Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially a kind of electric connector that can be used for the detection chip module performance.

[technical background]

In use safe and reliable for guaranteeing miniaturized electric sub-components such as chip module, nearly all chip module all must be tested before installation.This test is put into electric connector with chip module and is carried out long high temperature running, can make and exist the chip module of defective to lose efficacy as early as possible, thereby imperfect chip module screened eliminate, and just can use safely after being assembled to electronic terminal product by the chip module of test, can not lose efficacy as early as possible.

Consult Chinese utility model patent and announce 201000930Y, 201018168Y patent, all disclosed a kind of electric connector relevant with the utility model, this electric connector roughly is made up of three parts, is respectively pedestal, lid and conducting terminal.Pedestal is typically provided with a host cavity of accommodating chip module, and this host cavity is the through hole that connects a bit, by being provided with base plate in base bottom, accommodates or the terminal containing slot of fixing conducting terminal and be provided with on base plate; The host cavity of some pedestal is the groove of non-perforation, directly is provided with terminal containing slot in the host cavity bottom, and may also be provided with the base plate of fixed conductive terminals in base bottom.Lid generally is articulated in pedestal one end, is used for to pressing down chip module, and chip module and conducting terminal are electrically connected.

Yet the chip module of above-mentioned electric connector is directly to press on the terminal containing slot, if chip module is pressed excessively, may cause the damage of chip module or conducting terminal.Specifically,, then may make conducting terminal insertion tin ball dark excessively when chip module is provided with the tin ball, thus the damage chip module; When chip module and conducting terminal are to electrically connect in the face contact mode, then may make conducting terminal excessively be pushed and damage.

Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.

[utility model content]

The technical problem that the utility model solved provides a kind of electric connector that can the positioning chip module prevent chip module or conducting terminal damage.

For solving the problems of the technologies described above, the utility model provides a kind of electric connector, and it comprises the pedestal that is provided with terminal accommodation holes, somely is contained in the conducting terminal in the terminal accommodation holes and is connected with pedestal and can be with respect to the lid of pedestal Unscrew or closure.Wherein, a terminal accommodation holes side relative with lid is provided with some strutting pieces protruding upward, and is provided with the guiding face with guidance function to small part strutting piece upper end.

Compared with prior art, the utlity model has following advantage: owing to be provided with strutting piece around the terminal accommodation holes, when chip module when pressing down, can locate by strutting piece, thereby decrement that can the management and control conducting terminal, avoid conducting terminal to be damaged, can avoid chip module excessively to push and stabbed simultaneously by conducting terminal by excessive compression.The utility model also is provided with the guiding face with guidance function on the part strutting piece, can guide chip module and make it be easy to the location.

[embodiment]

See also 1 figure to shown in Figure 5, the utility model is a kind of electric connector, in order to reach the electric connection between chip module 7 and the circuit board (not icon), it comprises pedestal 2, is contained in the plurality of conductive terminals 5 in the pedestal 2 and is connected the also lid 4 of rotatable closure or openness with pedestal 2.

Pedestal 2 is roughly rectangular, and it comprises panel-shaped base body 21 and is positioned at the base plate 23 of matrix 21 bottoms.Matrix 21 middle parts cave inward and are provided with host cavity 22.This host cavity 22 is the groove of non-perforation, terminal accommodating districts 220 that it is further divided into and chip module 7 size is roughly the same and the pick-up area 221 of being located at terminal accommodating district 220 four sides and being connected, this pick-up area 221 with terminal accommodating district 220 be used for making things convenient for the user by tool or the chip modules 7 that manually will be placed in the terminal accommodating district 220 take out.Terminal accommodating district 220 is provided with the terminal accommodation holes 2201 of accommodating conducting terminal 5, around terminal accommodation holes 2201, be provided with some strutting pieces 222, this strutting piece 222 is located at the local area in terminal accommodation holes 2201 zones, and it mainly is located at the outer rim in terminal accommodating district 220 and the mid portion in terminal accommodating district 220.Strutting piece 222 is divided into two kinds, a kind of cylinder that is, be located at the outer rim in terminal accommodating district 220, another kind of strutting piece 222 is located at four zones between the terminals of adjacent accepting hole 2201, and have four corresponding with each terminal accommodation holes 2201 respectively surfaces, be provided with oblique guiding face 2220 between the upper surface of this surface and strutting piece 222, with guiding chip module 7.Base plate 23 is provided with the hole (not label) relative with terminal accommodation holes 2201 with fixed conductive terminals 5.

Lid 4 comprises by rotating shaft and is articulated in first lid 41 of pedestal 2 one ends and second lid 42 that links to each other by rotating shaft with first lid, 41 other ends.The free end of second lid 42 is provided with buckle 43, and this buckle 43 can be held in lid 4 with pedestal 2 buttons, to form the electric connection between chip module 7 and the conducting terminal 5.Second lid 42 is provided with heat abstractor 6, and after electric connector fitted together, the end face butt of heat abstractor 6 and chip module 7 was beneficial to the heat radiation of chip module 7.
