Specific embodiment
Hereinafter, the embodiments of the present invention will be described with reference to the drawings.
(embodiment 1)
FIG. 1 to FIG. 4 is the figure for indicating an example of first embodiment of the invention.
The base-plate terminal metalwork 1a of first embodiment is bent by plate body.
In the example in the figures, sheet metal 10 is bent into "U" shape by punch process etc., become with top plate 2 with
The construction of the wall surface in three faces as side wall 3,3.
In the illustrated embodiment, have in the lower end side of side wall 3,3 for the circuit base to printed circuit board etc.
Fixation claw, the i.e. fixed jaw 4,4 that plate is fixed.Also, top plate 2 is connected in the upper end side of side wall 3,3.
In the illustrated embodiment, the through-hole 6 penetrated through from the outer side of top plate 2 to private side is formed on top plate 2.
Also, it is configured with cylindrical body 5 in the private side of top plate 2, which has the hollow portion being connected to through-hole 6,
Internal thread part 7 is formed on internal perisporium.Cylindrical body 5 is that have the cylindrical body with the end of bottom surface 5a.
Structure example as described above can such as be shaped by following methods: make the central portion of top plate 2 using drawing process
Formed as shown in Figure 3, the recess portion of the closed cylindrical shape of bottom surface 5a, using rolled tap processing the recess portion interior table
Face forms internal screw thread 7.The cylindrical body 5 at bottom is integrally formed with top plate 2.
Alternatively, although not shown, also can through top plate 2 central portion through-hole 6 is set, will be provided with being connected to through-hole 6
The hollow portion and box nut that internal thread part 7 is formed on internal perisporium is mounted on the private side of top plate 2 and forms cylindrical body 5.It will
Cylindrical body 5 with the end is set as and the independent construction of top plate 2.
Fig. 4 is to indicate using base-plate terminal metalwork 1a, and the connection terminal of electronic instrument etc. is connect with circuit substrate
The concept map of state.
By screwing togather external screw thread 9 and the internal screw thread 7 of cylindrical body 5, the connection terminal 8 of electronic instrument etc. is mounted on edge of substrate
On sub- metalwork 1a.
When external screw thread 9 is fastened towards the direction of arrow 11 to internal screw thread 7, or by external screw thread 9 towards arrow 12
When direction is dismantled from internal screw thread 7, sheet metal etc. is generated from internal screw thread 7 and external screw thread 9 sometimes and cuts generated foreign matter.Even if
In the case where producing foreign matter, bottom surface 5a is closed by making cylindrical body 5 as described above, which is stayed in into cylindrical body 5.Cause
This, sheet metal etc. cuts the downside that generated foreign matter does not fall out base-plate terminal metalwork 1a in Fig. 4.
Therefore, it can prevent the foreign matter from dropping to described circuit substrate (not shown) etc..
Fig. 5 (a), Fig. 5 (b) are the figures for indicating other example of first embodiment.
In Fig. 5 (a), Fig. 5 (b) embodiment illustrated, top plate 2 is not horizontal as the embodiment of FIG. 1 to FIG. 4
But obliquely configure obliquely.
Therefore, the cylindrical body 5 of the private side of top plate 2 is formed in also not as the embodiment of FIG. 1 to FIG. 4 towards lead
Construction from histogram to extension, but with the inclination of top plate 2 accordingly obliquely downward to obliquely being configured.
The function of the base-plate terminal metalwork 1b of Fig. 5 (a), Fig. 5 (b) diagram and the substrate being illustrated using FIG. 1 to FIG. 4
Terminal metal piece 1a is identical.Therefore, identical appended drawing reference is marked to base-plate terminal metalwork 1a general structure, omits it
Explanation.
(embodiment 2)
Fig. 6 is the figure for indicating an example of second embodiment of the present invention.To the edge of substrate with first embodiment
Sub- metalwork 1a general structure marks identical appended drawing reference, and the description thereof will be omitted.
In the base-plate terminal metalwork 1c of present embodiment, has the circuit base to printed circuit board etc. in lower end side
The fixed fixation claw of plate, i.e. a side in the side wall 3,3 of fixed jaw 4,4 side wall 3 on, formation from the side wall 3 outside
The through-hole 6 that portion side is penetrated through to private side.
Also, in the private side of the side wall 3 configured with having the hollow portion being connected to through-hole 6 and be formed in internal perisporium
The cylindrical body 5 of internal thread part 7.Cylindrical body 5 is that have the cylindrical body with the end of bottom surface 5b.
That is, being formed from the outer side of top plate 2 to private side and being penetrated through in the base-plate terminal metalwork 1a of first embodiment
Through-hole 6, configure cylindrical body 5 with the end in the private side of the top plate 2.In the base-plate terminal metalwork 1c of the second embodiment
In, the through-hole 6 that penetrate through from the outer side of side wall 3 to private side in formation, in the private side configuration cylindrical body with the end of the side wall 3
On 5 this aspect, it is different from the first embodiment.
The case where manufacturing process of above-mentioned construction, the effect played by above-mentioned construction, effect are with first embodiment is identical.
The connection terminal 8 of electronic instrument etc. makes external screw thread 9 and cylindrical body identically as the case where using Fig. 4 to be illustrated
5 internal screw thread 7 screws togather, and is thus mounted on base-plate terminal metalwork 1c.
When external screw thread 9 is fastened towards the direction of arrow 13 to internal screw thread 7, or by external screw thread 9 towards arrow 14
When direction is dismantled from internal screw thread 7, even if generating from internal screw thread 7 and external screw thread 9 because different caused by the cutting such as sheet metal
Object, the foreign matter can also stay in the inside of cylindrical body 5.This is because cylindrical body 5 makes the side plate with described another party as described above
The bottom surface 5b of 3 opposite sides is closed.
Therefore, the foreign matter can be dropped to described circuit substrate (not shown) etc. to prevent trouble before it happens.
Fig. 7 (a), Fig. 7 (b) are the figures for indicating other example of second embodiment.
Fig. 7 (a), Fig. 7 (b) embodiment illustrated base-plate terminal metalwork 1d do not have top plate 2.On the other hand, have
The standby two side walls 3,3 for forming the side wall 3 of cylindrical body 5 in private side and extending along the direction that cylindrical body 5 extends.
In addition, not having the side wall 3 for the bottom surface side for being present in cylindrical body 5 in the embodiment of fig. 6.
The function of the base-plate terminal metalwork 1d of Fig. 7 (a), Fig. 7 (b) diagram also with the sheet that uses FIG. 1 to FIG. 6 to be illustrated
1a, 1b, 1c of invention are identical, mark identical appended drawing reference to general structure, the description thereof will be omitted.
More than, with reference to the accompanying drawings of the preferred embodiment of the present invention, but the present invention is not limited to the embodiment, energy
It is enough to be changed to various forms out of the record of claims is grasped technical scope.
