【考案の詳細な説明】
本案は主に配電盤に使用する可溶筒の保持器に関するも
のである。[Detailed description of the invention] The present invention relates to a retainer for a fusible cylinder mainly used in a switchboard.
可溶筒の両端キャップ部を挾む込むクリップが固定され
た絶縁性の台と可溶筒を保持する蓋との組合せからなり
、蓋を台に重ね合せることによって可溶筒がクリップに
扶持されて蓋と台とが固定され、これらを互いに離すこ
とによって可溶筒がクリップから外される構造の保持器
においては、可溶筒を蓋(カバー)に取外し交換可能に
且つ台(ベース)への着脱の際に蓋から外れないように
保持しなければならない。It consists of a combination of an insulating base to which clips that hold the caps at both ends of the fusible cylinder are fixed, and a lid that holds the fusible cylinder. By overlapping the lid with the base, the fusible cylinder is supported by the clips. In a retainer that has a structure in which the lid and the base are fixed, and the fusible tube is removed from the clip by separating them from each other, the fusible tube can be removed and replaced from the lid (cover), and the fusible tube can be attached to the base. It must be held so that it does not fall off the lid when it is attached or removed.

(実開昭49−110249号公報、実開昭53973
60号公報)のが通常の保持手段であった。Conventionally, the holding part was formed into a lid, the central insulating cylinder part of the fusible cylinder was fitted into the hole, and the central insulating cylinder part of the fusible cylinder was held in place. Kaisho 49-13
(see Japanese Utility Model Publication No. 1543), or fixed using a protrusion (Utility Model Application Publication No. 49-110249, Japanese Utility Model Application No. 53973)
60) was the usual holding means.
しかしながら、これらは可溶筒を蓋に固定して保持させ
ているので台と蓋更に可溶筒との間に寸法差があったと
きクリップに可溶筒両端のキャップを完全に扶持させて
充分な電気的接続を行うことができない場合があり、ま
た可溶筒の蓋への取外し交換も簡単でない構造が多く、
更に台と蓋とを組合せた構造では通電時に発生する熱を
電気的に安全な個所から放熱させにくい等の問題点があ
る。However, with these, the fusible tube is fixed to the lid, so if there is a dimensional difference between the base and the lid, or even the fusible tube, the clip can completely support the caps at both ends of the fusible tube. In some cases, it may not be possible to make a proper electrical connection, and in many cases, it is not easy to remove and replace the fusible tube lid.
Furthermore, the structure in which the stand and the lid are combined has the problem that it is difficult to radiate the heat generated when electricity is applied from an electrically safe location.
本案はこれらの問題点を解決したものであって、以下そ
の実施例を図面に就いて説明する。The present invention solves these problems, and examples thereof will be described below with reference to the drawings.
図において1は台、2は蓋を示し、いずれも硬質合威樹
脂、ベークライト、陶磁器等の絶縁材料で作られている
。In the figure, 1 is a stand and 2 is a lid, both of which are made of insulating materials such as hard synthetic resin, Bakelite, and ceramics.

差込まれている。The stand 1 has shielding walls 3, 3 at the front and rear, and an opening 4, 4 is formed in the center of these walls, and clips 6, 6 and a terminal board 7 are placed on the left and right with a mounting hole 5 in the center in between. , 7 are stacked and fixed by screws 8, 8, and a screw 9 for tightening the conductive wire.
, 9 are screwed onto the terminal plates 7, 7 and inserted into the holes 10, 10 of the base 1.
蓋2は遮壁3,3に載って台1に重ね合せられる大きさ

突出形威されている。The lid 2 is made in a size that can be placed on the shielding walls 3, 3 and superimposed on the stand 1, and has skirt walls 11, 11 formed at the front and rear of the center thereof, which fit into the openings 5, 5. A holding part 12 with a U-shaped side surface into which the central insulating cylinder part Fa of the fusible cylinder F is loosely fitted is formed between these parts, the upper surface of which is opened by a window hole 13, and one side of the window hole 13 is formed. A handle 14 is protruded from the top surface of the handle.
蓋2の内面即ち保持部12が形威されている面には可溶
筒Fの両端の導電性のキャップFb,Fb,の左右端面
に接する突起15.16が可溶筒Fの長さより少し大き

