Abstract
The utility model belongs to spring technical field, in particular to a kind of contact spring, comprise spring body, be positioned at the welding ends of described spring body one end and be positioned at the contact jaw of the described spring body other end, the second spring section that described spring body comprises the first spring section and connects as one with described first spring section.Welding ends of the present utility model is connected closely with wiring board, there will not be the situation of loose contact, increases its useful life; In addition, because the utility model does not arrange sheet metal, reduce materials cost.
Description
Technical field
The utility model belongs to spring technical field, particularly a kind of contact spring.
Background technology
Full-automatic or semi-automatic production equipment is replaced manual operations by industrialized production.Contactor refers to and utilizes coil to flow through current induced magnetic field, makes contact closure, to reach the electrical equipment of control load.Because fast shut-off can exchange with direct current major loop and the device with big current control circuit can be connected continually, so often apply to motor as control object, also can be used as controlling the electrical loads such as shop equipment, electric heater, machine-tool and various kinds electric power unit, and as remotely controlled plant.Contact spring on contactor is to being located between two contacts, and helping when the magnetic field force for producing in ferrous is inadequate threads off uses.
As shown in Figure 1, the contact spring of prior art comprises spring body 100, the welding ends 200 be connected with described spring body 100 one end, the sheet metal 300 of riveting with described spring body 100 other end, and described spring body 100 is cylindrical helical structure.And said structure exists following problem: 1) welding ends is connected shakiness with wiring board, easily there is the phenomenon of loose contact; 2) useful life is not long; 3) due to the setting of sheet metal, the materials cost of contact spring is increased.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provides a kind of contact spring, and the welding ends of this contact spring is connected closely with wiring board, there will not be the situation of loose contact, increases its useful life; In addition, because above-mentioned contact spring does not arrange sheet metal, materials cost is reduced.
For achieving the above object, the technical solution of the utility model is:
A kind of contact spring, comprises spring body, is positioned at the welding ends of described spring body one end and is positioned at the contact jaw of the described spring body other end, the second spring section that described spring body comprises the first spring section and connects as one with described first spring section.
One as contact spring described in the utility model is improved, and described first spring section is set to cylindrical structural, and described second spring section is set to pyramidal structure.
One as contact spring described in the utility model is improved, and described first spring section is made up of the bung flange layer around five circles, and the diameter of each bung flange layer is 3.5 ~ 4.5mm; Described second spring section is made up of the bung flange layer around seven circles, and the diameter of outermost bung flange layer is 9.5 ~ 10.5mm.
One as contact spring described in the utility model is improved, and described contact jaw is set to circular configuration, and the diameter of the diameter of described contact jaw and the outermost bung flange layer of described second spring section is suitable.
The beneficial effects of the utility model are: the utility model comprises spring body, be positioned at the welding ends of described spring body one end and be positioned at the contact jaw of the described spring body other end, the second spring section that described spring body comprises the first spring section and connects as one with described first spring section.Welding ends of the present utility model is connected closely with wiring board, there will not be the situation of loose contact, increases its useful life; In addition, because the utility model does not arrange sheet metal, reduce materials cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is one of structural representation of the present utility model.
Fig. 3 is structural representation two of the present utility model.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figures 2 and 3, a kind of contact spring, comprise spring body 1, be positioned at the welding ends 2 of spring body 1 one end and be positioned at the contact jaw 3 of spring body 1 other end, the second spring section 12 that spring body 1 comprises the first spring section 11 and connects as one with the first spring section 11.
The contact spring elastic force of said structure composition is good, long service life; Reason is: spring body 1 of the present utility model adopts the first spring section 11 of different size and structure and the second spring section 12 to form, first spring section 11 is set to cylindrical structural, first spring section 11 is made up of the bung flange layer 13 around five circles, and the diameter of each bung flange layer 13 is 3.5 ~ 4.5mm; And the second spring section 12 is set to pyramidal structure, the second spring section 12 is made up of the bung flange layer 13 around seven circles, and the diameter of outermost bung flange layer 13 is 9.5 ~ 10.5mm.
Preferably, contact jaw 3 is set to circular configuration, realizes bump contact, and the contact of the iron plate of hinge structure, improves the efficient of contact, and saves and use material cost; The diameter of the diameter of contact jaw 3 and the outermost bung flange layer 13 of the second spring section 12 is suitable, realizes of the present utility model being symmetrical arranged, serves the effect of balance in use, enhance stability.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement of every those skilled in the art done by basis of the present utility model, replacement or modification all belong to protection range of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
