Abstract

The utility model belongs to an electrical signal connector, in particular to a connector positioning retainer ring on the connector. The utility model provides the technical scheme as follows: an axial opening gap is formed on the wall of a retainer ring; a plurality of clamping jaws are arranged on the wall of the retainer ring; a plurality of fins with upper edges not being truncated are punched on the wall of the retainer ring and bent outwards along the upper edges thereof to form clamping jaws, or a plurality of fins with bottom edges not being truncated are punched on the wall of the retainer ring, and bent outwards along the bottom edges thereof to form clamping jaws; and each clamping jaw has a rectangular shape with the area being smaller than that of a punching hole. The utility model has the advantages that the retainer ring adopts an opening cylinder which can be conveniently mounted in a groove in the middle of the connector; the clamping jaws of the retainer ring are in fastening fit with the upper benches of an insulator, so as to enable the connector to be fixed in the insulator; and the connector can be conveniently taken out through a pick-off device. The retainer ring is shaped through punching and enhanced in elasticity after being subjected to high-heat treatment, thereby having the advantages of simple manufacturing process, low production cost, reliable performance and convenient assembly.

Description

The connector positioning retainer ring

Technical field:

The utility model relates to electric signal connector, particularly the connector positioning retainer ring on the connector.

Background technology:

In existing electric signal connector, installing and fixing generally of connector becomes double-body bike with insulator design, even trisome formula, connector is installed between the adjacent insulators, reach fixedly connector by two insulator obvolvents, said structure technology is relatively complicated, and cost strengthens, and is unfavorable for dismounting.The Chinese patent communique discloses the connector detent mechanism patent of the applicant's application, the patent No. is 200520134463.3, open day is on May 9th, 2007, the connector detent mechanism adopts port footpath big, the opening circular rings that other end bore is little, pass through the taper structure transition between the big small end, heavy caliber end internal orifice is a bell mouth shape, and establish a back-up ring in the outside of keeper, back-up ring is the opening circular rings, this detent mechanism cooperates defective tightness with insulator, and the location is reinforced sexual needs and further improved.

The utility model content:

The purpose of this utility model provides that a kind of manufacture craft is simple, the connector positioning retainer ring of dependable performance, characteristics such as easy to assembly, can well realize the positioning function of connector.

Scheme of the present utility model is: the circle wall of back-up ring is provided with the axially open gap, and the circle wall is provided with a plurality of claws.

The circle wall stamp out the fin that a plurality of tops are not blocked, fin outwards is bent to form claw along the top, or the circle wall stamp out the fin that the base is not blocked, fin outwards is bent to form claw along the base; Claw is a rectangle, and its area is less than the punching hole area.

The utility model has the advantages that: back-up ring is the opening cylinder, can be easily installed in the connector intermediate groove, and the terrace of appearing on the stage of the claw of back-up ring and insulator is clasped, and connector is fixed in the insulator, can conveniently take out connector by sprue-master.This back-up ring increases its elasticity through high-temperature heat treatment again by drawing, and manufacturing process is simple, and production cost is low, dependable performance, and assembling is easily.

Embodiment:

Referring to figs. 1 through Fig. 3, back-up ring 1 is non-enclosed cylinder, and the circle wall is provided with axially open gap 1.1, and the circle wall stamps out three fins, and the top of fin is not blocked, and links to each other with the circle wall, and fin outwards is bent to form three claws 1.2 along the top.Form punching hole 1.3 after the punching press of circle wall, the area of punching hole 1.3 is greater than claw 1.2 areas, and promptly a part is all excised on left and right, the limit, the ends three of fin, is bent into claw 1.2 again along the top, and claw 1.2 is a rectangle.

The manufacture method of back-up ring 1: elder generation by drawing, passes through high-temperature heat treatment with the strip base material again, encloses bent strip sheet then and becomes cylindrical shape, bends claw 1.2 at last.This back-up ring 1 is simple in structure, easy to make, through the claw 1.2 elasticity increase of high-temperature heat treatment; The quantity of claw 1.2 is set according to instructions for use, and the back-up ring material is beryllium-bronze, steel or stainless steel.

With reference to Fig. 4, connector 2 middle parts are provided with groove, and the bottom is provided with positioning boss 2.1, and these boss 2.1 external diameters are greater than connector 2 top external diameters.During assembling, back-up ring 1 opened gap 1.1 spreadings are inserted in from the top of connector 2, and back-up ring 1 shrinks when back-up ring 1 arrives groove location, and back-up ring 1 is fixed on the connector 2 firmly, and above-mentioned connector 2 can be jack or contact pin.The internal radius of back-up ring 1 is set according to the groove external diameter of connector 2, and general, back-up ring 1 internal diameter is slightly less than the groove external diameter of connector 2.

With reference to Fig. 5, Fig. 6, insulator 3 is shaped on " worker " font inner chamber, is undergauge step chamber 3.1 in the middle of the inner chamber, and the connector 2 that is with back-up ring 1 upwards inserts from the bottom of insulator 3, and the claw 1.2 of back-up ring 1 shrinks the step chamber 3.1 of passing insulator 3.Claw 1.2 arrives insulators 3 terrace of appearing on the stage, and claw 1.2 flicks, and is snapped in the terrace of appearing on the stage, and stops connector 2 to move down; The boss 2.1 of connector 2 just stops with insulator 3 inner chamber leave from office terraces and cooperates, stops on the connector 2 and moves, thus the location of realizing connector 2.As taking out connector 2,, can realize that arbitrarily more connector 2 is not but damaged in the thread-changing position by a pickup specific purpose tool.

The claw 1.2 of above-mentioned back-up ring 1 is upwards along the tooth design, and promptly the fin top is not blocked, and outwards is bent to form along the top; The claw of back-up ring 1 also can be downwards along the tooth design, and promptly fin is for falling " Qian " shape, and bottom is not blocked, outwards be bent to form along bottom, and connector 2 and insulator 3 structure otherwise designed, during assembling, the connector 2 that back-up ring 1 is housed inserts downwards from the top of insulator 3.
