(8) Please refer to FIG. 1, which is a structural schematic diagram of a connector according to a first embodiment of the invention. In FIG. 1, a connector 10 can be used for connecting a cable 4 and a circuit board 2. The upper diagram of FIG. 1 is a state where the connector 10 latches the cable 4, and the lower diagram of FIG. 1 is a state where the connector 10 is released from the latched cable 4.

(9) Referring to FIG. 2 as well, it is an exploded view diagram of the connector in FIG. 1. The connector 10 includes an upper cover plate 12, a lower plate body 14, and an auxiliary member 20. Wherein the upper diagram of FIG. 2 discloses the structure of the upper cover plate 12, the middle diagram of FIG. 2 discloses the structure of the lower plate body 14 and the lower diagram of FIG. 2 discloses the structure of the terminals 16, the holding member 18, and the auxiliary member 20.

(10) The upper cover plate 12 has a surface and an edge. Openings 122 are respectively formed on two sides of the surface adjacent to the edge. In addition, an extension arm 124 is formed on the edge of the upper cover plate 12. A fastening member 126 is formed on an outer side of the extension arm 124. A first connecting member 1242 is formed on the outer side of the extension arm 124. The fastening member 126 is a lug or a bump. Here, the first connecting member 1242 may be a through hole on the extension arm 124 or in other types.

(11) The lower plate body 14 is connected to the upper cover plate 12. The lower plate body 14 provides an accommodation space SP to accommodate the cable 4. The lower plate body 14 comprises a terminal slot 142, an actuation slot 144, and a rotating base 146. The terminal slot 142 and the actuation slot 144 are formed in the accommodation space SP.

(12) The terminal slot 142 is used for disposing terminals 16, and the actuation slot 144 is used for disposing a holding member 18. The structure of the holding member 18 can be referred to the structure disclosed in the cross-sectional diagram of FIG. 4. The holding member 18 may be an independent element or a member extending from the upper cover plate 12. Here, the latter is taken as an example.

(13) Returning to FIG. 2, the rotating base 146 is formed on a side of the actuation slot 144 and provides a second connecting member 1462. Here, the second connecting member 1462 may be a protruding post on the rotating base 146 or in other types. Therefore, the rotating base 146 is coupled to the through hole of the extension arm 124 by the protruding post.

(14) In another embodiment, the types of the first connecting member 1242 and the second connecting member 1462 may be used interchangeably. That is, the first connecting member 1242 may be a protruding post and the second connecting member 1462 may be a through hole. The holding member 18 is disposed at a position in the actuation slot 144 corresponding to the position of the opening 122. The rotation base 146 is disposed corresponding to the extension arm 124. In addition, the actuation slot 144 may form a stopper 1442. When the upper cover plate 12 and the lower plate body 14 are combined, the stopper 1442 is adjacent to the opening 122.

(15) The auxiliary member 20 is disposed on the lower plate body 14 and is coupled to the rotating base 146. Here, the auxiliary base 20 engages with the rotating base 146 in a pin (or embedded) manner. Referring to the upper diagram of FIG. 3, which shows a detailed structure of the auxiliary member 20. The auxiliary member 20 further includes a joint part 204 and a buckle part 202. The joint part 204 is connected to the buckle part 202. The joint part 204 engages the rotation base 146, so that there is a gap between the buckle part 202 and the rotation base 146, which can accommodate the extension arm 124.

(16) As shown in the lower diagram of FIG. 3, which is a schematic diagram illustrating the connection of the first connecting member and the second connecting member according to an embodiment of the invention. The upper cover plate 12 may be combined with the lower plate body 14 by engaging the first connecting member 1242 with the second connecting member 1462.

(17) In another embodiment, the auxiliary member 20 further includes a fixing part 206 for locking the lower plate body 14 to the circuit board 2. In addition, when the buckle part 202 is an opening, the buckle part 202 (such as an opening) is buckled by the fastening member 126 (such as a lug or a bump), so that the angle between the upper cover plate 12 and the lower plate body 14 may be preserved at or near 0 degree.

(18) Referring to FIG. 4, which is a schematic cross-sectional diagram taken along A-A′ of the connector in FIG. 1. In the latch diagram in the upper diagram of FIG. 4, when the upper cover plate 12 is combined with the lower plate body 14, the rotating base 146 is fasten by the fastening member 126 (for example, rotate counterclockwise) so that the upper cover plate 12 is stably fasten with the lower plate body 14. Moreover, please also refer to the unlatched schematic diagram in the lower diagram of FIG. 4 together.

(19) When the cable 4 is inserted into the accommodating space SP, the holding member 18 can hold the cable 4 in the accommodating space SP. The holding member 18 is squeezed by the cable 4 so that a part of the holding member 18 protrudes from the opening 122. When an external force (that is, a pulling force or wrenching) is applied to the upper cover plate 12, an angle is formed between the upper cover plate 12 and the lower plate body 14, and the holding member 18 is further deformed to release the cable 4.

(20) The invention has been disclosed above with embodiments. However, the skilled in the art should understand that the embodiments are only used to describe the invention and should not be interpreted as limiting the scope of the invention. It should be noted that all changes and substitutions equivalent to the embodiments should be included in the scope of the invention. Therefore, the scope of protection of the invention shall be defined by the scope of the patent application claims.
