DETAILED DESCRIPTION

[0023] The utility model will be further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, the connecting terminal of the connector of the utility model includes a connecting part 1 and a mating part 2 connected to the connecting part 1 and plugged with the docking connector. The connecting part 1 and the mating part 2 are both made of conductive materials. The connecting part 1 is used to connect to the insulator of the connector, and the mating part 2 is used to realize electrical signal connection with the docking connector.

[0025] In this embodiment, the connection part 1 includes a first connection side 11 and a second connection side 12 which are L-shaped and perpendicular to each other, the first connection side 11 is perpendicular to a plug-in direction, and the second connection side 12 is parallel to the plug-in direction. A mounting hole 13 is provided through the first connection side 11 along the plug-in direction, and the connection part 1 is installed on the insulator by bolts after passing through the mounting hole 13, and a mounting cavity is provided at a position corresponding to the second connection side 12 on the insulator, and the second connection side 12 extends into the mounting cavity for plugging and mating with the docking terminal of the docking connector. It should be noted that the plug-in direction in the present utility model refers to the height direction of the second connection side 12, the length direction in the present utility model refers to the length direction of the second connection side 12, and the width direction in the present utility model refers to the width or thickness direction of the second connection side 12; and the inward direction along the width direction mentioned in the present utility model refers to the two first mating ends 21 facing each other along the width direction, and the outward direction along the width direction in the present utility model refers to the two first mating ends 21 facing each other along the width direction.

[0026] In this embodiment, the mating portion 2 includes two first mating ends 21 that are relatively arranged, two second mating ends 22 that are relatively attached to the outer side surfaces of the two first mating ends 21, and two supporting ends 23 that are relatively attached to the outer side surfaces of the two second mating ends 22. An insertion cavity 24 is formed between the two first mating ends 21. The two first mating ends 21 are used for plugging and mating with the docking terminals. The two second mating ends 22 are used to increase the contact area with the docking terminals and provide a certain degree of support to the first mating ends 21. The two supporting ends 23 further provide support to the first mating ends 21 and the second mating ends 22, and provide elastic compensation to the first mating end 21 to ensure that the first mating end 21 can press the docking terminal tightly to ensure the normal transmission and conduction of electrical signals.

[0027] In the content defined in this embodiment, the two first mating ends 21 each include a first connecting plate 211 connected to the connecting part 1, a plurality of first elastic arms 212 arranged at intervals along the length direction of the first connecting plate 211, and a plurality of first contact portions 213 arranged on the end of the first elastic arm 212 away from the connecting part 1 along the plug-in direction. The first connecting plate 211 is used to be conductively connected to the second connecting side 12 so as to be electrically connected to the corresponding wire through bolts after the connecting part 1 is connected to the insulator. The first elastic arms 212 are distributed at intervals so as to be respectively used for plugging and mating with the docking terminals, thereby realizing the limiting of the docking terminals. The first contact portions 213 are pressed against the docking terminals through the elastic properties of the first elastic arms 212, thereby realizing conduction between the connecting terminals and the docking terminals after the power is turned on.

[0028] In this embodiment, the first connecting plate 211 is a sheet-like structure and is arranged parallel to the second connecting side 12. The two first connecting plates 211 of the two first mating ends 21 are arranged on opposite sides of the second connecting side 12 along the width direction of the second connecting side 12. Each first connecting plate 211 includes a bonding plate 2a detachably attached to the opposite sides of the second connecting side 12 and a curved plate 2b arranged between the bonding plate 2a and the first elastic arm 212. The bonding plate 2a is arranged parallel to the second connecting side 12 and connected to the second connecting side 12. The bonding plate 2a can be connected to the second connecting side 12 by a fixed connection method, such as welding, or it can be detachably attached to the second connecting side 12, such as by bolt connection, snap connection, etc. For example: a through hole 14 is opened on the bonding plate 2a and the second connecting side 12 along the width direction of the second connecting side 12, and it is fixed by using bolts to facilitate disassembly and installation, so as to facilitate maintenance. The width direction of the curved plate 2b is arranged along the plugging direction, and the length direction of the curved plate 2b is arranged along the length direction of the second connection side 12. The two curved plates 2b of the two first connection plates 211 extend from the side of the bonding plate 2a away from the first connection side 11 to the side away from the second connection side 12 along the plugging direction, and the spacing between the two first connection plates 211 gradually widens and then gradually narrows, so that the middle parts of the two first connection plates 211 are bent outward along the width direction to form a space with narrow ends and wide middle parts. The first elastic arm 212 is connected to the side of the curved plate 2b away from the bonding plate 2a and is enclosed together with the curved plate 2b to form a plugging cavity 24. When the docking terminal contacts the first contact portion 213, the curved plate 2b with an arc-shaped convex structure provides support for the first contact portion 213 and the first elastic arm 212 and facilitates deformation and elastic recovery, so as to facilitate elastic cooperation with the docking terminal.

