Specific embodiment
Embodiment 1
Figure 1A is the front view illustrating to possess the electronic equipment 1 of the conducting construction of embodiment 1 of the present utility model.Figure 1B It is the profile illustrating the section along line A-A sectility by the electronic equipment 1 of Figure 1A.
Electronic equipment 1 is, for example, the vehicle-mounted electronic equipments such as vehicle navigation apparatus, possesses liquid crystal panel 2 and housing 3.As Shown in Figure 1A, liquid crystal panel 2 is to expose to outside composed component from the one side of housing 3, and it makes in the outside direct capacitance producing Easily it is transferred to the circuit substrate of inside.
For example, as shown in Figure 1B, liquid crystal panel 2 exist liquid crystal portion 2A be held in frame 4B and circuit substrate (not shown) peace It is loaded on the situation of frame 4B.In addition, the display surface side in liquid crystal portion 2A is assembled with protection board 2B, protection board 2B is assembled in housing 3 Front-surface side.Constituted due to such, therefore there is the electrostatic producing in protection board 2B or housing 3 and pass through protection board 2B and housing Gap between 3, and it is transferred to the situation of foregoing circuit substrate from frame 4B of metallic plate.
On the other hand, in the past using by frame 4A located at earthing potential, and by between frame 4A and frame 4B via conduction Property part electrical connection, thus prevent electrostatic to be transferred to the construction of circuit substrate.
However, as described above, as the antirust countermeasure of the frame of metallic plate, it is to be existed by plating etc. in most cases Top layer forms the protecting film with electrical insulating property.
In this case, if only electroconductive component is clamped each other by frame, the conducting between frame and electroconductive component Insufficient it is possible to frame cannot be made fully to electrically connect each other.
On the other hand, conducting construction of the present utility model possesses prominent face by part punch process etc., this prominent face Have:Outer peripheral face from the frame planar portions projecting and the metal plate component exposing substrate.Electroconductive component be configured to from outer The metal plate component contact of the substrate that side face exposes.
So, exposed from the outer peripheral face of prominent face by making the metal plate component of substrate, thus record with such as patent documentation 1 Combined structure make the structure phase that the crackle of the metal plate component of the substrate protecting film of apex portion from jut exposes like that Ratio can be in each layer more amount exposed.In addition, by the overhang changing planar portions, substrate thus also can be adjusted Metal plate component the amount of exposing.
Fig. 2A is the sectional view of the conducting construction illustrating embodiment 1, illustrates only frame 4A to be provided with prominent face 4A-4 Construction.In this configuration, the frame of the protecting film without electrical insulating property is for example used as frame 4B.In addition, Fig. 2 B is The sectional view of another example of the conducting construction of embodiment 1 is shown, is shown in frame 4A setting prominent face 4A-4, in frame 4C It is also provided with the construction of prominent face 4C-4.
In fig. 2, frame 4A is the composed component embodying the first component in this utility model, metal plate component 4A-1 is the part being covered by protecting film 4A-2, the 4A-3 with electrical insulating property.That is, in the table of the side of metal plate component 4A-1 Layer is formed with the protecting film 4A-2 of electrical insulating property, is formed with protecting film 4A-3 on the top layer of opposite side.
Prominent face 4A-4 is to be formed with planar portions 4A-5, and the metal of substrate from a part of prominent state of frame 4A Plate member 4A-1 is exposed from the outer peripheral face 4A-6 of planar portions 4A-5.
The part of the substrate contact that electroconductive component 5 is arranged to and the outer peripheral face 4A-6 from planar portions 4A-5 exposes, example As there is electric conductivity and being made up of spongiform soft part.
Specifically, the example covering sponge member with the metal netted thin plate such as rustless steel can be included.This When being clamped by frame 4A and frame 4B, as shown in Figure 2 A, prominent face 4A-4 becomes the shape of sinking to the electroconductive component 5 that sample is constituted State, thus with the substrate contact exposing from outer peripheral face 4A-6.
For example, the size of the short transverse of the electroconductive component 5 before by frame 4A and the clamping of frame 4B is the situation of 5mm Under, frame 4A and frame 4B clamping electroconductive component 5, by the size compression of the short transverse of electroconductive component 5 to becoming 2.5mm Left and right.The face 4A-4 that thus dashes forward sinks to electroconductive component 5, makes substrate and electroconductive component 5 reliability exposed from outer peripheral face 4A-6 Ground contact.
In fig. 2b, frame 4C is the composed component embodying second component of the present utility model, metal plate component 4C- 1 is the part being covered by protecting film 4C-2, the 4C-3 with electrical insulating property.That is, protecting film 4C-2 is formed at metal plate component 4C- The top layer of 1 side, protecting film 4C-3 is formed at the top layer of opposite side.
In addition, frame 4C can also frame 4B as shown in Figure 1B like that, be to maintain the machine of the metallic plate of liquid crystal portion 2A Frame.
Prominent face 4C-4 is same with frame 4A, is formed with planar portions 4C-5 from a part for frame 4C with prominent state, And the metal plate component 4C-1 of substrate exposes from outer peripheral face 4C-6.
As shown in Figure 2 B, because electroconductive component 5 is configured to and the substrate contact exposing from outer peripheral face 4C-6, therefore frame 4C is turned on frame 4A via electroconductive component 5.
Fig. 3 A is to illustrate to constitute the metal plate component of conducting construction of embodiment 1 and the axonometric chart of electroconductive component, Frame 4A and the electroconductive component 5 being configured at frame 4A are shown.And, Fig. 3 B is to illustrate frame 4A of Fig. 3 A and conduction The section direction view of the property section along line B-B sectility for the part 5.
Fig. 4 A is the axonometric chart illustrating to constitute the metal plate component of conducting construction of embodiment 1, is shown provided with prominent face Frame 4A of portion 4A-4.Fig. 4 B is the section direction view illustrating the section along line C-C sectility by frame 4A of Fig. 4 A.
In the past, there is construction frame being electrically connected to each other via electroconductive component, electroconductive component is by using viscous Connect agent or two-sided tape and be installed on frame.
In this configuration, if bonding agent or two-sided tape are electrical insulating properties, they can become obstruction frame and conduction Property part electrical connection key factor.
On the other hand, as shown in fig. 4 a and fig. 4b, the prominent face 4A-4 in this utility model has only makes planar portions 4A-5 The construction projecting from frame 4A, and planar portions 4A-5 are formed on the protecting film 4A-2 covering on the top layer of frame 4A.
But, as shown in Fig. 3 A and Fig. 3 B, by making electroconductive component 5 and the substrate contact exposing from outer peripheral face 4A-6, To guarantee the conducting of frame 4A and electroconductive component 5.
Thus, electroconductive component 5 is by being configured at the bonding agent of the electrical insulating property on the protecting film 4A-2 of planar portions 4A-5 Or two-sided tape and be installed on frame 4A.
So, the conducting of without prejudice to frame 4A and electroconductive component 5, and electroconductive component 5 can be installed on frame 4A.
In addition, in Figure 4 A although being shown provided with the situation of two prominent face 4A-4 but it is also possible to be one or three More than.
Fig. 5 is the brief schematic diagram of the manufacture method of the conducting construction illustrating embodiment 1, illustrates to form prominent face Frame 4A of 4A-4 and the section being configured with the mould 6 of this frame 4A along the pressing direction sectility of drift 7.
