Detailed ways

The connecting terminal and terminal assembly of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present utility model, and are not intended to limit it in any way. Throughout the drawings, the same reference numerals designate the same or similar parts.

Referring to FIGS. 1-6 , the connecting terminal according to the present invention includes a first connecting portion 16 and a second connecting portion 12 . The first connection part 16 is used for connecting with the power distribution connector, and the second connection part 12 is used for connecting with electrical devices (such as power supply, circuit board, etc.) or wires. The mating connector has a mating end 20 for mating connection with the first connecting portion 16 of the connecting terminal. The insertion direction of the first connection portion 16 of the connection terminal and the mating end 20 of the power distribution connector is shown by arrow A in FIG. 1 . In the embodiment shown in the drawings, the first connecting part 16 has a body 10 and corrugations 11 ; in other embodiments, the corrugated section 11 can also occupy the entire area of the first connecting part 16 .

In a specific embodiment, the mating end 20 of the power distribution connector has a bottom wall 22 and a pair of curved arms 23 extending upward from the two side edges of the bottom wall 22, and the bottom wall 22 and the pair of curved arms 23 enclose a Receive slot 21. The receiving slot 21 is used to receive the first connecting portion 16 , wherein the end 25 of the curved arm 23 is used to fasten the first connecting portion 16 . The size of the power distribution connector is usually a standard specified value, for example, the vertical distance between the end 25 of the curved arm 23 and the bottom wall 22 is a standard specified value, so that the first connecting part 16 of the connecting terminal that is plugged with it should be Have the corresponding standard specified thickness. However, under the premise of satisfying the electrical performance, the thickness reduction of the connecting terminal can save the material cost. However, when connecting the connecting terminal with a thickness thinner than the original standard and connecting with the original standard power distribution connector, there is a problem of clamping discomfort. matching problem. In order to solve this problem, the inventor of the present invention effectively increases the space thickness of the first connecting portion 16 by providing corrugations 11 on the first connecting portion 16 of the connecting terminal. Referring to Fig. 2, the thickness _H2 of the space formed after the corrugation 11 is set is significantly greater than the thickness H1 of the body 10 of the first connecting part 16, and the thickness _{H2 of} the space can meet the connection requirements of the original standard for power distribution connectors .

In the present invention, the corrugation extension direction of the corrugation 11 (ie, the propagation direction of the wave) is not perpendicular to the insertion direction A of the first connecting portion 16 into the receiving groove 21 . In a preferred embodiment, the corrugation extension direction of the corrugation 11 is consistent with the insertion direction A of the first connecting portion 16 into the receiving groove 21 , that is, substantially along the same direction. In a more preferred embodiment, the corrugation extension direction of the corrugation 11 is parallel to the insertion direction A of the first connecting portion 16 into the receiving groove 21 . The above arrangement makes the clamping position fixed when the connecting terminal is connected to the power distribution connector, the operation is convenient, and the electrical connection is stable. The corrugation 11 can be manufactured by a simple embossing process, and multiple connection terminals with the corrugation 11 can be stacked closely together, which is convenient for saving space during storage and transportation. However, if the corrugated extension direction of the corrugated 11 is set to be perpendicular to the insertion direction A of the first connecting portion 16 inserted into the receiving groove 21, it cannot be guaranteed that the ends 25 of the pair of curved arms 23 of the power distribution connector will be connected each time they are connected. All are clipped with the top of corrugated 11.

The corrugation 11 includes crests 14, and the crests 14 extend continuously to the edge of the first connecting part 16 perpendicular to the insertion direction A (width direction) of the first connecting part 16, so that when the connecting terminal is docked with the receiving groove 21 of the power distribution connector, The tip 25 of the curved arm 23 of the receiving groove 21 can always remain in contact with the crest 14 .

In some embodiments, the corrugations 11 are continuous, and each corrugation 11 has a crest 14 and a trough 15 , and the crest 14 and the trough 15 respectively protrude from the surface of the body 10 . In a preferred embodiment, the multiple corrugations 11 are sinusoidal, so that the vertices of each crest 14 are located on the same straight line, and the vertices of each wave trough 15 are also located on the same straight line, so that when the connecting terminal is connected to the power distribution connector The crests 14 of the corrugations 11 are in contact with the ends 25 of the pair of curved arms 23 at multiple points, and the troughs 15 of the corrugations 11 are in contact with the bottom wall 22 at multiple points. This connection method can improve the effectiveness and stability of the electrical connection. In some embodiments, the thickness H ₂ of the space formed by the corrugations 11 (ie the vertical distance between the crests 14 and the troughs 15 ) is an integer multiple of the thickness H ₁ of the body 10 of the first connecting portion 16 . In a specific embodiment, the thickness _H2 of the space formed by the corrugations ₁₁ is twice the thickness H1 of the body 10 of the first connecting portion 16, thereby saving 50% of the material cost.

The insertion direction A of the second connecting portion 12 and the first connecting portion 16 used to connect the connecting terminal to an electrical device or wire can be arranged in parallel or at a certain angle (for example, perpendicular). In the embodiment shown in FIG. 1, the second connecting portion 12 has plug pins for plugging with electrical devices, such as plugging with a printed circuit board (PCB), wherein the extending direction of the plug pins is the same as that of the first connecting portion. The extending directions of the corrugations of 16 are parallel. In another embodiment, the second connecting portion 12 has a crimping arm for crimping the wire.
