[0051] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0052] Example 1

[0053] Please see Figures 1 to 8 The connector assembly 100 provided in the first embodiment of this utility model includes a male connector end 10, a female connector end 20, and an elastic element 30.

[0054] The male connector 10 includes a first circuit board 11 and a plurality of plugs 12 disposed on the first circuit board 11. The plurality of plugs 12 are spaced apart along the X direction. The first circuit board 11 is used to fix it to the first external structure. The female connector 20 includes a second circuit board 21 and a plurality of contacts 22 disposed on the second circuit board 21. Each contact 22 is provided with a slot 23. One contact 22 and one plug 12 are correspondingly inserted and mated. One plug 12 is inserted into one slot 23 along the Y direction. The second circuit board 21 is used to fix it to the second external structure. The elastic member 30 is used to apply an elastic force to the contact 22, or to be electrically connected to the contact 22 and to abut against the plug 12 to realize the electrical connection between the plug 12 and the contact 22.

[0055] The connector assembly 100 described above uses multiple plugs 12 and multiple contacts 22. Each plug 12 and contact 22 is electrically connected. The stability of the electrical connection is ensured by the interlocking of multiple plugs 12 and multiple contacts 22. Specifically, during insertion, the plug 12 is inserted into the slot 23 along the Y direction, which facilitates the insertion operation. At the same time, the elastic element 30 is provided. The elastic element 30 applies an elastic force to the contact 22 or directly contacts the plug 12, which further ensures the stability of the electrical connection. After the plugs 12 and contacts 22 are connected, the communication connection between the first circuit board 11 and the second circuit board 21 is also realized. For example, when the male connector 10 is installed on the drone end (i.e., the first external structure is the drone) and the female connector 20 is installed on the battery end (i.e., the second external structure is the battery end), after the electrical connection between the male connector 10 and the female connector 20 is realized, power can be supplied to the drone, so that the drone can fly.

[0056] Understandably, in this embodiment, the slot 23 extends along the Y direction. When the male connector 10 and the female connector 20 are connected, the female connector 20 and the male connector 10 are driven to move relative to each other and approach each other along the Y direction, thereby inserting the plug 12 into the slot 23. This achieves the mating of the male connector 10 and the female connector 20. In other embodiments, the male connector 10 and the female connector 20 can also be connected in a relative insertion manner as needed.

[0057] Please see Figure 5 and Figure 6 In one embodiment of this utility model, since the male connector 10 and the female connector 20 are connected in a manner that brings them close together along the Y direction, in order to improve the accuracy of the connection between the male connector 10 and the female connector 20, the male connector 10 includes an odd number of plugs 12 and the female connector 20 includes an odd number of contacts 22, and the number of plugs 12 and contacts 22 are both ≥3. Thus, by setting an odd number of plugs 12 and an odd number of contacts 22, the number of positive and negative poles formed by the contacts 22 is not equal, that is, the number of positive poles can be one more than the number of negative poles, or the number of negative poles can be one more than the number of positive poles. In this way, the extra positive or negative pole serves as a identification and error prevention function. When the male connector 10 and the female connector 20 are connected in the Y direction, it is not necessary to distinguish between positive and negative poles, and the electrical connection between the male connector 10 and the female connector 20 can be quickly achieved.

[0058] Understandably, multiple positive electrodes are connected in parallel, and multiple negative electrodes are also connected in parallel.

[0059] Specifically, this embodiment includes three plugs 12 and three contacts 22. Along the X-direction, the two on either side are negative terminals, and the one in the middle is positive. By using three plugs, not only is identification achieved, but the installation of the male connector 10 and female connector 20 is also facilitated, ensuring installation efficiency. This also avoids an excessively large and bulky structure. In other embodiments, the number of plugs 12 and contacts 22 can be adjusted according to the stability requirements of the connection.

