Abstract
Description
[Technical field]
[0001] The utility model relates to an electric connector and an electric connection component, in particular to an electric connector and an electric connection component which can be detachably and stably contacted with a flat conductive piece. [Background technology]
[0002] The existing FPC (flexible printed circuit) is electrically connected to the circuit substrate by directly inserting the FPC into the slot-type socket connector on the circuit substrate, so that the gold finger of the FPC directly contacts the spring arm terminal of the socket connector to achieve electrical connection. However, the spring arm terminal is prone to elastic attenuation after being welded at high temperature and then returned to the furnace, resulting in unstable contact between the spring arm terminal and the FPC.
[0003] Another way is to replace the socket connector on the circuit board with a pin terminal, but the pin terminal cannot directly and stably contact the FPC. Generally, the sleeve terminal needs to be riveted on the FPC first, and then the FPC with the riveted sleeve terminal is assembled into a plug housing to form a plug connector, so that the plug connector and the socket connector are docked, and the sleeve terminal contacts the pin terminal to achieve electrical connection between the FPC and the circuit board. However, the riveting process requires expensive riveting equipment, which significantly increases production costs; and after riveting, the sleeve terminal and FPC are difficult to disassemble and the FPC has been pierced. Once a sleeve terminal or FPC is defective, the remaining good sleeve terminals or FPCs can only be scrapped together and cannot be recycled for reuse, resulting in waste. [Utility Model Content]

[0041] Figures 1 to 3 The electrical connector 1 of the utility model comprises an insulating body 11, a plurality of conductive terminals 12 contained in the insulating body 11, and a locking member 13. In this embodiment, the electrical connector 1 and two flat conductive members 2 form an electrical connection assembly; in other embodiments, the electrical connector 1 can form an electrical connection assembly with one or other number of the flat conductive members 2. The flat conductive member 2 can be a flexible printed circuit board, a flexible flat cable, or other flexible flat electronic components with similar performance.
[0042] refer to Figures 1 to 3The front side of the insulating body 11 has a plurality of receiving grooves 111 that are recessed backwards. The plurality of receiving grooves 111 are arranged in two rows in the left-right direction. Each receiving groove 111 accommodates one conductive terminal 12. Therefore, the plurality of conductive terminals 12 are arranged in two rows in the left-right direction. The rear side of the insulating body 11 has a plug-in groove 112 that is recessed forwards. The plug-in groove 112 is provided for inserting a flat conductive member 2. This embodiment has two layers of the plug-in grooves 112. The upper layer of the plug-in grooves 112 extends left and right and is connected to the corresponding plurality of receiving grooves 111 in the upper layer in a front-to-back manner. The lower layer of the plug-in grooves 112 extends left and right and is connected to the corresponding plurality of receiving grooves 111 in the lower layer in a front-to-back manner.
[0043] like Figure 4 , Figure 5 and Figure 8 As shown, the insulating body 11 also has a locking groove 113 for accommodating the locking piece 13, and the locking groove 113 is formed by being recessed downward from the upper side of the insulating body 11 and connecting the two layers of the plug-in slots 112. The locking piece 13 includes an upper base 131 and a plurality of locking portions 133. The flat conductive piece 2 also has a plurality of through holes 21 aligned with the plurality of locking portions 133 up and down. A portion of the locking portions 133 protrudes downward from the upper base 131, and the plurality of locking portions 133 are inserted into the plurality of through holes 21 one by one to prevent the upper flat conductive piece 2 from withdrawing from the insulating body 11. The locking member 13 further includes a plurality of blocking portions 132 protruding downward from the upper base 131. The plurality of blocking portions 132 and the plurality of conductive terminals 12 are arranged alternately in the left-right direction. The plurality of blocking portions 132 are located in front of the flat conductive member 2. The front-to-back distance between the rear side of the blocking portion 132 and the front side of the locking portion 133 is greater than or equal to the front-to-back distance between the front edge of the through hole 21 and the front edge of the flat conductive member 2, so that the through hole 21 and the locking portion 133 are aligned vertically. The locking member 13 further includes a lower base 134 connecting the plurality of blocking portions 132. A portion of the locking portion 133 protrudes downward from the lower base 134 and is inserted into the through hole 21 of the lower flat conductive member 2, so as to prevent the lower flat conductive member 2 from exiting the insulating body 11.
[0044] Figures 1 to 8 The electrical connector 1 shown uses the first embodiment of the conductive terminal 12 .
