Abstract
The utility model discloses a kind of identifiable design measurement socket, can be identified and whether achieve electrical connection, also there is high insulation resistance, high withstand voltage characteristic simultaneously.Bottom the endoporus of barrel socket body, plug is installed, tubular is inserted the middle part of holding in both hands endoporus and is provided with jack, when plunger inserts jack body, plug inserts in jack thereupon, described jack body is positioned at described plug is slightly upper has installed U-shaped optoelectronic switch, infrared ray path is provided in order to give infrared emission tube and infrared receiver tube, described jack body is provided with a pair through hole, when plunger insertion jack body, plug insert in jack thereupon, plunger has blocked infrared ray, and infrared ray path is blocked.
Description
Technical field
The utility model relates to electrical measuring device, particularly relates to the measurement socket that can be identified and whether achieve electrical connection.
Background technology
Socket is electric testing instrument, instrument product (hereinafter referred to as product) indispensable ingredient, and it plays a part to connect outside test product and interiors of products metering circuit.Because the measuring object of product, measurement range or measurement parameter are different, the socket number be connected from the external world is also different, and some products only have a pair socket, and the product perhaps had has several to above socket.For the product having multipair socket, upgrading intelligent process in how to identify those numerous sockets actually that one (or several) have plug to insert, achieving electrical connection, to present technology, is not scabrous problem.But, require that the insulation resistance of socket is high and tolerate 10000V voltage again, again whether it is identified with regard to not a duck soup by use simultaneously.This situation will be run into relating in the high resistance measurement product about insulation measurement one class.Well-known insulation resistance is an electric parameter of insulating bodies, its order of magnitude minimum all 10
6more than Ω, the insulation resistance of general insulating material is large both 10
7Ω-10
9Ω scope; The insulation resistance of good insulating material can up to 10
10to 10
13Ω, what concept does is this? lift a simple case: under normal circumstances, its insulation resistance connect between the circuit of power frequency supply and its shell is only about tens Ω (10 to general Electrical Measuring Instrument
7Ω-10
8between Ω) just qualified.In fact the insulation resistance of a variety of materials all than the insulation resistance in above-mentioned example large hundred times, thousand times even higher.When wanting the insulation resistance of these materials of Measurement accuracy, the insulating property of product self just can not be poor, and a bottom line order of magnitude higher than product to be tested, comprises socket and must have high insulation resistance.Meanwhile, when the insulation resistance of product to be tested is high, test voltage also increases thereupon greatly.Now, the test voltage of some product is increased to 10000V.A socket is made to have superelevation insulation resistance and high withstand voltage properties, simultaneously again can be self-evident by its degree of difficulty of reliable recognition.This has become the difficult problem that this type of measures high resistant, superelevation resistance intelligent product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of identifiable design measurement socket, can be identified and whether achieve electrical connection, also has high insulation resistance, high withstand voltage characteristic simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: be provided with plug bottom the endoporus of barrel socket body, tubular is inserted the middle part of holding in both hands endoporus and is provided with jack, when plunger inserts jack body, plug inserts in jack thereupon, described jack body is positioned at described plug is slightly upper has installed U-shaped optoelectronic switch, infrared ray path is provided in order to give infrared emission tube and infrared receiver tube, described jack body is provided with a pair through hole, when plunger inserts jack body, when plug inserts in jack thereupon, plunger has blocked infrared ray, infrared ray path is blocked.
Preferably, described barrel socket body is increased and tubular inserts the axial dimension of handful to strengthen creepage distance.
Preferably, the outer wall inserting handful at described barrel socket body and tubular is equipped with annular groove to increase the path of surface leakage.
Preferably, described jack body and slotting handful all adopt teflon to make.
The beneficial effects of the utility model are, when designing jack body and plunger profile, add the axial dimension of part as far as possible, also annular groove is set on its cylindrical shell, thus effectively increase may along the path of surface leakage, indirectly add insulation resistance, also have very large benefit to raising voltage breakdown simultaneously; Jack is by the middle part of the deep endoporus being arranged on plunger, and under just completely avoid abnormal condition, charged electrode is likely to the electric shock of operating personnel; Make the material of processing parts owing to adopting teflon thus increased substantially the insulation resistance of socket entirety; The range of movement of plunger is very large, makes optoelectronic switch reliably can provide coherent signal, reduces the generation of wrong identification; Thus the intelligentized upgrading of this type of high resistant test products is carried out smoothly.
Accompanying drawing explanation
Accompanying drawing is the structural representation of identifiable design measurement socket.
In figure: 1-jack body; 2-plug; 3-U type optoelectronic switch; 4-through hole; 5-plunger; 6-jack; 7-outside lead; 8-inner lead; 9-nut.
Embodiment
As shown in drawings, plug 2 is fixed on bottom the endoporus of jack body 1 by nut 9, and inner lead 8 is welded on the afterbody of plug 2; The middle part of plunger 5 endoporus is installed with jack 6, and outside lead 7 is welded on the rear portion of jack 6; U-shaped optoelectronic switch 3 is stuck in the groove of jack body 1 outside, is in Shao Shang position, jack 6 top, in order to avoid stopping the infrared ray of U-shaped optoelectronic switch 3, jack body is provided with a pair through hole 4; When plunger 5 socket body 1 makes plug 2 contact and inserts jack 6, achieve the electrical communication of inner lead 8 and outside lead 7, plunger 5 has blocked infrared ray simultaneously, makes U-shaped optoelectronic switch 3 produce corresponding identification signal.The axial dimension that barrel socket body 1 and tubular insert handful 5 should increase to strengthen creepage distance as far as possible; The outer wall inserting handful 5 at barrel socket body 1 and tubular can also arrange annular groove to increase the path of surface leakage; Jack body 1 and slotting handful 5 all adopt teflon to make.
Claims (4)
1. an identifiable design measurement socket, bottom the endoporus of barrel socket body, plug is installed, tubular is inserted the middle part of holding in both hands endoporus and is provided with jack, when plunger inserts jack body, plug inserts in jack thereupon, it is characterized in that, described jack body is positioned at described plug is slightly upper has installed U-shaped optoelectronic switch, infrared ray path is provided in order to give infrared emission tube and infrared receiver tube, described jack body is provided with a pair through hole, when plunger inserts jack body, when plug inserts in jack thereupon, plunger has blocked infrared ray, infrared ray path is blocked.