[0029] In this embodiment, each first elastic arm 212 is formed by extending from the curved plate 2b of the first connecting plate 211 in the plug-in direction toward the side away from the connecting portion 1, and the first elastic arm 212 is connected to one end of the curved plate 2b and smoothly engages with the curved plate 2b and extends in the same direction, so as to facilitate one-piece molding. The first elastic arms 212 each include a first elastic section 2121 extending from the curved plate 2b in the plug-in direction and arranged inwardly in the width direction, a first bent section 2122 bent outwardly in the width direction from the first elastic section 2121, and a second elastic section 2123 arranged outwardly in the width direction from the first bent section 2122. The extension direction of the first elastic section 2121 is consistent with the extension direction of the side of the curved plate 2b away from the bonding plate 2a to form an arc shape. The first elastic section 2121 and the second elastic section 2123 are arranged in an arc shape. 3. The first bending section 2122 and the curved plate 2b are together formed to enclose the insertion cavity 24. The distance between the first bending sections 2122 of the two first mating ends 21 is the narrowest position of the entire insertion cavity 24, and the spacing between the first bending sections 2122 on the two first mating ends 21 is generally smaller than the width of the docking terminal, so that when the docking terminal is inserted into the insertion cavity 24, only the first bending section 2122 contacts it, and the second elastic section 2123 plays a guiding role when the docking terminal is inserted into the insertion cavity 24. When in use, the docking terminal first enters the insertion cavity 24 at the position corresponding to the second elastic section 2123, and then gradually approaches the first bending section 2122 by squeezing the second elastic section 2123. The first bending section 2122 is squeezed to make the first elastic section 2121 deform toward the outer shape, and at the same time, its elastic performance always presses the docking terminal back, until the docking terminal penetrates the position corresponding to the curved plate 2b, and the first bending section 2122 presses against the docking terminal to achieve conduction while limiting the movement of the docking terminal.

[0030] In this embodiment, a plurality of first contact portions 213 are formed one by one at the ends of a plurality of first elastic arms 212 away from the first connecting plate 211, and the inner side surface of the first bending section 2122 is defined as the first contact portion 213. The first contact portions 213 are spaced apart along the length direction relative to the first mating end 21, so that the first contact portions 213 deform with the first elastic arms 212 and squeeze the docking terminals respectively, so as to ensure that when any first elastic arm 212 fails in elasticity and cannot squeeze the docking terminal, the other first elastic arms 212 can still contact the docking terminal and be conductive.

[0031] In the content defined in this embodiment, the two second mating ends 22 each include a second connecting plate 221 connected to the first connecting plate 211, a plurality of second elastic arms 222 spaced apart along the length direction of the second connecting plate 221, and a plurality of second contact portions 223 spaced apart along the plug-in direction on the end of the second elastic arm 222 away from the connecting portion 1, the second connecting plate 221 is used to be conductively connected to the first connecting plate 211 and connected to the second connecting side 12 to achieve conduction between the first connecting plate 211 and the second connecting plate 221, and each second elastic arm 222 is distributed one by one corresponding to the gap between each adjacent two first elastic arms 212 to be respectively used for plugging and mating with the docking terminal, increasing the contact area on the basis of the contact between the first elastic arm 212 and the docking terminal, and each second contact portion 223 presses against the docking terminal through the elastic performance of the second elastic arm 222, so as to achieve conduction between the connecting terminal and the docking terminal after the power is turned on.

[0032] In this embodiment, the second connecting plate 221 is a sheet-like structure and is arranged along the outer side profile of the first connecting plate 211 to also have a bonding plate 2a and a curved plate 2b. The bonding plate 2a of the second connecting plate 221 is arranged parallel to the second connecting side 12 and connected to the bonding plate 2a of the first connecting plate 211. The curved plate 2b of the second connecting plate 221 is bonded and extended along the outer side of the curved plate 2b of the first connecting plate 211, so that the middle parts of the curved plates 2b of the two second connecting plates 221 are bent outward along the width direction to form a space with narrow ends and wide middle parts, and the curved plate 2b of the second connecting plate 221 extends from the side away from the second connecting side 12 to the end of the first elastic section 2121 close to the first bending section 2122, so that the curved plate 2b of the second connecting plate 221 provides support for the first elastic section 2121, reducing the possibility of elastic failure of the first elastic section 2121. Different from the first connecting plate 211, the curved panel 2b of the second connecting plate 221 extends along the outer arm of the first elastic section 2121 away from the side of the bonding plate 2a toward the side close to the first bending section 2122, so that the width of the curved panel 2b of the second connecting plate 221 is greater than the width of the curved panel 2b of the first connecting plate 211, so that the curved panel 2b of the second connecting plate 221 covers most of the first elastic section 2121. After installation, the curved panel 2b of the second connecting plate 221 located outside the first elastic section 2121 increases the clamping force of the first elastic arm 212.

