The present disclosure relates to a terminal strip structure, a connector device and a conductive terminal of the connector device.
In general, a connector device is a connecting device that is electrically connected to wires, circuit boards and other circuit components. A structure of the connector device includes a base and a plurality of conductive terminals received within the base together.
However, since each of the conductive terminals will be inserted into a terminal receiving slot of the base through hard interferences, the internal stress of the conductive terminal temporarily deformed may cause uncontrollable warping within the terminal receiving slot so as to cause the conductive terminal to be failingly assembled in the high-temperature environment during the surface mount assembly (SMT) process, thereby affecting the overall conductive performance of the connector device.
Therefore, the above-mentioned technologies obviously still have inconveniences and defects, which are issues that the industry needs to solve urgently.
One aspect of the present disclosure is to provide a terminal strip structure, a connector device and a conductive terminal for solving the difficulties mentioned above in the prior art.
In one embodiment of the present disclosure, a conductive terminal is formed by bending an elastic metal sheet and suitable for being installed in a terminal receiving slot of a base, and the conductive terminal includes a main body, an elastic arm portion and a foot connecting portion. The main body includes at least one holding portion and a buckle portion, and the holding portion and the buckle portion are respectively used for fixing the main body within the terminal receiving slot. The elastic arm portion includes a reversed folded portion, an abutment portion, a bending portion and a conductive portion. The reversed folded portion extends downward from a lower surface of the main body and extends upward after being folded. The abutment portion is located between the reversed folded portion and the bending portion, and arranged opposite to the main body. The bending portion is connected to the abutment portion and the conductive portion, respectively. The foot connecting portion is connected to one of the main body and the reversed folded portion, and further provided with a ball soldering member extending outwardly from the foot connecting portion for connecting to soldering balls.
In one embodiment of the present disclosure, a connector device includes a base and a plurality of conductive terminals. The base is formed with a plurality of terminal receiving slots. Each of the terminal receiving slots includes a slot body, an engaging portion and a limiting slot, and the engaging portion and the limiting slot are commonly disposed on one inner surface of the slot body. Each of the conductive terminals includes a main body, an elastic arm portion and a foot connecting portion. The main body is disposed within the slot body and includes at least one holding portion limiting the main body within the limiting slot, and a buckle portion engaged with the engaging portion. The elastic arm portion includes a reversed folded portion, an abutment portion, a bending portion and a conductive portion. The reversed folded portion extends downward from a lower surface of the main body and extends upward after being folded. The abutment portion is located between the reversed folded portion and the bending portion, arranged opposite to the main body, and physically contacted with another inner surface of the slot body. The bending portion protrudes obliquely from the terminal receiving slot, and is connected to the abutment portion and the conductive portion, respectively. The foot connecting portion protrudes downwardly from one of the main body and the reversed folded portion to extend out of the terminal receiving slot. The foot connecting portion is further provided with a ball soldering member extending outwardly from the foot connecting portion for connecting to soldering balls.
In one embodiment of the present disclosure, a terminal strip structure includes a material strip and a plurality of conductive terminals. The material strip includes a plate portion and a plurality of extension portions. The plate portion and the extension portions are coplanar with each other. The extension portions are arranged on a lateral side of the plate portion at intervals. Each of the extension portions protrudes outwards from the plate portion, one end of each of the extension portions facing away from the plate portion is provided with a neck portion, and a thickness of the neck portion is smaller than a thickness of one of the extension portions. Each of the conductive terminals includes a main body, an elastic arm portion and a foot connecting portion. An upper surface of the main body is connected to the neck portion, and the main body includes at least one holding portion and a buckle portion, and the elastic arm portion includes a reversed folded portion, an abutment portion, a bending portion and a conductive portion. The reversed folded portion extends downward from a lower surface of the main body and extends upward after being folded. The abutment portion is located between the reversed folded portion and the bending portion, and arranged opposite to the main body. The bending portion is connected to the abutment portion and the conductive portion, respectively. The foot connecting portion is connected to one of the main body and the reversed folded portion, and the foot connecting portion is further provided with a ball soldering member extending outwardly. After the conductive terminals of the terminal strip structure respectively are inserted into a plurality of terminal receiving slots of a base, the material strip is completely separated from the conductive terminals by repeatedly swinging the material strip frontwards and backwards to break the neck portions.
Thus, through the construction of the embodiments above, the conductive terminal of the disclosure can be assembled into the terminal receiving slot of the base without hard interference, thereby reducing the possibility of the conductive terminal being uncontrollable warped in the base so as to lower the overall conductive performance of the connector device.
The above description is merely used for illustrating the problems to be resolved, the technical methods for resolving the problems and their efficacies, etc. The specific details of the present disclosure will be explained in the embodiments below and related drawings.
The disclosure can be more fully understood by reading the following detailed description of the embodiment, with reference made to the accompanying drawings as follows:
Reference will now be made in detail to the present embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. According to the embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the present disclosure.
Reference is now made to
As shown in
In the embodiment, specifically, the reversed folded portion 241 is gradually extended downward to the bottom surface 122 of the base body 120 from the lower surface 212 of the main body 210, and redirected to extend gradually upward to the top surface 121 of the base body 120 and the second inner surfaces 112 of the slot body of the terminal receiving slot 110 after being folded.
