The insulating housing 10 has a mounting cavity 11 therein, and a wire insertion hole H communicating with the mounting cavity 11 is provided in a side surface thereof.

As shown in fig. 3 and 8, the wire clamping spring 20 includes a base 21 and a tilting arm 22 having a U-shaped structure formed by a first arm 21a, a second arm 21b and a bending arm 21c, and the bending arm 21c is sleeved on a rotating shaft Z1 of the insulating housing 10 in the mounting cavity 11, so that a vertical rotatable shaft connection is formed between the wire clamping spring 20 and the insulating housing 10.

Referring again to fig. 4, the first arm 21a is located above the second arm 21b, and the free ends of the first arm 21a and the second arm 21b are spaced apart from each other to form a first opening V1, i.e., an opening of the base 21. The tilting arm 22 extends outwards from the first arm 21a at a certain angle, and a clamping groove J with a second opening V2 is formed between the tilting arm 22 and the first arm 21a, and the opening direction of the second opening V2 is consistent with that of the first opening V1.

As shown in fig. 2 and 3, the operating handle 30 is pivotally connected to the upper side of the insulating housing 10, the operating handle 30 includes a handle portion 31 and an action portion 32, and the action portion 32 extends into the mounting cavity 11 through the escape hole K in the upper portion of the insulating housing 10 and extends toward the clip slot J between the clip spring 20 side, the tilting arm 22 and the first arm 21a.

As shown in fig. 4 and 5, when the handle 31 is lifted, the operating handle 30 rotates upward, the acting portion 32 rotates upward and extends into the clamping groove J, acts upward on the lifting arm 22 along the inner side of the lifting arm 22 and pushes it upward to drive the wire clamping spring 20 to rotate upward, and at this time, the end of the second arm 21b is far away from the conductor 101 below, and a wire insertion channel R corresponding to the wire insertion hole H is formed between the second arm 21b and the conductor 101.

As shown in fig. 2 and 9, in the present embodiment, the number of the wire insertion holes H of the single quick electric connector 100 is one, and accordingly, the wire insertion channels R are one, so that one wire P can be inserted into the opened wire insertion channel R from the wire insertion hole H, and further, electrically connected with the electrical conductor 101, and the quick electric connector set 200 is formed by splicing a plurality of quick electric connectors 100, so that electrical connection is formed between the electrical conductors 101 of each quick electric connector 100, and further, various serial-parallel connection wire modes are realized.

In other embodiments, the number of wire insertion holes H of the single quick electrical connector 100 may be more than one, and accordingly, the number of wire insertion channels R corresponds to the number of wire insertion holes H for inserting more than one wire to achieve electrical connection in multiple connection modes. Typically, for example, one wire insertion hole is formed on each opposite side of the insulating housing 10, one wire insertion channel for each wire insertion hole, and one electrical conductor is commonly used for the two wire insertion channels, so that the two wires are electrically connected in series inside the single quick electrical connector 100.

As shown in fig. 3 and 6, when the handle 31 is pressed down, the operating handle 30 rotates down, the acting portion 32 rotates down and presses down the first arm 21a to drive the clip wire spring 20 to rotate down, at this time, the end of the second arm 21b is close to the conductor 101, and the acting portion 32 abuts against the first arm 21a.

When the wire P is inserted into the wire insertion path R, the tip of the first arm 21a presses the wire P against the conductor 101 by the pressing of the action portion 32, so that an electrically conductive electrical connection is produced between the wire P and the conductor 101. And when no wire is inserted into the wire insertion path R, the tip of the first arm 21a contacts the conductor 101 to close the wire insertion path R.

In the above operation, the handle portion 31 and the acting portion 32 of the operation handle 30 form a first lever with a pivot point therebetween as a pivot point, the first arm 21a and the tilting arm 22 of the wire clamping spring 20 form a second lever with the rotation axis Z1 as a pivot point therebetween, and the two sets of levers form a linkage with the clamping groove J formed between the first arm 21a and the tilting arm 22 of the wire clamping spring 20 by extending the acting portion 32 of the operation handle 30 into the pivot.

The force of the user lifting the handle portion 31 is sequentially transmitted to the tilting arm 22-the bending arm 21 c-the second arm 21b of the second lever through the handle portion 31-the action portion 32 of the first lever, and the force of the user pressing the handle portion 31 is sequentially transmitted to the first arm 21 a-the bending arm 21 c-the second arm 21b of the second lever through the handle portion 31-the action portion 32 of the first lever, so that the user can operate the handle portion 31 more effort-saving.