[0060] Please refer to Figure 2 and Figure 8 To ensure connection stability, the plug 12 and the contact 22 have sufficient contact area. The contact 22 and the plug 12 extend in the Y direction to ensure a certain extension length, thereby ensuring contact stability. Furthermore, to improve the convenience of inserting the plug 12 and the contact 22 in the Y direction, the contact 22 is provided with a contact rib 221 extending in the Y direction. Thus, by setting the contact rib 221, the height of the contact rib 221 in the Z direction is less than the height of the contact 22 in the Z direction, and the contact area between the contact rib 221 and the plug 12 is less than the contact area between the contact rib 221 and the plug 12. The electrical connection between the contact rib 221 and the plug 12 is achieved by the contact rib 221 being smaller than the contact area between the contact rib 221 and the plug 12, ensuring that the contact rib 221 is always in contact with the plug 12, thereby ensuring the stability of the electrical connection and ensuring that the contact rib 221 is always in contact with the plug 12. Understandably, by setting the contact ribs 221, the structural strength of the entire contact element 22 can also be increased.

[0061] In one embodiment, to ensure the stability of the electrical connection between the contact 22 and the plug 12, multiple contact ribs 221 arranged side-by-side along the Z direction can be provided on the contact 22, such as... Figure 8 As shown, by arranging multiple contact ribs 221, at least one contact rib 221 can be in contact with the plug 12, thereby ensuring the stability of the electrical connection.

[0062] Furthermore, in order to facilitate the insertion of the plug 12 into the slot 23, the end of the contact rib 221 in this embodiment has a guide slope 222 along the Y direction. That is, the thickness of the contact rib 221 along the X direction is different, and the thickness of the end along the X direction gradually decreases away from the center of the contact rib 221, thereby forming the guide slope 222 at the end, so that the plug 12 can be pushed in along the guide slope 222, and also reducing the risk of collision between the plug 12 and the end of the contact rib 221.

[0063] Understandably, since the slot 23 of this embodiment passes through the contact member 22 in the Y direction, the contact rib 221 is provided with guide slopes 222 at both ends in the Y direction to facilitate the insertion of the plug 12 along each end of the slot 23.

[0064] Please see Figures 4 to 6 In this embodiment, the elastic element 30 is a spring. One end of the spring abuts against the second external structure, and the other end abuts against the contact element 22 to apply an elastic force along the X direction to the contact element 22, thereby pressing the contact element 22 onto the plug 12 and ensuring the stability of the electrical connection between the contact element 22 and the plug 12. In other embodiments, the elastic element 30 can also be set as a spring-type elastic structure, which can also achieve the effect of applying an elastic force to the contact element 22.

[0065] Further, please refer to Figure 7 When the elastic element 30 is set as a spring, since the spring is cylindrical, in order to position and guide the installation of the spring, the contact element 22 is provided with a positioning post 223, and the elastic element 30 is sleeved on the positioning post 223. In this way, the installation position of the spring can be restricted by the setting of the positioning post 223, and the extension and contraction of the spring can be guided.

[0066] Please refer to Figures 1 to 3 In this embodiment, the first installation structure can be unmanned, with the male connector 10 mounted on the surface of the drone. The second installation structure can be a battery compartment 200. Specifically, the compartment body 210 mounted on the battery compartment 200 has a corresponding through groove 220 for the slot 23. The through groove 220 extends along the Y direction and extends to the edge of the compartment body 210 so that the plug 12 can be inserted into the battery compartment 200 along the Y direction.

[0067] Understandably, at this time, one end of the elastic member 30 abuts against the inner wall of the chamber 210, that is, the top wall of the chamber 210 extends into the direction of the bottom wall to form an abutment wall 240. An abutment wall 240 is provided between every two contact members 22. The elastic member abuts against the abutment wall 240, and the other end abuts against the contact member 22, thereby realizing the installation of the elastic member.

