Abstract

PURPOSE: To smoothly perform fitting operation of a connector by increasing the strength of a hood part. CONSTITUTION: In a male housing 1, a hood part 3 having nearly a square pillar form for closely fitting into a counterpart female housing on the inside is provided. One long-side part of the hood part 3 is formed in double-wall structure in which an external wall 7 is formed outside an inner wall 5 through an air gap 6. In the case of the double-wall structure, the increase of strength is achieved without an inward warp at the time of molding. Since a plate-form bracket is interposed in a central part in the direction of the width of a double- wall part 8, a mounting groove 10 is formed. The fixed width of the central part of the mounting groove 10 in the direction of the width of the external wall 7 is cut off, namely, the central part is formed so as to have the cross section of a nearly T-shaped form by providing a single wall in a part of the double wall. Also, the part of the mounting groove 10 is strengthened.

The feature is that the structure is formed by the above.

[0009]

According to the first aspect of the present invention, the hood portion has a double wall structure, so that the strength thereof is increased, and the hood portion is molded into a regular shape without causing inward warping. That is, since the hood portion is formed into a regular shape, the operation of fitting the housing of the mating connector is performed smoothly, and the hood portion is strengthened to make it difficult to deform. It is prevented from being fitted in the state. In the invention of claim 2, since the mounting groove is formed by providing a single wall on a part of the double wall, the strength of the mounting groove portion can be increased.

[0010]

According to the first aspect of the present invention, when the housing of the mating connector is fitted in the hood portion, it can be fitted smoothly without twisting, so that the fitting operation is efficient. There is an effect that it can be performed well and that the terminal fitting can be prevented from being deformed or contact failure being caused. According to the second aspect of the present invention, when the connector is attached to the fixing portion using the bracket, the effect that the connector can be attached stably without rattling is obtained.
