Description

Terminal block with safety and dust reduction capability

One, technical field:

The utility model relates to a kind of power patch panel, but relates in particular to a kind of safe and convenient to use and dustproof terminal block.

Two, background technology:

Press, shown in Figure 1 is a kind of schematic appearance of power patch panel, is positioned at the place that convenient plug is planted mostly, and therefore, the child is easy to touch terminal block, and the anxiety of safety is arranged.For this reason, many capping plate C and jack B covered of planting in the jack B of terminal block A get an electric shock to prevent the child from contacting.But it is very inconvenient that this method is used, in the time will use terminal block, must pull down capping plate C earlier and store in other so that re-use next time.Yet capping plate C is a kind of gadget, in the time will using, often can not find again, and is easy to forget embedding capping plate C because of carelessness, causes security breaches.Therefore, for the terminal block of frequent use, covering jack with the capping plate is not convenient act.

So, there is the people release mechanism to be set in terminal block A inside, so that jack B can not directly communicate with the inner conductive sheet, utilize the promotion or the rotation of elements such as push rod, latch or spring during use again, make conducting strip and jack B be conducting state and can use.Yet this method will change the position or the structure of former conducting strip, therefore power supply be connected can produce adverse influence on the contrary, even safety is played negative effect.In addition, in terminal block A, release mechanism is set, certainly will increases the inconvenience of assembling aspect, and will make the size change of terminal block A or the terminal block volume is increased.Therefore, the also non-perfect act of this method.

Referring to figs. 2 and 3 shown in, a kind of commercially available terminal block D is provided with a transverse groove d2 in its positive and negative electrode jack d1 position and is provided with an opaque disk d3 movably on transverse groove d2, promotes opaque disk d3 and moves to left or move to right, and can make jack d1 be the state that opens or closes.Yet still there are following two defectives in this structure:

1, opaque disk d3 only can hide positive and negative electrode jack d1, and can not hide earth polar jack d4, so the child then still has the anxiety of electric shock if insert metalwork by earth polar jack d4, and dust also can infiltrate by earth polar jack d4, and can not realize preventing dust.

2, as shown in Figure 3; the opaque disk of top jack is " opening " state when moving to right, and the opaque disk d3 of middle jack moves to left and is " passs " state, and the user is difficult to this jack of resolution really with naked eyes and studies carefully that to compete to be " opening " still be " pass "; not only use inconvenience, and regular meeting there is careless omission and potential safety hazard occurs.

Shown in Figure 4 is the outside drawing of another kind of commercially available terminal block, though be provided with the opaque disk e3 that can cover three jacks fully on its jack, but when opaque disk e3 be " opening " or " passs " time, same very difficult with the naked eyes identification, so use still has inconvenience.

Fig. 5 and Fig. 6 are the enlarged diagrams of one group of jack among Fig. 4, and three jack e1 of its positive and negative electrode and earth polar position is provided with transverse groove e2 has three corresponding jacks with installation opaque disk e3; Therefore opaque disk e3 needs to move to b one distance W by a and it could be covered; When opaque disk e3 moves to the right side of Fig. 6 by the left side of Fig. 5, be about to three jack e1 and cover and make it be " pass " state.The advantage of this structure is that three electrode jack e1 all can cover, and takes a step forward than Fig. 2, Fig. 3; But find when using that can embed smoothly in the transverse groove e2 for making opaque disk e3, the blocking projection e4 of its both sides can not be too big, otherwise can't embed; And the opaque disk e3 after embedding is as by the arrow F direction application of force, then can smoothly opaque disk e3 be pushed into right positions shown in Figure 6, but as application of force orientation deviation slightly, as F1 or F2 direction or position, then opaque disk e3 very easily is offset or rotates and breaks away from transverse groove e2.

So far, how to make opaque disk can effectively cover three electrode jacks, and make its difficult drop-off and easy operating and identification, be the problem that the utility model institute desire solves.

Three, summary of the invention:

The purpose of this utility model promptly is to provide a kind of to be had safe and dustproof effect and operation and uses all terminal block very easily.

To achieve these goals, the utility model utilizes shell and opaque disk to constitute a kind of terminal block.The surface of shell is provided with a plurality of electrode jacks that are used to insert electrode plug, and electrode jack frame face relative edge respectively is preset with fixing frame, and the madial wall of two frames is parallel to each other and be provided with chute; Opaque disk is provided with and the corresponding jack of shell electrode jack, and its both sides are respectively equipped with big or small clip corresponding to frame, and big or small clip embeds in the two frame madial wall chutes respectively and can slide therein, and its root edge convexes with a horizontal guide rail; Shell between the electrode jack is provided with the guide groove that is used to embed guide rail, and its length is greater than rail length.

Based on above structure, promote opaque disk and can make itself and two frames be complete frame face and make jack be opening and available; Or make itself and two frames be non-complete frame face and make jack be closed condition, not only safety but also can prevent dust.

Be described in further detail below in conjunction with the technical characterictic of specific embodiment the terminal block that the utlity model has safety and dust reduction capability.
