On the other hand, the insulating shell of the sinker type connector 10 (described in detail below) is formed with two engaging protrusions 112 corresponding to the pair of recesses 201 at the mating opening. When the flat connection object 20 is inserted into the mating opening, the pair of recesses 201 will engage with the two engaging protrusions 112, such as Figure 3 shown.

[0075] Reference Figure 4 and Figure 5 The components of the sinker-type connector 10 according to the embodiment of the utility model are described. Figure 4 is a perspective view of a sinker-type connector 10 according to an embodiment of the present utility model, and Figure 5 1 is an exploded perspective view of a sink-type connector 10 according to an embodiment of the utility model. The sink-type connector 10 includes an insulating housing 11, an operating member 12, a plurality of contacts 13, a plurality of pressing members 14, and two stop members 15.

On the other hand, the flange 111 can completely cover the gap between the insulating housing 11 and the mounting hole 301 to prevent light from leaking from one side of the circuit board 30 to the other side of the circuit board 30.

[0077] Figure 6 1 is a perspective view of an operating member 12 of a submerged connector according to an embodiment of the utility model. The operating member 12 is configured to pivot between an unlocked position and a locked position relative to the insulating housing 11. The operating member 12 has an operating portion 121, a first pivot portion 122, and a second pivot portion 123. The second pivot portion 123 is formed at the end of the operating member 12 and is coaxial with the first pivot portion 122. The operating portion 121 has a sufficient area so that the user can apply force to the operating portion 121 with a finger, thereby pivoting the operating member 12 between the locked position and the unlocked position.

[0078] Figure 7 FIG. 2 is a cross-sectional view of the sunken connector 10 along line AA according to an embodiment of the present invention, wherein the operating member 12 is in a locked position. Figure 7 As shown, the stopper member 15 has a stopper protrusion 151. The stopper protrusion 151 blocks the second pivot portion 123 of the operating member 12 from moving away from the insulating housing 11 along the first direction D1. The stopper member 15 is inserted into an opening formed in the insulating housing 11 in an interference fit manner.

[0079] Figure 8 1 is a cross-sectional view of the submerged connector 10 along line BB according to an embodiment of the present invention, wherein the operating member 12 is in a locked position. The first pivot portion 122 of the operating member 12 is rotatably held by the contact 13 so that the operating member 12 can pivot relative to the insulating housing 11 .

[0080] Fig. 9 FIG. 1 is a cross-sectional view of the sink-type connector 10 along line CC according to an embodiment of the present invention, wherein the operating member 12 is in a locked position.

[0081] In order to allow the flat connection object 20 to be inserted into the sink type connector 10, when the operating member 12 is in the unlocked position, when viewed from the second direction D2, it is ensured that the gap between the top surface of the engaging protrusion 112 and the operating member 12 is larger than the thickness of the flat connection object 20. In order to prevent the flat connection object 20 from being separated from the sink type connector 10, when the operating member 12 is in the locked position, when viewed from the second direction D2, it is ensured that the gap between the top surface of the engaging protrusion 112 and the operating member 12 is smaller than the thickness of the flat connection object 20.

[0082] Fig.10 It is a stereoscopic view of the contact piece 13 of the sunken connector 10 according to an embodiment of the utility model. The contact piece 13 has a main body 130 and a first arm 131 and a second arm 132 extending forward from the front end of the main body 130. A semicircular recess 1311 is formed at the distal end of the first arm 131 as a bearing portion for the first pivot portion 122 of the operating member 12 to abut against. The first arm 131 is formed with a barb 1312 adjacent to the main body 130. The contact piece 13 is firmly held by the insulating housing 11 by inserting the first arm 131 into the opening formed in the insulating housing 11 in an interference fit manner. A contact portion 1321 is formed at the distal end of the second arm 132. The second arm 132 extends into the mating opening SP so that the contact portion 1321 can contact the electrode portion of the flat connection object 20.

[0083] The contact member 13 further includes an extension portion 133 extending upward from the rear end of the main body portion 130 and a connection terminal portion 134 connected to the extension portion 133. The connection terminal portion 134 includes a welding surface 1340 facing the first direction D1. Figures 7 to 9 , the connection terminal portion 134 of the contact 13 extends out from the insulating housing 11 .

[0084] Fig.11 It is a three-dimensional view of the pressing piece 14 of the submerged plate type connector 10 according to an embodiment of the utility model. The pressing piece 14 has a main body 141 and a solder foot 142. The main body 141 is formed with barbs. The groove 113 formed at the end of the insulating shell 11 allows the main body 141 of the pressing piece 14 to be inserted in an interference fit manner. The bottom surface of the insulating shell 11 is also formed with a groove (not shown) for the main body 141 of the pressing piece 14 to be inserted in an interference fit manner. The solder foot 142 of the pressing piece 14 will be welded to the second main surface 303 of the circuit board 30, so that the submerged plate type connector 10 is firmly mounted on the circuit board 30.

[0085] Fig.12 DD is a cross-sectional view of the sinker-type connector 10 according to an embodiment of the present invention, wherein the operating member 12 is in the unlocked position. Fig.12In the figure, the element symbol Df represents the direction of the force applied to the operating portion of the operating member 12 in order to rotate the operating member 12 from the unlocked position to the locked position, and Dn represents the normal direction of the welding surface 1340 of the connecting terminal portion 134 (i.e., the direction of the welding surface 1340 or the direction of the submerged connector). Since the force direction Df and the direction of the welding surface 1340 (normal direction Dn) are parallel to and in the same direction as the first direction D1, the force of the covering operating member 12 will not cause the connecting terminal portion of the contact 13 of the submerged connector 10 to be forced to separate from the welding pad of the circuit board.

[0086] According to the sunken plate type connector of the utility model, the pivot part of the operating member is arranged away from the front end of the insulating housing and the operating member is configured in a rear-lifting manner, so that the direction of the connector can be made to be the same as the direction of the force applied by the closing operating member, thereby avoiding the open circuit problem caused by the connection terminal part being separated from the solder pad as mentioned above. On the other hand, the pivot part is arranged away from the front end of the insulating housing and is aligned with the engaging protrusion in the third direction D3 (when viewed from the second direction D2), thereby avoiding the problem of needing to tilt the flat connection object at a certain angle relative to the first direction D1 in order to insert it into the sunken plate type connector. The operability of inserting a flat connection object (such as a flexible flat cable) into the sunken plate type connector is greatly improved.

[0087] Although the present invention is described with reference to the preferred embodiments, it should be understood that many changes and modifications are possible for those with ordinary knowledge in the technical field to which the present invention belongs without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the disclosed embodiments, but is subject to the text of the claims, that is, equivalent changes and modifications made without departing from the claims of the present invention should still fall within the scope of the present invention.
