Description
본 발명은 전원 플러그에 관한 것으로, 전원 플러그의 도전단자에 전선을 연결함에 있어서, 별도의 고정수단의 구성없이 전선을 고정시킬 수 있도록 하는 플러그의 전선 접속 고정구조에 관한 것이다.The present invention relates to a power plug, and more particularly, to a wire connection fixing structure of a plug that enables a wire to be fixed without a separate fixing means in connecting a wire to a conductive terminal of the power plug.
일반적으로 플러그는 콘센트에 끼워 접속되는 도전봉과, 도전봉과 일체형의통전구조를 갖는 전선접속단자와, 케이스로 구성을 나눌 수 있다.In general, the plug can be divided into a conductive rod connected to an outlet, a wire connecting terminal having a conductive structure integral with the conductive rod, and a case.
케이스내에는 피복이 벗겨진 도선 부위가 전선접속단자에 접속 고정된 전기적 연결구조를 갖는다.In the case, the stripped conductor part has an electrical connection structure in which the wire connection terminal is connected and fixed.
이와 같은 전원 플러그는 전선의 피복을 벗긴 후, 피복이 벗겨진 도선 부위를 전선접속단자에 고정시키고, 전선이 결합된 전선접속단자를 케이싱 작업을 진행하여 작업 완료한다.The power plug is stripped of the wire, and then the stripped wire part is fixed to the wire connection terminal, and the wire connection terminal to which the wire is coupled is processed by completing the casing.
일반적으로 전자기기에 이용되는 전원 플러그의 경우에는 생산공정상에서 케이싱작업은 금형내에 상기와 같은 도전봉의 일부와 전선접속단자를 고정시키고 PVC 수지를 주입하여 케이싱 작업을 완료한다.In general, in the case of a power plug used in an electronic device, a casing operation in a production process fixes a part of the conductive rod and a wire connection terminal in a mold and injects PVC resin to complete the casing operation.
상기에서와 같이 케이스를 이용하는 경우에는 전선접속단자에 나사공을 형성하고, 나사에 도선을 감아 나사공에 결합 고정시키거나, 전선접속단자와 도선의 연결부위에 납땜을 하여 고정시키는 방법을 이용한다.In the case of using the case as described above, a screw hole is formed in the wire connection terminal, and a wire is wound around the screw to fix and fix the screw hole, or soldering is fixed to the connection portion between the wire connection terminal and the wire.
또한 상기의 다른 경우예에서와 같이 PVC 수지에 의해 케이싱을 수행하는 경우에는 굳이 전선접속단자에 전선을 고정시키지 않고, 전선접속단자에 도선을 위치시킨 후 금형내에서 PVC 수지에 의한 몰딩을 진행한다.In addition, when casing is made of PVC resin as in the other case, the wire is not fixed to the wire connection terminal, but after the conductor is placed on the wire connection terminal, molding is performed by PVC resin in the mold. .
이와 같이 전원 플러그의 생산공정상에서 전선접속단자에 전선을 접속고정시킴에 있어, 나사와 같은 별도의 고정수단을 필요로 하며, 또한 작업자로 하여금 고정수단을 이용하여 체결고정시켜야 하는 불편함이 뒤따르게 됨은 물론, 전선에 장력이 작용할 경우 전선이 고정수단으로부터 풀려 단락이 발생할 수 있는 문제점이뒤따르게 된다.As described above, in fixing the electric wires to the wire connecting terminals in the production process of the power plug, a separate fixing means such as a screw is required, and the inconvenience that the worker must fasten and fasten using the fixing means follows. Of course, when the tension is applied to the wire is a problem that the wire is released from the fixing means may cause a short circuit.
또한, 납땜의 경우 고정이 확실한데 반해, 납땜공정을 수행하여야 하는 불편함이 있다.In addition, in the case of soldering is fixed, while the soldering process has to be inconvenient.
또한, PVC 수지에 의한 케이싱 작업에 있어서도 작업자가 전선의 그 위치를 잡아 고정시켜야 하므로, 작업에 어려움이 있다.In addition, even in the casing operation by the PVC resin, the operator has to hold the position of the electric wire to fix it, there is a difficulty in the operation.
