Description

Wire coupler {COUPLER FOR ELECTRIC WIRE}

The present invention relates to a wire coupler, and to a structure for improving contact efficiency between a terminal on the coupler side and an electric wire through a connection structure between the coupler and the electric wire and preventing the electric wire from being separated from the coupler.

In general, a plurality of wires are arranged on a distribution board requiring wiring work. Some of these wires are also connected to each other. A coupler is generally used for connection between wires, and coupling with a connection terminal is essential for a coupler connection between wires. The connection between these connecting terminals and wires is usually applied in a way that maintains the state while pressing the sheath, so the structure is relatively simple and it is difficult to improve the contact state. Accordingly, there is a demand for a coupler for configuring a distribution board capable of improving the contact state as well as the fixing force of the wires in connection between wires to the distribution board, thereby lowering resistance and further increasing power efficiency. In order to meet this demand, a method in which the electric wire is pressed from the outer circumferential surface and combined is sometimes employed, but the reality is that it is difficult to accommodate a structure in which two or more electric wires are arranged.

The converter may be formed along the first arrangement path 110 and the second arrangement path 120 formed in the second assembly 200 . That is, the connection terminals 300 and 300A may extend through the first arrangement path 110 and the second arrangement path 120 . Specifically, the connection terminals 300 and 300A may be extended through the first arrangement path 110 and the second arrangement path 120 . In addition, the connection terminals 300 and 300A are a pair, and include the first connection terminal 300 and the second connection terminal 300A, and in the second arrangement path 120 , the first connection terminal 300 and Although the second connection terminals 300A are arranged side by side, they may be alternately arranged in the first arrangement path 110 . This may be a structure in which the wires 10 and 20 are arranged in parallel to enable electrical connection.

In addition, the wires 10 and 20 include a first wire 10 and a second wire 20 that are electrically connected to each other through connection terminals 300 and 300A. Of course, more wires may be included through a modified implementation, but in the process of describing embodiments of the present invention, the connection between the first wire 10 and the second wire 20 will be described later as an example.

On the other hand, the connection terminal is composed of a pair (the first connection terminal 300 and the second connection terminal 300A) for connecting the first wire 10 and the second wire 20, each of the connection terminals is It includes a pair of terminals respectively connected to the conductive core 12 of the first wire 10 and the second wire 20 . That is, the connection terminal includes a first connection terminal 300 and a second connection terminal 300A, and the first connection terminal 300 is a 1-1 terminal 310 connected to the first wire 10, It may include a 1-2 terminal 320 connected to the second electric wire 20 and a first electric path 330 connecting the 1-1 terminal 310 and the 1-2 terminal 320 to each other. Of course, the second connection terminal 300A is also a second terminal 310A connected to the first wire 10, which is a configuration corresponding to the first connection terminal 300, and the second terminal connected to the second wire 20. It may include a second converter 330A connecting the 2-2 terminal 320A and the 2-1 terminal 310A to the 2-2 terminal 320A. As shown in FIG. 1 , the first wire 10 and the second wire 20 are each conductive core 12 to be connected with the corresponding first connection terminal 300 or the second connection terminal 300A. It may be separated in the process of being drawn into the second assembly 200 side.

The coupling between the first assembly 100 and the second assembly 200 may be made in a state in which the electric wire and the connection terminal are connected. The first assembly 100 may be coupled by a coupling between the second assembly 200 and the coupling protrusion 230 and the coupling hole 105 . The coupling protrusion 230 is formed on one side of the second assembly 200, and the coupling hole 105 is formed on one side of the first assembly 100, for example, the first assembly 100 and the second assembly ( 200) may be combined with each other by a process of elastic deformation and elastic restoration by being pressed in the opposite direction when provided with an insulating plastic material.

