Abstract
The utility model discloses a power socket and switch installation structure of a front projector, which comprises a case, a circuit board in the case, and a power socket and a power switch which are arranged on the case, wherein the power socket, the power switch and the circuit board are electrically connected, the power socket is fixedly connected with the power switch into a whole power supply part, and the power supply part is electrically connected with the circuit board. Through connecting the power socket and the power switch into a whole power supply part, not only the case design is simplified, and the incidence rate of the connection between the power socket and the power switch is reduced, but also the assembly of the whole front projector is facilitated.
Description
Technical field
The utility model relates to a kind of front projection machine, especially a kind of front projection machine supply socket and switch installing structure.
Background technology
Front projection machine owing to have can go out at less space inner projection bigger picture, volume little, be convenient to move and advantages such as placement, in daily study of today, work and life, use more and more widely.The power switch of front projection machine is connected with supply socket, the general pin that adopts is welded to connect between its supply socket and its printed circuit board, because supply socket often plugs plug, therefore supply socket and power switch all need to fix with casing, avoid contact engaging and separating force to make connecting the pin sealing-off or twist off.Existing front projection machine casing has box-like casing to add the structure of plane loam cake, also has U type base plate to add the structure that the back terminal strip adds L shaped upper cover plate again.In the casing is circuit board, and circuit board generally is fixedly connected on the base plate, is electrically connected between power switch, supply socket and the circuit board.The power switch of existing front projection machine, supply socket are individual devices separately, and when structural design, casing just need be distinguished Design Orientation and fixed sturcture to power switch, supply socket, and, neither be very convenient when the assembling casing.
The utility model content
In order to overcome the deficiency of existing front projection machine supply socket and switch installing structure assembling inconvenience, technical problem to be solved in the utility model provides a kind of front projection machine supply socket and switch installing structure easy to assembly.
The technical scheme that its technical matters that solves the utility model adopts is: front projection machine supply socket and switch installing structure, comprise the circuit board in casing, the casing, and be arranged on supply socket and power switch on the casing, supply socket, power switch are electrically connected with circuit board, the affixed as a whole power part spare of described supply socket and power switch, this power part spare is electrically connected with circuit board.
The beneficial effects of the utility model are: by with supply socket and the affixed as a whole power part spare of power switch, both simplified the casing design, and reduced the incidence that connects fault between supply socket and the power switch, and also made things convenient for final assembly.
Description of drawings
Fig. 1 is an assembling synoptic diagram of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the C-C cut-open view of Fig. 2.
Be labeled as circuit board 1, power part spare 2, base plate 3, back terminal strip 4, supply socket 21, power switch 22, edge 23, spacing muscle 31, through hole 40, draw-in groove 41 among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As Fig. 1, Fig. 2 and shown in Figure 3, front projection machine supply socket of the present utility model and switch installing structure, comprise the circuit board 1 in casing, the casing, and be arranged on supply socket 21 and power switch 22 on the casing, supply socket 21, power switch 22 are electrically connected with circuit board 1, described supply socket 21 and power switch 22 affixed as a whole power part spares 2, this power part spare 2 is electrically connected with circuit board 1.Behind the power part spare 2 of supply socket 21, power switch 22 being made of one, on structure, no longer need location and the fixed sturcture that is complementary with supply socket 21, power switch 22 is set respectively, and only need a unified location and fixed sturcture just passable; From assembling, generally be to realize being electrically connected between power part spare 2 and the circuit board 1 with pin, saved supply socket 21 and power switch 22 interconnective number of assembling steps, also simplified and casing between locate the operation of assembling; From reliability, also reduced the incidence that connects fault between supply socket 21 and the power switch 22.
As Fig. 1, Fig. 2 and shown in Figure 3, the general electric component of assembling earlier when considering final assembly, refill the distribution structure parts, therefore described casing generally should comprise base plate 3 and the back terminal strip 4 that is connected with base plate 3, described circuit board 1 is arranged on the base plate 3, and described power part spare 2 is by 31 supportings of the spacing muscle on the base plate 3, and conveniently the electric parts 2 of butt joint carry out coarse positioning in assembling, back terminal strip 4 is provided with the through hole 40 suitable with described power part spare 2, is convenient to assemble the power supply control operation of back to complete machine.
As Fig. 1, Fig. 2 and shown in Figure 3, adopt plug-in type to connect between described base plate 3 and the back terminal strip 4, described power part spare 2 is provided with edge 23, and described back terminal strip 4 is provided with the draw-in groove 41 that is complementary with described edge 23.The process that back terminal strip 4 is plugged on the base plate 3 also just makes described edge 23 and draw-in groove 41 structures that power part spare 2 is stuck on the terminal strip 4 of back simultaneously, easy to assembly, and in the time of can correcting power part spare 2 assembling its with circuit board 1 between to be connected the welding of pin crooked, even can guarantee also that power part spare 2 is stressed in the plug process of power lead does not shake yet, guarantee to be electrically connected reliably between pin and the circuit board 2.Described base plate 3 and the back plug-in type between the terminal strip 4 connects and can adopt the form that is provided with on the biside plate of base plate 3 with the suitable vertical slot of back terminal strip 4 limit portion thickness to realize.
Described draw-in groove 41 should be positioned at the edge of described through hole 40, plays the effect of local reinforcement simultaneously, and is beneficial to the local strength of fenestration product, prevents repeatedly the local damage of contact engaging and separating force to back terminal strip 4.