[0068] Please see Figures 5 to 8 In this embodiment, the contact element 22 includes two sub-rows 224 arranged opposite each other along the X direction. The gap between the two sub-rows 224 is a slot 23. The housing 210 is provided with multiple notches 230, each notch 230 is connected to a corresponding through slot 220, and each sub-row 224 is inserted into a notch 230. Figure 2 As shown, this allows the plug to be exposed relative to the through slot 220, so that after the plug 12 is inserted into the through slot 220, it can be electrically connected to each sub-bar 224.

[0069] Specifically, please refer to Figure 7 and Figure 8 Each sub-row 224 includes a main body 2241 and snap-fit ​​portions 2242 located at both ends of the sub-row 224 along the Y direction. Positioning posts 223 and contact ribs 221 are installed on the main body 2241. The snap-fit ​​portions 2242 are used to snap onto the compartment 210. At the same time, the contact ribs 221 on the main body 2241 can be exposed in the through groove 220 along the X direction. Specifically, in order to enable the main body 2241 to be exposed in the notch 230, the snap-fit ​​portion 2242 includes a bent section 2243, a first abutting section 2244 and a second abutting section 2245. The bent section 2243 and the main body 2241 are set at an obtuse angle. The first abutting section 2244 and the second abutting section 2245 are set perpendicularly to each other and are used to abut against the inner wall of the compartment 210, thereby enabling the sub-row 224 to be snapped into the notch 230.

[0070] In this embodiment, the plug 12 can be made of metal; the contact 22 can be made of copper alloy, such as copper, brass, or beryllium copper, to ensure sufficient overcurrent capacity. Specifically, in this embodiment, the contact 22 is made of beryllium copper. Since the plug 12 and the contact 22 will undergo multiple insertion and removal processes, there is friction between them. By using beryllium copper, the wear resistance between them is ensured.

[0071] In this embodiment, the sub-row 224 further includes a plug-in section 2246, which is plugged into the second circuit board 21 to achieve the positioning and installation of the sub-row 224 and the second circuit board 21.

[0072] The connector assembly 100 described above, by providing a slot 23 extending along the Y direction on the contact 22, allows the connector 12 to be inserted into the slot 23 when it is plugged into the male connector 10, as the two move relative to each other along the Y direction. This ensures that the female connector 20 can be plugged into the slot 23 regardless of which end of the female connector 20 faces the plug 12 along the Y direction. By setting the plug 12 and the contact 22 to an odd number of configurations, an additional positive or negative terminal is provided for identification and error prevention. When the male connector 10 and the female connector 20 are plugged into each other along the Y direction, there is no need to distinguish between the positive and negative sides, which can quickly achieve electrical connection between the male connector 10 and the female connector 20, improving the convenience of plugging into the connection. By providing a contact rib 221 on the contact 22, the contact rib 221, which is shorter in height along the Z direction, can contact the plug 12 to achieve electrical connection, improving the stability of the electrical connection.

[0073] Example 2

[0074] Please see Figures 9 to 14The connector assembly 100 provided in the second embodiment of this utility model also includes a male connector 10, a female connector 20, and an elastic element 30.

[0075] The connector assembly 100 in this embodiment has the same features as the connector assembly 100 in the first embodiment: the contact 22 forms a slot 23 extending in the Y direction. By driving the female connector end 20 and the male connector end 10 to move relative to each other in the Y direction to bring them closer together, the plug 12 is inserted into the slot 23, thereby realizing the mating of the male connector end 10 and the female connector end 20.

[0076] Meanwhile, the male connector 10 also includes an odd number of plugs 12, and the female connector 20 includes an odd number of contacts 22. The number of plugs 12 and contacts 22 are both set to ≥3. In this way, by setting an odd number of plugs 12 and an odd number of contacts 22, the number of positive and negative poles are not equal. That is, the number of positive poles can be one more than the number of negative poles, or the number of negative poles can be one more than the number of positive poles. Thus, the extra positive or negative pole serves as a identification and foolproof function. When the male connector 10 and the female connector 20 are plugged in along the Y direction, there is no need to distinguish between the positive and negative sides, and the electrical connection between the male connector 10 and the female connector 20 can be quickly achieved.

