Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used for testing a chip module on the circuit board that is installed on.

[background technology]

United States Patent (USP) bulletin has disclosed a kind of electric connector relevant with the utility model US7470149 number, and it accommodates some at least signal conductors, be used for exporting and input signal extremely and from the predetermining circuit assembling structure.

The defective of above-mentioned electric connector is: signal conductor is to adopt a kind of probe-type conducting terminal, the characteristics of such probe-type conducting terminal are to be typically provided with a metal sleeve, be provided with the first terminal, second terminal that can under spring action, move around in this metal sleeve, and the first terminal, second terminal are respectively equipped with the contact site that extends metal sleeve, and this contact site can shrink back and forth.Yet, along with electric connector miniaturization development trend, required distance between the adjacent conductive terminal is more and more littler, for example under the 0.5mm terminal pitch, can be as the resistance value that will guarantee electric connector above requiring, then the external diameter of metal sleeve need reduce thereupon, will make that machining is not easy, the cost costliness.

Therefore, necessaryly provide a kind of improved electric connector, to overcome the defective that the aforementioned electric connector exists.

[utility model content]

Technical problem to be solved in the utility model provides a kind of electric connector, and its signal conductor can adapt to electric connector miniaturization development trend.

For solving the problems of the technologies described above, the utility model provides a kind of electric connector, comprise pedestal and the some signal conductors made by electric conducting material, wherein pedestal is provided with first opening to hold signal conductor, signal conductor comprise the first terminal, second terminal and be placed in the first terminal and second terminal between spring, wherein the first terminal and second terminal all are sheet metal stamping parts.

Compare with correlation technique, electric connector of the present utility model has the following advantages: the first terminal of signal conductor and second terminal all are sheet metal stamping parts, its width is controlled easily, makes the easier demand that satisfies the terminal pitch miniaturization of design of whole electric connector.

[embodiment]

See also Fig. 1 to Fig. 2, electric connector 1 of the present utility model comprises pedestal 10 and is assembled in plurality of conductive terminals in the pedestal 10.Pedestal 10 is to be made by copper or similar electric conducting material, and it is provided with some first openings 100, second opening 102 and the 3rd opening 104.

Please refer to Fig. 3 and Fig. 4, conducting terminal comprises transmission signals respectively, power supply to signal conductor 12, the power conductor 14 of predetermining circuit and be used to provide the earthing conductor 16 of earthing potential to predetermining circuit, and wherein signal conductor 12 is identical with power conductor 14 structures.Each signal conductor 12 comprises the first terminal 120, second terminal 122 and is placed in the first terminal 120 and the spring 124 of 122 of second terminals, wherein the first terminal 120 and second terminal 122 all are sheet metal stamping parts, spring 124 is that elastomeric material is made, and is metal or nonmetal.

Signal conductor 12 and power conductor 14 are placed in respectively in first opening 100 and second opening 102, and the two is identical with assembling mode in second opening 102 in first opening 100.With the situation explanation of signal conductor 12 in first opening 100, signal conductor 12 is to be contained in first opening 100, and its periphery is provided with megohmite insulant 18, so that this signal conductor 12 and pedestal 10 electricity are isolated.Described megohmite insulant 18 comprises around the sleeve 180 of signal conductor 12 peripheries and the locating ring 182 that is fastened in first opening, 100 both sides respectively, the exposed surface of described two locating rings 182 is concordant with the both side surface of first opening 100 of pedestal 10 respectively, and the opening on two locating rings 182 only can pass through for the end that contacts of the first terminal 120 and second terminal 122.

The first terminal 120 of signal conductor 12 and second terminal 122 are combined in perpendicular mode, and 124 on described spring is placed in the first terminal 120 and second terminal, the 122 inner spaces that form and is connected to respectively on the first terminal 120 and second terminal 122.The situation of power conductor 14 in second opening 102 is identical with the situation of signal conductor 12 in first opening 100, repeats no more.

Please refer to Fig. 3, the structure of earthing conductor 16 is roughly similar with signal conductor 12, also comprise the first terminal 160 and second terminal 162 combined in perpendicular mode, and the first terminal 160 and second terminal 162 all are sheet metal stamping parts, difference is, the spring 164 of earthing conductor 16 be coated on the outside of the first terminal 160 and second terminal 162 and be connected to the first terminal 160 respectively and second terminal 162 on.

Earthing conductor 16 is to place the 3rd opening 104, and is different with power conductor 14 with signal conductor 12, and earthing conductor 16 is electrically to contact with pedestal 10.The 3rd opening 104 two ends are provided with step, and earthing conductor 16 is positioned electrically to contact in the 3rd opening 104 and with pedestal 10, and in the present embodiment, in the 3rd opening 104, between earthing conductor 16 and the pedestal 10 megohmite insulant are not set.Certainly, also can set up megohmite insulant, to make the usefulness of impedance adjustment.

To sum up, signal conductor 12 and power conductor 14 and do to be provided with megohmite insulant 18 between the copper material pedestal 10 of usefulness of ground connection, its thickness can be adjusted according to the dielectric coefficient of insulant, makes the easier demand that satisfies the terminal pitch miniaturization of design of whole electric connector 1.Equally, signal conductor 12 and power conductor 14 be because of being novel flat-plate shape metal stamping terminal, and the thickness that its width can the coordinated insulation thing is able to the elasticity adjustment, makes the easier demand that satisfies the terminal pitch miniaturization of design of whole electric connector 1.

In the utility model, the structure of signal conductor 12 and power conductor 14 and earthing conductor 16 is not limited to the foregoing description, and can exchange use between them.
