Referring to FIGS. 1 to 5 , it is the first embodiment of the present invention. The embodiment provides a wire butting connector suitable for teaching, which includes a first butt-jointing module 100 and a second butt-jointing module 200 . External wires can be connected respectively, and the inner ends of the two can also be connected to each other to realize the connection of the two wires.

Specifically, the first docking module 100 includes a first head part 101 and a first tail part 102 , which can be detachably connected, so that the first docking module 100 can be easily disassembled to connect wires. Specifically, the connection between the first head 101 and the first tail 102 may be realized by means of screw connection, snap connection or other detachable connection. The inner end of the first tail portion 102 is open and connected to the first head portion 101 . The outer end of the first tail portion 102 has an outer end surface, and the outer end surface is provided with a threading hole.

The first docking module 100 further includes a first conductive column 103 , one end (inner end) of the first conductive column 103 is fixed in the first head 101 , and the other end (outer end) extends out of the first head 101 . When installing the wire, first disassemble the first head 101 and the first tail 102, then peel off the end of the wire to be connected to expose the wire core, and then pass the exposed end of the wire core through the threading hole of the first tail 102 , and connect with the inner end of the first conductive column 103 (the connection here can be solder or other existing wire connection methods), and finally connect the first head 101 and the first tail 102 again to form an external protection.

The second docking module 200 is another module that can be connected with the first docking module 100, and includes a second head 201 and a second tail 202, which can also be detachably connected. Preferably, both The connection method is the same as that of the first docking module 100 . The inner end of the second tail portion 202 is open and connected to the second head portion 201 . The outer end of the second tail portion 202 has an outer end surface, and the outer end surface is provided with a threading hole.

The second docking module 200 further includes a second conductive column 203 , and the second conductive column 203 is disposed inside the second tail portion 202 . When installing the wire, first disassemble the second head 201 and the second tail 202, then peel the end of the other wire to be connected to expose the wire core, and then pass the exposed end of the wire core through the second tail 202. Thread the hole and connect it with the inner end of the second conductive column 203 (the connection here can use solder or other existing wire connection methods), and finally connect the second head 201 and the second tail 202 again to form an external protection.

In the present invention, the first head part 101 of the first docking module 100 can be connected with the second head part 201 of the second docking module 200 (can be achieved by snap connection or other detachable methods, but cannot Amplitude rotation connection, such as screw connection), when the first head 101 and the second head 201 are connected, the first conductive column 103 can enter the second docking module 200 and connect with the second conductive column 203. , so as to realize the connection of the circuits respectively connected to the first docking module 100 and the second docking module 200 .

The first head 101 and the first tail 102 and the second head 201 and the second tail 202 in the above are detachably connected protective shells, which are made of insulating materials, such as plastic; the first conductive pillars 103 and the second The conductive pillars 203 are pillar-shaped conductive structures made of hard conductive materials, such as copper. In practice, there are generally three parallel and isolated wires, namely the live wire (L), the neutral wire (N) and the ground wire (E), so the first conductive column 103 and the second conductive column in the present invention are 203 also has three parallel, parallel and non-contact with each other, and is connected in series with the corresponding three wires (L, N, E). Each of the first conductive pillars 103 can also be docked with the corresponding second conductive pillars 203 to achieve one-to-one correspondence.

Further, the outer end of the second conductive column 203 is recessed with a slot 203a. When the first head 101 and the second head 201 are connected, the outer end of the first conductive column 103 can be inserted into the slot 203a, so that the The first conductive pillars 103 can be better docked with the second conductive pillars 203 .

Further, the connection between the first header 101 and the second header 201 may be as follows:

Two ends of the first head 101 are a plug end 101a and a first connection end 101b respectively. The outer diameter of the first connection end 101b is larger than that of the plug end 101a, and a stepped surface 101c is formed at the joint of the two. At least two protrusions 101a-1 are distributed on the outer side wall of the plug end 101a (one circle along the lateral direction). When the first connection end 101b and the first tail portion 102 are connected by screw threads, the inner side wall of the first connection end 101b has an inner thread, and the outer side wall of the inner end of the first tail portion 102 has an outer thread matched with the inner thread.