3 is a view showing a connection terminal to which an electric wire is connected and the second assembly 200 according to an embodiment of the present invention. Referring to FIG. 3 , the electric wire may be introduced in a direction in which the first arrangement path 110 and the second arrangement path 120 extend. In the case of the first wire 10, it can pass through the entire first array path 110, and in the case of the second wire 20, a part of the end portion overlaps one side of the second array path 120. can However, the arrangement method is not limited thereto, and may be changed according to the arrangement method of the first connection terminal 300 and the second connection terminal 300A.

As the first wire 10 and the second wire 20 are electrically connected to the connection terminals 300 and 300A, an electrical connection direction may be formed. One conductive core 12 included in the first wire 10 may be electrically connected to the 1-1 terminal 310 , and the 1-1 terminal 310 includes one conductive core 12 included in the second wire 20 . The conductive core 12 may be connected through the first and second terminals 320 and the first electric path 330 . Accordingly, the first wire 10 and the second wire 20 may be connected to electricity flowing through each conductive core 12 . The electrical connection direction by such electrical connection may be referred to as the first electrical connection direction W1. This means the flow on the illustrated first converter 330 and is not limited to one direction, but may be a bidirectional or selective determination according to the distribution structure.

In this way, the remaining conductive core 12 included in the first wire 10 may be electrically connected to the 2-1 terminal 310A, and the 2-1 terminal 310A includes the second wire 20 . A second terminal 320A connected to the remaining conductive core 12 may be connected through a second circuit 330A. Accordingly, electricity flowing through the conductive core 12 may be connected to the first wire 10 and the second wire 20 . Of course, it refers to the flow on the illustrated second circuit 330A, and is not limited to one direction, but may be a bidirectional or selective determination according to the distribution structure.

Furthermore, the first circuit 330 or the second circuit 330A may further include an insulating layer. As shown in FIG. 4 , the insulating layer IL may be formed on the first circuit 330 . 4 is a view showing the insulating layer (IL) formed on the connection terminal 300 according to an embodiment of the present invention, a point where the first electrical connection direction (W1) and the second electrical connection direction (W2) cross each other can be formed in Of course, the insulating layer (IL) in this example does not directly contact the conductor because the electrical transmission medium is different from each other in the structure of the example and the electric wire includes a covering, but may function as an auxiliary insulating means. As described above, since the insulating layer IL may be formed at a point where electrical connection directions intersect with each other, it is needless to say that the insulating layer IL is not limited to the position described with reference to FIG. 4 , the first circuit 330 .

5 is a perspective view of the second assembly 200 in which a pair of connection terminals are disposed according to another embodiment of the present invention. Referring to FIG. 5 , the second assembly 200 may further include a separation unit 240 .

The separation unit 240 performs a function of separating a pair of cores from the first wire 10 and the second wire 20 each including a pair of conductive cores. The wires 10 and 20 are connected to the connection terminals 300 and 300A, and at this time, one core and one terminal may be connected to each other. For such a connection configuration, an electric wire including a pair of conductive cores in one sheath may be divided into two so that each core is connected to a corresponding terminal.

Here, for separation, the second assembly 200 may include the separation unit 240 having a protruding structure. The separation unit 240 may separate the pair of cores on both sides of the edge through the protruding protruding edge, respectively, and the two separated coverings may be connected to corresponding terminals, respectively. Of course, this can be done in the process of being pressed toward the terminal.

For example, in the case of the second wire 20, a pair of conductive cores may be coupled to the first 1-2 terminal 320 and the second-2 terminal 320A, respectively. For the coupling, the electric wire may be pressed toward the terminal 1-2 and the terminal 2-2 320A, and the separation unit 240 may cut the coating during the pressing process. One side of the cut-out covering may be drawn into the 1-2 terminal 320 side, and the other side may be drawn into the 2-2 terminal 320A side. Here, the pressure may be directly transmitted by the user, or may be the pressure transmitted to the electric wire through the first assembly 100 by the user pressing the first assembly 100 .

