The sliding part is provided with a peripheral wall in a group manner which can accommodate the spring. The peripheral wall can limit all radial motions of the spring inside. Through the limiting of the peripheral wall, the slide switch can better control the operating process of the spring and improve the operating stability.

Description

Slide switch

[technical field]

The utility model relates to a kind of switch, refers in particular to a kind of slide switch that is used on the electronic product equipment.

[background technology]

Slide switch is a kind of by its moving part is carried out slippage, thereby realizes the break-make of internal circuit and the electronic component of conversion, because easy and simple to handle, process is advantage such as realizations easily, and application is very widely arranged in electronic product equipment.Chinese patent is announced No. 2916893 and has promptly been disclosed a kind of this type of slide switch, and it comprises the insulating body that is provided with the fixed terminal group, movably is assembled in insulating body and be provided with control lever, spring and the lid that coats the aforementioned dielectric body of interlock terminal.By push lever, can change the contact condition of moved end and fixed terminal group, thereby realize the break-make and the conversion of circuit.

Yet; spring can shrink by pressurized in the forward pushing course; then can be after the distortion to the coating lid one side warpage of position limitation protection weakness; in the course of time; friction between spring that this warpage produces and coating lid then can influence the operate as normal of slide switch so that reduce the life-span of slide switch; and when being subjected to bigger pressurized external force when spring, the side force that warpage produces even can squeeze and hold the coating lid works the mischief to internal circuit element even operator.

Given this, be necessary to provide a kind of improved slide switch in fact, to overcome the defective of above-mentioned slide switch.

[utility model content]

Technical problem to be solved in the utility model provides a kind of slide switch that can improve the spring job stability.

For solving the problems of the technologies described above, the utility model provides a kind of slide switch, it comprises diapire with lengthwise and first end wall that extends upward from the diapire longitudinal ends and the insulating body of second end wall, be mounted on the fixed terminal group on the insulating body, be mounted on space that described diapire and end walls surround and can be along the reciprocating sliding part of longitudinally, be mounted on sliding part and selectively with moved end of fixed terminal set of contact, being mounted on insulating body first end wall also can be along the flexible spiral spring of longitudinally, and be held in lid on the insulating body, it is characterized in that: group is provided with the perisporium of putting spring on the described sliding part, and described perisporium can carry out the spacing of whole radial motions to the spring that is placed in wherein.

Compared with prior art, the utility model has the following advantages at least: be mounted on the perisporium on the sliding part, can be when sliding part be subjected to the external force extrusion spring, finish spring is carried out radially spacing action, with being contained in spring warpage in the perisporium is stabilized among a small circle, be revealed in the outer spring of perisporium then because the restriction of perisporium makes movable length become limited, so, control its warpage amplitude equally effectively, reduced the unsteadiness of the process done.

Fig. 2 is the three-dimensional exploded view of the utility model slide switch;

Fig. 3 is the exploded view behind the utility model slide switch lid and the sliding part pressurized.

[embodiment]

Please refer to Fig. 1 to shown in Figure 3, the utility model slide switch 100 comprises insulating body 1, be shaped in fixed terminal group 2 in the insulating body 1, be mounted on sliding part 3 on the insulating body 1, be mounted on moved end 4 of sliding part 3, the lid 6 that is mounted on the spring 5 of insulating body 1 and is held in insulating body 1.

Described insulating body 1 is one-body molded fixed terminal group 2, comprise the diapire 11 of lengthwise and from upwardly extending first end wall 12 of 11 liang of longitudinal ends of diapire and second end wall 13, described sliding part 3 promptly is located at described diapire 11 and end walls (12,13) also can be in the sliding space 14 that is enclosed to form in end walls (12,13) reciprocating motion between, diapire 11 middle parts in the last rib 15 of lengthwise that convexes with to guide described sliding part 3 in end walls (12,13) motion between, moved end 4 that group is established on the sliding part 3 then can follow the motion process of sliding part 3 selectively to contact with fixed terminal group 2, to reach the function of switch or conversion.

Described spring 5 is a helical form, being arranged at sliding space 14 interior also ends is resisted against on first end wall 12, described diapire 11 is provided with the reference column 16 of keeping out spring 5 other ends in the position male of corresponding spring 5 other ends, to realize that sliding part 3 effects are preceding the preliminary of spring 5 fixed, but then be installed with the perisporium 31 of putting spring 5 on the sliding part 3, carry out spacing with whole radial motions to spring 5, make the motion of the spring 5 enter sliding part 3 by limit in the scope of perisporium 31, to prevent that spring 5 whole warpages frictions are to the generation that damages.Perisporium 31 is non-closed circular, is being provided with first fluting 32 near the position of diapire 11 to cooperate the slip of leading of rib 15 on the aforementioned diapire 11; Simultaneously also be concaved with second fluting 33 in the side away from diapire 11, this second fluting 33 is to form because of reducing slide switch 100 whole heights, precisely because still be provided with spacing top margin 34, in conjunction with the remainder of perisporium 31, can carry out all radially spacing to spring 5.At sliding part 3 when first end wall, 12 directions are slided, described perisporium 31 also begins spring 5 wherein ccontaining, and increase gradually along with sliding part 3 range of movement, the distortion of spring 5 increases gradually, described perisporium 31 is also little by little close to first end wall 12, restricted spring 5 more, thereby guarantee the stability of spring 5 operating states.

Described slide switch 100 also includes a lid 6 that can be snapped in insulating body 1, described lid 6 is made by sheet metal, form an elastic card 61 on the lid 6, then be provided with the locating convex block 36 that matches with this elastic card 61 on the sliding part 3, can when sliding part 3 moves to ad-hoc location, realize buckle and indicative function.

The execution mode that the above only provides for the utility model, it is not whole or unique execution mode, every those of ordinary skills take the variation of any equivalence to technical solutions of the utility model by reading the utility model specification, all should be claim of the present utility model and contain.