The main body of the second head 201 is in the shape of a hollow sleeve, two ends of which are an open end 201a and a second connecting end 201b respectively. When the second connection end 201b and the second tail portion 202 are connected by screw threads, the inner side wall of the second connection end 201b has an inner thread, and the outer side wall of the inner end of the second tail portion 202 has an outer thread matched with the inner thread.

The inner edge of the opening of the open end 201a has a limit ring 201c that fits with the outer diameter of the plug-in end 101a. The limit ring 201c has a notch 201c-1 that fits with the protrusion 101a-1. Therefore, if the protrusion 101a-1 is aligned with the notch 201c-1, then the first head 101 can be inserted into the accommodating space 201a-1 of the open end 201a, so that the inner ring surface of the limiting ring 201c is just fit on the accommodating space 201a-1. On the outer side wall of the first head 101, the protrusion 101a-1 can pass through the notch 201c-1. If the first head 101 is rotated, the protrusion 101a-1 can be misaligned with the notch 201c-1, so that the first head 101 cannot be detached from the accommodating space 201a-1, and the first head 101 and the second head can be realized Detachable connection between parts 201. Since the rotation of the first head 101 can drive the eccentric first conductive pillars 103 to rotate as a whole, the first conductive pillars 103 also drive the corresponding second conductive pillars 203 to rotate as a whole. Even if the second conductive column 203 has been connected to a wire, since the wire itself has a certain degree of flexibility and can undergo a certain degree of torsional deformation, the connection between the first head 101 and the second head 201 is not hindered.

Further, in order to further optimize the connection between the first head 101 and the second head 201 and make it more stable, the present invention sets: the inner side of the limit ring 201c has a container that fits with the protrusion 101a-1. There is a certain dislocation angle between the accommodating groove 201c-2 and the notch 201c-1. The concept of "dislocation angle" here is: the vertical line from the center of the accommodating groove 201c-2 to the axis of the limit ring 201c is the first side, and the vertical line from the center of the notch 201c-1 to the axis of the limit ring 201c is the second side side, the angle between the first side and the second side on the lateral projection is a misalignment angle, so when the first head 101 is inserted into the accommodating space 201a-1 and rotated, the protrusion 101a-1 can be embedded in the accommodating groove 201c -2 within. At the same time, the slot 203a is an arc-shaped track, and the central angle of the arc is the same as the misalignment angle. When the protrusion 101a-1 is rotated and embedded in the accommodating groove 201c-2, the outer end of the first conductive column 103 can be Corresponding displacement occurs along the arc track in the slot 203a, and moves to the other end of the slot 203a. In this way, when the first conductive column 103 rotates, its influence on the second conductive column 203 can be reduced.

Further, in order to make the tight connection between the first conductive column 103 and the second conductive column 203 to prevent loosening, and to ensure the safe passage of the circuit, the present invention also includes the following technical solutions:

The second docking module 200 further includes a pressing component 204 for pushing the second conductive column 203 to press the first conductive column 103 tightly. The extrusion assembly 204 includes a binding member 204a and an elastic member 204b. The binding member 204a is fixed with each second conductive column 203, and each second conductive column 203 is "bundled" into a whole bundle that is parallel to each other and does not contact each other; the elastic member 204b adopts a compression spring, one end of which is pressed against the The inside of the two tails 202, the other end abuts on the binding member 204a, and can push the binding member 204a and the second conductive column 203 connected thereto as a whole, so that the second conductive column 203 and the first conductive column 103 are tightly pressed .

Specifically, the binding member 204a includes a connecting column 204a-1 fixed with each of the second conductive columns 203 and a ring of outer edge rings 204a-2 fixed on the outer sidewall of the connecting column 204a-1. The connection post 204a-1 is a cylindrical structure with an opening, and the “hole” here is the second fixing hole K-2 corresponding to the second conductive post 203, which is matched with the channel of the cross section of the second conductive post 203. The two conductive pillars 203 are inserted and fixed in the corresponding second fixing holes K-2. The connection posts 204a-1 are made of insulating material (eg, plastic), which ensures that the second conductive posts 203 are isolated from each other and prevents short circuits. The outer edge ring 204a-2 is a transverse annular structure on the outer side wall of the connecting column 204a-1, and the elastic member 204b is sleeved on the periphery of the connecting column 204a-1, one end of which is pressed against the inside of the second tail portion 202, and the other end is pressed against the outer edge ring On 204a-2, a thrust can be generated on the outer edge ring 204a-2.