A structure in which the wire is coupled to the terminal following the process in which the above-described wire is coupled to the connection terminal will be described in detail below. Accordingly, it is assumed that the pair of conductive cores 12 included in the electric wires 10 and 20 are in a spaced apart state while the covering 11 is separated. The coupling between the wires 10 and 20 and the terminals 310, 320, 310A, and 320A is, in this embodiment, the coupling of the first wire 10 and the 1-1 terminal 310, the first wire 10 and the second The coupling of the 2-1 terminal 310A, the coupling of the second wire 20 and the 1-2 terminal 320, and the coupling of the second wire 20 and the 2-2 terminal 320A are made. Among them, the coupling between the first wire 10 and the 1-1 terminal 310 will be described later as an example, and the coupling structure described later is the 1-2 terminal 320 and the 2-1 terminal 310A. ) and the second-2 may be applied to the terminal 320A, of course, and each embodiment may be selectively implemented simultaneously if there is no structural interference.

6 is a view showing that the first terminal 310 is connected to the first wire 10 according to the first embodiment of the present invention. Referring to FIG. 6 , the first wire 10 includes a core 12 composed of a plurality of thin wires 13 . The core 12 may be located inside the sheath 11 . The sheath 11 may be provided in one or more layers, and performs one or more functions of insulation and cushioning. In addition, the covering 11 may be a material having predetermined elasticity and ductility. For example, it may be a material containing a rubber material. Therefore, by the covering 11, the electric wire is flexible by ductility, and elastic recovery may be possible after deformation by elasticity.

Here, as the first wire 10 is inserted into the 1-1 terminal 310 , the core 12 may come into contact with the contact portion 321 of the 1-1 terminal 310 . The width of the terminal 1-1 (310) is formed to be narrower than the diameter of the first wire (10). Due to the difference in diameter and width, the electric wire is pressed from the 1-1 terminal 310 so that the fixing force for fixing the first electric wire 10 can be further increased.

Meanwhile, when the first wire 10 is inserted, a portion of the covering 11 may be cut by the pre-cut portion 311 provided in the 1-1 terminal 310 . This increases the fixing force in the longitudinal direction of the first electric wire 10 while cutting a part of the covering 11 , and can facilitate the insertion in the pressing direction P when the first electric wire 10 is inserted.

Furthermore, the 1-1 terminal 310 may include a fixing part 315 protruding from the side in the pressing direction P toward the covering 11 of the first electric wire 10 to be inserted. Specifically, a plurality of fixing parts 315 protruding toward the upper right or upper left based on the drawing shown from the side may be formed, respectively. The protruding end of the fixing part 315 may be formed in a tip shape. This allows the fixing portion 315 to be more efficiently inserted into the covering 11 when the first wire 10 is inserted in the pressing direction (P).

The protrusion shape of the fixing part 315 is not fixed toward the upper right or upper left, and after the first wire 10 is inserted into the covering 11 while being inserted in the pressing direction (P), the pressing direction ( P), it can be deformed to the lower left and lower right until the time when the pressurization is completed. This may be a structure for preventing the electric wire from being separated in the direction opposite to the pressing direction (P) of the fixed portion 315 deformed to the lower left or lower right.

At this time, the covering 11 may be in a somewhat elastically deformed state by pressing in the pressing direction (P). The elastic deformation may cause a change in the cross-sectional shape of the core 12 located inside the sheath 11 . In the present embodiment, during insertion in the pressing direction P, the contact portion 321 and the covering 11 are in contact from below, and a deformation that is elongated in the horizontal direction may occur. This shape may be the elastic deformation, and the core 12 may be in contact with the fixing part 315 of the side surface by the elastic deformation. At least the thin wires 13 may come into contact. In addition, the coating 11 may be penetrated by the contact portion 321 positioned below to make contact between the core 12 and the contact portion 321 . The first wire 10 and the 1-1 terminal 310 may be electrically connected by such a contact.

This electrical contact can be pressed in the pressing direction P so that the contact surface 321a between the contact portion 321 and the core 12 is formed wider in order to reach an improved condition (increased contact area) for reducing the electrical resistance. have. As a method for satisfying the improved condition, there is a method in which an area exposed upward from the contact portion 321 is formed to be wide or a pressing force in the pressing direction P is made stronger.

