Description

Electric connector

[technical field]

The utility model relates to a kind of being used for the external connected electronic element is connected to electric connector on the circuit board.

[background technology]

Along with the continuous development of electronic technology, electronic product constantly develops towards light, thin direction, and the storage medium volume of electronic product constantly reduces, and the volume of connected electric connector also constantly reduces.

Present thin electric connector such as the described electric connector of Chinese 03279391.X patent, the interior plurality of terminals of passage that it comprises insulating body and is contained in insulating body, terminal comprises row's terminal and arranges terminal down, the electronic cards of butt joint is inserted from a side and is arranged between terminal up and down, contact with the contact sites of two row's terminals and realize electrically connecting, the contact site of arranging terminal down bends from bottom to top and extends to form, the direction of insertion of its bearing of trend and electronic cards is roughly the same, and the contact site of following row's terminal is arranged at the downside of electronic cards, so electronic cards is not easy to fracture when inserting, as shown in Figure 5, but the direction that the bending of the contact site 30 of last row's terminal is extended is opposite with the direction (direction shown in the B among the figure) that electronic cards is inserted, and the height height of contact point 300 on the aspect ratio contact site 30 of the peak A of the bending segment (the part label among the figure between two dotted lines is H) of the junction of contact site 30 and connecting portion 32 (being that connecting portion 32 is in the part at protuberance 34 upsides), when electronic cards is inserted, because the contact site of last row's terminal is in the upside of electronic cards, and contacting points position is lower on the contact site, when the insertion force of electronic cards is big slightly, last row's terminal is fractureed easily, and kneel the pin phenomenon, and then influence the normal use of electric connector.

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

[utility model content]

The purpose of this utility model is to provide a kind of electric connector that prevents to kneel pin and remain normal use.

In order to achieve the above object, the utility model electric connector, be used for the external connected electronic element is connected to circuit board, comprise insulating body and terminal, described insulating body is provided with terminal containing slot, terminal accommodating is in wherein, described terminal comprises the fixed part that is fixed in the insulating body, extend to form the weld part that is connected with circuit board by fixed part one end, and by fixed part other end bending extend to form with the external connected electronic element on the contact site of side contacts, contact site is provided with and the contacted contact point of external connected electronic element, and the height of described contact point position is higher than the height of contact site and fixed part junction bending segment peak.

The height of the contact point position on the contact site of the utility model electric connector terminal is higher than the height of contact site and fixed part junction bending segment peak, can prevent when the outward element insertion force is big slightly that the contact site of terminal fractures and kneels the pin phenomenon, avoid the existing problem of background technology, can make electric connector remain normal use.

[embodiment]

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

Please refer to Fig. 1 to shown in Figure 3, the utility model electric connector 1 is used for external connected electronic element (as electronic cards 2 (Fig. 2 shows the partial schematic diagram of electronic cards) etc.) is connected to circuit board (not shown), this electric connector comprises insulating body 10 and the shell 13 that cooperates with insulating body 10, be provided with terminal at

insulating body

10 and 13 on shell, terminal comprises the first terminal 11 (terminal that promptly is installed in upside is the row's of deserving to be called terminal also) and second terminal 12 (terminal that promptly is installed in downside also claims row's terminal down).

As Fig. 2, Fig. 3, shown in Figure 4, insulating body 10 both sides are respectively equipped with first, second terminal containing slot 101,102, the first terminal 11 is contained in the first terminal accepting groove 101 of insulating body one side, second terminal 12 is contained in second terminal containing slot 102 of insulating body opposite side, and shell 13 matches with insulating body 10 and first,

second terminal

11,12 is fixed on 13 on insulating body 10 and shell.The first terminal 11 comprises first fixed part 110, extend to form first weld part 111 by the outwards vertical bending of first fixed part, 110 1 ends, first weld part 111 can be welded on the circuit board, by first fixed part, 110 other ends bendings and be tilted to and extend to form first contact site 112, first contact site 112 forms and electronic cards 2 contacted contact points 1121 near the free end end is outstanding downwards, and the height of contact point 1121 positions is higher than the height of bending segment (the part label among the figure between two dotted lines is 114) peak 115 of first contact site 112 and first fixed part, 110 junctions.Second terminal 12 comprises second fixed part 120, extend to form second weld part 121 by the outwards vertical bending of second fixed part, 120 1 ends, second weld part 121 can be welded on the circuit board, after vertically bending towards invagination and extend by second fixed part, 120 other ends more upwards inflection extend to form second contact site 122.First, second fixed part 110,120 is clamped to 13 on the terminal containing slot of insulating body 10 and shell respectively, the common formation in insulating body 10 and shell 13 assembling backs docked electronic cards 2 docking ports 100, and electronic cards 2 is plugged on and matches jointly with first, second terminal in the docking port and be connected on the circuit board.

First contact site, 112 bearing of trends that the utility model is electrically connected the first terminal 11 are opposite with the direction of insertion of electronic cards 2, and the height of contact point 1121 positions is higher than the height of bending segment 114 peaks 115 of first contact site 112 and first fixed part, 110 junctions.When electronic cards 2 is inserted in the electric connector, electronic cards 2 is arranged at contact site 112 downsides, first contact site 112 of the first terminal has the trend of upwards upspringing or is subjected to an active force that is tilted to, can prevent when the external connected electronic card insertion force is big slightly that first contact site of the first terminal fractures and kneels the pin phenomenon, avoid the existing problem of background technology, can make electric connector remain normal use.
