FIELD OF THE INVENTION

The present invention relates to an electrical connector assembly, and in particular, to an electrical connector assembly that prevents damage to a conducting terminal.

BACKGROUND OF THE INVENTION

At present, a land grid array (LGA) electrical connector is commonly used in the industry. The LGA electrical connector includes an insulation body, a conducting terminal disposed in the insulation body, a reinforcement piece disposed on a periphery of the insulation body, and a driving lever and a cover disposed at two opposite ends of the reinforcement piece. When a chip module is mounted, the cover and the driving lever need to be twisted and opened. Then the chip module is manually placed on the insulation body. At last, the cover and the driving lever are rotated and buckled, thereby implementing an electrical connection between the chip module and the conducting terminal in the insulation body. However, when the chip module is directly and manually mounted into the electrical connector, operation errors such as misaligning and using excessive strength may occur, which causes damage to the conducting terminal.

To solve the problem of causing damage to a conducting terminal, Chinese Patent No. CN201210314481.4 discloses an electrical connector assembly, including an insulation body 2, a conducting terminal 1 accommodated in the insulation body 2, and a guide plate 3 disposed on the insulation body 2. The guide plate 3 includes a guide frame 31 and a pulling plate 32 mounted on the guide frame 31. The guide frame 31 is provided with a frame body 310 abutting a side wall 20 of the insulation body 2. Slide tracks 313 are disposed on two opposite sides of the frame body 310. The pulling plate 32 includes a main body 320 and a pickup part 321. The main body 320 is inserted in the slide tracks 313, so that the pulling plate 32 is mounted on the guide frame 31 and covers the conducting terminal 1. When a chip module 4 is mounted into the electrical connector assembly, in a first step, the guide frame 31 and the pulling plate 32 of the guide plate 3 are assembled as a unity, and then the assembled guide plate 3 is mounted on the insulation body 2. In the second step, the chip module 4 is supported on the pulling plate 32. In the third step, the pickup part 321 is grasped with fingers, and then the pulling plate 32 is horizontally pulled out from a location between the guide frame 31 and the chip module 4. At this time, the chip module 4 falls freely. In the fourth step, the guide frame 31 is removed. The chip module 4 can be correctly mounted on the insulation body 2 by using the guide plate 3, thereby preventing operation errors occurred when the chip module 4 is directly and manually mounted. Further, the guide plate 3 is provided with the pulling plate 32, and the pulling plate 32 covers the conducting terminal 1, which can prevent exposure of the conducting terminal 1 before the chip module 4 is mounted on the insulation body 2. Therefore, the conducting terminal 1 can be kept free of pollution from dust, and accidental damage to the conducting terminal 1 can also be prevented.

However, because the pulling plate 32 is mounted on the guide frame 31, the guide frame 31 as an element needs to be added, which results in a complex structure and a high cost. Further, during mounting, it is required to assemble the pulling plate 32 with the guide frame 31 and then mount the guide frame 31 on the insulation body 2. The assembling and mounting process is complicated.

Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

As shown in FIG. 1 and FIG. 5, in a first embodiment of the present invention, an electrical connector assembly is used for electrically connecting a chip module 5. The electrical connector assembly includes an insulation body 1, multiple conducting terminals 3, and a separation plate 2.

As shown in FIGS. 1-5, the insulation body 1 is substantially rectangular, and has a conducting area 10. The conducting terminals 3 are fixed in the conducting area 10, and used for contacting the chip module 5. Two opposite first side walls 11 are formed by extending upward from two opposite sides of the conducting area 10. Two second side walls 12 are formed by extending upward from the other two opposite sides of the conducting area 10. Two positioning blocks 111 (which can reinforce strength of the insulation body 1) protrude upward at two opposite ends of the first side wall 11, and are used for positioning the separation plate 2. In certain embodiments, the positioning blocks 111 may not be disposed at two opposite ends of the first side wall 11. In other embodiments, there may be one or more positioning blocks 111. A support portion 14 is disposed between the two positioning blocks 111 on the first side wall 11, and is used for supporting the separation plate 2. A height of the support portion 14 is greater than that of the conducting terminals 3. A stop block 110 is formed by protruding from the positioning block 111 towards the conducting area 10. The stop block 10 is used for positioning the chip module 5. A positioning post 15 is formed by protruding on each of the second side walls 12 towards the conducting area 10. The positioning posts 15 are used for cooperating with a groove 50 on the chip module 5, so as to position the chip module 5 in the conducting area 10. The positioning posts 15 and the positioning blocks 111 are located on different sides of the conducting area 10, so that the separation plate 2 covers a large range above the conducting terminals 3. In other embodiments, the positioning posts 15 and the positioning blocks 111 may be located on a same side of the conducting area 10.

