[Industrial applications]

 The present invention relates to a structure for mounting a connector attached to an electric connection box or the like provided in an electric circuit of an automobile.

[0002]

[Prior Art]

In FIG. 5, a is an electric junction box, and a connector mounting bracket b is erected above the side wall a ₁ . The bracket b is provided with a pair of left and right engaging ribs b ₁ and b ₁ extending in the up-down direction to form a space S for accommodating a lock arm of a connector described later between the engaging ribs b ₁ and b _1. Thus, the main plate portion b ₂ is provided so as to be retracted inward, and the lock engaging portion b ₃ is formed on the main plate portion b ₂ .

Reference numeral c is a female through connector of a type in which an electric wire or a counterpart terminal fitting is axially penetrated, and a plurality of terminal accommodating chambers are formed and the terminal fitting is connected to the electric wire in advance. Is housed and locked. A mounting portion d that engages with the bracket b is integrally provided on the rear surface of the connector c, and the rear surface c of the connector c is mounted at the mounting portion d. ₁ From connection part d₁Board portion d provided with a space therebetween₂Engaging frame part d on the left and right ends of₃, D₃And the engaging rib b₁, B₁Groove d for receiving_Four, D_Four Is formed.

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and proposes a rattling prevention mechanism capable of fixing a connector to a mounting bracket so as not to make noise.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a pair of engaging ribs are provided on one side and a pair of engaging ribs are provided on the other side of a connector mounting bracket provided on a side wall portion of an electric connection box or the like and a rear surface of the connector. Is provided with a pair of engagement frames having engagement grooves formed therein, and the side wall portion is provided with a play preventing protrusion against which the back surface portion of the connector abuts.

[0007]

【Example】

 In FIG. 1, A is an electric junction box, on the side wall 1 of which a connector mounting bracket 2 is erected. The bracket 2 is provided with a pair of left and right engaging ribs 2a, 2a extending vertically, and a main plate portion is formed between the engaging ribs 2a, 2a so as to form a housing space S for the lock arm 3 of the connector B. 2b is provided to be retracted inward, and a lock engaging portion 2c is formed on the main plate portion 2b.

A mounting portion 4 that engages with the bracket 2 is integrally provided on the back surface of the female through connector B, and there is a space in the mounting portion 4 from the back surface of the connector B via the connecting portion 4 a. Engagement frame portions 4c, 4c are continuously provided at the left and right ends of the provided substrate portion 4b to form engagement grooves 4d, 4d for receiving the engagement ribs 2a, 2a. Further, the cantilevered lock arms 3 are continuously provided in the accommodation space S'between the engagement frame portions 4c and 4c via the rising base portion 3a.

On the side surface 1 of the electric junction box A, there are provided two ribs 5 for preventing rattling support ribs 5 extending in the extending direction of the engaging ribs 2 a of the bracket 2. Rattling prevention projections 5b, 5b are provided substantially parallel to the engaging ribs 2a through intermediate or tapered steps 5a, 5a (see FIG. 4).

In the above structure, when the connector B is pushed into the bracket 2 while being fitted in the engaging grooves 4d, 4d while receiving the engaging ribs 2a, 2a, the lower end portion 6 on the back surface of the connector B is supported for preventing backlash. The ribs 5 and 5 move loosely in contact with the ends thereof, and are fed outward by the taper-shaped step portions 5a and 5a in the middle, and also move up to the rattling prevention protrusions 5b and 5b by making strong contact with them. In this state, the protrusion 3b of the lock arm 3 engages with the lock engaging portion 2c of the main plate portion 2b, whereby the lock arm 3 is fixed in a state in which play is prevented (see FIGS. 2 and 3).

[0011]

[Effect of the device]

 As described above, the present invention provides a pair of engaging ribs on one side and an engaging groove on the other side for receiving the engaging ribs on the back surface of the connector mounting bracket and the connector provided on the side wall portion of the electric connection box or the like. Since there is provided a pair of engaging frames having the above-mentioned structure and the back side portion of the connector is in contact with the side wall portion, the connector is inclined at the side wall portion of the electric connection box or the like. Without backlash, it can be installed in an orderly manner, which facilitates installation work and saves space.