[0077] Specifically, in this embodiment, three plugs 12 and three contacts 22 are provided. Along the X-direction, the two on either side are negative, and the one in the middle is positive. By setting the number to three, not only is identification achieved, but the installation of the male connector 10 and female connector 20 is also facilitated, ensuring installation efficiency. This also avoids an excessively large and bulky structure. In other embodiments, other numbers of plugs 12 and contacts 22 can be provided according to the stability requirements of the connection.

[0078] The connector assembly 100 in this embodiment differs from the connector assembly 100 in Embodiment 1 in that the contact 22 in this embodiment is an integral structure, and the slot 23 is formed within the contact 22 itself. Thus, by setting the contact 22 to be an integral structure, it is easier to form the contact 22.

[0079] Furthermore, in this embodiment, the elastic element 30 is a spring arm, which is connected to the contact element 22 and abuts against the plug 12 to achieve an electrical connection between the plug 12 and the contact element 22. That is, the contact element 22 is provided with a slot 23. After the plug 12 is inserted into the slot 23, since the plug 12 has a certain thickness in the X direction, it slightly squeezes the spring arm to deform it. Since the spring arm has a tendency to return to its original shape, an elastic force is generated, thereby achieving a stable abutment of the spring arm against the plug 12, and realizing an electrical connection between the contact element 22 and the plug 12.

[0080] When setting the spring arms, one, two, or more can be set. Understandably, when setting one spring arm, the smaller number of spring arms facilitates their forming on the contact element 22; when setting multiple spring arms, at least one spring arm is guaranteed to contact the plug 12, ensuring the stability of the electrical connection. Furthermore, by setting multiple spring arms compared to a single spring arm, the contact area between each spring arm and the contact element 22 is smaller, facilitating deformation under the pressure of the plug 12, thus facilitating the insertion of the plug 12. Moreover, with multiple spring arms, the contact area between the spring arm and the plug 12 is smaller than that with only one spring arm, ensuring stable contact with the plug 12.

[0081] Specifically, in this embodiment, two spring arms are provided. Too few spring arms would compromise the stability of contact with the plug 12, while too many spring arms would result in a small connection area between each spring arm and the contact 22, affecting the connection strength. In other embodiments, the number of spring arms can be adjusted according to the structural size of the connector assembly 100.

[0082] In this embodiment, to enhance the structural strength of the contact element 22 and improve its molding efficiency, the elastic element 30 and the contact element 22 are integrally formed, avoiding the need for subsequent connection steps. The absence of connection points between them increases the overall contact strength of the contact element 22, while also improving molding efficiency and reducing production costs. In other embodiments, since the spring arm has a curved structure, it can be molded independently to facilitate its own molding structure, and then connected to the contact element 22 later.

[0083] In this embodiment, the material of the contact 22 can be the same as that of the contact 22 in Embodiment 1, that is, beryllium copper, thereby ensuring the wear resistance of the contact 22. Specifically, when molding the integrally formed contact 22 and elastic member 30, the beryllium copper part is stamped to form the contact 22 and elastic member 30 of this embodiment.

[0084] Further, please refer to Figure 9 , Figure 10 and Figure 12 To reduce the possibility of intermittent connection during drone flight due to shaking, the plug 12 includes multiple male connectors 121 arranged in parallel along the Y direction, and the multiple male connectors 121 are connected in parallel sequentially. The contact 22 includes multiple female connectors 225 arranged in parallel along the Y direction, and the multiple female connectors 225 are connected in parallel sequentially. Each female connector 225 forms a slot, and the multiple slots form a slot 23. A male connector 121 is inserted into a corresponding slot. In this way, by setting each plug 12 to include multiple male connectors 121 and each contact 22 to include female connectors 225, and by connecting the male connectors 121 and female connectors 225 in parallel sequentially, at least one male connector 121 can be electrically connected to its corresponding female connector 225, avoiding intermittent connection and ensuring the stability of the electrical connection between the drone and the battery compartment 200.