이와 같이 종래 플러그의 전선 접속 고정에 따르면 작업에 대량생산에 어려움이 있다.As described above, according to the conventional wire connection fixing of the plug, there is a difficulty in mass production.
본 발명은 전선을 접속 고정시킴에 있어, 전선이 고정되는 접속고정단자의 전선결합단에 도선이 삽입될 수 있도록 삽입공을 형성하고, 도선삽입후 삽입공이 형성된 전선결합단의 외부로부터 소정의 압력을 가해 압착시켜 전선결합단이 눌려지면서 삽입공내의 도선이 전선결합단에 접속된상태를 유지하면서 삽입공내에서 고정될 수 있도록 하므로써, 그 공정을 간단히 하면서도, 효과적인 접속구조를 제공하는 플러그의 전선 접속 고정 구조에 관한 것이다.In the present invention, in the connection fixing of the wire, the insertion hole is formed so that the conductor can be inserted into the wire coupling end of the connection fixing terminal to which the wire is fixed, and the predetermined pressure from the outside of the wire coupling end formed with the insertion hole after the wire insertion The wire connection of the plug, which simplifies the process and provides an effective connection structure, is made by pressing the wire coupling end so that the wire in the insertion hole can be fixed in the insertion hole while maintaining the state connected to the wire coupling end. It relates to a fixed structure.

본 발명은 콘센트에 끼워지는 도전봉과, 도전봉과 일체형으로 통전구조를 갖는 전선접속단자를 포함하여 전기적 접속을 제공하는 전원플러그에 있어서,The present invention provides a power plug including an electrically conductive rod inserted into an outlet, and a wire connection terminal having an electrically conductive structure integrally with the electrically conductive rod.
상기 전선접속단자는 도선이 삽입될 수 있도록 도선삽입공이 형성된 전선접속 결합부를 포함하여 구성되고, 전선접속결합부는 도선삽입공내에 도선이 삽입된 상태에서 가압장치에 의해 압착되어 도선삽입공내의 도선을 고정시키도록 한 구조를 갖는 것을 특징으로 한다.The wire connection terminal includes a wire connection coupling portion formed with a wire insertion hole so that the wire can be inserted, and the wire connection coupling portion is crimped by a pressing device in a state where the wire is inserted into the wire insertion hole to press the wire in the wire insertion hole. It is characterized by having a structure to be fixed.
상기 전선접속결합부에 압착공정시 균열이 발생하게됨을 방지하기 위하여 가압장치에 의해 형성되는 압착면은 다각면으로 형성되는 것을 특징으로 한다.In order to prevent cracks from occurring during the crimping process of the wire connection coupling part, the crimping surface formed by the pressing device is formed in a polygonal surface.
이와 같은 특징을 갖는 본 발명 전원 플러그의 전선 접속 고정 구조를 첨부된 도면 도 1 내지 도 4에 도시된 실시예를 참조하여 그 구성 및 작용을 설명하면 다음과 같다.Referring to the embodiment shown in Figures 1 to 4 attached to the wire connection fixing structure of the power plug of the present invention having such a feature will be described as follows.
콘센트에 끼워지는 도전봉(10)과, 도전봉(10)과 일체로 형성되어 통전구조를 갖으며, 전선(20)의 피복이 벗겨진 도선(21)이 접속고정되는 전선결합부(31)를 포함하는 전선접속단자(30)와, 도전봉(10)과 전선접속단자(30)에 PVC수지로 1차 몰딩된 1차 케이스(40)와, 도선(21) 접속고정후 전선결합부(31)의 외부 접촉을 방지하기 위하여 1차 케이스(40)에 결합되는 2차 케이스(50)를 포함하여 구성되며,The wire connecting portion 31 is formed integrally with the conductive rod 10 to be inserted into the outlet, and has a current-carrying structure, and is connected to and fixed to the conductive wire 21 having the wire 20 peeled off. The wire connecting terminal 30, the conductive rod 10 and the wire connecting terminal 30, the primary case 40 first molded with PVC resin, and the wire 21 after fixing the connection of the wire coupling portion 31 Including a secondary case 50 coupled to the primary case 40 to prevent external contact of
상기 전선결합부(31)는 도선(21)이 삽입될 수 있도록 도선삽입공(31a)이 형성되며, 도선삽입공(31a)내로 도선(21)이 삽입된 상태에서 외부의 가압장치에 의해 압착되어 도선(21)을 도선삽입공(31a)내에 고정시키는 구조를 갖는다.The wire coupling portion 31 has a conductive wire insertion hole 31a formed to allow the conductive wire 21 to be inserted therein, and is crimped by an external pressurizing device in a state in which the conductive wire 21 is inserted into the conductive wire insertion hole 31a. To fix the conductive wire 21 in the conductive wire insertion hole 31a.
