As shown in fig. 1 and 2, an electrical connector includes an insulating housing 1, a conductive plug 2, and a conductive circuit 3; the conductive circuit 3 is molded in the insulating shell 1, the conductive plug 2 is electrically connected with the conductive circuit 3, and the conductive plug 2 is exposed out of the insulating shell 1; an external terminal 31 is formed on the conductive circuit 3, the external terminal 31 is at least partially exposed out of the insulating shell 1, and an insulating sealing device (not shown in the figure, and can be sealed by sealant in specific use) is arranged on the external terminal 31; the conductive plug 2 is made of a first conductive material and the conductive circuit 3 is made of a second conductive material.

In the specific use process, the electric connector can be electrically connected with external equipment through the conductive plug 2, one end of the conductive plug 2 is exposed outside the insulating shell 1, the other end of the conductive plug 2 is connected with the conductive circuit 3, and the conductive plug 2 can transmit external electric signals to the conductive circuit 2; in addition, the external terminal 31 is at least partially exposed outside the insulating housing 1, so that the conductive circuit 3 can be electrically connected with another external electronic device through the external terminal 31; when in use, the part of the external terminal 31 exposed out of the insulating shell 1 can be sealed by the insulating sealing device, so that the external terminal is sealed in the insulating sealing device, and the rust phenomenon is avoided; for example, when the exposed portion of the external terminal 31 is connected to other electronic components (such as a switch, a resistor, etc.), plastic-coating sealing is performed, or the exposed portion of the external terminal 31 is oiled or the like to prevent oxidation corrosion.

In this embodiment, since the electrical connector includes the insulating housing 1, the conductive plug 2 and the conductive circuit 3, the conductive circuit 3 can be molded in the insulating housing 1, so that the insulating housing 1 can protect the conductive circuit 3 from contacting the external environment, thereby avoiding corrosion and prolonging the service life; by electrically connecting the conductive plug 2 with the conductive circuit 3 and exposing at least part of the conductive plug 2 outside the insulating housing 1, the conductive plug 2 is exposed to the use environment when in use, and the conductive circuit 3 is sealed inside the insulating housing 1; the conductive plug 2 is made of a first conductive material, the conductive circuit 3 is made of a second conductive material, so that the conductive plug 2 and the conductive circuit 3 are made of different conductive materials, and the conductive plug 2 and the conductive circuit 3 are made of the first conductive material and the second conductive material with different performances according to different use environments; so that, in use, only the corrosion protection design requirement of the conductive plug 2 is considered, but not the corrosion protection design requirement of the conductive circuit 3 is not considered, for example, the conductive plug 2 is made of a material with better corrosion resistance (relatively more expensive), and the conductive circuit 3 is made of a material with relatively poorer corrosion resistance (relatively cheaper), so that the production cost is reduced on the premise of ensuring the conductivity or the signal transmission requirement.

The embodiment changes the traditional electric connector setting, and the conductive plug and the conductive circuit are made of different materials, so that more choices are provided for reducing the production cost. Because the conductive circuit is in the insulating shell in a plastic package mode, the conductive circuit can be prevented from being oxidized and rusted by contacting air or water, so that the conductive circuit does not need to be made of an oxidation-resistant material, and oxidation-resistant treatment is not needed, and the production cost is reduced.

As a preferred embodiment, the first conductive material is a copper material and the second conductive material is an iron material. The conductive plug 2 is made of a copper material having good conductivity, such as brass. The conductive circuit 3 is made of iron, the iron is relatively cheaper than copper, and the copper and the iron are matched for use, so that the conductive requirement can be met, and the large-scale production cost can be reduced. Of course, other oxidation-resistant conductive materials, such as silver, may be used as the first conductive material; other cheaper conductive materials, such as aluminum, can also be used for the second conductive material.

The insulating housing 1 is made of a high polymer, and in order to improve the high/low temperature resistance and flame retardance of the electric connector, the geometric structure of the internal conductive circuit 3 is ensured to be stable and reliable, and as a preferred embodiment, the insulating housing 1 is made of engineering plastics and molded by thermosetting plastics, and the engineering plastics has good insulativity, low thermal conductivity and stable chemical property and cannot be corroded. The insulating housing 1 tightly encapsulates the conductive circuit 3, prevents the internal conductive circuit 3 from being oxidized and rusted by air or water, has certain strength, and can avoid the deformation of the internal conductive circuit 3.

