Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a male connector used in vehicles. Background Technology

[0002] Currently, to achieve mechanical fixation and electrical connection of external devices, multiple accessories, including mounting brackets and electrical connectors, are typically used. For example, to fix and connect a mobile phone in a car, a phone holder and charger are usually installed on the center console. However, most car phone holders use a clamping method to fix themselves to the center console and only provide the function of fixing a mobile phone or portable device. To charge the device, a cable must be connected from the charging port on the center console, and the charging cable wraps around the center console area, which can affect safe driving. Furthermore, the related electrical connectors have a complex structure, high manufacturing cost, and are not conducive to automated production.

[0003] Therefore, it is hoped that a new male connector can be proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a male connector that is simple to manufacture and reduces costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a male connector, comprising a columnar insulating body, several conductive terminals fixed on the insulating body, and a metal shell supporting the insulating body. The conductive terminals have axially extending sheet-like peripheral wall portions, and the peripheral wall portions of the several conductive terminals are evenly arranged circumferentially on the peripheral wall of the insulating body. The insulating body is integrally injection molded onto the conductive terminals and the metal shell. The insulating body has an annular main body and several protrusions extending rearward from the rear end face of the annular main body. The peripheral wall portions of the conductive terminals are at least partially fixed within the protrusions and extend rearward beyond the rear end face of the protrusions. The metal shell has a circular base and several through slots penetrating the base axially. The annular main body abuts against the front end face of the base, and the protrusions fill the corresponding through slots.

[0006] In a preferred embodiment, the peripheral wall portion of the conductive terminal is provided with a retaining portion embedded in the insulating body and a peripheral wall contact portion exposed on the peripheral wall of the annular body, the peripheral wall contact portion extending forward from the retaining portion.

[0007] In a preferred embodiment, the annular body has a front portion that exposes the peripheral wall contact portion and a rear portion that covers part of the retaining portion, wherein the diameter of the rear portion is larger than the diameter of the front portion.

[0008] In a preferred embodiment, the peripheral wall portion of the conductive terminal has an extension portion extending rearward from the retaining portion to the rear end face of the protrusion portion, and the conductive terminal has a welding leg bent outward from the axial rear end of the extension portion.

[0009] In a preferred embodiment, the rear end face of the protrusion of the insulating body is flush with the rear end face of the base of the metal casing.

[0010] In a preferred embodiment, several of the conductive terminals are punched from the same terminal strip, and the outer portions of two adjacent conductive terminals in the terminal strip are connected in the circumferential direction by a strip.

[0011] In a preferred embodiment, the conductive terminal has an end wall portion that bends inward from the front end of the peripheral wall contact portion, and the end wall portions of several conductive terminals are evenly arranged in the circumferential direction on the front end surface of the annular body.

[0012] In a preferred embodiment, the metal outer shell has a threaded post extending axially forward from the center of the base, and the annular body of the insulating body is sleeved on the threaded post.

[0013] In a preferred embodiment, the conductive terminal has an embedded portion that bends radially inward from the end wall and extends into the annular body, the embedded portion being spaced apart from the threaded post portion.

[0014] In a preferred embodiment, the circumferential wall portion of the conductive terminal gradually decreases in length from front to back along the axial direction.

The insulating body has an annular main body and several protrusions extending rearward from the rear end face of the annular main body. The peripheral wall of the conductive terminal is at least partially fixed within the protrusions and extends rearward beyond the rear end face of the protrusions. The metal shell has a circular base and several through slots penetrating the base axially. The annular main body abuts against the front end face of the base, and the protrusions fill the corresponding through slots. The male connector can simultaneously achieve mechanical and electrical connections to portable devices. Furthermore, the conductive terminals are uniformly arranged circumferentially, meaning the number of conductive terminals can be increased according to requirements, thereby achieving diversified conductive functions. Further, the male connector is formed by cutting terminal strips after integral injection molding of the insulating body, greatly optimizing the production process and improving the automated manufacturing of the male connector.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0023] Please see Figures 1 to 6 As shown, a preferred embodiment of the present invention discloses a male connector 100 for mechanically and electrically connecting a portable device to an automobile. In this embodiment, the male connector 100 is embedded in a bracket module to provide holding and charging functions for the portable device.

[0024] Please see Figures 1 to 4 As shown, the male connector 100 includes a cylindrical insulating body 10, a plurality of conductive terminals 20 fixed on the insulating body 10, and a metal housing 30 supporting the insulating body 10. The metal housing 30 has a circular base 31 and a threaded post portion 32 extending axially forward from the center of the base 31. The threaded post portion 32 has external threads; therefore, the male connector 100 can be rotatably inserted into the corresponding female connector through the threaded post portion 32.

