Description
[technical field]
The utility model is about a kind of electric connector, refers to a kind of electric connector that electrically connects wafer module and circuit board that is mainly used in especially.
[background technology]
The existing electric connector that is used to electrically connect wafer module and circuit board, generally have lamellar and be connected to the insulating body of circuit board, this insulating body middle part is a conduction region, be equipped with plurality of conductive terminals in conduction region, this conducting terminal generally has better elastic and is stretched on outside the insulating body, when being connected with wafer module and circuit board, by being applied one, electric connector pushes external force, make the conducting terminal strain that is contained in the insulating body, push the corresponding electric conductor that is arranged on wafer module and the circuit board by the elastic force that the conducting terminal strain is produced, thereby realize conducting terminal and wafer module and the firm electric connection of circuit board.
The conducting terminal 7 of a kind of existing electric connector (not shown) as shown in Figure 6, this conducting terminal 7 is provided with a base portion 71, extends first elastic arm 72 and second elastic arm 73 of setting along 71 two ends of base portion respectively; Above-mentioned two elastic arms 72,73 also bend respectively in its end and are provided with first contact site 721 and second contact site 731.This conducting terminal 7 is contained in the corresponding terminal hole of electric connector (not shown), and its first contact site 721 and second contact site 731 are stretched on respectively outside the insulating body two relative surfaces (not shown).When electric connector and wafer module (not shown) and circuit board (not shown) when being connected, first elastic arm 72 and second elastic arm 73 are subjected to wafer module and circuit board institute's applied pressure respectively and strain take place, the elastic force that is produced makes first contact site 721 and second contact site 731 push the corresponding electric conductor that is arranged on wafer module and the circuit board respectively thus, thereby realizes conducting terminal 7 and wafer module and the firm electric connection of circuit board.
Yet this conducting terminal 7 can't realize in the design of high frequency electrical characteristic that bigger flexible adjustment is to adapt to the demand under the various different situations; And the base portion 71 of conducting terminal 7 is tabular setting, so the capacitance characteristic of conducting terminal is relatively poor.
In order to address the above problem, a kind of conducting terminal 8 of electric connector 6 first adjutage 82 that it comprises main body 81, fixedly install in main body one end bending, is separated from each other with main body and second adjutage 83 that can be slidingly matched with respect to main body 81 and respectively at first adjutage 82 and second adjutage, 83 terminal first contact site 821 and second contact sites 831 that are provided with as shown in Figure 7 and Figure 8.This main body is provided with sidewall 811, in the relative elastic arm 812 of sidewall 811 and main body 81; This second adjutage 83 extends in itself and second contact site, 831 opposing ends and is provided with the contact arm 832 that matches with elastic arm 812, and the cooperation by elastic arm 812 and contact arm 832 can be communicated with first adjutage 82 and second adjutage 83.
During use, by being applied one, electric connector 6 pushes external force, make conducting terminal 8 strains, as shown in Figure 8, the corresponding electric conductor (indicating) that the elastic force that is produced by conducting terminal 8 strains pushes first contact site 821 and second contact site 831 respectively to be arranged on wafer module 3 and the circuit board 4, thus realize the electric connection that conducting terminal 8 and wafer module 3 and circuit board 4 are firm.In engagement process, the sidewall 811 that the main body 81 of conducting terminal 8 is provided with can provide capacitance characteristic preferably; And, the elastic arm 812 that second adjutage 83 of conducting terminal 8 is provided with by contact arm that it was provided with 832 and main body 81 produces to be slidingly matched can realize the adjustable height of conducting terminal 8, thereby can reach bigger flexible adjustment in the design of high frequency electrical characteristic to adapt to the demand under the various different situations.
But, this conducting terminal 8 has following shortcoming at least: after wafer module 3 is electrically conducted by conducting terminal 8 and circuit board, electric current is from wafer module 3 corresponding electric conductors second contact site 83 of flowing through, contact arm 832, elastic arm 812, sidewall 811, first adjutage 82, first contact site, the 821 last circuit board 4 corresponding electric conductors that arrive, current path is longer, total electrical impedance is bigger, so it is more that conducting terminal 8 produces heat, thereby when the higher telecommunication signal of transmission frequency, owing to electrical impedance increases the performance that connects that the heat that produces can have a strong impact on electric connector 6 and wafer module 3 and circuit board 4.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector with conducting terminal of shorter electrical path.
The utility model provides a kind of electric connector that electrically connects wafer module and circuit board that is mainly used in, and it comprises insulating body, is contained in the plurality of conductive terminals in the insulating body.First adjutage that this conducting terminal comprises main body, extend to be provided with in main body one end, second adjutage that is provided with respect to first adjutage and respectively at first adjutage and terminal first contact site and second contact site that is provided with that extend of second adjutage; This first contact site and second contact site are provided with first elastic arm and second elastic arm in its end respectively, produce strain behind this first elastic arm and the second elastic arm pressurized and contacts the formation conductive path respectively with main body.During use, by being applied one, electric connector pushes external force, make the conducting terminal strain that is contained in the insulating body, the elastic force that is produced by the conducting terminal strain makes first contact site and the second contact portion don't push press the corresponding electric conductor that is arranged on wafer module and the circuit board, thereby realizes the electric connection of conducting terminal and wafer module and circuit board.
As further improvement of the utility model, this electric connector is provided with the both sidewalls that is oppositely arranged in the Subject Extension of conducting terminal, and this sidewall can provide capacitance characteristic preferably on the basis of shortening conductive path.
Compared with prior art, advantage of the present utility model is: this conducting terminal is provided with first elastic arm and second elastic arm in the end extension of its first contact site and second contact site.When conducting terminal matches with wafer module and circuit board, produce strain behind first elastic arm and the second elastic arm pressurized and contact the formation conductive path respectively with main body, shortened the conductive path of conducting terminal, reduce the heat that it produces when carry high frequency telecommunication signal, thereby realize good being electrically connected between electric connector and wafer module and circuit board.
