[0033] Reference is made below to Figures 1 - 5 Describe the connector 100 according to an embodiment of the present utility model. The clamping member 21 of the connector 100 forms the female terminal of the connector 100. The clamping member 21 is inserted into the insertion slot 221. When the male connector end 1 is connected to the female connector end 2, the insertion protrusion 12 is inserted into the clamping gap between the first elastic piece 211 and the second elastic piece 212 of the clamping member 21, and both sides of the insertion protrusion 12 are respectively clamped with the first elastic piece 211 and the second elastic piece 212 to form at least two groups of alignment contact points, thereby improving the contact effect between the insertion protrusion 12 of the male connector end 1 and the female terminal formed by the clamping member 21 of the female connector end 2 and ensuring stable current transmission. At the same time, the one-to-one correspondence and cooperation between the plurality of insertion protrusions 12 and the plurality of clamping members 21 form multiple groups of current transmission paths, which can meet the large-current usage scenarios.

[0034] As Figures 1 - 5 shown, a connector 100 according to an embodiment of the present utility model includes: a male connector end 1, a female connector end 2, and a clamping member 21.

[0035] Among them, the male connector end 1 is provided with an insertion protrusion 12; the female connector end 2 is formed with an insertion slot 221, and the insertion protrusion 12 is adapted to be correspondingly inserted into the insertion slot 221; the clamping member 21 is provided in the insertion slot 221, and the clamping member 21 is provided with a first elastic piece 211 and a second elastic piece 212 distributed oppositely, and a clamping gap for passing through the insertion protrusion 12 is formed between the first elastic piece 211 and the second elastic piece 212. The first elastic piece 211 includes at least two spaced-apart first pressing portions 2111, the second elastic piece 212 includes at least two spaced-apart second pressing portions 2121, and the at least two first pressing portions 2111 and the at least two second pressing portions 2121 are distributed in one-to-one correspondence to form at least two groups of alignment contact points on both sides of the insertion protrusion 12.

[0036] In practice, the insertion protrusion 12 can be an insertion pin. The insertion protrusion 12 is correspondingly inserted into the insertion groove 221, and a clamping member 21 is provided in the insertion groove 221. The overall material of the clamping member 21 is a metal conductive material, and the insertion protrusion 12 of the male connector end 1 is also made of a metal conductive material. When the insertion protrusion 12 is in pressing contact with the first elastic piece 211 and the second elastic piece 212 of the clamping member 21, an electrical connection between the insertion protrusion 12 and the clamping member 21 is formed. That is, the insertion protrusion 12 is the insertion terminal of the male connector end 1, and the clamping member 21 is the female terminal of the female connector end 2.

[0037] Moreover, the first elastic piece 211 of the clamping member 21 is provided with a plurality of first pressing portions 2111, and the second elastic piece 212 is provided with a plurality of second pressing portions 2121. The plurality of first pressing portions 2111 and the plurality of second pressing portions 2121 correspond to each other one by one, and a clamping gap is left between the first elastic piece 211 and the second elastic piece 212. When the insertion protrusion 12 is inserted into the clamping gap between the first elastic piece 211 and the second elastic piece 212, one side of the insertion protrusion 12 contacts the plurality of first pressing portions 2111, and the other side contacts the plurality of second pressing portions 2121.

[0038] That is to say, at least two groups of alignment contact points are provided on both sides of the insertion protrusion 12. For example, when both the first pressing portion 2111 and the second pressing portion 2121 are two, two groups of alignment contact points are set. And by the way of clamping with the first elastic piece 211 and the second elastic piece 212, the contact reliability between the insertion protrusion 12 and the clamping member 21 can be improved, thereby preventing the problem that the insertion protrusion 12 and the clamping member 21 are not in place in contact and ensuring stable current transmission.

[0039] Of course, when the areas of the insertion protrusion 12 facing the first elastic piece 211 and the second elastic piece 212 are relatively large, the first elastic piece 211 can be provided with a plurality of pieces, and the second elastic piece 212 can also be provided with a plurality of pieces. The plurality of first elastic pieces 211 and the plurality of second elastic pieces 212 are distributed opposite to each other one by one, thereby increasing the number of the first pressing portions 2111 and the second pressing portions 2121, and thus increasing the pressing area between the insertion protrusion 12 and the first elastic piece 211 and the second elastic piece 212 to ensure reliable electrical connection between the insertion protrusion 12 and the first elastic piece 211 and the second elastic piece 212.

