[0096] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in one embodiment of the present invention, these practical details are not necessary. In addition, in order to simplify the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0097] Figure 1 FIG. 1 is a perspective view of a connector device 10 according to an embodiment of the present invention. Figure 2 for Figure 1 Exploded view of the connector device 10. Figure 3 for Figure 2 3D images of the conductive terminal 200 at different viewing angles. Figure 4 for Figure 1 A cross-sectional view of the connector device 10 taken along line segment 4-4. Figure 5 for Figure 1 A cross-sectional view of the connector device 10 taken along line segment 5-5.

[0098] In this embodiment, if Figures 1 to 3 As shown, a connector device 10 includes a base 100 and a conductive terminal 200. The base 100 has a base body 120. The base body 120 includes a top surface 121 and a bottom surface 122 opposite to each other, and the base body 120 has a terminal receiving groove 110, which penetrates the base body 120 along the long axis direction (such as the Z axis) of the base body 120 and connects the top surface 121 and the bottom surface 122 of the base body 120. The terminal receiving groove 110 includes a groove body, a limit groove 130 ( Figure 4 ) and a snap-fit ​​portion 140 ( Figure 5 The slot body (reference terminal receiving slot 110) is the substantial body of the terminal receiving slot 110, and the slot body has a first inner side wall 111 and a second inner side wall 112 opposite to each other ( Figure 5 ), the first inner side wall 111 and the second inner side wall 112 are arranged in sequence along the Y axis, and are both connected to the top surface 121 and the bottom surface 122 of the seat body 120. The engaging portion 140 and the limiting groove 130 are respectively formed in the slot body of the terminal receiving slot 110. For example, the limiting groove 130 is formed on the first inner side wall 111 ( Figure 4 ), and the engaging portion 140 is formed in the limiting groove 130 ( Figure 5 ).

[0099] like Figures 1 to 3 As shown, the conductive terminal 200 is formed by bending an elastic metal sheet and assembled in the slot body of the terminal receiving slot 110 of the base 100. The conductive terminal 200 includes a main body 210, an elastic arm 240 and a pin connecting portion 270 in an integral manner. The main body 210 is a sheet, having an upper surface 211 and a lower surface 212 opposite to each other. The main body 210 includes one or more (such as 2) stop portions 220 and a buckle portion 230. These stop portions 220 are respectively located on two opposite sides of the main body 210 and connected to the upper surface 211 of the main body 210. After the conductive terminal 200 is inserted into the slot body of the terminal receiving slot 110 of the base 100, the limiting slots 130 abut against the stop portions 220 respectively, and the stop portions 220 can limit the body 210 in the limiting slots 130, and the buckle portions 230 and the engaging portions 140 are buckled with each other, so that the body 210 is fixed in the slot body of the terminal receiving slot 110 ( Figure 4 and Figure 5 ). The elastic arm portion 240 includes a reversed connection portion 241, a support portion 242, a bent portion 243 and a conductive portion 244. The reversed connection portion 241 is connected to the lower surface 212 of the main body portion 210, and after extending from the lower surface 212 of the main body portion 210, it is reversed and extends upward. The support portion 242 is located between the reversed connection portion 241 and the bent portion 243, is arranged relative to the main body portion 210, and contacts or lightly presses the second inner side wall 112 of the slot body of the terminal receiving slot 110, that is, the support portion 242 is the extreme protrusion of the elastic arm portion 240 (between the reversed connection portion 241 and the bent portion 243) facing away from the main body portion 210. The bending portion 243 is in a U-shape, a part of which extends obliquely out of the terminal receiving slot 110, and is located between the supporting portion 242 and the conductive portion 244, and is respectively connected to the supporting portion 242 and the conductive portion 244. The conductive portion 244 is located on the free end of the elastic arm portion 240 relative to the main body 210, so that it can contact the contact point (not shown in the figure) of the electronic component later. The pin connecting portion 270 and the reverse folding connecting portion 241 are both connected to the same surface of the main body 210 (such as the lower surface 212), and the pin connecting portion 270 and the reverse folding connecting portion 241 both extend downward from the lower surface 212 of the main body 210 out of the terminal receiving slot 110, so that they can be soldered to the contact point (not shown in the figure) of the circuit board later.

