For further description of the thin lock-and-unlock connector 10, please refer to Figure 2 , the first housing 12 and the second housing 14. Figure 1 , the first housing 12 and the second housing 14. Figure 8 , the first housing 12 and the second housing 14.

[0121] For further description of the thin lock-and-unlock connector 10, please refer to Figures 3(a) to 3(c) , the first housing 12 and the second housing 14. Figure 2 , the first housing 12 and the second housing 14. Figure 2 , the first housing 12 and the second housing 14. Figure 2 , the first housing 12 and the second housing 14. Figure 2 , the first housing 12 and the second housing 14.

[0126] In another embodiment, the first body 122 further comprises a plurality of seventh fixing members 1268. In this embodiment, the number of the seventh fixing members 1268 is exemplified by two. The seventh fixing members 1268 protrude from the first fixing portion 126 in a direction which is approximately perpendicular or perpendicular to the direction in which the first fixing members 1262 and the third fixing members 1264 extend.

[0127] In another embodiment, a plurality of first gaps 1210 is formed between the first body 122 and the first pressing portion 124 to partially separate the first body 122 and the first pressing portion 124, so that the first pressing portion 124 can easily deform under an external force.

[0128] In another embodiment, the first body 122 forms a positioning opening 1214 for corresponding to the positioning post 1616 mentioned later.

[0129] Referring to Figures 4(a) to 4(c) for illustrating the present application Figure 2 of the second housing. Fig. 4(a) is a bottom view illustrating the present application Figure 2 of the second housing; Fig. 4(b) is a top view illustrating the present application Figure 2 of the second housing; and Fig. 4(c) is a side view illustrating the present application Figure 2 of the second housing.

[0130] The second housing 14 comprises a second body 142, a plurality of second pressing portions 144 and a plurality of second fixing members 146. In this embodiment, the number of the second pressing portions 144 and the second fixing members 146 is exemplified by two.

[0131] The second pressing portions 144 and the second fixing members 146 are respectively arranged on two sides of the second body 142. The second pressing portions 144 connect the second fixing members 146 and the second body 142. The second pressing portions 144 correspond to the first pressing portions 124. The second pressing portions 144 provide a first locking member 1442 and a first elastic member 1444. The second fixing members 146 connect the first elastic member 1444 and the second fixing members 146 correspond to the first fixing members 1262. Referring to Figure 6 the drawings, it can be seen that the first fixing members 1262 are limited by the second fixing members 146.

[0132] In another embodiment, the second housing 14 further comprises a plurality of fourth fixing members 1410. In this embodiment, the number of the fourth fixing members 1410 is exemplified by four.

In addition, each of the first locking members 1442 further comprises a first elastic arm 14422 and a first clamping block 14424. The first clamping block 14424 protrudes from the first elastic arm 14422 and the first clamping block 14424 is accommodated in a first accommodating space SP1 to be capable of corresponding to a notch (not shown) of a flexible printed circuit board (not shown). The first elastic arm 14422 corresponds to the first inclined surface S1. In this embodiment, the first elastic member 1444 is exemplified by a U-shaped body, and in other embodiments, as long as an elastic structure can be formed, it belongs to the elastic member of the present application.

[0134] In another embodiment, the second pressing portion 144 further forms a plurality of pressing pieces 1446. The pressing pieces 1446 correspond to the first pressing portion 124. The pressing pieces 1446 are closer to the first pressing portion 124 than the first locking members 1442 and the first elastic members 1444, so that the second pressing portion 144 contacts the first pressing portion 124 earlier than the first locking members 1442 and the first elastic members 1444.

[0137] The third body 162 provides a first surface 1622, a second surface 1624, and a first accommodating space SP1. The first surface 1622 is combined with the first shell 12 and the second surface 1624 is combined with the second shell 14.

[0138] The first actuating part 164 and the sixth fixing member 166 are respectively disposed on both sides of the third body 162. The first actuating part 164 is provided corresponding to the first locking member 1442, and the first accommodating space SP1 accommodates a portion of the first locking member 1442, that is, a portion of the first latching block 14424. The first actuating part 164 forms a first inclined surface S1 to determine the deformation stroke of the first locking member 1442, such that the first locking member 1442 stops at the first inclined surface S1, and the sixth fixing member 166 corresponds to the fifth fixing member 1266.

[0139] In another embodiment, the third body 162 further includes a plurality of second openings 168. A seventh fastener 1268 is provided corresponding to the second openings 168. Furthermore, the seventh fastener 1268 engages with the second openings 168 to limit the first housing 12 within the third body 162.

[0140] In another embodiment, the third body 162 further includes forming a plurality of first grooves 1610. Here, the number of first grooves 1610 is illustrated by example as two. The first grooves 1610 engage with the fifth fastener 1266 to confine the fifth fastener 1266 within the third body 162.

[0141] In another embodiment, the first insulator 16 further includes a plurality of eighth fasteners 1612. Here, the number of eighth fasteners 1612 is illustrated as four. The eighth fasteners 1612 are provided corresponding to the fourth fasteners 1410 to confine the second housing 14 within the first insulator 16.

[0142] In another embodiment, the third body 162 further includes a positioning post 1616 disposed corresponding to the positioning port 1214 of the first housing 12. The positioning post 1616 is inserted into the positioning port 1214 to confine the first housing 12 to the first insulator 16.

[0143] Please refer to the above. Figure 6 This invention is described. Figure 1 A side cross-sectional view of the slimmed-down latch and unlocking connector. Figure 6 In this context, based on the first housing 12, the second housing 14, and the first insulator 16 mentioned above, it can be understood that the combination of the first fixing member 1262, the second fixing member 146, the fifth fixing member 1266, the sixth fixing member 166, and the first elastic member 1444 enables the first housing 12, the second housing 14, and the first insulator 16 to be interlocked.

[0144] The first pressing portion 124 is deformed in a first direction, for example, as shown in FIG. 3(c), the first direction is the direction of the negative Y-axis (the drawing faces downward). After the first pressing portion 124 is deformed, the first elastic member 1444 is further driven to deform the first locking member 1442 in a second direction, for example, as shown in FIG. 4(c), the second direction is the direction of the positive Y-axis (the drawing faces upward), so that after the first locking member 1442 is deformed, it can unlock the flexible printed circuit board (not shown in the drawing) located in the first accommodating space SP1, and when the first elastic member 1444 is not deformed, the first locking member 1442 locks the flexible printed circuit board in the first accommodating space SP1.

[0145] Reference can be made to Figure 7 for the purpose of illustrating the Figure 1 thin locking and unlocking connector. In Figure 7 , the first acting portion 164 is shown as a first inclined surface S1 structure, so that when an external force is applied to the first pressing portion 124 of the first housing 12, that is, the external force is applied to the first pressing portion 124 in the direction of the drawing facing downward, the first pressing portion 124 indirectly presses the pressing sheet 1446 to deform the first elastic member 1444, and then drives the first locking member 1442 to deform. At this time, the deformation stroke of the first locking member 1442 is limited by the first inclined surface S1.

[0146] Returning to FIG. 3(b) and FIG. 4(c), after the first locking member 1442 is deformed in the second direction, at least a part of the first locking member 1442 protrudes from the first opening 128 of the first housing 12 mentioned above. By the structure of the first opening 128, the connector can achieve the purpose of thinning.