In addition, the inner side wall of the second head 201 also has a ring-shaped blocking ring 201d, the inner diameter of which is smaller than the outer diameter of the outer edge ring 204a-2 and larger than the outer diameter of the connecting post 204a-1, when the second head 201 When connecting with the second tail portion 202, the blocking ring 201d can squeeze the outer edge ring 204a-2 and limit it, so that the entire pressing component 204 is squeezed and received inside the second tail portion 202 to complete the second tail portion 202. Assembly of the docking module 200 as a whole. Therefore, after the second docking module 200 is assembled, the elastic member 204b is pressed or compressed to a certain extent. When the first head 101 and the second head 201 are connected (ie, the protrusion 101a-1 is embedded in the accommodating groove 201c-2), the first conductive column 103 bears against the second conductive column 203, and makes the outer edge ring 204a-2 is disengaged from the blocking ring 201d, which ensures the tight butt joint between the first conductive post 103 and the second conductive post 203 .

The inner sidewall of the second tail portion 202 is divided into a first section 202a and a second section 202b with different inner diameters, the second section 202b corresponds to the opening of the outer end of the second tail section 202, and the first section 202a corresponds to the inner end . The inner diameter of the second section 202b is larger than the inner diameter of the first section 202a, forming a step shape, one end of the elastic member 204b abuts on the step, and the other end abuts on the outer edge ring 204a-2.

Further, in order to facilitate the storage of the extrusion assembly 204 and facilitate the overall assembly of the second docking module 200, a guide sleeve 204a-3 is fixed on the outer edge of the outer edge ring 204a-2. Specifically, the guide sleeve 204a-3 is a sleeve-like structure fitted with the inner diameter of the second section 202b, one end of which is fixed on the outer edge of the outer edge ring 204a-2, and the other end faces the direction of the first section 202a. In addition, the outer sidewall of the connecting post 204a-1 is fitted with the outer sidewall of the first section 202a. Therefore, the entire extrusion assembly 204 and the second conductive column 203 can perform longitudinal linear movement together.

Further, in the present invention, the fixing method of the first conductive column 103 in the first head 101 is as follows:

The interior of the first head 101 has a longitudinal accommodating channel 101 d , one end of the first conductive column 103 is fixed in the accommodating channel 101 d , and the other end extends out of the first head 101 . Specifically, the accommodating channel 101d is fixed with a fixing piece 101e (it can also be an integral structure), and the fixing piece 101e has a first fixing hole K-1 matched with the first conductive pillars 103, and each of the first conductive pillars 103 is inserted through and fixed in the corresponding first fixing hole K-1. Therefore, the fixing sheet 101e can "bundle" each of the first conductive pillars 103 into a whole bundle that is parallel to each other and not in contact with each other. The fixing piece 101e is made of insulating material (eg, plastic) to ensure that the first conductive pillars 103 are isolated from each other.

Further, the insides of the first tail portion 102 and the second tail portion 202 respectively have a first chamber 102a and a second chamber 202c. The connection points of the first conductive pillars 103 and the second conductive pillars 203 and the wires are located in the respective first chamber 102a or the second chamber 202c. The outer ends of the first tail portion 102 and the second tail portion 202 are respectively fixed with a first protective cover 104 and a second protective cover 205, which are used to ensure waterproof and anti-breakage at the threading hole. The first protective cover 104 and the second protective cover 205 has a channel corresponding to the threading hole.

The three wires (L, N, E) of the plug-in wire are wrapped with an insulating layer except for the exposed wire core at the connected ends. Finally, the three wires with the insulating layer are uniformly bundled into a whole wire bundle through the insulating wire sheath. Plug-in wires.