As shown in FIGS. 1-4, the separation plate 2 is an insulating film having a flat plate shape. The insulating film is a mylar sheet, so that the separation plate 2 has a simple structure and a low cost. The separation plate 2 has certain softness, so that the conducting terminals 3 are not damaged easily when contacting the separation plate 2. In other embodiments, the separation plate 2 may not be an insulating film, and the separation plate 2 may also be made of metal. The separation plate 2 includes a main body portion 20, which has a flat plate shape and covers the conducting terminals 3. An operating portion 21 horizontally extends from the main body portion 20. The main body portion 20 is clamped between the two positioning blocks 111, so that the main body portion 20 is positioned by the positioning blocks 111. The main body portion 20 is supported by the support portion 14, and a clearance exists between the main body portion 20 and the conducting terminals 3 in a height direction, so that the separation plate 2 does not contact the conducting terminals 3. In this way, when the separation plate 2 is pulled out, the separation plate 2 does not rub against the conducting terminals 3. In other embodiments, the separation plate 2 may also contact the conducting terminals 3, or the separation plate 2 is supported by the conducting terminals 3. The height of the main body portion 20 is less than the height of the positioning blocks 111, so that the positioning blocks 111 can also position the chip module 5 while positioning the separation plate 2, thereby preventing the chip module 5 from moving relative to the insulation body 1 along with the separation plate 2 when the separation plate 2 is pulled away from the insulation body 1. The operating portion 21 extends outward beyond the insulation body 1, and is used for horizontally pulling the separation plate 2 away from the insulation body 1. An end of the operating portion 21 bends upward, so that a user can more conveniently pull the separation plate 2 away from the insulation body 1.

As shown in FIGS. 1-6, when the chip module 5 is mounted into the electrical connector assembly, in a first step, the separation plate 2 is mounted on the insulation body 1. In this embodiment, the main body portion 20 is positioned by the positioning blocks 111, and the main body portion 20 is supported by the support portion 14. In a second step, the chip module 5 is mounted on the separation plate 2. The chip module 5 is positioned by using the positioning blocks 111, and the main body portion 20 of the separation plate 2 supports the chip module 5. In a third step, the operating portion 21 is pulled, so as to horizontally pull out the separation plate 2 from a location between the insulation body 1 and the chip module 5. Then the chip module 5 falls freely and contacts the conducting terminals 3 in the conducting area 10.

By using the separation plate 2 in this embodiment, when the chip module 5 is mounted downward into the insulation body 1, the chip module 5 is first located on the separation plate 2, and then the separation plate 2 is pulled out so that the chip module 5 falls freely, thereby preventing damage to the conducting terminals 3 caused by an operation error occurring when the chip module 5 is directly and manually mounted.

As shown in FIGS. 7-9, in a second embodiment of the present invention, differences between the second embodiment and the first embodiment lie in that: two separation plates 2′ are disposed, and are located symmetrically above the conducting area 10. The separation plate 2′ is provided with a main body portion 20′ clamped between the two positioning blocks 111. A concave portion 112 is formed between the two positioning blocks 111, and the height of the concave portion 112 is less than that of the conducting terminals 3. A clearance exists between the main body portion 20′ of the separation plate 2′ and the concave portion 112 in a height direction. That is, the clearance exists between the main body portion 20′ of the separation plate 2′ and the corresponding first side wall 11 in a height direction. An extension portion 22′, which extends from the main body portion 20′ and beyond the insulation body 1 and bends downward, is formed. An operating portion 21′ extends from the extension portion 22′, and is used for pulling the separation plate 2′ away from the insulation body 1. The operating portions 21′ of the two separation plates 2′ face different directions, so that the two separation plates 2′ are pulled away from the insulation body 1 from two directions. The electrical connector assembly further includes a stiffener 4. The stiffener 4 is substantially a rectangular frame body surrounding a periphery of the insulation body 1. The stiffener 4 has a support portion 14′ corresponding to each of the extension portions 22′ and glued to the extension portions 22′. The height of the support portions 14′ is less than the height of the first side wall 11. The support portions 14′ support the extension portions 22′. A clearance may also exist between the separation plate 2′ and the conducting terminals 3 in a height direction.

As shown in FIG. 10, differences between a third embodiment and the second embodiment lie in that: one separation plate 2″ is disposed, an operating portion 21″ extending beyond the insulation body 1 is disposed at each of two opposite ends of the separation plate 2′, and a pre-broken portion 23″ is disposed in the middle of the separation plate 2″. When the two operating portions 21″ are operated from two opposite directions, the separation plate 2″ is pulled apart at the pre-broken portion 23″ and is pulled away from the insulation body 1 from two opposite directions.

In summary, the electrical connector assembly in the present invention, among other things, has the following beneficial advantages.

(1) The separation plate 2 is positioned by the positioning blocks 111 of the insulation body 1. Therefore, no additional element needs to be added to position the separation plate 2, so that an electrical connector has a simple structure, a low cost, and is easy to be assembled.

(2) Compared with pulling out the separation plate 2 from only one direction, pulling the separation plate 2 away from the insulation body 1 from two directions can reduce a distance for which the separation plate 2 slides on the insulation body 1.

(3) The height of the separation plate 2 is less than the height of the positioning block 111, so that the positioning block 111 can position the chip module 5. In this way, when the separation plate 2 is pulled out from a location between the chip module 5 and the insulation body 1, the chip module 5 does not move relative to the insulation body 1. Besides, because the separation plate 2 is positioned by using the positioning blocks 111 for positioning the chip module 5, no additional structure needs to be disposed on the insulation body 1 to position the separation plate 2, thereby achieving effects of simple structure and low cost.
