Referring to the first to fifteenth figures, the present invention provides an electrical connector assembly 100 for electrically connecting an electrical module 600 and an optical jumper 700 to a printed circuit board . The electrical module 600 has a locking post and an ejecting part. The electrical connector assembly 100 includes a metal bracket 102 that surrounds the insulating body 104. The metal bracket is mounted with a movable holding rod 122 and a locking member 150. The locking member 150 has a locking state for fixing the electrical module 600 and a power supply gas model Block 600 exits the unlocked state. A plurality of terminals 106 are installed in the rear area of the insulating body 104 to form a fixed connector 108. The insulating body 104 is disposed in the metal support 102. The electrical module 600 is installed into the metal bracket 102 to form an electrical connection with the conductive terminal 106 of the insulating body 104. The front area of the insulating body 104 receives the optical jumper 700. The optical jumper 700 is assembled downward to the front area of the insulating body 104 in the vertical direction, and the optical jumper 700 is separated from the electrical module 600 from front to back.

The electrical module 600 includes a frame 110 to receive electronic components. The conductive terminals 106 of the electrical connector 112 are connected to the conductive terminals 106 of the fixed connector 108 by solder balls. A cover 116 is attached to the frame 110 to cover the electronic components. The electrical module 600 has a locking post and an ejecting part. The frame 110 includes a pair of first pillars 118 extending laterally to lock the locking member 150. A plurality of second columns 120 extending downward are received in corresponding receiving holes 702 of the optical jumper 700. The electrical connector 112 forms a pair of outer protrusions 115 for use with the locking member 150.

The metal bracket 102 is installed with a retaining rod 122 and a locking member 150. The metal bracket 102 is soldered on the printed circuit board 500. The metal bracket 102 is provided with a locking block 124 at the other end opposite to the locking member 150. The holding rod 122 may be locked by the locking block 124, and after being pressed, the holding rod 122 may be released from the locking block 124 to release the locking. The metal bracket 102 is further provided with a pair of guiding blocks 126 to guide downward and press the electrical module 600 into the insulating body 104. The metal bracket 102 is provided with a main groove 128. The holding rod 122 forms a pivot 130 received in the main slot 128. A pair of operating arms 132 moves between an upper position and a lower position on the lower side of the locking block 124. The upper position is between the locking block 124 and the guiding block 126. The locking block 124 and the exit lever 152 form a U-shaped structure. The eject lever 152 is used to provide a pivot 154 of the locking member 150 to allow the locking member 150 to be pivotally mounted on the metal bracket 102. The pivot 154 extends through the first pivot hole 156 of the locking member 150 and the second pivot hole 158 of the metal bracket 102. When the locking member 150 is not locked and rotates downward, the locking member 150 further includes a pair of exit blocks 160 to exit upward from the outer protrusion 115. When the holding rod 122 is in the lower locking position, the pair of restricting blocks 162 is pressed downward by the corresponding operating arm 132, and in the lower locking position, the operating arm 132 is locked to the locking block 124 Below. A pair of contact blocks 164 are used to hold the eject lever 152 in a corresponding position. A pair of slots 166 are formed in the latch 150 to receive the pivot 130, thereby allowing the latch 150 to move downward relative to the pivot 130. The buckle 150 has a buckle head 168 that presses down on the buckle column and an exit block 160 that presses up against the exit portion. When the lock When the member 150 is in the locking state, a pair of locking heads 168 press down the first cylinder 118 accordingly. The locking block 124 is provided with a restricting block 162 below the locking head 168, and the restricting block 162 upwardly supports the holding rod 122.

When the locking member 150 is in the locked state, the holding rod 122 fixes the locking member 150 to prevent the locking member 150 from being unlocked improperly; when the locking member 150 is in the unlocked position, the holding lever 122 releases the alignment Only when the locking member 150 is fixed, can the electrical module 600 withdraw from the metal bracket 102. When the holding lever 122 is locked by the locking block 124, the restricting block 162 is pressed downward by the operating arm 132, a downward force is applied to the ejecting lever 152, and the ejecting lever 152 Press down the contact block 164 to have a tendency to rotate, so that the locking member 150 is rotated and discharged. When the holding rod 122 is released from the locking block 124 and held in a position between the locking block 124 and the guide block 126, the restricting block 162 is no longer directed by the operating arm 132 Press down to allow the latch 150 to rotate. When a downward force is applied to the exit lever 152, the exit lever 152 presses down the contact block to obtain a rotation tendency. Once rotated, the locking head 168 no longer locks the corresponding first cylinder 118, and the ejection block 160 pushes the corresponding outer protrusion 115 upward to push the electrical connector 112 away from the fixed connector 108 to The entire electrical module 600 is allowed to move upward. In this embodiment, the eject lever 152 is pressed down by the flange 170 of the locking member 150, and the eject lever 152 is held to the locking member 150 by three holding points. The exit lever 152 is in contact with the flange 170, and the pivot 154 is received in the second pivot hole 158.

Unless the holding rod 122 is intentionally released from the locking block 124, the holding rod 122 ensures a reliable locking between the locking member 150 and the corresponding electrical module 600. On the other hand, the electrical module 600 is advantageously maintained in a predetermined manner by the locking head 168 and the first cylinder 118. Due to the contact between the operating arm 132 and the restriction block 162, the holding rod 122 is in a tensioned manner to drive the electrical module 600 to move downward.

In summary, the present invention has indeed met the requirements of the invention patent, and the patent application has been filed in accordance with the law.