側面円弧形の受座17.18および傾斜面19.20が
順に形威され、更に保持部12の一側方に中央絶縁筒部
Faへ接触係合する弾性爪21が突出形或されている。On the inner surface of the lid 2, that is, the surface where the holding part 12 is formed, there are protrusions 15 and 16 that are in contact with the left and right end surfaces of the conductive caps Fb, Fb, at both ends of the fusible tube F, which are slightly longer than the length of the fusible tube F. Following these protrusions 15.16, arcuate side seats 17.18 and inclined surfaces 19.20, which contact the caps Fb and Fb, are formed in order toward the central window hole 13. Further, on one side of the holding portion 12, an elastic pawl 21 is formed to protrude and engage in contact with the central insulating cylinder portion Fa.
第3図、第5図において左側の第一の突起15は右側の
第二の突起16より低く形威されて居り、可溶筒Fを左
側から保持部12の孔22へ斜めに緩く挿入しその先端

うにせり上げながらすべらせ第二の突起16に衝るまで
前進させることにより、左右の受座17,18のいずれ
かまたは両方に接し且つ反対側で弾性爪21に接する。In FIGS. 3 and 5, the first protrusion 15 on the left side is lower than the second protrusion 16 on the right side, and the fusible cylinder F is loosely inserted from the left side into the hole 22 of the holding part 12. By raising the peripheral edge of the tip along the second inclined surface 20 so as to be parallel to the lid 2 and sliding it forward until it hits the second protrusion 16, either the left or right catch seats 17, 18 can be moved. or both, and the elastic claw 21 on the opposite side.
このようにして可溶筒Fを保持した蓋2を台1に重ね、
裾壁11を開口部4に嵌合すると共にキャップF b
, F bをクリップ6,6に挾持させて固定する。The lid 2 holding the fusible tube F in this way is stacked on the stand 1,
While fitting the hem wall 11 into the opening 4, the cap F b
, Fb are held and fixed by the clips 6, 6.
裾壁11,11は中央部に割溝状の開口23.23を有
し且つ左右面は開口部4,4の左右面より大きい傾斜に
作られているので開口23.23を縮小しながら開口部
4,4へ押込み嵌合され第2.3.4図の状態で蓋2が
台1に固定されるのである。The skirt walls 11, 11 have a groove-shaped opening 23.23 in the center, and the left and right sides are made with a larger slope than the left and right sides of the openings 4, 4, so the opening 23.23 can be reduced while the opening 23.23 is being reduced. The lid 2 is press-fitted into the parts 4, 4, and the lid 2 is fixed to the base 1 in the state shown in Fig. 2.3.4.
蓋2を台1から外すときは摘手14を引張って可溶筒F
をクリップ6,6から抜出すもので、保持されている可
溶筒Fは第3図左方向へ引張り或いは押すことによって
取外される。When removing the lid 2 from the stand 1, pull the handle 14 and remove the fusible cylinder F.
is pulled out from the clips 6, 6, and the held fusible tube F is removed by pulling or pushing it toward the left in FIG.

な電気的接続を行うことができるものである。As described above, the present invention has a stand 1 which has clips 6, 6 and is provided with shielding walls 3, 3 at the front and rear, which have openings 4, 4 formed in the center.
and a lid 2 that movably holds the fusible cylinder without fixing it by at least two parts: the left and right protrusions 15, 16 on the inner surface, the seats 17, 18, and the holding part 12 and elastic claws 21 between them. Therefore, in a combination structure in which the base 1 and the lid 2 are completely separable as in the illustrated embodiment, both ends of the fusible cylinder are integral with the lid 2 or separate from the lid 2, regardless of the orientation of the lid 2. The elastic claws 21, which are integral with or separate from the two catch seats 17.18 and the holding part 12 located on the opposite side thereof, are supported by the holding part 12 and are movable. Not only does it prevent the melting cylinder from falling off,
Since the fusible cylinder is movably held by the elastic claw 21 and other parts, even if there is a dimensional difference between the base and the lid, the fusible cylinder, and the clip, the dimensional difference is absorbed by the fusible cylinder moving to a certain extent. The caps on both ends can be completely held in the clips to make a complete electrical connection.

好に行われるのである。In addition, the clip and cap are surrounded by shielding walls 3, 3 on the front and rear of the stand 1, and the lid 2, so the conductive parts are protected from being exposed and are highly safe. A window hole 13 is formed on the top surface of the holding part 12 at the location where the
Since there are provided openings 23 and 23 at the front and rear, heat dissipation during energization can be effectively carried out from an electrically safe location.
更にまた台1と蓋2とは開口部4,4に裾壁11,11

正確な着脱が行える等の効果を有するものである。Furthermore, the base 1 and the lid 2 have skirt walls 11, 11 in the openings 4, 4.
By fitting them together, they can be assembled by overlapping each other accurately and can be attached and detached accurately.