[0033] In this embodiment, in order to be staggered with the first elastic arms 212, each second elastic arm 222 corresponds to the gap between each adjacent first elastic arm 212 in the width direction, and each second elastic arm 222 is formed to extend from the curved plate 2b of the second connecting plate 221 along the plug-in direction and away from the connecting portion 1. Several second elastic arms 222 each include a third elastic segment 2221 extending from the curved plate 2b along the plug-in direction and arranged inwardly inclined along the width direction, a second bent segment 2222 bent inwardly along the width direction from the third elastic segment 2221, a third bent segment 2223 bent outwardly along the width direction from the second bent segment 2222, and a fourth elastic segment 2224 extending from the third bent segment 2223 along a length direction parallel to the second elastic segment 2123 and located between two adjacent first elastic arms 212. Since the second connecting The plate 221 is set, the length of the third elastic section 2221 is much shorter than the length of the first elastic section 2121, the third elastic section 2221 provides support for the second bending section 2222, the third bending section 2223 and the fourth elastic section 2224, and the second bending section 2222 and the third bending section 2223 make the second elastic arm 222 extend to the gap between the two adjacent first elastic arms 212 of the first mating end 21 on the same side, so that the first elastic arm 212 and the second elastic arm 222 are staggered and independent of each other. The distance between the third bending sections 2223 of the two second mating ends 22 is the narrowest position of the entire plug-in cavity 24, and the spacing between the third bending sections 2223 on the two second mating ends 22 is generally smaller than the width of the docking terminal, so that the docking terminal can contact it when it is inserted into the plug-in cavity 24, and the fourth elastic section 2224 plays a guiding role when the docking terminal is inserted into the plug-in cavity 24. When in use, the docking terminal first enters the plug-in cavity 24 at the position corresponding to the fourth elastic section 2224, and then gradually approaches the third bending section 2223 by squeezing the fourth elastic section 2224. The third bending section 2223 is squeezed to cause the second bending section 2222 to deform toward the outer shape. At the same time, its elastic property always presses the docking terminal back until the docking terminal penetrates into the position corresponding to the curved panel 2b. The third bending section 2223 presses against the docking terminal to achieve conduction while limiting the movement of the docking terminal.

[0034] In this embodiment, a plurality of second contact portions 223 are formed one by one at the ends of a plurality of second elastic arms 222 away from the second connecting plate 221, and the inner side surfaces of the third bending section 2223 and the fourth elastic section 2224 are defined as second contact portions 223. The second contact portions 223 are spaced apart along the length direction relative to the second mating end 22, so that the second contact portions 223 are deformed with the second elastic arms 222 and squeeze the docking terminals respectively, so as to ensure that when any first elastic arm 212 fails in elasticity and cannot squeeze the docking terminal, the other first elastic arms 212 can still contact the docking terminal and be conductive.

[0035] In the content defined in this embodiment, the two supporting ends 23 include a third connecting plate 231 connected to the second connecting plate 221, a plurality of elastic support arms 232 arranged at intervals along the length direction of the third connecting plate 231, and a plurality of support portions 233 arranged on the end of the elastic support arm 232 away from the connecting portion 1 along the plug-in direction. The third connecting plate 231 is used to be fitted and connected to the second connecting plate 221 and connected to the second connecting side 12 to achieve the support of the third connecting plate 231 to the second connecting plate 221. The elastic support arms 232 are distributed one by one corresponding to the gaps between each adjacent second elastic arm 222 and extend toward the first elastic arm 212 and support the first elastic arm 212. While the third connecting plate 231 increases the overall strength of the first connecting plate 211, the elastic support arm 232 increases the overall strength of the first elastic arm 212, thereby improving the service life.

[0036] In this embodiment, the third connecting plate 231 is in a sheet-like structure and is arranged along the outer side profile of the second connecting plate 221 to also have a bonding plate 2a and a curved plate 2b. The bonding plate 2a of the third connecting plate 231 is arranged parallel to the second connecting side 12 and connected to the bonding plate 2a of the second connecting plate 221. The curved plate 2b of the third connecting plate 231 is bonded and extended along the outer side of the curved plate 2b of the second connecting plate 221, so that the middle parts of the curved plates 2b of the two third connecting plates 231 are bent outward along the width direction to form a space with narrow ends and wide middle parts, and the side of the curved plate 2b of the third connecting plate 231 away from the second connecting side 12 corresponds to the panel-less arrangement of the first connecting plate 211, so that a part of the curved plate 2b of the second connecting plate 221 is not blocked to reduce the material consumption.

