Abstract
The utility model provides a hub device transducer to make sure connection of transducer is more convenient and reliable, including hub base on transducer body and drawn-inserted hub header on the hub base, whereinseveral conductive columns and its conductive strip are fixed on hub base and hub header, and locking device which tightens cable terminals is fixed on the hub header, and thus connection will not be limited by small space of electrical control cabinet by means of that hub header is drawn out from hub base and then cable terminals are respectively inserted and locked into hub header. The hub device transducer ensures connection terminals are linked correctly with good contact to avoid transducer damage caused by man-made incorrect connection, and facilitates maintenance and overhaul for equipment. The utility model is mainly used for low-power transducer.
Description
Technical field
The present invention relates to a kind of frequency converter, relate in particular to a kind of frequency converter line concentrator.
Background technology
Frequency converter has been applied to the equipment speed governing since later 1970s, and four innovations of development differentiation experience through two more than ten years are widely used in daily production, various fields in life at present.For some low power frequency converters, it is installed in the electrical control cabinet usually, the result of making is like this: because the control cubicle space of small-sized machine is less, innerly install compactly, occur frequency converter major loop forceful electric power input connection error easily and the situation that causes frequency converter to burn; Also because the space is narrow and small, and operator's inconvenience is inserted the frequency converter input/output terminal reliably to each powered wire, control line cable joint, cause controlling inaccurate or effectiveness is not obvious and produce misoperation.
Summary of the invention
The purpose of this invention is to provide a kind of easy-to-connect, safe and reliable frequency converter line concentrator.
Technical scheme of the present invention is such: a kind of frequency converter line concentrator, comprise the line concentration base that is fixedly arranged on the transducer body and can dial the line concentration head of being located on the described line concentration base slottingly, described line concentration base and line concentration head are respectively equipped with some conductive poles and reach and the suitable conducting strip of each conductive pole, and described line concentration head is provided with the locking device that is used for fastening each cable terminal.
Above-mentioned frequency converter line concentrator, described conductive pole is located on the line concentration base, and described conducting strip is located on the line concentration head.
Above-mentioned frequency converter line concentrator, locking device comprise the rectangular metal frame of a hollow, and the side of described metal frame is provided with trip bolt, and metal frame also is connected with conducting strip simultaneously.
Above-mentioned frequency converter line concentrator, described conductive pole are located on the line concentration head, and described conducting strip is located on the line concentration base.
Above-mentioned frequency converter line concentrator, described locking device comprise the rectangular metal frame of a hollow, and the side of described metal frame is provided with trip bolt, and metal frame also is connected with conductive pole simultaneously.
The utility model changes traditional cable and frequency converter is imported, the direct-connected mode of output, but earlier each cable is connected with the line concentration head, the line concentration head is inserted on the line concentration base that is fixedly arranged on frequency converter again.The benefit of making is like this: one, in wiring, be not subjected to the restriction of electrical control cabinet small space, can from line concentration base, transfer to the line concentration head to come earlier, each cable terminal is inserted line concentration head and locking respectively, and easy to operate; Two are not subjected to spatial limitation during based on aforementioned wiring, make the operation of wiring can guarantee that each binding post wiring is correct, contact is good, help preventing artificially wrong and damage frequency converter, simultaneously also very convenient for the Maintenance and Repair of equipment.

The A-A cutaway view of connector lug among Fig. 3 Fig. 2.
Embodiment
With reference to figure 1, Fig. 2, Fig. 3, embodiment provides a kind of frequency converter hub 1, comprise the line concentration base 11 that is fixedly arranged on the transducer body and can dial the line concentration head of being located on the line concentration base 11 12 slottingly, described line concentration base 11 is provided with four conductive poles 111 and is respectively applied for three phase lines of connection and a ground wire, conductive pole 111 is cylindrical, its free end is used for being connected with conducting strip 121 on the line concentration head 12, and the other end of conductive pole 111 is connected on the circuit board of frequency converter.Line concentration head 12 is provided with conducting strip 121 that should four conductive poles 111, execute back when described conducting strip 121 is connected with conductive pole 111 pretightning force with guarantee conductive pole 111 and insert out in the middle of the conducting strip 121 easily and contact good.The other end of conducting strip 121 is connected with cable terminal 3 by locking device 2, in the present embodiment, described locking device 2 comprises the rectangular metal frame 21 of a hollow, the side of described metal frame 21 is provided with trip bolt 22, metal frame 21 also is connected with conducting strip 121 simultaneously, and an end of cable terminal 3 inserts in the metal frame 21, like this when rotation trip bolt 22, move on the metal frame 21, cable terminal 3 contacts reliably with conducting strip 121.For guaranteeing that line concentration head 12 and line concentration base 11 reliable contact preventing come off, on line concentration head 12, also be provided with hasp 123, hasp 123 is with after line concentration base 11 engages, and its most advanced and sophisticated barb hook is tightly believed line concentration base.
In the foregoing description, just the power line of frequency converter is integrated on the frequency converter electric wire connecting junction, mainly be to consider that the Frequency Converter Control line connects the less change in back, and the control line wrong is unlikely and burns frequency converter, in fact, it is in the purpose of this utility model, can all be integrated on the hub power line of frequency converter and control line, also can be integrated in the input cable of frequency converter on the hub, output cable is integrated on another hub, can certainly take other line concentration mode, its starting point is intended to make things convenient for wiring and guarantees that frequency converter is safe and reliable.