After the abutment portion 242 is contacted with the second inner surfaces 112, a part of the bending portion 243 gradually extends toward the top surface 121 of the base body 120 and the first inner surface 111 of the slot body of the terminal receiving slot 110 (
As shown in
In addition, one of the inner walls 132 is further provided with a bottom wall 135. The flat surface 134 is connected to the inclined surface 133 and the bottom wall 135, and the bottom wall 135 is closer to the bottom surface 122 of the base body 120 than the flat surface 134. The inclined surfaces 133 of these inner walls 132 are respectively extended downward (e.g., toward the bottom surface 122 of the base body 120) and are gradually approached to each other, thereby gradually shortening the distance between the inclined surfaces 133.
Therefore, as shown in
Furthermore, one side of each of the holding portions 220 facing away from the main body 210 is provided with a limiting slope 221, the limiting slopes 221 are arranged opposite to each other, and respectively extended downward (e.g., extended towards the bottom surface 122 of the base body 120) to gradually approach each other, thereby gradually shortening the distance between the limiting slopes 221.
Therefore, since a distance G1 between these inclined surfaces 133 is greater than a distance G2 between these flat surfaces 134, when the main body 210 is located within the limiting slot 130, the limiting slopes 221 of the main body 210 respectively contact the inclined surfaces 133 of the limiting slot 130 so that the main body 210 can be held within the limiting slot 130 for preventing from moving downward.
Furthermore, as shown in
As shown in
In addition, since the bending portion 243 has a specific bending angle θ, the elastic arm portion 240 can reduce the force of the abutment portion 242 pressing against the second inner surface 112, thereby preventing the conductive terminal 200 from being inserted into the terminal receiving slot 110 of the base 100 through hard interference.
In this embodiment, as shown in
As shown in
The elongated hole 250A of the elastic arm portion 240 is collectively located on the bending portion 243, the abutment portion 241A and the reversed folded portion 241, and the elongated hole 250A continuously extends to the lower surface 212 of the main body 210, so that the first support arms 255 defined by the elongated hole 250A are respectively connected to the lower surface 212 of the main body 210. The foot connecting portion 270 located between the first support arms 255 extends downwardly from the lower surface 212 of the main body 210 (i.e., the inner surface 251 of the elongated hole 250A) to extend out of the elongated hole 250A and the terminal receiving slot 110.
Different from the abutment portion 242 of the above embodiment which is the outermost protruding point, in this embodiment, the abutment portion 241A is a flat plane of the first support arms 255 facing away from the main body 210. In this embodiment, the reversed folded portion 241 which is folded is extended obliquely to reach upward the second inner surfaces 112 of the slot body of the terminal receiving slot 110, the abutment portion 241A (refer to the first support arm 255) begins to extend linearly to the bending portion 243 along the second inner surfaces 112 of the slot body of the terminal receiving slot 110. The bending portion 243 obliquely extends out of the terminal receiving slot 110 according to a direction from the abutment portion 241A toward the main body 210. Thus, in the embedment, the abutment portion 241A does not contact or at least surface contact with the second inner surface 112 of the slot body of the terminal receiving slot 110, so as to lower the possibilities of damage or indentation to the terminal receiving slot 110 of the base body 120.
In addition, the elongated hole 250A includes a first section 252, a second section 253 and a third section 254 which are connected in sequence. The first section 252 is disposed on the bending portion 243, the second section 253 is disposed on the abutment portion 241A, and the third section 254 is disposed on the reversed folded portion 241, and the third section 254 is connected to the second section 253 and the lower surface 212 of the main body 210. A width W1 of the third section 254 is greater than a width W2 of the second section 253. The base 100 further includes a guide frame 150. The guide frame 150 includes a protruding rib 151 and a stopping plate 152. The protruding rib 151 is located within the second section 253 and connected to the second inner surface 112 of the slot body of the terminal receiving slot 110 and the stopping plate 152, and a width W3 of the stopping plate 152 is smaller than a width W1 of the third section 254. The protruding rib 151 is located between the first support arms 255, and the first support arms 255 are position-limited to the second inner surface 112 of the slot body of the terminal receiving slot 110 by the guide frame 150. For example, two accommodation areas 153 are respectively defined by the stopping plate 152, the protruding rib 151 and the second inner surface 112 of the slot body. Therefore, when the conductive terminal 201 is inserted into the terminal receiving slot 110 of the base 100, and the stopping plate 152 of the guide frame 150 passes through the third section 254, and the protruding rib 151 moves into the second section 253 from the third section 254, so that these first support arms 255 are respectively position limited to the corresponding accommodation areas 153. Therefore, it is helpful to realize that the abutment portion 241A of the reversed folded portion 241 is in surface contact with the second inner surface 112 of the slot body of the terminal receiving slot 110. In addition, the foot connecting portion 270 is approximately Z-shaped rather than L-shaped. The distal end of the ball soldering member 271 is formed with a recessed portion 272. However, the present disclosure is not limited thereto.
As shown in
It is noted, since the elastic arm portion 240 of the conductive terminals 202 is formed with an elongated hole 250, when the assembler repeatedly swings the material strip 310, the extension portions 312 of the material strip 310 can move into the elongated hole 250, thereby increasing the amplitude of repeated swings by the assembler so as to speed up the operation time.
Thus, through the construction of the embodiments above, the conductive terminal of the disclosure can be assembled into the terminal receiving slot of the base without hard interference, thereby reducing the possibility of the conductive terminal being uncontrollable warped in the base so as to lower the overall conductive performance of the connector device.
Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the present disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
