[0045] In a specific embodiment, the included angle between the clamping arm 41 and the fixed arm 42 is less than ninety degrees.

[0046] In one embodiment, gaps are provided between the two sides of the electrical conductor 3 and the two inner walls of the accommodating cavity 12 along the thickness direction of the shell 1, and the two sides of the wire clamping arm 41 protrude from the two sides of the electrical conductor 3 along the thickness direction of the shell 1; the locking end 52 includes two clamping arms 522, which are oppositely and spacedly arranged along the thickness direction of the shell 1, and are respectively located at the two sides of the electrical conductor 3 and correspondingly arranged with the two sides of the wire clamping arm 41; one end of the clamping arm 522 is connected with the operating end 51, and the other end is in abutment with the wire clamping arm 41 through the gap between the electrical conductor 3 and the accommodating cavity 12.

[0047] By providing gaps between the two sides of the electrical conductor 3 and the two inner walls of the accommodating cavity 12 along the thickness direction of the shell 1, the direct contact between the electrical conductor 3 and the shell 1 can be effectively prevented, and the safety risk caused by electrical short circuit or insulation failure is reduced, and the overall safety is improved; the locking end 52 adopts the design of two clamping arms 522, which are respectively located at the two sides of the electrical conductor 3 and correspondingly arranged with the two sides of the wire clamping arm 41, and since the two sides of the wire clamping arm 41 protrude from the two sides of the electrical conductor 3 along the thickness direction of the shell 1, the clamping arm 522 can smoothly abut with the wire clamping arm 41 through the gap between the electrical conductor 3 and the accommodating cavity 12; the two clamping arms 522 are oppositely and spacedly arranged along the thickness direction of the shell 1, so that when the operating element 5 and the stop element 6 are clamped and form effective abutment with the wire clamping arm 41, the electrical wire 2 can smoothly pass through the gap between the two clamping arms 522, and when the stop element 6 is in the unlocked position, the wire clamping arm 41 is reset to rotate towards the electrical conductor 3 under the action of the elastic force until it is in close contact with the electrical conductor 3 and generates sufficient clamping force, thereby firmly clamping the electrical wire 2 passing through the gap between the two clamping arms 522, which not only ensures the stability of the electrical connection, but also improves the reliability of the overall structure.

[0048] In one embodiment, the stop end 62 includes two stop side plates 622, which are oppositely and spacedly arranged along the thickness direction of the shell 1, and each of the two stop side plates 622 is provided with a first clamping hook 621; each of the two clamping arms 522 is provided with a second clamping hook 521, and the two first clamping hooks 621 and the two second clamping hooks 521 correspond one by one.

[0049] By providing two stop side plates 622 on the stop end 62, the two clamping arms 522 are clamped with the two stop side plates 622 respectively in the clamping process, that is, the clamping between the operating element 5 and the stop element 6 is double-protected, and the operating element 5 and the stop element 6 can maintain a stable clamped state under the abutment state of the operating element 5 and the wire clamping arm 41, thereby enhancing the reliability and durability of the overall structure.

[0053] Since the clamping portion 7 protrudes from the electric conductor 3, when the elastic clamping element 4 is in the wire clamping position, the wire clamping arm 41 will directly and stably contact the clamping surface 71 of the clamping portion 7, which enhances the stability of the wire clamping arm 41 when clamping the electric wire, avoids unintended relative sliding between the wire clamping arm 41 and the electric conductor 3, ensures the reliability of the clamping action, and further improves the safety and performance stability of the entire electrical connection system; and since the distance between the clamping surface 71 of the clamping portion 7 and the electric conductor 3 gradually increases in the direction away from the wire inlet hole, when it is necessary to move the wire clamping arm 41 from the wire clamping position to the separation position away from the electric conductor 3, the clamping surface 71 provides a smooth and stable guide slope for the wire clamping arm 41, not only providing a clear path for the movement of the wire clamping arm 41, but also ensuring the stability of the movement process, effectively reducing friction and resistance, thereby facilitating the smooth separation between the wire clamping arm 41 and the electric conductor 3, and ensuring that the interaction between the wire clamping arm 41 and the electric conductor 3 is always in a safe and controllable state during the entire operation cycle.