[0100] In this embodiment, specifically, in the elastic arm portion 240, the reverse connection portion 241 gradually extends from the lower surface 212 of the main body portion 210 to the bottom surface 122 of the seat body 120, and is reversed to gradually extend toward the top surface 121 of the seat body 120 and the second inner side wall 112 of the slot body of the terminal receiving slot 110, and after the supporting portion 242 contacts the second inner side wall 112, the bent portion 243 is bent to gradually extend out of the terminal receiving slot 110 (or to the top surface 121 of the seat body 120) toward the top surface 121 and the first inner side wall 111 of the seat body 120. The bent portion 243 extends obliquely from the reverse connection portion 241 toward the direction away from the main body portion 210. The pin connection portion 270 is L-shaped, that is, the pin connection portion 270 further extends a solder ball welding portion 271 away from the main body portion 210. The solder ball welding portion 271 is used to weld solder balls, and is welded to the contact points (not shown) of the circuit board through the solder balls. However, the present invention is not limited thereto.

[0101] like Figure 4 As shown, more specifically, the limiting groove 130 is funnel-shaped, and the limiting groove 130 has a groove bottom surface 131 and two inner walls 132. These inner walls 132 are opposite to each other. The groove bottom surface 131 is located between these inner walls 132 and is adjacent to these inner walls 132. Each inner wall 132 has an inclined surface 133 and a plane 134, and the plane 134 is connected to the inclined surface 133 and is closer to the bottom surface 122 of the seat body 120 than the inclined surface 133.

[0102] In addition, one of the inner walls 132 further has a bottom wall 135, and the plane 134 connects the inclined surface 133 and the bottom wall 135, and the bottom wall 135 is closer to the bottom surface 122 of the base 120 than the plane 134. The inclined surfaces 133 of the inner walls 132 extend downward (e.g., toward the bottom surface 122 of the base 120) and gradually approach each other, thereby gradually shortening the distance between the inclined surfaces 133.

[0103] Therefore, if Figure 4 As shown, when the main body 210 moves downward into the limiting groove 130 , the main body 210 and these stop portions 220 contact the groove bottom surface 131 and these inner walls 132 respectively, so that the inclined surface 133 , the plane 134 and the bottom wall 135 jointly fix the main body 210 in the limiting groove 130 .

[0104] Furthermore, each stop portion 220 has a limiting inclined surface 221 on a side facing away from the main body 210 . The limiting inclined surfaces 221 are arranged opposite to each other and extend downward (such as toward the bottom surface 122 of the seat body 120 ) and gradually approach each other, thereby gradually shortening the distance between the limiting inclined surfaces 221 .

[0105] Therefore, since the spacing G1 of these inclined surfaces 133 is greater than the spacing G2 of these planes 134, when the main body 210 is located in the limiting groove 130, the limiting inclined surfaces 221 of the main body 210 respectively contact the inclined surfaces 133 of the limiting groove 130, and the main body 210 is fixed in the limiting groove 130 and cannot move downward.

[0106] Furthermore, if Figure 5 As shown, the buckle portion 230 and the engaging portion 140 are roughly wedge-shaped. The buckle portion 230 is convexly arranged on the side of the main body 210 facing away from the elastic arm portion 240, and the buckle portion 230 has an upper abutting surface 231 facing upward. The engaging portion 140 is convexly arranged on the groove bottom surface 131 and is located in the middle position of the groove body of the terminal receiving groove 110, and the engaging portion 140 has a lower abutting surface 141 facing downward. Therefore, when the main body 210 moves downward to a certain extent in the limiting groove 130, until the upper abutting surface 231 of the buckle portion 230 and the lower abutting surface 141 of the engaging portion 140 abut against each other, the main body 210 is fixed in the limiting groove 130, so that the main body 210 cannot move upward out of the limiting groove 130.

[0107] like Figure 2 and Figure 5 As shown, in this embodiment, the bending portion 243 has a bending angle θ, so that the connecting portion 244 is offset from the terminal receiving groove 110 in the vertical direction (such as the Z axis), that is, the orthographic projection of the connecting portion 244 is not located in the terminal receiving groove 110. In this embodiment, the bending angle θ is between 90° and 110°, however, the present invention is not limited thereto.

[0108] In addition, since the bending portion 243 has a specific bending angle θ, the elastic arm portion 240 can reduce the force of the supporting portion 242 pressing against the second inner wall 112, thereby preventing the conductive terminal 200 from being inserted into the terminal receiving slot 110 of the base 100 by hard interference.

