[0001] This invention relates to the field of electronic control units for vehicles, and more particularly to a male connector, an electrical connector unit, and an electronic control system. Background Technology

[0002] As is well known, electrical connector units used in vehicle electronic control systems typically include a male connector, which comprises a male connector body and a male shield that is inserted therein. For example... Figure 1 and Figure 2 As shown, in the prior art, when the male shield 100 is inserted into the male connector body 101, the male shield groove 1001 on the male shield 100 is assembled onto the protruding rib 1011 on the male connector body 101, and teeth 1002 are provided on the surface of the male shield groove 1001. The teeth 1002 are engaged with the protruding rib 1011 to ensure that the male shield 100 and the male connector body 101 can be fixedly connected. When assembling the male shield and the male connector body, a jig is required to apply force to the male shield to insert it into the male connector body. The above structure and installation method result in a large force being applied to the male shield when assembling the male connector with the jig, which increases the requirements for the installation jig.

[0003] Therefore, there is an urgent need for a male connector, electrical connector unit, and electronic control system to solve the problems mentioned above. Summary of the Invention

[0034] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. 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 invention based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment provides a male connector. Currently, when assembling a male connector, a jig is required to apply force to the shield to insert it into the male connector body. The existing structure and assembly method result in a large force being applied to the shield when assembling the male connector with the jig, which increases the requirements for the assembly jig and reduces assembly efficiency.

[0039] To address the aforementioned issues, this embodiment provides a male connector to reduce the requirements for assembly fixtures and improve assembly efficiency. For example... Figure 3 and Figure 4 As shown, the male connector includes a shield 1 and a connector body 2. The shield 1 includes a first end 10, which is inserted into the connector body 2.

[0040] Specifically, such as Figures 3-5 As shown, a receiving portion 12 is provided on the side wall of the shield 1 near the first end 10, and a protrusion 21 is provided on the connector body 2, which is snapped into the receiving portion 12. The shield 1 and the connector body 2 are fixed and limited by the snapping of the protrusion 21 and the receiving portion 12, which reduces the force required to be applied to the shield 1 during the insertion of the shield 1 into the connector body 2, reduces the requirements for assembly fixtures, improves assembly efficiency, and reduces costs.

[0041] In this embodiment, the receiving part 12 is a through hole opened on the side wall of the shield 1, and the protrusion 21 is a protrusion block provided on the connector body 2, which can be engaged in the through hole.

[0042] In other embodiments, the structure of the receiving portion 12 and the protrusion 21 is not limited to this, and is not limited here.

[0043] Specifically, multiple receiving portions 12 are provided, and the multiple receiving portions 12 are arranged circumferentially and at intervals along the shield 1, so that the shield 1 is more stably fixed and limited.

[0044] Preferably, such as Figure 4 As shown, the shielding body 1 includes multiple connecting surfaces 11 connected end to end, forming a shielding body 1 with a closed cross-section. The connecting surfaces 11 include alternating first surfaces 111 and second surfaces 112. The first surface 111 is provided with a receiving portion 12, and a contact arm 14 is connected to the end face of the first end 10 of the first surface 111. The spaced-apart receiving portions 12 ensure stable fixing and positioning of the shielding body 1, while also reducing the number of receiving portions 12 that need to be processed, thus improving production efficiency.

[0045] In this embodiment, the shield 1 is formed by bending a metal plate. The bent shield 1 has 16 connecting surfaces 11, each with the same length and width. The two ends of the metal plate overlap to form an overlap portion 1121. The cross-section of the shield 1 in this embodiment is a regular 16-sided polygon. Compared with a circular cross-section, a regular polygon is easier to bend in production, reducing the production difficulty of the shield 1 and saving time and costs.

[0046] In other embodiments, the cross-section of the shield 1 may also be a circular ring or other regular polygon with an even number of sides, which is not limited here.

[0047] Specifically, such as Figure 4 As shown, the second surface 112 includes the aforementioned overlapping portion 1121 and the second connecting surface 1122. A groove 13 is provided on the second connecting surface 1122, and one end of the groove 13 is connected to the end face of the first end 10. The groove 13 increases the deformation space of the shield 1 during assembly, reduces the assembly force required when the shield 1 is inserted into the connector body 2, reduces the requirements for assembly fixtures, and improves assembly efficiency.

[0048] Preferably, such as Figures 5-10As shown, the connector body 2 is used to insert the shield 1. The connector body 2 includes a mounting plate 23. The mounting plate 23 has an insertion groove 25. The bottom of the insertion groove 25 has a contact arm through hole 22 along the circumferential direction. The first end 10 of the shield 1 is inserted into the insertion groove 25, and the end of the first end 10 abuts against the bottom of the insertion groove 25. The contact arm 14 of the shield 1 passes through the contact arm through hole 22. The insertion groove 25 restricts the assembly depth of the shield 1 in the connector body 2, improves the stability of the shield 1 in the connector body 2 in terms of fixation and positioning, and enables the shield 1 to be positioned in time during assembly, thereby improving the assembly convenience of the male connector.

[0049] Preferably, such as Figures 9-10 As shown, the insertion slot 25 is provided with a main body inner ring 24 protruding from the mounting plate 23. The side wall of the main body inner ring 24 is provided with a protrusion 21 along the circumferential direction, so that the protrusion 21 is positioned corresponding to the receiving part 12, which facilitates assembly.

[0050] This embodiment also provides an electrical connector unit, including a male connector and a female connector as mentioned above, wherein the male connector is inserted into the female connector.

[0051] Specifically, the female connector includes a female shield, and the end of the male connector's shield 1 opposite to the first end 10 is inserted into the female shield. The female shield includes spring contacts, and the number of spring contacts is the same as the number of connecting surfaces 11 of the shield 1 and they are arranged accordingly. The spring contacts contact the connecting surfaces 11, increasing the number of contact points between the male connector's shield 1 and the female shield, improving the shielding effect of the electrical connector unit against external electromagnetic interference, and enhancing the shielding performance.

[0052] This embodiment also provides an electronic control system, including the electrical connector unit mentioned above, which improves the shielding effect against electromagnetic interference.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