[0055] The elastic clamping element 4 can be installed and fixed in the shell 1 through the cooperation of the installation groove 14 and the fixing arm 42; by arranging the installation groove 14 in the shell 1 and arranging the installation groove 14 on the side of the wire clamping arm 41 away from the electric conductor 3, the space in the shell 1 is reasonably utilized, and unnecessary interference between the wire clamping arm 41 and the installation groove 14 during operation is avoided, so that the overall structure of the connector is compact and the functions do not interfere with each other; the end of the installation groove 14 close to the wire inlet hole 11 is in communication with the accommodating cavity 12, and such a design enables the fixing arm 42 and the wire clamping arm 41 to be more smoothly installed in the shell 1; the fixing rotating shaft 13 is located at the end of the installation groove 14 in communication with the accommodating cavity 12 and is firmly connected with the groove wall of the installation groove 14, so that the fixing rotating shaft 13 can remain stable when bearing the force generated by the rotation of the wire clamping arm 41 and is not prone to loosening or damage, thereby prolonging the service life of the connector.

[0056] In one embodiment, the shell 1 further comprises a sliding channel 15 in communication with the accommodating cavity 12; the operating element 5 can slide in the accommodating cavity 12 along the sliding channel 15.

[0057] By arranging the sliding channel 15, the movement path of the operating element 5 can be limited, the operating element 5 is guided to travel in a predetermined direction, and the operating element 5 is ensured to move stably and accurately on the given path until it moves to a position where the first clamping hook 621 and the second clamping hook 521 can be clamped, so that the stop element 6 can be accurately clamped with the operating element 5 and be in the locked position.

[0058] Preferably, the operating element 5 is connected in the sliding channel 15 by a spring or other elastic member, so that the operating element 5 can be prevented from falling off the sliding channel 15; when the stop element 6 is in the locked position, the spring or other elastic member is in an elongated state, and when the stop element 6 is in the unlocked position, the spring or other elastic member automatically contracts under the action of the elastic force, so that the operating element 5 is automatically reset.

[0059] In one embodiment, the sliding channel 15 is arranged in an arc shape.

[0060] By arranging the sliding channel 15 in an arc shape, the operating element 5 can be guided to return along a gradual and controllable path, effectively dispersing and relieving the instantaneous impact force generated by the wire clamping arm 41 during elastic resetting, so that when the stop element 6 changes from the locked position to the unlocked position, the operating element 5 will not be directly ejected out of the shell 1 due to the sudden release of the elastic force of the wire clamping arm 41 during elastic resetting, effectively avoiding potential operation failure and safety risk.

[0061] In a specific embodiment, in the initial state, the stop element 6 is in the locking position, and the wire clamping arm 41 is in the separated position under the pushing force of the operating element 5; when starting to clamp the wire, first pass the electric wire 2 through the wire inlet hole 11 and the gap between the two clamping arms 522 in sequence, until the front end of the electric wire 2 contacts the abutting plate 623 on the stop element 6; as the electric wire 2 continues to extend, the interaction between the front end of the electric wire 2 and the abutting plate 623 gradually increases, driving the stop element 6 to rotate, so that the first clamping hook 621 rotates away from the second clamping hook 521 and smoothly separates from the second clamping hook 521, at this time the pushing force of the operating element 5 on the wire clamping arm 41 disappears, the wire clamping arm 41 resets under the elastic force and is in the clamping position abutting against the electric conductor 3, realizing the clamping operation of the electric wire 2; the whole clamping operation process is smooth and efficient, only through the continuous extension of pushing the electric wire 2, the clamping of the electric wire 2 can be realized, without performing any additional actions or steps, simplifying the operation process and improving the operation convenience.
