A conventional electrical connector of this type has a structure as shown in FIG. That is, 1 is an electrical connector consisting of a male housing 2 and a female housing 3, and inside the male housing 2, a plurality of male terminals 5 connected to a wire harness 4 are arranged. Also, inside the female housing 3, a plurality of female terminals 6 are arranged, which are connected to the wire harness 4 and to the male terminals 5. Furthermore, a locking piece 2 is provided on the male housing 2.
a is formed, and a locking pawl 3a is formed on the female housing 3, and when both housings 2 and 3 are completely fitted, the locking piece 2a and the locking pawl 3a are engaged. The structure is such that both housings 2 and 3 are prevented from coming off. Reference numeral 7 denotes a waterproof packing made of rubber or soft resin that is interposed under pressure between the male housing 2 and the female housing 3.
Also, moisture is prevented from entering the female terminal 6.

れるといつた問題点があつた。 However, in such an electrical connector having a conventional structure, the male housing 2 and the female housing 3 are made of thermoplastic resin material, and there is a surface inside the housings 2 and 3 to improve waterproofness. Since the electrical connector 1 has a structure in which the high-pressure gasket 7 is housed, when the electrical connector 1 is used in a high-temperature location, the resin housing 2 or 3 creeps (changes over time), and this causes the opening of the male housing 2 to close to the seal 7, especially in this conventional electrical connector 1.
Due to the surface pressure caused by this, the housings 2 and 3 were deformed into a floppy shape, making it impossible to smoothly attach and detach the housings 2 and 3, and the tightness of the seal 7 was reduced, resulting in weakened waterproof properties.

On the outer peripheral surface of the fitting cylinder part 2c of the male housing 2,
Since it is covered with a metal reinforcing ring 10, the reinforcing action of this reinforcing ring 10 provides
It is possible to effectively prevent the deformation of the housing 2, particularly the fitting tube portion 2c, by pressure and heating, and deformation over time, thereby preventing deterioration of the fitting performance of both the male and female housings or the waterproof performance during the fitting. Further, according to this embodiment, the metal reinforcing ring 10 can be attached to the housing 2 by a simple operation such as fitting the reinforcing ring 10 to the outer circumferential surface of the fitting cylinder portion 2c. The ease of assembly of the connector is also good.
