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.

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.

Terminal position assurance (TPA) is used as a device to verify and assure that the terminal has been received in the connector and is securely coupled to the connector.The holder keeps the terminal securely coupled to the connector. Used as a device to guarantee position.

The TPA is typically inserted from the front of the connector to enable contact with the lance that holds the terminal when the terminal is inserted into the connector, so that the lance contacts the TPA if the terminal is not in place, so that no further TPA can be inserted. Check the coupling failure of the terminal.

The holder is inserted at the side or top of the connector so that it overlaps with a portion of the terminal, preventing movement of the terminal in the connector and preventing it from being pulled out. In particular, the insert from the side of the connector is called a side holder (side holder).

However, such a connector generally has a separate part of the TPA and the side holder, so that they are manufactured and coupled to the connector. In this case, there is a problem that an increase in the number of parts increases the assembly time, a work defect caused by the increase in the number of parts.

The housing 10 has a plurality of accommodation spaces for accommodating the terminals, and the accommodation spaces are open to both sides so that the terminals can be accommodated and can be connected to other terminals. The housing not only provides a coupling space for the terminals, but also serves to prevent terminal damage or safety accidents.

The housing is intended to include a lance 11 into which the terminals can be coupled in a space for accommodating the terminals, and a first through hole 12 and a second through hole 13 penetrating from the side of the housing. It is composed. In addition, the housing may further include a connector position assurance (CPA) 30.

As can be seen in Figure 4, the lance 11 is elastic and has a structure that can be fixed to the terminal when the terminal is accommodated, the lance is a known technique as a structure used for a general connector.

In FIG. 1, the first through hole and the second through hole are configured to allow the terminal position side holder to penetrate and engage with the housing.

The connector position assurance (CPA), as shown in Fig. 1, ensures that the lever 14 does not operate arbitrarily at the time of engagement between the connectors with the connector position assurance means.

As can be seen in Figure 3, the terminal position guarantee side holder 20 has a long extended holder portion for fixing the position of the terminals in the housing, a position guarantee portion to ensure the coupling position of the terminals, and the position with the holder portion It comprises a connecting portion for connecting the guarantee.

The holder portion 21 has a rod-shaped configuration extending in length and penetrates through the first through hole of the housing to fix the terminals in the housing. Common terminals have a configuration such as a locking groove on one side of the terminal, so that when the terminals are arranged in a line, the rod-shaped holder part passes through the housing and is caught by the locking groove. Accordingly, as shown in FIG. 4, the terminals are fixed in the housing by the holder so that the position thereof does not change.

The position assurance unit 22 is configured to ensure that the terminals accommodated in the housing are properly coupled with the lance, and has a function of ensuring the position of the terminals in the housing.

The position assurance part 22 may include a coupling passage part 24 having a through path in which the terminals are coupled to terminals of another connector, and formed in accordance with the arrangement of the terminals, and at least one side facing the lance of the coupling passage part. It includes a lance contact portion 25 is formed so as to protrude to the terminal side but has an inclination to reach the end portion is reduced in cross section.

As shown in FIG. 3, the coupling passage portion 24 has a plurality of through passages arranged on the front of the position assurance portion, and allows the terminal to be connected therethrough.

The lance contact portion 25 is formed to protrude toward the terminal side from at least one side facing the lance and has an inclination toward the end portion and is reduced in cross section. When the terminal is not coupled to the lance, the lance is elastically deformed and protrudes, so that the lance contact part inevitably comes into contact with the lance when the position assurance part enters through the second through hole.