[0109] In this embodiment, if Figure 2 As shown, the elastic arm portion 240 further includes a narrow opening 250. The narrow opening 250 is a closed contour, formed on the bending portion 243, and extends longitudinally along the long axis trajectory of the elastic arm portion 240, thereby dividing the bending portion 243 into two first arms 255. These first arms 255 are spaced and arranged side by side in the X-axis direction, but the present invention is not limited thereto. The inner surface 251 of the narrow opening 250 has a first section 251A and a second section 251B connected to each other. The first section 251A and the second section 251B intersect with each other. In other words, one end of the narrow opening 250 starts at a position of the bending portion 243 close to the conductive portion 244, forming two bifurcated current paths (i.e., the first arms 255), and the other end of the narrow opening 250 ends and is combined at a position of the bending portion 243 close to the top portion 242.

[0110] Figure 6 FIG. 1 is a perspective view of a connector device 11 according to an embodiment of the present invention. Figure 7 for Figure 6 An exploded view of the connector device 11 is shown. Figure 8 for Figure 6 A cross-sectional view of the connector device 11 taken along line segment 8-8. Fig. 9 for Figure 6 A cross-sectional view of the connector device 11 taken along line segment 9-9. Fig.10 for Figure 6 A cross-sectional view of the connector device 11 taken along line segment 10-10.

[0111] like Figures 6 to 10 As shown, the connector device 11 of this embodiment is substantially the same as the connector device 10 of the above-mentioned embodiment, but the differences are listed as follows. In this embodiment, the upper surface 211 of the main body 210 of the conductive terminal 201 is formed with a recess 232, and the recess 232 has an inner bottom surface 233. Therefore, when the main body 210 is limited in the limiting groove 130, the lower abutting surface 141 of the engaging portion 140 and the buckle portion (such as the inner bottom surface 233 of the recess 232) abut against each other, and the main body 210 is fixed in the limiting groove 130, so that the main body 210 cannot move upward out of the limiting groove 130.

[0112] The narrow opening 250A of the elastic arm portion 240 is simultaneously located on the bending portion 243, the supporting portion 241A and the reverse folded connecting portion 241, and one end of the narrow opening 250A continues to extend to the lower surface 212 of the main body portion 210, so that the first arms 255 defined by the narrow opening 250A are respectively connected to the lower surface 212 of the main body portion 210. The pin connecting portion 270 between the two first arms 255 extends downward from the narrow opening 250A and the terminal receiving slot 110 from the lower surface 212 of the main body portion 210 (i.e., the inner surface 251 of the narrow opening 250A).

[0113] Different from the above-mentioned embodiment in which the supporting portion 242 is a convex point, in this embodiment, the supporting portion 241A is a plane of the first arm 255 facing away from the main body 210. In this embodiment, when the folded connecting portion 241 is folded and tilted upward to reach the second inner side wall 112 of the slot body of the terminal receiving slot 110, the supporting portion 241A (refer to the first arm 255) begins to extend straight along the second inner side wall 112 of the slot body of the terminal receiving slot 110 to the bent portion 243. The bent portion 243 extends out of the terminal receiving slot 110 from the supporting portion 241A in a tilted direction toward the main body 210. In this way, in this embodiment, the supporting portion 241A does not contact or at least contacts the second inner side wall 112 of the slot body of the terminal receiving slot 110, thereby reducing the chance of damage or indentation to the terminal receiving slot 110 of the seat body 120.

[0114] Furthermore, the narrow and long opening 250A includes a first section 252, a second section 253 and a third section 254 connected in sequence. The first section 252 is located on the bending portion 243, the second section 253 is located on the top supporting portion 241A, and the third section 254 is located on the reverse folded connecting portion 241, and the third section 254 is respectively connected to the second section 253 and the lower surface 212 of the main body 210, and the width W1 of the third section 254 is greater than the width W2 of the second section 253. The base 100 further includes a guide frame 150. The guide frame 150 includes a convex rib 151 and a stop plate 152. The convex rib 151 is located in the second section 253, and is connected to the second inner side wall 112 of the slot body of the terminal receiving slot 110 and the stop plate 152, and the width W3 of the stop plate 152 is less than the width W1 of the third section 254. The rib 151 is located between the first arms 255, and the first arms 255 are limited by the guide frame 150 to the second inner side wall 112 of the slot body of the terminal receiving slot 110. For example, the stop plate 152, the rib 151 and the second inner side wall 112 respectively define two receiving areas 153. Therefore, when the conductive terminal 201 is inserted into the terminal receiving slot 110 of the base 100, and the stop plate 152 of the guide frame 150 passes through the third section 254, and the rib 151 moves from the third section 254 into the second section 253, the first arms 255 are respectively limited to the corresponding receiving areas 153, so that the top portion 241A of the reverse folded connection portion 241 is in contact with the second inner side wall 112 of the slot body of the terminal receiving slot 110. In addition, the pin connection portion 270 is approximately Z-shaped instead of L-shaped. The solder ball bonding portion 271 has a recessed portion 272 at its distal end. However, the present invention is not limited thereto.

