Abstract

The utility model discloses an electric connector assembly which is arranged on a circuit board so as to fixedly connect an electronic component. The electric connector assembly comprises an isolation body and a plurality of conductive terminals contained inside the isolation body; both ends of the conductive terminal respectively contact the electronic component and a circuit board in an elastic compression mode; the isolation body is further provided with a positioning structure so as to position the electric connector and fix the electric connector on the circuit board in advance. Compared with prior art, because the electric connector of the utility model does not need to use a metal upper shell and a metal lower shell and does not need to weld the electric connector on the circuit board, but the electric connector is provide with the positioning structure on the isolation body so as to position the electric connector and fix the electric connector on the circuit board in advance, the utility model can effectively avoid generating poor contact between a chip module consequently and the circuit board and can ensure the electrical conduction between the chip module and the circuit board.

Description

The electric connector combination

Technical field

The utility model relates to a kind of electric connector combination, especially a kind of electric connector combination that is used to connect LGA (land grid array, planar grid array) chip module.

Background technology

Occurred a kind of chip module of LGA type now on some electronic building brick (as computer), the conducting end of this chip module is a washer-shaped, and the electric connector that is attached thereto is provided with the terminal that contacts with the conducting end elastic compression.Fig. 1 and the common electric connector of industry that is shown in Figure 2, this electric connector 1 comprise mutual flexible connection metal upper casing 2 and metal lower shell 3, be contained in the metal lower shell 3 base 4 in order to carries chips module (not drawing among the figure), and be fixed in metal lower shell 3 one sides to fasten the rocking bar 5 of metal upper casing 2 and metal lower shell 3, this base comprises insulating body and is located in terminal in the insulating body, this terminal upper end contacts with chip module, and the lower end then is welded to connect with circuit board.But there is following defective in the electric connector of this structure: after the rocking bar closure, two diagonal positions on the metal lower shell can be subjected to the pulling force that rocking bar makes progress, thereby cause the buckling deformation that makes progress of two corners of metal lower shell, at this moment may push against the base respective edges in the side of metal lower shell corner, and base produced its power of upwards lifting, just can make the positions such as pad that are welded on the circuit board produce solder crack behind this power effect certain hour, cause loose contact between chip module and the circuit board.

Summary of the invention

The purpose of this utility model is to provide the combination of a kind of electric connector, and it can guarantee that excellent electrical property contacts between chip module and the circuit board.

For achieving the above object, the utility model electric connector, it is installed on the circuit board with fixedly connected electronic building brick, comprise insulating body and be located in plurality of conductive terminals in the insulating body, these conducting terminal two ends contact with electronic building brick and circuit board elastic compression respectively, and this insulating body further is provided with location structure, with electric connector location and predetermined fixed on circuit board.

Compared with prior art, because the combination of the utility model electric connector does not need to use metal upper casing and metal lower shell, also electric connector need not be welded on the circuit board, and tie up on the insulating body set position mechanism with electric connector location and predetermined fixed on circuit board, can not produce its power of upwards lifting base (insulating body), thereby can effectively avoid the phenomenon of loose contact between chip module and the circuit board to produce, guarantee electrically conducting between the two.

Embodiment

Below in conjunction with accompanying drawing the utility model electric connector is further detailed.

Extremely shown in Figure 7 as Fig. 3, this electric connector combination system comprises electric connector 10 and backboard 60, this electric connector 10 is to be installed on the computer circuit board 20, to connect the chip module 30 of LGA type, these chip module 30 tops are equiped with the radiator 40 to chip module 30 heat radiations, between radiator 40 and circuit board 20, be provided with support 50 to support radiator 40, be equiped with backboard 60 at the back side of circuit board 20 in addition, so that above-mentioned part is fixed together.

This electric connector 10 comprises insulating body 12 and some conducting terminals 14 that is located in wherein.This insulating body 12 extension downwards is provided with four reference columns 126, to insert in the hole 22 corresponding on the circuit board 20, plays the role of positioning.This conducting terminal 14 probably is＜shape, and it has elasticity, and two ends are respectively equipped with upper and lower contact jaw 142,144, with respectively with chip module 30 and circuit board 20 electrically contact mutually.

This backboard 60 is made by metal or plastic material, its four corners are provided with fixing hole 62, electric connector 10, chip module 30, support 50, radiator 40 are fixed together by bolt or other fixture, and backboard 60 can be reinforced circuit board 20, damages because of bending to avoid circuit board 20.This backboard 60 is provided with the through hole 64 of four corresponding above-mentioned reference columns 126 of difference, with as allowing bit architecture, avoids causing electric connector 10 correctly not to be installed on the circuit board 20 because of reference column 126 pushes up backboard 60.

Certainly, the bit architecture that allows of its backboard also is embodied as other multiple mode, as establishing pothole 72 (as shown in Figure 8) at backboard 70 middle positions, or on backboard 80, establish some ribs 82 (as shown in Figure 9), or on backboard 90, establish groove 92 (as shown in figure 10), or the like, cause electric connector correctly not to be installed on the circuit board to avoid locating capital to backboard.

Compared with prior art, because the combination of the utility model electric connector does not need to use metal upper casing and metal lower shell, also electric connector need not be welded on the circuit board, and be that electric connector terminal is pressed on the circuit board welding pad, thereby can effectively avoid the phenomenon of loose contact between chip module and the circuit board to produce, guarantee electrically conducting between the two.And allow bit architecture because on backboard, be provided with, can avoid locating capital and cause electric connector correctly not to be installed on the circuit board to backboard.
