Abstract
The invention relates to the field of electric connectors, in particular to a wire spring type elastic contact. The wire spring type elastic contact comprises two contact terminals at two ends and an elastic part connected between the two contact terminals. The elastic part comprises at least an inner layer of spiral spring and an outer layer of spiral spring, and two ends of at least the outermost layer of spiral spring are respectively fixedly connected with the corresponding contact terminals. By the arrangement, the wire spring type elastic contact has the advantages that the elastic contact is structurally equivalent to that multiple spiral springs are stacked on the same axis, so that small deformation of the elastic part can provide large elastic force, material requirements of the spiral springs can be lowered, and contact manufacturing cost is lowered; meanwhile, the stacked spiral springs inevitably generate multi-point contact, so that contact inductance can be lowered.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of wire spring type resilient contact.
Background technology
Electric connector is the common components of electric signal transmission, and be not only in industries such as communication, electric power transfer, nowadays it all obtain and apply very widely in the fields such as space flight and aviation.In the occasion that some are special, not adopt conventional inserting mode between the contact of electric connector, but the mode transmission of electric signals that the elasticity pressure adopted is touched, this type electric connector is often for the switching of the signal of telecommunication, it comprises panel, and panel is provided with penetrating installing hole, the contact of installing hole Elastic, the two ends of contact form contact site respectively, contact and realize the switching of the signal of telecommunication when in use with component elasticity such as the conductive plates of mating electrical connector.
Above-mentioned in the electric connector of signal converting, conventional contact type mainly contains following three kinds: 1, C type; 2, V-type; 3, spiral type (line spring type).The structure of C shape contact as shown in Figure 1, it arc-shaped contact part comprising two ends place and the connecting portion be connected between two contact sites, connecting portion is substantially in tabular, when in use, there is the crossover position place of position often between contact site and connecting portion of elasticity shape plate, deformation position is not only few, and deformation range is less, is therefore easy to the problem occurring fatigue damage; As shown in Figure 2, it is be contact site with two ends to the structure of V-type contact equally, compares to above-mentioned V-type contact spring, and its deformation position is in use more concentrated, and deformation range is less, is therefore also more prone to fatigue damage; Helix-style contact part does not adopt the slice structure of above-mentioned C type, V-arrangement contact, therefore useful life is relatively long, but it but has high requirement to material, common common copper material often can not provide enough elastic contact force, and the loop inductance of helix-style contact part is comparatively large, be unfavorable for the high-quality transmission of signal.
Known by describing above, the contact of reed-type also exists the problem of fatiguability damage, although helix-style contact part overcomes the fatigable problem of reed-type contact, but too harsh to the requirement of material, there is the problem that manufacturing cost is high.
Summary of the invention
The object of the present invention is to provide a kind of wire spring type resilient contact, to solve the problem that spiral type resilient contact is harsh to material requirements, manufacturing cost is high.
In order to solve the problem, wire spring type resilient contact of the present invention is by the following technical solutions: wire spring type resilient contact, two contacts comprising two ends and the elastic portion be connected between two contacts, elastic portion comprises helical spring, the helical spring of elastic portion has at least inside and outside two-layer, is at least positioned at outermost helical spring and is fixedly connected with corresponding contact respectively by two ends.
The adjacent two helical spring rotation directions of elastic portion are contrary.
Contact with each other between adjacent two helical springs of elastic portion and be slidably matched.
Each helical spring of elastic portion is fixedly connected with corresponding contact respectively by end.
The helical spring of the elastic portion of wire spring type resilient contact of the present invention has at least inside and outside two-layer, and be at least positioned at outermost helical spring to be fixedly connected with corresponding contact respectively by two ends, this is actually and is equivalent to be superimposed upon by multiple helical spring on same axis structure, make the less deformation quantity of elastic portion can provide larger elastic force thus, thus the requirement of helical spring to material can be reduced, reduce the manufacturing cost of contact, simultaneously, the helical spring be superimposed can produce Multi-contact unavoidably, thus the effect reducing contact inductance can also be produced.

Embodiment
The embodiment of wire spring type resilient contact, as Figure 4-Figure 6, two contacts 11 that this wire spring type resilient contact comprises two ends and the elastic portion 12 be connected between two contacts 11.
Contact 11 is in hemisphere, and its spherical outside surface defines for contacting with the contact of intermateable connector the contact-making surface conducted electricity, and the structure of contact 11 is identical with the structure of contact terminal of helix-style contact part of the prior art, and it will not go into details herein.
Elastic portion 12 is between two contacts, in wire spring type resilient contact, the effect of elastic portion 12 mainly contains two, one be as two contacts 11 between conductor, transmission of electric signals between two contacts 11, two is for contact 11 provides precompression with contacting of intermateable connector contact, ensures the reliability of contact.From the above-mentioned explanation to elastic portion, elastic portion 12 not only will have good conductivity, also wants to provide enough elastic forces.Elastic portion 12 comprises helical spring, in the present embodiment, the helical spring of elastic portion has inside and outside two-layer, be defined as internal layer helical spring 121 and outer helical spring 122 herein, two-layer helical spring is nested together and is coaxially set, and this is equivalent to two helical springs to be superimposed upon on same axis, makes the less deformation quantity of elastic portion can provide larger elastic force thus, thus the requirement of helical spring to material can be reduced, reduce the manufacturing cost of contact.Two helical springs are fixed together respectively by respective corresponding end and contact.Wherein two helical spring rotation directions are contrary, are to make two springs form network structure, increasing the contact point of the two like this, thus improve contact inductance, be in order to above-mentioned purpose equally, in the present embodiment, contact with each other between two helical springs and be slidably matched.
In other embodiment of wire spring type resilient contact, the helical spring quantity of elastic portion can also be two or more, and each helical spring is coaxially successively nested together, and in such cases, adjacent helical spring rotation direction can be made contrary; In addition, two of above-described embodiment Elastic portion helical spring rotation directions can also be identical; Also can only the outermost helical spring of line spring contact be connected with contact.
