Description

Terminal part Technical Field The present invention relates to a terminal fitting. Background The female terminal part disclosed in patent document 1 is provided with an elastic contact piece on a side wall of a tubular connection portion. The elastic contact piece can elastically deform to the inner side and the outer side of the tubular connecting part. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2013-25988 Disclosure of Invention Problems to be solved by the invention The elastic contact piece of the female terminal fitting of patent document 1 is exposed to the outside of the tubular connection portion. Therefore, in the structure of patent document 1, it is necessary to cover the elastic contact piece with another member. The present invention has been made in view of the above circumstances, and an object thereof is to provide a terminal fitting capable of protecting an elastic contact portion without increasing the number of parts. Means for solving the problems The terminal part of the present invention comprises: A square cylindrical box section having an insertion opening into which the counterpart terminal is inserted; An elastic contact portion elastically deformable to be exposed to an outer surface of the case portion, and And a cover part integrally formed with the case part and covering the elastic contact part from the outside. Effects of the invention According to the structure of the present invention, the elastic contact portion can be protected without increasing the number of parts.

Detailed Description (Description of embodiments of the invention) First, an embodiment of the present invention will be described. (1) A terminal component is provided with: A square cylindrical box section having an insertion opening into which the counterpart terminal is inserted; An elastic contact portion elastically deformable to be exposed to an outer surface of the case portion, and And a cover part integrally formed with the case part and covering the elastic contact part from the outside. (1) Since the cover portion is integrally formed with the case portion, the elastic contact portion can be covered without increasing the number of components. (2) The terminal fitting according to (1) further comprising a folded portion folded back outward from an opening edge portion of the insertion port, The folded-back portion has a guide surface for guiding the counterpart terminal toward the insertion port, The covering portion is connected to the folded-back portion. (2) The folded portion of the terminal part has both the function of guiding the opposite terminal and the function of supporting the cover portion, so that the structure of the terminal part can be simplified as compared with the case where these functions are provided separately. (3) In the terminal fitting of (2), an inclined portion having a guiding surface extending forward of the guiding surface in the opening direction of the insertion port is connected to the opening edge portion, and the counterpart terminal is guided to the insertion port. (3) The terminal part of the terminal can be inserted into the insertion opening more easily by the inclined part. (4) In the terminal fitting according to (3), the covering portion is connected to the pair of folded-back portions, The inclined portion is disposed so as to be sandwiched between the pair of folded-back portions. (4) The pair of folded portions sandwich the inclined portion, and the inclined portion has a guiding surface extending forward in the opening direction than the folded portion, so that the opposite terminal is guided to the insertion opening without being deflected, and can be guided with good balance. (5) In the terminal fitting according to any one of (1) to (4), the elastic contact portion is elastically deformable to the outside of the case portion, An allowable space is formed between the cover portion and the outer surface. (5) The terminal part of the box part can pass through the allowable space without preventing the elastic contact part from being elastically deformed to the outside of the box part.
