Description

[Detailed description of the invention] "Industrial application field" This invention is based on a cord that connects a magnetic recorder attached to a motorcycle and a headphone, which is held in a helmet and comes off when the motorcycle falls over. It relates to a safety connector that prevents it from getting wrapped around the neck and creating a dangerous situation.

``Prior Art'' In a conventional safety connector of this type, one end of a fixed part 11 is attached to a helmet 12, as shown in FIG.
3 is inserted and held, and by connecting the mating connector 14 to the connector body 13, the headphone connected to the connector body 13 and the tape recorder connected to the connector 14 are electrically connected to each other. are doing. When the motorcycle falls, the connector body 13 and the mating connector 14 are disconnected, so there is no risk that the cord 10 between the connector 14 and the tape recorder will wrap around the neck.

Conventionally, as shown in FIG. 7, one end of the connector main body 13 is inserted into the fixing part 11 and fixed thereto, and the fixing part 1 is connected to the fixing part 1 through the inserted part.
A lead wire 15 was led out from the inside of the housing. The lead wire 15 is connected to a contact held within the connector body 13.

In this way, conventionally, the lead wire 15 is inserted into the fixing part 11, so the connector body 1
If the lead wire 15 is repeatedly bent at the connecting portion 18 between the connector body 13 and the fixing portion 11, or if a strong tensile force is applied to the connector body 13, there is a risk that the lead wire 15 will break.

The purpose of this invention is to provide a safety connector that is free from the risk of disconnection even if a strong force is applied to the connector body or the connection portion with the fixed portion is repeatedly bent.

``Means for solving the problem'' According to this invention, the connector body is held in the fixed part, but the lead wires connected to the contacts of the connector body are led out from the connector body part, and the leads are held in the fixed part. Do not pass the line.

``Example'' For example, in FIG. 1, parts corresponding to those in FIG. The lead wire 15 is led out directly from the connector body 13 and is held without passing through the fixing part 11. Therefore, even if the connecting part 13a between the connector main body 13 and the fixed part 11 is repeatedly bent, the lead wire 15 itself will not be bent so much because the lead wire 15 is not passed through it. Even when bent, the bending angle is relatively large and there is no risk of wire breakage. Furthermore, even if the connector main body 13 receives a strong tensile force, only the connecting portion 13a is pulled against the fixed portion 11, and the lead wire 15 is separated from the fixed portion, so there is no risk of receiving a strong tensile force. do not have.

2 to 5 show other examples of the safety connector of this invention. One end of the fixed part 11 is the mounting part 11
A, a hole 19 is formed in the attachment portion 11a, and the fixing portion 11 is attached to a helmet using this hole. A connector body 13 is integrally formed at the other end of the fixing part 11, and the front surface of the connector body 13 has a ring-shaped recess into which the cylindrical part of the mating connector is inserted, as shown in FIGS. 4 and 5. 21 is formed. Inside the ring-shaped recess 21, a further recess 2 is provided.
2 is formed, and a contact 24 is formed in the recess 22.
is held in the connector body 13. Fixed part 1
Reference numeral 1 is a plate-shaped piece, which is integrally extended in the front-rear direction of the connector body 13 at one edge of the back surface of the connector body 13, and faces the fixed part 11 on the back surface of the connector body 13, and A lead wire lead-out portion 24 is integrally formed so as to extend obliquely, and the lead wire 1 is connected from the lead wire lead-out portion 24.
5 is led out. Lead wire 15 is connected to contact 23 as shown in FIG.

"Effect of the invention" As described above, according to the safety connector of this invention, the lead wire 15 connected to the contact of the connector body
is led out from the connector body 13 and not from the fixed part 11, so
Even if the connection part between the fixing part 11 and the connector body is repeatedly bent, the lead wire 15 is hardly affected, that is, the bending has a small radius of curvature, and there is no risk of the lead wire 15 being broken. Furthermore, even if the connector main body 13 receives a strong tensile force, the lead wire 15 is not fixed to the fixed part 11 due to the strong tensile force being applied between the fixed part 11 and the connector main body 13. There is no risk of receiving strong force from 15. Therefore, it is difficult to break the wire.
