A kind of cable connector

Technical field

The utility model belongs to the subaqueous survey technical field.It specifically is a kind of cable connector that is used for subaqueous survey instrument, transducer and detection probe and transmission cable.

Background technology

In ocean expedition, in the hydrology of river, river, lake, pool, the geologic survey, need to obtain the related parameter that has of the hydrology, geology, so that the job facilities in control and the protection water environment by the observation of measuring instrument.In the ordinary course of things, need between measurement and control instrument and underwater sensor and the detection probe be connected with cable.Operation in the open air, (offshore platform, boats and ships etc.) especially waterborne, field condition is poor, and some environment wiring does not allow welding.Such as, a lot of situations are that cable discharges already in the working site, multiple reason (install and use oversizely at interval as cable dispensing and instrument, idle termination is easy damaged more, of long duration be difficult to guarantee handy) is not established termination.So, at the scene in the condition of contact rigorous environment, special procure to operation sequence require not only convenient, but also reliably, also want the good jockey of watertight.Existing interconnection technique and method (being generally welding) can not satisfy this three conditions simultaneously.

The utility model content

In order to have solved above problem, the purpose of this utility model provides a kind of need not weld, can guarantee measuring instrument and the reliable cable connecting arrangement that is connected of the cable between underwater sensor and the detection probe.

The technical solution of the utility model is: comprise connector socket and connection plug and cable; It is characterized in that: also comprise pressing plate, cable is wired, and left fittings body connects silk, binding clip, the right connector body, pad, clamping cap, sealing ring, wherein: a left fittings body is installed in the described connector socket outside that links to each other with cable, and a right connector body is installed in the connection plug that links to each other with the cable outside, and connector socket and connection plug snap together by clamping cap; Cable is wired to have external screw thread, is threaded with the left fittings body with internal thread, and the wired front end of cable is semicircle, is installed together with semicircle pressing plate; The right connector body has internal thread, is threaded with cable is wired, and the wired front end of cable is semicircle, is installed together with semicircle pressing plate; Connect silk and be installed in respectively on connector socket, the connection plug, be threaded with left fittings body or right connector body;

Between left fittings body, right connector body and cable, add a plurality of pads, in the wired inner termination place of cable; Establish multiple-sealed circle at connector socket and connection plug junction; Described pad is selected metal and two kinds of materials of rubber for use, alternate setting, and wherein: the metal material pad is 2～5 roads, the elastomeric material pad is 1～4 road; Described sealing ring road number can be 3～5; The terminals place of the pin holes of the connection plug that is connected with cable, the jack of connector socket is provided with binding clip; The number of described binding clip is general to adopt 2～5.

The utlity model has following advantage:

1. watertightness is good, circuit connects reliable owing to adopt multiple-sealed measure (as 7 layers of pad and 3 layers of sealing ring).

2. need not weld,, avoid the adverse effect of bringing by welding (as: staff will equip the electric welding apparatus, and does not allow welding etc. on the oil platform sometimes) with before assembling.

3. easy to operate, operation sequence is simple, need not train especially.
