Description

Safety wire connector {Safety wire connector}

The present invention relates to a safety wire connector that can be safely used to overcome the shortcomings of the existing plug-in connector used for the connection of cords, cables, wire harnesses, and other wires.

1 shows an example of a known conventional wire connector. It is a general electric wire connector in which the plug 11 and the receptacle 13 are attached to the ends of both electric wires, respectively. Conductive terminals or pins 15 are mounted in the housings of the plugs 11 and the receptacles 13, respectively, and are inserted into and electrically connected to each other.

However, since the plug-in connector of Fig. 1 is not easy to be disconnected once it is connected, it is inadequate in a place to be detached frequently.

In addition, it is unsuitable for use as a preferable use in that both wires are removed in case of emergency. For example, when both wires are pulled together and the tension is applied, the connector must be detached or a safety accident is concerned so as not to damage the wires. For example, if you are wearing headphones or earphones and you are listening to music, there is a risk that the headphone or earphone string may be caught around your neck while you are sleeping. In addition, there is a problem that the jack-plug coupling portion is damaged, such as when the sound device is spaced farther than the earphone string length while the plug is inserted.

The present invention has been made to overcome the problems of the conventional insert-type wire connector as described above, by making it possible to connect the wire connector in a contact manner using a magnet to make it easy to attach and detach. There is a need for a wire connector that can be easily attached and detached from the risk of a safety accident.

Accordingly, an object of the present invention is to provide a safety wire connector that is provided with permanent magnets on both sides of the connector and reduces contact resistance between the contact pin and the terminal and is easily connected, unlike the conventional insert connector.

1 is an example of a conventional wire connector.

Overview of the devise

The present invention has a basic concept of configuring a wire connector in a contact type, unlike a conventional insert connector. In other words, when the permanent magnets are provided on both sides of the connector for connecting the two wires and the two connectors are close to each other, the two connectors are coupled by the magnetic force of the permanent magnet.

Thus, when manufacturing a contactor by a contact type, the following are considered.

First, when the contact type design as in the present invention compared to the conventional forced insertion formula there is a fear that the contact resistance between the terminals to be connected, the structural problem should be solved.

Second, in the case of connecting a plurality of wires, the insertion direction of the existing plug and the receptacle is determined by the shape of the housing, and according to the present invention, even if the user contacts the connector without any effort, the individual wires are easily connected independently. Should have a structure that can be.

Preferred embodiments that solve these problems will be described in detail with reference to the drawings.

Example 1

Figure 2a shows a longitudinal sectional view of a preferred embodiment of a safety connector using a magnet according to the present invention.

The first housing 100 and the second housing 200 are interconnected to connect two wires. The first housing 100 and the second housing 200 are processed in an empty form so that an electric wire can enter the inside of the first housing 100 and the second housing 200.

In the portions where the first housing 100 and the second housing 200 are in contact with each other, a concave recess 102 and a convex protrusion 202 are formed, respectively. These recesses and protrusions are coupled to each other when the first housing 100 and the second housing 200 are in contact so that both housings are connected correctly.

Permanent magnets 104 and 204 are installed in each housing in contact with the recess 102 and the protrusion 202. Where both are permanent magnets, they must be of different polarities. Otherwise repulsive forces act on each other.

However, according to the basic idea of the present invention, only one of them may be a permanent magnet and the other one may be a magnetic material such as iron or nickel. However, in the present embodiment, it was assumed that both are permanent magnets in order to strengthen the contact force of both housings. As a result, a large contact force can be obtained even with a relatively small permanent magnet.

A plurality of contact pins 106 are embedded around the recess 102 of the first housing 100, and a plurality of terminals 206 are embedded around the protrusion 202 of the second housing 200. 2A, it can be seen that the contact pin 106 is embedded to slightly protrude from the end surface of the first housing 100. The terminal 206 is also embedded to enter in at the end face of the second housing 200. To this end, the end surface of the second housing 200 is slightly recessed inward.

2B is a detailed view of the contact pin 106 embedded in the first housing 100. It can be seen that the movable pin 110 is inserted into the pin cylinder 108 and is always receiving a force pushed outward by the elastic force by the spring 112. Therefore, in order to push the movable pin 110 from the right side to the left side of Figure 2b it must be given a constant force by the elastic force of the spring (112). That is, once the movable pin 110 has entered, there is always a force pushing outward (from the left to the right in FIG. 2B). The contact pin of FIG. 2B is a so-called "pogo pin" widely used in semiconductor test jigs and the like.

As a result, the contact pin 106 may firmly contact the terminal 206 when the first housing 100 and the second housing 200 are in contact with each other. 2C shows a state in which both housings are in contact with each other. The indentation and the protrusion are firmly coupled by two permanent magnets, and the contact pin is firmly in contact with the terminal by the spring inside.

Example 2

2A and 2C have been described with a minimum of two contact pins and a terminal, but a plurality of contact pins / terminals are often required for practical application. It is obvious that such a structure also does not have a balance with the structure of the above-described embodiment. However, when a plurality of contact pins and terminals are to be interconnected as described above, only the types in which the contact pins and the terminals coincide with each other should be in contact with each other, so that the first housing 100 and the second housing 200 contact only in one direction. You need to do it.

To this end, various methods can be adopted.

As shown in FIG. 3A, the recess 102 of the first housing 100 is provided with a protruding key 114 formed by protruding a portion of the circumference of the recess 102 toward the center portion of the first housing 100. The protruding portion 202 is formed with a key groove 214 in which a circumferential portion of the protruding portion is recessed toward the center. Therefore, the first housing 100 and the second housing 200 are coupled only when the direction and angle of the protruding keys and the key grooves match.

In addition, the key pin 114 ′ is formed at an arbitrary position shifted from the center position in the recess 102, and the key pin hole 214 ′ is formed therein at an arbitrary position shifted from the center position of the protrusion 202. Indicates. Here, the first housing 100 and the second housing 200 are coupled only when the key pin 114 'and the key pin hole 214' are aligned.

The above case is possible when the first housing 100 and the second housing 200 are in contact with each other in a direction and an angle. Therefore, there is a disadvantage in that it takes a relatively long time to contact. To overcome this, a housing may be formed as shown in FIG. 3B. In this case, even when the first housing 100 and the second housing 200 are contacted at any position, each of them may be slightly moved by itself to be coupled at the correct position. As shown in FIG. 3B, the shape of the recess 102 and the protrusion 202 of the second housing 200 are machined into a claw shape of the engagement clutch, which is a known mechanical element. Similarly to the operation of the engagement clutch, even if the first housing 100 and the second housing 200 are roughly approached, they are coupled to each other by finding the exact position by the claw.

Although the embodiment of the safety connector using a magnet according to the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment and should not be interpreted. The technical scope of the present invention should be determined by reasonable interpretation of the matters described in the utility model registration claims.

According to the present invention, since the wire connector can be configured as a contact structure by the magnetic force of the permanent magnet, it is more easily detachable than the existing plug connector and can be detached with a small force. It is effective to protect the user or the device body. The safety wire connector according to the present invention can be effectively applied to a portable cassette or a CD player, an MP3 player, a mobile phone, an acoustic vibrator or a hands-free device installed in a vehicle.