압착공정시 상기 전선결합부(31) 외주면에 형성되는 압착부(32a)는 육각면을 갖도록 형성된다.During the crimping process, the crimping portion 32a formed on the outer circumferential surface of the wire coupling portion 31 is formed to have a hexagonal surface.
이와 같은 구조를 갖는 본 발명 전원 플러그의 전선(20) 접속 고정 구조의 실시예는 PVC수지를 이용하여 도전봉(10)과 전선(20)접속단자를 몰딩하여 케이싱한 구조를 갖으며, 이와 같은 1차 케이스(40)에 2차 케이스(50)를 결합시켜 전원 플러그를 구성한 일 실시예를 보인 것으로, 이에 제한적이지 않고, 전체 몰딩 또는 전체를 케이스를 이용하여 케이싱하는 다양한 구조가 적용 가능하다.The embodiment of the wire 20 connection fixing structure of the power plug of the present invention having such a structure has a structure in which the conductive rod 10 and the wire 20 connecting terminal is molded by using a PVC resin, such as casing, One embodiment in which a power plug is configured by coupling the second case 50 to the first case 40 is not limited thereto. Various structures for casing the entire molding or the whole using the case may be applied.
본 실시예에 있어서는, 도전봉(10), 전선접속단자(30)가 PVC수지에 의해 몰딩되어 1차 케이스(40)가 구성된다.In this embodiment, the conductive rod 10 and the wire connection terminal 30 are molded by PVC resin to form the primary case 40.
이때, 전선접속단자(30)의 전선결합부(31)는 1차 케이스(40)의 외부로 나타나도록 구성되어 있다.At this time, the wire coupling portion 31 of the wire connection terminal 30 is configured to appear to the outside of the primary case (40).
이와 같은 전선(20)이 접속 고정되는 전선접속단자(30)의 전선(20)결합부(31)에 전선(20)이 끼워지는 방향으로 도선삽입공(31a)을 형성시켜 도선(21)이 도선삽입공(31a)내로 삽입될 수 있도록 하는 구조를 갖는다.The conductive wire insertion hole 31a is formed in the direction in which the electric wire 20 is fitted into the electric wire 20 coupling portion 31 of the electric wire connection terminal 30 to which the electric wire 20 is connected and fixed. It has a structure that can be inserted into the lead insertion hole (31a).
상기 도선삽입공(31a)의 내경은 도선(21)이 원활하게 끼워질 수 있으며, 압착시 도선(21)과 접속이 이루어지면서 균열이 발생하지 않도록 그 크기가 결정된다.The inner diameter of the conductive wire insertion hole 31a may be smoothly fitted to the conductive wire 21, and the size of the conductive wire insertion hole 31a may be smoothly inserted so that cracks do not occur when the conductive wire 21 is connected to the conductive wire 21.
즉, 도 3b에서와 같이, 도선삽입공(31a)의 내경이 크게 되면, 도선삽입공(31a)에 의해 전선결합부(31)의 압착력을 받게되는 두께(d1)가 얇아지게 되므로, 압착공정시 파손될 염려가 있으므로, 이를 방지하기 위한 것이다.That is, as shown in Figure 3b, when the inner diameter of the lead wire insertion hole (31a) is large, the thickness (d1) that is subjected to the pressing force of the wire coupling portion 31 by the lead wire insertion hole 31a becomes thin, the pressing process Since there is a risk of breakage, it is to prevent this.
