Abstract
The utility model discloses a kind of ultrathin board to board connector, wherein base includes the metal shell, plastic body and conductive terminal being assembled together, the metal arm front end of conductive terminal is set as double U-shaped bodies, is equipped with slope on vertical metal arm top, along slope to having metal bump；The multiple bump contacts of distribution in upper U-shaped body, lower U-shaped body forms groove, for retaining scaling powder and foreign matter, double U-shaped bodies are connected with the rear end of metal arm by metal beam, the other end and pad solder of metal beam, lower U-shaped groove floor are equipped with metal bump, are used to support PCB circuit board.The problem of the design makes the elasticity of contact improve, and rigidly dies down, and disperses stress, and metal terminal is plastically deformed is resolved.Since corresponding master-slave seat coupling mechanism force becomes strong, the fixing of contact becomes strong.The design of double U-shaped bodies avoids foreign matter from being scattering on the contact that other positions are easily adhered nearby everywhere, causes to be not turned on appearance so that leading to the problem of foreign matter.
Description
Technical field
The utility model relates to a kind of ultrathin board to board connector, hand-held for mobile phone, digital camera, intelligence wearing etc.
The connection of the portion the computer products Inner such as formula electronic product, NB, PAD signal circuit.
Background technique
Currently, board to board connector is the development trend for becoming miniaturization slimming, the limit is arrived when such connector is thin
When degree, the metal conductive terminal arm of force of contact can become very short, so that tine resiliency be made to be deteriorated, rigidity is strong, be easy hair
Raw plastic deformation.The coupling mechanism force of product is set to be deteriorated, contact fixing is deteriorated.Meanwhile when such connector it is thin to extreme degree when,
For preventing scaling powder from climbing to the effect variation of contact point when the welding of product patch.
Board to board connector product on the market is all single-point or the kinds of point mode way of contact at present.Such board to board connector
It is all that the foreign matter for the oxide and foreign matter at contact position being removed using scraping mode, but scrape does not do product in product
Dirt slot, foreign matter is easy to adhere on contact point in its vicinity, so as to cause the function hidden danger not contacted.
Summary of the invention
Purpose of the utility model is to solve problem of the existing technology, emphasis carries out the structure of conductive terminal
Innovative design is particularly developed a kind of new ultrathin board to board connector.
The technical scheme adopted by the utility model is that：A kind of ultrathin type board to board connector, including master-slave seat, feature exist
In, wherein the base includes the metal shell, plastic body and conductive terminal being assembled together, the gold of the conductive terminal
Belong to arm front end and be set as the U-shaped body of a pair of up and down being superimposed, slope is equipped on vertical metal arm top, along slope to lower tail
End is equipped with the first metal bump, for fixing with plastic body；Left and right and the multiple protrusion touchings of bottom distribution in upper U-shaped body
Point is connected a lower U-shaped body in upper U-shaped body bottom, and for keeping the arm of force elongated, lower U-shaped body forms groove, for retaining
Scaling powder and foreign matter are connected between double U-shaped bodies and vertical metal arm by the first metal beam, the other end of vertical metal arm
It is connected the second metal beam, is used for and pad solder, lower U-shaped body bottom surface are equipped with the second metal bump, are used to support PCB circuit
Plate.
Beneficial effect caused by the utility model is：
1. being connected out in upper U-shaped bottom since conductive terminal devises the U-shaped body of a pair of up and down being superimposed
One small U-shaped, the left and right contact and the bottom contact arm of force of the upper U-shaped made in this way are all elongated, can make the bullet of contact in this way
Property improves, and rigidly dies down, so that stress be made to disperse, the problem of metal terminal is plastically deformed is resolved.Terminal bullet simultaneously
Property improves, and corresponding master-slave seat coupling mechanism force will become by force, and the fixing of contact will become strong.
2. scaling powder is preferentially climbed in groove when the design of the groove of lower U-shaped may make Product jointing, to avoid helping
Solder flux crawls toward the position of contact point.
3. the foreign matter that the design of the groove of lower U-shaped can be such that BTB product scrapes when fastening and using is fallen into groove,
To avoiding foreign matter from being scattering on the contact that other positions are easily adhered nearby everywhere, so that generate what foreign matter caused to be not turned on
Problem occurs.
4. designing a metal bump in lower U-shaped groove floor, this metal bump can play a supporting role.Work as conducting end
After the multiple contacts of son are pressed, when conductive terminal moves down certain displacement amount, this metal bump can be supported in PCB circuit board, from
And this conductive terminal is made not generate over-large displacement amount, i.e., plastic deformation will not be generated by over-voltage.

Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail：
Referring to figs. 1 to Fig. 6, the ultrathin board to board connector of the design includes master-slave seat, wherein base includes being assemblied in
Metal shell 1, plastic body 2 and conductive terminal 3 together, the metal arm front end of conductive terminal 3 are set as being superimposed upper
Lower a pair of U-shaped body is provided when vertical metal arm top is equipped with slope 3.1, assembles for conductive terminal with plastic body and is led
The effect of drawing is equipped with the first metal bump 3.2 along the downward tail end in slope 3.1, for fixing with plastic body；In upper U-shaped body 3.3
Interior left and right and bottom are distributed multiple bump contacts 3.4, are connected a lower U-shaped body 3.5 in upper 3.3 bottom of U-shaped body, for making
The arm of force is elongated, and lower U-shaped body 3.5 forms groove, for retaining scaling powder and foreign matter, between double U-shaped bodies and vertical metal arm
It is connected by the first metal beam 3.6, the other end of vertical metal arm is connected the second metal beam 3.7, it is used for and pad solder,
