Description

The CD testing agency of suction type CD player

Technical field

The utility model relates to the CD player field, specifically is meant a kind of CD testing agency of suction type CD player.

Background technology

At present, suction type CD player CD detection mode generally has two kinds: a kind of is photocell detection, and another kind is that mechanical switch detects.Photocell detection mode wherein: need upper and lower sensor board, power valve and receiving tube, cost is high and have the possibility of judging by accident, and photoelectric tube is influenced by the light of some special angle of external environment also, can influence photoelectric tube induction CD and cause erroneous judgement when some angle light is too strong; The detection mode of mechanical switch mainly is made of left dish arm, right dish arm, switch and pcb board, and relatively the photo-electric detection is reliable relatively, and cost is also lower slightly.The utility model belongs to a kind of of mechanical detection.

The mechanical detection mode is very high because of the requirement of switch being stirred power, and the price higher spring loaded switch that compares is all adopted in general design, to reduce the triggering power of switch.The utility model adopts common leaf switch.

The utility model content

At above-mentioned defective, the technical matters that the utility model solves is to provide a kind of CD testing agency of suction type CD player, common blade switch and relevant dish arm configuration are improved, realize video disc turnover storehouse measuring ability by replacing spring loaded switch after improving, greatly reduce cost.

The CD testing agency of the suction type CD player that the utility model provides comprises switch, dish arm, and described switch is a leaf switch, and the movable contact spring of described leaf switch is provided with guide part, and described dish arm is provided with the briquetting that promotes described guide part.

Preferably, described dish arm comprises left dish arm and right dish arm, and described left dish arm is provided with the briquetting that promotes described guide part.

Preferably, described dish arm comprises left dish arm and right dish arm, and described right dish arm is provided with the briquetting that promotes described guide part.

Preferably, the guide part of described leaf switch movable contact spring is the boss of arc-shaped structure.

Preferably, described guide part is the boss of arc-shaped structure.

The CD testing agency of the suction type CD player that the utility model provides, the movable contact spring of leaf switch is provided with guide part, and on the dish arm briquetting is set correspondingly, when the briquetting of dish arm promotes the movable contact spring of leaf switch, guide part on the movable contact spring play the guiding role, the leaf switch conducting can reduce the power of toggle switch like this, reaches to use the detector switch purpose of leaf switch at a low price as suction type CD player.Under the situation of assurance function, reduced cost.

Compared with prior art, has following beneficial effect:, reduced production cost with the switch of leaf switch as CD testing agency.

Fig. 1 is for comprising the structural representation of the mainframe of CD testing agency in the utility model embodiment suction type CD player;

Fig. 2 is the enlarged drawing of partial structurtes among Fig. 1;

Fig. 3 is the structural representation of leaf switch among Fig. 1;

Fig. 4 is the structural representation of right dish arm among Fig. 1.

Embodiment

For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 1 is for comprising the structural representation of the mainframe of CD testing agency in the utility model embodiment suction type CD player; Fig. 2 is the enlarged drawing of partial structurtes among Fig. 1; Fig. 3 is the structural representation of leaf switch among Fig. 1; Fig. 4 is the structural representation of right dish arm among Fig. 1.

The CD testing agency of the suction type CD player that the utility model provides, be installed on the mainframe S, comprise leaf switch 3, dish arm, dish arm gear 5 and dish arm spring 4 and pcb board 1, the movable contact spring 32 of leaf switch 3 is provided with guide part 31, and guide part 31 is the boss of arc-shaped structure; The dish arm is provided with the briquetting 21 that promotes boss 31.The dish arm comprises left dish arm 6 and right dish arm 2, in left dish arm 6, the right dish arm 2 any one dish arm be provided with briquetting 21 all can, it is that example is done explanation that present embodiment is provided with the briquetting 21 that promotes boss 31 with right dish arm 2.

The CD testing agency of the suction type CD player that the utility model provides, the movable contact spring 32 of leaf switch 3 is provided with boss 31, and on the right dish arm 2 briquetting 21 is set correspondingly, when CD gulps down into or spues, the briquetting 21 of right dish arm 2 promotes the movable contact spring 32 of leaf switch 3, boss 31 on the movable contact spring 32 play the guiding role, the movable contact spring 32 of leaf switch 3 contacts with static contact 33, leaf switch 3 conductings can realize like this with the detector switch of leaf switch 3 at a low price as suction type CD player.

Because it is the leaf switch unit price is the lower switch of price in the switch industry, also lower with the cost of the CD testing agency of this switch.

Certainly; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
