Description

Socket terminal {SOCKET TERMINAL}

The present invention relates to a socket terminal, and more particularly to a socket terminal inserted into a socket for electrically connecting different devices.

The socket is an inlet for supplying electricity to a fluorescent lamp, a light bulb and the like and a mechanism for supporting them.

The socket is provided with a socket terminal into which an electric wire is inserted to supply electricity to the lamp. The socket terminal must have an electric wire for supplying power to the clamped lamp terminal. Thus, the socket terminal is provided with a structure that prevents the wire from being pulled out in an undesired situation.

1 shows a perspective view of a conventional socket terminal.

According to these figures, a substantially plate-shaped body 1 is provided. The body 1 has a shape that can be inserted into the socket housing (not shown). A first vertical portion 2 and a second vertical portion 3 extending side by side in the longitudinal direction of the body 1 and positioned substantially perpendicular to both ends of the body 1 are provided.

Only part of the first and second vertical portions 2, 3 are connected to the body 1, and the length thereof is different. That is, it can be seen that the length of the first vertical portion 2 located in the upper direction is longer than that of the second vertical portion 3 located in the lower direction.

The contact pressing portion 4 is further extended to the first vertical portion 2 and the contact pressing portion 4 extended to be positioned on the upper surface of the body 1 is bent. In the second vertical portion 3, the insertion hole forming portion 6 in which the insertion hole 5 is formed is further extended and bent. Since the contact pressing portion 4 is longer than the insertion hole forming portion 6, the contact pressing portion 4 is further inwardly positioned.

In this case, the contact pressing portion 4 may be extended to the second vertical portion 3 and the insertion hole forming portion 6 may be formed on the first vertical portion 2. However, the insertion hole forming portion 6 is formed to be substantially vertical and the contact pressure portion 4 should be formed to be bent inward more than the insertion hole forming portion (6).

On the other hand, a part of the other end of the first, second vertical portion (2) (3) is bent in the inclined direction facing each other in a state cut off from the body (1) while the lamp connection portion 7 is formed so that the end is opened again do. The lamp terminal is fitted to the lamp connecting portion 7.

When the electric wire is fastened by the socket terminal of such a structure, an electric wire passes through the insertion hole 5 by an external force, and the front end of the electric wire is pushed against the contact press part 4, and the contact press part 4 It is further bent in the direction bent by external force, providing space for the wire to pass through.

It is preferable to insert the electric wires until they come into contact with the lamp terminals fixed to the lamp connecting portion 7. This completely secures the wires. In this state, the wire is not easily pulled out because the contact is in contact with the pressure portion (4).

On the other hand, in the case of disconnecting the electric wire, an external force is applied directly to the contact pressing part 4 so that the contact pressing part 4 is bent inward from the current position. Then, the end of the contact pressing portion 4 is spaced apart from the wire, so that the wire can be pulled out of the socket terminal by pulling the wire.

However, the socket terminal as described above has the following problems.

End of the contact pressing portion 4 may be in close contact with the inner surface of the second vertical portion (3) facing. Then, if the adhesion force is greater than the force when inserting the wire, it is difficult to insert the wire because there is no space for the wire to be inserted. That is, the contact pressing portion 4 may not be elastically deformed.

In addition, although the insertion hole 5 is formed, there is a limit on the thickness of the wire that can be inserted into the socket terminal. However, when the wire is forcibly inserted or when the external force is directly applied to the contact pressure part 4 when the wire is separated, the contact pressure part ( 4) can be severely bent in the bent direction there is a problem that can not be restored to its original position despite the elastic restoring force. In this case, there is a problem that the wire can be easily pulled out because the wire is not in close contact with the contact pressurizing unit 4.

Moreover, no protruding structure is provided on the back of the socket terminal. Therefore, when the electric wire is pulled out while the socket terminal is mounted on the socket housing, a problem arises in that even the socket terminal is accidentally detached from the socket housing.

