The movable member 40 has a relief 413 into which a wire of the wire rod 101 is inserted.

Note that the fact that the core of the wire 101 is not inserted means that the core of the wire 101 is not clamped to the conductor 20 by the clamping member 30. Insertion of the core of the wire 101 in place means that the core of the wire 101 is clamped on the electrical conductor 20 by the clamping member 30.

At the time of wire taking, the movable member 40 is pressed so that the movable member 40 and the clamping member 30 are engaged again, the wire 101 is taken out, and the wire connection passage 10c is kept open again to wait for the next wire connection. Thus, the opening of the wiring channel 10c is completed in the wire taking process, and the wire taking efficiency is greatly improved.

To improve the assembly efficiency of the electrical connector and save the manufacturing cost, referring to fig. 9 and 19, in some embodiments, the clamping member 30 may be an integrally formed spring plate. Therefore, impact force can be formed due to sudden rebound of the elastic sheet when wiring, so that sound reminding is realized when the wiring is in place, the convenience of wiring is further improved, and the condition that the wiring is not in place is avoided.

Referring to fig. 3, 7 and 9, in the present embodiment, the spring plate may include a main body section 31, a clamping section 32, an ejector section 33 and a locking pin section 34; one end of the main body section 31 is connected with the clamping section 32 and an arc-shaped part 311 is formed at the connection part, and the arc-shaped part 311 surrounds the limit post 11 in the mounting groove 10b; in the open position, a connection channel 10c is formed between the clamping section 32 and the electrical conductor 20; in the clamping position, the clamping section 32 clamps the core of the wire 101 to the electrical conductor 20; the other end of the main body section 31 is connected with the ejector section 33, the lock pin section 34 is used for being clamped with the movable piece 40 when the wire core of the wire 101 is not inserted in place, a normally open state of the wiring channel 10c is formed, the ejector section 33 is used for being deformed under the pushing of the wire core of the wire 101 and enabling the lock pin section 34 to be separated from the clamping state of the movable piece 40, and at the moment, an electric connection state of the clamping wire 101 is formed.

The utility model can realize the wiring function without assisting wiring by means of a specific tool by adopting the elastic sheet structure and matching the movable piece 40, and meanwhile, the elastic sheet suddenly rebounds when the clamping relation between the elastic sheet and the movable piece 40 is released, so that impact prompt sound is generated, an operator can be reminded of wiring in place, the wiring accuracy is improved, and the problem that a circuit is not connected or has poor contact is effectively avoided.

To improve the reliability of the wiring, in this embodiment, the lock pin section 34 and the ejector section 33 may be disposed vertically, and referring to fig. 9, the clamping section 32 may bend the device in a direction approaching the ejector section 33. Therefore, the clamping state of the movable piece 40 and the clamping piece 30 is more stable, a larger clamping force is formed, and an impact prompt sound with proper size is formed.

Referring primarily to fig. 8 and 18, in some embodiments, the movable member 40 may be a button that is also used to switch the clamp member 30 from the clamped position to the open position upon manual depression. Thus, the position of the clamping member 30 can be adjusted manually, thereby further improving the convenience of wiring.

It should be noted that the following description will mainly describe specific structures of two kinds of buttons, and the movable member 40 of the electrical connector of the present utility model may only adopt the following button structures, and the structure of the movable member 40 or the button is controlled by setting a latch so that the clamping member 30 is kept at the open position, and the latch is pushed open by the wire 101 after the wire core of the wire 101 is inserted in place, so as to release the clamping state, and the structure of the clamping member 30 for clamping the wire 101 belongs to the technical scheme claimed by the present utility model.

After the core of the wire 101 is inserted in place, the wire 101 pushes up the latch section 34, the first latch slot 411 is disengaged from the latch section 34, and the clamp section 32 is switched to the clamp position to clamp the wire 101, thereby switching to the electrical connection state.

In this embodiment, the button may be in an arc shape and may be in an integrally formed structure, the insulating body 10 is provided with an arc-shaped groove connected with the mounting groove 10b, and the button is slidably disposed in the arc-shaped groove, and at this time, a avoidance bit 413 is formed between the two first pushing portions 412 of the button. Thus, the electric connector can be assembled conveniently, the button structure is relatively simple, and the production and manufacturing cost is low.

At the time of wire taking, the button is pressed so that the lock pin section 34 is engaged with the first lock pin slot 411 again, the wire is taken out, and the wire connection passage 10c is kept normally open again, waiting for the next wire connection.

It should be noted that the conductive body 20 and the clamping member 30 in this embodiment may have the same structure as the conductive body 20 and the clamping member 30 in the above embodiment, or may be slightly adapted, which is not limited herein.
