Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a TYPE-C dual-contact male connector. Background Technology

[0002] Automotive TYPE-C board-end connectors play an important role in connecting automotive electronic devices. They are compact and multifunctional, capable of charging and transmitting power as well as being compatible with data transmission from various devices. They are widely used in connecting audio-visual equipment, storage devices, or other automotive devices.

[0003] However, existing automotive Type-C board connectors often employ a single-layer contact structure. While this structure can meet basic connection requirements under normal conditions, it is subject to continuous vibration during vehicle operation, especially on bumpy roads. This vibration significantly impacts the connection stability and reliability of single-layer contact automotive Type-C board connectors. The single-layer contact structure is prone to failure, leading to issues such as screen flickering or momentary disconnections. This can affect the normal operation of in-vehicle devices, potentially causing loss of driving image data or distracting the driver, thus posing a safety hazard.

[0004] Therefore, given the single-layer contact structure of existing automotive TYPE-C board-end connectors and its problems in vibration environments, further technical improvements are urgently needed to adapt to vibration environments and ensure the continuity of signal transmission and the normal operation of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a TYPE-C dual-contact male connector to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A TYPE-C dual-contact male connector includes a plastic body, a metal shell, and electrical connecting elements. The plastic body has upper and lower mounting slots for mounting the electrical connecting elements. The metal shell completely covers the outer surface of the plastic body. The electrical connecting elements include an upper row of terminal assemblies fixed in the upper mounting slot and a lower row of terminal assemblies fixed in the lower mounting slot. Each conductive terminal of the upper and lower row of terminal assemblies has two electrical contacts.

[0008] Furthermore, the upper terminal assembly includes a plurality of first conductive terminals and a first terminal fixing core for fixing the plurality of equidistantly arranged first conductive terminals using an insert injection molding process; the lower terminal assembly includes the same number of second conductive terminals as the first conductive terminals and a second terminal fixing core for fixing the plurality of equidistantly arranged second conductive terminals using an insert injection molding process.

[0009] Furthermore, the contact portions of both the first conductive terminal and the second conductive terminal include two opposing elastic contact arms.

[0010] Furthermore, both the lower part of the first terminal fixing core and the upper part of the second terminal fixing core are provided with openings to facilitate cutting the terminals off the strip.

[0011] Furthermore, both the first terminal fixing core and the second terminal fixing core are provided with barbs that engage with the fixing holes in the mounting groove.

[0012] Furthermore, a shielding partition is provided between the upper row terminal assembly and the lower row terminal assembly.

[0013] Furthermore, the end of the mounting groove used for insertion with the TYPE-C dual-contact female connector is formed with an insertion guide structure to improve insertion accuracy.

[0014] Furthermore, the metal outer shell is tightly fitted onto the plastic body.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] The TYPE-C dual-contact male connector provided by this utility model, by transforming a single-layer single-contact structure into a dual-layer dual-contact structure, compensates for the defects such as screen flickering or momentary disconnection that occur after a single contact fails when a single layer is plugged in, and significantly improves the stability and reliability of the connection.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] This utility model embodiment provides a TYPE-C dual-contact male connector, including a plastic body 1, a metal shell 2, and electrical connecting elements, specifically:

[0027] like Figures 1 to 4 As shown, in this embodiment, the plastic body 1 is integrally injection molded. The plastic body 1 has the shape of a TYPE-C plug and has two layers of mounting slots (i.e., upper mounting slot 101 and lower mounting slot 102) for mounting electrical components. The front end of the mounting slot (i.e., the end for insertion with the TYPE-C dual-contact female connector) is formed with a mating interface 103 for docking with the TYPE-C dual-contact female connector. The mating interface 103 adopts a tapered design, forming a mating guide structure inside to improve the insertion accuracy and guide the connector towards the electrical component during insertion. When the TYPE-C dual-contact male connector is mated with the TYPE-C dual-contact female connector, it can pass through the mating interface 103 and accurately connect to the electrical component inside the plastic body 1.

[0028] The metal shell 2 is tightly fitted onto the plastic body 1 with a certain interference fit, so that the metal shell 2 completely covers the outer surface of the plastic body 1. The tight connection is achieved by the friction and clamping force generated by the interference fit between the two, which improves the structural strength of the connector, protects the internal electrical components of the connector, and prevents external physical damage and electromagnetic interference.

[0029] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the connecting element includes an upper row of terminal assemblies fixed in the upper mounting groove 101 and a lower row of terminal assemblies fixed in the lower mounting groove 102. Each conductive terminal of the upper and lower row of terminal assemblies has two electrical contacts. The upper row of terminal assemblies includes a plurality of first conductive terminals 3 arranged at equal intervals and a first terminal fixing core 4 that fixes the plurality of first conductive terminals 3 using an insert injection molding process. Similarly, the lower row of terminal assemblies includes a plurality of second conductive terminals 5 in the same number as the first conductive terminals 3 and positioned corresponding to the first conductive terminals 3, and a second terminal fixing core 6 that fixes the plurality of second conductive terminals 5 using an insert injection molding process.

[0030] Furthermore, a shielding partition 7 is inserted in the groove between the upper mounting groove 101 and the lower mounting groove 102 of the plastic body 1. The shielding partition 7 is located between the upper row terminal assembly and the lower row terminal assembly to reflect and absorb external electromagnetic interference signals and prevent them from entering the connector and affecting the accuracy of data transmission.

[0031] To improve assembly efficiency, both the first terminal fixing core 4 and the second terminal fixing core 6 are provided with barbs 401 that engage with the fixing holes 104 in the mounting groove, allowing the terminal assembly to be quickly inserted into the mounting groove. Additionally, openings 402 are provided at the lower part of the first terminal fixing core 4 and the upper part of the second terminal fixing core 6, allowing the cut portions of the first conductive terminal 3 and the second conductive terminal 5 to be exposed outside the fixing core, facilitating the removal of the conductive terminals from the material strip after injection molding.

[0032] Both the first conductive terminal 3 and the second conductive terminal 5 are integrally stamped, and both adopt a double-contact design. Taking the above-mentioned terminal block assembly as an example... Figure 4 and Figure 5As shown, the first terminal fixing core 4 uses an insert injection molding process to fix several equidistantly arranged first conductive terminals 3, so as to accurately fix the position of the terminals and prevent the terminals from shifting during use, thereby ensuring the stability and reliability of the connection. The first conductive terminal 3 includes a terminal body 301, a contact part, and a welding part 303. The terminal body 301 is embedded in the first terminal fixing core 4; the contact part is located at the front end of the terminal body 301, specifically two opposing elastic contact arms 302, which can simultaneously contact the upper and lower contact surfaces of a single female terminal of the TYPE-C dual-contact female connector, realizing dual-contact electrical contact, thereby preventing screen flickering or momentary disconnection caused by single-contact failure when the vehicle is subjected to road bumps and vibrations during driving, ensuring the connection stability between the vehicle data cable and the vehicle equipment; the welding part 303 is located at the rear of the terminal body 301 and is used to weld to the PCB board to achieve mechanical fixation and electrical connection, ensuring the effective transmission of power and signals.

[0033] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