[0040] In some embodiments, the clamping member 21 further includes a connecting portion 213. The connecting portion 213 is installed in the insertion groove 221 and is adapted to pass through the insertion groove 221; both the first elastic piece 211 and the second elastic piece 212 are connected to the connecting portion 213 and extend toward the side away from the connecting portion 213 and then bend toward the side close to the connecting portion 213 to form a bending structure, and the first pressing portion 2111 and the second pressing portion 2121 are respectively arranged on the corresponding bending structures.

[0041] Combined Figure 1 andFigure 2 As shown, the connecting portion 213 can be integrally formed with the first elastic piece 211 and the second elastic piece 212. The structures of the first elastic piece 211 and the second elastic piece 212 are the same, and both are configured such that one end is connected to the connecting portion 213, and the other end extends away from the connecting portion 213 and then bends toward the side close to the connecting portion 213 to form a bending structure. That is, when the inserting convex portion 12 is inserted between the first elastic piece 211 and the second elastic piece 212, it actually presses against the two bending structures. By setting the first elastic piece 211 and the second elastic piece 212 to have a bending structure, it is convenient for the inserting convex portion 12 to press against the first elastic piece 211 and the second elastic piece 212. And when pressing, it provides a space for the first elastic piece 211 and the second elastic piece 212 to be elastically deformed, and at the same time, it is also convenient for the first elastic piece 211 and the second elastic piece 212 to be connected to the connecting portion 213.

[0042] In some embodiments, the bending structure is provided with slot holes 2113 between two adjacent first pressing portions 2111 and / or between two adjacent second pressing portions 2121.

[0043] First, in combination with Figure 1 and Figure 2 As shown, when slot holes 2113 are provided in both the first elastic piece 211 and the second elastic piece 212, or when slot holes 2113 are provided in the first elastic piece 211 or the second elastic piece 212, when the first pressing portion 2111 and the second pressing portion 2121 respectively come into contact and press against the inserting convex portion 12, it can prevent the first elastic piece 211 from being too hard. The setting of the slot holes 2113 facilitates the inserting convex portion 12 to come into contact and press against the first elastic piece 211 and the second elastic piece 212, enabling the first elastic piece 211 and / or the second elastic piece 212 to have a certain deformation space, so that it is convenient for the inserting convex portion 12 to always maintain a pressing contact with the first elastic piece 211 and the second elastic piece 212. And since the slot holes 2113 are located between two adjacent first pressing portions 2111, it can ensure that when the inserting convex portion 12 presses against multiple first pressing portions 2111, the force is balanced. At the same time, when the inserting convex portion 12 presses against multiple second pressing portions 2121, it can ensure that the force is balanced when the inserting convex portion 12 presses against the multiple second pressing portions 2121.

[0044] In some embodiments, the bending structure has an outer side surface 2122 and an inner side surface 2123 connected to each other. The inner side surface 2123 is close to the middle position of the connecting portion 213, and the outer side surface 2122 is close to the end position of the connecting portion 213. The slot holes 2113 extend along the inner side surface 2123 of the bending structure to the outer side surface 2122.

[0045] Specifically, the outer side surface 2122 of the bending structure is connected to the connecting portion 213. The inner side surface 2123 of the bending structure is bent and connected to the outer side surface 2122, and the inner side surface 2123 is bent inward relative to the outer side surface 2122. Here, the side close to the central positions of the first elastic piece 211 and the second elastic piece 212 is the inner side, and the side far from the central positions of the first elastic piece 211 and the second elastic piece 212 is the outer side. By extending the slot hole 2113 along the inner side surface 2123 of the bending structure towards the outer side surface 2122, when the plugging convex portion 12 is in pressing contact with the inner side surface 2123, firstly, due to the space between the inner side surface 2123 and the outer side surface 2122, it can be ensured that the plugging convex portion 12 is in contact with the inner side surface 2123 and the bending structure has a certain deformation space. When the distance between the first elastic piece 211 and the second elastic piece 212 is less than the thickness of the plugging convex portion 12 in the distribution direction of the first elastic piece 211 and the second elastic piece 212, it can be ensured that the plugging convex portion 12 can be smoothly plugged into the clamping gap formed between the first elastic piece 211 and the second elastic piece 212 and is pressed against the first elastic piece 211 and the second elastic piece 212.

