Embodiment
Below, with reference to accompanying drawing, embodiments of the present invention are described.
(execution mode 1)
Fig. 1 ~ Fig. 4 is the figure of the example representing the first execution mode of the present invention.
The base-plate terminal metalwork 1a of the first execution mode forms by plate body is bending.
In the example in the figures, sheet metal 10 is bent into " コ " shape by punch process etc., becomes the structure with top board 2 and sidewall 3,3 such walls of three.
In the illustrated embodiment, fixing claw, the i.e. fixed claw 4,4 for being fixed to the circuit substrate of tellite etc. is possessed in the lower end side of sidewall 3,3.Further, top board 2 is connected with in the upper end side of sidewall 3,3.
In the illustrated embodiment, top board 2 is formed from the outer side of top board 2 to the through through hole 6 of private side.
Further, be configured with cylindrical body 5 at the private side of top board 2, this cylindrical body 5 possesses the hollow bulb be communicated with through hole 6, and internal perisporium is formed internal thread part 7.Cylindrical body 5 is the cylindrical body with the end with bottom surface 5a.
Structure as described above such as can be shaped by following method: utilize drawing to process to make the central portion of top board 2 formed as shown in Figure 3, the recess of drum that bottom surface 5a closes, utilize rolled tap to process and form internal thread 7 at the inner surface of described recess.The cylindrical body 5 at the end is integrally formed with top board 2.
Or, although not shown, through hole 6 is set with also can running through the central portion of top board 2, will the hollow bulb be communicated with through hole 6 be possessed and the box nut being formed with internal thread part 7 on internal perisporium is arranged on the private side of top board 2 and forms cylindrical body 5.Cylindrical body 5 with the end is set to and independently constructs with top board 2.
Fig. 4 represents to use base-plate terminal metalwork 1a, by the concept map of the state that the splicing ear of electronic instrument etc. is connected with circuit substrate.
By making external screw thread 9 screw togather with the internal thread 7 of cylindrical body 5, the splicing ear 8 of electronic instrument etc. is arranged on base-plate terminal metalwork 1a.
When external screw thread 9 is carried out fastening towards the direction of arrow 11 to internal thread 7, or when external screw thread 9 is dismantled from internal thread 7 towards the direction of arrow 12, sometimes produce sheet metal etc. from internal thread 7 and external screw thread 9 and cut the foreign matter produced.Even if when creating foreign matter, by making cylindrical body 5 make bottom surface 5a close as described above, this foreign matter is stayed cylindrical body 5.Therefore, sheet metal etc. cut the downside that the foreign matter produced can not drop to base-plate terminal metalwork 1a in the diagram.
Therefore, it is possible to prevent described foreign matter from dropping to described circuit substrate (not shown) etc.
Fig. 5 (a), Fig. 5 (b) are the figure of other example representing the first execution mode.
In the illustrated execution mode of Fig. 5 (a), Fig. 5 (b), top board 2 not as the execution mode of Fig. 1 ~ Fig. 4 level but configure obliquely obliquely.
Therefore, the cylindrical body 5 being formed in the private side of top board 2 also not as the execution mode of Fig. 1 ~ Fig. 4 towards the structure of vertical direction extension, but with the inclination of top board 2 accordingly obliquely downward to configuring obliquely.
The function of Fig. 5 (a), Fig. 5 (b) illustrated base-plate terminal metalwork 1b is identical with the base-plate terminal metalwork 1a using Fig. 1 ~ Fig. 4 to be described.Therefore, mark identical Reference numeral to the structure general with base-plate terminal metalwork 1a, the description thereof will be omitted.
(execution mode 2)
Fig. 6 is the figure of the example representing the second execution mode of the present invention.The structure general to the base-plate terminal metalwork 1a with the first execution mode marks identical Reference numeral, and the description thereof will be omitted.
In the base-plate terminal metalwork 1c of present embodiment, possess in lower end side on the sidewall 3 of the side in the sidewall 3,3 of fixing fixing claw, the i.e. fixed claw 4,4 of the circuit substrate to tellite etc., formed from the outer side of this sidewall 3 to the through through hole 6 of private side.
Further, be configured with at the private side of this sidewall 3 hollow bulb that possesses and be communicated with through hole 6 and be formed with the cylindrical body 5 of internal thread part 7 at internal perisporium.Cylindrical body 5 is the cylindrical body with the end with bottom surface 5b.
That is, in the base-plate terminal metalwork 1a of the first execution mode, formed from the outer side of top board 2 to the through through hole 6 of private side, configure cylindrical body 5 with the end at the private side of this top board 2.In the base-plate terminal metalwork 1c of this second execution mode, forming the through hole 6 through to private side from the outer side of sidewall 3, configuring this aspect of cylindrical body 5 with the end at the private side of this sidewall 3, different from the first execution mode.
The manufacturing process of above-mentioned structure, the effect played by above-mentioned structure, effect are identical with the situation of the first execution mode.
The splicing ear 8 of electronic instrument etc., identically with the situation using Fig. 4 to be described, make external screw thread 9 screw togather with the internal thread 7 of cylindrical body 5, is arranged on thus on base-plate terminal metalwork 1c.
When external screw thread 9 is carried out fastening towards the direction of arrow 13 to internal thread 7, or when external screw thread 9 is dismantled towards the direction of arrow 14 from internal thread 7, even if produce because sheet metal etc. cuts the foreign matter produced from internal thread 7 and external screw thread 9, this foreign matter also can stay the inside of cylindrical body 5.This is because cylindrical body 5 makes the bottom surface 5b of the side relative with the side plate 3 of described the opposing party close as described above.
Prevent trouble before it happens therefore, it is possible to described foreign matter to be dropped to described circuit substrate (not shown) etc.
Fig. 7 (a), Fig. 7 (b) are the figure of other example representing the second execution mode.
The base-plate terminal metalwork 1d of the illustrated execution mode of Fig. 7 (a), Fig. 7 (b) does not possess top board 2.On the other hand, the sidewall 3 forming cylindrical body 5 at private side and two sidewalls 3,3 extended along the direction that cylindrical body 5 extends are possessed.
In addition, the sidewall 3 of the bottom surface side being present in cylindrical body 5 is not possessed in the embodiment of fig. 6.
The function of Fig. 7 (a), Fig. 7 (b) illustrated base-plate terminal metalwork 1d is also identical with 1a, 1b, 1c of the present invention of using Fig. 1 ~ Fig. 6 to be described, and mark identical Reference numeral to general structure, the description thereof will be omitted.
Above, with reference to the accompanying drawings of the preferred embodiment of the present invention, but the present invention is not limited to this execution mode, can carry out changing to various form in the technical scope grasped in the record of accessory rights claim.