[0037] In this embodiment, in order to be staggered with the second elastic arms 222, each elastic support arm 232 is formed to extend from the curved plate 2b of the third connecting plate 231 along the plug-in direction in the gap between each adjacent second elastic arm 222 in the width direction. The elastic support arms 232 each include a first support segment 2321 extending from the third connecting plate 231 along the length direction of the first elastic arm 212 and attached to the second connecting plate 221, a fourth bent segment 2322 bent inwardly along the width direction from the first support segment 2321, a second support segment 2323 extending obliquely inwardly along the width direction from the fourth bent segment 2322, a fifth bent segment 2324 bent outwardly along the width direction from the second support segment 2323 and pressed against the first elastic segment 2121, and a fifth bent segment 2324 bent outwardly along the width direction from the fifth bent segment 2324. The third support section 2325 extends outward and obliquely toward the second elastic section 2123. The first support section 2321 provides support for the fourth bending section 2322, the second support section 2323, the fifth bending section 2324 and the third support section 2325. The fourth bending section 2322 and the fifth bending section 2324 allow the elastic support arm 232 to extend through the gap between the two adjacent second elastic arms 222 of the second mating end 22 on the same side, so that the second elastic arms 222 and the elastic support arm 232 are staggered and independent of each other. The distance between the fifth bending sections 2324 of the two support ends 23 is the narrowest between the entire two support ends 23 and abuts against the outer side of the first elastic section 2121 to support the first elastic arm 212.

[0038] In this embodiment, a plurality of support portions 233 are formed one by one at an end of a plurality of elastic support arms 232 away from the third connecting plate 231, and the inner side surface of the fifth bending section 2324 is defined as the support portion 233. The support portions 233 are spaced apart along the length direction relative to the third connecting plate 231, so that the support portions 233 can deform with the elastic support arm 232 to support the first elastic arm 212, thereby avoiding the situation where the first elastic arm 212 cannot rebound after being squeezed, and the third support section 2325 can avoid affecting the first elastic arm 212 and stay away from the second elastic section 2123.

[0039] Another embodiment of the connection terminal of the connector of the utility model includes a connection part 1 and a matching part 2 connected to the connection part 1. The structure of the connection part 1 is consistent with the structure of the above-mentioned embodiment and is not repeated here. The matching part 2 includes two first matching ends 21 and two supporting ends 23 arranged opposite to each other. The two first matching ends 21 each include a first connecting plate 211, a plurality of first elastic arms 212 arranged at intervals along the length direction of the first connecting plate 211, a first contact portion 213 formed on the first elastic arm 212, a plurality of second elastic arms 222 arranged at intervals along the length direction of the first connecting plate 211, and a second contact portion 223 formed on the second elastic arm 222. Each second elastic arm 222 is arranged between two corresponding adjacent first elastic arms 212, and the first elastic arm 212 and the second elastic arm 222 are independent of each other. The first elastic arm 212 and the second elastic arm 222 are staggered and distributed at one time and are both connected to the curved plate of the first connecting plate 211. The supporting portion 233 includes a third connecting plate 231 and an elastic supporting arm 232 extending and fitting along the outer side contour of the first connecting plate 211. The third connecting plate 231 is attached to the outer side of the first connecting plate 211 and connected to the second connecting side 12. The elastic supporting arm 232 is arranged in a one-to-one correspondence with each first elastic arm 212 along the width direction to support the first elastic arm 212. The structures of the first connecting plate 211, the first elastic arm 212, the second elastic arm 222, the third connecting plate 231 and the elastic supporting arm 232 are all consistent with the above-mentioned embodiments, and only the angles of each bending are adjusted on this basis so that the first contact portion 213 and the second contact portion 223 can both press the docking terminal and the elastic supporting arm 232 can resist the first elastic supporting arm 232, which will not be repeated here.

[0040] One embodiment of the connecting terminal of the connector of the utility model works as follows: after the connecting part 1 is installed on the insulator of the connector through the first connecting side 11, the first connecting plate 211, the second connecting plate 221 and the third connecting plate 231 are sequentially fitted and connected from the inside to the outside along the width direction, and an insertion cavity 24 is formed between the first connecting plate 211 and the first elastic arm 212 to provide a space for the mating end of the docking terminal to be inserted. During the process of inserting the mating end of the docking terminal into the insertion cavity 24, the second elastic section 2123 guides the docking terminal, and the docking terminal gradually approaches the first contact portion 213 and the second contact portion 223 until the first contact portion 213 and the second contact portion 223 are squeezed, and the first elastic section 2121 is pressed to deform toward the outer shape, and the second connecting plate 221, the third connecting plate 231 and the first supporting section 2321 are all deformed to a certain extent and provide support for the first elastic section 2121, so that the first contact portion 213 rebounds and presses against the docking terminal, thereby achieving conduction between the docking terminal and the connecting terminal.
