The electrical connector also includes a pick-up cover mounted on the protective cover and used for suction. The pick-up cover can position and combine a plurality of insulating bodies in At the same time, it improves the alignment of the terminal and the chip module paired after the combined electrical connector is welded to the circuit board as a whole, and at the same time, the size of the connector after the welded board can be regulated. However, since the mounting directions of the pick-up cover and the protective cover are both vertical, it is easy to remove the protective cover while removing the pick-up cover after welding, which causes inconvenience in use.

Therefore, it is indeed necessary to provide a new electrical connector and its pickup cover to overcome the above-mentioned drawbacks.

The purpose of the present invention is to provide an electrical connector and its pick-up cover which are easy to operate.

In order to achieve the above objective, the present invention can be achieved by adopting the following technical solutions: an electrical connector defined with a horizontal direction and a vertical direction, the electrical connector includes two bases and a protective cover installed on each base, And a pick-up cover, each seat body holds a conductive terminal; the two seat bodies are arranged side by side in a horizontal direction, the protective cover is installed above the corresponding seat body, and the protective cover is assembled along the horizontal direction To the seat body, the pickup cover is installed on the protection cover along the vertical direction, and the pickup cover is installed on the two protection covers at the same time.

In order to achieve the above object, the present invention can also be achieved by adopting the following technical solutions: a pick-up cover is used to assemble a protective cover provided on an electrical connector, and the electrical connector can be moved by vacuum suction. The pick-up cover It includes a longitudinal main body plate, first and second clamping portions located at both ends of the main body plate respectively, and third and fourth clamping portions located in the middle of the main body plate. The first and third clamping portions have facing each other Catch hooks, the second and fourth clamping portions have hooks facing each other, and each pair of hooks facing each other is clamped at the longitudinal ends of the protective cover in a vertical direction.

Compared with the prior art, the protective cover of the electrical connector and its pick-up cover of the present invention is installed horizontally to the insulating body, and the pick-up cover is installed vertically to the protective cover. The protective cover will not be damaged when the pick-up cover is removed from the protective cover. It can be removed together to ensure the independence of the operation of the protective cover and the pick-up cover; at the same time, the pick-up cover There are vent holes and an overhead bracket to make it incompletely adhere to the protective cover, and the resulting overhead layer can achieve the effect of ventilation and heat dissipation, reducing the empty soldering caused by the solder balls not being melted at the same time during soldering.

In this way, the hook 48 and the boss 49 abut against the inner recessed portion 310 or the outer recessed portion 320, so that the pickup cover 4 can be firmly installed in the vertical direction. The protective cover 3 is on. As shown in the sixth figure, the hooks 48 of the first and third holding parts 44, 46 are arranged face to face with each other, and the hooks 48 of the second and fourth holding parts 45, 47 are arranged face to face with each other In this way, each pair of the hooks 48 facing each other is clamped on the two longitudinal ends of the protective cover 3 in the vertical direction. The pick-up cover 4 is provided with a stopper 421 extending facing the protective cover 3, and the stopper 421 is clamped at the lateral ends of the outer recess 320, thereby positioning the pick-up cover 4 in the lateral direction. On the protective cover 3.

Referring to the first to fourth figures, the picking cover 4 is provided with a limiting protrusion 422 protruding downwards corresponding to the joint 300 of the pair of protective covers 3, and the limiting protrusion 422 includes facing the joint 300 A limiting strip 4220 extending in a narrow and long shape is clamped between a pair of the protective covers 3. The limit bar 4220 can play a buffering effect between the two protective covers 3 when the pickup cover 4 is installed to the protective cover 3. In a preferred embodiment, the pick-up cover 4 is provided with a bracket 420 corresponding to the splicing place 300, and the limiting protrusion 422 protrudes downward from the above-mentioned bracket 420 at the splicing place 300. The pickup cover 4 also includes a pair of grabbing portions 401 protruding upward from the pickup surface 41. It is convenient to remove the pickup cover 4 after the electrical connector 100 is welded. In this embodiment, the grabbing portion 401 is provided corresponding to the second vent 40.

Focusing on the second and sixth figures, the two spliced seat bodies 1 define an outer edge 10, and the four corners of the outer edge 10 are protruding upwards and are provided with substantially "L" shaped stops. Stop 11, the protective cover 3 is provided with a first limiting edge 33 extending downward in the vertical direction at the outer edge 111 of the protective cover 3 corresponding to the stop 11, and the stop 11 is used in the longitudinal direction The upper stop the first limiting edge 33 to limit the sliding range of the protective cover 3 and to position the protective cover 3 in the lateral direction. The protective cover 3 is further provided with a second limiting edge 34, the second limiting edge 34 includes a vertical portion 341 extending in the vertical direction down to the thickness of the seat body 1 and connecting the vertical portion 341 The end of the straight portion 341 is a horizontal portion 342 that extends horizontally toward the inner direction of the seat body 1. The protective cover 3 installed on the base 1 is restricted in the vertical direction.

In summary, it can be seen that the two protective covers 3 in the electrical connector and its pick-up cover of the present invention are mounted on the base 1 by sliding in the horizontal direction, and the upper limit of the protective cover 3 in the vertical direction is at the same time. The seat body 1; the pickup cover 4 passes through the first, second, third, and fourth clamping portions 44, 45, 46, 47 and the inner recessed portion 310 or the outer recessed portion 320 in the vertical direction The pick-up cover 4 and the protective cover 3 have different installation operation directions, so that the protective cover 3 will not be installed when the pickup cover 4 is removed from the protective cover 3 Being removed together can ensure the independence of the operation of the protective cover 3 and the pick-up cover 4, which greatly increases the convenience of the electrical connector 100 in use.