[0045] refer to Figure 3 , Figure 6 and Figure 7, each of the conductive terminals 12 is correspondingly received in one of the receiving slots 111 and extends into the plugging slot 112. Specifically, the front portion of the conductive terminal 12 is mainly received in the receiving slot 111, and the rear portion of the conductive terminal 12 passes through the locking slot 113 and extends into the plugging slot 112. The rear portion of the conductive terminal 12 has two first contact arms 121 extending backward into the plugging slot 112, and the rear portion of the conductive terminal 12 also has an elastic connecting portion 122 integrally connecting the two first contact arms 121.
[0046] refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 , two first contact arms 121 are opposite to each other up and down, and abut against the upper and lower sides of the flat conductive member 2. The upper and lower surfaces of each flat conductive member 2 each have a plurality of contact pads 22, which are electrically connected to the plurality of pairs of first contact arms 121 in the same row, and each first contact arm 121 has a contact portion 1211 formed by bending and extending toward the flat conductive member 2, elastically abutting against the contact pad 22 of the flat conductive member 2, and forming an electrical connection with the flat conductive member 2. The first contact portion 1211 also has a flat plate portion 1212 located behind the contact portion 1211. In this embodiment, the edge of the flat plate portion 1212 is connected to the connecting portion 122.
[0047] refer to Figure 3 , Figure 6 and Figure 7 The connecting portion 122 has two connecting arms 1221 extending forward from the same side of the two first contact arms 121 and a bending portion 1222 connecting the front ends of the two connecting arms 1221 .
[0048] refer to Figure 3 , Figure 6 and Figure 7The connecting arm 1221 is connected to one side of the flat plate portion 1212. The connecting arm 1221 includes a bending section a connecting the flat plate portion 1212 and an inclined section b connecting the bending section a and the bending portion 1222. The bending section a is located behind the contact portion 1211, and the bending section a is bent in the vertical direction. The two inclined sections b of the two connecting arms 1221 extend obliquely away from each other from the back to the front, and the width of each inclined section b gradually increases from the back to the front. The position of the bending section a and the inclined section b are set in this way, so that the connecting arm 1221 has sufficient length and width, so that the connecting portion 122 is easy to open and generate elastic force. The minimum distance between the two bending sections a is the minimum distance between the two connecting arms 1221. The minimum distance is greater than the distance between the two contact portions 1211 but less than the thickness of the flat conductive member 2, which is conducive to increasing the contact force of the two first contact arms 121 on the flat conductive member 2 without hindering the insertion of the flat conductive member 2. The bending section a serves as the connection between the connecting arm 1221 and the first contact arm 121 and is located behind the contact portion 1211. The contact portion 1211 is closer to the connection than the bending section 1222. The two bending sections a of the same conductive terminal 12 (i.e., the two connection points between the two connecting arms 1221 and the corresponding first contact arm 121) are bent in opposite directions. In the first embodiment, the two bending sections a located at the upper and lower sides of the flat conductive member 2 are both bent toward the flat conductive member 2.
[0049] refer to Figure 3 , Figure 6 and Figure 7 In the front-to-back direction, the bending portion 1222 is located in front of the contact portion 1211. The bending portion 1222 is arc-shaped, and the diameter of the bending portion 1222 is greater than the minimum distance between the two connecting arms 1221, which is conducive to accumulating elastic force and increasing the contact force of the two first contact arms 121.
[0050] refer to Figure 3 and Figure 6The conductive terminal 12 also has a sleeve portion 123 integrally connected to a pair of the first contact arms 121. The sleeve portion 123 and the two first contact arms 121 are integrally connected by stamping from the same metal plate. The sleeve portion 123 is located in front of the first contact arm 121 and is mainly received in the receiving groove 111. The sleeve portion 123 has four side walls 1231 connected in sequence and a receiving cavity 1232 formed by the four side walls 1231. Each of the receiving cavities 1232 extends along the front-to-back direction for a pair of mating pins to be inserted. The side wall 1231 includes an upper side wall c and a lower side wall e opposite to each other, and a left side wall d and a right side wall (not numbered) opposite to each other. The second contact arm 1233 extends from the front end of the upper side wall c from front to rear, and a pressure arm 1234 extends from the rear end of the upper side wall c from rear to front to above the second contact arm 1233. A pair of first contact arms 121 extend backwards opposite to each other from the rear end of the sleeve portion 123, one of the first contact arms 121 extends backwards from the lower side wall e, and the other first contact arm 121 is laterally connected to the left side wall d, higher than the pressure arm 1234 and extends backwards. The second contact arm 1233 is used to contact the docking pin to form an electrical connection. The pressure arm 1234 is connected to the upper side wall c, and is used to press the second contact arm 1233 downward after the second contact arm 1233 contacts the docking pin, thereby increasing the contact force of the second contact arm 1233 with the docking pin. In this embodiment, the pressure arm 1234 is connected to the upper side wall c and extends from the back to the front, close to the two first contact arms 121 . To avoid stress concentration, the two first contact arms 121 are connected to other different side walls 1231 .
