New description: [New technical field] This creation is about an electrical connector, especially an electrical connector that can be inserted into an electronic card. [Prior Art] U.S. Patent No. 6,672,499 discloses an electrical connector disposed on a circuit board for electrically connecting an electronic card, the electrical connector including an insulative housing, a slot opening forward from the insulative housing, and a plug A latching arm is formed on the two ends of the slot from the two ends of the insulative housing. The upper and lower sides of the slot are respectively arranged with conductive terminals, and the contact ends of the conductive terminals respectively extend into the slot to contact the conductive pads on the electronic card. In order to facilitate the insertion and removal of the electronic card from the electrical connector, inclined upper and lower guiding sections are respectively disposed on the upper and lower side walls of the slot, and the extending directions of the upper and lower guiding sections are parallel to each other and to the electronic The card is inserted in the same direction. When the electronic card is inserted, the upper and lower guiding segments can guide the electronic card to the insertion position, where the corners of the upper and lower sides of the electronic card are respectively in contact with the rear side wall and the lower side wall of the slot, during the rotary pressing process The corner of the upper side of the electronic card may scratch the side wall behind the slot. When the electronic card is rotated and released, the corner of the lower side of the electronic card may scrape the horizontal portion of the rear end of the lower side wall of the slot, and the electronic card is rotated to the unplugged position, where the electronic card plane is substantially parallel to the upper and lower guiding segments. If the external force acts in a direction perpendicular to the upper and lower guiding sections, the electronic card may be attached to the upper guiding section and the lower guiding section is the supporting surface to tear the insulating body into two pieces, thereby electrically connecting Damaged. In addition, during the rotation insertion and release of the electronic card, since the upper and lower corners of the electronic card may scratch the side wall of the slot, scraping debris is generated, and when the electronic card is reinserted, the scraping may be present at the conductive terminal. The contact end is between the conductive pad of the electronic card, thereby causing poor conduction of the electronic card. Based on the prior art described, it is indeed necessary to retrofit existing electrical connector combinations to overcome the deficiencies of the prior art. [Creation Content] The purpose of this creation is to provide an electrical connector that can be used safely. The purpose of the present invention is achieved by the following technical solutions: the present invention provides an electrical connector including an insulative housing and a terminal fixed to the insulative housing, the insulative housing having a slot open to the front, the slot There are upper and lower side walls, wherein the lower side M309787 wall has an arcuate section. Compared with the prior art, the electrical connector assembly of the present invention has the following beneficial effects: Since the lower side wall of the insulating body slot has an arc segment, the electronic card can be smoothly guided out when being released from the electrical connector, Conducive to the safe use of electrical connectors. [Embodiment] The first to third figures show a preferred embodiment of the present invention, an electrical connector that electrically connects an electronic card 6 that is obliquely inserted and rotatably mounted thereto On a circuit board (not shown). The electrical connector has an insulative housing 1 and a latching arm 11 extending forwardly from the insulative housing. The insulative housing is provided with a slot 10 that is open to the front and a conductive terminal that is disposed on both sides of the slot and is fixed to the insulative housing. 20. At the free end of the latching arm 11, a latching block 12 and a positioning block 13 projecting inward are provided. The conductive terminal 20 includes a contact end 21 that extends into the slot 10 and a solder end 22 that extends out of the outer side of the insulative housing 10. The electrical connector 1 is pre-positioned on the circuit board by a positioning post (not shown) on its bottom side, and then the soldering end 22 of the conductive terminal is soldered to a corresponding solder pad (not shown) on the circuit board. The electrical connector is fixed. The electronic card is obliquely inserted into the slot 10 and is rotationally pressed into a latching position substantially parallel to the circuit board. At this position, the rear end of the electronic card contacts the contact end 21 of the conductive terminal 20, respectively, and the front end of the electronic card is buckled. The latching action of the block 12 maintains the positioning in the up and down direction, and the positioning of the positioning block 13 and the notch (not shown) on the electronic card maintains the positioning of the electronic card in the front-rear direction, so as to guide the insertion of the electronic card, the holding block The guide surface 15 is inclined from top to bottom. Referring to the second figure, the slot 10 that opens forward on the insulative housing 1 includes an upper side wall 16, a lower side wall 17, and a side wall 18 that connects the upper and lower side walls. The upper side wall 16 is composed of an arcuate section 160 that protrudes from the top to the side of the front side toward the slot side and a horizontal section 161 of the rear end. The lower side wall 17 is defined by the horizontal section 170 of the front end and the rear end from the front to the rear. An arcuate section 171 projecting from the upper side toward the lower side of the side wall is formed. The rear side wall 18 defines a relief groove 180 which is recessed toward the rear side near the upper side wall. The escape groove is formed with a contact portion 181 at an intermediate portion of the rear side wall. At the beginning of insertion of the electronic card into the slot 10, the arcuate section 160 at the front end of the upper side wall 16 and the arcuate section at the rear end of the lower side wall 17 can guide the insertion of the electronic card into contact with the contact portion 181 of the rear side wall 18, the portion of the electronic card The structure is located in the escape slot 180. During the rotation of the electronic card to the latching position, the electronic card is kept in contact with the contact point 181 to avoid the slot 180 from being scratched by the sharp upper side corner of the electronic card. M309787, because the curved section 171 at the rear end of the lower side wall 17 is inclined from the top to the bottom in the front-rear direction, the electronic card is released from the holding position and the rotation of the electronic card is guided to the arc by the external force. It avoids the danger of tearing in the electronic connector, which is beneficial to the spear of the electrical connector. Secondly, avoiding the sharpness of the electronic card in the process of rotation, the same as the 4 can also be ^ ^ 卞 sharp sharp side buckle angle The rear side wall 18 is partially scraped. ,,,, not mentioned, this creation has indeed met the requirements of the new patent, | 侬牛捭 φ & ϋ , .
