Problems solved by technology

[0002] In the various known structural types of the fuse switch so far, there is such a problem mostly: when the operating slide plate is in the disconnected position or the replacement position, it is inconvenient to access the fuse tube, so take off the bad one or put it into a good one. Difficulty with the fuse tube

Embodiment Construction

[0045] The fuse switch according to the invention shown in Figures 1a, b has a housing 1 which consists of two housing halves 2, 3 which are fastened to each other by conventional connecting means such as screws or rivets.

[0046] In the front vertical wall 5, the housing 1 has a first hole 6 through which the first terminal wires of the electrical conductors to be monitored can be introduced into the housing 1, in the rear vertical wall 7 (see Figures 1b, 2, 3) A corresponding hole 8 is provided for the second terminal wire of the conductor to be monitored.

[0047] In addition, the front and rear end walls 5, 7 have a second hole 6', 8' for the introduction of the neutral connection wire.

[0048] As can be seen from Figures 2 and 3, there is a screw clamp 9 respectively behind the holes 6, 6 ', 8, 8 ' to clamp the bare end of the lug. These screw clamps can be constructed in any known manner, and the screw clamp 9 shown in the accompanying drawings is then, for example, m...

Abstract

The invention relates to a fuse switch comprising an insulating housing (1) in which two power conducting housing contacts (14) are fixed. Said switch further comprises a switch slider (22) that is also made of an insulating material and that is displaceably or pivotally guided between a switch-on position (Fig. 3 or Fig. 12) and an switch-off or replace position (Fig. 2 or Fig. 11) in the insulating housing (1), said switch slider receiving a fuse cartridge (20) whose end contact caps (21) (Fig. 3 or Fig. 12) are directly placed on the fixed housing contacts (14) in the switch-on position and are separated from the fixed housing contacts (14) in the switch-off or replace position (Fig. 2 or Fig. 11). Said switch also comprises a carriage (24) displaceably mounted in the switch slider (22) and holding the fuse cartridge (20), said carriage having a lug (27) engaging in a gate (28) mounted in the insulating housing (1). Said gate (28) is shaped in such a way that when the carriage (24) is displaced or pivoted, the latter is displaced at a distance such in relation to the switch slider (22) that the fuse cartridge (20) projects above the switch slider (22) in certain sections.

Description

technical field [0001] The invention relates to a fuse switch. This kind of fuse switch is used to control a fuse tube connected in series in a current-carrying wire, so that the current in the wire can be monitored by this fuse tube, and when the specified maximum value is exceeded, it will pass through the fuse located in the tube The fuse breaks the current. Background technique [0002] In the various known structural types of the fuse switch so far, there is such a problem mostly: when the operating slide plate is in the disconnected position or the replacement position, it is inconvenient to access the fuse tube, so take off the bad one or put it into a good one. There are difficulties with the fuse tube. [0003] DE-A1-2437509 describes a fuse circuit breaker of low-voltage high-capacity fuses. There is provided a low-voltage high-capacity bottom with two contacts into which the contact pieces of the fuse link can be inserted. The fuse link of this type of fuse is...