As shown in fig. 3, the conductive plug 2 and the conductive circuit 3 are welded to each other, the welding structure is light in weight and low in cost, the production cost is saved while the stability of the connecting structure is satisfied, and in this embodiment, the welding mode can be laser welding or resistance welding. Of course, the conductive plug 2 and the conductive circuit 3 can be connected with each other by quick-inserting riveting, and the riveting structure is vibration-resistant and impact-resistant, so that the connection between the conductive plug 2 and the conductive circuit 3 is firm and reliable. The production requirement can be met through the mode of the fixed connection, and the connection stability of the conductive plug 2 and the conductive circuit 3 is improved.

As shown in fig. 1, the number of the conductive plugs 2 is two or more, each conductive plug 2 is electrically connected to the conductive circuit 3, and the conductive plugs 2 are disposed at intervals. In this embodiment, by providing a plurality of conductive plugs 2, a plurality of transmission channels are provided, and the practicality of the electrical connector is improved.

As shown in fig. 1, in this embodiment, the conductive plugs 2 are uniformly distributed along the same straight line, and of course, in actual production, the conductive plugs 2 may be uniformly divided into a plurality of groups for arrangement according to the specific number of the conductive plugs 2. The insulating housing 1 is formed with a recess 12, and the conductive plug 2 is located in the recess 12. The insulating housing 1 is formed with a mounting hole 11, and the conductive plug 2 is electrically connected to the conductive circuit 3 through the mounting hole 11. In this embodiment, the groove 12 and each conductive plug 2 together form a male head of the electrical connector, specifically, as shown in fig. 1 and 2, a groove 12 is formed on the insulating housing 1 at one end of the electrical connector, a mounting hole 11 is formed at the bottom end of the groove 12, a plurality of conductive plugs 2 are arranged along the same line and are only inside the groove 12, and one end of each conductive plug 2 passes through the mounting hole 11 to be electrically connected with the conductive circuit 3 inside the insulating housing 1, and the connector female head of the external device is mutually plugged with the male head of the electrical connector for electrical signal transmission.

As shown in fig. 2, the mounting hole 11 is provided with a sealing structure 4, and the sealing structure 4 is used for sealing a gap between the mounting hole 11 and the conductive plug 2. In this embodiment, the sealing structure 4 is formed by molding silicone rubber (may be formed by injection molding together with the insulating housing 1 during manufacturing), so as to prevent dust, air, water vapor, etc. from penetrating into the insulating housing 1, thereby playing a role in protecting the electrical connector, and of course, the sealing treatment of the mounting hole 11 may also be performed by using a rubber sealing ring, or a glue filling method may be used at the joint of the conductive plug 2 and the mounting hole 11, which is beneficial to miniaturization and light weight of the device.

As shown in fig. 4, the conductive circuit 3 has a three-dimensional wiring structure, that is, the conductive circuit 3 is arranged in a plurality of planes in a meandering manner. In the present embodiment, the conductive circuit 3 is spatially wired according to the installation environment in consideration of the fact that the installation environment of the electrical connector may be crowded or irregular, so that the electrical connector is convenient to install or place. Meanwhile, the conductive circuits 3 are arranged in a plurality of planes in a zigzag manner, so that the whole electric connector can be well embedded into an installation environment, the electric connector is not easy to be impacted to deform, and the whole stability of the electric connector is improved.

Accordingly, as shown in fig. 1, the insulating housing 1 is molded according to the wiring structure of the conductive circuit 3 to form a plurality of planes, and since the insulating housing 1 is molded by thermosetting plastic in this embodiment, the weight is lighter, and the insulating housing can be tightly coated on the surface of the conductive circuit 3 to form protection, thereby achieving the purpose of plastic packaging the conductive circuit 3 and reducing the volume of the electrical connector.

Further, as shown in fig. 5, the conductive circuit 3 is formed with a plurality of external terminals 31, and one end of the external terminal 31 is perpendicular to the conductive circuit 3 body and is connected with the conductive circuit 3 body; the other end of the external terminal 31 extends out of the insulating shell 1 to be electrically connected with external equipment. The external terminal 31 is made of the same material as the conductive circuit 3, and may be made of iron or aluminum, etc., and in order to prevent the external terminal 31 from being corroded by the environment, an insulating sealing device may be disposed on the external terminal 31, for example, insulating sealing is performed by using insulating glue or coating protection is performed on the surface, that is, after the external terminal 31 is electrically connected with a wire of an external device, insulating sealing is performed on the joint (including the external terminal 31) by using insulating glue.

In this embodiment, the electrical connector is not limited to performing single electrical signal transmission, and the electrical connector can collect or distribute multiple electrical signals through a general plug-in male connector (see embodiment one) and multiple external terminals, so as to improve the performance of the electrical connector; in addition, the external terminals are sealed, so that the external terminals are prevented from contacting the external environment, corrosion is avoided, and the effect of prolonging the service life is achieved.
