Abstract
The utility model provides a crown spring which comprises a crown spring body, wherein the crown spring body is formed by connecting a plurality of bow-shaped spring strips which incline toward the same side, the spring strip is composed of an elastic part used for being contacted with a conductive surface and extension parts connected to two ends of the elastic part, and the elastic part protrudes diagonally upward relative to the extension parts; the tail end of the extension part is provided with a contact pin, and the contact pin and the extension part are arranged with an included angle; the center lines of the contact pins at two ends of the spring strips on the crown spring body are not on the same axis; and the center distance of adjacent contact pins is 4mm. Compared with the prior art, the crown spring provided by the utility model has the advantages of long service life, wide application range and high overcurrent bearing capacity.
Description
Technical field
The utility model relates to the strong hat spring of good, the anti-contact displacement ability of a kind of electric conductivity.
Background technology
The hat spring is widely used in electrically conducting of electric connector.As a kind of hat spring that discloses in the Chinese patent 201220015427.5, its hat spring is dolioform, though can be used for transmitting big electric current, stability is good, and the anti-contact displacement ability of reed causes purposes limited, only at the conducting that is electrically connected of jack type.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of hat spring is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hat spring, comprise hat spring body, described hat spring body is formed by connecting by the arc spring bar that several tilt to the same side, and described spring bar is made up of the extension that is used for contacting the elastic portion of conducting surface and being connected the elastic portion two ends, and described elastic portion is protruding obliquely upward compared to extension;
Described extension end is provided with haptic element, is the angle setting between described haptic element and the extension; The center line of spring bar two ends haptic element is not on same axis on the described hat spring body;
The centre-to-centre spacing of adjacent haptic element is 2-6mm.
Preferably, the wide of spring bar is 35-40mm, and it is 1-3mm that described elastic portion is higher than extension, and the angle between described haptic element and the extension is 45 °.
Preferably, described spring bar is made of the silver-plated skin on beryllium copper bar internal layer and the coating beryllium copper bar internal layer.
The beneficial effects of the utility model are mainly reflected in: (1) long service life, and supportive, resilience and anti-contact displacement performance all are enhanced, and the spring bar is arranged closely can maximized increase conductive area.
(2) applied range, the utility model not only can be used for the electrical cnnector conducting of jack type, can also be applied to the conducting that is electrically connected of plane contact.
(3) reed adopts ectonexine structure, overcurrent ability to bear height.

Embodiment
The utility model has disclosed a kind of hat spring, as shown in Figures 1 to 4, comprises hat spring body, and described hat spring body is formed by connecting by several arc spring bars 1.
In conjunction with Fig. 2, Fig. 3, described spring bar 1 is made up of the extension 12 that is used for contacting the elastic portion 11 of conducting surface and being connected elastic portion 11 two ends, and described elastic portion 11 is protruding obliquely upward compared to extension 12.
Following as the utility model preferred embodiment, the while also can strengthen the anti-contact displacement ability of spring bar 11, and the wide of spring bar is 37.66mm, and described elastic portion 11 is than extension 12 high 2.03mm.
Described elastic portion 11 is formed slopely the contact-making surface that contacts with conducting surface to the same side on reed, when reed is closely arranged, and can maximized increase conductive area.When concrete the use, elastic portion 11 has formed support portion 15 with extension 12 junctions, and described support portion 15 can finely will be preced with spring and be supported on the conducting surface that described hat spring is fixed, and also can well be preced with contacting of spring and conducting surface.
In order to strengthen the overcurrent ability to bear of hat spring, described spring bar 1 is made of the silver-plated skin on beryllium copper bar internal layer and the coating beryllium copper bar internal layer.
Described extension 12 ends are provided with haptic element 14, and the centre-to-centre spacing of adjacent haptic element is 4mm.Being angle between described haptic element 14 and the extension 12 is 45 ° of settings; In order to make spring bar 11 in use can bring into play better support resilience force, prolong the life-span of resilience, the center line of spring bar two ends haptic element 14 is not on same axis on the described hat spring body; The two ends haptic element 14 that is spring bar 11 forms angled staggered oblique setting at hat spring body.
The utility model still has multiple concrete execution mode, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
