Abstract
The utility model provides a three stratotype binding post, includes the casing be equipped with the mounting in the casing, the electric conductor, the three -layer the electric conductor sets up in the casing, the cage spring, the cage spring housing is established on the mounting, with fixed the electric conductor. The utility model discloses three stratotype binding post's thickness is only 5.2 millimeters, improved wiring density, and the high density wiring is extremely important under the limited circumstances in switchgear space. Simultaneously, the cage spring of increase sets up the arc breach at the side of spring leaf, utilizes the breach to reduce the width of strip shaped metal spring leaf to the distribution of adjustment elasticity increases the spring leaf end to the clamping -force of wire end, can effectively avoid the wire wire is not hard up in the course of the work droing.
Description
Technical field
The utility model relates to electric field, particularly relates to electrical connection, particularly a kind of three stratotype binding posts.
Background technology
Modular binding post is widely used in power supply circuits and connects.In prior art, the Wiring module that can be arranged on distribution box guide rail comprises insulation shell, inlet wire binding post and outlet binding post, inlet wire binding post and the conducting in insulation shell of outlet binding post.But conventional connections terminal is one-in-and-one-out formula, often three groups of circuits need three terminals, and not only use cost increases, and shared space is also three times of this product.
Utility model content
The purpose of this utility model be to provide a kind of reduce the three stratotype binding posts that take up space, reduce costs.
For solving the problems of the technologies described above, the utility model three stratotype binding post, comprises housing, in described housing, is provided with fixture; Electric conductor, three layers of described electric conductor are arranged in described housing; Cage spring, described cage spring is set on described fixture, with fixing described electric conductor; Wherein said cage spring comprises a bullion spring leaf, described bullion spring plate deflection also forms closed loop, the position of the contiguous end, one end of described bullion spring leaf is provided with a rectangle hole clipping, the other end of described bullion spring leaf is through described rectangle hole clipping, two side edge of one section of described bullion spring leaf within the scope of described closed loop are provided with first breach separately, utilize described first breach to reduce the width of described bullion spring leaf, thus the distribution of adjustment elastic force.
Described bullion spring leaf is provided with second breach separately within the scope of closed loop, with two side edge of described first breach place section another section in opposite directions, utilize described second breach to reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force.
Described first breach is circular arc.
Described bullion spring leaf forms an arc-shaped upper ends and an arc lower end after bending to closed loop, and the radius of curvature of described arc-shaped upper ends is greater than the radius of curvature of described arc lower end.
The thickness of the utility model three stratotype binding post only has 5.2 millimeters, improve wiring density, and high density wiring is very important when switchgear limited space.Simultaneously, the cage spring increased arranges arc notch at the side of spring leaf, utilizes breach to reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force, increase spring leaf end to the chucking power of conducting wire end, effectively can avoid the wire easy loose or dislocation of wire in the course of the work.

Fig. 1 is the utility model three stratotype binding post explosive view;
Fig. 2 is the utility model three stratotype binding post internal structure schematic diagram;
Fig. 3 is the utility model three stratotype binding post cage spring structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model three stratotype binding post is described in further detail.
As shown in FIG. 1 to 3, the utility model three stratotype binding post, comprises housing 8 and three layers of electric conductor, 7, the three layers of electric conductor 7 be arranged in housing 8 are fixed by the cage spring 6 be set on fixture 9 at its two ends respectively.
Wherein cage spring 6 is formed by a bullion spring plate deflection, closed loop is formed after bullion spring plate deflection, shape after bullion spring plate deflection comprises an arc-shaped upper ends 1 and an arc lower end 2, the position of the contiguous end, one end of bullion spring leaf is provided with a rectangle hole clipping 3, the rectangle hole clipping 3 that the other end of bullion spring leaf passes, two side edge of one section of bullion spring leaf within the scope of closed loop are provided with first breach 4 separately, the first breach 4 is utilized not reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force.
Further, bullion spring leaf is provided with second breach 5 separately within the scope of closed loop, with two side edge of the first breach 4 place section another section in opposite directions, utilize the second breach 5 to reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force.
Further, the first breach 4 is in circular arc.
Cage spring 6 utilizes breach to reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force, increase spring leaf end to the chucking power of conducting wire end, effectively can avoid the conductor easy loose or dislocation of wire in the course of the work.When especially connecting small bore conductor, owing to increasing the chucking power of conductor, even be in vibrations operational environment, also can guarantee the reliable connection of wire.
The thickness of the utility model three stratotype binding post only has 5.2 millimeters, improve wiring density, and high density wiring is very important when switchgear limited space.Simultaneously, the cage spring increased arranges arc notch at the side of spring leaf, utilizes breach to reduce the width of bullion spring leaf, thus the distribution of adjustment elastic force, increase spring leaf end to the chucking power of conducting wire end, effectively can avoid the wire easy loose or dislocation of wire in the course of the work.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the scope of the application.
