[0026] Embodiment: A direct-insert type side-pressing handle 1 connector includes an insulating member, a metal elastic sheet 2, a handle 1 and a conductive terminal 3. At least one conductive terminal 3 and at least one metal elastic sheet 2 are fixedly installed in the insulating member. One end of the conductive terminal 3 is electrically connected to the metal elastic sheet 2 in a one-to-one correspondence. The metal elastic sheet 2 includes a wire clamping tongue 4, an elastic driving arm 6 and a supporting wall 7. The supporting wall 7 is positioned and fixed in the insulating member. The wire clamping tongue 4 is located on one side of the supporting wall 7 and can move towards the supporting wall 7. The elastic driving arm 6 provides an elastic holding force for the wire clamping tongue 4 towards the supporting wall 7. The wire 24 can be tightly clamped between the wire clamping tongue 4 and the supporting wall 7. At least one handle 1 is installed on the outer side wall of the insulating member and can move within a set range. One end of the handle 1 extends into the insulating member and is connected to the wire clamping tongue 4. The movement of the handle 1 can drive the wire clamping tongue 4 to move away from the supporting wall 7 against the elastic force of the elastic driving arm 6 to release the wire 24.

[0027] One end of the structure handle 1 extends into the insulating part and is connected to the wire clamping tongue piece 4 of the metal elastic sheet 2 to form a linkage structure. When the wire clamping tongue piece 4 of the metal elastic sheet 2 moves relative to the supporting wall 7, the handle 1 will synchronously move with the wire clamping tongue piece 4, ensuring the relative movement stability between the handle 1 and the metal elastic sheet 2, improving the smoothness of wire insertion and the clamping stability of the connector. Multiple handles 1 can be connected into a piece and installed in the product at the same time, or can be installed in the product individually. The assembly of the handle 1 is diversified, with a wide range of applications and high versatility.

[0028] The metal elastic sheet 2 further includes a bottom sheet. The supporting wall 7 is integrally formed and fixed at one end of the bottom sheet. The elastic driving arm 6 is an arc-shaped elastic arm. One end of the arc-shaped elastic arm is integrally formed and fixed at the other end of the bottom sheet. The other end of the arc-shaped elastic arm is fixedly connected to the wire clamping tongue piece 4. A hollowed-out avoidance frame 8 is provided on the bottom sheet. One end of the conductive terminal 3 extends into the metal elastic sheet 2 through the avoidance frame 8 and is attached to the surface of the supporting wall 7 facing the wire clamping tongue piece 4. The metal elastic sheet 2 forms an integrally formed structure, with high overall structural strength, good elasticity, and high clamping stability. During assembly, one end of the conductive terminal 3 passes through the avoidance frame 8 on the bottom sheet and extends into the elastic sheet to achieve clamping connection and conduction with the wire 24.

[0029] One end of the conductive terminal 3 forms a bending structure, and the bending structure just abuts against the end face of the supporting wall 7. This structure enables stable positioning of one end of the conductive terminal 3 and the supporting wall 7, avoiding the detachment of the conductive terminal 3 when inserting the wire 24.

[0030] A fixing piece 9 is provided on the bottom of the metal elastic sheet 2, and a fixing slot is provided on the inner side wall of the insulating part. The fixing piece 9 is press-fitted into the fixing slot of the insulating part. The positioning of the metal elastic sheet 2 is achieved through the tight insertion of the fixing piece 9 and the insulating part. In addition, other structures can also be used to achieve the positioning of the metal elastic sheet 2 and the insulating part, such as riveting, clamping, etc.

[0031] At least one side wall of the wire clamping tongue piece 4 is provided with a bending arc piece 5 whose axis is parallel to the supporting wall 7. One end of the handle 1 is provided with an open-shaped hook 21, and the hook 21 just tightly sleeves the outside of the bending arc piece 5 on the side wall of the wire clamping tongue piece 4. The bending arc piece 5 protruding from the side of the wire clamping tongue piece 4 exerts a force on the side of the hook 21 at one end of the rotating handle 1. When inserting the wire 24, the wire clamping tongue piece 4 of the metal elastic sheet 2 is immediately opened. During the opening process, the handle 1 moves along the track of the insulating part and follows the metal elastic sheet 2 into the insulating part under the action of the clamping force of the bending arc piece 5 of the wire clamping tongue piece 4, so as to realize the linkage cooperation between the handle 1 and the elastic sheet, ensuring the smooth insertion and stable clamping of the wire 24. At the same time, the handles 1 can be assembled and applied in a diversified manner and can be evolved according to the needs of the client.

