Be formed as clamp area 100 between the U-shaped clamping section 101 of the clamping jaw 10；The clamp area 100 is along U-shaped side in up-narrow and down-wide
Fine crack.
Symmetrical U-shaped clamping section 101 forms clamp area 100, and the design of U-shaped structure has good elasticity, to improve
The clamping elasticity of clamp area 100, ensure that the reliability that contact pin is connect with terminal.And clamp area 100 is pressed as clamping
The direct contact site of the contact pin of key switch is designed in up-narrow and down-wide structure, can be the contact pin of key switch
Stable clamping force is provided, guarantees that the contact pin of key switch is connected with the steady contact of terminal, avoids key switch
Contact pin is detached from easily；Moreover, up-narrow and down-wide structure designs, be conducive to the clamping validity that clamp area 100 keeps permanent,
To be conducive to improve the service life of terminal, and then improve the service life of integrated connection device.
Moreover, in the U-shaped side of the close clamp area 100 of the U-shaped clamping section 101, the close clamping at top
The side in area 100 is chamfered.Relative to the design of straight angle, chamfer design can prevent the contact pin of key switch from existing
Since hard touching occurs for 100 entrance of clamp area caused by bit errors with terminal when into the clamp area 100 of terminal, thus
So that the contact pin of key switch smoothly, is easily inserted into the clamp area 100 of terminal, reduces hard touching and key is opened
The contact pin of pass and the damage of terminal, improve the service life of terminal, and then improve the service life of connector.
In the present embodiment, in the U-shaped side of the close clamp area 100 of the U-shaped clamping section 101, the close institute at top
The side for stating clamp area 100 is in rounded corner.The structure of rounded corner designs, so that 100 entrance of clamp area of terminal becomes more flat
It is sliding, so that the contact pin of key switch further smoothly, is easily inserted into the clamp area 100 of terminal.
Also, the U-shaped side far from the clamp area 100 of the U-shaped clamping section 101 upwardly extends to form the first end wall
102；First end wall 102 extends vertically to form the second end wall 103 from end along the direction far from the U-shaped clamping section 101；
One end far from first end wall 102 of second end wall 103 extends vertically inwardly is formed with welding foot 104, passes through
Two U-shaped clamping sections 101 extend to form two mirror-symmetrical welding foots 104, and welding is easier and firm welding, makes terminal
Stability in use it is higher.
Wherein, a semi-enclosed structure is collectively formed in first end wall 102, the second end wall 103 and welding foot 104.
In the present embodiment, convex ribs 105 have been provided projectingly on the outside of the intermediate position of second end wall 103, have been used for terminal 1
Positioning card is set in the ontology of connector.In the assembly of the ontology of terminal and connector, terminal is arranged in the ontology of connector,
By the design of convex ribs 105, terminal accurate positionin can be made to be arranged in the ontology of connector；Meanwhile passing through the card of convex ribs 105
Tightly, it further ensures that terminal is not easily to fall off in the ontology of connector, improves the assemble stable of integrated connection device.
In the present embodiment, the second end wall 103 on two clamping jaws 10 is connected with each other by crossbeam 106, thus real
Existing two clamping jaws 10 are connected with each other.Two clamping jaws 10 are connected by crossbeam 106, have ensured the elasticity between two clamping jaws 10, thus
Maintain the feasibility of the resilient clamp of clamp area 100.
Shown in Figure 2, key switch terminal for connector 1 and connector body 2 assembling of the present embodiment form whole
Connector.Wherein, connector body 2 includes connecting plate 21, positioning convex platform 22 and holding tank 23；Connecting plate 21 is for installing
Pcb board, positioning convex platform 22 with keyboard switch for contacting, and the contact that on positioning convex platform 22 there is perforation can accommodate key switch
Pin passes through；Holding tank 23 is opened on connecting plate 21 and is located on connecting plate 21 away from the both ends of the side of positioning convex platform 22
Edge；Holding tank 23 can accommodating terminal 1.Moreover, there is protrusion 24, protrusion 24 and the first end wall in the middle position of holding tank 23
102, the semi-closed structure that the second end wall 103 and welding foot 104 are collectively formed is mutually adapted.
When being assembled, the U-shaped clamping section 101 of terminal 1 is inserted into holding tank 23, and the clamp area 100 of terminal 1 and fixed
The perforation of position boss 22 is corresponding, and welding foot 104 stretches out outside the edge of holding tank 23；When pushing terminal 1, convex ribs 105 are along receiving
The inner wall perpendicular positioning of slot 23 is inserted into holding tank 23, is mounted on the accurate positionin of integral terminal 1 in holding tank 23 and clamping
And it is not easily to fall off, the assemble stable for being connected device is good.And simultaneously, protrusion 24 gos deep into the first end wall 102, the second end wall 103
In the semi-closed structure being collectively formed with welding foot 104, the assembling of integrated connection device is completed, packaging efficiency is high.
When the connector and key switch of assembling connect, the contact pin of key switch is inserted through positioning convex platform
22 perforation simultaneously can smoothly enter into the clamp area of terminal 1 100, and up-narrow and down-wide structure is presented in the clamp area 100 of terminal 1, from
And the contact pin for clamping key switch can be stablized, guarantee that the contact pin of key switch is connected with the steady contact of terminal 1.
Above embodiments are only the preferred embodiment of the utility model, be only that the technical solution of the utility model make into
The detailed description of one step, but the protection scope of the utility model and embodiment are without being limited thereto, it is any without departing from the utility model
Change, combination, deletion, replacement or modification for being made under Spirit Essence and principle etc. are included in the protection model of the utility model
In enclosing.
