Abstract
The invention relates to a terminal (5) used for connecting an insulated electric lead and an electric switch, the switch is provided with electrically-insulated housings (2, 3), at least an electric connection section (4) protrudes from the housings, the lead provided with a cable boot is fixedly connected on the connection section particularly via screw threads, wherein the terminal (5) is fixed on the connection section (4) at the switch side, and holes (7, 8) are provided at the lead side, the insulated lead end part is inserted in the hole and fixed via a clamping device. In order to ensure reliable connection between the lead and the switch, it is suggested in the invention that, a sign (11) is disposed on one surface (10) disposed at the external side of the terminal (5), and the sign represents the length of insulation before the lead terminal part is inserted into the holes (7, 8).
Description
Technical field
The present invention relates to a kind of be used to the connect electric lead of insulation and the terminal of electric switch.
Background technology
Known ground, a multipole electric loading isolating switch is connected with electric lead with load side in the net side.The described switch that is used for each utmost point or each phase lays respectively in the utmost point box; Described utmost point box is installed in the switch case abreast.The switch of described utmost point box is connected a phase (position) of power supply network respectively with one or more customers.In order to be connected with lead, the projection from described utmost point box or switch case of the linkage section on plane is come out.The described lead that is provided with cable shoes is fixed on this linkage section in the planar side of this linkage section.This can realize by bolt under the simplest situation.For the fixing lead that does not have cable shoes, and be provided with terminal, it has patchhole, and the wire termination of described insulation inserts these patchholes and fixes by clamping device.
The disadvantage of so doing is, can only estimate the length that will insulate when connecting switch roughly.This may cause, owing to removed the insulation sheath of oversize length, may touch plain conductor from the outside after clamping, and owing to lack insulation sheath and no longer have contact protection in this zone.Perhaps, because the insulated lengths of lead is too short, and the insulating material that is used for clamping device is between terminal and the lead, well connects and can not reach between described lead and the terminal.
Summary of the invention
Technical problem to be solved by this invention is, guarantees to be connected reliably between lead and the switch.
Above-mentioned technical problem is used to connect the electric lead of insulation and the terminal of electric switch is solved by a kind of, described electric switch has the housing of electric insulation, from this housing, stretch out the linkage section of a conduction at least, be equipped with the lead of cable shoes especially to be fixed on the described linkage section by being threaded, wherein, described terminal is fixed on this linkage section in switch-side, and has the hole in the lead side, the wire termination of described insulation inserts in this hole and by clamping device and fixes, it is characterized in that, be positioned at of described terminal on the surface in the outside and be provided with mark, this mark is represented the length that described wire termination will insulate before being inserted into described hole.。
Solution regulation of the present invention is provided with mark on the surface that is positioned at the outside of described terminal, this mark is represented the length that described wire termination will insulate before being inserted into the hole.(afterwards in order to check) is by simply fixedly guaranteeing the correct length that insulated to wire termination before insulating barrier is removed.
A kind of simple clamping device design of described terminal is as follows, and the wire termination of described insertion is clamped on the inwall in described hole by a bolt transverse to the longitudinal extension in hole in described hole.
Especially advantageously, described mark is the described lip-deep longitudinal fluting that is positioned at the outside.
For under the situation of die casting terminal advantageously, described terminal is made by pressure casting method jointly with described longitudinal fluting.
Description of drawings
The present invention will be described in detail by accompanying drawing below.In the accompanying drawings,
Fig. 1 shows a switch and two terminals that are connected;
Fig. 2 shows the vertical view of terminal shown in Figure 1;
Fig. 3 shows terminal shown in Figure 1 and can see wherein hole.
Embodiment
Fig. 1 represents the join domain of a multipole electric switch 1, and described electric switch has a switch case 2, for each a utmost point box 3 is installed mutually in this housing, and these utmost point boxes are installed in the switch case abreast.In order to connect the electric lead of insulation, the projection from described utmost point box 3 or switch case 2 of the linkage section 4 on plane is come out, and concrete condition is decided on the housing that in the two which constitutes described switch 1.In being equipped with the lead of cable shoes, described cable shoes is fixed on the planar side of described linkage section 4 by screw bolt and nut.In order also the electric lead that does not have cable shoes to be connected with described switch 1, use terminal 5, itself and cable shoes are fixed on the described linkage section 4 by a bolt 6 and a nut in switch-side similarly.Each terminal 5 has two holes 7,8 at opposite side, and before lead was fixed chucking by bolt 9, the wire termination with insulation inserted in the above-mentioned hole earlier.
Have two vertical marks 11 on the side 10 of on the left side, it is designed to the longitudinal fluting of groove shape at this, because terminal 5 is made by pressure casting method.Certainly, vertically mark 11 also can be simple color mark, this color mark for example by laser cladding on described side 10.
Described vertical mark 11 is used in simple mode, determines the length that will insulate before to wire insulation.This under the simplest situation can by the insulation before fixedly realizing; Described vertical mark 11 is used for check after insulation.
Fig. 2 represents from the observed terminal 5 of different lines of vision with Fig. 3.
Claims (4)
1. one kind is used to connect the electric lead of insulation and the terminal of electric switch (5), described electric switch has the housing (2 of electric insulation, 3), from this housing, stretch out the linkage section (4) of a conduction at least, be equipped with the lead of cable shoes especially to be fixed on the described linkage section by being threaded, wherein, described terminal (5) is fixed on this linkage section (4) in switch-side, and has hole (7 in the lead side, 8), the wire termination of described insulation inserts in this hole and by clamping device and fixes, it is characterized in that, be positioned at of described terminal (5) on the surface (10) in the outside and be provided with mark (11), this mark represents that described wire termination is being inserted into the length that will insulate before in described hole (7,8).
2. according to the described terminal of claim 1, it is characterized in that the wire termination of described insertion is clamped on the inwall of described hole (7,8) by a bolt (9) transverse to the longitudinal extension of described hole (7,8) in described hole (7,8).
