Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation, but not as the qualification to the utility model.
To shown in Figure 3, the pressure instrument of the embodiment of the utility model is used for fast, safety, realization once reliably, the secondary cable plugs into like Fig. 1.Said pressure instrument comprises: first housing 1, second housing 2, bolt 7, torque nut 5 and hold-down nut 6; Bolt 7 passes first housing 1 and second housing 2; Torque nut 5 and hold-down nut 6 are located at the same end of bolt 7; Hold-down nut 6 is positioned contiguous first housing 1, and torque nut 5 be positioned can be along the length direction relative motion of bolt 7 away from first housing, 1, the first housing 1 and second housing 2; First housing 1 and second housing, 2 relative sides are formed with groove respectively, after the two assembling, form a main line groove and a wire casing; Be equipped with rubber cushion 4 in the groove; Be respectively arranged with one or more puncture blades 3 in the groove, puncture blade 3 is hidden in the rubber cushion 4, and lays respectively between the puncture blade 3 in main line groove and the wire casing and be electrically connected; An end that props up wire casing is provided with the end of a thread protective sleeve 8.The exposed end that the end of a thread protective sleeve 8 is used to the secondary cable provides insulation protection, to prevent Danger Electric shock risk.In the present embodiment, torque nut 5 adopts common torque nut, and specification is H14/10 (mm/Nm).The diameter of main line groove is 16mm-95mm, and the diameter of a wire casing is 1.5mm-10mm, to adapt to the on-the-spot application need of all kinds of meterings.
In addition, the pressure instrument of present embodiment also comprises the waterproof apron (not shown), and it is arranged on first housing 1 and second housing 2 is inner and match with the internal structure of first housing 1 and second housing 2.Because the global shape of waterproof apron is consistent with the enclosure interior structure of pressure instrument, therefore, waterproof apron can not be subjected to displacement in the pressure instrument.Further, waterproof apron is provided with the slit that supplies puncture blade 3 to embed, and puncture blade 3 embeds wherein 2mm.
Carrying out cable when plugging into, a cable is passed from the main line groove, the secondary cable that needs T to connect is inserted in the end of a thread protective sleeve 8; Nut 6 then is tightened; And then clamp load torque nut 5, in the process of clamp load torque nut 5, be hidden in that puncture blade 3 in the rubber cushion 4 thrusts once gradually, the insulation sheath of secondary cable; And finally with once, the metal section and part of the heart yearn of secondary cable fully contacts; Last torque nut 5 comes off after fastening abundant automatically, and the relative position of whole device is stuck, thereby realizes best water resistance and electric effect.
As a preferred version of present embodiment, lay respectively at the main line groove and be configured to the double blade integrative-structure with the top of a wire casing or the puncture blade 3 of bottom, adopt whole crossbeam to connect between the main line tooth 11 of double blade and the branch line tooth 10.The main line tooth 11 of puncture blade 3 is provided with three cutters tooth, and both sides cutter tooth height is 4mm, and middle cutter tooth height is 3mm; Branch line tooth 10 is provided with three cutters tooth, and both sides cutter tooth height is 3mm, and middle cutter tooth height is 2mm; Interdental space is 1.5mm, to satisfy the needs of cutting cable arc surface.In addition, puncture blade 3 is set to laterally zygomorphic two groups, and promptly two puncture blades 3 are arranged in the groove of first housing 1, and two puncture blades 3 are arranged in the groove of second housing.
