Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector for carrying a chip module and electrically connected to the circuit board.

In circuits consisting of several active and passive components, electronic packages, such as wafer modules, are miniaturized electronic components. To ensure their safety and reliability during use, almost all wafer modules must be tested before installation. Long-term high-temperature operation of the wafer module can invalidate the defective wafer module as soon as possible, thereby screening out the defective wafer module, and the tested wafer module is soldered or assembled to the electronic terminal product. It can be used safely without premature failure. The electrical connector is used to house the wafer module and electrically connect it to the test board for high temperature operation testing.

However, the electrical connector of this structure has a defect: when the temperature of the wafer module is too high, the terminal block will be arched downward, causing damage to the electrical connector.

Therefore, it is necessary to provide an improved electrical connector to overcome the deficiencies of the related art.

The technical problem to be solved by this creation is to provide an electrical connector that prevents the terminal block from arching due to the high temperature of the wafer module.

The present invention provides an electrical connector for carrying a chip module and electrically connected to a circuit board, comprising an insulating body and a conductive terminal provided with a base body and a terminal block, the upper surface of the base body being provided for carrying And the bearing space of the fixed chip module, the terminal block is assembled in the body, the conductive terminal penetrates the terminal block and is exposed in the bearing space, the electrical connector further comprises an elastic member and a positioning screw, the positioning screw fixes the terminal block to the seat body and The seat body is spaced apart by a certain distance, and the elastic member abuts against the top seat. When the terminal block is subjected to downward pressure, the elastic member causes the terminal block to have a tendency to be away from the seat body.

Compared with the prior art, the present invention has the following advantages: the elastic member and the positioning screw of the present invention can maintain a certain elastic distance between the terminal block and the base body, and prevent the terminal block from being overheated. Arching phenomenon.

Referring to the first and second figures, the present electrical connector 100 is used to carry the wafer module 200 and is electrically connected to a circuit board (not shown), which includes a base 11 and a terminal block 12. The insulating body 1, the plurality of elastic members 3 for fixing the terminal block 12 to the seat body 11 and the set screws 4, which will be described in detail below.

The insulating body 1 is substantially a rectangular frame structure. The upper surface of the base body 11 is provided with a bearing space 111 for carrying the wafer module 200. The wafer module 200 can be fixed in the bearing space 111, and the lower surface of the base body 11 is provided. There is a receiving space 112 for receiving the terminal block 12, and the fourth figure is clearly shown. The first rotating shaft 113 and the second rotating shaft 114 are respectively disposed on opposite sides of the seat body 11, and the first rotating shaft 113 is parallel to the second rotating shaft 114.

The present invention further includes a first cover 51 pivotally connected to one end of the insulative housing 1 and a second cover 52 pivotally connected to the first cover 51. The first cover 51 is rotatable relative to the base 11 about the first rotating shaft 113, and the second cover 52 is rotatable relative to the first cover 51 about the second rotating shaft 114. The electrical connector 100 further includes a latching portion 6 . The latching portion 6 is provided with two latching hooks 61 . The lower surface of the latching body 11 is correspondingly provided with a recess 116 for engaging with the latching hook 61 of the latching portion. The fourth picture is clearly shown. After the wafer module 200 is placed in the bearing space 111, the first cover 51 is rotated to fix the wafer module, and then the second cover 52 is rotated, so that the first cover 51, the second cover 52 and the base 11 are horizontal. The direction is parallel, and finally the locking portion 6 is pressed, so that the hook 61 of the locking portion 6 is fastened to the recess 116, so that the wafer module 200 can be firmly fixed in the bearing space 111.

Referring to the third to fifth figures, the terminal block 12 has a rectangular shape, and a circular hole 13 is formed in four diagonal corners of the rectangle. The elastic member 3 and the positioning screw 4 respectively pass through the circular hole 13 to fix the positioning terminal block. 12 to the seat 11. The terminal block 12 includes an upper plate 121 and a lower plate 122, and the upper and lower plates are fixed by a plurality of screws 14. The electrical connector 100 further includes a conductive terminal 2 that extends through the terminal block 12 and is exposed to the bearing space 111 of the base for connection with the wafer module 200. The elastic member 3 is a coil spring. After the two plates are fixed together, the elastic member 3 is received in the circular hole 13. The positioning screws 4 are respectively locked to the seat body through the circular hole 13 and the elastic member 3. In the preferred embodiment, the positioning screws 4 are located only on a pair of diagonal sides, and the other pair of diagonal holes 13 A spring is disposed, and the base 11 integrally extends out of a pair of protrusions 117. The pair of protrusions 117 are inserted into the spring of the circular hole 13 for positioning the terminal block 12. The positioning screw 4 can fix the terminal block to the base 11 The accommodating space 112 is spaced apart from the seat body 11 by a certain distance. The sixth to eighth figures clearly show that the elastic member abuts the tip sub-seat 12, and the elastic member makes the terminal block 12 when the terminal block 12 is subjected to downward pressure. With the tendency to be away from the direction of the seat body 11, the elastic member 3 and the set screw 4 can maintain the distance between the terminal block 12 and the seat body 11 to prevent the terminal block from arching due to excessive temperature of the wafer module. The electrical connector 100 further includes a heat dissipating device 7 that is fixed to the cover by screws 71 to prevent damage to the wafer module caused by high temperature.

The elastic member and the positioning screw of the electrical connector of the utility model can maintain a certain elastic distance between the terminal block and the base body, thereby preventing the terminal block from arching caused by overheating of the wafer module and avoiding damage.

In summary, this creation is in line with the new patent requirements, and the patent application is filed according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the foregoing embodiments, and any equivalent modification or change made by a person familiar with the skill of the present invention in accordance with the spirit of the present invention is It should be covered by the following patent application.