[0032] The handle 1 includes a fixing portion 10, an elastic deformation portion 11, a pressing portion, and a connecting portion. The fixing portion 10 can be fixedly installed on the insulating member. One end of the elastic deformation portion 11 is connected to the fixing portion 10, and the other end is connected to the pressing portion. The elastic deformation portion 11 can generate elastic deformation. The pressing portion exposes a part outside the insulating member to form a pressing surface. The connecting portion is fixedly connected to the pressing portion, and the connecting portion extends into the insulating member and is connected to the wire clamping tongue 4. During the process of the wire clamping tongue 4 of the metal elastic sheet 2 being opened, while the connecting portion at one end of the handle 1 moves towards the inner side of the insulating member, the fixing portion 10 of the handle 1 is blocked by the insulating member, and the elastic deformation portion 11 of the handle 1 is stretched and deformed, so as to meet the movement stroke of the handle 1. At the same time, when the wire clamping tongue 4 of the metal elastic sheet 2 is closed, the handle 1 can quickly reset.

[0033] An arc-shaped track surface 14 matching its movement track is formed on the surface of the connecting portion of the handle 1. A channel 25 for the connecting portion of the handle 1 to slide through is formed on the side wall of the insulating member. The arc-shaped track surface 14 of the connecting portion of the handle 1 can just closely adhere to the side wall surface of the channel 25 of the insulating member. The movement of one end of the handle 1 is guided through the arc-shaped track surface 14 and the channel 25 on the insulating member.

[0034] At least one of a concave-convex pattern structure 13 and a screwdriver slot 12 is formed on the surface of the pressing portion of the handle 1. The handle 1 can be pressed by pressing the surface of the pressing portion with the concave-convex pattern structure 13 by a finger or by inserting a screwdriver into the screwdriver slot 12. The pressing is convenient and stable.

[0035] The elastic deformation portion 11 on the handle 1 is a bent arc-shaped arm.

[0036] The insulating member includes a plastic body 17 and a plastic cover 18. One end of the plastic body 17 forms an opening structure, and one end of the plastic cover 18 is fixedly inserted into the opening structure at one end of the plastic body 17. The plastic cover 18 and the side wall of the plastic body 17 are fixedly buckled and connected through a buckle structure. An incoming wire socket 27 for inserting a wire 24 is formed at the other end of the plastic body 17, and a socket structure for inserting a plug and facing the conductive terminal 3 is formed at the other end of the plastic cover 18. During assembly, first insert one end of the handle 1 from one side of the plastic body 17, and pre-assemble the metal elastic sheet 2 and the conductive terminal 3 first. One end of the conductive terminal 3 passes through the bottom sheet of the metal elastic sheet 2 from bottom to top and extends into the elastic sheet and is clamped between the wire clamping tongue 4 and the supporting wall 7. Then, integrally install the pre-assembled metal elastic sheet 2 and conductive terminal 3 into the plastic body 17, and connect the metal elastic sheet 2 and the handle 1. The wire 24 is inserted from top to bottom through the incoming wire socket 27 of the plastic body 17, and the wire clamping tongue 4 of the metal elastic sheet 2 is immediately opened. During the opening process, the wire clamping tongue 4 retreats and drives the handle 1 to slide along the plastic body 17 at the same time. After the wire 24 is inserted, it remains in a clamped state under the action of the metal elastic sheet 2 and the elastic deformation portion 11 of the handle 1.

Under the action of the force of the protruding bending arc piece 5 of the wire clamping tongue piece 4, the handle 1 moves inward along the channel 25 of the plastic body 17 together with the wire clamping tongue piece 4, and the elastic deformation part 11 can be stretched in length to meet the movement stroke of the handle 1.

[0039] Method 2: The finger 26 presses the surface of the concave-convex pattern structure 13 of the pressing part of the handle 1, the second hook surface 16 on the other side of the hook of the connecting part of the handle 1 presses the protruding bending arc piece 5 of the wire clamping tongue piece 4, the handle 1 opens the wire clamping tongue piece 4 along the channel 25 of the plastic body 17, and finally the wire 24 is inserted to the bottom along the wire inlet socket 27 of the plastic body 17. When the finger 26 is released, the wire clamping tongue piece 4 of the metal elastic piece 2 clamps the wire 24.

[0040] Method 3: The screwdriver 28 presses the screwdriver slot 12 of the handle 1, the second hook surface 16 on the other side of the hook of the connecting part of the handle presses the protruding bending arc piece 5 of the wire clamping tongue piece 4, the handle 1 opens the wire clamping tongue piece 4 along the channel 25 of the plastic body 17, and finally the wire 24 is inserted to the bottom along the wire inlet socket 27 of the plastic body 17. When the screwdriver is released, the wire clamping tongue piece 4 of the metal elastic piece 2 clamps the wire 24.
