Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " vertically ", " laterally ", " on ", D score, " preceding ", " back ", " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", close the orientation of indications such as " outward " or position is based on orientation shown in the drawings or position relation, only be the utility model and simplification description for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.
Referring to Figure 1 and Figure 2, the binding post that the utility model provides mainly comprises: base plate 3 and conductive pole 5.Base plate 3 is provided with through hole, and conductive pole 5 passes the through hole on the base plate 3.Simultaneously, be provided with sinter layer 6 in the through hole, so that conductive pole 5 is sealed on the base plate 3, better seal can be carried out by sinter layer 6 in the slit between base plate 3 and the conductive pole 5 like this, and then can reduce the influence that parts that the binding post two ends connect are subjected to binding post.And, the end face of base plate 3 and bottom surface are provided with ceramic layer 2 being positioned at the through hole, being come with air insulated in sinter layer 6 surfaces, ceramic layer 2 is insulating barrier, so ceramic layer 2 can make sinter layer 6 avoid external influence, and the insulating properties of sinter layer 6 and ceramic layer 2 can be avoided the short circuit between base plate 3 and the conductive pole 5, also can reduce binding post and be subjected to extraneous interference.
Being used for can be for multiple with sinter layer 6 surfaces and the shape of the ceramic layer 2 of outside air isolation, and preferably, ceramic layer 2 is the bowl dress, better sinter layer 6 is isolated from the outside out.The thickness of ceramic layer 2 is preferably 2-5mm.Sinter layer 6 is preferably the glassy layer of sintering, and it can have good insulation and sealing, and its cost is lower.In order not only to guarantee the sealing of sinter layer 6 but also can reduce cost that the thickness of sinter layer 6 is preferably 2-10mm.
The binding post that the utility model provides can be used for the various products that two parts need be electrically connected, especially at the binding post of high pressure, and for example in electric automobile, the high tension terminal that extraneous high-voltage power-line is electrically connected with compressor.Because high-voltage power-line mostly is three-phase electricity greatly, so the through hole on the base plate 3 is at least three, conductive pole 5 also is at least three, inserts compressor with the three-phase alternating current with high pressure.
Refer again to embodiment illustrated in fig. 2ly, binding post is owing to insert vehicle-mounted motor compressor with high voltage source among this embodiment.This embodiment is the binding post that has three conductive poles 5.And in the preferred embodiment, binding post comprises that also described first conducting strip 1 is fixed in an end of described conductive pole 5 for first conducting strip 1 and second conducting strip 4 that connect extraneous conducting end, and second conducting strip 4 is fixed in the other end of described conductive pole 5.First conducting strip 1 can be fixed on the binding post by common modes such as welding.First conducting strip 1 is used for an end of binding post is electrically connected with extraneous high-voltage power-line, and other the conducting end of needs electrical connection of high-voltage power-line or the external world can be fixed on first conducting strip 1 by modes such as welding.In order to strengthen being electrically connected of conducting end and first conducting strip 1, first conducting strip 1 is provided with first fixing hole 11 or first boss.In like manner, second conducting strip 4 is used for the other end of binding post is electrically connected with extraneous, for example is electrically connected with the motor terminal of compressor, and, preferably, in order to strengthen being electrically connected of extraneous conducting end and second conducting strip 4, second conducting strip 4 is provided with second fixing hole 41 or second boss.Wherein, be used for first boss of reinforcement connection and the structure of second boss and can adopt various structure well known to those skilled in the art.Above-mentioned extraneous conducting end is binding post two parts that need connect or the electric connecting terminal of product, and it can also can be other the terminal of conduction for lead.What deserves to be explained is that for the ease of binding post is fixed on other parts, base plate is preferably metallic plate, so that the steadiness of its installation and installation.
In embodiment illustrated in fig. 2, conductive pole 5 passed base plate 3 after, the sintered glass layer arranges ceramic layer 2 in base plate 3 upper and lower surfaces again and is isolated from the outside out with the glassy layer surface with the through hole with conductive pole 5 and base plate 3 sealings in the through hole of base plate 3.After binding post assembles, be fixed on the compressor, the terminals of the extraneous power line of first conducting strip, 1 welding of binding post, second conducting strip 4 of binding post patches motor terminal, thereby can make being electrically connected of compressor external circuit and casing motor internal, and its insulation resistance is better, and the sealing of binding post and compressor case connecting portion is better.In order to strengthen the sealing that binding post is connected with motor terminal, the pad of sealing is set between binding post and the motor, the pad middle part arranges the twice groove structure, the structure of combination seal circle plays dual-seal again, when loading onto high tension terminal, with screw it is locked on pad and the motor.The binding post assembling of said structure is simple, solved in the conducting process of high-tension electricity withstand voltage and with the problem of compressor insulation, simultaneously with glassy layer, ceramic layer 2, and gasket seal guaranteed the sealing of binding post, whole assembling process is simple, all more stable after product itself and the assembling thereof, can normally move at the electric type product, satisfy high-tension electricity demand and the better seal demand of compressor.
In sum, the binding post that the utility model provides is simple in structure, cost is lower, the assembling is simple and convenient, and it has good insulation and sealing.
In description of the present utility model, unless otherwise prescribed and limit, need to prove that term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be directly to link to each other, and also can link to each other indirectly by intermediary, for the ordinary skill in the art, can understand the concrete implication of above-mentioned term as the case may be.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
