各端子板6是藉由導電性金屬板構成，如圖2～4所示，為一體具備有電連接輸出端子3的端子連接部17、電連接逆流防止用二極體(以後僅稱為二極體)18的二極體連接部19；以及電連接輸出纜線4的纜線連接部20的構成，藉由立設在盒本體1的底板1c的卡止爪1e被固定(參閱圖1)。Each terminal plate 6 is formed of a conductive metal plate. As shown in FIGS. 2 to 4, the terminal plate 6 is integrally provided with a terminal connection portion 17 electrically connected to the output terminal 3, and a diode for electrical connection backflow prevention (hereinafter referred to as only two). The diode connection portion 19 of the pole body 18; and the cable connection portion 20 electrically connecting the output cable 4 are fixed by the locking claw 1e of the bottom plate 1c of the cartridge body 1 (see Fig. 1). ).
前述端子連接部17是如圖2所示，設置有讓輸出端子3的前端部穿過的略矩形形狀的插通孔17A；與從插通孔17A的周部的一邊切割立起的搖動卡止片部17B的構成。作為往端子連接部17的輸出端子3的安裝的一個例子，可舉例例如將輸出端子3的前端部穿過插通部17A的狀態下，朝插通孔17A推回搖動卡止片部17B，將輸出端子3夾壓在插通孔17A的內周緣部17a與搖動卡止片部17B的搖動前端側緣部17b之間的狀態下進行固定等的方法。再者，也可對與端子連接部17的上面重疊的輸出端子3部分進行焊接。As shown in FIG. 2, the terminal connecting portion 17 is provided with a substantially rectangular insertion hole 17A through which the front end portion of the output terminal 3 passes, and a rocking card which is cut up from one side of the peripheral portion of the insertion hole 17A.

A method of fixing the output terminal 3 between the inner peripheral edge portion 17a of the insertion hole 17A and the rocking distal end side edge portion 17b of the rocking engagement piece portion 17B is performed. Further, the portion of the output terminal 3 that overlaps the upper surface of the terminal connecting portion 17 may be welded.
又，端子連接部17的兩側緣部是構成朝上方側切割立起的肋17C，謀求端子連接部17的補強。該肋17C成為前述盒本體1的卡止爪1e卡止的對象部分。Further, the both side edge portions of the terminal connecting portion 17 constitute a rib 17C that is cut and raised toward the upper side, and the terminal connecting portion 17 is reinforced. This rib 17C serves as a target portion to which the locking claw 1e of the cartridge body 1 is locked.
前述二極體連接部19是如圖2、圖3所示，其兩側緣部作為朝上方側切割立起呈肋狀切割立起的切起部19C，另一方面，寬方向的中央部構成作為使端子板6的面部分鼓出的鼓出部19A。As shown in FIG. 2 and FIG. 3, the two-part connecting portion 19 has a cut-and-raised portion 19C that is cut and raised in a rib shape toward the upper side, and a central portion in the width direction. A bulging portion 19A that bulges the surface portion of the terminal block 6 is formed.
因此，切起部19C與鼓出部19A之間成為凹部19B。Therefore, the recessed portion 19B is formed between the cut-and-raised portion 19C and the bulging portion 19A.
又，前述在切起部19C一體形成一對的突出部21，該等突出部21的間隔，是設定成可將二極體18的導線18a予以內嵌的尺寸。將導線18a內嵌在一對的突出部21間的狀態下，使一對的突出部21彼此如圖4所示，朝接近的方向塑性變形(鉚合)，可在挾持狀態支撐導線18a。Further, the pair of protruding portions 21 are integrally formed in the cut-and-raised portion 19C, and the distance between the protruding portions 21 is set to a size in which the lead wires 18a of the diode 18 can be embedded.

The solder for connection H tends to spread in a plane in a molten state, but as shown in FIG. 3, since the solder H can be positioned by the recess 19B sandwiched between the protruding portion 21 and the bulging portion 19A, it can be prevented. The other departments are separated.
前述纜線連接部20是如圖2所示，藉由形成可縮徑的狀態的彎曲狀的鉚接部20A構成，在該鉚接部20A上載置著輸出纜線4的金屬芯4a的狀態下，以鉚接部20A圍繞金屬芯4a的狀態予以鉚接，而可在導通狀態連接。As shown in FIG. 2, the cable connecting portion 20 is formed by a curved caulking portion 20A in a state in which the diameter can be reduced, and in a state in which the metal core 4a of the output cable 4 is placed on the caulking portion 20A, The caulking portion 20A is riveted around the metal core 4a, and can be connected in an on state.

Further, in the inner hollow portion of the terminal box B, resin injection can be performed for the purpose of waterproofing, insulation, or the like.
根據本實施形態的端子盒，由於設有凹部19B，可抑制焊料H的脫離，且即使是少量的焊料H的使用量也可確實固定二極體18。According to the terminal box of the present embodiment, since the recess 19B is provided, the detachment of the solder H can be suppressed, and the diode 18 can be surely fixed even with a small amount of the amount of the solder H used.
再者，二極體18的導線18a，對於端子板6，藉由鼓出部19A支撐在載置狀態，並藉由挾持部K所為的挾持支撐、以及凹部19B的焊料固定，可在更確實的狀態固定。Further, the lead wire 18a of the diode 18 can be supported by the bulging portion 19A in the mounted state, and the holding support by the holding portion K and the solder fixing of the concave portion 19B can be more sure. The state is fixed.
再者，其具體的構成，並無須設置特別的零件，可藉由對一片的端子板6的簡單的加工來實現，並可謀求製造成本的降低化。Further, the specific configuration does not require the provision of special parts, and can be realized by simple processing of one terminal plate 6, and the manufacturing cost can be reduced.
