Abstract
The utility model discloses a kind of locking formula sleeves, turn spring including being arranged in sleeve, the spring barrel that turns is that the grizzly bar for being connected to both ends by a plurality of inclination is constituted, it is described to turn spring helically distorted-structure, the spring both ends that turn offer multiple recessed buckles, the sleeve both ends offer multiple convex clips and buckle, and the recessed convex clip button that is clasped is fixedly connected.A kind of windup-degree of the utility model offer is constant, and production efficiency is high, the locking formula sleeve of low production cost.
Description
Technical field
The utility model is related to the conducting interconnection technique fields more particularly to a kind of locking formula sleeve of power supply and signal.
Background technology
With the rapid development of electronic product, the relevant spare and accessory parts of electronic product also quickly grow up therewith, especially
It is electric connector contact.
Chinese patent literature CN202772301U discloses a kind of jack contact, including the hat spring being arranged in sleeve and one
Lantern ring, the come of age end in the same direction of spring of the sleeve are held in the lantern ring.To further strengthen the lantern ring on sleeve
Crystallized ability, the sleeve outer wall be equipped with annular groove；With setting in lantern ring outer shroud end riveting, make between hat spring and sleeve
Connection more closely, it is firm.But above-mentioned technical proposal is during annular groove of the lantern ring riveting in sleeve outer wall, Guan Huangchu
Predetermined angle is caused to change since reply phenomenon can occur for its torsion structure in free state, and such structure produces
Efficiency is low, and production cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of windup-degree is constant, and production efficiency is high, low production cost
Locking formula sleeve.
Technical solution is used by locking formula sleeve disclosed by the utility model：A kind of locking formula sleeve, including wear
Turn spring in sleeve, the spring barrel that turns is that the grizzly bar for being connected to both ends by a plurality of inclination is constituted, and the spring that turns helically is turned round
Bent structure, the spring both ends that turn offer multiple recessed buckles, and the sleeve both ends offer multiple convex clips and buckle, the recessed card
Snap fit is closed convex clip button and is fixedly connected.
Preferably, the quantity at least two for turning the recessed buckle of spring either end.
It is preferably, described that turn the recessed buckle quantity in spring both ends identical.
Preferably, the recessed buckle quantity is identical as convex clip button quantity.
Preferably, a plurality of grizzly bar is vertical bar, and a plurality of grizzly bar central point constitutes larynx diameter, the larynx diameter
Diameter be less than and turn the diameter of spring both ends annulus.
Preferably, the grizzly bar and turn the angle of spring cross section between 30 ° to 60 °.
The advantageous effect of locking formula sleeve disclosed by the utility model is：1, turn the recessed buckle in spring both ends and sleeve both ends convex clip
Snap fit conjunction be fixedly connected can anti-rotation stop spring occurs opposite sliding on sleeve extending direction, 2, the convex snapped-in position in sleeve both ends be
It is changeless, turn the recessed buckle in spring both ends and can smoothly be buckled to fix with sleeve both ends figure to must satisfy its windup-degree not
Become, and buckle structure can anti-rotation stop spring reply phenomenon, therefore the windup-degree for turning spring will not change, 3, buckle structure
Simply, to make its production efficiency greatly promote, and its cost payout is greatly reduced.
Description of the drawings
Fig. 1 is the assembling schematic diagram of the utility model locking formula sleeve；
Fig. 2 is the structural exploded view of the utility model locking formula sleeve；
Fig. 3 is the larynx gauge structure schematic diagram of the utility model locking formula sleeve；
Fig. 4 is the sectional view of the utility model locking formula sleeve.
Specific implementation mode
The utility model is further elaborated and is illustrated with reference to specific embodiment and Figure of description：Please refer to figure
1 and Fig. 2, a kind of locking formula sleeve, including turn spring 10 and sleeve 20.
It is that the grizzly bar 11 for being connected to both ends by a plurality of inclination is constituted to turn 10 barrel of spring, turns the helically distorted-structure of spring 10, turns
10 both ends of spring offer multiple recessed buckles 12.
Referring to FIG. 3, a plurality of grizzly bar 11 is vertical bar, 11 central point of a plurality of grizzly bar constitutes larynx diameter 30, the diameter of larynx diameter 30
Less than the diameter for turning 10 both ends annulus of spring, the thick intermediate thin structure in a both ends is formed.30 structure of larynx diameter positioned at middle part is convenient for
Lock plug-in unit.With plug-in unit plug elastic deformation can occur for a plurality of grizzly bar 11, keep plug operation more smooth.
Referring to FIG. 4,20 both ends of sleeve, which offer multiple convex clips, buckles 21, turns spring 10 and be arranged in sleeve 20, recessed buckle
12 cooperation convex clip buttons 21 are fixedly connected.
Turn 10 both ends of spring it is recessed buckle 12 with 20 both ends convex clip of sleeve buckle 21 cooperation be fixedly connected can anti-rotation stop spring 10 covering
Opposite sliding occurs on 20 extending directions of cylinder；It is changeless that 20 both ends convex clip of sleeve, which buckles 21 positions, turns the recessed card in 10 both ends of spring
Button 12 can smoothly buckle 21 with 20 both ends graph card of sleeve and coordinate fixed its windup-degree that must satisfy constant, and buckle structure can be prevented
The reply phenomenon of rotation stop spring 10, therefore the windup-degree for turning spring 10 will not change；Buckle structure is simple, to make its production
Efficiency greatly promotes, and its cost payout is greatly reduced.
Turn the quantity at least two of the recessed buckle of 10 either end of spring 12, multiple buckles are fixed to make structure more consolidate.
It is identical to turn 10 both ends of spring, 12 quantity of recessed buckle, makes to turn 10 both ends of spring to be more uniformly stressed.
12 quantity of recessed buckle are identical as 21 quantity of convex clip button.
Grizzly bar 11 and turn the angle of 10 cross section of spring between 30 ° to 60 °, this range within angle can ensure inserting for plug-in unit
It pulls out better.
The utility model provides a kind of locking formula sleeve, and 1, turn the recessed buckle in spring both ends and sleeve both ends are convex is buckled to fix
Connection can anti-rotation stop spring occurs opposite sliding on sleeve extending direction, 2, the convex snapped-in position in sleeve both ends be to immobilize
, turning the recessed buckle in spring both ends can smoothly be buckled to fix that must satisfy its windup-degree constant with sleeve both ends figure, and block
Buckle structure can anti-rotation stop spring reply phenomenon, therefore the windup-degree for turning spring will not change, 3, buckle structure it is simple, to
Its production efficiency is set to greatly promote, and its cost payout is greatly reduced.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
