Optionally, described connecting plate is a plane, and described connecting plate offers through hole, and described terminal has at least a part to extend to space perpendicular to through hole plane.When the pin of key switch and LED is through through hole, pin will be connected with terminal.
Further, described terminal comprises one or more intermediate plate, and described terminal stands on the edge of through hole, and described terminal is at the upper surface of connecting plate or lower surface.Terminal is set to clip type terminal, is conducive to the pin of key switch and LED and the connection of terminal, and improves the stability of key switch and LED.
Optionally, described terminal comprises one or more intermediate plate, and described terminal stands on the upper surface of connecting plate.Key switch and direct insertion LED can directly insert clip type terminal.
Preferably, described reflow soldering process pin has at least a part to be located on connecting wall, and described reflow soldering process pin stretches out connector carrier.Be conducive to pad reflow soldering process pin being welded in pcb board.
Preferably, the surrounding of described terminal is provided with terminal wall, and described terminal wall is around described terminal, and described terminal wall and connecting plate are connected to form the terminal wall of blind hole or hollow.Terminal wall can extend the useful life of terminal, and makes pin and terminal compact siro spinning technology.
Further, described terminal is not higher than connecting wall.When key switch is installed, do not increase the height of keyboard.
The utility model beneficial effect is: when installing key switch, reflow soldering process pin is welded in the pad of pcb board by reflow soldering process, key switch is directly connected with the terminal of connector with the pin of non-SMTLED lamp, without the need to by Wave crest Welding on pcb board.Therefore, the utility model, when after-sales service, only need be extracted key switch and load, without the need to welding.So, be convenient to the LED changing key switch and non-SMT.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
A kind of New connector 5, comprises connector carrier and connector.Described connector carrier comprises connecting plate 1, connecting wall 14, hanging platform 13.
The edge part of connecting plate 1 upwards extends to form connecting wall 14, and hanging platform 13 is outwardly formed at the top of described connecting wall 14.Hanging platform 13 damages connector when can effectively prevent user's violence from knocking keyboard.
Connecting plate 1 is a plane, and connecting plate 1 offers 6 through holes 8.Wherein 4 through holes 8 are positioned at the edge of connecting plate 1, in alignment.When installing direct insertion LED, the pin of direct insertion LED is through these 4 through holes 8.When installing key switch 7, the pin of key switch 7 is through two other through hole 8.Connector is located at the surface of connecting plate 1, and connector is electric conducting material.
Connector comprises terminal 21, admittance portion 22 and reflow soldering process pin 23, and terminal 21, admittance portion 22 and reflow soldering process pin 23 connect and compose one successively.Connector is in band shape.
Terminal 21 stands on the upper surface of connecting plate 1, and terminal 21 comprises two intermediate plates, and these two intermediate plates relatively arrange and form double fastener blade terminal.The shape of terminal is " Y " shape.Terminal is set to double fastener blade terminal, and the pin of key switch 7 and LED directly inserts double fastener blade terminal, without the need to through wave-soldering.And double fastener blade terminal is conducive to the pin of key switch 7 and LED and the connection of terminal, and the stability of key switch 7 and LED.Described terminal 21 comprises key switch splicing ear 211 and direct insertion LED splicing ear 212.The quantity of key switch splicing ear 21 is 2, and the quantity of direct insertion LED splicing ear 212 is 4.Direct insertion LED splicing ear 212 is positioned at the edge of connecting plate 1, and forms straight line.
The surrounding of terminal 21 is provided with terminal wall 14, and described terminal wall 14 is around described terminal, and terminal 21 is close to terminal wall 14, and terminal wall 21 and connecting plate 1 are connected to form the terminal wall of blind hole or hollow.The terminal wall of hollow mentioned here refers to that terminal wall is without upper surface and lower surface, only has side.Terminal wall 14 can extend the useful life of terminal, and makes pin and terminal 21 compact siro spinning technology.The height of terminal 21 and terminal wall 14 is less than or equal to the height of hanging platform 13 or pcb board 4.When key switch 7 is in time reinforcing iron plate 7 inserted terminals 21, keyboard height can't not be increased.
Reflow soldering process pin 23 some be located on connecting wall, and stretch out connecting wall.The height of reflow soldering process pin is lower than the height of hanging platform.Connecting wall 12 effectively can stablize reflow soldering process pin 23 and connecting plate 1.When installing reflow soldering process pin 23, reflow soldering process pin 23 is welded in the pad of pcb board 4 by reflow soldering process.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
