[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] like Figure 1-8 As shown, an embodiment of the present invention provides a connector 2, which includes a housing and terminals disposed within the housing. The housing includes a base 21 and a retaining ring 22 formed on the end face of the base 21 facing the mating connector 1. The terminals are inserted into the base 21 and one end is received within the retaining ring 22. The end face of the base 21 facing the corresponding mating connector 1 is provided with a first protrusion 28 in the area located within the retaining ring 22. The end of the first protrusion 28 away from the base 21 is provided with a first reference surface 26, which is perpendicular to the insertion direction of the connector 2.

[0034] The first reference surface 26 can be used as a reference for the processing and assembly of the connector 2, such as a reference positioning during housing injection molding or quality inspection, or a reference positioning during terminal assembly. Moreover, the area of ​​the first reference surface 26 is relatively small and not easily deformed, making it more reliable for reference. Furthermore, the first protrusion 28 can reduce or prevent the deformation of the large plane on the base 21, providing a prerequisite for the high-precision processing and assembly of the connector 2.

[0035] Furthermore, considering the need to improve the reference effect, the first protrusion 28 is symmetrically distributed relative to the terminals, such as... Figure 5 As shown, in this embodiment, four first protrusions 28 are provided and symmetrically distributed. Each first protrusion 28 has a first reference surface 26 at the end away from the base 21, and each first reference surface 26 is located in the same plane.

[0036] Furthermore, in order to obtain more reference surfaces, a reference system is formed by combining the first reference surface 26, such as... Figure 2-6 As shown, in this embodiment, the terminal includes a conductor 23 and a core 24 that passes through the outside of the conductor 23. The end of the core 24 facing the corresponding mating connector 1 has a protective ring 25 surrounding the corresponding end of the terminal. There is a gap between the inner wall of the protective ring 25 and the conductor 23. A second protrusion 29 is provided on the inner wall of the protective ring 25. A second reference surface 27 is provided at the end of the second protrusion 29 facing the conductor 23. The second reference surface 27 is perpendicular to the first reference surface 26. In this embodiment, multiple second protrusions 29 are provided around the conductor 23 in each terminal to form multiple second reference surfaces 27.

[0037] Furthermore, in order to enable the second reference surface 27 to meet the mating requirements with the mating connector 1, in this embodiment, the second reference surface 27 extends from the end of the protective ring 25 near the corresponding mating connector 1 along the insertion direction to the end of the protective ring 25 away from the corresponding mating connector 1.

[0038] Considering ease of assembly and practicality, in this embodiment, the conductor 23 is connected to the core 24 by a snap-fit ​​structure 4, and the core 24 is connected to the base 21 by a bolt structure 3. The snap-fit ​​structure 4 and the bolt structure 3 are conventional technologies, so they will not be described in detail or shown further here.

[0039] like Figure 1-8 As shown, the embodiments of this utility model also relate to a connection component, including the aforementioned connector 2 and a mating connector 1 that is adapted to be inserted into the aforementioned connector 2. The mating connector 1 has an avoidance groove at one end facing the connector 2 to avoid the first protrusion 28.

[0040] Furthermore, in order to mate with the second reference plane 27 to satisfy the positioning reference, such as Figure 8As shown, the mating connector 1 has a mating terminal that is adapted to be inserted into the connector 2 at one end. The mating terminal includes a mating conductor 11 and a mating core 12 surrounding the outer periphery of the mating conductor 11. The outer periphery of the mating core 12 is provided with a third protrusion 13. The end of the third protrusion 13 facing away from the mating conductor 11 is provided with a third reference surface 14. The third reference surface 14 is perpendicular to the first reference surface 26.

[0041] Further, as described above for connector 2, the terminal includes a conductor 23 and a core 24 that passes through the outside of the conductor 23. The end of the core 24 facing the corresponding mating connector 1 is provided with a protective ring 25 surrounding the outside of the corresponding end of the terminal. There is a gap between the inner wall of the protective ring 25 and the conductor 23. The inner wall of the protective ring 25 is provided with a second protrusion 29. The end of the second protrusion 29 facing the conductor 23 is provided with a second reference surface 27.

[0042] When connector 2 is inserted into mating connector 1, the mating terminals are inserted into the gap, and the second reference surface 27 and the third reference surface 14 are in contact with each other and slide together, thereby achieving the purpose of reference positioning.

[0043] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