Structural modification may be implemented as a means for satisfying the improved condition. 7 is a view illustrating that a terminal according to a second embodiment of the present invention is connected to an electric wire. Referring to FIG. 7 , it may be assumed that the core 12 is formed of a plurality of thin wires 13 . The first wire 10 is pressed in the pressing direction P, and a portion of the covering 11 may be cut by the pre-cut portion 311 . The cut coating 11 may promote movement of the first wire 10 in the pressing direction (P).

The first wire 10 pressed in the pressing direction P may reach a plurality of contact portions 331 with tips exposed upward, located below the 1-1 terminal 310 . In the contact portion 331 including a plurality of tips, the coating 11 of the first electric wire 10 is penetrated by the tips, so that contact with the thin wire 13 may occur. Due to the shape of the contact portion 331 including a plurality of tips, the contact surface 331a between the contact portion 331 and the thin wire 13 may be formed on an inclined surface connecting the attachment and the valley portion.

The plurality of thin wires 13 are preferentially accommodated on the trough side of the central portion relatively along the contact surface 331a, and the plurality of thin wires 13 may be sequentially accommodated toward the trough side located on the side by pressing. An example of the thin wire 13 accommodated in the valley side is shown in FIG. 7 . Further, the plurality of tips may have different upwardly extending lengths.

That is, a length difference D1 may be formed between the contact portions 332 . For example, as the distance from the central portion to the side increases, the contact portion 331 may extend upwardly longer. This may be a structure that induces the contact of the thin wire 13 in the terminal 1-1 310 to be made on the contact surface 331a formed as an inclined surface.

Specifically, when the contact surface 331a of the same height is exposed in the vertical direction, the contact surface 331a being formed as an inclined surface may be a structure that can form the contact surface 331a wider than when the contact surface 331a is vertical. By application of this structure, the thin wire 13 is preferentially contacted from the central portion, and a structure inducing the thin wire 13 to be accommodated in the valley side located on the side may be formed. Through this, the thin wire 13 can make contact with the wider contact surface 331a by avoiding contact with the vertical surface of the terminal 1-1 310 located on the outermost side.

Accordingly, the storage capacity that can be accommodated in the valley side may correspond to the volume of the thin wire 13 . That is, when the diameters of the thin wires 13 are the same, conditions such as the height at which the angle of the inclined surface is extended upward may vary according to the number of the thin wires 13 . For example, since the capacity of the thin wire 13 is different between 30 and 50 thin wires 13, the conditions for determining the capacity may be changed.

8 is a view illustrating that a terminal according to a third embodiment of the present invention is connected to an electric wire. 8 shows a cross-section of the contact portion 341 including one leading end portion and two receiving portions 342, and the receiving portions 342 are to be located on both sides from the fore end portion 341b, respectively. can Here, the proximal end portion 341b and the receiving portion 342 may extend by a predetermined length along the first arrangement path 110 . For example, the terminal 1 - 1 310 may extend as much as a width formed in the direction of the first array path 110 .

On the other hand, the first wire 10 moved by the pressing in the pressing direction (P) may reach the leading end (341b) of the contact portion (341). The proximal end portion 341b may be in contact with the thin wire 13 through the sheath 11 . At this time, the first wire 10 that is continuously pressed causes the covering 11 to move toward the receiving part 342 . The thin wires 13 that are moved downward by the pressing force following the covering 11 may be moved toward the receiving portion 342 located on the left and right with respect to the centrally located fore end 341b.

When a part of the outer peripheral surface of the covering 11 is cut by the pre-incision part 311 and then pressed in the pressing direction P to reach the contact part 341, it spreads laterally based on the contact point, but a plurality of thin wires 13 ) is composed of each thin wire 13 which is an independent entity smaller than the cross-sectional area of the accommodating part 342 , so that each thin wire 13 can maintain a state accommodated in the accommodating part 342 . As described above, as the contact portion 341 extends along the first array path 110 , the contact area of the contact surface 341a may be increased. It can be employed as a structure to reduce resistance in the process of electric transmission. Since a part of the first wire 10 is illustrated, it is of course possible to have the same structure on the second wire 20 side.

