Abstract
The utility model discloses a kind of stable type PCB connecting plate, comprise rectangle connecting plate, be fixed on the pcb board of these rectangle connecting plate central authorities, and the slot be arranged on this rectangle connecting plate corner, described slot comprises the upper slot of at least two of being positioned on described rectangle connecting plate upper surface, and is positioned at least two lower slots on described rectangle connecting plate lower surface; Described upper slot is identical with lower slot structure, and its cross section is U-shaped, and all upper slots and lower slot are interspersed, and the horizontal range r between adjacent upper slot and lower slot is 0.1 ~ 0.3mm.The utility model structure is simple, and cost is low, and practical value is high, is applicable to very much applying.
Description
Technical field
The utility model relates to a kind of pcb board.
Background technology
Pcb board is printed wiring board, is one of vitals of electronic product, and all electronic devices and components all must rely on pcb board just can carry out installing, locating, and then form operable electronic circuit.
Patent 201420249711.8 discloses a kind of PCB connecting plate, for solving existing pcb board due to the problem easily fractureed in the transportation of V-CUT angle and thickness arrival lack of standardization or after point plate, burr is large, but, because this technology is only be arranged on connecting plate by slot, do not tackle the problem at its root, the root of its key problem still exists, i.e. V-CUT angle and thickness Problem, therefore, although this patent can play certain effect, but still not ideal enough.
Utility model content
The purpose of this utility model is to provide a kind of stable type PCB connecting plate, fundamentally solve in prior art exist because of the problem easily fractureed in V-CUT angle and the thickness transportation brought lack of standardization and after point plate, burr is large.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Stable type PCB connecting plate, comprise rectangle connecting plate, be fixed on the pcb board of these rectangle connecting plate central authorities, and the slot be arranged on this rectangle connecting plate corner, described slot comprises the upper slot of at least two of being positioned on described rectangle connecting plate upper surface, and is positioned at least two lower slots on described rectangle connecting plate lower surface; Described upper slot is identical with lower slot structure, and its cross section is U-shaped, and all upper slots and lower slot are interspersed, and the horizontal range r between adjacent upper slot and lower slot is 0.1 ~ 0.3mm.
Further, the rectangle connecting plate being positioned at described pcb board outside is evenly distributed with at least four location holes.
Further, the thickness of described rectangle connecting plate is 1/2 of described pcb board thickness.
Preferably, the horizontal range between adjacent upper slot and lower slot is 0.2mm.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model is based on technology disclosed in patent 201420249711.8, improve dexterously, the V-structure of slot is improved to U-shaped structure, thus changed stress point into stress surface, according to mechanics principle, identical External Force Acting is comparatively concentrated and is acted on a bit more difficult fractureing on a face, so just greatly can improve stable type, fundamentally solve in V-CUT angle and the thickness transportation brought lack of standardization easily fracture, the problems such as burr is large after point plate, practical value promotes greatly.
(2) the utility model offers multiple slot be interspersed respectively in the upper and lower surface of connecting plate, so, just can provide multiple points of plate points, under the prerequisite improving stability in transportation, for a point plate provides larger convenience.
(3) the utility model changes the habitual thinking of conventional art, by small and exquisite design, namely solves the technical problem of the medium-term and long-term existence of prior art, opens brand-new mentality of designing for PCB making sheet industry.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is side schematic view of the present utility model.
Fig. 3 is the enlarged diagram at A position in Fig. 1.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
1-PCB plate, 2-rectangle connecting plate, the upper slot of 3-, slot under 4-, 5-location hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and execution mode of the present utility model includes but not limited to the following example.
Embodiment
As shown in FIG. 1 to 3, the utility model is the improvement carried out in the technical foundation of patent 201420249711.8, and its primary structure comprises pcb board and rectangle connecting plate; Pcb board is fixed on the central authorities of rectangle connecting plate, and slot is arranged on the corner of rectangle connecting plate.Specifically, described slot comprises the upper slot of at least two of being positioned on described rectangle connecting plate upper surface, and is positioned at least two lower slots on described rectangle connecting plate lower surface; Described upper slot is identical with lower slot structure, and its cross section is U-shaped, and all upper slots and lower slot are interspersed, and the horizontal range r between adjacent upper slot and lower slot is 0.1 ~ 0.3mm.By controlling the horizontal range between upper slot and lower slot, effectively can control the closeness of slot, and then accurately control the difficulty of point plate, take into account integrally-built stability simultaneously, achieve many things at one stroke.
For the ease of the installation of pcb board, the rectangle connecting plate being positioned at described pcb board outside is evenly distributed with at least four location holes.
In order to guarantee the stability that pcb board is installed and reliability further, reduce the thickness of whole sheet material, avoid proposing larger requirement to installing space, the thickness of described rectangle connecting plate is 1/2 of described pcb board thickness simultaneously as far as possible.
Preferably, the horizontal range between adjacent upper slot and lower slot is 0.2mm.
The utility model is by a little improvement, and fundamentally final result V-CUT angle and the thickness frangibility brought lack of standardization and the problem such as burr is large, achieve multiple technique effect simultaneously, have very high practical value.
Above-described embodiment is only preferred embodiment of the present utility model; restriction not to the utility model protection range; in every case design principle of the present utility model being adopted, and the change carried out non-creativeness work on this basis and make, all should belong within protection range of the present utility model.
