Description
Technical field
The present invention relates to a kind of electric connector, be specifically related to a kind of spring economizing type electric connector.
Background technology
Electric connector can quickly realize electric wire and electric wire, electric wire and circuit board and circuit board and electricity
The connection of road plate, is indispensable parts in electronic equipment, and application is more and more extensive,
Electric connector form and structure are ever-changing, along with application, frequency, power, application ring
The differences such as border, have the electric connector of various different structure form.Between electric connector and electric wire
Connected mode mainly have screw type, spring, puncture wire insulation skin, wire terminations colds pressing end
The modes such as son.At present, spring electric connector is widely used to world electrician and electronic engineering
Industry, such as, illumination, elevator lifting control, instrument and meter, power supply, chemistry and automobile are dynamic
Power etc..
Spring electric connector generally includes plastic body, conducting terminal and spring leaf, spring leaf with lead
Electric terminal is located by connecting, and the elastic arm of spring leaf and conducting terminal Elastic Contact.Conducting terminal
It is fixed in plastic body with spring leaf, plastic body is provided for connect the entrance hole of wire
With a sub-aperture, play sub-aperture connection elastic arm, entrance hole connection elastic arm and the elasticity of conducting terminal
Contact position.When spring electric connector connects wire, bottle opener is utilized to insert sub-aperture driving spring
The elastic arm of sheet, makes elastic arm
Unclamp from conducting terminal, then, wire is inserted contact conducting terminal from entrance hole；Last pine
Opening son, the elastic arm resilience of spring leaf pushes against wire and conducting terminal, thus realize wire with
Conducting terminal connects conducting.But, in prior art, spring leaf 3 is the most C-shaped, and conducting end
Son 2 generally uses a piece of metal plate punching to form the terminal structure of semi-surrounding c-type spring leaf, sees figure
1, the conducting terminal of this structure all uses sheet metal to fence up, after flattening due to three faces
The area of sheet material is the biggest, it is therefore desirable to consumes substantial amounts of conductive material, thus causes spring electricity
Connector product relatively costly, and it is not suitable with the development trend of energy-saving and emission-reduction.
