Abstract

An electrical connector includes a dielectric body and a plurality of terminals each having a base portion held within the dielectric body. Each terminal has a contact portion positioned above the dielectric body when the terminal is not pressed down and a free end on an elastic arm portion extending from the contact portion, located within the dielectric body. The terminal has a curved section adjacent to the free end of the elastic arm portion, and the curved section slides on the base portion and moves inward when the terminal is depressed. The dielectric body has protrusions and each terminal has wing portions engageable with respective protrusions. The wing portions and the protrusions can prevent the terminals from being accidentally moved when the terminals are not depressed.

New description: [New technical field] This creation is about an electrical connector. [Prior Art] An electrical connector having the configuration shown in Fig. 1 is generally used for a mobile electronic device and is used for a connection-battery pack. The electrical connector has a terminal η, the terminal u is held by the insulating housing 12 and has a contact portion (1), wherein the contact portion protrudes from the top surface of the insulating housing 12 to contact the pad of the electronic device 13 (PadS) 13 After the electronic device 13 is connected to the electrical connector ι, the electronic device 13 is adjacent to the top surface of the insulating housing 12, and the contact portion lu is elastically pressed into the insulating housing 12. The contact portion U1 includes a flat bottom portion. The shape, such a large space is required to accommodate the large space of the contact portion, which makes the insulating case 匕 thicker and wider. However, the electrical connector of the thick and wide insulating housing 12 cannot meet the needs of small electronic devices. When the terminal 1.1 is depressed, the contact portion ln does not contact any portion of the electrical connector 丨. The terminal of this design is relatively soft, so that a small contact force is applied to the pad 1 of the electronic device 13, resulting in a large contact resistance. In some designs, the contacts of the terminals need to be properly separated from the insulative housing. Under such a trick, when an electronic device is connected to an electrical connector, the contact portion needs to be moved over a long distance before it comes into contact with the insulating housing. In some designs, when the contact portion is not pressed, the tip end of the contact portion is exposed outside the insulating case. If the electrical connector is not properly used, the exposed tip may come into contact with the insulating body, causing damage to the terminal. M440555 In order to avoid the problems caused by the large road, in some conventional electrical connectors, the vertical extension is used to allow the tip to be inside the insulating case without the contact being pressed. However, such electrical connectors require a thick insulated housing to accommodate the pressed contacts and the vertically extending sections and are therefore not suitable for use in small devices. It is known that the terminal 11 shown in Fig. 1 has a lower concave section 112. The tip end portion 113 is located in the depressed portion 112 when the contact portion iH is pressed down. The depressed section 112 blocks the movement of the tip end portion 113, so that the terminal u is not suitable for the contact portion 111 which can be moved over a long distance. [New content] In view of the deficiencies of the aforementioned conventional electrical connectors, a new electrical connector has been proposed. According to an embodiment of the present invention, an electrical connector includes an insulative housing and a plurality of terminals. The insulating body has a substantially rectangular shape.

In the two adjacent terminal slots, the slot of the terminal slot is located on the front surface, and the slot of the other terminal slot is located on the rear surface. A plurality of stop blocks correspond to a plurality of groove walls. Each stop block projects from a corresponding slot wall. Each of the terminals includes a base, a soldering portion, a first test portion, a first elastic arm portion, a contact portion, a second curved portion, a -5-M440555, a second elastic arm portion, and two wings. The base portion is formed to be fixed to the corresponding terminal. The connecting portion extends from a side edge of the slot of the base portion close to the corresponding terminal slot to the corresponding slot of the terminal slot. The first curved portion extends from a side edge of the base away from the slot of the corresponding terminal slot. The first curved portion includes a convex side, and the convex side of the first curved portion faces away from one of the slots of the corresponding terminal slot

