Abstract

A self-locking type electric connector comprises a plug and a socket, wherein, the plug consists of a contact pin component, a contact pin insulator, a plug casing and a connecting mechanism consisting of a connecting sleeve, and the socket mainly comprises a jack component, a jack insulator and a socket casing. The utility model is characterized in that the self-locking electric connector further comprises a locking mechanism consisting of a tooth rack fixedly connected or integrated with the outer circumferential wall of the plug casing, and provided with evenly-distributed teeth, a pawl with the waist part being movably connected with the connecting sleeve through a screw, and a reset button; a hole is formed on the connecting sleeve in the position corresponding to the reset button; one end of the reset button penetrates the hole, and the other end thereof is fixedly connected with or integrated with one end of the paw; and a claw capable of being engaged with teeth is arranged at the other end of the pawl. Due to the adoption of the utility model, the pawl can be tightly engaged with the tooth rack when the plug is screwed with the socket in place, and the plug can be tightly locked with the socket, so that the operating requirements of the stable and reliable connection of the electric connector on a high-speed operation carrier are met.

Description

The self-locking electric connector

Technical field

The utility model belongs to the annex of electric connector, relates to a kind of self-locking electric connector, is the improvement of prior art, is applicable to that various electric connectors adopt, in the electric connector that is specially adapted to realize on the high-speed cruising carrier being electrically connected.

Background technology

Electric connector is made up of plug and socket, comprises housing, insulator, contact (being made of contact pin assembly and plugging hole component) three big elementary cells; Plug mainly is made of contact pin assembly, contact pin insulator, plug casing and a bindiny mechanism that comprises adapter sleeve; Socket mainly is made of plugging hole component, jack insulator and Socket casing; In the prior art, electric connector is applied on the carrier of general running status and static state mostly, and plug is threaded or the bayonet socket connection with socket adopt on being connected more, does not generally have retaining mechanism or device.Development along with society, the speed-raising of railway traffic and urban track traffic, electric connector is on the carrier of the high-speed cruising that is connected into row more than two and two, as: keep straight at a high speed (high acceleration), tempo turn (big centrifugal force), high speed are crawled under the occasions such as (centrifugal force change fast), employing is threaded or bayonet socket connects, poor seismic behavior easily produces loosening or obscission, is difficult to satisfy the instructions for use that is electrically connected on the high-speed cruising carrier.

Summary of the invention

The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, by setting up a retaining mechanism, thereby provides a kind of self-locking electric connector that can satisfy the reliable instructions for use that connects on the high-speed cruising carrier.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-locking electric connector, form by plug and socket; Plug mainly is made of contact pin assembly, contact pin insulator, plug casing and a bindiny mechanism that comprises adapter sleeve; Socket mainly is made of plugging hole component, jack insulator and Socket casing; It is characterized in that: also comprise a retaining mechanism, this retaining mechanism by: fixedly connected with described plug casing (1a) outer circle wall or be connected as a single entity (global formation), be evenly equipped with the tooth bar (4) of one group of tooth (4a), waist is by the ratchet (5) of screw or rivet (7) and described adapter sleeve (3) flexible connection, and reset button (6) constitutes; Go up porose (8) with the adapter sleeve (3) of reset button (6) correspondence position, one end of reset button (6) passes hole (8), the other end is fixedlyed connected or be connected as a single entity (global formation) with an end of ratchet (5), the other end of ratchet (5) have can with the pawl (5a) of tooth (4a) engagement.

In the technical solution of the utility model: described tooth bar (4) is the 1/6-1/3 of the excircle girth of plug casing (1a) along the setting of excircle direction and the length of plug casing (1a) preferably.

Compared with prior art, the utlity model has following characteristics and beneficial effect:

(1) adopts the utility model, when electrical connector plug and socket screw when putting in place, ratchet and tooth bar tight engagement, make the locking of plug and socket, can guarantee two with the carrier that becomes to be connected into row more than two under any running status, be electrically connected reliable and stable, can satisfy the reliable instructions for use that connects of on high-speed cruising carrier electric connector;

(2) simple in structure, produce easy to install, practical, be specially adapted to appliance chamber on the high-speed cruising carrier reliable, stable, be electrically connected fast.

Embodiment

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Embodiment 1: referring to each accompanying drawing.

A kind of self-locking electric connector is made up of plug 1, socket 2 and a retaining mechanism; Plug 1 mainly is made of contact pin assembly 1b, contact pin insulator 9, plug casing 1a (contact pin assembly 1b is loaded in the contact pin insulator 9, reinstalls in the plug casing 1a same prior art) and a bindiny mechanism that comprises adapter sleeve 3; Socket 2 mainly constitutes (plugging hole component 2b is loaded in the jack insulator 10, is loaded in the Socket casing 2a same prior art again) by plugging hole component 2b, jack insulator 10 and Socket casing 2a; Retaining mechanism by: be connected as a single entity (global formation), be evenly equipped with the tooth bar 4 of one group of tooth 4a with described plug casing 1a outer circle wall, the ratchet 5 that waist flexibly connects by screw or rivet 7 and described adapter sleeve 3, and reset button 6 constitutes; With porose 8 on the adapter sleeve 3 of reset button 6 correspondence positions, the end that an end of reset button 6 passes hole 8, the other end and ratchet 5 is connected as a single entity (global formation), the other end of ratchet 5 have can with the pawl 5a of tooth 4a engagement; 1/4 of the excircle girth that described tooth bar 4 is plug casing 1a along setting of excircle direction and the length of plug casing 1a.

During use:

The recessed key of the protruding key alignment socket housing 2a of plug casing 1a pushed hard insert, contact pin assembly 1b promptly plugs together (same prior art) with plugging hole component 2b; Retaining mechanism rotation on the plug 1 is connected with socket 2;