[0115] Fig.11 FIG. 1 is a perspective view of a connector device 12 according to an embodiment of the present invention. Fig.12 for Fig.11 An exploded view of the connector device 12 is shown. Fig.13 for Fig.12 The conductive terminal 202 is a three-dimensional image at different viewing angles. Figures 11 to 13 As shown, in this embodiment, the connector device 12 is Figure 1The connector device 10 is substantially the same as the connector device 10 of FIG. 1 , however, the differences are listed as follows. The pin connection portion 270 is connected to the inflected connection portion 241. More specifically, the elastic arm portion 240 further includes an arc-shaped opening 260, which is only formed at the lower portion of the inflected connection portion 241 (i.e., the portion below the supporting portion 242), and is not located on the bent portion 243, and the solder ball welding portion 271 of the pin connection portion 270 overlaps with the arc-shaped opening 260 in the vertical direction (such as the Z axis). The pin connection portion 270 extends downward from the inner surface 262 of the arc-shaped opening 260 to the arc-shaped opening 260 and the terminal receiving slot 110. For example, the arc opening 260 separates the folded connection portion 241 into two second arms 261 , and the pin connection portion 270 between the second arms 261 extends downward from the arc opening 260 and the terminal receiving slot 110 from the lower surface 212 of the body 210 (ie, the inner surface 262 of the arc opening 260 ).

[0116] FIG. 14A to FIG. 14C The terminal strip structure 300 of this embodiment can be used in the connector devices 10 to 12 of all the above embodiments, such as Fig.14A As shown, the terminal strip structure 300 includes a strip 310 and a plurality of conductive terminals 202. The strip 310 and the plurality of conductive terminals 202 are integrally formed. The strip 310 includes a plate portion 311 and a plurality of extension portions 312. These extension portions 312 are coplanar with the plate portion 311, and these extension portions 312 are parallel to each other and connected to the same side of the plate portion 311 at intervals. Each extension portion 312 has a neck 313 at the end relative to the plate portion 311, and the neck 313 is connected to the upper surface 211 of the main body portion 210, and the thickness T2 of the neck 313 is less than the thickness T1 of one of the extension portions 312. One end of each extension portion 312 is connected to one side of the plate portion 311, and the other end is connected to the upper surface 211 of the main body portion 210 of one of the conductive terminals 202 through the neck 313.

[0117] like Fig.14A and Fig. 14B As shown, when the assembler inserts the conductive terminals 202 of the terminal strip structure 300 into the plurality of terminal receiving slots 110 disposed on the base 100, the body portion 210 of each conductive terminal 202 is fixed in the terminal receiving slot 110 in the above manner; then, as shown in FIG. Fig.14A and Fig. 14CAs shown, the assembler repeatedly swings the strip 310 (such as swing directions C1 and C2) for a certain number of times based on the X-axis as the rotation axis, and finally breaks the necks 313 from the upper surface 211 of the body 210 due to metal fatigue, thereby completing the step of completely separating the strip 310 from the conductive terminals 202 and moving upward away from the base 100. In this way, the separation process of the conductive terminals 202 can be achieved without using any machine or tool.

[0118] It should be understood that since the elastic arm portion 240 of the conductive terminal 202 has a narrow opening 250, when the assembler repeatedly swings the strip 310, the extension portion 312 of the strip 310 can move into the narrow opening 250, thereby increasing the amplitude of the assembler's repeated swinging of the strip 310 and accelerating the work efficiency.

[0119] Thus, through the above structure, the conductive terminals in the connector device of the present invention can be assembled in the base without hard interference, thereby reducing the chance of uncontrollable warping of the terminals in the base and the overall conductive performance of the connector device.

[0120] Finally, the above disclosed embodiments are not intended to limit the present invention. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all of them can be protected by the present invention. Therefore, the scope of protection of the present invention shall be determined by the definition of the attached claims.
