The pressing portion 242 of the pressing section 24 is for the user to press , So that the locking section 23 moves down from a locked position where the connector 100 and the docking connector 200 are locked to each other by an elasticity of the elastic section 22 to an unlocked position. In the unlocked position, the connecting rod 231 of the locking section 23 moves downward and the two hooks 233 move downward to release from the two locking holes 203a of the docking connector 200, so that the connector 100 and The docking connectors 200 are unlocked from each other. By integrally constructing the pressing section 24 of the locking section 23 of the locking member 2, the pressing section 24 and the locking section 23 of the locking member 2 will not cause unsmooth unlocking due to tolerance issues. In addition, although in the first embodiment, each hook 233 has two tabs 233a, in other embodiments, the hook 233 may have only one tab 233a, in other words, the hook 233 The specific structure is not limited to this first embodiment.

5, 6, 9 and 10, the pull strap 3 has a connecting section 31 connected to the connecting rod 231 of the locking member 2, and a pull connected to the connecting section 31 for the user to pull Paragraph 32. Pulling the pulling section 32 of the pulling strap 3 can also move the locking section 23 downward from the locked position to the unlocked position, so that the connector 100 and the mating connector 200 are unlocked from each other. With the locking member 2 formed with the pressing section 24 and the pulling belt 3 provided on the connecting rod 231 of the locking member 2, the pressing section 24 pressing the locking member 2 or the pulling section 32 pulling the pulling belt 3 Both can move the connecting rod 231 downward, and move the two hooks 233 downward to unlock. In the first embodiment, a first through hole 221 extending along the left-right direction D2 is formed between the fixing section 21 and the connecting rod 231 of the locking section 23, and the extending section of the pressing section 24 is formed along the A second through-hole 243 extending in the left-right direction D2, the connecting section 31 of the pull strap 3 passes through the first through-hole 221 and the second through-hole 243 and connects the connecting rod 231 around, in detail, the first through-hole 221 In this embodiment, it is formed on the elastic section 22, but it should not be limited to this. The rear wall 12 of the casing 1 is also formed with a through slot 122 lower than the connecting rod 231. The through slot 122 is located in the middle of the rear wall 12 and penetrates back and forth. The pulling section 32 of the pull strap 3 passes through The through slot 122 extends rearwards, and the through slot 122 lower than the connecting rod 231 makes the extending direction of the connecting section 31 of the pull strap 3 closer to the locking section 23 of the locking member 2 to unlock The direction of movement in the process to make it easier to unlock. It should be noted that, in other modified embodiments, the through groove 122 may not be formed in the rear wall 12 but in other places of the housing 1, which is not limited thereto.

3, 4 and 7, in addition, in the first embodiment, the elastic section 22 has two elastic arms 222 on both sides of the first perforation 221 in the left-right direction D2, the rear wall 12 Two evacuation spaces 123 communicating between the accommodating cavity 13 and the two fixing grooves 121 and for avoiding the two elastic arms 222 of the elastic section 22 of the locking member 2 are also formed downward. When the locking section 23 of the locking member 2 moves between the locked position and the unlocked position, the two escaping spaces 123 can allow the two elastic arms 222 of the elastic section 22 to have enough space to deform and lower shift. Specifically, the number of avoidance spaces 123 can be adjusted according to the specific structure of the elastic section 22, and should not be limited to the number in the first embodiment. In addition, the fixing section 21 also has a blocking piece 213 extending forward from the base 211 and used to bear against the top of the rear wall 12. The blocking piece 213 can prevent the locking member 2 from rotating relative to the housing 1, so that the two fixing pieces 212 are not easy to come out of the two fixing grooves 121 and increase the fixing section 21 and the rear wall 12 Holding power.

Referring to FIGS. 1 and 2, the two circuit boards 4 are spaced left and right at the front section of the housing 1 and protrude forward. In the first embodiment, the two circuit boards 4 are located under the top board 11 . When the connector 100 is docked with the mating connector 200, the two circuit boards 4 are respectively inserted into the two slots 201a of the socket 201 of the mating connector 200, and each circuit board 4 is formed on the front stage and used for A plurality of contact fingers 41 that electrically and mechanically contact the terminals 202 of the mating connector 200. It should be noted that in other modified implementations, the electrical connector 100 may not include the circuit board 4, but the housing 1 is provided with terminals 202 or other docking structures. The first embodiment is not used as limit. The cables 5 are electrically and mechanically connected to the circuit boards 4 in the housing 1 respectively. It should be noted that the number of circuit boards 4 and cables 5 can be adjusted according to requirements, and should not be limited to the first embodiment.

Referring to FIGS. 11 to 13, the second embodiment of the connector of the present invention differs from the first embodiment in that the locking member 2 is that the second through hole 243 of the locking member 2 is formed in the pressing section 24 At the front of the pressing portion 242. Further, in other variations, the first through hole 221 and the second through hole 243 can be formed in other positions on the premise that the connecting section 31 of the pull strap 3 can be connected to the connecting rod 231, and even applied to For other fasteners 2 and pull straps 3 with different structures, the fastener 2 may not have the first through hole 221 and the second through hole 243, which is not limited to the above embodiment.

In summary, the present invention uses the locking member 2 formed with the pressing section 24 and the pull strap 3 provided on the connecting rod 231 of the locking member 2 to make the pressing section 24 of the locking member 2 or pull Both the pulling section 32 of the pulling belt 3 can move the connecting rod 231 downward, and the two hooks 233 are moved downward to unlock, and because the pressing section 24 is integrally constructed on the locking section 23 of the locking member 2, the There is no problem of unsmooth unlocking between the pressing section 24 and the locking section 23 of the locking member 2 due to tolerance issues.
