The low-cost large electric current intermediate plate terminal of electric connector
Technical field
The utility model relates to a kind of electric connector intermediate plate terminal, specifically relates to a kind of electric connector with large electric current intermediate plate terminal.
Background technology
Electric connector is indispensable parts in electronic equipment, and application is more and more extensive, and electric connector form and structure are ever-changing, along with differences such as application, frequency, power, applied environments, the electric connector of various different structure forms is arranged.For the plug-in electric connector, adopt the plugged connection of easy operating to combine with firmly general screw mode, various parts are connected.In prior art, large electric current plug-in electric connector, for the large electric current wiring of all kinds of electric devices, mainly is comprised of male 4 and female seat 5, and male is inserted in female seat and removably connected by interface arrangment.In male, location is provided with large electric current intermediate plate terminal 6, and in female seat, location is provided with metal insert 3, and intermediate plate terminal and metal insert plug together the rear conducting that realizes plug-in electric connector circuit, as shown in Figure 1.
The intermediate plate terminal generally comprises the conductive plate 61 that is L-type and is U-shaped intermediate plate 62, intermediate plate comprises at the bottom of intermediate plate 621 and two elastic arms 622 being oppositely arranged, conductive plate comprises the first part 611 and second part 612 in succession in succession, first in succession the middle part of part with at the bottom of intermediate plate, be fixedly connected with, the opening of intermediate plate (metal insert inserts the entrance that intermediate plate connects) is second free end of part in succession dorsad, two elastic arms end of conductive plate dorsad form clamping part, for resilient clamp, insert the metal insert 3 in intermediate plate, form the conductive path of intermediate plate terminal and metal insert, as shown in Figure 2.
But existing intermediate plate terminal adopts integral type intermediate plate or finger-shaped intermediate plate usually, the integral type intermediate plate only has a bite, for some reason, there will be the inefficacy of intermediate plate terminal or conductive contact bad, thereby affects the reliability of electric connector electrical connection.And the integral type intermediate plate is when punch process is manufactured, usually can not guarantee that the elastic arm that intermediate plate two is relative is completely parallel, be offset even sometimes certain angle, while causing metal insert to insert intermediate plate, the contact-making surface of metal insert and intermediate plate terminal reduces, cause contact impedance to become large, product heats up higher, affects the electrical resistance of electric connector.Although the finger-shaped intermediate plate has had certain improvement aspect contact stabilization, conductive plate and the intermediate plate thickness of intermediate plate terminal are thicker usually, make the intermediate plate terminal sizes larger, and namely the volume of product is larger.Because having height, the common employing of intermediate plate terminal in prior art leads flexible conductive copper (phosphor bronze, beryllium copper), by the manufacture of metal plate punching processes, form, therefore, need to consume a large amount of height that has and lead flexible conduction copper material, and it is usually more expensive to have the price that height leads flexible conductive copper, cause the cost of whole electric connector product high.