Therefore, an object of the present invention is to solve the problems as described above, and to prevent the contact pressing portion from the socket terminal to be in close contact with the inner surface of the vertical portion.

Another object of the present invention is to limit the bending angle in which the contact pressing portion can be elastically deformed.

Another object of the present invention is to prevent the socket terminal from being pulled out of the socket housing when the electric wire is disconnected while the socket terminal is mounted on the socket housing.

According to a feature of the present invention for achieving the above object, the body consisting of a plate; First and second vertical portions provided on both sides of the body; It comprises a contact pressing portion and the insertion hole forming portion extending in the length direction of the body different from each other from the first and second vertical portion, the contact pressing portion is bent while being further bent into the insertion hole forming portion, The locking projection is formed on the second vertical portion inner surface so that the end of the contact pressing portion does not come into close contact with the inner surface of the second vertical portion, and is bent to limit the bending angle of the contact pressing portion when the electric wire is fitted through the insertion hole forming portion. A stopper is formed on the upper surface of the body in the direction.

It is formed on the front end of the socket terminal is further formed with a locking step that is hooked to the hook projection of the counterpart.

According to the socket terminal of the present invention having such a configuration, there is an advantage in that the wire insertion is easy, the wire is easily prevented from being pulled out, and the socket terminal is prevented from being detached from the socket housing when the wire is pulled out.

In the socket terminal structure of the present invention having the above configuration, the following effects can be expected.

First, the contact pressing portion is prevented from coming into close contact with the inner surface of the vertical portion, so that the electric wire can be easily fastened to the socket terminal.

In addition, since the bending angle of the contact pressing portion is limited, as a result, there is less force to provide the force beyond the elastic limit, so that the restoring force to the original position is large, and thus the close contact force with the wire is maximized, so that the wire can be minimized in an undesired situation. have.

In addition, since the socket terminal is caught by the socket housing, it is possible to prevent the socket terminal from being separated from the socket housing together with the wire when the electric wire is pulled out.

Hereinafter, a socket terminal structure according to the present invention will be described in detail with reference to a preferred embodiment shown in the accompanying drawings.

2 is a perspective view showing a preferred embodiment of the socket terminal according to the present invention, Figure 3a is a plan view, Figure 3b is a rear view.

Referring to these figures, a substantially plate-shaped body 10 is provided. The first and second vertical portions 20 and 30 extend side by side in the longitudinal direction of the body 10 and are orthogonal to both ends of the body 10.

Only a part of the first and second vertical portions 20 and 30 is integrally connected to the body 10, and the lengths of the first and second vertical portions 20 and 30 are different from each other. That is, in the drawing, it can be seen that the first vertical portion 20 positioned at the upper side extends longer than the second vertical portion 30 positioned at the lower side.

The contact pressing portion 22 is formed at an extended portion of the first vertical portion 20 and the contact pressing portion 22 is bent in the direction of the body so as to be positioned on the upper surface of the body 10. An insertion hole forming part 32 having an insertion hole 34 is formed at an extended portion of the second vertical portion 30. Since the contact pressing portion 22 is longer than the insertion hole forming portion 32, the contact pressing portion 22 is further bent in the body direction.

In this case, the contact pressing portion 22 may be formed to extend in the second vertical portion 30 and the insertion hole forming portion 34 may be formed in the first vertical portion 20.

The stopper 40 is formed in the body 10. The stopper 40 is a part of the body 10 is cut and bent, serves to limit the movement range of the contact pressing portion 22.

A locking projection 36 is formed on the inner surface of the second vertical portion 30 corresponding to the end of the contact pressing portion 22. The locking protrusion 36 also cuts and protrudes a part of the second vertical portion 30. The locking projection 30 prevents the end surface of the contact pressing portion 22 from coming into close contact with the inner surface of the second vertical portion 30. The contact pressing part 22 may be easily operated when the electric wire is inserted by having a slight distance from the second vertical part 30.