[0046] In addition, the slot hole 2113 extends along the inner side surface 2123 of the bending structure to the outer side surface 2122, which is equivalent to that the two adjacent first pressing portions 2111 can respectively press against the plugging convex portion 12. At the same time, when the two adjacent first pressing portions 2111 are pressed, their deformation degrees may not be the same. Then, when the plugging convex portion 12 is slightly inclined, it can still be ensured that the plugging convex portion 12 is pressed against the two adjacent first pressing portions 2111.

[0047] In some embodiments, the female end 2 of the connector includes a female end sheath 22. A plugging slot 221 is arranged inside the female end sheath 22. One of the clamping member 21 and the female end sheath 22 is provided with a first clamping portion 2132 and the other is provided with a clamping interface 224. When the clamping member 21 is installed in the plugging slot 221, the first clamping portion 2132 is clamped at the clamping interface 224.

[0048] Firstly, the connecting portion 213 is provided with the first clamping portion 2132, and the female end sheath 22 is provided with the plugging slot 221. That is to say, the female end sheath 22 is provided with the clamping interface 224 at the plugging slot 221. The clamping interface 224 is communicated with the plugging slot 221, and the first clamping portion 2132 is clamped at the clamping interface 224; or the first clamping portion 2132 is arranged on the side wall of the female end sheath 22 and the clamping interface 224 is arranged on one side of the connecting portion 213, which can also realize the clamping of the connecting portion 213 and the female end sheath 22.

[0049] The female end sheath 22 of the utility model embodiment is provided with a card interface 224, and a first card connection portion 2132 is provided on the connecting portion 213, the clamping member 21 is connected to the plug-in slot 221, and a through hole 226 is provided at the bottom of the plug-in slot 221, one end of the clamping member 21 is passed through the through hole 226 and connected to the plug-in slot 221, and is carded with the card interface 224 provided on the side wall of the plug-in slot 221 through the first card connection portion 2132 of the connecting portion 213, thereby ensuring the stability of the clamping member 21 connected to the plug-in slot 221.

[0050] Of course, in actual design, a first clamping portion 2132 can be provided on different sides of the connecting portion 213. At the same time, a plurality of clamping interfaces 224 are provided at the position of the plug-in slot 221 corresponding to the connecting portion 213, and the plurality of first clamping portions 2132 correspond to the plurality of clamping interfaces 224 one-to-one, thereby further improving the stability and reliability of the connection of the clamping member 21 in the plug-in slot 221.

[0051] In some embodiments, the clamping member 21 includes a connecting portion 213, which is installed in the plug-in slot 221 and is suitable for passing through the plug-in slot 221. The first spring piece 211 and the second spring piece 212 are both connected to the connecting portion 213. The first clamping portion 2132 is constructed as a clamping bent plate. The connecting portion 213 includes a main body portion 2131 and a clamping bent plate. The main body portion 2131 connects the relatively distributed first spring piece 211 and the second spring piece 212, and one end of the clamping bent plate is connected to one side of the main body portion 2131 and the other end is bent and extended toward the outside. When the clamping member 21 is installed in the plug-in slot 221, the clamping bent plate is suitable for being clamped at the card interface 224.

[0052] Reference Figure 2 As shown, one end of the snap-fit bent plate is connected to the main body 2131, and the other end is inclined and bent toward the outside of the main body 2131, and the side wall of the female end sheath 22 is provided with a snap interface 224. First, the clamping member 21 is installed in the plug-in slot 221, and the clamping member 21 forms the female end terminal of the connector female end 2, thereby connecting the connector male end 1 with the connector female end 2 to achieve the connection between the two; when the clamping member 21 is located in the plug-in slot 221, the snap-fit interface 224 of the side wall of the female end sheath 22 forms a lap sill, and the snap-fit bent plate overlaps the lap sill, so that the clamping member 21 cannot continue to move toward the side away from the connector male end 1, so as to ensure the reliability of the connection between the clamping member 21 and the plug-in slot 221, thereby ensuring that the plug-in protrusion 12 of the connector male end 1 and the clamping member 21 are better matched and contacted, thereby improving the reliability of current transmission.

