Description
Technical field
The utility model relates to a kind of electric connector, particularly relates to a kind of FPC connector.
Background technology
FPC connector is as flexible circuit board/bus bar connector, and its major function is for the transmission as the digital signal on the electronic products such as notebook computer, automobile-used DVD, navigator, display, point reader and power supply of all kinds of mobile communication equipment and all kinds of individual terminal devices.
The structure that current FPC connector is commonly used has drawing and pulling type structure and front cover-lifting type structure, drawing and pulling type structure is inconvenient because press strip operation uses, pull block is often because operation makes firmly excessive damage press strip (break and buckle) cause product failure and serious reduction production efficiency and increase production cost, product shockproof effect is poor, is easily taken out of by briquetting and cause contacting failure state time stressed outside rubber-insulated wire.Product is large because taking pcb board position when using drawing structure to use simultaneously, makes the design of pcb board bring great inconvenience.And front cover-lifting type structure connects under only having, use compatible low.Caused product contact to depart from cannot contact with rubber-insulated wire as front flip when bearing rubber-insulated wire overbending will flick, product cannot signal transmission and power supply etc. cause being in failure state.Meanwhile, current product structure only has single-contact simultaneously compatiblely cannot use multiple rubber-insulated wire, makes client add degree of difficulty in the management and control of material, adds cost.
FPC connector of the prior art, comprise main body, flip, terminal, flip is a lever construction, comprise flip arm of force portion, with flip contact site, flip fulcrum is provided with between described flip arm of force portion and flip contact site, described terminal is that a lever construction is arranged in main body, terminal is generally fixed in the terminal groove in main body by the mode of buckle, terminal comprises terminal arm of force portion and terminal fitting portion, terminal fulcrum is provided with between terminal arm of force portion and terminal fitting portion, flip contact site applies pressure by flip fulcrum to terminal arm of force portion and the spacing of terminal fitting portion is reduced, rubber-insulated wire and product is made to keep engaging and conducting state, but such structural termination is after closing, the terminals being squeezed in rubber-insulated wire of terminal fitting portion rigidity centered by terminal fulcrum, its toughness is not enough, after installation repeatedly, terminal fulcrum portion produces metal fatigue, the thrust to rubber-insulated wire of terminal fitting portion reduces, flip contact site impulse stroke needs increase could meet terminal fixing FPC, but, because the impulse stroke of flip contact site is fixed, both now can be caused to coordinate and to occur disconnected button.
Utility model content
Based on the problems referred to above, the utility model object is to provide a kind of FPC connector, and can make terminal and PFC after long dismounting, both still realize stable electrical connection.
For above problem, provide following technical scheme: a kind of FPC connector, comprise main body, flip and terminal, described flip is movably hinged in main body, and comprises flip arm of force portion, flip contact site and the flip fulcrum between the above two; In the terminal groove that described terminal is arranged on the correspondence in main body and the linking arm comprising upper terminal, lower terminal and be connected between the two, the both sides that described upper terminal is positioned at linking arm comprise the terminal arm of force portion corresponding with flip contact site respectively and coordinate with FPC the chimeric arm of upper terminal fixed; Described lower terminal is respectively lower terminal in the both sides being positioned at linking arm and is fitted together to arm and connecting portion, and described upper terminal is fitted together to the end that arm and lower terminal be fitted together to arm and arranges the chimeric end of upper terminal and the chimeric end of lower terminal respectively; It is characterized in that: described lower terminal is butted on the bottom of terminal groove and is fitted together to arm by lower terminal and coordinates fixing in terminal groove; Described upper terminal and terminal groove top clearance are arranged, and described linking arm is the flexure strip of arcuate structure, and the opening of arcuate structure is right against flip.
The utility model is also set to further, and position corresponding with linking arm on described upper terminal arranges the projection being butted on terminal groove top.
The utility model is also set to further, and the end that described lower terminal is fitted together to arm also arranges inserted terminal, is formed and coordinate fixing inserting groove with main body between described inserted terminal end chimeric with lower terminal, main body is arranged and coordinates fixing Plug Division with inserting groove.
The utility model is also set to further, and described projection arranges boss structure respectively relative to the both sides of the sidewall of terminal groove.
The beneficial effects of the utility model: linking arm is the arcuate structure flexure strip that opening is right against flip, after flip contact site and terminal arm of force portion remove and coordinate, the terminal arm of force portion of upper terminal and upper terminal can be made to be fitted together to arm there is better resilience effect, being convenient to extracting of FPC and fixing again to FPC, solving upper terminal hypodynamic problem of its resilience when coordinating flip in prior art; Protruding setting can play resiliency supported effect to upper terminal, this outer lug arranges boss structure, terminal can be made to make itself and terminal groove have larger confining force while thickness is as far as possible thin, be convenient to the swing of upper terminal relative to projection, thus realize being fixed FPC.
