Description

Technical Field

[0001] This utility model belongs to the field of electrical connection technology, and in particular relates to a connector structure with high current signal transmission. Background Technology

[0002] Electrical connectors are essential components in electronic systems for achieving electrical interconnection. They are primarily used to connect various components and devices in a circuit, completing the closure and opening of the circuit. They typically consist of two parts: a plug (female) and a socket (male), capable of transmitting current or signals.

[0003] Power connectors used in fields such as new energy vehicles and drones need to carry high current transmissions. For example, Chinese patent document CN223079415U discloses a crimp-type high-current connector, which effectively solves the problems of existing connectors, such as numerous production steps, complex manufacturing processes, difficulty in process control, low production efficiency, inconvenience to production, high production costs, short creepage distances and electrical clearances at the two ends of the connector, high risk of short circuits, significant safety hazards, and poor product quality and unreliability. It includes a housing, two ends, and two wires; the rear end of the housing is provided with a partition; the front ends of the two ends are disposed in the housing and on both sides of the partition; one end of each of the two wires is crimped to the rear end of the corresponding terminal, the crimping joint having a hexagonal structure, and the two wires are located on both sides of the partition. The front end of the housing has an insertion cavity. Each terminal has a first contact portion, a first fixing portion, and a first connecting portion integrally formed and connected in sequence. The first contact portion extends forward into the insertion cavity, the first fixing portion is fixedly mounted on the housing, and the first connecting portion extends outward from the housing. The first connecting portion has a first positioning hole. The wire core at one end of the wire is placed in the first positioning hole and riveted to the outer side of the first connecting portion to form a hexagonal structure. By setting a partition at the rear end of the housing, the front ends of the two terminals are placed in the housing. The two terminals are set on both sides of the partition. One end of each wire is riveted to the rear end of the corresponding terminal, and the riveting point has a hexagonal structure. The two wires are set on both sides of the partition. This type of crimp-type high-current connector has fewer production steps, a simpler manufacturing process, and easier process control, effectively improving production efficiency, bringing convenience to production, and reducing production costs. Secondly, the use of hexagonal riveting wires in the terminals effectively improves the stability of the product connection, and the toughness and plasticity of the connection between the terminals and the wires are better.

[0004] For power transmission equipment, control signal transmission is required, thus necessitating a control signal connector. In the aforementioned patented solution, the high-current connector only provides current transmission functionality; to meet power control requirements, a signal control connector is also needed.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model with a high-current signal transmission connector, please refer to... Figure 1 and Figure 2 This embodiment features a high-current signal transmission connector, integrating high-current and signal transmission. This replaces the existing method of using two separate connectors, simplifying the structure and making assembly easier. Specifically, it includes a male connector 100 and a female connector 200 that can be plugged into each other.

[0035] Reference Figures 2 to 5 The female connector 200 includes a female base 210, a first electrical connector 220, and a first signal terminal 230. A first protrusion 211 and a second protrusion 212 extend from one side of the female base 210. Two first connection holes 213 are provided on the top side of the first protrusion 211, extending to the bottom of the female base 210. The first electrical connector 220 is housed within each first connection hole 213. One end of the first electrical connector 220 has a first insertion hole 221, and the other end is connected to a wire, which can be connected to an electrical output unit. Multiple second connection holes 214 extend from the top side of the second protrusion 212 to the bottom side of the female base 210. Each second connection hole 214 contains a first signal terminal 230. One end of the first signal terminal 230 has a second insertion hole 231, and the other end is connected to a signal line, which can be connected to a control circuit.

[0036] Reference Figure 2 , Figure 6 and Figure 7The male connector 100 includes a male socket 110, a second electrical connector 120, and a second signal terminal 130. The male socket 110 has a first recess 111 and a second recess 112 on one side. The bottom of the first recess 111 has two third connection holes 113, each containing a second electrical connector 120. One end of the second electrical connector 120 extends into the first recess 111, and the other end passes through the third connection hole 113, and is used to connect a wire. The bottom of the second recess 112 has multiple fourth connection holes 114, each containing a second signal terminal 130. One end of the second signal terminal 130 extends into the second recess 112, and the other end passes through the fourth connection hole 114, and is used to connect a signal line.

