[0037] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Please refer to Figure 1 , an electrical connector includes a first connector 100 and a second connector 200 .

[0039] Please refer to Figure 4 and Figure 5 The first connector 100 includes a first housing 110 and a first connection terminal 120 mounted on the first housing 110 , and an end of the first connection terminal 120 has a first contact plane 121 .

[0040] Please refer to Figure 7 and Figure 8 The second connector 200 includes a fixing member 210, a second shell 220, a second connecting terminal 230 and an elastic push shell member 240. The second connecting terminal 230 is installed on the second shell 220. The end of the second connecting terminal 230 away from the fixing member 210 has a second contact plane 231. The second shell 220 is slidably installed on the fixing member 210. The elastic push shell member 240 is arranged between the fixing member 210 and the second shell 220. The elastic push shell member 240 is used to apply a force to the second shell 220 away from the fixing member 210.

[0041] Among them, please refer to Figures 1 to 3 The second shell 220 can be detachably connected to the first shell 110 so that the second contact plane 231 contacts the first contact plane 121.

[0042] In the electrical connector provided by the present invention, the first connection terminal 120 and the second connection end adopt a planar contact method, rather than a barb to achieve mutual hook connection, so as to facilitate the user to perform plugging and unplugging operations. In addition, when the first connector 100 and the second connector 200 are connected to each other, the elastic shell push member 240 applies a force to the second shell 220 away from the fixing member 210, thereby pressing the second shell 220 and the second connection terminal 230 installed on the second shell 220 onto the first connector 100, so that the first connection terminal 120 and the second connection terminal 230 can be in close and good contact, so that the above-mentioned electrical connector has good contact performance, and solves the technical problem that the existing electrical connector with good contact is inconvenient to use.

[0043] In addition, when the first connector 100 and the second connector 200 need to be connected to each other, the elastic shell pusher 240 applies a force to the second housing 220 away from the fixing member 210, which can push the second housing 220 and the first housing 110 closer and connected, so that the user only needs to apply a small additional force to connect the first connector 100 and the second connector 200. When the first connector 100 and the second connector 200 need to be separated, since the user only needs to apply a small force during the connection process to connect the first connector 100 and the second connector 200, the user can also pull out the second connector 200 without much effort.

[0044] Therefore, the electrical connector provided by the present invention is more convenient and labor-saving to plug and unplug, allowing the connection and separation of the first connector 100 and the second connector 200 to be freer and faster, providing an excellent user experience of connector connection and separation, and conforming to ergonomic design.

[0045] Optionally, the first connection terminal 120 includes at least one of a first power terminal 125 and a first signal terminal 126. Figure 4 As shown, the first connection terminal 120 includes a first power terminal 125 and a first signal terminal 126 .

[0046] Optionally, the second connection terminal 230 includes at least one of a second power terminal 232 and a second signal terminal 233. Figure 8 As shown, the second connection terminal 230 includes a second power terminal 232 and a second signal terminal 233 .

[0047] In some embodiments, in combination Figure 1 , Figure 4 and Figure 7, the first connection terminal 120 includes a plurality of first power terminals 125. The specifications of the plurality of first power terminals 125 are the same, and the second connection terminal 230 includes a second power terminal 232 corresponding to the first power terminals 125. In this way, the user can arbitrarily install the plurality of first power terminals 125 relatively to the first housing 110 without deliberately distinguishing the installation position corresponding to any one of the first power terminals 125, so as to avoid the phenomenon that when the specifications of the first power terminals 125 are different, it is necessary to deliberately distinguish the installation position on the first housing 110, causing installation inconvenience.

[0048] Similarly, there is no need to deliberately distinguish the installation position of the second power terminal 232 on the second housing 220 .

[0049] In addition, the first connecting terminal 120 and the second connecting terminal 230 are in close contact through the first contact plane 121 and the second contact plane 231. The planar contact is conducive to the transmission of large currents. Therefore, the electrical connector provided by the present invention has a high current carrying capacity. Under the same current carrying requirements, the volume can be made smaller, which meets the design requirements of small volume and large current, and is more energy-saving and environmentally friendly.

[0050] Specifically, see Figure 1 , multiple first power terminals 125 are arranged in a matrix. For example, multiple first power terminals 125 are distributed in a ring, line or square matrix. Multiple first power terminals 125 with the same specifications and arranged in a matrix can be symmetrically distributed about a certain center line. When the first shell 110 and the second shell 220 are connected, the user does not need to deliberately align the connection position, that is, the above-mentioned electrical connector has a blind guide function, which is convenient for connection.

