Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Fig. 1 is the socket cutaway view of connector of the present invention, Fig. 2 is the enlarged drawing of part A in Fig. 1, this connector is used for being connected with current transformer, shown in composition graphs 1 and Fig. 2, this connector comprises socket 4 for being electrically connected with Current Transformer Secondary terminal and the plug (not shown) suitable with described socket, this one end of plug is used for being electrically connected with other equipment, in the present embodiment, this one end of plug is connected with controller, by this connector, the current transformer in on-pole switch body is connected with controller.Be provided with contact pin 1 in socket 4, described contact pin 1 is plugged on contact pin fixed head 7, and wherein multiple contact pin is for accepting Current Transformer Secondary electric current.Contact pin for accepting Current Transformer Secondary electric current comprises root and head, and root is connected with head and root diameter (RD) is less than head diameter size.Being arranged with an insulating case 5 at the root of the contact pin for accepting Current Transformer Secondary electric current, being arranged with a spring 3 outside insulating case 5, this spring 3 is preferably cylindrical spring.A short circuit sheet 2 is socketed between the contact pin for accepting Current Transformer Secondary electric current, this short circuit sheet 2 with arrange for the pins normal accepting Current Transformer Secondary electric current, be set on the contact pin root contact pin root adjacent with pin head, the through hole passed for contact pin root is provided with in short circuit sheet, diameter due to through hole is less than pin head diameter, and thus pin head can not pass this through hole.One end of spring 3 abuts with contact pin fixed head 7, and other one end of spring 3 abuts with short circuit sheet 2.When socket is separated with plug, short circuit sheet 2 is under the elastic force effect of spring 3, be positioned at contact pin root one end near pin head, and be positioned at the outside of insulating case 5, make other conductive portions contact outside insulating case 5 on short circuit sheet 2 and contact pin, thus electrical connection is realized by short circuit sheet 2 between multiple contact pin 1 for accepting Current Transformer Secondary electric current, as shown in Figure 3.
Be provided with groove 6 at the root of contact pin, insulating case 5 is set in groove 6, and insulating case 5 overall diameter is less than or equal to the diameter of through hole on short circuit sheet 2.
When plug does not insert socket 4, short circuit sheet 2 is under the elastic force effect of spring 3, be positioned at the outside of insulating case 5, by short circuit sheet 2, contact pin is electrically connected with contact pin, thus ensure that corresponding secondary wiring of current mutual inductor terminal is in short circuit state, ensure that Current Transformer Secondary can not be opened a way.When the plug insertion socket 4 of connector, short circuit sheet 2 is under the thrust of plug, be pushed on the insulating case 5 of the root of socket 4, because the insulating case 5 arranged at the root of socket 4 current terminal contact pin 1 is non-conductive, short circuit sheet 2 is in electrical separation state between contact pin, ensure that the unimpeded of the current circuit between socket 4 and plug.
This connector construction is simple, easy to manufacture, simple and reliable process, can thoroughly solve current transformer (i.e. on-pole switch body) with controller (line feed terminals) though between because of which kind of reason separate and cause Current Transformer Secondary to open a way and produce the phenomenon of high pressure.This connector is simple to operate, safe and reliable, plays a good protection safely to the Installation and Debugging of current transformer.The mode structure of this current terminal contact pin separate type automatic short circuit, may be used on current circuit occasion widely.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