[0037] This embodiment features a high-current signal transmission connector. When the male connector 100 and the female connector 200 are connected, the first protrusion 211 inserts into the first recess 111, and the second protrusion 212 inserts into the second recess 112. This allows one end of the first electrical contact 220 to be inserted into the first insertion hole 221, and one end of the second signal terminal 230 to extend into the second insertion hole 221, thus achieving electrical connection and signal transmission between the male connector 100 and the female connector 200. Therefore, signal transmission and electrical transmission are integrated into one unit, making the overall structure more compact and easier to connect when applied in a device.

[0038] Furthermore, refer to Figure 3 and Figure 5 An annular groove is provided on the outer side of the first protrusion 211 and the second protrusion 212, and a waterproof ring 240 is provided in the annular groove. When the first protrusion 211 is inserted into the first cavity 111 and the second protrusion 212 is inserted into the second cavity 112, the waterproof ring 240 is sealed and fitted with the inside of the cavity, achieving a waterproof effect.

[0039] Furthermore, refer to Figure 6 and Figure 7 The second contactor 120 has a central hole 121 and multiple elastic grooves 122 at one end extending into the first recess 111, with an elastic arm 123 formed between two adjacent elastic grooves 122. When one end of the second contactor 120 is inserted into the first insertion hole 221, the elastic arm 123 elastically deforms and elastically supports itself within the first insertion hole 221, which not only facilitates the insertion of the second contactor 120 into the first insertion hole 221 but also increases the stability of the connection.

[0040] Furthermore, both the first connector 220 and the second connector 120 have wiring holes at their tail ends, with solder notches on one side of the wiring holes. After the conductive part of the wire extends into the corresponding wiring hole, it can be soldered at the solder notch. The solder can fill the solder notch, making the connection between the wire and the connector more secure.

[0041] Furthermore, refer to Figures 8 to 10 To ensure a more stable combination of the male connector 100 and the female connector 200, this embodiment features first latches 215 on both sides of the female connector 210 and second latches 115 on both sides of the male connector 110 that engage with the first latches 215. Specifically, after the male connector 100 and the female connector 200 are inserted, the first latches 215 and the second latches 115 engage and secure them, preventing the male connector 100 and the female connector 200 from loosening or falling off after insertion.

[0042] Furthermore, refer to Figures 8 to 10 The male connector 110 has elastic pressing plates 140 on both sides, with a second latch 115 located on the outer side of the elastic pressing plates 140. The female connector 210 has downwardly extending extension arms 250 on both sides, with a first latch 215 located on the inner side of the extension arms 250. When the male connector 100 and the female connector 200 are combined, the extension arms 250 are located on the outer side of the elastic pressing plates 140, causing the first latch 215 to engage with the second latch 115. During the engagement process, the elastic pressing plates 140 are compressed and deformed, thus facilitating engagement. Furthermore, when separating the male connector 100 and the female connector 200, the elastic pressing plates 140 can be pressed to disengage the first latch 215 from the second latch 115, thus separating the male connector 100 and the female connector 200.

[0043] Furthermore, refer to Figure 11 Harmony Figure 12 To facilitate the installation of the male connector 100 and the female connector 200 into the equipment, a first flange 216 is provided on the female connector 210, and a second flange 116 is provided on the male connector 110. The locking screw can then pass through the first flange 216 and the second flange 116 to lock into the mounting position of the equipment, thus fixing the male connector 100 and the female connector 200 in the mounting position.

[0044] Furthermore, referring to Figure 12 In one embodiment of the high-current connector for signal transmission, the extension arm 250 is located on the bottom side of the first flange 216 for easy installation.

[0045] Furthermore, refer to Figure 11 In a more preferred embodiment, the female connector 210 has a first flange 216, and the male connector 110 has a second flange 116. Specifically, after the male connector 100 and the female connector 200 are combined, the first flange 216 and the second flange 116 are fitted together. A locking screw can pass through the first flange 216 and the second flange 116 to connect to the mounting position.

[0046] Furthermore, refer to Figure 1 and Figure 2The high-current connector for signal transmission also includes a first protective cover 300 and a second protective cover 400. The first protective cover 300 engages with the bottom side of the female connector 210. The second protective cover 400 engages with the bottom of the male connector 110. 113 The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
