Description
Technical field
The utility model relates to a kind of connector, specifically a kind of circlip type self-locking anti-loosing electric connector.
Background technique
The locking mode of typical electrical connector generally can be divided into following several: 1, bayonet type, and the coupling mechanism force after plugging together relies on
The pressure that spring generates, disadvantage is that cannot accomplish rigid locking, is easy come what is kept when connector weight is larger
It disengages；2, screw-type, coupling mechanism force are easy to loosen under the conditions of impacting compared with strong vibration by the friction between screw thread, some increasings
Ratchet ratchet has been added to prevent, but structure is complicated, increases manufacturing cost for product；3, straight cutting it is plug-type-stretching using steel ball
Contracting reaches connector locking, but complicated for operation, plugs together and needs rotational shell again afterwards in place, lock shell reset could, if
Omission just will appear locking loosely.
Utility model content
For the existing above problem, it is simple that the utility model provides a kind of structure, lock, unlock it is convenient, it is self-locking anti-
Pine, the firm circlip type self-locking anti-loosing electric connector of stable connection.
The utility model is achieved through the following technical solutions: a kind of circlip type self-locking anti-loosing electric connector, including plug and
Socket is equipped with one or the mobile steel balls of uniformly distributed more than two radial limits, head capsule in casing one end outer circle wall of plug
The body other end connects tail accessory, and casing central flange excircle guiding is outer to be socketed a nut, and seat shell body one end of socket is inserted
It closes in casing one end, seat shell body one end excircle is equipped with the locking arc-shaped ring groove of a circle accommodating steel ball, it is characterised in that:
Described nut one end is equipped with interior step, and radially limit is socketed between casing one end excircle and nut a retaining ring, locks
Ring is equipped with a circle and pulls boss with what interior step pushed against, and connection ripple bullet is pushed against between retaining ring inner face and head capsule central flange
Spring, nut other end inner wall wear the pull ring connect between nut and tail accessory through retainer ring spacing, and inner wall is set on the outside of the retaining ring
Have circle accommodating steel ball pulls arc-shaped ring groove, and it is equal to be equipped with radial together arc-shaped slot or twice circumference for inner wall on the inside of retaining ring
Cloth, radial arc-shaped slot, arc-shaped slot pass to retaining ring inner face, and described casing one end excircle is located at steel ball and middle part
Outer wall between flange is equipped with the jump-ring slot of jump-ring slot on one section of circumferencial direction or two sections or more circumference uniform distribution, in jump-ring slot
Circlip is set, and circlip, which is equipped with, elastic can extend in arc-shaped slot, the arc spring leaf of corresponding fitting arc-shaped slot arc section, arc
Shape reed and steel ball are corresponded and are not on the same axis of casing outer wall.
Further, the circlip includes arc seat board, connection sheet and arc spring leaf, and arc seat board is bonded jump-ring slot arc
Slot bottom, one end tilted connection sheet of the arc seat board on the circumferencial direction locating for the jump-ring slot connect arc spring leaf, arc spring leaf
Arc circumference central axis is parallel with circumference axis center axis locating for jump-ring slot.
Further, the arc spring leaf is located at arc seat board middle position.
Further, one end of the arc spring leaf connects connection sheet, and the other end connects the extension reinforced sheet being obliquely installed.
Further, described to extend the other end of the reinforced sheet without departing from arc seat board.
Further, described casing one end inner wall is equipped with guiding rib, and seat shell body one end outer wall is equipped with guide groove, guiding rib
Correspondence plugs together guide groove.
Further, the head capsule internal guide, which is worn, connects pin hole component, and one end of pin hole component is by casing inner wall step
Inner side limiting-position, the other end are sealed by insulation silica gel encapsulating area and are limited.
Further, the outside that joint housing inner wall step is worn in one end of the pin hole component is sealed by sealing ring.
The jump-ring slot of circumference equal dividing is dispersed on plug casing, jump-ring slot slot bottom is matched with the arc seat board of circlip, card
Spring groove deep can make the arc spring leaf of the circlip of free state expose casing cylindrical surface, at the top of the arc spring leaf for pressing circlip,
It can sink in jump-ring slot completely.
Circlip by highly elastic material mold blanking integrated molding be made connected arc seat board, connection sheet, arc spring leaf and
Extend reinforced sheet, low manufacture cost, part consistency of performance is good, convenient for producing and guaranteeing that entire block quality is steady in enormous quantities

Effect reduces dynamics needed for rotating, while arc spring leaf being protected not acted on by rigid push-pull effort, and extend arc spring leaf uses the longevity
Life.
When retaining ring is assemblied on plug, steel ball is inwardly limited on casing by retaining ring inner wall, while circlip being set
Enter in jump-ring slot, arc spring leaf joint match is caught in arc-shaped slot by the arc-shaped slot notch of retaining ring inner face, at this time
Retaining ring is rotated, by connection sheet or extension reinforced sheet, just or reversely guiding rotation forces arc spring leaf is pressurized in indentation jump-ring slot,
Arc spring leaf circumferentially deflects away from arc-shaped slot, and arc-shaped slot is rotated to steel ball position, and steel ball carries out realizing lock in arc-shaped slot
The assembly of tight ring.
When plug, socket plug together, retaining ring inner hole is dispersed with the locking with steel ball corresponding number and angle on casing
Arc-shaped ring groove, after plugging together locking, locking arc-shaped ring groove is corresponding under steel ball, at this time rotary connector, steel ball deflect away from arc-shaped slot by
Casing inner wall squeezes in indentation locking arc-shaped ring groove, and the arc spring leaf of synchronous circlip is just corresponded to arc-shaped slot position and bullet
It plays joint match to be caught in arc-shaped slot notch and be caught in arc-shaped slot, locking arc-shaped ring groove is caught in by steel ball and realizes plugs and sockets
Grafting locking, and be aided with arc spring leaf and be caught in arc-shaped slot and retaining ring circle rotation is locked, further to plugs and sockets
Grafting locking be limited, when unlock, needs to apply a biggish turning moment, can just overcome the elasticity of circlip, and grafting is stablized
It is firm, have the function of self-locking anti-loosing.
When needing to pull release, pull ring is pulled, pull ring drives nut post-tensioning through retaining ring, and nut step in one end is drawn
Pulling boss in dynamic retaining ring makes retaining ring that ripple spring be overcome to move back along axial direction, and arc spring leaf can be moved in arc-shaped slot along its slot
It is dynamic, keep steel ball outer fix corresponding to when the circle of inner wall one pulls at arc-shaped ring groove on the outside of retaining ring when retaining ring is mobile, steel ball is de-
It falls into and is pulled in arc-shaped ring groove out, disengage the locking arc-shaped ring groove of seat shell body, casing can be pulled directly and seat shell body at this time
Locking has zipper unlocking function.After pulling, pull ring is unclamped, under ripple spring active force, retaining ring Forward, steel ball is by drawing
De- arc-shaped ring groove falls into casing inner wall, and arc spring leaf can be moved in arc-shaped slot along its slot, after retaining ring resets, rotation lock
Tight ring falls into steel ball in arc-shaped slot.
