Description

단자위치보증부재{TERMINAL POSITION ASSURANCE}Terminal position guarantee member {TERMINAL POSITION ASSURANCE}

본 발명은 단자를 수용하며, 단자의 위치를 고정하는 랜스를 포함하는 방수 커넥터에 사용되는 단자위치보증부재(terminal position assurance)에 관한 것이다.The present invention relates to a terminal position assurance member for use in a waterproof connector that contains a terminal and includes a lance for fixing the position of the terminal.

전기 커넥터는 일반적으로 커넥터와 커넥터, 또는 커넥터와 접속 가능한 접속장치들을 결합시켜 통전가능하게 하는 장치를 말한다. 이러한 커넥터는 내부에 단자를 수용할 수 있는 공간을 갖추고 있으며, 나아가 다수개의 단자들을 한개의 커넥터에 수용하기도 한다.An electrical connector generally refers to a connector and a connector, or a device that connects and connects a connector to a connector to enable energization. Such a connector has a space for accommodating terminals therein, and also accommodates a plurality of terminals in one connector.

이러한 커넥터는 전기적인 접속을 하기 위한 것이기 때문에 다른 접속장치와의 확실한 전기적, 기계적 결합을 필수적인 사항으로 한다. 따라서, 이러한 확실한 결합을 보증하기 위해서 여러가지 수단이 사용된다.Since these connectors are intended for electrical connections, certain electrical and mechanical couplings with other connectors are essential. Thus, various means are used to ensure this secure coupling.

TPA(terminal position assurance)는 단자가 커넥터에 수용되어 확실하게 커넥터와 결합되었는지를 검증하고 보증하기 위한 장치로 사용되며, 통상적으로 커넥터의 전면에서 삽입되어 단자가 커넥터에 삽입되면 단자를 고정하는 랜스와 접촉가 능하게 하여, 단자가 제자리에 결합되지 않으면 랜스가 TPA와 접촉되도록 하여 더 이상 TPA가 삽입되지 못하게 하여 단자의 결합불량을 판단할 수 있도록 한다.Terminal position assurance (TPA) is used as a device for verifying and assuring that a terminal is received in the connector and securely mated with the connector.TPA is usually inserted from the front of the connector to secure the terminal when the terminal is inserted into the connector. If the terminals are not in place, the lance will come into contact with the TPA so that no further TPA can be inserted, so that the terminal can be decoupled.

커넥터의 경우 누전이나 접속불량을 방지하기 위해 방수를 하게 된다. 그에 따라 방수씰(seal)을 장착하게 된다. 방수씰을 사용하고 TPA를 사용하는 경우, 우선적으로 결합공간에 방수씰을 넣은 후 TPA를 그 위에 장착하게 된다.The connector is waterproof to prevent short circuits or poor connection. As a result, a waterproof seal is mounted. In the case of using a waterproof seal and using a TPA, the TPA is first mounted on the waterproof seal in the bonding space.

하지만 이러한 경우 TPA는 쉽게 제거가 가능하지만 방수씰은 좁은 공간에 들어가서 잘 나오지 않게 된다. 또한 장착할 때에도 좁은 공간에 방수씰을 밀어 넣어야 하는 불편함이 있었다.However, in this case, the TPA can be easily removed, but the waterproof seal enters a narrow space and does not come out well. In addition, there was an inconvenience to push the waterproof seal in a narrow space when mounting.

따라서 본 발명은 상기와 같은 불편함을 해결하기 위한 것으로 커넥터에 방수씰과 TPA의 장탈착이 용이한 단자위치보증부재를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a terminal position assurance member that is easy to remove the waterproof seal and TPA in the connector to solve the inconvenience as described above.

본 발명은 상기와 같은 과제를 해결하기 위하여 다음과 같은 구성을 가진다.The present invention has the following configuration to solve the above problems.
