A part of the cable which is provided with a conducting wire joint is arranged in the protective sleeve; the cable pressing wires are arranged on both ends of the cable and are arranged on both ends of the protective sleeve through a locking screw and the fastening ring; the spacer and the sealing ring are arranged in the protective sleeve in an interphase mode and are sheathed on the outer side of the cable in the position of the conducting wire joint; the filler is arranged between the spacer and the sealing ring. The utility model has the advantages of simple connection, convenient operation and reliable contact; reliable water sealed connection of the cable among a measuring instrument, an underwater sensor and a detecting probe can be ensured.

Description

A kind of cable watertight jockey

Technical field

The utility model belongs to wired electric energy and signal of telecommunication transmission technique field under water.It specifically is a kind of cable watertight jockey that is used for the electrical connection transmission of subaqueous survey instrument, transducer and detection probe.

Background technology

In ocean expedition, in the hydrology of river, river, lake, pool, the geologic survey, what need that observation by measuring instrument obtain the hydrology, geology has related parameter and a data, so that control and protection water environment and be installed on job facilities in the water.In the ordinary course of things, be in time to obtain measurement data, need be connected with cable between measurement and control instrument and underwater sensor and the detection probe.Operation in the open air, especially pool (offshore platform, boats and ships etc.), field condition is poor, some environment wiring welding difficulty.Again because of a lot of situations be cable already cloth be put in the working site, and cable lays and installs and uses longly at interval with instrument, gives the termination easy damaged of putting, and now connects so majority is existing usefulness.At the scene in the condition of contact rigorous environment, special procure to operation sequence require convenient, method of attachment is simple, solid and reliable, the cable watertight jockey that watertightness is good.Existing interconnection technique and method mainly contain following several: directly twist and connect or weld at the cable joint place, twines band seal nipple position afterwards again, but the low watertightness performance of their intensity is poor.Also have sealing plug to place the rigidity adapter sleeve, its volume is relatively just big, material and processing charges height, very uneconomical.And with the difference of environment for use, watertightness and reliability decay are fast, occur (as potential safety hazards such as electric leakage, water inlet, fractures) problem easily when long-term and abominable sea situation, even the accidents caused enormous economic loss that causes.Have direct insertionly abroad, but need the mould one-shot forming, mould is made complicated, involves great expense, and general limitation is big, several thousand yuan of banjo prices.

The utility model content

In order to have solved above problem, the purpose of this utility model provide a kind of connect simple, easy to operate, contact is reliable, can guarantee that cable has the cable watertight jockey that reliable watertight is connected between measuring instrument and underwater sensor and the detection probe.

The technical solution of the utility model is: comprise the cable silk pressing, cable tightens up ring, sheath, sealing ring, pad, filler; The part that has terminal on the described cable is installed in the sheath, and the cable silk pressing is installed the cable two ends, again by lock screw, tighten up the two ends that ring is installed in sheath; Described pad, sealing ring is alternate is arranged in the sheath, is set in the outside of terminal place cable; Between pad and sealing ring, be provided with filler;

Described tighten up the ring be two semi-loops; Pad, sealing ring are a plurality of; Filler can adopt vacuseal grease.

The utlity model has following advantage:

1. watertightness is good, circuit connects reliable owing to adopt multiple-sealed measure (referring to embodiment, every end has 4 layers of pad and 3 layers of sealing ring).

2. the device two ends adopt in design that two semi-rings form tightens up ring, lock screw, realize to cable reliable grip, fix, dwindled physical dimension greatly.

3. two cables are connected firmly, and the signal conductive performance is good.

4. part is few simple in structure, easily processing, and cost is low, and versatility is good; Method of operation is simple, need not train especially.

5. purposes is wide, the economic benefit height.

Embodiment

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Shown in Fig. 1～4, the utility model is by cable silk pressing 1, cable 2, tighten up ring 3, lock screw 4, sheath 5, lead 6, sealing ring 7, pad 8, filler 9 is formed, and wherein: the part that has lead 6 joints on the cable 2 is installed in the sheath 5, cable silk pressing 1 is installed cable 2 two ends, again by lock screw 4, tighten up the two ends that ring 3 is installed in sheath 5; Described pad 8, sealing ring 7 alternate being arranged in the sheath 5 are set in the outside of lead (6) joint cable 2, and are compressed by cable silk pressing 1, guarantee the joint watertight of two cables; Between pad (8) and sealing ring (7), be provided with filler (9).

Described pad 8, sealing ring 7 are a plurality of, and present embodiment adopts 8,6 sealing rings 7 of 8 pads.Described filler 9 can adopt vacuseal grease.

Described cable silk pressing 1 and tighten up ring 3 all to be two be a cover, 1 tightens up ring 3 and is made up of two semi-rings, and it is a cover that lock screw 4 is 8.Device two ends mounting means is identical, so the joint of two cables is not pullled by external force, promptly is connected firmly.

At first carry out following operation in use:

1. earlier left and right two cable silk pressings 1 are installed in the two ends of cable 2.

2. the cable two ends of pad 8 and sealing ring 7 being packed in order, and with cable silk pressing 1, pad 8 and sealing ring 7 push away suitable distance to the cable rear portion, wherein the left side from sheath 5 of a cable 2 penetrates again, pull out from the right, and then the lead 6 in the cable 2 that will connect connects, and will carry out insulated enclosure between each lead and handle.

3. the junction of two cables 2 is pulled to the middle part of sheath 5, again pad 8 and sealing ring 7 are pushed sheath 5 sealed at both ends storehouses (sheath 5 inner chambers successively, the two ends that hold two cables 2, be lead 6 connecting portions) in, the an amount of filler 9 of packing into simultaneously, between sheath 5 and cable 2, then cable silk pressing 1 is screwed into sheath 5 two ends, compress gasket 8 and sealing ring 7.

4. will tighten up ring 3 (two semi-rings form) and be respectively charged in the cable silk pressing 1, and with fixing and locking screw 4 cable 2 be tightened up and get final product.
