In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 10 together, a housing of a harness connector according to the present invention will now be described. The harness connector housing comprises a first barrel 11 (barrel: tubular object with through-going bore; alternatively, in one embodiment, the barrel is a cylinder; specifically, in one embodiment, the axis of the cylinder is a straight line), a second barrel 12, and a third barrel 13; one end of the second cylinder 12 is in threaded connection with the first cylinder 11, the other end of the second cylinder 12 is in threaded connection with the third cylinder 13, and the first cylinder 11, the second cylinder 12 and the third cylinder 13 are sequentially communicated to form a cable channel 15; a first pulling structure 111 matched with a wrench is arranged on the outer surface of the first barrel 11, and a second pulling structure 121 matched with the wrench is arranged on the outer surface of the second barrel 12; the third cylinder 13 is provided with a wire bundling mechanism therein.

Thus, the first cylinder 11 is in threaded connection with the second cylinder 12, and the first cylinder 11 can be installed/separated by rotating the first cylinder 11 through the first pulling structure 111 by using a wrench; the second cylinder 12 is in threaded connection with the third cylinder 13, and the second cylinder 12 can be installed/separated by rotating the second cylinder 12 through the second pulling structure 121 by using a wrench; the first barrel 11, the second barrel 12 and the third barrel 13 are communicated in sequence to form a cable channel 15 for laying wires; the first barrel 11, the second barrel 12 and the third barrel 13 are very convenient to separate, and lead wires are convenient to arrange; the wire bundling mechanism is arranged in the third cylinder 13, the wire bundling mechanism is not easily interfered by external environment under the protection of the third cylinder 13, and the wire bundling mechanism can be installed or disassembled after the third cylinder 13 is detached from the second cylinder 12, so that the wires can be bundled or scattered conveniently.

Further, referring to fig. 1 to 10, as an embodiment of the housing of the wire harness connector provided by the present invention, the wire harness mechanism includes an elastic cylinder 14 disposed in the third cylinder 13 and a stop wall 131 disposed on an inner wall of the third cylinder 13; the elastic cylinder 14 extends along the axial direction of the second cylinder 12, and the elastic cylinder 14 is clamped between the stop wall 131 and the second cylinder 12; the stopper wall 131 is curved toward the axis of the second cylinder 12 in a direction extending along the axis of the second cylinder 12 and away from the second cylinder 12. Thus, the lead sequentially passes through the second cylinder 12, the elastic cylinder 14 and the third cylinder 13; the inner wall of the third cylinder 13 is provided with a stop wall 131, the elastic cylinder 14 is clamped between the stop wall 131 of the third cylinder 13 and the second cylinder 12, and when the third cylinder 13 is locked, the stop wall 131 approaches the second cylinder 12 along with the third cylinder 13; since the stopper wall 131 is curved toward the axis of the second cylinder 12 in the direction extending along the axis of the second cylinder 12 and away from the second cylinder 12, that is, the portion of the stopper wall 131 farther from the second cylinder 12 is closer to the axis of the second cylinder 12; when the stopping wall 131 is close to the second cylinder 12, the stopping wall 131 presses the elastic cylinder 14 toward the axial direction of the second cylinder 12, so that the wires passing through the elastic cylinder 14 are contacted more closely, the wires passing through the elastic cylinder 14 are bundled, and the loose condition of the wires is reduced.

Alternatively, in one embodiment, the second cylinder 12 and the third cylinder 13 are coaxially disposed.

Further, referring to fig. 1 to 10, as an embodiment of the harness connector housing provided by the present invention, a side surface of the elastic cylinder 14 near one end of the stop wall 131 is bent toward the axis of the second cylinder 12 in a direction extending along the axis of the second cylinder 12 and away from the second cylinder 12. In this way, since the surface of the elastic cylinder 14 facing the stopper wall 131 is curved toward the axis of the second cylinder 12, the stopper wall 131 more easily presses the elastic cylinder 14 toward the axis of the second cylinder 12 when the third cylinder 13 is locked (the stopper wall 131 is close to the second cylinder 12).

Further, referring to fig. 1 to 10, as an embodiment of the housing of the harness connector provided by the present invention, an insertion portion 142 is disposed at one end of the elastic cylinder 14 and inserted into the second cylinder 12, and the insertion portion 142 has pipe holes respectively communicating with the second cylinder 12 and the elastic cylinder 14. Thus, the lead wires enter the elastic cylinder 14 from the second cylinder 12 through the pipe holes; the elastic cylinder 14 is clamped in the second cylinder 12 through the inserting portion 142, so that firmness between the second cylinder 12 and the elastic cylinder 14 is improved, and the situation that the tightness of a wire penetrating through the elastic cylinder 14 is influenced after the elastic cylinder 14 is vibrated is reduced.

Further, referring to fig. 1 to 10, as an embodiment of the housing of the harness connector provided by the present invention, an outer wall of the inserting portion 142 is attached to an inner wall of the second cylinder 12. Therefore, the tightness between the elastic cylinder 14 and the second cylinder 12 is better, and the tightness of the wire penetrating through the elastic cylinder 14 due to the shaking influence of the elastic cylinder 14 is reduced.

Further, referring to fig. 1 to 10, as an embodiment of the housing of the harness connector provided by the present invention, the outer wall of the inserting portion 142 is a cylindrical surface coaxial with the second cylinder 12.

Optionally, in one embodiment, the shielded wire is a copper/aluminum wire.

Wherein, the shielding effect of the metal ring can be referred to a Faraday cage.

Optionally, in one embodiment, the metal loop is a spring loop. In this way, the spring ring is easy to adjust its length/curved shape.

Optionally, in one embodiment, the spring coil is a coil spring. Thus, the coil spring is easy to produce and bend.

Optionally, in one embodiment, the spring ring is a unitary piece of stainless steel. Thus, the stainless steel is corrosion resistant, and in addition, the stainless steel material has good diamagnetism.

Further, referring to fig. 1 to 10, as an embodiment of the housing of the harness connector provided by the present invention, a rotation direction of the first pulling structure 111 is perpendicular to an extending direction of the cable channel 15, and/or a rotation direction of the second pulling structure 121 is perpendicular to the extending direction of the cable channel 15. Thus, when the user engages the first pulling structure 111 through the wrench and rotates the first barrel 11, the wires in the cable channel 15 are not easily interfered; the user can engage the second pulling structure 121 with a wrench and rotate the second barrel 12 without disturbing the wires in the cable channel 15.

Further, referring to fig. 1 to 10, as an embodiment of the housing of the wire harness connector provided by the present invention, a sealing ring 2 is disposed in the elastic cylinder 14 for being sleeved on the wire.