[0051] In some embodiments, in combination Figure 1 , Figure 4 and Figure 7 The first connection terminal 120 includes a first signal terminal 126, and the specifications of the plurality of first signal terminals 126 are the same. The second connection terminal 230 includes a second signal terminal 233 corresponding to the first signal terminal 126. In this way, the user can arbitrarily install the plurality of first signal terminals 126 on the first housing 110 in a relative manner without deliberately distinguishing any first signal terminal 126 and its corresponding installation position, so as to avoid the phenomenon that when the specifications of the first signal terminals 126 are different, it is necessary to deliberately distinguish the installation positions on the first housing 110, causing installation inconvenience.

[0052] Similarly, there is no need to deliberately distinguish the installation position of the second signal terminal 233 on the second housing 220 .

[0053] Specifically, see Figure 1, multiple first signal terminals 126 are arranged in a matrix. For example, multiple first signal terminals 126 are distributed in a ring, line or square matrix. Multiple first signal terminals 126 with the same specifications and arranged in a matrix can be symmetrically distributed about a certain center line. When the first shell 110 and the second shell 220 are connected, the user does not need to deliberately align the connection position, that is, the above-mentioned electrical connector has a blind guide function, which is convenient for connection.

[0054] In some embodiments, see Figure 1 The first housing 110 has a first mounting hole 113 for mounting on a device or a power supply, so that the first connector 100 can be mounted on the device or the power supply, so that the device or the power supply can transmit current and / or signals through the electrical connector provided by the present invention.

[0055] Specifically, the first connector 100 is installed on a device or a power source by passing the first fastener 320 through the first mounting hole 113 .

[0056] In some embodiments, see Figure 1 The fixing member 210 has a second mounting hole 211 for mounting on a device or a power supply, so that the second connector 200 can be mounted on the device or the power supply, so that the device or the power supply can realize the transmission of current and / or signals through the electrical connector provided by the present invention.

[0057] Specifically, the second connector 200 is installed on a device or a power source by passing through the second fastener 330 on the second mounting hole 211 .

[0058] In some embodiments, see Figure 2 , Figure 3 and Figure 5 The first connector 100 also includes a first cover plate 130 and an elastic pushing terminal piece 140. The first cover plate 130 is installed on the first shell 110 and is located on the side of the first shell 110 away from the second shell 220. The elastic pushing terminal piece 140 is arranged between the first cover plate 130 and the first connecting terminal 120. The elastic pushing terminal piece 140 is used to apply a force to the first connecting terminal 120 to approach the second connecting terminal 230.

[0059] Since the elastic push terminal member 140 is used to apply a force to the first connection terminal 120 to approach the second connection terminal 230, when the first connector 100 and the second connector 200 are connected, not only the elastic push shell member 240 pushes the second connection terminal 230 and the first connection terminal 120 to be in close contact, but also the elastic push terminal member 140 simultaneously pushes the first connection terminal 120 and the second connection terminal 230 to be in close contact, thereby ensuring that the first contact plane 121 and the second contact plane 231 are in close contact. Therefore, the electrical connector provided by the present invention has good contact performance.

[0060] In addition, when the first connector 100 and the second connector 200 need to be connected to each other, the elastic push terminal 140 applies a force to the first connection terminal 120 to approach the second connection terminal 230, and also pushes the first housing 110 to connect with the second housing 220. Similarly, when the first connector 100 and the second connector 200 need to be separated, the user can separate the first connector 100 and the second connector 200 without much effort.

[0061] Please refer to Figures 4 to 6 When the first connection terminal 120 includes the first power terminal 125 and the first signal terminal 126, the elastic push terminal member 140 includes a first push terminal member 141 and a second push terminal member 142. The first push terminal member 141 applies a force to the first power terminal 125 to approach the second connection terminal 230, and the second push terminal member 142 applies a force to the first signal terminal 126 to approach the second connection terminal 230.

[0062] Specifically, the elastic push terminal 140 can be a spring, a memory alloy or a magnet, etc. For example, the elastic push terminal 140 is two sets of mutually exclusive magnets, one set of magnets is mounted on the first cover plate 130 , and the other set of magnets is mounted on the first connection terminal 120 .

