[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electronic card coupler that is used to realize chip module and circuit board electric connection especially.

[background technology]

At present, electric connector is widely used in individual calculator and other electronic equipment, its group is located on the circuit board, and can peg graft for all kinds of chip modules, electrically conduct so that reach between chip module and circuit board, existing this kind electric connector can be consulted United States Patent (USP) and announce the 5830017th and China Patent No. ZL97120003, these electric connectors all have the insulating body of a longitudinal, central authorities at its insulating body are provided with slot, chip module for specific standard is pegged graft, the two side of the insulating body of slot both sides is provided with the plurality of terminals accepting groove, plurality of conductive terminals is contained in wherein, during application, the inserted terminal of chip module is housed in the slot of this electric connector, reaches with engaging of chip module current-carrying part by conducting terminal to electrically conduct between chip module and electric connector.

But, fast development along with electron trade, information transfer rate requires more and more higher, be mapped to the electric connector industry, show under the prerequisite with volume that concentrate increasing conducting terminal on the plastic cement main body, the thing followed is to cause that spacing is more and more littler between terminal, terminal intensity more and more a little less than, simultaneously production cost also can be more and more higher.

Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[utility model content]

Thereby the purpose of this utility model is to provide the electric connector that a kind of structural design is simple, can effectively strengthen terminal intensity and the low manufacturing cost of saving material.

For reaching above-mentioned purpose, the technical scheme of the utility model electric connector is achieved in that a kind of electric connector, be suitable for electrically connecting with subcard, it comprises insulating body and plurality of conductive terminals, wherein insulating body comprises that the central slot that can accommodate subcard reaches the passage of accommodating that communicates with central slot, described conducting terminal is contained in accommodating in the passage in the insulating body, and each conducting terminal have with central slot in accommodate the contacted contact site of subcard, it is characterized in that: insulating body is provided with some elasticity posts that can produce strain with termination contact portion jointly, this elasticity post is provided with at least one elastic contact part, describedly accommodate the centre that passage is positioned at described elasticity post, described conducting terminal is an arc elastomer, its contact site slightly is wider than the stop section, described insulating body extension downwards is provided with reference column, and a tubbiness cylinder is placed on the reference column.

Compared with prior art, the utility model electric connector, its project organization is simple, saves material, and can effectively strengthen terminal intensity, and cost is lower, is convenient to a large amount of productions, has improved production efficiency.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

Please refer to Fig. 1 to shown in Figure 2, the utility model electric connector is used to be installed in circuit board (not icon), can supply chip module (icon is not equivalent to subcard) to insert, comprise the insulating body 1 that is longitudinal and be housed in plurality of conductive terminals 2 in the insulating body.

Please refer to illustrated in figures 1 and 2, insulating body 1 is cut apart hurdle 11 and is divided into two parts, this cuts apart the effect that hurdle 11 can play the positioning chip module, be provided with central slot 12 in the insulating body 1, insertion for chip module, and plurality of elastic post 13 (please referring to diagram 5), this elasticity post 13 is provided with accommodates passage 131, accommodating passage 131 communicates with central slot 12, and be positioned at the centre of described elasticity post 13, plurality of conductive terminals 2 is contained in accommodates in the passage 131, this side of accommodating passage 131 is all given prominence to and is provided with a pair of clamping part 130 is elastic contact part, this clamping part 130 is generally designed to an arc, when chip module is inserted into central slot 12 with vertical direction after, the contact site 22 of chip module and terminal 2 is inconsistent, thereby produce the elasticity extruding force, the contact site 22 that makes terminal 2 moves along the normal orientation of the clamping part 130 of insulating body 1, thereby produce the forward contact force by press nip 130, this moment, the contact site 22 of terminal produced strain with elasticity post 13 with common and chip module, because elasticity post 13 has the effect of assistant spring, so can effectively strengthen the intensity of terminal 2.The lower ends downward extension of described insulating body 1 also is provided with two reference columns 14, one tubbiness cylinder 15 is placed on the described reference column 14, be plugged on the circuit board jointly, to realize being connected of this electric connector and circuit board, the material of tubbiness cylinder 15 is different with the material of this insulating body 1, this kind reference column is made as the structure of separate type, and the material of tubbiness cylinder 15 has heat-resisting quantity preferably, thereby during welding, can adapt to the requirement of high temperature, design is convenient to save more expensive exotic material like this, thereby can reduce production cost.

Please refer to Fig. 3 to shown in Figure 5, terminal 2 is an arc elastomer, and its stop section 21 is accommodated and supported to terminate in and accommodate in the passage 131, is provided with a contact site 22 by stop section 21 bending downwards, this stop section 21 is supported to terminate in and is accommodated in the passage 131, contact site 22 is played the effect of normal direction location; This contact site 22 faces a pair of clamping part 130 on the described elasticity post 13, is to insert the connecting portion 24 of accommodating in the passage 131 by this contact site 22 in bending downwards, being in terminal Plug Division 25 can be plugged on the corresponding circuit board, the contact site 22 of wherein said terminal 2 slightly is wider than stop section 21, thereby being contained in, stop section 21 accommodates in the passage 131, contact site 22 can produce strain with clamping part 130 interferences when normal direction is moved, jointly chip module is produced clamping action.Terminal 2 for satisfy with circuit board on the hole site cooperate requirement, its Plug Division 25 can be designed to straight formula and two kinds of profiles of folding type (as Fig. 4), avoids interference so that peg graft.

During assembling, earlier terminal 2 upwards is inserted into accommodating in the passage 131 insulating body 1 from the lower end of insulating body 1, be inserted on the corresponding circuit board in Plug Division 25 terminal 2, at this moment, chip module is an anchor point to cut apart hurdle 11, after being inserted in the central slot 12 of corresponding insulating body 1, terminal 2 can constitute elastic parts jointly with elasticity post 13, so can effectively strengthen the intensity of terminal 2, and chip module provides the contact pressure of forward, contact with the normal of chip module with assurance terminal 2, thus the conducting of realization circuit.