[0025] The insulating body 10 is integrally injection molded onto the conductive terminal 20 and the metal shell 30, greatly optimizing the manufacturing process of the male connector 100. Specifically, the insulating body 10 has an annular body 11 and several protrusions 12 extending rearward from the rear end face of the annular body 11; the annular body 11 is sleeved on the threaded post portion 32 and abuts against the front end face of the base 31. The metal shell 30 also has several through slots 311 penetrating the base 31 axially, and the protrusions 12 fill the corresponding through slots 311 to fix the insulating body 10 onto the metal shell 30.

[0026] The conductive terminal 20 has an axially extending sheet-like peripheral wall portion 21 and an end wall portion 22 that bends inward from the front end of the peripheral wall portion 21. The peripheral wall portions 21 of several conductive terminals 20 are evenly arranged circumferentially on the peripheral wall of the insulating body 10; therefore, in this case, adding more conductive terminals 20 circumferentially as needed will not increase the axial length of the male connector 100. Furthermore, the circumferential length of the peripheral wall portion 21 gradually decreases from front to back along the axial direction, ensuring sufficient contact area at the front end of the conductive terminals 20 while preventing short circuits between the rear end areas of the conductive terminals 20.

[0027] In this embodiment, the peripheral wall portion 21 of the conductive terminal 20 is at least partially fixed within the protrusion 12 and extends rearward beyond the rear end face of the protrusion 12. Specifically, the peripheral wall portion 21 has a holding portion 211 embedded in the insulating body 10, a peripheral wall contact portion 212 exposed on the peripheral wall of the annular body 11, and an extension portion 213 extending rearward from the holding portion 211 beyond the rear end face of the protrusion 12. The peripheral wall contact portion 212 extends forward from the holding portion 211. The annular body 11 has a front body portion 111 that exposes the peripheral wall contact portion 212 and a rear body portion 112 that covers part of the holding portion 211. The diameter of the rear body portion 112 is larger than the diameter of the front body portion 111, so that the peripheral wall contact portion 212 can be exposed on the peripheral wall of the front body portion 111 for mating with the female terminal of the female connector.

[0028] The retaining portion 211 is embedded within the rear portion 112 and the protruding portion 12 of the main body, and the extending portion 213 extends rearward from the retaining portion 211. The rear end face of the protruding portion 12 of the insulating body 10 is flush with the rear end face of the base 31 of the metal shell 30, that is, the extending portion 213 extends rearward beyond the rear end face of the base 31. Figure 5 and Figure 6 As shown, several conductive terminals 20 are punched from the same terminal strip 40. The outer extensions 213 of two adjacent conductive terminals 20 are connected circumferentially by a strip 41. Simultaneously, each conductive terminal 20 also has a welding leg 23 bent outwards from the axial rear end of the outer extension 213.

[0029] The end wall portion 22 is formed by bending inward from the front end of the peripheral wall contact portion 212 of the peripheral wall portion 21, and the end wall portions 22 of several conductive terminals 20 are evenly arranged circumferentially on the front end surface of the annular body 11. Since the end wall portion 22 of the conductive terminal 20 is an arc-shaped structure extending circumferentially, the female terminal of the female connector has a long contact area on the end wall portion 22. At the same time, the conductive terminal 20 is also provided with an embedded portion 221 that bends inward from the radial side of the end wall portion 22 and extends into the annular body 11 to increase the connection strength between the conductive terminal 20 and the insulating body 10; the embedded portion 221 is spaced apart from the threaded post portion 32 to avoid short circuits between them.

[0030] In this invention, the terminal strip 40 and the metal shell 30 are placed in an injection mold, and molten plastic is then injected onto the terminal strip 40 and the metal shell 30 to form the insulating body 10. Finally, the strip 41 of the terminal strip 40 is cut to form the aforementioned male connector 100. The male connector 100 can simultaneously achieve mechanical and electrical connections to portable devices. Furthermore, the conductive terminals 20 are evenly arranged circumferentially, meaning the number of conductive terminals 20 in the male connector 100 can be increased as needed to diversify conductive functions. Moreover, the male connector 100 is formed by cutting the terminal strip 40 after integral injection molding of the insulating body 10, greatly optimizing the production process and improving the automated manufacturing capability of the male connector 100.

[0031] In summary, the above are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model should still fall within the scope of the present utility model patent.