[0063] In some embodiments, please refer to Figures 4 to 6 The first housing 110 has a first terminal hole 111, the first cover plate 130 has a first through hole 131, and the first connection terminal 120 includes a contact portion 122, a flange 123 and a connection portion 124 arranged in sequence, and the end of the contact portion 122 away from the flange 123 has a first contact plane 121. The contact portion 122 is installed in the first terminal hole 111, and the connection portion 124 is penetrated in the first through hole 131. The elastic push terminal 140 is sleeved on the connection portion 124, one end of the elastic push terminal 140 abuts against the first cover plate 130, and the other end of the elastic push terminal 140 abuts against the flange 123. The elastic push terminal 140 is located between the first cover plate 130 and the flange 123, thereby pressing the flange 123 and the contact portion 122. The contact portion 122 can be stably located in the first terminal hole 111 and will not retreat, ensuring that when the first connector 100 and the second connector 200 are connected, the first contact plane 121 and the second contact plane 231 maintain close contact, and the contact portion 122 will not retreat due to the pressure of the second connecting terminal 230, and the phenomenon of poor contact between the first contact plane 121 and the second contact plane 231 will not occur.

[0064] Specifically, please refer to Figures 4 to 6When the first connection terminal 120 includes a first power terminal 125 and a first signal terminal 126, correspondingly, the first terminal hole 111 of the first shell 110 includes a first power mounting hole 1111 for mounting the first power terminal 125 and a first signal mounting hole 1112 for mounting the first signal terminal 126, and the first through hole 131 of the first cover plate 130 includes a power through hole 1311 for connecting the first power terminal 125 to the outside and a signal through hole 1312 for connecting the first signal terminal 126 to the outside.

[0065] Specifically, combined Figures 4 to 6 The first cover plate 130 is detachably connected to the first shell 110 via a third fastener 330 .

[0066] In one embodiment, in combination Figure 5 The electrical connector further includes an elastic gasket 310, which is mounted on the end surface of the first housing 110 close to the second housing 220. In this way, when the first connector 100 and the second connector 200 are connected, the elastic shell push member 240 presses the second housing 220 against the first housing 110, and the elastic gasket 310 is located between the first housing 110 and the second housing 220, so that the first housing 110 and the second housing 220 can be connected more tightly.

[0067] In another embodiment, the elastic gasket 310 can also be installed on the end surface of the second shell 220 close to the first shell 110. Similarly, the elastic gasket 310 is located between the first shell 110 and the second shell 220, which can make the first shell 110 and the second shell 220 connected more tightly.

[0068] In some embodiments, please refer to Figures 7 to 9 , the second connector 200 further includes an elastic ring 250, the first housing 110 has a snap-fitting cavity 112, the second housing 220 has a protrusion 221 that can be embedded in the snap-fitting cavity 112, and the elastic ring 250 is sleeved on the outer wall of the protrusion 221. In this way, when the first connector 100 and the second connector 200 are connected, the elastic ring 250 is located between the outer wall of the protrusion 221 and the cavity wall of the snap-fitting cavity 112, which can make the first housing 110 and the second housing 220 more tightly connected.

[0069] Optionally, the elastic ring 250 is a rubber ring.

[0070] Specifically, please refer to Figures 7 to 9 The outer wall of the protrusion 221 is provided with a ring installation groove 2211 for installing the elastic ring 250.

[0071] Specifically, please refer to Figure 6The buckle cavity 112 includes a working cavity 1121 and an introduction cavity 1122 which are arranged in sequence. The introduction cavity 1122 is closer to the protrusion 221 than the working cavity 1121. The flow area of ​​the introduction cavity 1122 is larger than the flow area of ​​the working cavity 1121. The introduction cavity 1122 guides the protrusion 221 to be installed in the working cavity 1121.

[0072] In some embodiments, please refer to Figure 6 and Figure 8 One of the first housing 110 and the second housing 220 is provided with a block 114, and the other of the first housing 110 and the second housing 220 is provided with a slot 224. The block 114 can be snapped into the slot 224. The first housing 110 and the second housing 220 are connected to each other through the cooperation of the block 114 and the slot 224.

[0073] Optionally, refer to Figure 6 and Figure 8 The first shell 110 is provided with a clamping block 114 , and the second shell 220 is provided with a clamping slot 224 .

[0074] It is understandable that in other embodiments, the first shell 110 and the second shell 220 may also be connected to each other by means of magnetism or bonding.

[0075] In one embodiment, in combination Figures 7 to 9 The second connector 200 further includes a wire mounting member 260. The second housing 220 has a second terminal hole 222 for mounting the second connection terminal 230. The wire mounting member 260 is mounted on the second housing 220. The wire mounting member 260 has a wire groove 261, which is connected to the second terminal hole 222. In this way, the cable is mounted in the wire groove 261 and is connected to the second connection terminal 230 mounted in the second terminal hole 222 along the wire groove 261.

[0076] Specifically, when the first connecting terminal 120 includes a first power terminal 125 and a first signal terminal 126, correspondingly, the second connecting terminal 230 includes a second power terminal 232 and a second signal terminal 233, and the second terminal hole 222 of the second shell 220 includes a second power mounting hole 2221 for mounting the second power terminal 232 and a second signal mounting hole 2222 for mounting the second signal terminal 233.

