Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that electrically connects between circuit board and the chip module of reaching especially.

[background technology]

Electric connector is widely used in the various electronic equipments, is used for the electronic component two separation, as providing the path that electrically conducts between chip module and the printed circuit board (PCB).

Along with science and technology development, electric connector develops towards the direction of miniaturization, densification and diversification, the size of electric connector is also more and more littler, thereby cause interior other size of component of electric connector also to diminish thereupon, insulating body for example, will accommodate the more conducting terminal of number in limited insulating body, even the quantity of accommodating conducting terminal in the terminal accommodating district increases, the spacing between the conducting terminal is dwindled.When chip module moves downward when being in contact with one another with conducting terminal because of stressed, may be because of other factors such as the spacing between the stressed excessive and conducting terminal is less, and cause the end and the adjacent conductive termination contact of conducting terminal, phenomenon is short-circuited, even the damage chip module, thereby influence electric connection between electric connector and the chip module.

Therefore, necessary existing electric connector is improved to overcome the aforementioned disadvantages of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector that can effectively avoid short circuit phenomenon to take place.

The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, can electrically connect chip module and printed circuit board (PCB), it comprises: insulating body and conducting terminal, insulating body is provided with the terminal accommodating district of accommodating conducting terminal, conducting terminal comprises that holding parts and the autonomous body that extend at the two ends of main part, autonomous body bend the contact site that extends, the end of contact site is attached with insulating material, can prevent to be short-circuited because of contact adjacent conductive terminal.

Compared to prior art, the utility model electric connector has following beneficial effect: the conducting terminal end of the utility model electric connector is by adhering to insulating material, in the time of can avoiding pressurized and adjacent conductive termination contact and the phenomenon that is short-circuited.

[embodiment]

The utility model is a kind of electric connector that electrically connects chip module (not shown) to printed circuit board (PCB) (not shown), and this electric connector comprises conducting terminal 1 and accommodates the insulating body 2 of conducting terminal 1.

Consult shown in Figure 1, insulating body 2 is one-body molded by plastic material, roughly rectangular structure, it comprises base portion 20, is positioned at the protuberance 22 that place, base portion 20 centre positions is used to accommodate the terminal accommodating district 21 of conducting terminal 1 and is positioned at 20 4 bights of base portion and upwards protrudes out.

Consult Fig. 2 and shown in Figure 4, conducting terminal 1 is by the moulding of metal material integrated punching, it opposite end that comprises the main part 10 that roughly is plate-like structure, autonomous body 10 upwards reaches the holding parts 11 that extends simultaneously downwards, the bottom of holding parts 11 be provided with towards each other away from the hangnail 12 that protrudes out of direction, the lateral margin of holding parts 11 is provided with the depressed part 13 that caves inward above hangnail 12, described depressed part 13 scrapes in the time of not only can accommodating and go into terminal accommodating district 21 because of 12 groups of hangnails bits and the elastic force of inside retraction is provided can also for hangnail 12.The middle part that conducting terminal 1 also is included in main part 10 apical margins earlier backward bending then protrude out roughly the kink 14 that is " U " type structure forward, the end of being located at kink 14 slightly be behind the horizontal-extending again the upwards terminal contact site 16 of bending downwards of the elastic portion 15 of bending and own elasticity portion 15.Wherein, the utility model most preferred embodiment is by attaching or coated mode is attached to the end of contact site 16, to prevent conducting terminal 1 contact adjacent conductive terminal 1 phenomenon that is short-circuited with insulating material 17.Certainly also insulating material 17 can be attached to other zone that conducting terminal 1 may contact with adjacent conductive terminal 1 behind compressive deformation, for example shown in Figure 3, the bottom surface of elastic portion 15.Insulating material 17 can be that acrylic glue or other have the material of better insulation effect.

Please specifically consult Fig. 3 and shown in Figure 4, conducting terminal 1 arrangement is assembled in the terminal accommodating district 21 of insulating body 2, after chip module 3 is applied downward pressure, the contact site 16 of conducting terminal 1 moves downward because of driving elastic portion 15 behind the pressurized, but because the spacing between the conducting terminal 1 is less, the contact site 16 of conducting terminal 1 is in contact with one another easily with the upper surface of the elastic portion 15 of adjacent conductive terminal 1, even and the end of the contact site 16 of the utility model conducting terminal 1 is attached with the insulating material 17 contacts phenomenon that also can not be short-circuited.Equally, elastic portion 15 surfaces of conducting terminal 1 also can be attached with insulating material 17, when chip module 3 applied pressures are bigger, back and other zone of adjacent conductive terminal 1 phenomenon that also can not be short-circuited when contact even elastic portion 15 deforms makes spacing between the conducting terminal 1 than hour still having enough margins of safety.
