To achieve the above object, the technical scheme adopted in the present invention is as follows:

A wire harness fixing device applied to a wire harness connector, including an outer sleeve, plugs are inserted and fixed at both ends of the outer sleeve, and strip grooves are formed on the opposite outer walls of the outer sleeve between the plugs to penetrate the inner wall of the outer sleeve. The T-shaped strut passes through the plugs at both ends of the outer casing and is screwed with lock nuts. The head of the T-shaped strut rests on the plug at one end of the outer casing, and the locking nuts are distributed at the tail end of the T-shaped strut. And against the plug at the other end of the outer casing, the tail end of the T-shaped strut is fixed with a dial; the T-shaped strut inside the outer casing is formed with several through holes; the outer walls at both ends of the outer casing A trapezoidal bracket is fixed on the top, a positioning nut is inserted into the bracket, and the positioning nut is welded and fixed on the bracket.

Preferably, the T-shaped strut is a round rod, the plug is formed with a through hole for the T-shaped strut, and the diameter of the T-shaped strut is smaller than the diameter of the inner wall of the outer casing.

Preferably, the through-holes are linearly and evenly distributed on the T-shaped strut, the diameter of the through-hole is smaller than the groove width of the bar-shaped channel on the outer casing, and the distance between the through-holes at both ends of the T-shaped strut is smaller than that of the bar-shaped channel. The length of the channel.

Preferably, rounded corners are formed at both ends of the through hole on the T-shaped strut.

Preferably, the diameter of the outer wall of the locking nut is larger than that of the outer casing, the diameter of the outer wall of the dial is smaller than that of the outer wall of the locking nut, and there is a gap between the outer dial and the locking nut.

Preferably, the bracket is formed with a bolt through hole matched with the positioning nut, and the lower end surface of the bracket is parallel to the side wall of the bar-shaped channel on the outer sleeve.

The beneficial effect of the present invention is that it proposes a device that can realize fixing and collect redundant wire harnesses on the wire harness connector, which can avoid contact between the wire harnesses and the control board, etc., and can realize the positioning of the wire harnesses on components such as the control board superior.
