Abstract
The utility model discloses a thin type aluminium shell resistor which comprises an aluminium shell, a resistor core and two electrode leads, wherein the resistor core is composed of two mica plate frameworks and an alloy wire winding along the circumferential direction of the two mica plate frameworks, connecting terminals are arranged at the outer side faces of the two mica plate frameworks, both ends of the alloy wire are respectively connected with the two electrode leads by virtue of the connecting terminals, one mica plate framework is provided with a through hole, one end of the alloy wire passes through the through hole and is connected with one connecting terminal between the two mica plate frameworks. The thin type aluminium shell resistor provided by the utility model has the following beneficial effects: 1, by adopting mica plates as the frameworks to wind the alloy wire, the volume and weight are saved in comparison with a traditional resistor adopting a porcelain pipe framework; 2, one end of the alloy wire passes through the two mica plate frameworks and is connected with the connecting terminal, so that the inner space structure is used efficiently; 3, compared with an aluminium shell resistor with a same-power traditional construction, the volume of the thin type aluminium shell resistor disclosed by the utility model is saved by more than 50%.
Description
Technical field
The utility model relates to electronic devices and components field, particularly a kind of aluminum-housed resistor.
Background technology
Aluminum-housed resistor is generally by aluminum hull, skeleton, B alloy wire and contact conductor, existing aluminum-housed resistor is to adopt porcelain tube as skeleton, B alloy wire is wound on porcelain tube, because porcelain tube volume is larger, heavy, cause whole aluminum-housed resistor not only thick but also large, space, compared with the inconvenient use in circlet border, even cannot be used.
Utility model content
The purpose of this utility model be to provide a kind of light small and exquisite, be convenient to the slim aluminum-housed resistor installed, be particularly suitable for the little installation environment in space.
The purpose of this utility model is achieved by the following technical programs, slim aluminum-housed resistor, comprise aluminum hull, resistor core and two contact conductors, it is characterized in that, described resistor core is to form by two mica splitting frameworks and along the B alloy wire of its circumferential coiling, and the two ends of B alloy wire are connected with two described contact conductors respectively.
Further, the lateral surface of described two mica splitting frameworks is equipped with binding post, and the two ends of B alloy wire are connected with two described contact conductors respectively by binding post.
Further, wherein on a slice micarex skeleton, offer through hole, one end of B alloy wire is passed through hole and is connected with a binding post between two mica splitting frameworks.
Further, aluminum hull inwall arranges micarex insulating barrier, and quartz sand embedding is set between micarex insulating barrier and resistor core.
Beneficial effect: 1, adopt micarex as backbone winding alloyage silk, adopt porcelain tube skeleton to save volume and weight than tradition; 2, one end of B alloy wire between two mica splitting frameworks through being connected with binding post, effectively utilized interior spatial structure; 3, contrast with the aluminum-housed resistor of Same Efficieney traditional structure, the utility model is saved volume more than 50%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, slim aluminum-housed resistor provided by the utility model, comprise aluminum hull 6, resistor core and two contact conductors 1, resistor core is B alloy wire 4 formations by two mica splitting frameworks 8,9 and circumferentially coiling thereof, two mica splitting frameworks 8,9 lateral surface is respectively equipped with binding post 3,7, with snap ring, by micarex skeleton 8 and binding post 3, micarex skeleton 9 and binding post 7 riveted joints are fixing.On micarex skeleton 8, offer through hole 10, one end of B alloy wire 4 is connected with binding post 3, and the other end is through through hole 10 on micarex skeleton 8, and between micarex skeleton 8,9, interlayer is connected with binding post 7.The inwall of aluminum hull 6 arranges the 2 insulation isolation of micarex insulating barrier, resistor core is placed in the inner chamber of micarex insulating barrier 2 isolation, uses quartz sand 5 embeddings, and fix with resin-bonding between micarex insulating barrier 2 and resistor core.
Above-described embodiment is as preferred embodiments of the present utility model; describe technical conceive of the present utility model and essential implementation in detail; not that protection range of the present utility model is limited; all any simple modification of doing according to the utility model Spirit Essence and equivalent structure transformation or modification, within all should being encompassed in protection range of the present utility model.