9 is a view showing that a terminal according to a fourth embodiment of the present invention is connected to an electric wire. Referring to FIG. 9 , the contact part 351 may include a tip part 351b , a guide part 352 , and a receiving part 351a . Here, the receiving portion 351a may be a space in which the thin wire 13 is accommodated and the contact surface 351a to which the thin wire 13 is in contact faces each other.

Specifically, when the first wire 10 is pressed in the pressing direction (P), the coating 11 reaches the tip portion (351b). The sheath 11 may be cut by the tip 351b. The tip portion 351b is located in the center of the terminal 1-1 310, and the covering 11 cut by the tip portion 351b may be moved by being pushed to both sides. The direction in which the cut side of the covering 11 is moved may be lower left and lower right, which are both sides based on the tip portion 351b. The covering 11 moving to both sides may be moved according to the pressure by the guide part 352 guiding it along the extension lines of the lower left and lower right.

At this time, the thin wire 13 moving in the pressing direction P on the covering 11 is divided by the tip portion 351b on both sides of the movement line, and the process of moving on the extension line of the lower left and lower right in both directions. It may be introduced into the receiving portion 353 in the. The width of the receiving portion 351a formed in the contact portion 351 in a direction parallel to the pressing direction P on the extension line may be determined in a range of 1.5 to 3 times the diameter of the thin wire 13 . The determination of such a width range may have a structure for inducing the inflow of the thin wire 13 but blocking the inflow of the covering 11 .

In addition, the guide part 352 is provided with an inclined surface on the extension line for guiding the thin wire 13 to the receiving part 351a. The inclined surface may be provided with an inclined surface inclined to the lower left on an extension line of the lower right side, and an inclined surface inclined downward to the right on the extension line of the lower left side may be provided. The thin wire 13 moving on the extension line by the inclined surface may be introduced into the accommodating part 353 . Ideally, in the case of the core 12 including 30 thin wires 13, the receiving portion 351a includes three on the lower left side and three on the lower right side with respect to the tip portion 351b. When five thin wires 13 are accommodated in each of the receiving portions 351a of , all 30 thin wires 13 are accommodated, so that the 1-1 terminal 310 and all the thin wires 13 can come into contact with each other. Of course, this is only an ideal example and is not limited thereto, and the accommodating space of the accommodating part 351a may be sufficiently secured. That is, the contact portion 351 may be provided so that its capacity exceeds that of the thin wire 13 .

FIG. 10 is a view showing that the fixing part 315 according to the fifth embodiment of the present invention is connected to the electric wire, and FIG. 11 is a view showing the fixing part 315 according to the sixth embodiment of the present invention. 11A in FIG. 11 is a view showing the fixing part 315 from a perspective side, and FIG. 11B is a view showing the fixing part 315 from the front. 10 to 11 , the fixing part 315 may be positioned on a path along which the first electric wire 10 moves in the pressing direction P.

Specifically, the fixing part 315 may include a cutout 325a, an extended part 325b, a separation preventing part 325c, and a receiving part 325d. First, the first wire 10 may be pre-pressurized in the lateral direction by the guide 311a while moving in the pressing direction. The cutout 325a is configured to non-penetrate a portion of the surface of the covering 11 while the first wire 10 is moved in the pressing direction (P) of the first wire 10 . The expanded part 325b spreads the cut-out line 11a formed in the process of moving the cut-out covering 11 in the pressing direction P to both sides based on the cut-out 325a to move in the pressing direction P. is a configuration that When a force is applied in the departure direction (B) through the first wire (10), the separation prevention unit (325c) is configured to generate a reaction in the pressing direction (P) to prevent separation.
