Abstract

The utility model provides an FPC patch cord, relating to the printed circuit board test field and in particular to an FPC (Flexible Printed Circuit) board used for test. The FPC patch cord comprises a plurality of BTB connector male seats and at least one BTB connector female seat; the plurality of BTB connector male seats are in vertical parallel connection; a BTB connector male seat adjacent with the BTB connector female seat is in vertical parallel connection with a BTB connector male seat; a parallel circuit between two adjacent BTB connector male seats is provided with a transverse pressing line unit used for labeling snip or tear; two adjacent BTB connector male seats are not disconnected and do not expose copper. The FPC patch cord prolongs the service life of the FPC patch cord and reduces test costs.

Description

A kind of FPC patchcord

Technical field

The utility model relates to the printed circuit board field tests, particularly for the FPC flexible circuit board of testing.

Background technology

Grow on trees in the society now existence of precise electronic product, the precise treatment of interruption, miniaturization are impelling chip and device also constantly to the miniaturization development, and the BTB connector is because its ultra-thin characteristic makes it obtain using widely.

In present production procedure, the hard circuit board is called for short the PCB paster, after the welding, just need not carry out function, performance test to it before having the relevant electronic unit of assembling, therefore needs to make special testing tool and finishes test assignment.Referring to shown in Figure 1, if PCBA goes up paster BTB connector female seat 1 is arranged, SMT quality, function for test b TB connector female seat 1 itself and interlock circuit need be connected the electrical testing that works of going forward side by side with PCBA1 with corresponding electronic unit 11.But electronic unit 11 is compact with the assembling of PCBA1, be not easy to operation, therefore, need by FPC patchcord 7 PCBA9 to be connected with corresponding electronic unit 11, and with the increase operating space, the reduction operation easier.But because plug repeatedly, the connector male seat of BTB can often be damaged (the connector male seat plug number of times of BTB is about 200 times), in case BTB connector male seat is damaged, that whole piece FPC patchcord will be scrapped, cause the FPC patchcord life-span shorter, can cause testing cost too high thus.

Summary of the invention

In view of this, in order to solve the deficiencies in the prior art, the utility model provides a kind of FPC patchcord.

The technical scheme of the utility model FPC patchcord is such:

A kind of FPC patchcord, comprise: a plurality of BTB connector male seats and at least one BTB connector female seat, vertically be connected in parallel between a plurality of BTB connector male seats, and the BTB connector male seat adjacent with BTB connector female seat and BTB connector male seat also vertically are connected in parallel, parallel line between two adjacent BTB connector male seats is provided for marking the horizontal line ball unit of cutting off or tearing, and non-opening circuit between two adjacent BTB connector male seats, and do not reveal copper.

Preferably, a plurality of BTB connector male seats are arranged on the flexible circuit board, and make between a plurality of BTB connector male seats all equidistant parallel arranged.

Preferably, BTB connector female seat is arranged on the flexible circuit board.

Preferably, laterally the line ball unit has at least one indent.

Further preferably, laterally the line ball unit have position correspondence and length unanimity one on indent and indent once.

Further preferably, indent is chamfered groove.

Preferably, laterally the line ball unit becomes the vertical direction crosscut with BTB connector male seat with the vertical closure of BTB connector female seat.

Compared with prior art, the utility model has the following advantages at least:

1, is provided with the BTB connector male seat of a plurality of parallel connections a FPC patchcord, even if a BTB connector male seat is damaged in the time of can't using, can use next BTB connector male seat to connect printed board to be tested, thereby prolonged the useful life of FPC patchcord greatly, and reduced testing cost.

2, owing to the FPC patchcord raising in useful life, can reduce the human input that frock is safeguarded on the one hand; Can reduce the situation that test station in the frock maintenance process is in halted state on the other hand, thereby reduce the influence to system test efficient.

Fig. 2 illustrates the structural representation of a kind of embodiment of FPC patchcord of the present utility model;

Shown in Fig. 3 a is the lateral plan of FPC patchcord shown in Figure 2;

Shown in Fig. 3 b is the partial enlarged drawing of FPC patchcord shown in Fig. 3 a.

Embodiment

In order to make the relevant technical staff in the field understand the technical solution of the utility model better, accompanying drawing below in conjunction with the utility model execution mode, technical scheme in the utility model execution mode is clearly and completely described, obviously, described execution mode only is the utility model preferred implementation, rather than whole execution modes.

In order to solve short problem of existing FPC patchcord life-span, a kind of execution mode that the utility model provides be by arrange simultaneously at the end in the single FPC patchcord a plurality of for the BTB connector male seat (2 corresponding with BTB connector female seat 1 on the PCB to be measured, 3,4,5,6), the other end also arranges one and goes up identical BTB connector female seat 8 with PCBA9, in FPC patchcord 7 a plurality of BTB connector male seats (2 are set, 3,4,5,6) time, with BTB connector male seat (2,3,4,5,6) carry out parallel arranged, with parallel arranged these 5 BTB connector male seats being set is that example describes, with reference to shown in Figure 2, inwardly parallel arranged laying successively of an end from FPC patchcord 7, two adjacent BTB connector male seats, as BTB connector male seat 2 and BTB connector male seat 3, BTB connector male seat 3 and BTB connector male seat 4, BTB connector male seat 4 and BTB connector male seat 5, BTB connector male seat 5 and BTB connector male seat 6, the pin that interface definition is identical connects by lead-in wire is corresponding, realizes BTB connector male seat 2 thus, 3,4,5,6 parallel connection.Then, to be positioned at the most inboard BTB connector male seat 6 by the inside cabling 12 of FPC patchcord 7 each pin corresponding couple together identical with being positioned at FPC other end BTB connector female seat 8 interface definitions, realize the signal communication between BTB connector male seat (2,3,4,5,6) and the BTB connector female seat 8 thus.

By single BTB connector male seat in the FPC patchcord 7 is increased to two rows, three row or more rows, after being positioned at the outermost first row BTB connector male seat inefficacy, can utilize instruments such as scissors along the line ball 10 that is attached in the FPC patchcord 7 BTB connector male seat 2 to be cut, then the second row BTB connector male seat 3 then can be connected to PCBA to be measured and go up the continuation use as the new end of FPC patchcord 7.Can be to extend to original twice, three times or more in useful life of whole piece FPC patchcord in this way, thereby reduce the testing cost of FPC patchcord 7 significantly.

For make instrument such as scissors more convenient, BTB connector male seat 2 cut off break away from the FPC patchcord more easily, perhaps not by also can be more convenient under the situation of instrument, more easily BTB connector male seat is torn off the FPC patchcord, line ball unit 10 is set to have last indent 101 and the following indent 102 at inclination angle, shown in Fig. 3 a and Fig. 3 b.

Present embodiment has the following advantages at least as preferred embodiment:

Below only expressed preferred implementation of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