Damaged as. Further, as shown in Fig. 7, when the terminal 22 is moved laterally, the wing portion 228 will contact the corresponding stop block 216, so that the position of the terminal 22 in the notch 2151 can be stabilized. Referring to Figure 4, the contact portions 225 of the terminals 22 can be arranged in two rows, with the contact portions 225 of the rows insulating the front surface 213 of the body 21 and the contact portions 225 of the other row being adjacent the rear surface 214 of the insulating body 21. This two-row design allows the electrical connector 2 to be more stable and stable under continuous load. Referring to Figs. 9 to 12, when the contact portion 225 of the terminal 22 is started to be depressed by the electronic device 4, the electronic device 4 is elastically supported by the first elastic arm portion 224. When the contact portion 225 of the terminal 22 is further depressed, the curved surface 2273 of the second resilient arm portion 227 contacts the base portion 221. At this point, the electronic device 4 is elastically supported by the first elastic arm portion 224 and the second elastic arm portion 227. After the contact, the curved surface 2273 starts to slide on the base portion 221, and the moving direction of the end 2271 of the second elastic arm portion 227 changes. The end 2271 of the second resilient arm portion 227 is then moved away from the slot 2151 of the corresponding terminal slot 215 by the guiding of the base portion 221. After the contact portion 225 of the terminal 22 is completely depressed, the second resilient arm portion 227 extends into the corresponding terminal slot 215 'and is seated on the base portion 221'. The terminal is designed to be suitable for an electrical connector having a long-distance moving contact portion. 'And there is no need to use a thick insulating body. to accommodate the second resilient arm portion 227. It is to be noted that with such a terminal design, the thickness of the insulating body 21 can be further reduced, so that the electrical connector 2 which is thinner than the conventional electrical connector can be obtained. • 12· M440555 When the contact portion 225 of the terminal 22 is pressed down, the second resilient arm portion 227 abuts against the base portion 22 to cause the contact portion 225 to apply an additional contact force to the corresponding pad 41 of the electronic device 4 ^ additional contact force The contact resistance between the contact portion 225 and the pad 41 can be reduced. Fig. 8B is a schematic cross-sectional view showing an embodiment of the present invention. The terminal 22 is an insulative housing 21 housed in the electronic device 2. Referring to Figures 8A and 8B, the electronic device 2 can provide a relatively large contact force of the electronic device as compared with a similar conventional electrical connector. The terminal 22· includes a first C-shaped structure 220 and a second C-shaped # structure 229, wherein one end of the first C-shaped structure 220 is connected to one end of the second c-shaped structure 229. Each of the first c-shaped structure 220 and the second C-shaped structure 229 includes a C-shaped portion. The C-shaped portion includes a & convex side, wherein the convex sides are generally convexly projecting in opposite directions. The first C-shaped structure 220 includes a base portion 221 'a first curved portion 223 and a first resilient arm portion 224. The base 221 is formed to be fixed to the corresponding terminal groove 215. The first bent portion 223 extends from the edge of the base portion 221 away from the notch 2151 of the corresponding terminal groove 21 5 . The first curved portion 223 includes a convex side, and the convex side of the first curved portion 223 faces away from the notch 2151 of the corresponding terminal groove 215. One end of the first bent portion 223 faces the notch 2151 of the corresponding terminal groove 215. The first resilient arm portion 224 extends from the first curved portion 223 and in a direction upward of the notch 2151 of the corresponding terminal groove 215. The second C-shaped structure 229 includes a contact portion 225, a second curved portion 226, a second resilient arm portion 227, and two wings 228. The contact portion 225 is formed at one end of the first elastic arm portion 224. The second curved portion 226 extends from the contact portion 225. The second curved portion 226 includes a convex side, the convex side of the second curved portion 226 faces an obliquely upward direction, and the end 2261 of the second curved portion 226 faces away from the notch 2151 of the slot 215 of the corresponding terminal-13-M440555. One direction. The second resilient arm portion 227 extends from the second curved portion 226 in a direction away from the notch 2151 of the corresponding terminal slot 215. The two wing portions 228 are respectively formed at opposite side edges of the second elastic arm portion 227 and are adjacent to one end 2271 of the second elastic arm portion 227. The second C-shaped structure 229 may further include a section 2272 adjacent to the end 2271 of the second resilient arm 227, the section 2272 being curved toward the first resilient arm 224, thus forming a curved surface 2273 toward the base 221 . In one embodiment, the curved surface 2273 is separated from the base 221 . In another embodiment, the curved surface 2273 contacts the base 221 when the contact portion 225 of the second C-shaped structure 229 is not depressed. The first C-shaped structure 220 and the second C-shaped structure 229 each contribute contact force to the electronic device. When the contact portion 225 of the second C-shaped structure 229 is pressed by an electronic device and the curved surface 2273 does not touch the base portion 221, the pressure under the contact portion 225 causes the first C-shaped structure 220 to be significantly deformed, thereby generating a pair of electronic devices. The contact force; and after the curved surface 2273 contacts the base 221, the second C-shaped structure 229 is simultaneously deformed, thereby generating an additional contact force to the electronic device. From this, it can be seen that the terminal 22' can provide a larger contact force than a terminal having only a C-shaped structure. In an embodiment, the curved surface 2273 can contact the base 221 