[0085] The number of male and female connectors 121 and 225 can be set as needed. For example, the current carrying capacity of one female connector 225 is 50A, and the total current carrying capacity of two female connectors 225 is 100A. Similarly, the number of male and female connectors 121 and 225 can be set differently according to the total current carrying capacity.

[0086] Specifically, in this embodiment, each contact 22 includes three female and male connection ends 225, and each plug 12 includes three male connection ends 121, which not only ensures the current carrying capacity, but also facilitates the installation of the entire connector assembly 100.

[0087] Specifically, please refer to the figure. The mother-child connection end 225 of this embodiment includes a first electrically conductive part 2251, a connecting part 2252 and a second electrically conductive part 2253 connected in sequence. The connecting part 2252 is connected to the second circuit board 21. The first electrically conductive part 2251 and the second electrically conductive part 2253 are arranged opposite to each other and are both connected with elastic members 30. In this way, each mother-child connection end 225 is configured to include the first electrically conductive part 2251, the connecting part 2252 and the second electrically conductive part 2253 integrally formed. For example, the mother-child connection end 225 can be formed by stamping, which can reduce the forming difficulty of the mother-child connection end 225, improve production efficiency and reduce production costs.

[0088] Understandably, both the first electrically conductive part 2251 and the second electrically conductive part 2253 are provided with through holes 2254, and the elastic member 30 is connected to the hole wall of the through hole 2254 to realize the connection of the elastic member 30 on the female-female connection end 225.

[0089] Please see Figure 10 and Figure 11 In this embodiment, when the connecting part 2252 is connected to the second circuit board 21, the second circuit board 21 is provided with a locking hole 211, and the female-child connection end 225 also includes a locking block 2255, which is locked in the locking hole 211. In this way, the female-child connection end 225 is installed on the second circuit board 21 by locking.

[0090] Specifically, the locking block 2255 in this embodiment includes a bent section a and two opposing locking sections b disposed on the bent section a. The bent section a is connected to the connecting part 2252 and bends away from the first electrical conduction part 2251 and the second electrical conduction part 2252. The two locking sections b are inserted into the locking hole 211, which is equivalent to forming a locking claw at the end of the locking block 2255. That is, by setting the locking claw, since the locking claw is easily deformed under the pressure of external force, it can be inserted into the locking hole 211 through the deformed locking claw. After the external force is lost, the locking claw returns to its original shape and abuts against the inner wall of the locking hole 211, so as to realize the installation of the mother-child connection end 225 on the second circuit board 21.

[0091] In this embodiment, two snap-fit ​​segments b are provided, which are arranged side by side along the X direction. Under the drive of external force, the snap-fit ​​segments b deform and snap into the snap-fit ​​hole 211. After the external force is removed, the two snap-fit ​​segments b move away from each other to be locked in the snap-fit ​​hole 211.

[0092] Furthermore, to ensure the stability of the snap-fit, the outer wall of the snap-fit ​​section b is provided with serrations c. The serrations c contact the wall of the snap-fit ​​hole 211, increasing the friction with the wall of the snap-fit ​​hole 211 and reducing the risk of loosening.

[0093] Understandably, in order to avoid loose connections, each male connector 121 can be soldered onto the first circuit board 11, or installed by riveting or bolting. Correspondingly, each female connector 225 can also be further installed onto the second circuit board 21 by soldering. Since the connection strength of soldering is high, it avoids loosening.

[0094] Furthermore, after the male end 10 and the female end 20 of the connector are plugged in, they are electrically connected, and the first circuit board 11 and the second circuit board 21 are also connected in communication, so that information such as power can be transmitted to the first circuit board 11.

