Abstract

The utility model discloses a FPC connector capable of realizing more pins, which comprises an insulating seat, a casing, a conducting terminal group and a base. Narrower spacing less than 0.45mm is adopted among conducting terminals of the conducting terminal group, and two polar SMT pins of each conducting terminal are of a front-and-rear placement structure. The connector of the scheme can be provided with pins up to 128, users can use greatly reduced connectors after using the connector, and accordingly the connector saves PCB area space for the users, reduces production cost and can achieve production high efficiency.

Description

A kind of FPC connector

Technical field

The utility model design connector technique field specifically is a kind of FPC connector.

Background technology

Growing along with electronic technology, the household electrical appliance technology also is that development is rapid, also the liquid crystal epoch have been entered as TV, and the development direction except super clear, more need ultra-thin super wide, this is to parts in the TV such as PCB (printed circuit board (PCB)), electronic devices and components, LCD (liquid crystal is looked plate) thickness requirement also is the smaller the better, interconnection between PCB and the LCD generally is to realize by connector and with the cable that connector connects, components and parts between PCB and the LCD are numerous in addition, the signal cable quantity that requires also is corresponding increasing, ultra-thin for satisfying shape requirement, holding wire requires numerous particularity, and adopting maximum connectors at present both at home and abroad is exactly FPC (flat flexible cable is called for short FPC) connector.It is the switching performance quality-critical factor of inner LCD of decision TV and PCB components and parts, and this just requires us must design ultra-thin, spininess pin, reliably FPC connector.The general stitch of FPC connector in the market can only be accomplished at most below 50, is difficult to satisfy for the client saves the PCB area space requirement that reduces production costs.

The utility model content

At the disappearance that above-mentioned prior art exists, the utility model aims to provide a kind of more improved FPC connector of spininess pin that realizes.

For realizing this technical purpose, scheme of the present utility model is: a kind of FPC connector, comprise insulating base frame, lid shell, conducting terminal group and base portion, it is characterized in that, spacing between the conducting terminal of described conducting terminal group adopts the thin space that is no more than 0.45mm, and described conducting terminal the two poles of the earth SMT pin adopts the front and back installing structure.

As improvement, described insulating base frame double side wings is provided with the boss that is complementary with FFC flat flexible rubber-insulated wire bilateral groove.

As further improvement, device has flip on the insulating base frame, the contact site of described flip and each conductor terminal tails is the flip cam, described flip cam in the contact of flip terminal up the time at peak, the contact of terminal moves down when flip presses down, and the contact that presses down 90 terminals when spending in flip is depressed into minimum point.

Adopt the FPC connector of the technical program, can be provided with nearly 128 or more a plurality of stitch, the client for the client has saved the PCB area space, has reduced production cost, and can reach the high efficiency in the production using connector quantitatively to significantly reduce.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, 2, distance between each conducting terminal of connector is referred to as spacing, and the size of spacing has also determined the contour length of connector, as the connector of an identical number of poles, the big more profile of the spacing of conductor terminal must be long more, thereby have influence on the required area of the PCB that settles connector.In this this embodiment, adopt narrower 0.45mm spacing, thereby the contour length of the FPC connector of multipole number (conductor terminal) is shortened greatly.On the SMT welding procedure, the product of thin space often leans on too closely because of PCB PAD (eating the tin position) the two poles of the earth, and occur seriously bad as short circuit, rosin joint etc., adopted conductor terminal SMT pin front and back, the two poles of the earth installing structure in the present embodiment, thereby make the SMT pin of each terminal and PCB PAD have bigger space to stop solder shorts, the area of PAD strengthens soldering tin amount and increases that to stop rosin joint bad.

The fixing that combines of FFC flat flexible rubber-insulated wire and FPC connector, it is the key factor of guaranteeing the conductor switching performance, get loose because of vibration or other factors cause FFC to combine with connector for eliminating product, thereby influence properties of product, increase on a groove and the connector body bilateral by a boss at the rubber-insulated wire bilateral and buckle and cooperate for having designed in this this embodiment, thereby the FFC rubber-insulated wire can not got loose under the effect of external force easily, guarantee that rubber-insulated wire connects the contact conduction property.

As Fig. 3 and Fig. 4, the utility model is developed pressure type structure after the easy to operate flip, the principle of design is to be a cam mechanism 3 by the position that flip 1 contacts with each conductor terminal tails 2, the both direction of cam has a difference in size, notice is the pressure-lift lid up and down, make conductor terminal and flip cam position that a size drop be arranged, thereby the contact that drives the terminal head moves up and down, as when need not rubber-insulated wire 4 with termination contact, as shown in Figure 3, flip need not press down 90 degree, and the contact of terminal is at peak, thereby with the FFC rubber-insulated wire not conducting of certain clearance arranged.During as need FFC rubber-insulated wire and termination contact, as shown in Figure 4, only need flip is pressed down 90 degree, terminal tails is upwarped, press to the FFC rubber-insulated wire, lead terminal and the conducting of FFC rubber-insulated wire thereby make thereby drive terminal head contact moves down by flip cam position.At peak, the contact of terminal moves down the flip cam when flip presses down in the contact of flip terminal up the time, and the contact that presses down 90 terminals when spending in flip is depressed into minimum point.

The above; it only is preferred embodiment of the present utility model; in order to restriction the utility model, every foundation technical spirit of the present utility model all should not be included within the protection range of technical solutions of the utility model any modification, replacement and improvement that above embodiment did.
