Abstract

The utility model relates to the anti-shedding plug of a bayonet lock type round electrical connector and mainly comprises a head shell (1) that is locked together with a lock cap (2) sleeved outside through a flap gasket (4) and a check ring (5). A flange type anti skip ring (6) that is sleeved on the head shell (1) is arranged between the check ring (5) and the flap gasket (4). The check ring is partially inserted into inner groove of the lock cap and partially positioned on the flange plane of the anti skip ring (6). The added anti skip ring of the utility model can limit the check ring, and prevent the check ring from springing out so that the lock cap and the head shell on the plug can be locked and fixed, thus, the transmission of electrical connect signal is stable.

Description

The slip-off preventing plug of bail type round electric connector

Affiliated technical field

The utility model relates to a kind of electric connector, relates to a kind of slip-off preventing plug of bail type round electric connector specifically.

Background technology

No matter be forceful electric power or light current, as long as make electricity consumption that the existence of electric connector just be arranged, because electricity safe in utilization directly relates to we self safety, so people require more and more higher to the security protection performance of electric connector.The plug of existing bail type round electric connector, card cap and head capsule body are through plain washer and back-up ring locking, and back-up ring is seated on the plain washer and local the embedding in the card cap inside groove.Because of the environment that electric connector uses comparatively abominable, require the operating period more than at least five years, back-up ring is because of the soft or hard of material, long-term use may cause intensity and flexible deficiency and eject and come off, cause the card cap to separate with the head capsule body and whole electric connector is damaged, circuit signal interrupts, and transmission is unstable, directly influence the normal use of electric connector, useful life is short.

Summary of the invention

The purpose of this utility model is to have overcome because of back-up ring elastic strength deficiency, back-up ring ejects to come off and causes the card cap on the plug to separate with the head capsule body under high-intensity oscillation, and provide a kind of rational in infrastructure, increase the slip-off preventing plug that anti-jump circle stops the bail type round electric connector of back-up ring ejection.

In order to achieve the above object, the technical solution adopted in the utility model is: the slip-off preventing plug of bail type round electric connector comprises that mainly the card cap of head capsule body and overcoat is through plain washer and back-up ring locking, be provided with the anti-jump circle of the flange form that is placed on the head capsule body between back-up ring and plain washer, back-up ring is local to embed in the card cap inside groove, and the part is seated on the flange face of anti-jump circle.

After adopting above technical scheme, the beneficial effect that the utility model reaches is: set up the anti-jump circle of flange form between plain washer and back-up ring, the flange face of anti-jump circle is spacing to back-up ring, can effectively stop back-up ring to eject, make card cap and the locking of head capsule body on the plug firm, be electrically connected stable signal transmission, prolong the useful life of electric connector.

Description of drawings

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

In shown in Figure 1, head capsule body 1, card cap 2, wave-shaped ring 3, plain washer 4, back-up ring 5, anti-jump circle 6.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

The slip-off preventing plug of a kind of bail type round electric connector among Fig. 1, card cap 2 is enclosed within on the head capsule body 1, the socket inner chamber of card cap and head capsule body is provided with the anti-jump circle 6 of wave-shaped ring 3, plain washer 4, back-up ring 5, flange form that all is placed on the head capsule body, the anti-jump circle of flange form is seated on the plain washer 4, half is seated at back-up ring 5 on the flange face of anti-jump circle 6, second half embeds in the card cap inside groove, elasticity wave-shaped ring 3 by plain washer 4 bottoms compresses back-up ring 5, make card cap 2 firm with 1 locking of head capsule body, the flange face of anti-jump circle 6 is spacing to back-up ring 5, prevents that its vibration from coming off.

Claims

1, a kind of slip-off preventing plug of bail type round electric connector, the card cap (2) that mainly comprises head capsule body (1) and overcoat is through plain washer (4) and back-up ring (5) locking, back-up ring is local to embed in the card cap inside groove, it is characterized in that: be provided with the anti-jump circle of flange form (6) that is placed on the head capsule body (1) between back-up ring (5) and plain washer (4), back-up ring (5) part is seated on the flange face of anti-jump circle (6).