[0095] Furthermore, since multiple female-to-female connectors 225 need to be installed on the second circuit board 21 along the Y direction, in order to facilitate the installation of multiple female-to-female connectors 225 on the second circuit board 21, the connecting part 2252 is provided with a locking block 2255 at both ends along the Y direction. Along the X direction, the width of the locking block 2255 at one end is greater than the width of the locking block 2255 at the other end, so that the installation position of the female-to-female connectors 225 on the second circuit board 21 along the Y direction can be quickly identified, so that the locking block 2255 with a larger width faces the same end, and the locking block 2255 with a smaller width faces the other end, which facilitates the sequential installation of multiple female-to-female connectors 225 on the second circuit board 21 along the Y direction, and makes the orientation of the spring arm consistent.

[0096] Further, please refer to Figure 13 and Figure 14 To prevent the contact 22 from becoming loose relative to the second circuit board 21 due to repeated insertion and removal of the plug 12 in the slot 23, the connecting part 2252 is provided with a first connecting hole 2257, and the second circuit board 21 is provided with a second connecting hole 212. The first connecting hole 2257 and the second connecting hole 212 are connected by bolts. By providing the first connecting hole 2257 and the second connecting hole 212, the user can tighten screws on the contact 22 and the second circuit board 21 as needed to ensure the tightness of the connection.

[0097] Understandably, in order to facilitate the insertion of the male connector into the slot formed by the female connector 225, the female connector 225 is provided with at least two guide ribs 2258 arranged along the Y direction, and along the Y direction, each side of the spring arm is provided with a guide rib 2258. Specifically, in this embodiment, the first electrical conduction part 2251 and the second electrical conduction part 2253 are both provided with guide ribs 2258, and each of the first electrical conduction part 2251 and the second electrical conduction part 2253 is provided with two guide ribs 2258. Each side of the spring arm is provided with a guide rib 2258. Since the male connector 121 can be inserted into both sides of the female connector 225 along the Y direction, the way that guide ribs 2258 are provided on both sides of the spring arm facilitates the pushing in of the male connector 121.

[0098] In this embodiment, the guide rib 2258 and the male-female connection end 225 are integrally formed, that is, the guide rib 2258 is formed by stamping the body of the male-female connection end 225. It can be understood that in order to realize the guiding function of the guide rib 2258, the guide rib 2258 has inclined surfaces on both sides along the Y direction, thereby guiding the insertion of the male-female connection end 121.

[0099] In this embodiment, the connector assembly 100 can be used in the same way as the connector assembly 100 in Embodiment 1. The first mounting structure in this embodiment can be the shell of a drone, with the male connector end 10 mounted on the surface of the drone. The second mounting structure can be the battery compartment 200's body 210. The body 210 has a corresponding through slot 220 for the slot 23, extending along the Y direction to the edge of the body 210, allowing the plug 12 to be inserted into the battery compartment 200 along the Y direction. It is understood that after the male connector end 10 and the female connector end 20 of this embodiment are connected, the first circuit board 11 and the second circuit board 21 achieve a communication connection.

[0100] The connector assembly 100 described above simplifies the molding of the entire contact 22 by setting the elastic element 30 as a spring arm, which is directly molded onto the contact element 22, eliminating the need for additional structures to generate elastic force. Furthermore, by configuring the plug 12 to include multiple male connector ends 121 arranged in parallel along the Y direction, with the multiple male connector ends 121 connected in parallel sequentially, and the contact element 22 to include multiple female connector ends 225 arranged in parallel along the Y direction, with the multiple female connector ends 225 connected in parallel sequentially, at least one male connector... The connector 121 can be electrically connected to the corresponding mother-daughter connector 225 to avoid a loose connection, thereby ensuring the stability of the electrical connection between the drone and the battery compartment 200. By providing a first connection hole 2257 on the mother-daughter connector 225 and a second connection hole 212 on the second circuit board 21, the locking member can be selectively passed through the first connection hole 2257 and the second connection hole 212 to lock the mother-daughter connector 225 and the second circuit board 21 again, ensuring the installation stability of the mother-daughter connector 225.
