Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a low-voltage wire harness protective sleeve includes an elastic tube 1, plugs 2 disposed at two ends of the elastic tube 1, and a joint 3 movably connected with the plugs 2 at two ends of the elastic tube 1.

Wherein, elasticity body 1 is used for wrapping up the electric wire part of low pressure pencil, connects 3 to be used for cliping the connecting terminal part at low pressure pencil both ends to avoid elasticity body 1 shrink, removal, and then guarantee the stability of protective sheath.

Joint 3 includes the connecting portion that combines with plug 2, carries out the fixed part that blocks to the electric wire port of low pressure pencil, and joint 3 includes movable body 301, including connection chamber 302, inner panel 303 in the movable body 301, connects chamber 302 and matches with plug 2, sets up a plurality of groups in the inner panel 303 and perforates 304. The number, size, and arrangement of the perforations 304 are related to the low voltage harness design requirements.

The connector 3 is made of transparent organic glass material, on one hand, the connector has high hardness, so that the connector has certain hardness and weight to keep the stability of the connector; on the other hand is convenient for observe the inside pencil condition, is favorable to using.

The inner plate 303 and the movable tube body 301 may be formed as an integral structure or may be formed as a combined structure that is detachable from each other.

In the concrete implementation, elasticity body 1 on the low pressure pencil overcoat to extend its both ends, wear out the connecting terminal of each wire from perforating 304 in proper order again, closely combine the connection behind the plug 2 embedding connection chamber 302 again, in the use, connect 3 difficult removal relatively, and then keep holistic stability. The plug 2 and the connection cavity 302 are connected by any detachable connection such as a screw connection or a fitting connection.

The elastic telescopic property of the elastic tube body 1 enables the elastic tube body to be applied to the protection of wire harnesses with different lengths and thicknesses.

In order to make the connection terminal not easily move when penetrating through the through hole 304, the inner wall of the through hole 304 is covered with an elastic pad 305, and the electric wire placed therein is actively clamped by utilizing the elastic telescopic property thereof. The elastic pad 305 is fixed in the inner wall of the through-hole 304 by adhesion or the like.

The elastic pad 305 is made of elastic material such as sponge or rubber, which is easy to replace.

The elastic tube body 1 is provided with a plurality of groups of air holes 4, which is convenient for heat dissipation.

The pipe wall corresponding to the area of the connecting cavity 302 is inclined, and the outer diameter of the pipe wall is gradually reduced from one end close to the plug 2 to the other end far away from the plug, so that the connecting cavity 302 and the plug 2 can be assembled conveniently, the force can be applied more conveniently, and the combination of the connecting cavity 302 and the plug 2 can be more stably facilitated; the outer wall of the pipe corresponding to the area of the connecting cavity 302 is provided with a plurality of circles of threads.
