In the fire detector of fire product, alarm button, modules and other products, because its special operating state generally all is divided into the middle seat of circuit with two parts of base of contact, the function of contact chip is exactly to take full advantage of its different form will with the base contact chip, to be connected with the middle seat lead-in wire (or haptic element) of printed circuit board (PCB) with different combinations, according to the functional requirement difference, the structure of contact chip is also ever-changing.
[summary of the invention]
The purpose of this utility model, the lead-in wire (or haptic element) that is to solve the printed circuit board (PCB) in detector for fire alarm system in prior art need be connected with the base contact chip, cause the technical barriers such as complex structure, difficult wiring, provide a kind of and connect, adopt different contact chip square crossings connect and can realize a kind of cross-contact structure be connected with base contact for detector circuit be connected without wiring.
For achieving the above object, design a kind of for detector circuit and base contact square crossing contact structures, comprise contact chip, middle seat, slot, printed circuit board (PCB), base and lower contact chip, it is characterized in that described middle seat is provided with some slots, fixing upper contact chip close contact printed circuit board in slot, base be provided with some lower contact chips and with upper contact chip close contact.
All adopt the bayonet socket syndeton between described upper contact chip, middle seat, slot, printed circuit board (PCB), lower contact chip and base.
Described upper contact chip top is inverted L-shaped, and upper contact chip top contacts with printed circuit board (PCB) and is connected, and upper contact chip bottom is that elasticity prong form is x shape for clamping lower contact chip.
Described lower contact chip top is L shaped structure, and for contacting upper contact chip, both sides, lower contact chip bottom are provided with the connection projection, with the base bayonet socket, are connected.
Described middle seat is provided with the slot of four fixing upper contact chips and the plastic base of fixed printed board, and upper contact chip inserts in slot fixing, and contact chip mix proportion under close contact printed circuit board (PCB) and base.
Described four upper contact chips insert the slot slotted eyes and run through the location, bottom downwards, and with lower contact chip close contact, after lower contact chip vertically enters to insert under one of formation along connecting terminal the contact that is connected with the base contact square crossing.
Described middle seat slot bottom is provided with an open-work grain.
The utility model compared with prior art, its advantage is: employing be the square crossing contact structures, not only can expand application for detector for fire alarm system and make it structure diversification, also given full play to structural advantage, guaranteed that when mounted having reduced wiring in the reliable situation of contact connects, simple in structure; Utilize bayonet socket to be fixed, guarantee that the contact of each parts fixation on detector and plated circuit is reliable, not yielding when the product shipping, this Standard rationally, expanded line function, of many uses, and can reduce costs, raise the efficiency.
