[0045] Embodiment 1:

[0046] As Figures 1 to 5As shown in the figure, the unlocking structure of the electrical connector provided in this embodiment is used for locking and unlocking the electrical connector. The electrical connector includes an insulating body 6, and the insulating body 6 has a channel 4. The unlocking structure of the electrical connector includes a locking part 3, a pulling belt 1, and a limiting part 2. Both the locking part 3 and the limiting part 2 are arranged on the front side of the insulating body 6 of the electrical connector. In this embodiment, the limiting part 2 is integrally formed with the insulating body 6. The limiting part 2 is arranged in the channel 4, and the pulling belt 1 passes through the channel 4 and is connected to the locking part 3. The upper side surface of the limiting part 2 is flush with the upper side surface of the insulating body 6. In other embodiments, the upper side surface of the limiting part 2 may also be located inside the insulating body 6. By placing the limiting part 2 inside the insulating body 6 so that its upper side surface does not protrude from the upper side surface of the insulating body 6, the thickness of the electrical connector is reduced and the space occupation is decreased. The use of the limiting part 2 integrally formed with the insulating body 6 is simple to manufacture and has strong connection stability. The limiting part 2 plays a role in limiting the pulling belt 1 to prevent the pulling belt 1 from detaching. Combining with the setting of the channel 4, the direction of the pulling belt 1 is changed so that the pulling belt 1 can be attached to the upper side surface of the insulating body 6, reducing the space occupation. When unlocking, pull the pulling belt 1 backward to drive the locking structure of the locking part 3 to swing backward for unlocking. By using the pulling belt 1 to unlock, there is no need to directly press the locking part 3 by hand, and rapid unlocking can be achieved even when the gap between adjacent electrical connectors is very small.

[0047] Among them, the locking part 3 includes a base body 31 and a pulling belt connecting part 32. The base body 31 includes a fixing part 311, a connecting arm 312, a pressing part 313, and a clamping point 314. The connecting arm 312 is bent and its two ends are respectively connected to the pressing part 313 and the fixing part 311 to form a U-shaped structure. A number of clamping points 314 are arranged on the pressing part 313. The pulling belt connecting part 32 extends upward from the top end of the pressing part 313 and is bent forward. The pulling belt connecting part 32 has a connecting hole 33, and the pulling belt 1 passes through the channel 4 and is connected to the connecting hole 33. The use of only one connecting hole 33 is more convenient than the way of winding with two connecting holes 33 and is more conducive to the passing of the pulling belt 1.

[0048] Among them, the pulling belt connecting part 32 includes an extension arm 321 extending upward from the top end of the pressing part 313, an inclined arm 322 inclined forward from the extension arm 321, and a bent part 323 bent forward and extending backward from the end of the inclined arm 322. The connecting hole 33 is arranged on the extension arm 321. By arranging a connecting hole 33 on the extension arm 321 instead of on the inclined arm 322 or the bent part 323, combined with the setting of the inclined arm 322, it is not only beneficial to the connection of the pulling belt 1 but also plays a guiding role for the pulling belt 1. The bent part 323 plays a protective role for the pulling belt 1 to prevent damage to the pulling belt 1 caused by the tip.

[0049] The upper side surface of the strap connection part 32 of this embodiment is located inside the insulating body 6. In other embodiments, the upper side surface of the strap connection part 32 may also be flush with the upper side surface of the insulating body 6. By setting like this, not only the upper side surface of the limiting part 2 does not protrude from the upper side surface of the insulating body 6, but also the upper side surface of the strap connection part 32 does not protrude from the upper side surface of the insulating body 6, reducing the thickness of the electrical connector.

[0050] Among them, the limiting part 2 has a first guiding surface 5, which guides the strap 1, improves the smoothness of pulling the strap 1, reduces the damage to the strap 1, and improves the service life of the strap 1.

[0051] Embodiment Two:

[0052] As Figures 6 to 7 shown, this embodiment provides an electrical connector, including an insulating body 6, a conductive terminal group 7, a wire 8, and the unlocking structure of the electrical connector in Embodiment One. The conductive terminal group 7 is arranged inside the insulating body 6, the wire 8 is electrically connected to the conductive terminal group 7, and the unlocking structure of the electrical connector is arranged outside the insulating body 6. The insulating body 6 includes a first shell 61 and a second shell 62, and the first shell 61 and the second shell 62 are snap-fitted. The first shell 61 has a lock slot 63, the lock part 3 is installed in the lock slot 63, the second shell 62 abuts against the top end of the lock slot 63, the channel 4 of this embodiment is arranged on the second shell 62, and the second shell 62 has a limiting slot 64 for limiting the lock part 3.

[0053] Among them, the channel 4 has a second guiding surface 9, which guides the strap 1, improves the smoothness of pulling the strap 1, reduces the damage to the strap 1, and improves the service life of the strap 1.

[0054] Embodiment Three:

[0055] This practical embodiment provides a connector assembly, including the electrical connector in Embodiment Two and a docking connector docked with the electrical connector.

[0056] Embodiment Four:

[0057] As Figures 8 to 9 shown, the difference between this embodiment and Embodiment One is:

[0058] The limiting part 2 and the lock part 3 are integrally formed. Specifically, the lock part 3 further includes a limiting part 2 extending upward from the top end of the fixing part 311. By setting the limiting part 2 integrally formed with the lock part 3, the production is simple and the connection stability is strong.

[0059] Embodiment Five:

[0060] As Figures 10 to 11 shown, the difference between this embodiment and Embodiment One is:

[0061] The limiting part 2 of this embodiment is detachably connected to the insulating body 6. Specifically, the limiting part 2 is installed in the locking groove 63, and the top end of the limiting part 2 abuts against the second shell 62, and the bottom end of the limiting part 2 abuts against the top end of the fixing part 311. The limiting part 2 with a split design can be installed by selecting limiting parts 2 with different shapes and specifications according to requirements, with strong applicability.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
