Description
Technical field
The utility model relates to a kind of elastic piece structure of anti electromagnetic wave, and especially a kind of shell fragment that makes has preferable restoring force and level and smooth shift motion when pressing use, make shell fragment be easy to the elastic piece structure of moulding and manufacturing simultaneously.
Background technology
General known shell fragment can be mounted on the printed circuit board (PCB) as sealing guiding type surface adhering shell fragment, and this shell fragment comprises: can be for the construction section that is mounted on the printed circuit board (PCB); Be the elastic arm section that an angle is extended from this construction section one end; From the connecting section of this elastic arm section away from this construction section one end, this connecting section and construction section extend in the same way, and the direction that defines between this construction section and this connecting section is first direction, and vertically this first direction is a second direction; Away from first extension of this elastic arm Duan Yiduan, be formed with the lead segment of extending from this connecting section on this first extension along this first direction toward this construction section direction extension; Away from second extension of this elastic arm Duan Yiduan toward this connecting section direction extension, this second extension has the section of protruding out that can move in this lead segment from this construction section; By the elastic deformation of this elastic arm section, and the cooperating of this section of protruding out and this lead segment, guide this connecting section and move up, and limit the displacement of this connecting section on this second direction in this first party.
Though above-mentioned known " sealing guiding type surface adhering shell fragment " in when compression, is by the cooperating of the elastic deformation of elastic arm section and the section of protruding out and lead segment, and this connecting section moved up in this first party, and limit the displacement of connecting section on second direction.But because the summit between the section of protruding out and lead segment is lower, stroke is shorter, and both move when start along a straight line, therefore when the elastic deformation of elastic arm section, first extension then can contact in the junction of the construction section and second extension, causes the angle of compression limited.Moreover this shell fragment is constituted with primary clusterings such as construction section, elastic arm section, connecting section, first extension, lead segment, second extension and the sections of protruding out, and also needs the bending through many places therebetween, thereby it is complicated that this shell fragment is made.
The utility model content
The purpose of this utility model is to solve above-mentioned shortcoming, avoid defective to exist, cooperate the setting of base plate, swash plate and top board by the utility model elastic plate and the top arm of pulling, can make shell fragment when pressing use, have preferable restoring force and level and smooth shift motion, make shell fragment be easy to moulding and manufacturing simultaneously.
For achieving the above object, the elastic piece structure of anti electromagnetic wave of the present utility model, it offers through hole on base plate, and being inclined upwardly at an end of base plate has extended to form swash plate, offers spacing hole on swash plate; Be inclined upwardly toward the direction of swash plate at the other end of base plate and extend to form flexible plate, at the terminal of elastic plate and be parallel to the base plate direction and extended to form top board, has the top arm of pulling at the end of top board, the downward-sloping extension of arm of pulling of this top penetrates in the above-mentioned spacing hole, and the top arm end of pulling holds on the medial surface of base plate.
Preferably, be formed with the linkage section of circular arc between described base plate and described elastic plate and described base plate and the described swash plate respectively.
Preferably, described swash plate extends to the inboard of described shell fragment.
Preferably, described spacing hole is the closed rectangular opening.
Preferably, pull and are formed with the bending segment of circular arc between arm and described top board and the described elastic plate respectively in described top board and described top.
Preferably, the pull end of arm of described top upwards has been bent to form the section of turning up.

Embodiment
Relevant detailed description of the present utility model and technology contents, accompanying drawings is as follows, yet accompanying drawing reference only is provided and be used for the explanation, be not to be used for the utility model is limited.
Fig. 1 is the stereo appearance figure of the elastic piece structure of the utility model anti electromagnetic wave.As shown in Figure 1, the elastic piece structure of anti electromagnetic wave of the present utility model, it mainly comprises base plate 1, elastic plate 2 and top board 3, can make this shell fragment have preferable restoring force and level and smooth shift motion when pressing use, makes shell fragment be easy to moulding and manufacturing simultaneously.
The extension that is inclined upwardly of the direction of elastic plate 2 from the other end of base plate 1 toward swash plate 12, and be formed with second linkage section 21 of circular arc between elastic plate 2 and the base plate 1.
Fig. 2 and Fig. 3 are respectively user mode profile of the present utility model and actuator state profile of the present utility model.As shown in Figures 2 and 3, shell fragment of the present utility model can be arranged on the circuit board 4, directly be coated with sticker 41 in the through hole 11 of shell fragment base plate 1, and correspondence is set on the circuit board 4.So, can allow the user be easy to coating and install, and can not allow the user that base plate 1 and top board 3 the two generation are obscured.When this shell fragment was subjected to downward pressure, owing to base plate 1 maintains static, so 3 on top board can move down.At this moment, skewed elastic plate 2 moves toward the direction of base plate 1 by first linkage section 21, makes second bending segment 34 promote the top arm 32 of pulling simultaneously, thus make the top pull arm 32 upwards the section of turning up 33 of bending on the one side of base plate 1 to front slide.So, this shell fragment can be realized the level and smooth of shift motion during force compresses outside being subjected to; After treating that institute's externally applied forces is removed, first linkage section 21 promptly obtains to discharge, and makes top board 3 produce preferable restoring force by elastic plate 2.
In sum, the elastic piece structure of anti electromagnetic wave of the present utility model can be realized described effect by above-mentioned structure.
Yet, the above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are done, directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present utility model.
