Abstract

The utility model relates to an FPC (Flexible Printed Circuit) connector, which comprises a housing, a plurality of terminals fixed on the housing side by side, a cover and two pegs. The housing is provided with a plug-in face for the FPC to plug, the first end (front end) of each terminal is provided with a contact and faces to the side where the plug-in face is located and the second end (rear end) of each terminal is provided with a half-open axial notch, and the cover can be arranged in the half-open axial notch of the second end in an over-turning manner and is located on the housing on the side opposite to the plug-in face. Since a whistle-shaped rotating shaft is arranged in the FPC connector, and during rotation process, the cover orderly rotates along the axle center of the rotating shaft, the bottom strength of the rotating shaft is enhanced structurally; through arranging a shock-proof lock table, after the cover is pressed down to a complete state, the rotating shaft of the cover is locked basically; through arranging a two-contact convex point structure, both the pull-out force and the contact reliability of the FPC are improved; and through adopting a retaining suspension table arranged at the head parts of the pegs, convex pillars on two sides of the cover are prevented from exiting backwards.

Description

FPC connector

Technical field

The utility model relates to a kind of FPC connector, relates in particular to lift the formula FPC connector after inserting before a kind of.

Background technology

FPC connector; Be FPC Connector; It is the abbreviation of Flexible Printed Circuit Connector; The Chinese implication is Fcp connector (FPC/bus bar connector), and it mainly is to be used for all kinds of civilian mobile communication equipments and all kinds of individual terminal devices (like mobile phone, PDA, GPS, MP3/MP4, digital camera, hand-held game machine, all kinds of CD players etc.), is to realize being connected between each functional module of this type of device interior or with the signal of external equipment or transmitting; And equipment and effects such as being communicated with of power supply or signal source, finally realize the connectivity scenario of device power supply (DPS)/signal.

Receive market clouts such as 3G mobile and smart mobile phone, ultrathin notebook PC demand, the current developing direction of FPC connector is: low clearance, little pitch, easy to operate, multi-functional, good Electro Magnetic Compatibility, and standardized size.

Present stage, lift the formula FPC connector after preceding the inserting that the connector industry is produced and generally comprise: stator 91, main body 92, terminal 93 and flip 94 (shown in Figure 1A ~ 1E).

Wherein, The rotating shaft 941 of flip 94 is the cylindrical body structure; Its cross section is rectangle or approximate rectangular (shown in Figure 1A and Figure 1B), and there is following shortcoming in this conventional structure: 1. rotating shaft " axle center " is not clear, causes flip when rotating, to produce axial translation or turns to lift problem such as have some setbacks; 2. rotating shaft " foundation " shakiness refers to rotating shaft bottom or basically identical consistent with the top thickness, and rotating shaft causes product function to lose depositing when receiving eversion pressure the bottom easy fracture or slight crack occurring.

In addition; Upper arm second end 931 that lifts formula FPC connector terminal 93 after inserting before the tradition is straight shape regular texture (shown in Figure 1B and Fig. 1 C); There is following shortcoming in this conventional structure: flip fastens and is in when working in the vibration environment that jolts; The flip problem of upspringing automatically very easily occurs, cause the connector function forfeiture.

Moreover; Lift formula FPC connector terminal 93 underarms first end 932 after inserting before the tradition and be single contact salient point structure (shown in Figure 1B); There is following shortcoming: 1.FFC in this conventional structure, and (flexible flat cable: flexible flat cable) withdrawal force is less, especially inserts FPC socket travel at FFC and is prone to more in short-term be drawn out.2. single contact point design contact reliability is lower.

Also have; Lift formula FPC connector stator head 911 after inserting before the tradition and be straight shape structure; It is up and down to be used for limiting cover-lifting 94 both sides projections 942, prevents that flip 94 from coming off (shown in Fig. 1 D) to the top, and there is following shortcoming in this conventional structure: though but the stator head 911 basic fixed flips 94 of straight shape structure; Prevent that it from coming off to the top; But flip 94 is in rotating process, stator 91 from left and right directions with flip 94 restrictions, therefore still have flip 94 hidden danger (shown in Fig. 1 E) that drops.