또한, 도 3a에서와 같이, 도선삽입공(31a)의 깊이 즉, 길이(d2)는 도선(21)의 접속부분을 고려하여 설정하고, 도선삽입공(31a)의 길이(d2)에 따라 압착부(32a)는 도선삽입공(31a)의 입구 즉, 전선결합부(31)의 선단에 가까울수록 압착공정시 전선결합부(31)가 손상(균열, 갈라짐, 파손)이 발생될 수 있기 때문에 도선삽입공(31a)의 길이(d2)에 대하여 이분할된 중앙의 위치 또는 중앙의 위치로부터 선단방향으로 형성하는 것이 적정하다.3A, the depth of the lead insertion hole 31a, that is, the length d2 is set in consideration of the connecting portion of the lead wire 21, and is crimped according to the length d2 of the lead insertion hole 31a. Since the portion 32a is closer to the inlet of the wire insertion hole 31a, that is, the tip of the wire coupling portion 31, the wire coupling portion 31 may be damaged (crack, crack, break) during the crimping process. It is appropriate to form in the tip direction from the center position or the center position divided into two with respect to the length d2 of the lead insertion hole 31a.
또한, 도 3c에서와 같이, 압착공정시 전선결합부(31)의 균열을 방지하기 위하여 상기 전선결합부(31)의 외주면에 형성되는 압착부(32a)는 육각면이 형성될 수 있도록 하는 바,In addition, as shown in FIG. 3c, in order to prevent cracking of the wire coupling part 31 during the crimping process, the pressing part 32a formed on the outer circumferential surface of the wire coupling part 31 may have a hexagonal surface. ,
가압장치에 의해 전선결합부(31)의 외주면에 일정하게 압력이 가해질 수 있도록 하므로써, 전선결합부(31)의 균열을 방지하도록 하는 것이다.The pressure is applied to the outer circumferential surface of the wire coupling portion 31 by a pressure device so as to prevent cracking of the wire coupling portion 31.
이는 전원 플러그의 전선접속단자(30)는 일반적으로 도전성 대비 생산비용을 고려하여 황동을 사용하게 되는 데, 황동의 경우 그 강도가 약해, 압착력에 의해 파손될 수 있어, 가해지는 압력을 각 부분에 일정하게 해주도록 하여 그 강도를 보상할 수 있도록 있도록 하는 것이다.This is because the wire connection terminal 30 of the power plug generally uses brass in consideration of production cost compared to conductivity. In the case of brass, the strength thereof is weak and can be damaged by the compressive force. To make sure that the strength is compensated.
이와 같은 본 발명 실시예의 작업공정을 살펴보면 다음과 같다.Looking at the working process of the embodiment of the present invention as follows.
먼저, 전선(20)의 피복을 벗긴후, 도 2에서와 같은 1차 케이스(40) 조립체에 외부로 나타난 전선결합부(31)에 형성된 도선삽입공(31a)에 도선(21)을 끼워 삽입시킨다.First, after the coating of the wire 20 is removed, the wire 21 is inserted into the wire insertion hole 31a formed in the wire coupling portion 31 which appears to the outside of the primary case 40 assembly as shown in FIG. 2. Let's do it.
도선(21)이 삽입된 상태에서 전선결합부(31)의 외부면에 별도의 가압장치를 이용하여 압착시킨다.In the state in which the wire 21 is inserted is pressed using an additional pressing device on the outer surface of the wire coupling portion 31.
상기와 같이 전선결합부(31)의 외부면을 압착시켜면, 전선결합부(31)가 눌려지면서, 도선삽입공(31a)내에 도선(21)을 전선결합부(31)의 내부면에 접속된 상태로 고정시킨다.When the outer surface of the wire coupling portion 31 is crimped as described above, the wire coupling portion 31 is pressed, and the conductive wire 21 is connected to the inner surface of the wire coupling portion 31 in the wire insertion hole 31a. In the closed state.
이후, 도 4에서와 같이, 2차 케이스(50)를 1차 케이스(40)에 끼워 고정시켜 작업을 완료한다.Thereafter, as shown in FIG. 4, the secondary case 50 is fitted into the primary case 40 to fix the work.
이상에서 설명한 바와 같이, 본 발명은 도선을 전선접속단자내에 삽입시키고, 그 외부에서 압착시켜, 압착력에 의해 도선이 전선접속단자내에 접속 고정되도록 하는 것으로, 간단하게 전선을 접속 고정시킬 수 있다.As described above, in the present invention, the wire is inserted into the wire connection terminal and crimped from the outside thereof so that the wire can be connected and fixed in the wire connection terminal by the crimping force.
