It consists of a contact portion 65 in electrical contact with the second terminal 80 of the two connector (70).

In this embodiment, the contact portion 65 extends straight in one direction without being bent to be in close contact with the outer surface of the partition wall 54. That is, the entirety of the contact portion 65 is completely fixed to the terminal seating groove 55 '. This is to increase the coupling area between the first terminal 60 and the inner housing 51 so that the first terminal 60 is more firmly fixed to the inner housing 51.

On the other hand, the connector housing 71 forms the appearance and skeleton of the second connector 70. The connector housing 71 is also formed of a synthetic resin material, and is formed in a substantially rectangular parallelepiped shape. The terminal hole 73 is formed in the connector housing 71. The terminal hole 73 is opened to the front end of the connector housing 71 so that the partition wall 54 can be inserted. A mounting end 74 protruding into the terminal hole 73 is formed at the front end of the connector housing 71. The outer surface of the seating end 74 is a part seated on the bottom surface of the coupling space 52 of the inner housing 51 when the second connector 70 and the first connector 30 are coupled. In addition, the inner surface of the seating end 74 supports the tip of the second terminal 80 to prevent the second terminal 80 from being detached from the terminal hole 73.

A chamfer 74 'having an inclination corresponding to the insertion guide surface 59 is formed on the outer surface of the front end of the connector housing 71. The chamfer 74 ′ guides the front end of the connector housing 71 to be easily inserted into the coupling space 52.

The terminal hole 73 is provided with a dividing wall 75 for partitioning the terminal hole 73. The second terminals 80, which are seated to face each other in the terminal hole 73, do not contact each other by the separation wall 75.

The terminal hole 73 is provided such that the second terminal 80 faces each other around the separation wall 75. The second terminal 80 may include a lead portion 81 mounted on a second substrate, a fixing portion 82 fixed to the inner surface of the terminal hole 73, and a tip of the fixing portion 82. Spring portion 83 is bent in the elastically deformed direction in the direction in close contact with the inner surface of the terminal hole 73, and formed on the front end of the spring portion 83 is supported on the inner surface of the terminal hole 73 The support end 84 is comprised. When explaining the shape of the spring portion 83 more accurately, the front end of the fixing portion 82 is bent in a direction protruding from the inner surface of the connector housing 71, the front end is the inner surface of the connector housing 71 It is formed by bending in a direction approaching to.

The most protruding portion of the spring portion 83 is in contact with the contact portion 65 of the first terminal 60 in an elastically deformed state. The contact with the contact portion 65 is maintained by the restoring force of the spring portion 83.

The operation of the preferred embodiment of the present invention having such a configuration will be described.

Referring to FIG. 3, the coupling process between the first connector 30 and the second connector 70 will be described. First, the second connector 70 is inserted into the coupling space 52 in a state in which the tip of the second connector 70 faces the coupling space 52. Then, the partition wall 54 of the first connector 30 is inserted into the terminal hole 73 of the second connector 70. At this time, while the inclined surface 54 ′ formed at the tip of the partition wall 54 passes between the spring portions 83 facing each other, the spring portions 83 are pressed to elastically deform in a direction away from each other. Thus, the spring portion 83 is in contact with the contact portion 65 of the first terminal 60 seated on the partition wall 54 by a force to be restored.

As such, when the coupling of the second connector 70 and the first connector 30 is completed, the contact portion 65 of the first terminal 60 and the second terminal 80 inside the terminal hole 73 are completed. The spring portions 83 are in contact with each other and electrically connected.

On the other hand, the outer end of the terminal hole 73, the hook end 72 of the second connector 70 is seated on the seating jaw 56 of the inner housing 51 is walked. This state is shown in FIG. A gap is formed between the inner housing 51 and the outer housing 41 of the first connector 30 to surround the inner housing 51, and the inner housing 51 and the outer housing 41 have a first terminal ( Since only connected by 60, the inner housing 51 is possible to some extent flow. This is to prevent the vibration generated in the first substrate or the second substrate from being transmitted to each other on the first connector 30 and the second connector 70.

However, when the inner housing 51 flows beyond the limit, a deformation is applied to the first terminal 60 connecting the inner housing 51 and the outer housing 41 or the inner housing 51 or the outer one. Breakage may occur in the housing 41.

In order to solve this problem, in the present invention, a stopper 42 is placed at the corner of the outer housing 41 to regulate excessive flow of the inner housing 51.

That is, the flow preventing piece 45 of the stopper 42 covers a part of the upper edge of the inner housing 51 with respect to FIG. 2 to prevent the flow in the upper direction of the inner housing 51 (Z direction in FIG. 2). Regulate. In addition, the first restricting surface 46 of the flow preventing piece 45 is provided to be spaced apart from the end portion of the cover portion 58 of the inner housing 51 by a predetermined distance in the longitudinal direction of the inner housing 51 ( Flow in the X direction of FIG. 2 is regulated. In addition, the second restricting surface 47 of the flow preventing piece 45 is provided to be spaced apart from the outer surface of the second connector 70 in a state coupled to the inner housing 51 to the inner housing 51. To regulate the flow in the width direction (Y direction in FIG. 2).

As described above, in the present invention, the inner housing 51 and the second connector 70 are prevented from excessively flowing by the stopper 42. Therefore, deformation of the first terminal 60 due to excessive flow of the inner housing 51 is minimized.

In addition, in the present invention, the contact portion 65 of the first terminal 60 is brought into close contact with the partition wall 54 of the inner housing 51, thereby restoring the projecting structure in the coupling space 52, and thereby the second connector. In the coupling process with 70, the force applied to the first terminal 60 is minimized. That is, since the contact portion 65 of the first terminal 60 does not have a portion protruding in the coupling space 52, the vibration of the second connector 70 is concentrated on one side of the contact portion 65 by Deformation of the contact portion 65 or separation of the contact portion 65 from the terminal seating groove 55 'is prevented. Therefore, the contact point of the first terminal 60 and the second terminal 80 is well maintained.

In the present invention, since the contact portion 65 of the first terminal 60 extends straight in one direction and is completely fixed to the partition wall 54 of the inner housing 51, the first terminal 60 and Increasing the coupling area of the inner housing 51 to minimize the departure of the first terminal 60 in spite of the flow of the inner housing 51.

The scope of the present invention is not limited to the embodiments described above, but is defined by what is stated in the claims, and various changes and modifications can be made within the scope of the claims by those skilled in the art. It is self evident.
