Description

Electric connector

Technical field

The utility model is relevant a kind of electric connector, especially refers to a kind of electric connector that reduces assembling procedure that has.

Background technology

By electric connector finding is arranged in electric equipment products, its main application is the conduction of power supply or signal more, and therefore, electric connector has been widely used for the connection of information products, and is indispensable member.

In fact, the utilization of electric connector not only is aforesaid electric equipment products, and it also is widely used in the Circuits System of vapour, locomotive, with the binding as circuit.And be that the contact terminal of guaranteeing electric connector inside can firmly locate and lock.

Extremely shown in Figure 3 like Fig. 1; Be the profile after three-dimensional exploded view, assembling back stereogram and the assembling of known electric connector; This electric connector is by a body 10, one terminal position assurance member (terminal position assurance, TPA) 30 compositions of 20 and one retainer ring seat.Wherein, this body 10 is class's shape body, and is as shown in Figure 3, and these body 10 inner radial integrally formed one are offered the middle partition 101 of a plurality of pin-and-holes 102, makes to form a location division 103 and a junction surface 104 respectively in middle partition 101 both sides.And these junction surface 101 end faces are offered the catching groove 105 that is connected, and these catching groove 105 back distal process are established a retaining tenon 106.

This terminal position assurance member 20 is axially offered the terminal groove 201 of a plurality of alignment pin holes 102, and each terminal groove 201 opening rear extension one supplies the elasticity locating detent 202 of pawl groove 601 snaps into position of inserting terminal 60.During assembling, after these terminal position assurance member 20 peripheries are given a glue, and insert, and after waiting for a period of time quietly, this terminal position assurance member 20 is glued in the location division 103 by location division 103 openings of body 10; Then, in addition a waterproof pad 40 is sheathed on location division 103 openings, a plurality of wire holes 401 that this waterproof pad 40 is axially offered are relative with terminal groove 201.Inserting terminal 60 is then inserted by the wire hole 401 of waterproof pad 40; And be fixedly arranged on location in the terminal groove 201; Make the latch 602 of an end pass through the pin-and-hole 102 of middle partition 101, and stretch in the junction surface 104 that the lead 603 of inserting terminal 60 other ends is then stretched out by wire hole 401.

And this retainer ring seat 30 is a size and appearance corresponding to the inner ring body in junction surface 104; This retainer ring seat 30 is inserted by junction surface 104 openings of body 10; The elasticity button hook 301 of these retainer ring seat 30 end face projections is buckled in the catching groove 105, and with the retaining tenon 106 be the backstop that elasticity button hook 301 is deviate from, this retainer ring seat 30 is buckled in the junction surface 104; So that supply a complementary electrical connector (known device; Illustrate) insert in this retainer ring seat 30, make a plurality of contact terminals of this complementary electrical connector supply latch 602 to peg graft, be electrically connected with formation.

Wherein, for provide the complementary electrical connector and and the waterproof effect of 10 of bodies,

partition

101 and 30 sheathed waterproof plastic rings 50 of retainer ring seat in this.

The remarkable defective of aforementioned electric connector is that this terminal position assurance member 20 must be cemented in the tubulose location division 103 of body 10 with the gummed mode, except that waiting for the dry time, and also labor man-hour and manpower, so that production capacity can't promote.Especially, when the utility model electric connector and complementary electrical connector are pulled out when separating, those inserting terminals 60 are because of the effect of reaction force, and pulling terminal position assurance member 20 toward location divisions 103 openings deviate from, and then cause the damage of electric connector, and demand urgently improving.