[0053] In some embodiments, the connecting portion 213 is installed in the plug-in slot 221 and is suitable for connecting to the first control board 3 after passing through the plug-in slot 221. A sheath baffle 225 is provided on the side of the female end sheath 22 facing away from the male end 1 of the connector, and the sheath baffle 225 is used to plug and cooperate with the first control board 3.

[0054] In practice, the female end sheath 22 is made of insulating material to protect the clamping member 21, that is, to protect the female end terminal, and at the same time improve the safety of the electrical connection between the clamping member 21 and the insertion convex portion 12; referring to Figure 3 As shown, the sheath baffles 225 can be set to multiple or one. When the sheath baffles 225 are set to multiple, the first control board 3 is provided with multiple insertion holes, and the multiple sheath baffles 225 are inserted into the multiple insertion holes of the first control board 3 to be connected to the first control board 3, realizing the connection between the female end sheath 22 and the first control board 3. That is, by setting the sheath baffles 225, it is convenient to connect the female end sheath 22 and the first control board 3; at the same time, the connecting portion 213 of the clamping member 21 is provided with a connecting pin 2133, and the connecting pin 2133 passes through the through hole 226 of the female end sheath 22 and is welded to the first control board 3 to form an electrical connection with the first control board 3. That is, the connection between the connecting portion 213 of the clamping member 21 and the first control board 3, and the connection between the sheath baffle 225 and the first control board 3 improve the reliability of the connection between the female end 2 of the connector and the first control board 3.

[0055] In addition, the bottom of the female end sheath 22 is also provided with a second positioning post 227 and a sheath support seat 228. The second positioning post 227 is used for positioning and enabling the female end 2 of the connector to be accurately inserted into the first control board 3, and the multiple sheath support seats 228 enable the female end 2 of the connector to stand stably on the first control board 3.

[0056] In some embodiments, one side of the insertion convex portion 12 facing the female end 2 of the connector is provided with an inclined first chamfer 122, and one side of the insertion slot 221 facing the male end 1 of the connector has a second chamfer 222. When the insertion convex portion 12 is inserted into the insertion slot 221, the first chamfer 122 can enter the insertion slot 221 along the second chamfer 222 for guiding.

[0057] Among them, one end of the insertion convex portion 12 facing the female end 2 of the connector is provided with a first chamfer 122. Similarly, one side of the insertion slot 221 facing the male end 1 of the connector is provided with an open mouth, and the edge of the open mouth is provided with a second chamfer 222. And the second chamfer 222 corresponds to the position of the first chamfer 122, and the setting of the second chamfer 222 is equivalent to expanding the open mouth of the insertion slot 221 facing the male end 1 of the connector, so as to facilitate the first chamfer 122 of the insertion convex portion 12 to be inserted into the insertion slot 221 along the position of the second chamfer 222. That is, the settings of the first chamfer 122 and the second chamfer 222 can guide the insertion convex portion 12 to be inserted into the insertion slot 221 and connected to the clamping member 21, avoiding the deviation of the male end 1 and the female end 2 of the connector during the mating insertion, and preventing the problem of metal chips generated due to a large deviation during the mating insertion.

[0058] Furthermore, in combination with Figure 1As shown, a first chamfer 122 can be set on multiple surfaces of the end of the plug-in protrusion 12 facing the plug-in groove 221, and a plurality of second chamfers 222 are set on the edge around the open mouth of the plug-in groove 221, and the plurality of first chamfers 122 correspond one-to-one to the plurality of second chamfers 222, thereby further improving the guiding function of the plug-in protrusion 12 when installed in the plug-in groove 221, and preventing a large offset between the plug-in protrusion 12 and the clamping member 21 when they are connected.

