Background technology
The terminal 6 (electronic card coupler as shown in Figure 6) of general existing electric connector, after each terminal 6 is arranged on motherboard 7, each terminal 6 is the skewed of a predetermined angular, when Kato, electronic cards (as: SIM card or various memory card) is sent into after connector, can make each skewed terminal 6 contact conducting with the wafer in electronic cards.
But, because each terminal 6 is the skewed of a predetermined angular, and each terminal 6 is only the plate body of a reservation shape, on it, there is no any mechanism design, therefore, in the time of action that the empty calorie holder 8 in electric connector is wanted to exit, can be because of meeting terminal 6 reservation shape originally, this empty calorie holder 8 is produced has the situation that hooks terminal 6 (shown in the choosing of Fig. 7 circle) to occur, and then affect the action that empty calorie holder 8 exits (having to terminal 6 situation of blocking because hooking), now, if user still continues the application of force while extracting empty calorie holder 8, just can make terminal 6 because of excessive pullling cause distortion, so, cause the damage of electric connector, and significantly affect the electric connection effect of electric connector.
Utility model content
Main purpose of the present utility model is, avoid above-mentioned habit formula disappearance sustainable existence, the terminal that can be used as electric connector uses, and in the time that the empty calorie holder of electronic cards is exited, utilize intermediate board body, connecting portion and form coordinating of cephalic par appropriateness to bottom offset, pass through for empty calorie holder, avoid the useful life of terminal distortion, increase electric connector and have being preferably electrically connected effect and reach.
For reaching above-mentioned purpose, the utility model is a kind of terminal structure of electric connector, includes: a pedestal; Most being inclined upwardly respectively extended the edge contact terminal of being located at pedestal both sides, and the connecting portion and that each contact terminal includes respectively an intermediate board body, be located at respectively intermediate board body both sides is located at connecting portion one end and is resisted against the cephalic par on intermediate board body one end face; And most solder terminals from pedestal two ora terminalis to downward-extension that be located at respectively.
In an embodiment of the present utility model, this pedestal, each contact terminal and each solder terminal are one-body molded made.
In an embodiment of the present utility model, this pedestal outside is coated with an insulating barrier.
In an embodiment of the present utility model, one end of each intermediate board body proximity heads end is provided with a bending segment, and this cephalic par is resisted against on the lateral surface of this bending segment.
In an embodiment of the present utility model, on each connecting portion, be respectively equipped with the concave arc-shaped section of and opposite direction corresponding with bending segment.
The terminal structure of the utility model electric connector effectively improves habit formula disappearance really, the terminal that can be used as electric connector uses, and in the time that the empty calorie holder of electronic cards is exited, utilize intermediate board body, connecting portion and form coordinating of cephalic par appropriateness to bottom offset, pass through for empty calorie holder, avoid the useful life of terminal distortion, increase electric connector and have being preferably electrically connected effect and reach.

Embodiment
Refer to shown in Fig. 1, Fig. 2 and 3 figure, be respectively the side-looking view of three-dimensional appearance schematic diagram of the present utility model, perspective exploded view of the present utility model and the utility model contact terminal.As shown in the figure: the terminal structure of a kind of electric connector of the utility model, it is at least made up of a pedestal 1, most contact terminal 2 and most solder terminal 3, and wherein this pedestal 1, each contact terminal 2 and each solder terminal 3 are one-body molded made.
Above-mentioned carried pedestal 1 its outside is coated with an insulating barrier 11.
Each contact terminal 2 is inclined upwardly respectively and extends the both side edges of being located at pedestal 1, and each contact terminal 2 includes respectively an intermediate board body 21, the connecting portion 22 and of being located at respectively intermediate board body 21 both sides is located at connecting portion 22 one end and is resisted against the cephalic par 23 on intermediate board body 21 1 end faces, wherein one end of each intermediate board body 21 proximity heads ends 23 is provided with a bending segment 211, and this cephalic par 23 is resisted against on the lateral surface of this bending segment 211, and on each connecting portion 22, be respectively equipped with the concave arc-shaped section 221 of and opposite direction corresponding with bending segment 211.
Each solder terminal 3 is located at respectively two ora terminalis of pedestal 1 to downward-extension.
Refer to shown in Fig. 4 and 5 figure, be respectively the view of doing of use view of the present utility model and the utility model contact terminal.As shown in the figure: when the utility model is in the time using, can utilize the electrical combination of motherboard 4 of each solder terminal 3 and associated electronic device, use using the terminal as electric connector, and when associated electrical subcard (as: SIM card, or various memory card) empty calorie holder 5 want to exit action time, this empty calorie holder 5 can first touch the bending segment 211 of the set intermediate board body 21 of contact terminal 2, due to the bending segment 211 of these intermediate board body 21 one end with active state and cephalic par 23 mutually against, and the other end is fixing shape, therefore, in the time that empty calorie holder 5 touches this bending segment 211, this intermediate board body 21 just can be subject to the interlock of bending segment 211 and produce displacement downwards, until empty calorie holder 5 by after recycle its elasticity this intermediate board body 21 resetted, allow bending segment 211 abutment head ends 23, make this cephalic par 23 can be as the spacing use of the backstop of intermediate board body 21, so, can be in the time that empty calorie holder 5 be exited, utilize and coordinate with cephalic par 23 because of intermediate board body 21, connecting portion 22, and first contact with the bending segment 211 of intermediate board body 21, form appropriateness to bottom offset, to prevent that empty calorie holder 5 from having the situation of pullling contact terminal 2, except can effectively preventing that empty calorie holder 5 from causing while exiting contact terminal 2 distortion, more can increase the useful life of electric connector and contact terminal 2 is had to be preferably electrically connected effect.