In addition, when the wire insertion channel R is to be opened for inserting the wire P, the user only needs to lift the handle portion 31, rotate the acting portion 32 upwards and lift the tilting arm 22 upwards to drive the wire clamping spring 20 to rotate upwards, and at this time, the user can insert the wire P into the wire insertion channel R from the wire insertion hole H without continuously applying additional force to maintain the lifted state of the end of the second arm 21 b.

In this embodiment, as shown in fig. 8, the base 21 and the tilting arm 22 are integrally formed, and the tilting arm 22 is a straight arm extending in an acute angle direction with respect to the first arm 21a. Specifically, the wire clip spring 20 is formed by integrally stamping and bending a strip-shaped sheet, the strip-shaped sheet is bent to form an intermediate body with a U-shaped structure, one free arm of the intermediate body, namely the first arm 21a in the embodiment, is stamped with a U-shaped split line F with an inward opening, and the tilting arm 22 is formed by bending a solid body inside the U-shaped split line F upwards.

The wire clamping elastic sheet 20 formed by integral stamping and bending not only has high efficiency and economy of the production process, but also can fully exert the elastic deformation capability of the strip-shaped sheet formed between the two free arms of the U-shaped structure-like base body 21 after stamping and bending so as to tightly clamp the wire, ensure the wire P to be fully contacted with the conductor 101 and reduce the contact resistance. Meanwhile, the continuity of force conduction between the parts of the integrally formed strip-shaped sheet material and the parts of the integrally formed strip-shaped sheet material is fully utilized, so that the labor-saving effect is further generated.

Further, as shown in fig. 6 and 8, the outer end of the second arm 21b is bent away from the first arm 21a to form an outer expansion section 23, so as to increase the included angle between the conductor 101 and the second arm 21b, thereby enhancing the clamping force of the second arm 21b and the conductor 101 for clamping the wire P, and preventing the wire P from coming out from the two to cause the electrical connection to break.

As shown in fig. 3, the handle portion 31 of the operating handle 30 and the extending direction of the acting portion 32 form an acute angle, so that the operating handle 30 has a pair-hook-like configuration. Referring again to fig. 1 and 7, the outer end of the shank 31 is provided with a slope 33 inclined from the outer end to the inner end, so that a gap Q can be formed between the slope 33 and the insulating housing 10 when the shank 31 is in a depressed state. Through this notch Q, the user can pick up the handle 31 with his finger tip.

As shown in fig. 4 to 7, the acting portion 32 is beak-shaped and includes a first surface 32a on the inner side and a second surface 32b on the outer side, the first surface 32a and the second surface 32b are disposed at a second acute angle A2, the top end of the acting portion 32 is an arc abutting surface 32c, when the operating handle 30 rotates upwards, the acting portion 32 extends into the clamping groove J, and the first surface 32a and the arc abutting surface 32c act on the tilting arm 22 forwards and backwards; when the operating handle 30 is turned down, the second surface 32b first pushes down the first arm 21a, the acting portion 32 gradually exits the clamping groove J, and the circular arc abutting surface 32c slides down along the first arm 21a and abuts against the first arm 21a.

Accordingly, the front-rear operation sequence engagement is formed between the first surface 32a, the circular arc abutting surface 32c and the second surface 32b of the operation portion 32 and the tilting arm 22 and the first arm 21a, and the third lever using the dynamic operation point of the first lever and the second lever as the pivot is formed between the operation portion 32 and the tilting arm 22 and the first arm 21a, thereby achieving the labor-saving effect while the linkage engagement is formed.

Further, as shown in fig. 5, the clamping groove J formed by the tilting arm 22 and the first arm 21a forms a first acute angle A1, and the first acute angle A1 is greater than the second acute angle A2, so as to ensure that the first surface 32a, the circular arc abutting surface 32c and the second surface 32b in the third lever linkage process can cooperate with the tilting arm 22 and the first arm 21a in the aforesaid sequential order, and prevent the action part 32 from being blocked in the clamping groove J in the linkage process.

Accordingly, as shown in fig. 6, the inner side surface of the handle 31 abuts against the first limiting portion B1 to limit the downward rotation of the operating handle 30, preferably, when the operating handle 30 is rotated down to the lower limit, the handle 31 is horizontal, so that the insulating housing 10 is substantially rectangular when the wire insertion path R is closed or the wire P is clamped, and the appearance flatness is good.

As shown in fig. 4 and 9, the outer side surface of the operating handle 30 abuts against the second limiting portion B2, and/or the outer side surface of the tilting arm 22 abuts against the third limiting portion B3, so as to limit the upward rotation amplitude of the operating handle 30.