[0059] In some embodiments, the plug-in slot 221 also includes a guide protrusion 223, which extends along the depth direction of the plug-in slot 221. When the plug-in protrusion 12 is plugged into the plug-in slot 221, a portion of the side wall of the plug-in protrusion 12 contacts the guide protrusion 223 and is guided and corrected by the guide protrusion 223.

[0060] In practice, by providing a guide protrusion 223 in the plug-in groove 221, when the plug-in protrusion 12 is plugged in along the open mouth of the plug-in groove 221, a part of the side surface of the plug-in protrusion 12 contacts the guide protrusion 223, that is, the guide protrusion 223 limits the plug-in path of the plug-in protrusion 12, thereby ensuring that the plug-in protrusion 12 is accurately plugged in between the first spring piece 211 and the second spring piece 212 of the clamping part.

[0061] Figure 1 When the first elastic sheet 211 and the second elastic sheet 212 are opposite to each other along the first direction, the guide protrusion 223 is arranged on a side wall of the plug slot 221 in the second direction, the first direction intersects with the second direction, and the first direction is Figure 1 The left and right directions are the left and right directions, and the second direction is the direction in which the multiple first clamping parts 2111 or the multiple second clamping parts 2121 are spaced apart. The guide protrusion 223 can be arranged on a side wall of the plug-in slot 221 along the second direction. When the plug-in protrusion 12 is plugged into the plug-in slot 221, a side surface of the plug-in protrusion 12 along the second direction contacts the guide protrusion 223 of the plug-in slot 221 and enters between the first elastic piece 211 and the second elastic piece 212 of the clamping member 21 along the guide protrusion 223, thereby ensuring the accuracy and stability of the plug-in. At the same time, the guide protrusion 223 can also achieve the function of guiding and correcting when the plug-in protrusion 12 deviates along the second direction between the first elastic piece 211 and the second elastic piece 212.

[0062] In some embodiments, the connector 100 further includes a male end sheath 11 , and the plug-in protrusion 12 is connected to the male end sheath 11 and extends out of the male end sheath 11 at one end facing away from the female end 2 of the connector for connecting to the second control board 4 .

[0063] In practice, the male-end sheath 11 is made of insulating material. While connecting to the plug-in protrusion 12, it can also insulate the plug-in protrusion 12 from the outside. The plug-in protrusion 12 extends out of the male-end sheath 11 to connect to the second control board 4, enabling electrical connection between the second control board 4 and the plug-in protrusion 12, while insulating the plug-in protrusion 12 from the outside. That is, after the female end 2 of the connector is connected to the male end 1 of the connector, and the plug-in protrusion 12 of the female end 2 of the connector is connected to the first control board 3, and the clamping member 21 of the male end 1 of the connector is connected to the second control board 4, the connection between the first control board 3 and the second control board 4 is achieved.

[0064] In addition, a support post 111 is provided on the side of the male-end sheath 11 facing away from the female-end sheath 22. The plug-in protrusion 12 passes through the male-end sheath 11 and is fixedly connected to the second control board 4. The support post 111 is provided on the side of the male-end sheath 11 facing away from the female-end sheath 22, and the second control board 4 is attached to the support post 111, realizing the support of the second control board 4 by the support post 111, thereby preventing the second control board 4 from tilting under the action of external force. In addition, a first positioning post 115 is also provided on the side of the male-end sheath 11 facing away from the female-end sheath 22. The first positioning post 115 is inserted into the second control board 4 for positioning when the male-end sheath 11 and the second control board 4 are installed, further ensuring the reliability of the second control board 4.

[0065] Moreover, a second groove 113 is provided on the side of the male-end sheath 11 close to the female-end sheath 22, and a first groove 114 is provided on the side facing away from the female-end sheath 22, which can ensure uniform wall thickness around the plug-in protrusion 12 while reducing weight.

[0066] In some embodiments, one of the male-end sheath 11 and the plug-in protrusion 12 is provided with a mating groove 121 and the other is provided with a mating protrusion. The plug-in protrusion 12 and the male-end sheath 11 are fixedly connected and the mating protrusion cooperates with the mating groove 121.

