Because the guiding holes 131 of the pressing cover 1 are limited to move in the front-rear direction D1 and the left-right direction D3 by the two supporting rods 3, the guiding holes 131 of the pressing cover 1 basically only can move in the up-down direction D2 relative to the two supporting rods 3, that is, the pressing cover 1 only can move in the up-down direction D2 relative to the two movable plates 2. Movement of the two movable plates 2 in the up-down direction D2 and the front-rear direction D1 is limited by the two supporting rods 3, basically, the two movable plates 2 only can move laterally along the two supporting rods 3 (along the left-right direction D3), that is to say, the two movable plates 2 only can move inwardly or move outwardly relative to the pressing cover 1 along the left-right direction D3.

With the two supporting rods 3, the pressing cover 1 is assembled with the connecting portions 21 of the two movable plates 2 in a manner that the pressing cover 1 is capable of moving up and down relative to the two movable plates 2 and making that the two movable plates 2 are capable of moving between an unloading state (see FIG. 4) where the two movable plates 2 are away from each other and a loading state (see FIG. 7) where the two movable plates 2 are close to each other.

It is noted that, in some cases, the operation handle 24 may be pushed to make the two movable plates 2 move relative to the pressing cover 1. For example, when the jig 100 is upside down up and down loaded to the guide shielding cage 201 with the heat sink 202, because the pressing cover 1 is placed on a table surface and cannot be pressed and cannot move relative to the two movable plates 2, at this time, the operation handles 24, which outwardly pass through the operation handle avoiding holes 132 of the two movable plates 2 respectively, may be operated and be pushed, so as to make the two movable plates 2 move relative to the pressing cover 1 and grip the guide shielding cage 201.

Referring to FIG. 1 and FIG. 7 to FIG. 8, in the loading state, the jig 100 is capable of stably gripping the guide shielding cage 201 with the heat sink 202 to move together, when the guide shielding cage 201 with the heat sink 202 is assembled to the circuit board 300, the pressing cover 1 continues to be further pressed downwardly by a tool or a machine (not shown), the pressing portions 232 of the two movable plates 2 press each bulge 201i of the two side walls 201c of the guide shielding cage 201 downwardly, so as to make the plurality of inserting legs 201f of the guide shielding cage 201 interferingly pressed into the plurality of inserting holes 301 of the circuit board 300 and make the plurality of inserting legs 201f downwardly inserted into the circuit board 300. In this process, the jig 100 is capable of stably gripping the guide shielding cage 201 with the heat sink 202 to move together, when the connector assembly 200 is assembled to the circuit board 300, the jig 100 directly presses on the pressed protrusions 201h of the side walls 201c of the guide shielding cage 201, and the inner boss 16 of the pressing cover 1 and the heat sink 202 do not contact each other, so that the jig 100 does not press on the heat sink 202 to avoid the heat sink 202 being damaged.

After the connector assembly 200 is successfully assembled to the circuit board 300, the pressing cover 1 may be reversely operated so as to make the two movable plates 2 move to the unloading state, and then the jig 100 is unloaded.

In conclusion, in the present disclosure, the jig 100 for assembling the connector assembly 200 is capable of gripping the guide shielding cage 201 with the heat sink 202 to move together, meanwhile the jig 100 directly presses on the pressed protrusions 201h of the two side walls 201c of the guide shielding cage 201, so as to press the guide shielding cage 201, which has been assembled thereon with the heat sink 202, to assemble the guide shielding cage 201 onto the circuit board 300. Furthermore, the jig 100 does not press on the heat sink 202, so as to avoid the heat sink 202 being damaged. Additionally, because the two movable plates 2 of the jig 100 are capable of passing the heat sink 202, which is larger in width, from up to down and are placed at the outer sides of the two side walls 201c of the guide shielding cage 201, the jig 100 of the present disclosure is capable of being adapted to combination the heat sink 202, which has various wider widths and the guide shielding cage 201. Moreover, a position of the pressed protrusion 201h pressed by the jig 100 is positioned to the lower half portion of the corresponding side wall 201c and is close to the inserting legs 201f, transferring an acting force from the pressing is more direct and a transfer path is short, which can make the inserting leg 201f correctly aligned with and inserted into the corresponding through hole 211 of the circuit board 300, avoid distort deformation of the inserting leg 201f.