Here, the locking projection 36 and the stopper 40 may be formed by using a separate member in the above-described forming portion.

A locking jaw 50 is formed at the front end of the socket terminal. The locking jaw 50 is hooked to the hook protrusion 72 (see FIG. 5) formed in the socket housing 70 (see FIG. 5). Thus, with the socket terminal mounted on the socket housing, the wires do not fall out when only the wires are pulled out but instead prevent the socket terminals from falling out of the socket housing.

On the other hand, a part of the other end of the first and second vertical portion 20, 30 is bent inclined inwardly in a state in which it is cut in the body 10 while the end portion is open to the lamp connecting portion provided with a slight gap 60 is formed. The lamp terminal is fitted and fixed to the lamp connecting portion 60.

Hereinafter, the operation of the socket terminal according to the present invention having the configuration as described above in detail.

The present invention will be described with reference to Figures 4a to 4c as the wire is inserted into the socket terminal is coupled, the wire is separated from the socket terminal by a predetermined external force is applied in the coupled state.

First, the wire is inserted into the socket terminal.

As shown in FIG. 4A, when the wire W is moved in the direction of the arrow through the insertion hole 34, the tip of the wire W comes into contact with one surface of the contact pressing part 22, and if the external force is continuously applied, 22 is bent in the direction of the stopper 40 by the external force. At this time, the contact pressing portion 22 is not closely contacted with the second vertical portion 30 by the engaging projection 36 formed on the inner surface of the second vertical portion 30 so that the wire W is easily inserted. .

And if the wire (W) continues to be inserted, the wire (W) pushes up the contact pressing portion 22 and eventually the bottom surface of the contact pressing portion 22 is in close contact with the outer peripheral surface of the wire (W). This state is the state of FIG. 4B. That is, it can be seen that the contact pressing portion 22 is deformed from the initial dotted line position to the solid line position.

At this time, even if the front end of the wire (W) is in contact with the contact pressing portion 22 when the electric wire (W) is inserted, the force is continuously applied, the contact pressing portion 22 is stopped by the stopper 40. . In other words, the contact pressing part 22 is prevented from being severely elastically deformed.

As shown in FIG. 4B, when the wire W is fastened to the socket terminal and electrically connected to the socket housing, the lamp coupled to the socket housing is driven.

On the other hand, when the external force is applied to the contact pressing portion 22 of the socket terminal in the state in which the wire (W) is fastened to the socket terminal will be described to separate the wire from the socket terminal.

In the state as shown in FIG. 4B, the force is applied to the contact pressurizing unit 22 using the constant tool P as shown in FIG. 4C. Then, as illustrated in FIG. 4C, the contact pressing part 22 is raised from the dotted line to the dashed-dotted position, and thus is spaced apart from the wire W. FIG.

In this state, when the wire W is pulled in the direction of the arrow, the wire is easily pulled out without any interference.

When the wire W is completely removed from the socket terminal, and the force applied to the contact pressing portion 22 is removed, the contact pressing portion 22 is restored to the original position indicated by the solid line.

5 is a cross-sectional view of the socket terminal of the present invention coupled to the socket housing.

Referring to FIG. 5, when the socket terminal is mounted in the socket housing 70, the locking projection 50 of the socket terminal may be caught by the hook protrusion 72 of the socket housing 70. Therefore, when the wire W is to be removed from the socket terminal, the socket terminal is prevented from being pulled out of the socket housing even when the wire W is not pulled out.

If the socket terminal is to be pulled out, if the socket terminal is pushed slightly to the left in the drawing and then lifted, the locking jaw 50 is separated from the hooking part 72, and thus the socket terminal can be removed.

Although described with reference to the illustrated embodiment of the present invention as described above, this is merely exemplary, those of ordinary skill in the art belonging to the present invention without departing from the spirit and scope of the present invention various modifications It will be apparent that other embodiments may be modified and equivalent.