[0067] Refer to Figure 1 As shown, if the plug-in protrusion 12 is provided with a mating groove 121, when the plug-in protrusion 12 is connected to the male-end sheath 11, the male-end sheath 11 is provided with a mating protrusion. The mating protrusion is not shown in the figure. The mating protrusion and the mating groove 121 cooperate and the male-end sheath 11 and the plug-in protrusion 12 are fixedly connected. The mating protrusion can be made of an elastic material, which is convenient for the mating connection between the mating groove 121 of the plug-in protrusion 12 and the mating protrusion. At the same time, after the two are mated, the plug-in protrusion 12 is fixedly connected to the male-end sheath 11, thereby improving the stability and reliability of the plug-in protrusion 12 connected within the male-end sheath 11 and avoiding the problem that the plug-in protrusion 12 may become loose and detached from the male-end sheath 11 due to long-term use.

[0068] In some embodiments, there are multiple plugging protrusions 12, and the plugging slots 221 of the female connector 2 are provided in multiple numbers. The multiple plugging protrusions 12 are respectively plugged into the multiple plugging slots 221 one by one.

[0069] In practice, for example, the distance between two adjacent plugging protrusions 12 is set to 7 mm, and of course it can also be 6 mm, 5 mm, etc. Moreover, the plugging protrusions 12, the plugging slots 221 and the clamping members 21 can be provided in two, four, six, etc. In the embodiment of the present invention, the plugging protrusions 12, the plugging slots 221 and the clamping members 21 are all set to four. At this time, it can not only meet the requirement of appropriate high-current transmission, but also save space. For example, the length and width of a single plugging protrusion 12 are about 7.5 mm×9.5 mm at least.

[0070] That is, through the plugging of the multiple plugging protrusions 12 and the multiple plugging slots 221 in one-to-one correspondence. For example, when each plugging protrusion 12 is in clamping fit with each clamping member 21, a group of current transmission paths is formed. Then, the cooperation of the multiple plugging protrusions 12 and the multiple clamping members 21 forms multiple groups of current transmission paths, which can simultaneously meet the transmission requirements of high voltage and large current in multiple circuits.

[0071] Moreover, due to the arrangement of the first elastic piece 211 and the second elastic piece 212, when the multiple plugging protrusions 12 and the multiple clamping members 21 deviate slightly along the first direction, since the first elastic piece 211 and the second elastic piece 212 have certain elasticity, the plugging protrusion 12 can still be plugged between the first elastic piece 211 and the second elastic piece 212 and be in contact fit with the first elastic piece 211 and the second elastic piece 212 to ensure the electrical connection between the plugging protrusion 12 and the clamping member 21.

[0072] Further, there is one male-end sheath 11 in the embodiment of the present invention. When there are four plugging protrusions 12, the one male-end sheath 11 is provided with four connection ports 112. Each plugging protrusion 12 is connected to one connection port 112, and the four plugging protrusions 12 share one male-end sheath 11, so as to reduce the volume of the male-end sheath 11 and save space. Similarly, the four clamping members 21 share one female-end sheath 22, which also saves the volume of the female-end sheath 22, thus saving the volume after the connection of the male connector 1 and the female connector 2 and occupying less space.

[0073] In addition, it should be noted that in the first control board 3 and the second control board 4 of the embodiment of the present utility model, the board-to-board connection method through the connector 100 is such that the male end 1 of the connector is welded to the second control board 4 by means of reflow soldering at the end of the insertion protrusion 12, and the connection pins 2133 of the female end 2 of the connector are welded to the first control board 3 by means of reflow soldering. Different from the large-current connectors 100 on the market that require plug-in wave soldering or manual soldering, this connector 100 meets the requirements of surface mount reflow soldering and can be used for both SMT surface mounting and DIP plug-in installation. DIP plug-in installation is used to install components with dual in-line package. SMT surface mounting is a circuit assembly technology in which leadless or short-lead surface-mounted components are installed on the surface of a printed circuit board or other substrates and are welded and assembled by methods such as reflow soldering or dip soldering.

[0074] The embodiment of the present utility model also discloses a vehicle, including the above-mentioned connector. This connector can be applied to in-vehicle power supplies, motor controllers, powertrains, battery packs, etc. on the vehicle. By applying this connector to vehicle electrical connections, the reliability and stability of the connections are improved, thereby enhancing the user experience of the vehicle.
