Abstract

The utility model relates to an eight-core bearing watertight electric connector which comprises a tail cap, a plug, a socket, a bearing structure and a fixing nut. The bearing structure is mounted at the tail end of the plug and socket via the tail cap, the plug is mounted on the socket via the fixing nut, the bearing structure comprises a fixing ring, a gasket, an O-shaped loop, a spindle body, a tensile mechanism housing and a parallel cable sheath cap, aramid fiber is fixed with the taper-shaped inner wall structure of the tensile mechanism housing via the spindle body, and residual aramid fiber, the O-shaped loop, the gasket and the spindle body are fixed in the tensile mechanism housing via the fixing ring. According to the utility model, a small-size cable can resist relatively large instant tension of surge, wherein a bearing aramid fiber core of the small-size cable and a cable sheath are ingeniously connected with the eight-core bearing watertight electric connector to ensure that the cable is not fractured under a 105kg instant axial force; and the eight-core bearing watertight electric connector also has the advantages of convenience in installation and strong reliability.

Description

A kind of eight core load-bearing water-tight electrical connectors

Technical field

The utility model relates to a kind of load carrier of the small size cable of ocean stereoscopic monitoring equipment.

Background technology

Ocean stereoscopic monitoring equipment is due to the restriction of size, and the cable size in lower storehouse is only 5mm, in order to resist the larger instantaneous pulling force of surge, need to adopt a kind of reliable load-bearing water-tight electrical connector.

Utility model content

The purpose of this utility model is in order to realize small size cable, in junction, to resist the larger instantaneous pulling force of surge, adopts following technical proposals to realize:

A kind of eight core load-bearing water-tight electrical connectors, it is characterized in that: eight described core load-bearing water-tight electrical connectors comprise tail cap, plug, socket, load-carrying members, hold-doun nut, described load-carrying members are arranged on respectively the rear end of plug and socket by tail cap, plug is arranged on socket by hold-doun nut; Described load-carrying members comprise retainer ring, packing ring, O type circle, spindle, stretch-proof organization shell, cable cover(ing) cap, aramid fiber is fixed by the conical inboard wall structure of spindle and stretch-proof organization shell, residue aramid fiber, O type circle, packing ring and spindle are fixed in stretch-proof organization shell by retainer ring, and cable cover(ing) is fixed on stretch-proof organization shell front end by clamping cables sheath cap; Eight core wires and eight core contact pin insulator components weldings, eight core contact pin insulator assemblies are separately fixed in plug and socket according to alignment pin, the O type ring recess of eight core jack insulator assembly outsides of plug packs O type circle into, and evenly coat seal grease, according to alignment pin, align, eight core contact pin insulator assemblies of socket insert eight core jack insulator assemblies of plug, and the O type ring recess of plug seals with the interior wall construction of socket simultaneously.

The utlity model has following advantage:

Under the prerequisite of small size cable, by cable load-bearing aramid fiber core, cable cover(ing), be connected cleverly with eight core load-bearing water-tight electrical connectors, can guarantee not rupture under the instantaneous responsive to axial force of 105kg, the utility model also has simple installation, the advantage that reliability is strong simultaneously.

accompanying drawing explanation:

Fig. 1 is eight core load-bearing water-tight electrical connector structure charts;

Fig. 2 is eight core load-bearing water-tight electrical connector load-carrying members profiles;

Description of reference numerals: tail cap 1, plug 2, socket 3, load-carrying members 4, hold-doun nut 5, retainer ring 6, packing ring 7, O type circle 8, spindle 9, stretch-proof organization shell 10, cable cover(ing) cap 11, cable 12, eight core wires 13.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described in detail:

As shown in Figure 1, with tail cap 1, connector load-carrying members that install 4 and plug 2, socket 3 shells are fastening, with hold-doun nut 5, plug 2 is fixing with socket 3, and with two stop screws, the position of hold-doun nut 5 is fixed.

As shown in Figure 2, stressed for fear of eight core wires 13, first aramid fiber core and eight core wires 13 are separated, eight core wires 13 pass from spindle 9, spindle 9 is adjacent to cable cover(ing) cap 11 edges, aramid fiber core is evenly distributed on spindle 9 surroundings, aramid fiber is realized under the effect of the force of sliding friction of the conical internal cavity of spindle 9 conical outer surfaces and stretch-proof organization shell 10 fixing, and the conical inboard wall structure of eight lobe stretch-proof organization shells 10 is compressed to spindle 9; Residue aramid fiber is evenly filled in to spindle 9 inner chambers, and the upper O type circle 8 of pad and packing ring 7, tighten stretch-proof organization shell 10 with retainer ring 6 successively, compresses aramid fiber and spindle 9 simultaneously, prevents that aramid fiber core from moving when load-bearing; Cable 12 is advanced to stretch-proof organization shells 10, and with spindle 9 close contacts, by clamping cables sheath cap 11, be fixed on stretch-proof organization shell 10 front ends, realize the fixing of cable cover(ing); By eight core wires 13 and eight core contact pin insulator components weldings, eight core contact pin insulator assemblies are separately fixed in plug 2 and socket 3 according to alignment pin, O type ring recess in eight core jack insulator assembly outsides of plug 2 packs O type circle 8 into, and evenly coat seal grease, according to alignment pin, align, eight core contact pin insulator assemblies of socket 3 are inserted to eight core jack insulator assemblies of plug 2, the O type ring recess of plug 2 seals with the interior wall construction of socket 3 simultaneously.

To description of the present utility model, do not have restricted above; if those of ordinary skill in the art is enlightened by it; in the situation that does not depart from the protection of the utility model claim, make other malformation of the present utility model and execution mode, all belong to protection range of the present utility model.
