Technical Field

The utility model relates to the field of controllers, in particular to a controller with a fuse easy to replace.

Background

The controller is typically used for the connection of various sensors, equipment, including large, high power equipment such as a large mixer, injection molding machine, etc. These large high powers may cause the fuse to blow during operation for various reasons, which may require replacement of the fuse. Among the problems are: because the power units on the equipment are very many, the controller can integrate corresponding quantity of fuses, when one fuse is fused, searching for damaged fuses according to error reporting codes and circuit diagrams is very troublesome, and the working efficiency is affected; because of the number of fuses, the fact that a certain fuse is blown does not mean that the whole circuit is broken, and for safety reasons, the fuse can be replaced after the whole circuit is powered off, and the equipment can only be stopped, so that the working efficiency is seriously affected.

Disclosure of utility model

The utility model aims to provide a controller which is easy to replace a fuse.

In order to achieve the above purpose, the following technical scheme is adopted:

The utility model provides an easily change controller of fuse, includes the casing and installs circuit board on the casing, be provided with a plurality of binding post, socket and strongseat on the circuit board, be provided with a plurality of mounting holes in the strongseat, each be provided with two sets of wavy shell fragments that are used for centre gripping fuse both ends in the mounting hole, the shell fragment is two to be a set of, shell fragment electric connection in the circuit board, it has inserted a connecting seat to connect in the mounting hole, it is in to connect including the top cap with form be used for holding the crotch portion at fuse middle part under the top cap, each the other pilot lamp that is provided with of mounting hole, the pilot lamp with corresponding on the circuit the fuse is established ties.

Further, the four corners of the bottom of the shell are provided with grooves matched with the external guide rods. The housing is conveniently mounted in a rail/guide bar of an electric cabinet.

Further, the top cover is provided with a notch, and when the connecting seat is inserted into the mounting hole, the top cover is flush with the surface of the safety seat. When the connecting seat needs to be removed, the connecting seat can be taken out along the notch.

By adopting the scheme, the utility model has the beneficial effects that:

Based on the strongpoint of setting, when changing the fuse, only need according to the pilot lamp alright find the fuse of damage, then will directly take away the connecting seat and change, this process can not touch other fuses, and operation safe and reliable is swift, need not the outage, and the equipment that is connected can continue to work, has improved production efficiency.

Detailed Description

Exemplary embodiments that embody features and advantages of the present utility model will be described in detail in the following description. It will be understood that the utility model is capable of various modifications in various embodiments, all without departing from the scope of the utility model, and that the description and illustrations herein are intended to be by way of illustration only and not to be construed as limiting the utility model.

As shown in fig. 1-3, a controller for easily replacing a fuse includes a housing 1 and a circuit board 2 mounted on the housing 1, wherein the circuit board 2 is provided with a plurality of connection terminals 3, a socket 4 and a fuse holder 5, the fuse holder 5 is provided with a plurality of mounting holes, each mounting hole is provided with two groups of wavy spring plates 6 for clamping two ends of the fuse 7, the spring plates 6 are in a group, the spring plates 6 are electrically connected to the circuit board 2, a connecting seat 8 is inserted into the mounting holes, the connection includes a top cover 81 and a hook portion 83 formed under the top cover 81 for clamping the middle of the fuse 7, and an indicator lamp 9 is arranged beside each mounting hole and is electrically connected with the corresponding fuse 7 in series.

Four corners of the bottom of the shell 1 are provided with grooves matched with external guide rods. It is convenient to mount the housing 1 in the guide rail/guide bar of the electric cabinet.

The top cover 81 is provided with a notch 82, and when the connecting seat 8 is inserted into the mounting hole, the top cover 81 is flush with the surface of the safety seat 5. When the connection socket 8 needs to be removed, the connection socket 8 can be taken out along the notch 82.

Working principle:

Because pilot lamp 9 and corresponding fuse 7 establish ties on the circuit, after certain fuse 7 melts, corresponding pilot lamp 9 goes out, and the maintenance personal takes out connecting seat 8 along breach 82 from instrument (such as tweezers, electrography) according to this pilot lamp 9, because connecting seat 8's crotch portion 83 holds fuse 7, therefore also can be taken away by fuse 7, after connecting seat 8 installs new fuse 7, directly pack connecting seat 8 into the mounting hole, and the both ends extrusion contact of fuse 7 is shell fragment 6, realizes the electrical connection with circuit board 2.

The beneficial effects are that:

Based on the strongbox 5 that sets up, when changing fuse 7, only need according to pilot lamp 9 alright find damaged fuse 7, then will directly take away the change with connecting seat 8, this process can not touch other fuses 7, and operation safe and reliable is swift, need not the outage, and the equipment that is connected can continue to work, has improved production efficiency.

While the present disclosure has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration rather than of limitation.
