Description

Electric connector

[technical field]

The utility model is about a kind of electric connector, relates in particular to a kind of chip module to be connected to electric connector on the printed circuit board (PCB).

[background technology]

Be used for connecting the electric connector of chip modules such as central processing unit and printed circuit board (PCB) in the prior art, but generally comprise insulating body, be located at the conducting terminal of the circuit in the conductive feet that is used for connecting chip module in the insulating body and the printed circuit board (PCB) and the pressing device that the chip for driving module contacts with conducting terminal, wherein pressing device is to be formed by the metal material punching press, be provided with terminal hole in the insulating body, in order to accommodate described conducting terminal.

The electric connector of described prior art shown in No. 92220952, TaiWan, China TW, has more corner around its pressing device, forms mutually discrete sidepiece, and the structure of these sidepieces is easier to distortion and positioning action deficiency.

Therefore, the electric connector of a kind of improvement of necessary proposition is to overcome the deficiencies in the prior art.

[utility model content]

Main purpose of the present utility model is to provide a kind of electric connector, and its gland has intensity preferably and stablizes the pressing force of chip module, and sound construction, and positioning action is better.

For reaching above-mentioned purpose, a kind of electric connector is used for chip module is connected to printed circuit board (PCB), and it comprises insulating body, and the structure that is square contains plurality of conductive terminals in it; Reinforcement members is installed on the insulating body bottom and is used for the supports insulative body; Gland, an end and reinforcement members articulate and cooperate, the sidewall that it comprises a central gap, is used to push the main board of chip module and is located in all sides of main board, this gland groove shape that roughly is square; Action bars is installed on reinforcement members one side, is used for the described gland of snap close.

Compared to prior art, electric connector of the present utility model has the gland of square groove shape, and this structure gland has stability and positioning action preferably.

[embodiment]

See also Figure 1 and Figure 2, the utility model electric connector 1 is used to electrically connect chip module (not icon) and printed circuit board (PCB) (not icon), and reinforcement members 20, the rotation that its insulating body 40, frame that mainly includes the structure that is square is located at insulating body 40 all sides is articulated in the gland 10 of reinforcement members 20 1 ends and is articulated in reinforcement members 20 other ends and gland 10 can be pressed on action bars 30 on the insulating body 40.Be provided with some accepting holes (not shown) that are used to hold conducting terminal (not shown) in the described insulating body 40.

Reinforcement members 20 is installed on insulating body 40 bottoms, make by metal material in the present embodiment, comprise a bottom (not label) and some sidepieces 21 that is located in insulating body 40 all sides, wherein a sidepiece 21 is provided with a snap close piece 201, this snap close piece 201 is used to lock described action bars 30 for outwards smoothly to be bent to form from described sidepiece 21.Be respectively equipped with first holding part 202 and second holding part 203 on the other two relative sidepieces 21.

Gland 10 is the square groove shape configuration of a hollow, for making by sheet metal, it is provided with a central gap 11 and is located in central gap main board 101 all around, be built into by interconnective sidewall 106 around the main board 101, to increase to being installed on the positioning action of the chip module on the insulating body 40, and approximate vertical between the two adjacent sidewalls 106 has stability preferably, is difficult for producing distortion.The directed portion 104 between the rotation section 103 is located in the rotation section 103 and that main board 101 1 ends extend to form a pair of cooperation reinforcement members 20, its relatively to the other end be provided with an auxiliary section 102 of pushing for action bars 30.This gland 10 is defined as the first surface 12 that is used for the crimping chip module and reaches and first surface 12 opposing second surface 13, first surface 12 is provided with a pair of boss 105, it is used to compress the chip module that is installed on the insulating body 40, further strengthening chip module and insulating body 40 interior the stable of conducting terminal contacts, this boss 105 has increased the intensity of main board 101 for protruding from first surface 12 simultaneously.In most preferred embodiment, this is located at the relative both sides of main board 101 respectively to boss 105, and is located on the same line, and is used for balance and puts on pressure on the chip module.

Action bars 30 comprises that a pair of rotation is crimped on the operating portion 302 that the rotating part (not label) of described first holding part, 202 downsides, the press section between a pair of rotating part 301 and are vertically connected at a rotating part end.Described press section 301 can be pressed on the auxiliary section 102 of gland 10 along with the rotation of operating portion 302, thereby clamps the fixing chip module.

Because the operation principle of action bars 30 is a known techniques, so be not described further at this.

The gland structure of existing electric connector, the utility model gland groove shape that is square, it has positioning action preferably, and sound construction.
