Abstract

[Problem] To provide a connector that can stably hold the color. [Solution] The connector 10 comprises a resin connector housing 20 having a collar mounting hole 24, and a cylindrical metal collar 30 that is fitted into the collar mounting hole 24. The collar 30 has a recessed portion 31 on its outer circumference that repeats in the axial direction, and is press-fittable into the collar mounting hole 24. The collar mounting hole 24 has an inclined receiving portion 25 at the end of the collar 30 in the press-fitting direction, with an enlarged inner diameter to accommodate debris scraped off by the recessed portion 31.

Description

This disclosure relates to connectors. Conventionally, connectors have a resin connector housing with a collar mounting hole, and a cylindrical metal collar that is fitted into the collar mounting hole. The collar mounting hole has a locking portion that protrudes radially inward and extends circumferentially, and a notch cut out of the locking portion. The collar has a flexible locking piece that engages with the locking portion, and an anti-rotation portion housed in the notch (see, for example, Patent Document 1). This connector is said to ensure reliable mounting of the collar into the collar mounting hole and secure prevention of the collar's rotation. Such connectors are fixed to the object by a bolt that passes through the collar. Japanese Patent Publication No. 2013-45554 Figure 1 is a perspective view of a connector in one embodiment.Figure 2 is a partial cross-sectional view of a connector in one embodiment.Figure 3 is a partially exploded cross-sectional view of a connector in one embodiment. [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The connector disclosed herein is [1] A connector comprising a resin connector housing having a collar mounting hole, and a cylindrical metal collar that is fitted into the collar mounting hole, wherein the collar has an axially repeating uneven surface and is press-fittable into the collar mounting hole, and the collar mounting hole has a receiving portion at the end in the press-fitting direction of the collar, the inner diameter of which is enlarged to accommodate debris scraped off by the uneven surface. According to this configuration, the collar has a textured surface with repeated axial irregularities on its outer surface, yet it can be press-fitted into the collar mounting hole. Therefore, compared to a configuration without these irregularities, the collar is held more stably in the mounting hole. In other words, the collar is less likely to shift axially or tilt relative to the mounting hole. Furthermore, the collar mounting hole has a larger inner diameter at the end in the press-fitting direction of the collar to accommodate the debris scraped off by the textured surface, thus reducing the possibility of debris overflowing from the collar mounting hole. Specifically, if the collar mounting hole has a constant inner diameter and lacks a storage area, there is a risk that debris scraped off by the textured surface during press-fitting may overflow from the collar mounting hole and become trapped around the opening due to the viscosity of the resin; this can be prevented. [2] In the above [1], the housing portion may be an inclined housing portion in which the inner diameter gradually increases toward the opening end of the collar mounting hole. With this configuration, the housing section is an inclined housing section whose inner diameter gradually increases towards the opening end of the collar mounting hole. Therefore, when the collar is pressed in, the debris scraped off by the uneven surface easily gets caught between the collar and the inclined housing section. As a result, the amount of debris spilling out of the collar mounting hole is further reduced. [3] In the case of [1] or [2] above, the collar mounting hole may have an inclined guide portion at the end opposite to the press-fitting direction of the collar, where the inner diameter gradually increases toward the open end of the collar mounting hole in order to guide the collar. According to this configuration, the collar mounting hole has a sloping guide portion at the end opposite to the direction of collar press-fitting, where the inner diameter gradually increases towards the opening end of the collar mounting hole to guide the collar. This facilitates positioning the collar during press-fitting into the collar mounting hole. [4] In the above [1], the housing portion is an inclined housing portion whose inner diameter gradually increases toward the open end of the collar mounting hole, and the collar mounting hole has an inclined guide portion at the end opposite to the press-fitting direction of the collar, whose inner diameter gradually increases toward the open end of the collar mounting hole in order to guide the collar, and the inclined housing portion and the inclined guide portion may have the same shape. According to this configuration, the housing section is an inclined housing section whose inner diameter gradually increases towards the opening end of the collar mounting hole. Therefore, debris scraped off by the uneven surface during collar press-fitting is more easily trapped between the collar and the inclined housing section. This reduces the likelihood of debris overflowing from the collar mounting hole. Furthermore, the collar mounting hole has an inclined guide section at the end opposite to the collar press-fitting direction, which gradually increases in inner diameter towards the opening end of t