[0077] Specifically, when the first connection terminal 120 includes the first power terminal 125 and the first signal terminal 126 , the cable accordingly includes a power line 360 ​​and a signal line 370 , and the wire grooves 261 are correspondingly divided into two groups, one group of wire grooves 261 is used to install the power line 360 ​​, and the other group of wire grooves 261 is used to install the signal line 370 .

[0078] Optionally, the wire mount 260 is an injection molded part.

[0079] In this embodiment, the second shell 220 is slidably mounted on the fixing member 210 in an inseparable manner. For example, the fixing member 210 is provided with a sliding limiter to limit the sliding stroke of the second shell 220. The sliding mounting structure of the second shell 220 is located between the sliding limiter and the fixing member 210. The sliding mounting structure of the second shell 220 refers to a structure of the second shell 220 for slidingly mounting on the fixing member 210, such as the peripheral wall of the second through hole 225 described below. When the second shell 220 moves away from the fixing member 210 under the action of the elastic shell push member 240, the sliding limiter blocks the second shell 220 from continuing to slide, so that the second shell 220 cannot be separated from the fixing member. The separation here means that the interval between the second shell 220 and the fixing member 210 cannot be increased indefinitely. The second shell 220 is not necessarily directly slidably mounted on the fixing member 210, but can also be indirectly slidably mounted on the fixing member 210.

[0080] Specifically, combined Figures 7 to 9 The second connector 200 further includes a shell connector 270. The second shell 220 has a second through hole 225. The shell connector 270 includes a limit terminal 271 and a connecting rod 272 that are connected to each other. The connecting rod 272 passes through the second through hole 225 and is connected to the fixing member 210. The limit terminal 271 abuts against the periphery of the second through hole 225. The elastic shell push member 240 is sleeved on the connecting rod 272. The two ends of the elastic shell push member 240 respectively abut against the second shell 220 and the fixing member 210. Since the connecting rod 272 is provided on the second shell 220, the second shell 220 can slide along the connecting rod 272, but is limited by the limit terminal 271 and the fixing member 210, and will not slide out. In this way, the second shell 220 is slidably mounted on the fixing member 210 through the shell connector 270.

[0081] Optionally, the shell connector 270 is a screw, and the fixing member 210 is provided with a third through hole corresponding to the second through hole 225. One end of the screw passes through the second through hole 225 and the third through hole in sequence, and is threadedly connected to the nut on the side of the fixing member 210 away from the second shell 220.

[0082] Specifically, please refer to Figures 7 to 9 The second housing 220 is provided with a first limiting protrusion 223 around the second through hole 225, the fixing member 210 is provided with a second limiting protrusion 212 corresponding to the first limiting protrusion 223, one end of the elastic shell push member 240 is sleeved on the first limiting protrusion 223, and the other end of the elastic shell push member 240 is sleeved on the second limiting protrusion 212. In this way, the two ends of the elastic shell push member 240 are respectively limited by the first limiting protrusion 223 and the second limiting protrusion 212, ensuring that the position of the elastic shell push member 240 is relatively stable, that is, the force applied by the elastic shell push member 240 to the second housing 220 is also relatively stable.

[0083] In one embodiment, please refer to Figures 7 to 9 The second connector 200 includes a plurality of elastic push shell members 240, and the plurality of elastic push shell members 240 are evenly distributed along the circumference of the second shell 220, so that the second shell 220 is subjected to a greater, more uniform and stable force from the elastic push shell members 240, thereby ensuring that the first connection terminal 120 and the second connection terminal 230 maintain stable and close contact.

[0084] In one embodiment, please refer to Figure 8 The second connector 200 further includes a second cover plate 280. The second housing 220 has a cavity for accommodating the second connection terminal 230. The second cover plate 280 is installed in the cavity and has a through hole for the second connection terminal 230 to communicate with the first connector 100. The second cover plate 280 shields and protects the internal structure of the second housing 220.

[0085] Specifically, the second cover plate 280 is detachably mounted on the second housing 220 by means of a fourth fastener 350 .

[0086] In some embodiments, the elastic shell pusher 240 may be a spring, a memory alloy, or a magnet, etc. For example, the elastic shell pusher 240 is two sets of mutually repelling magnets, one set of magnets is mounted on the second shell 220, and the other set of magnets is mounted on the fixing member 210, so that the second shell 220 is pressed against the first shell 110 by magnetic force.

[0087] The first shell 110 is an insulating shell, and the second shell 220 is an insulating shell.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
