Embodiment
Fig. 1,2,2a and 4 partially illustrates modularization low-voltage circuit breaker, it to be intended to be installed on mounting guide rail R and the terminal B be provided with according to the utility model preferred embodiment, wherein, described terminal is intended to the inner conductor of circuit breaker to be electrically connected to electrical network or other modular electric devices.For this reason, the housing of circuit breaker comprises for two openings 1,2 close to this terminal, and they are intended to allow to insert two cables 3,4 respectively, and wherein, described cable is intended to engagement threads connecting elements 5 and the quick connecting elements 6 of spring respectively.
Same as shown in Fig. 3 and 3a, this terminal B comprises retainer C in a way known, it comprise limit have the opening 11 of almost parallel hexahedral shape four walls 7,8,9,10, described retainer C is arranged in the shell 12 be arranged in Shell of circuit breaker in a sliding manner, and described retainer is suitable for by the actuating screw 13 in one of wall being screwed into retainer by translation, and is mounted to rotate freely between the link position and open position of terminal relative to the housing of device.
This terminal also comprises U-shaped connection gasket 14, is intended to be electrically connected to the inner conductor of described device in its above-mentioned opening 11 being arranged on retainer C.Pin shape spring leaf 15 is arranged in this U-shaped pad, and this spring leaf comprises first end 16, and it is intended on so-called first leg 17 of the leg of the above-mentioned U being fixed on described pad; And free end 18, it can be supported on cable 4, this cable to be clamped in when such cable 4 is inserted in described terminal between another so-called second leg 19 and described free end 18 of spring leaf 15 of above-mentioned U.
Above-mentioned screw connection member 5 is formed primarily of so-called first leg 17 of the retainer C that can be driven by screw rod 13 and described pad, wherein, so-called first cable 3 is intended to be suitable for be clamped between retainer C and this leg 17 in the actuation process of screw rod 13 in closure.
Quick connecting elements 6 is formed, to be clamped between these two elements 15,19 by so-called second cable 4 primarily of this spring leaf 15 of second leg 19 of the U of the described pad of joint.
As Fig. 2,2a, 3 and 3a in more specifically shown in, two main walls 9,10 of retainer C face comprise two bolts (stud) 20,21 therein, it extends towards the inside of retainer C and is intended to combined spring sheet 15, to remove the patchhole 2 of so-called quick connecting elements 6 and to allow so-called second cable 4 of electrical connection, and be convenient to be removed, illustrated by inciting somebody to action below.
With reference to the accompanying drawings the operation of the terminal B according to above preferred embodiment is described.
In FIG, terminal B is in the position prepared for being inserted by cable 4 in the hole 2 that is connected with quick connecting elements 6.
In this position of terminal B, screw rod 13 has been threaded into and retainer C is in high position.Therefore, as shown in Figure 2, be necessary screw rod 13 of outwarding winding, this unthreading action translation retainer is towards mounting bracket, and this motion allows possible cable to be inserted into the hole of wanting d/d screw connection member to be connected.In order to remove the hole that is connected with quick connecting elements and allow cable to be inserted in this hole, be necessary pressure to be applied on spring leaf 15, to compress the latter.(Fig. 2 a) will be produced by screwdriver T or other instrument by user this pressure, and these instruments will be used for being pressed in screw head 13, to reduce retainer C on the direction of the fixed support R of this device.In this translation motion of retainer C, it will carry out compression spring leaf 15 by bolt 20,21, to allow to insert cable 4.
It is to be noted, by such fact, namely space e the diapire 8 of retainer C surperficial f be freely between the housing wall g of this diapire 8 relative, make retainer C to carry out this translation.
It should be appreciated that, once cable 4 is inserted into, and instrument T is removed, make it no longer apply on pressure and retainer C, then spring leaf 15 makes retainer C return along by existing on path for translation that so-called second cable 4 the limits direction before this device by bolt 20,21.
In reverse operating process, when user wants to remove the cable 4 be previously connected by quick connecting elements 6, first user will to be outwarded winding screw rod 13 by screwdriver T, and as in figures 2 and 2 a, this moves up first causing retainer C in the side of mounting bracket R.
This unthreading action only will allow to remove the cable be previously inserted in the hole be connected with screw connection member, and can not act on by any way on the cable that is inserted in these quick connecting elementss.
Therefore, again be necessary to be convenient to remove cable 4, to bring pressure to bear on screw head 13 by instrument T, this will cause translation retainer on the direction of mounting bracket R, and therefore carry out compression spring leaf by described bolt, to remove the opening be used for close to cable.
In the diagram, this terminal is in link position, engages quick connecting elements 6 and screw connection member 5 respectively for two cables 3,4.Therefore, retainer C has entered in high position after screw rod 13 is threaded into.In this position, between the diapire 8 that so-called first cable 3 is clamped at retainer C and so-called first leg 17 of the leg of U formed by connection gasket 14, and so-called second cable 4 is clamped between another so-called second leg 19 of the leg of spring leaf 15 and aforementioned U.
Therefore, the utility model provides a kind of doubly-linked direct type splicing ear, and it has simple design, for device is connected to one or two cable fast.
This terminal can be arranged on pre-wired devices all at present.Therefore, only may have this additional function can by using the single scope be added into according to one or more terminal of the present utility model.
In fact, easily can be made by the terminal that is threaded of standard according to this terminal of the present utility model, benefit from all advantages provided by the latter's terminal, wherein simultaneously, described quick connect system can optionally be added, or is removed subsequently as required.
It is to be noted, described screw connection member can receive two cables, instead of single cable, as has been described in the above embodiment.
Certainly, the utility model be not limited to only to provide in an illustrative manner address shown embodiment.
In contrast, the utility model comprises all technically equivalent ones and their combination of described component, and prerequisite is if these equivalents are produced in its spirit.
