Abstract

The present invention relates to a connector. In the connector 10 of the present invention, the coupling of the plurality of terminals 30 with the corresponding mating terminals 40 of the mating connector 30 occurs at a time difference in engagement with the mating connector 30. Therefore, when the connector 10 is coupled with the mating connector 30, there is an effect that the required coupling force is relatively reduced.

Description

Connector {Connector}

The present invention relates to a connector, and more particularly, to a connector in which the mating with the mating terminal does not occur simultaneously with the mating connector.

The connector is made of an insulating material and the terminal is made of a conductive material is installed in the housing to form the appearance and the skeleton, it is coupled with the mating connector to perform an electrical connection.

The connector may be provided with a plurality of terminals. When the number of terminals increases, the coupling force increases in proportion to the number of terminals when engaging with the mating terminal of the mating connector. Therefore, when the number of terminals increases, the coupling force for the coupling between the connector and the mating connector is increased so that it is difficult for a worker to join the mating connector and the mating connector.

In order to solve this problem, a lever-type connector has been developed that amplifies the force provided by an operator using a lever that acts as a lever so that the connector and the mating connector are coupled with a relatively small force.

However, in the lever type connector, a lever is installed in one of the connectors coupled to each other, and the lever needs to be rotated with a predetermined trajectory, so that a space for operating the lever is large, such as a space for operating the lever. There is a problem. In particular, in the case of a connector installed in a narrow space, there is a problem that it is impossible to operate the lever.

As shown in FIG.

The stepped portion 16 'is formed between a row formed at an upper side and a row formed at a lower side among the rows of the terminal installation space 16 in the present embodiment. This is because the terminal mounting space 16 is made of two rows of upper and lower in this embodiment, and the stepped portion 16 'is made in this way because the positions of the terminal mounting spaces 16 in these upper and lower rows are different from each other. However, the stepped portion 16 'may be formed between the adjacent terminal installation spaces 16, for example, rather than between the upper and lower rows.

In the present embodiment, a plurality of terminal seating spaces 116 are formed in two rows up and down. The front surface of the housing 112 has a step 116 ′ caused by the formation position of the terminal seating space 116 is different.

The spring 123 is in close contact with the coupling portion 142 of the mating terminal 140 to be described below to maintain the coupling state with the coupling portion 142.

The terminal 120 is installed at different positions in the housing 112 because the terminal seating space 116 is located at different positions in the longitudinal direction of the connector 110. For example, in this embodiment, the terminals 120 in the upper row are in a retracted position, and the terminals 120 in the lower row are in a relatively advanced position. In the present invention, the positions of the terminals 120 do not necessarily vary depending on the heat.

Next, a configuration of the mating connector 130 coupled with the connector 110 will be described with reference to FIG. 6. The mating housing 132 forms the appearance and skeleton of the mating connector 130. A coupling space 134 is formed inside the mating housing 132 so as to open at the tip. The front end of the connector 110 is inserted into the coupling space 134, and the terminal 120 and the mating terminal 140 to be described below are coupled to each other.

A terminal seating space 136 is formed through the mating housing 132 to connect the outside of the coupling space 134 and the mating housing 132. The terminal seating space 136 is inserted into the mating terminal 140 to be described below is installed. A lance 138 is formed in the terminal seating space 136.

Hereinafter, the use of the connector according to the present invention having the above-described configuration will be described in detail.

First, the connector 10 of the embodiment shown in FIG. 1 will be described with reference to FIG. 3.

As can be seen in Figure 3 (a) in the connector 10, the terminal seating space 16 is formed at different positions in the longitudinal direction of the connector (10). In particular, in this embodiment, the terminal seating space 16 in the upper row is in a relatively advanced position, and in the lower row is in a relatively retracted position. Thus, when using the same terminal 20, the terminal 20 in the terminal seating space 16 in a relatively advanced position is relatively more protruding.

Thus, as shown in (b) of FIG. 3, the first coupling with the coupling part 42 in the mating terminal 40 of the mating connector 30 is the terminal of the terminal seating space 16 in the advanced position. (20).

Next, when the connector 10 and the mating connector 30 continue to be mated, as shown in (c) of FIG. Begins to couple with terminals 40.

As such, when the terminal 20 and the counter terminal 40 are coupled with a time difference, the coupling force is distributed and necessary. Therefore, the magnitude of the maximum coupling force required at the time of coupling between the connectors 10 and 30 is reduced by half in this embodiment.

3 (d) shows a state in which the connector 10 and the mating connector 30 are completely coupled. As can be seen here, in the coupling between the terminal 20 and the mating terminal 40, the position where the engaging portion 22 of the terminal 20 and the spring 43 of the mating terminal 40 is in contact Is set.

Next, the connector 110 of the embodiment shown in FIG. 4 will be described with reference to FIG. 6.

As shown in FIG. 6A, the positions of the terminals 120 of the connector 110 are different from each other. That is, those installed in the terminal seating space 16 in the upper row of the terminal 120 is in a relatively retracted position in the longitudinal direction of the connector 110, the remaining terminals 120 are in a relatively advanced position.

Accordingly, when the coupling between the two connectors 110 and 130 proceeds, first, the terminal 120 in the lower row of the connector 110 starts to engage with the mating terminal 140 of the corresponding mating connector 130 first. This can be seen in Figure 6 (b).

Next, in FIG. 6C, the terminal 120 and the relative terminal 140 in a relatively retracted position are coupled. The state in which the mating between the mating connector 130 and the connector 110 is completed is shown in FIG.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.

For example, in the illustrated embodiments, the terminals 20, 40, 120, 140 were identical in shape and dimensions to those used in the respective connectors 10, 30 (110, 130). The purpose of the present invention can be achieved by varying the length of the coupling part 22 or the coupling part 142 of the terminal 140. That is, the lengths of the coupling parts 22 and 142 of the tab terminals 20 and 140 are different. If it is possible to be sequentially coupled with the corresponding terminals (40,120) it is possible to lower the coupling force.

In the illustrated embodiment, only the steps 16 'and 116' are extended to the left and right, but the terminal seating space may be formed so that the steps extend upward and downward.
