Protruding stretch slot matches, and contact pin is formed powerful chucking power so that the grafting of contact pin is reliable and stable, and tongue and
Stretch slot indefatigability deforms, and effectively extends the service life of pin hole.Further, by using two or more stretch slots
Structure so that it is and form three-jaw or multijaw clamp structure between pressure tongue, can further improve the pin hole clamping dynamics to contact pin so that it is
Connect more solid and reliable, due to use pressure tongue structure, pressure root of the tongue portion be wider globoidal structure, this globoidal structure be fabricated to by
Gradually pressing structure, makes pressure tongue portion deform upon, and puts down and lies prone on contact pin, increases contact area and frictional force, slotting when outwards extracting
During pin, stop contact pin to move out, form dynamic protection, drastically increase the good contact of electric connector contact pin and pin hole
Can, and make connection more stable, safe and reliable.
Jack socket joint one end head arranges the annular tapering guide frame caved inward, it is to avoid pin hole internal diameter occurs bigger change
Change, can effectively ensure that jack and contact pin, to concentricity time slotting, pin hole body are laid with through hole, beneficially the sky within pin hole
Gas is discharged rapidly, makes in plating processes, and plating solution is easier to be full of inside and outside pin hole, fully and uniformly plates inside and outside full pin hole, carries
High product quality.
Present configuration is simple, and grafting is reliable and stable, and chucking power is powerful, and indefatigability deforms, and is effectively improved syringe needle and pin
Hole connection reliability, and effectively extend pin hole service life, practical.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the present invention is further described:
Fig. 1 is the structural representation of conventional pinhole；
Fig. 2 is the main TV structure schematic diagram of pin hole of the present invention；
Fig. 3 is the side-looking structural representation of pin hole of the present invention；
Fig. 4 is the partial enlargement structural representation in Fig. 3 at A；
Fig. 5 is the backsight structural representation of pin hole of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is expanded on further.
Referring to shown in Fig. 1: traditional electric connector pin hole, including pin hole body 1, it offers symmetry in pin hole both sides
Axially open 2 so that pin hole both sides form clamp structure, owing to pin hole internal diameter is big compared with pin diameter, then need pin hole
Two side portions clamps so that it is deformation, and draws close to centre, then makes opening part form the ellipsoidal structure to contract, when inserting
When pin inserts, only forming some point cantact at the position that its internal diameter formed is minimum, contact area is little, and owing to offering axle
To opening 2, greatly destroy the cohesive force of pin hole, so that the clamping dynamics of contact pin is had a greatly reduced quality by pin hole, switching performance
Difference.
As shown in Figure 2 and Figure 3: the electric connector pin hole of the present invention, including pin hole body 1, described pin hole body 1 top
Be provided with at a certain distance from top pressure tongue 3, described pressure tongue 3 root is wider globoidal structure, front end be narrower cambered surface or
Planar structure, and root is gradually transition pressing structure to front end, makes pressure tongue produce resilience force.On the body 1 of corresponding pressure tongue 3
There is the breach matched with pressure tongue 3, the body 1 at breach back is provided with the stretch slot 5 parallel with axis.Described pin hole is originally
Body 1 upper end is provided with the annular tapering guide frame 4 caved inward, and is prevented effectively from pin hole internal diameter generation large change, carries
High pin hole and contact pin to slotting concentricity, and contact pin is formed guiding function, utilizes the smooth insertion of contact pin.Described stretch slot
5 is 2, is distributed in isosceles triangle in the circumference of pin hole body 1 with described pressure tongue 3 three, the most each stretch slot 5 and pressure tongue
Line angle between the line of 3 and two stretch slots 5 is equal.By the structure using pressure tongue 3 to match with stretch slot 5, press tongue 3 bullet
Property deformation quantity big, and match with inwardly protruded stretch slot 5, forming linear contact lay dough-making powder with contact pin contact, to contact pin formation
Powerful chucking power, so that the grafting of contact pin is reliable and stable, and tongue 3 and stretch slot 5 indefatigability deform, and effectively extend
The service life of pin hole.Three-jaw clamp structure is formed between pressure tongue 3 and stretch slot 5, owing to using pressure tongue structure, slotting when outwards extracting
During pin, the wider cambered surface of root of pressure tongue 3, under the active force pressed down, deforms upon, and puts down and lies prone on contact pin, increases contact surface
Long-pending and frictional force, stops contact pin to move out, forms dynamic protection, drastically increases the good of electric connector contact pin and pin hole
Contact performance, and make connection more stable, safe and reliable.
It is further preferred that referring to shown in Fig. 4, the head of described pressure tongue 3 is provided with secondary guide frame 3-1, this secondary
Guide frame 3-1 is ironed cambered structure or planar structure, when contact pin inserts, is concaved by pin hole body 1 upper end
The annular tapering guide frame 4 fallen into, carries out one-step boot to contact pin, and make contact pin inserts pin hole smoothly, and axially positions,
Make contact pin successfully go deep into pin hole by secondary guide frame 3-1, and make pressure tongue 3 successfully be pressed on contact pin, it is to avoid contact pin will
Pressure tongue 3 bending, improves safe and stable, reliability that contact pin inserts.
Preferably, referring to shown in Fig. 5, described stretch slot 5 and described pressure tongue 3 three are in the circumference of pin hole body for another step
Be distributed in equilateral triangle, i.e. three is uniformly distributed in the circumference of pin hole body 1.With described pressure tongue 3 on described pin hole body 1
Relative side axially on be laid with through hole 6, described through hole 6 is circular hole and/or elongated hole and/or elliptical aperture, makes coating processed
Cheng Zhong, plating solution is easier to be full of inside and outside pin hole, fully and uniformly plates inside and outside full pin hole, improves product quality.
Applicant passes through pilot sample, plugs experiment continuously, and plug 800-1000 time, still has good folder continuously
Holding force, chucking power keeps within the limits prescribed, greatly exceeds 500 tall and straight standards of national Specification.
Technical scheme is not restricted in the range of embodiment of the present invention.The most detailed description of the present invention
