Specific embodiment
Embodiment, as shown in Fig. 1 to Fig. 5: two-in-one photovoltaic connector terminal assemblies, including male terminal unit 10 and mother
Hold terminal unit 20.Wherein, which includes female end including male terminal main body 11, the female end terminal unit 20
Terminal bodies 21.It is male terminal unit 10 positioned at right in Fig. 1, is female end terminal unit 20 positioned at left.
Specifically:
The male terminal main body 11 is formed in such a way that sheet metal is rolled by punching press.That is, male terminal master
Body 11 has thin-walled hollow structure.Meanwhile the right part of the male terminal main body 11 is equipped with the card slot 111 of annular, in the card slot 111
It is arranged with Non-return ring 12, the side wall of the Non-return ring 12 is equipped with the male end stopping elastic sheet 121 that inner end keeps left, outer end is kept right.It is so-called
Inner end refers to one end of the axle center line position close to the Non-return ring 12, conversely, the axle center line position far from the Non-return ring 12
One end is outer end.The right end of the male terminal main body 11 is formed with the male end riveting cup 112 that section is in "U" shaped, the male end riveting cup
112 are used for connection cables.
The male terminal main body 11 is completed the process with the Non-return ring 12 preferably by two-in-one punching press integrated molding.That is, will
The plate for preparing the male terminal main body 11 and the plate for preparing the Non-return ring 12 are superimposed together, and are then rushed jointly by mold
After pressure, which is directly set in the outside of the male terminal main body 11.Later, in order to both make what is combined more to step up
It is close, then connect the male terminal main body 11 with 12 spot welding of Non-return ring by laser solder joint.
The female end terminal bodies 21 are formed in such a way that sheet metal is rolled by punching press.Similarly, female end terminal master
Body 21 has thin-walled hollow structure, and for the insertion of the male terminal main body 11, the right part of the female end terminal bodies 21 is inevitable
Opening.Meanwhile the right part of the female end terminal bodies 21 is equipped with conductive contact area 211.The diameter at the middle part in the conductive contact area 211
Less than the diameter at the both ends in the conductive contact area 211 to form inner concavity.That is, the vertical of the conductive contact area 211 cuts
Face is in intermediate thin dolioform.Several strip-shaped holes extended in the lateral direction are formed at the conductive contact area 211
2111.Strip-shaped hole 2111 generally no less than 3.The inner shrapnel 2112 of arc is equipped in strip-shaped hole 2111.The female end terminal bodies
21 left end is formed with the female end riveting cup 212 that section is in "U" shaped, which is used for connection cables.
The outer cover of the female end terminal bodies 21 is equipped with sheath 22.The sheath 22 can be fixed on this by way of riveting
The outside of female end terminal bodies 21, and can reinforce fixing later by way of laser spot welding.The sheath 22 uses metal plate
Material is formed in such a way that punching press rolls.That is, the sheath 22 is equally hollow thin-wall structure.In the present embodiment, the female end terminal
Main body 21 and the sheath 22 are preferably equally completed in such a way that two-in-one punching press is integrally formed processing.That is, the female end will be prepared
The plate of terminal bodies 21 and the plate for preparing the sheath 22 are superimposed together, and after the common punching press of mold, make the sheath 22
Directly it is set in the outside of the female end terminal bodies 21.Later, it by the female end terminal bodies 21 and can be also somebody's turn to do by laser solder joint
22 spot welding of sheath connection, so that the two combines more closely.
The left part side wall of the sheath 22 is equipped with the female end stopping elastic sheet 221 that inner end is kept right, outer end keeps left.Equally, so-called
Inner end refers to one end of the axle center line position close to the sheath 22, conversely, one end of the axle center line position far from the sheath 22
For outer end.The right part side wall of the sheath 22 is equipped with the outer elastic slice 222 of several arcs, and outer elastic slice 222 and inner shrapnel 2112 are two-by-two
It is corresponding.That is, the position of outer elastic slice 222 and inner shrapnel 2112 is overlapped two-by-two, and in other words, outer elastic slice 222 is withstood on after assembling in place
The outside of corresponding inner shrapnel 2112, so that inner shrapnel 2112 is not likely to produce permanent deformation.When in use, the male terminal main body
11 left part from right to left insertion the female end terminal bodies 21 inside, and the middle part of inner shrapnel 2112 be in bending state from
And be closely extruded on the side wall of the male terminal main body 11, keep the male terminal main body 11 and the female end terminal bodies 21 real
Existing good electrical contact.
Optimization:
Outer elastic slice 222 includes open outer elastic slice 2221 and closed outer elastic slice 2222, and open outer elastic slice 2221 and closing
The outer elastic slice 2222 of formula is disposed adjacent.That is, there is 1 closed outer elastic slice 2222 between 2 adjacent open outer elastic slices 2221,
And there is 1 open outer elastic slice 2221 between 2 adjacent closed outer elastic slices 2222.So-called open outer elastic slice 2221 refers to
Be have with ontology disconnection to it is slotting when can movably push elastic slice；So-called closed outer elastic slice 2222 refers to that elastic slice does not break with ontology
It opens and connects together, it is only force-applied at depression in centre when to slotting.In this way, this closing combines the elastic piece structure of open architecture
Design, to it is slotting when form Multi-contact, contact it is relatively reliable, stablize, impedance is lower, and the service life is more longlasting.
Positioning port 1111, the locating button which is equipped with and positioning port 1111 matches are equipped in the card slot 111
122.That is, locating button 122 can be fastened in corresponding positioning port 1111, so that Non-return ring 12 is not easily to fall off.
In addition:
There is longitudinal sliding motion in the female end terminal bodies 21 in the sheath 22 in order to prevent, on the side wall of the female end terminal bodies 21
Also settable location hole 213, and locating piece 223 corresponding can be provided on the inner wall of the sliding sleeve 22, locating piece 223 is stuck in phase
In the location hole 213 answered.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
