Abstract

The invention discloses a soft circuit board connector which can realize more stitches and comprises an insulating base body, a cover shell, a conductive terminal group and a base. The spacing distance among conductive terminals of the conductive terminal group adopts a narrow space which is not greater than 0.45mm. A front and back placement structure is adopted by SME (surface mounted technology) stitches at both poles of the conductive terminal. According to the scheme, the connector can be provided with as much as 128 stitches, and the number of the connectors used by clients is greatly decreased, therefore, the area space for a PCB (printed circuit board) is saved for clients, the production cost is reduced, and high production efficiency is achieved.

Description

A kind of flexible circuitry connector for substrate

Technical field

The present invention relates to the connector technique field, specifically is a kind of flexible circuitry connector for substrate.

Background technology

Growing along with electronic technology; The household electrical appliance technology also be development rapidly, also got into the liquid crystal epoch like TV, and the direction of development except ultra clear; More need ultra-thin ultra wide; This also is more little good more to the parts in the TV such as PCB (printed circuit board (PCB)), electronic devices and components, LCD (liquid crystal is looked plate) thickness requirement, and the interconnection between PCB and the LCD generally is to realize that through connector and with the cable that connector connects the 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 both at home and abroad at present is exactly FPC (flat flexible cable abbreviation 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 the flexible circuitry connector for substrate.The general stitch of flexible circuitry connector for substrate 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.

Summary of the invention

To the disappearance that above-mentioned prior art exists, the present invention aims to provide a kind of more improved flexible circuitry connector for substrate of spininess pin of realizing.

For realizing this technical purpose; Scheme of the present invention is: a kind of flexible circuitry connector for substrate; Comprise insulating base frame, lid shell, conducting terminal group and base portion; It is characterized in that the spacing between the conducting terminal of said conducting terminal group adopts the thin space that is no more than 0.45mm, and said conducting terminal the two poles of the earth SMT pin adopts the front and back installing structure.

As improvement, said 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 said flip and each conductor terminal tails is the flip cam; At peak, the contact of terminal moves down said 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.

Adopt the flexible circuitry connector for substrate of present technique scheme, 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

Below in conjunction with accompanying drawing and embodiment the present invention is done further description.

Like Fig. 1, shown in 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, like 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 flexible circuitry connector for substrate 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 like short circuit, rosin joint etc.; Adopted installing structure before and after the two poles of the earth conductor terminal SMT pin in this execution mode, thereby made the SMT pin of each terminal and PCB PAD have bigger space to stop solder shorts, the area increasing soldering tin amount of PAD increases that to stop rosin joint bad.

The fixing that combines of FFC flat flexible rubber-insulated wire and flexible circuitry connector for substrate; It is the key factor of guaranteeing the conductor switching performance; Cause FFC to combine to get loose for eliminating product because of vibration or other factors, 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 with connector; 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.

Like Fig. 3 and Fig. 4, the present invention develops pressure type structure after the easy to operate flip, and the principle of design is to be a cam mechanism 3 through the position that flip 1 contacts with each conductor terminal tails 2; The both direction of cam has a difference in size, and notice is the pressure-lift lid up and down, makes conductor terminal and flip cam position that a size drop 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; The contact of terminal is at peak, thereby with the FFC rubber-insulated wire not conducting of certain clearance arranged.During like need FFC rubber-insulated wire and termination contact, as shown in Figure 4, only need flip is pressed down 90 degree, through flip cam position terminal tails is upwarped, thereby moving down, drive terminal head contact presses to the FFC rubber-insulated wire, lead terminal and the conducting of FFC rubber-insulated wire thereby make.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 is merely preferred embodiment of the present invention, and in order to restriction the present invention, every foundation technical spirit of the present invention all should not be included within the protection range of technical scheme of the present invention any modification, replacement and improvement that above embodiment did.
