Problems solved by technology

When the testers seal a bundle of watertight wires containing several wires, because the wires will be intertwined and the silicone rubber will bond to each other, resulting in uneven thickness of the coated silicone rubber, and even air holes or gaps, the sealing effect is poor. Poor, sealing workload also increases
In addition, during the field test, the butt joints that are in the sealing process (703 silicone rubber has not been fully cured) are often damaged by factors such as sunshine, rain, oil stains, dust, etc. due to no corresponding protection measures, which are easy to bring damage to the normal test. adverse consequences
In addition, with the increase of structural pressure tests, the problem of watertight wire butt joint sealing is also becoming more and more prominent

Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , figure 2 As shown, a wire fixing protection device for watertight wire butt joint sealing includes a round rod 1, at least one large wire fixing disk 2 and a small wire fixing disk 3 are fixed on the round rod 1 through a fastening nut 4, and on the round rod 1. A protective device is also provided on the outer periphery of the large thread-fixing reel 2 and the small thread-fixing reel 3. The protective device is composed of a pair of protective clips 6 movably connected by a rotating shaft 7, and a spring 8 is sleeved on the outer periphery of the rotating shaft 7. Such as figure 1 , figure 2 and image 3 As shown, the protective clip 6 is a semicircular cylinder with an inner cavity, and a pair of protective clips 6 form a circular cylinder when closed, and a plurality of drying holes are opened on the up...

Abstract

The present invention relates to a fixed-line protection device for watertight wire connection sealing. The device comprises a round rod. At least one large fixed-line disk and small fixed-line disk are fixed on the round rod through tightening nuts. The periphery of the round rod, the large fixed-line disk and the small fixed-line disk is also provided with a protection device which is formed by the movable connection of a pair of protection clamps through a rotation shaft. The device has the advantages of simple structure and easy operation, watertight wires can be uniformly separated and fixed by using the large fixed-line disk and the small fixed-line disk, the sealing operation by test personnel is facilitated, by using the protection device, a connector in the sealing process is prevented from the damage of an external environment (sunshine, rain, grease, and dust), the adhesion quality and sealing effect of the silicon rubber on the connector are greatly improved, and the workload is reduced significantly.

Description

technical field [0001] The invention relates to the field of underwater sealing test and testing, in particular to a wire-fixing protection device for butt sealing of watertight electric wires. Background technique [0002] At present, for the strain test of the hydrostatic pressure test of the underwater pressure-resistant structure, it is necessary to use electric wires to transmit the resistance signal of the strain gauge. The electric wires in this test are divided into watertight electric wires and non-watertight electric wires. When the watertight electric wire is connected with the watertight connector, the sealing problem of the connection between the electric wires is very critical. The current method used is to butt the wires with solder, and then apply multiple layers of 703 silicone rubber to seal. The higher the test water pressure, the more 703 silicone rubber coatings are required, and the higher the coating quality requirements are. When the testers seal ...
