Description of the Invention (/) Field of the Invention The present invention relates to a male connector (receptacle) which is pluggable and pluggable. BACKGROUND OF THE INVENTION Figures 3 and 4 show examples of a conventional male connector P and a female connector R. This male connector P 'has a fitting part 2' which can be fitted into the recess 21 which is open in the front opening of the female connector body 20 of the female connector R, and which can be inserted and removed, and a protruding part 2 ' The front male connector body Γ. In addition, a plurality of signal posts (not shown) are provided on the bottom surface of the recess 21 of the female connector body 20 to support the fitting recess 5 'which can be inserted into the fitting recess 2' of the fitting portion 2 '. The protruding portion 22 is provided with a plurality of signal contacts (not shown) in contact with the contact portion of the signal pillar at the same time in the fitting recess 5 ′. However, in the above-mentioned conventional example, as shown in FIG. 4, when the male connector P ′ is inserted and removed from the female connector R, the male connector P ′ needs to be inserted and removed in an inclined manner, and the male connector is simultaneously connected. The side wall 2c 'of the fitting portion 2' of the connector P 'interferes with the protruding portion 22 of the female connector R. Thus, the insertion and removal of the male connector P' causes the side wall 2c 'of the fitting portion 2' to be damaged. doubt. In view of the above circumstances, an object of the present invention is to provide a male connector so that it is difficult to cause discomfort such as breakage when the female connector is inserted and removed at an angle. Description of the invention In order to achieve the above-mentioned object, the first invention of the scope of patent application is to propose a male connector. The male connector is provided with and can be fitted into a female connector. The paper size is applicable to Chinese National Standard (CNS) A4.

Description of the invention (>) The recess of the front opening of the female connector body The inner fitting portion and the male connector body protruded in front of the fitting portion, and a plurality of signal pillars protruding from the bottom surface of the recessed portion of the female connector body are provided to support the fitting recessed portion of the fitting portion. And the projecting part can be inserted freely, and a plurality of signal contacts that are in contact with the contact part of the signal pillar are simultaneously provided in the fitting recess. The characteristic of this male connector is that the lateral dimension near the opening end of the fitting recess is greater than The horizontal dimension inside the fitting recess. In this way, when the female connector is inserted and removed obliquely, the side wall of the fitting portion near the opening end of the fitting recess does not interfere with the protruding portion of the female connector, and it is difficult to cause unsuitable phenomena such as breakage of the fitting portion. The invention according to the second patent application scope is characterized in that, in the first invention within the patent application scope, the inner side surface near the opening end of the fitting recess is formed with an inclined surface inclined outward. In this way, when the female connector is inclinedly inserted and removed, the contact surface located near the opening end of the fitting recess is in contact with the protruding portion of the female connector, and the protruding portion is guided by the inclined surface to correct the fitting. The inclination angle between the recessed portion and the protruding portion prevents the interference between the side wall of the fitting portion and the protruding portion of the female connector near the opening end of the fitting recessed portion, and v is unlikely to cause unsuitable phenomena such as breakage of the fitting portion. Item 3 of the scope of patent application, among the items 1 and 2 of the scope of patent application, has the feature that the thickness of the side wall of the fitting portion near the open end of the fitting recess is thicker than the thickness of the side wall located inside the fitting recess. . This can increase the strength of the side wall of the fitting portion near the opening end of the fitting recess portion, and it is difficult to cause unsuitable effects such as breakage of the fitting portion.

Description of the invention (b) (please first read Please fill in this page again on the side of the surface.) A recessed recess 5 is provided at the opening of the surface, and a plurality of recessed recesses 5 are arranged in parallel on the inner wall surface of the side wall 2a on one side opposite to the thickness direction of the recessed recess 5. A trench having a relatively narrow width from the bottom surface to the front surface of the fitting portion 2 is embedded with a contact portion 6a of the signal contact 6 in each trench. That is, the contact portions 6 a of the plurality of signal contacts 6 are exposed and arranged along the lateral direction of the side wall 2 a in the fitting recess 5, and when the protrusion 22 of the female connector R is fitted in the fitting recess 5, The contact portions of the plurality of signal pillars supporting the protruding portion 22 are in conduction with each other. The rear end of each signal contact 6 is electrically connected to a signal cable 51 located in the male connector body 1. In addition, on the outer wall surface of the side wall 2b on the other side opposite to the thickness direction of the fitting recessed portion 5, a pair of protruding strips 7 are protruded along the insertion and removal direction toward the recess 21 of the female connector body 20. 7 ′, and the fitting groove 21 a formed on the inner wall surface of one of the sides of the depression 21 may be concave and convex with each other (refer to FIG. 2). That is, the male connector p can be connected to the female connector R only when the protruding strip 7 and the fitting groove 21 can be mated oppositely. In this way, reverse insertion of the female connector R and the male connector P can be prevented.

Description of the invention (^) It is inclined outward, so it is located at The lateral dimension near the opening end of the fitting recess 5 is larger than the lateral dimension inside the fitting recess 5. In addition, in the conventional example, the thickness of the side wall 2c 'of the fitting portion 2' is uniform in the depth direction of the fitting recess 5 ', so that the strength near the opening end of the fitting portion 2' is insufficient. . Therefore, in this preferred embodiment, an expansion protrusion 8 is designed to expand outward along the lateral direction of the fitting recess 5 on the portion near the open end of each side wall 2c, 2c that is inclined outward, and expands here. In the protruding portion 8, the thickness of the portion near the open end of the side wall 2c is thicker than the thickness of the portion inside the fitting recess 5, so as to greatly increase the strength of the portion near the open end of the side wall 2c. However, referring to FIG. 2, when the male connector P is mated to the female connector R, the male connector P is inclined so that the side wall 2 c of the fitting portion 2 located near the opening end of the fitting recess 5 is not inclined. , 2c interferes with the protruding portion 22 of the female connector R, and it is difficult to cause unsuitable phenomena such as breakage of the fitting portion 2. In addition, the inner surface near the opening end of the fitting recess 5 is formed with an inclined surface 2d which is inclined outwardly, so that the contact surface near the opening end of the fitting recess 5 is temporarily aligned with the protrusion 22 of the female connector R. The protrusion 22 is brought into contact with the inclined surface 2d to correct the inclination angle of the fitting recess 5 and the protrusion 22. In addition, the expansion protrusion 8 can be used to thicken the portion near the open end and increase the strength so that, for example, when the side wall 2c interferes with the protrusion 22, the fitting portion 2 (side wall 2c) is hardly damaged. In addition, the rear side of the expansion protrusion 8 is located on the outside of the side walls 2c, 2c.
