected while bending, so that the wire stripping-free slice 210 has consistent cutting effect on both sides of the wire when cutting the wire insulation layer, thereby preventing the phenomenon that the wire stripping-free slice 210 is in virtual connection with one side of the wire due to inconsistent cutting amount of the insulation layer on both sides of the wire.
Then the first bump 221 goes into the second limit groove, the first cylindrical block 220 and the second cylindrical block 230 continue to go deep, the wire stripping-free slice 210 sequentially passes through the first transverse groove 223 and the second transverse groove 233 and is inserted into the bent part of the wire, and the wire stripping-free slice 210 cuts the insulating layer of the wire and then is connected with the copper wire in the wire, so that wire stripping-free connection is completed.
When the first cylindrical block 220 is in contact with the connection pad 250, each of the cylindrical protrusions 240 is inserted into one of the first limiting holes 222, and the cylindrical protrusions 240 block the first limiting holes 222. At this point the lead on the first cylindrical block 220 will be crimped within the first channel. When a tensile force occurs on the wire, the wire is stretched and retracted, and meanwhile, under the action of the wire stripping-free slice 210, the insulation layer on the wire is stripped, but because the wire is bent by the first cylindrical block 220 and the second cylindrical block 230 relatively rotating and the wire is bent by the first cylindrical block 220, the wire is not easily separated from the first cylindrical block 220 by external tensile force, and meanwhile, the stripped insulation layer is accumulated in the first channel, and the wire is not easily pulled to be separated along with the increase of the service time. And then the nut back cover 120 is rotated to connect the nut back cover 120 with the housing 110, thereby completing the installation of the connector, and finally, the connector is inserted into the corresponding plug.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