when the contact portion 225 of the second C-shaped structure 229 is not depressed. This design produces a similar preloading effect, allowing the terminal 22' to be more rigid when the terminal 22' comes into contact with the electronic device. Referring to FIG. 10, the insulative housing 21 can further include two positioning posts 217 and 218 extending downward from the lower surface 212 of the insulative housing 21 by M440555. Correspondingly, the printed circuit board 3 can include two openings 32 and 33. The two positioning posts 21 7 and 21 8 can have different lateral dimensions ' and the two openings 32 and 33 also have different lateral dimensions correspondingly so that the electrical connector 2 can be properly secured against the presence of the connector. As shown in FIG. 8A, in another embodiment, when the contact portion 225 is not depressed, the curved surface 2273 of the second resilient arm portion 227 of the corresponding terminal 22 can be adjacent to the corresponding base portion 221, so that when the electronic device contacts When the portion 225 is pressed down, the second elastic arm portion 227 can abut against the base portion 221. The contact between the curved surface 2273 and the base 221 can restrain the terminal 22' such that the contact portion 225 can be securely attached to the mounted electronic device without the thermal vibration of the electrical connector 2, allowing the contact portion 225 to be separated from the mounted electronic device. This robust connection between the contacts and the electronics ensures a smooth power transfer. Referring again to the terminal 11 shown in FIG. 1, when the contact portion 111 is pressed down, the tip end portion 113 of the terminal 11 does not make any contact, so the terminal 11 is not completely restrained, and the contact portion lu of the terminal 11 cannot be stably and The corresponding contact 131 is in contact, so that the contact portion in the terminal η may be separated from the pad 131 of the electronic device 13. An unreliable contact between such a terminal η and the pad 131 may cause instability in current transmission. In addition, the terminal 11 has a U-shaped curved section, and has a first curved portion 223 and a second curved portion 22 compared to the ground terminal 22. When the contact portion η of the terminal turns is pressed, the u-shaped curved portion is deformed, and thus A contact force is generated between the contact portion U1 and the pad 131. On the other hand, when the contact portion 225 of the terminal 22 is pressed down, the first bent portion 223 is deformed, thereby generating a contact force. Further, when the curved surface is in contact with the base portion 221, the second curved portion 226 is deformed to increase the contact force. Therefore, the terminal 具有 having the first bent portion 223 and the second bent portion 226 can generate a larger contact force than the terminal u having only a single u-shaped bent portion. Also because the electrical connector 2 containing the terminal 22 can be used to transmit large currents. Further, in the conventional electrical connector 1, the tip end portion 113 of the terminal turns into contact with the blocking member 14, thereby preventing the terminal π from being pulled out. The tip end portion 113 is short and therefore relatively rigid, so that the tip end portion 113 is easily damaged when a large pulling force is applied. On the contrary, since the curved surface 2273 of the second elastic arm portion 227 of the terminal 22 is close to the corresponding base portion 221 ', the second elastic arm portion 227 is longer and therefore more elastic, so when the second elastic arm portion 227 is in the section 2272 When the stop block 216 is touched, the zone segment 2272 is not easily damaged. In summary, the embodiment of the present invention discloses an electrical connector comprising an insulative body and a plurality of terminals. When the terminals are not depressed, the ends of the terminals are located in the insulating body so that the ends of the terminals do not collide with the insulating body. Each terminal includes a base and a resilient arm portion, wherein the ends of the terminals are located on the resilient arms. The resilient arms extend obliquely and have a curved surface near the end. When the contact portion of the terminal is pressed down, the curved surface slides on the base portion, and the elastic arm portion gradually moves toward the base portion at the same time. Finally, the elastic arm is housed in the insulating body. Because of this feature, the electrical connector can be smaller and thinner than conventional electrical connectors. The contact between the curved surface and the base can align the pads on the electronic device at the contact portion of the terminal to generate an additional contact force, thereby reducing the contact resistance between the contact portion and the pad. The insulative housing has a stop block, each terminal / has a wing portion, and the wing portion can touch the stop block. The wings and stops prevent accidental movement of the terminals that are not depressed. The technical content and technical features of this creation have been disclosed above, but those skilled in the art may still make various modifications and modifications based on the teachings and disclosures of this creation. 16- M440555 Therefore, the scope of protection of the present invention is limited to those disclosed in the embodiments, and the present invention is intended to cover various alternatives and modifications without departing from the scope of the invention.
