Description
Technical field
The utility model relates to terminal protecting cover class, the particularly a kind of and supporting insulation protective jacket of fast connecting terminal.
Background technology
The insulated terminal protective sleeve is and the supporting use of connecting line terminal, plays the insulation protection effect.Mainly be used on the electrical equipment internal circuit connecting line.The characteristics of conventional rear-mounted insulated terminal protective sleeve are that distribution terminal penetrates from the sheath inlet and just can enter in the sheath chamber through a segment distance; terminal screens place has groove one because sheath enters the mouth; size is narrowed down; resistance ratios is bigger when binding post passes through; adding some power could pass through; so this type sheath, threading speed is slower, and production efficiency is affected.Though this place's size suitably can be widened, make the terminal ratio be easier to by, so, protective sleeve can come off easily and make terminal lose insulation protection.
Summary of the invention
The purpose of this utility model is to provide a kind of and not only had been inserted in easily, but also do not allow caducous and the supporting insulation protective jacket of fast connecting terminal.
The technical solution that the utility model proposed is such: a kind of and supporting insulation protective jacket of fast connecting terminal; comprise insulating case body 16 and internal cavity thereof; these insulating case body 16 two ends are respectively equipped with terminal inlet 11 and inserted sheet inlet 15; described insulating case body 16 stage casings are provided with terminal screens portion 13; before the face 12 of this terminal screens portion 13; rear side is respectively equipped with terminal retaining groove 13-1; corresponding before the facial inwall of terminal screens portion 13; rear side is formed with terminal screens boss 13-2 respectively; between this terminal retaining groove 13-1 and the inserted sheet inlet 15 is terminal cavities 14; central authorities are provided with the tongue 14-1 that leads longitudinally at the facial inwall of terminal cavities 14, are provided with cydariform sidepiece 17 in the both sides, stage casing of insulating case body 16.
The bottom 18 of insulating case body 16 is positioned at terminal screens portion 13 places and is provided with the 1st inclined-plane 18-1, angle α=9-10 ° angle of the 1st inclined-plane 18-1 and horizontal plane.Cover body face between cydariform sidepiece 17 and terminal inlet 11 is provided with the 2nd inclined-plane 12-1, angle β=3-4 ° angle of the 2nd inclined-plane 12-1 and horizontal plane.Cover body both sides between cydariform sidepiece 17 and the terminal inlet 11 are wide, and the cover body both sides between cydariform sidepiece 17 and the inserted sheet inlet 15 all are the shape of a saddle.
Compared with prior art, the utlity model has following beneficial effect:
(1) because both sides, this fast connecting terminal insulation protective jacket middle part is provided with the cydariform sidepiece; stage casing, protective sleeve bottom is provided with an inclined-plane; face between the cydariform sidepiece of cover body and the terminal inlet is the inclined-plane; thereby; terminal is inserted into from terminal inlet easily and passes the terminal retaining groove in the sheath and be stuck; and the facial inwall of the terminal cavities of this terminal protective sleeve central authorities are provided with the tongue that leads longitudinally; supporting with it 250 model (comprises 205 types; 187 types; 110 types) fast connecting terminal inserts terminal screens portion and terminal cavities in the sheath from terminal inlet easily; because the guiding tongue has the guide-localization effect to the locked groove of fast connecting terminal; two terminal screens boss have location clamping effect to the locking plate of fast connecting terminal; thereby can be accurately and quickly plug together and be connected with the fast connecting terminal of coupling; so just can accelerate distribution speed, improve final assembly efficient.
(2) because these forward and backward both sides, facial middle part that connect the insulated terminal protective sleeve soon are respectively equipped with the terminal retaining groove; select the bigger PVC material of hardness to remove to make this protective sleeve in addition; protective sleeve just is not easy to come off from the terminal of quilt cover like this, and protective sleeve is guaranteed reliably to the insulation protection of terminal.
The utility model mainly is applicable to and 250 model and 205 types, 187 types, the supporting use of 110 type fast connecting terminals.
