Abstract

The utility model relates to a modified awl stopper formula electric connector, including plug, socket, the contact surface in socket (hole) is conical to the axial of plug or socket is equipped with elastic element and plays the two retainer rings of axial positioning effect. The tail part in the plug body is provided with the wire pressing device, and the cable clamping device has the advantages that the cable is clamped by the wire pressing device, so that the joints of the plug and the wiring terminal and the cable are not affected by vibration and shaking generated by train operation and braking, and the train operation safety is ensured. The double retainer rings formed by overlapping the two retainer rings are arranged at the positions of the plug and the socket (hole) for installing the retainer rings, so that the safety performance of the plug and socket is greatly improved.

Description

A kind of improved cone plug type electric connector

The utility model relates to a kind of improved cone plug type electric connector.Belong to technical field of electric connectors.

Prior art, include plug, socket, plug, the contact-making surface of socket (hole) is conical, axially being equipped with of its plug or socket guarantees to connect the reliable flexible member (ZL92229049.0) that contacts, it is as the electric connector on the train, in its practice process, finding still has following weak point: 1. between the electric connector of train adjacent compartment, owing to connect the one group very heavy big cable of having hung cross-over connection, in the process of train operation and braking, cable can produce sizable rocking along with train, makes that the junction between cable and terminal and terminal and the plug is caused loosening and the generation loose contact easily, temperature rise is increased, and influences the safe operation of train.2. the plug of electric connector or socket (hole), it is spacing with single back-up ring that its axial extended position of back is installed, because plug or socket (hole) are in work and plug process, back-up ring often is subjected to the effect of inhomogeneous power, fracture easily, thereby the danger that causes plug or socket (hole) to locate, promptly charged plug may be gone here and there and be touched protecting cover and short circuit.Also can bring difficulty in addition to plug.

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of improved cone plug type electric connector, makes that it more becomes reliably, safety.

Technical solution of the present utility model:

Include plug, socket, the contact-making surface of plug, socket (hole) is conical, and plug or socket the flexible member that guarantees the reliable contact of connector axially is housed, the afterbody in plug body is provided with cord grip, plug or socket axially on two back-up rings of axial location effect have been housed.

Cord grip is made up of pressing plate, line ball seat and screw, and three pressuring line grooves are arranged on the pressing plate, and three support wire casings are arranged on the line ball seat, and the line ball seat is arranged in the plug body, and pressing plate and line ball seat are to flexibly connect by screw.

Two back-up rings are to be formed by stacking by two back-up rings.

Advantage of the present utility model:

1, in plug body, increases the cable cord grip, made the junction of plug and binding post and terminal and cable, no longer be subjected to train operation and brake vibration that is produced and the influence of rocking, further guaranteed the safety of the permanent operation of train.

2, install on the position of back-up ring at plug or socket (hole), adopt the two back-up rings that are formed by stacking by two back-up rings, make, reduce rate of failure, guarantee safety if there is a back-up ring fracture to also have a back-up ring to work.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the sectional structure schematic diagram of cord grip;

Fig. 3 is two back-up ring structural representations;

Among the figure 1 is plug, the 2nd, terminal, the 3rd, and cable, the 4th, cord grip, the 5th, plug body, the 6th, pressing plate, the 7th, pressuring line groove, the 8th, screw, the 9th, line ball seat, the 10th, support wire casing, the 11st, socket (hole), 12 and 13 is back-up rings.

Further describe technical solution of the present utility model below in conjunction with accompanying drawing:

Cord grip 4 is provided in a side of the afterbody in the plug body 5, and it is made up of pressing plate 5, screw 8 and line ball seat 9, and three pressuring line grooves 7 are arranged on the pressing plate, and three support wire casings 10 are arranged on the line ball seat, and cable 3 is installed in the support wire casing, is compressed by screw by the pressuring line groove on the pressing plate.Because cable is by the fixing chucking of cord grip, can be not loosening in train travelling process because of vibrating, rock the junction generation that causes cable and terminal 2 and terminal and plug 1, guaranteed that train safe travels.

Two back-up rings that socket (hole) axial location is used are formed by stacking by two back-up

rings

12 and 13, make if when having a back-up ring to damage, also have a back-up ring can play position-limiting action, string moves to prevent socket (hole) to take place arbitrarily, guarantees unlikely touching short circuit of charged socket (electric arcing, blast) and operating difficulties.

Claims

1, a kind of improved cone plug type electric connector, comprise plug, socket, the contact-making surface of plug, socket is conical, and axially being equipped with of plug or socket guarantees the reliable flexible member that contacts of connector, it is characterized in that the afterbody in plug body is provided with cord grip, plug or socket axially on two back-up rings of axial location effect have been housed.

2, improved cone plug type electric connector according to claim 1 is characterized in that cord grip is made up of pressing plate, line ball seat and screw, and three pressuring line grooves are arranged on the pressing plate, and three support wire casings are arranged on the line ball seat, and pressing plate and line ball seat are to flexibly connect by screw.

3, improved cone plug type electric connector according to claim 1 is characterized in that two back-up rings are formed by stacking by two back-up rings.