[0051] like Figure 6 and Figure 8 As shown, the sleeve portion 123 has a limiting portion 1235 protruding outward, and the insulating body 11 has an elastic arm 114 extending forward from the rear end of the receiving groove 111, and the elastic arm 114 has a protruding blocking portion 1141, and the blocking portion 1141 is located behind the limiting portion 1235 to prevent the conductive terminal 12 from retreating.
[0052] Figures 9 and 10 1 is a schematic diagram of a second embodiment of the conductive terminal 12. The second embodiment differs from the first embodiment only in the connecting portion 122. In the second embodiment, the upper bending segment a is bent upward, and the lower bending segment a is bent downward, that is, the two bending segments a are bent and extended away from the flat conductive member 2, and the distance between the two bending segments a is greater than the distance between the two contact portions 1211, and also greater than the thickness of the flat conductive member 2. The other two extension segments extend toward the bending portion 1222.
[0053] The present invention does not limit the shape of the bending portion 1222 to be an arc shape. In other embodiments not shown in the figure, the bending portion 1222 can be changed into other bending forms that can generate elastic force, for example, the bending portion 1222 can be changed into a torsion spring shape.
[0054] The electrical connector 1 of the utility model has the following beneficial effects:
[0055] (1) The flat conductive part 2 is inserted between the two first contact arms 121 and contacts the two first contact arms 121 to achieve a detachable electrical connection, and the second contact arm 1233 of the conductive terminal 12 contacts the docking pin, thereby achieving an electrical connection between the flat conductive part 2 and the docking pin. No welding process and riveting process are required, thus avoiding elastic attenuation of the conductive terminal 12 caused by high welding temperature and also eliminating riveting costs.
[0056] (2) The flat conductive member 2 is inserted between the two first contact arms 121 and is crimped with the two first contact arms 121 to achieve a detachable electrical connection. The connecting portion 122 connects the two first contact arms 121. After the flat conductive member 2 is inserted, the two connecting arms 1221 of the connecting portion 122 are stretched apart along with the two first contact arms 121. The bending portion 1222 of the connecting portion 122 generates an elastic force that acts on the two first contact arms 121, thereby increasing the contact force (positive force) of the two first contact arms 121 on the flat conductive member 2, achieving a stable electrical connection, and eliminating the riveting process of connecting the conductive terminal 12 to the flat conductive member 2 (such as FPC, FFC) in the prior art.
[0057] (3) The minimum distance between the two bending segments a, that is, the minimum distance between the two connecting arms 1221 , is greater than the distance between the two contact portions 1211 , so as to reduce the friction resistance of the connecting portion 122 to the flat conductive member 2 .
[0058] (4) The bending portion 1222 is in an arc shape, and the diameter of the bending portion 1222 is greater than the minimum distance between the two connecting arms 1221 . Such a configuration makes it easier to generate elastic force to increase the positive force of the contact portion 1211 .
[0059] (5) The flat conductive member 2 is inserted from back to front between the two first contact arms 121, and during the insertion process, the flat conductive member 2 reaches the contact portion 1211, so that the bent portion 1222 is located in front of the contact portion 1211 in the front-to-back direction, so that the flat conductive member 2 can be fully inserted, so that the through hole 21 can be aligned with the locking portion 133, which facilitates the locking portion 133 to be inserted into the through hole 21, and prevents the flat conductive member 2 from withdrawing from the electrical connector 1.
[0060] (6) The connecting arm 1221 includes a bending section a connecting the first contact arm 121 and an inclined section b connecting the bending section a and the bending portion 1222. The bending section a is located behind the contact portion 1211. The bending section a is bent along the vertical direction. The two inclined sections b of the two connecting arms 1221 extend obliquely away from each other from back to front. The width of each inclined section b gradually increases from back to front. The minimum distance between the two bending sections a is less than the thickness of the flat conductive member 2. In addition, the contact portion 1211 is closer to the bending section a than the bending portion 1222. Such a configuration also makes it easier to generate elastic force to increase the contact force.
[0061] The above detailed description is only an explanation of the preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Therefore, all equivalent technical changes made by using the description and illustrations of the present utility model are included in the patent scope of the present utility model.
