Abstract
Description
Technical Field
[0001] This application generally relates to the field of electrical equipment, and more specifically to a connector, particularly a connector for vehicles, such as a FAKRA connector, a Mini-FAKRA connector, an HFM connector, and so on. Background Technology
[0002] In existing connectors (e.g., RF connectors), the first housing (e.g., a metal housing) and the outer conductor are typically fixed to the second housing (e.g., a plastic housing) by riveting. This arrangement results in a complex structure, cumbersome assembly process, and high manufacturing costs. Furthermore, the bosses and clips of the first housing are usually riveted to the ribs of the second housing, which can lead to insufficient holding force and easy detachment after high-temperature aging. Utility Model Content
[0003] To overcome the aforementioned deficiencies in the prior art, this application provides a connector comprising a first housing and a second housing that can be assembled together. The first housing includes a first housing body and a columnar outer conductor extending from the front flat surface of the first housing body. The second housing includes a second housing body, which includes a through hole disposed on the rear flat surface of the second housing body. When the first and second housings are assembled together, the columnar outer conductor extends through the through hole into the interior of the second housing body. The first housing also includes at least one recess formed recessed on the outer peripheral surface of the columnar outer conductor, and the second housing also includes at least one resilient snap formed at the periphery of the through hole. The resilient snap extends obliquely radially inward inside the second housing body. When the first and second housings are assembled together, the resilient snap engages in the corresponding recess, and the front flat surface of the first housing body and the rear flat surface of the second housing body are in contact with each other. Accordingly, the retaining force between the first and second housings can be improved, and the first housing can be prevented from retracting and falling off after assembly.
[0004] Furthermore, the first housing includes a plurality of recesses, which are equally spaced along the circumferential direction on the outer peripheral surface of the columnar outer conductor. Accordingly, the second housing can be connected to the first housing at different rotation angles relative to the first housing, thereby improving adaptability.
[0005] Furthermore, the second housing includes a plurality of elastic clips, which are arranged at equal intervals along the circumferential direction at the periphery of the through hole, and the number of elastic clips is equal to the number of recesses. This further improves the connection strength between the first and second housings.
[0006] Furthermore, the second housing also includes at least one protrusion formed at the periphery of the through hole, which abuts against the outer peripheral surface of the columnar outer conductor when the first housing and the second housing are assembled together. This prevents wobbling between the second housing and the first housing during use.
[0007] Furthermore, the second housing also includes a plurality of protrusions formed at the periphery of the through hole, each protrusion being disposed circumferentially between two adjacent elastic clips. When the first housing and the second housing are assembled together, the protrusions abut against the outer peripheral surface of the columnar outer conductor. This prevents the second housing from wobbling around the first housing during use.
[0008] Furthermore, the first housing also includes at least one limiting block extending from the front flat surface of the first housing body, the extending direction of the limiting block being parallel to the extending direction of the columnar outer conductor; and the second housing also includes at least one recess formed recessed from the rear flat surface of the second housing body, the number of limiting blocks being equal to the number of recesses, wherein when the first housing and the second housing are assembled together, the limiting blocks are inserted into the corresponding recesses. Accordingly, the connection strength between the first housing and the second housing can be further improved.
[0009] Furthermore, the second housing includes a plurality of grooves, which are arranged at equal intervals in the circumferential direction around the through-hole. This allows for a balanced increase in retaining force.
[0010] Furthermore, with the first and second housings assembled together, the limiting block is interference-fitted into the corresponding groove. This improves positioning accuracy and prevents wobbling between the second and first housings after assembly.
[0011] Furthermore, when the first and second housings are assembled together, a gap is formed between the top of the limiting block and the bottom surface of the groove. This prevents misalignment during assembly.
[0012] Furthermore, the first housing includes a plurality of the aforementioned columnar outer conductors, and the second housing body includes a plurality of the aforementioned through holes, wherein the number of the columnar outer conductors is the same as the number of the through holes. Accordingly, the connector of this application has stronger adaptability. Attached Figure Description

Regarding the drawings, directional terms such as “top,” “bottom,” “inner,” “outer,” “upper,” “lower,” “front,” and “rear” are used with reference to the orientation of the drawings described. Since components of the embodiments of this application can be positioned in many different orientations, directional terms are for illustrative purposes only and are not intended to be limiting. It should be understood that other embodiments may be used, and structural or logical changes may be made without departing from the scope of this application. Therefore, the following detailed description should not be construed as limiting, and the present application is defined by the appended claims.
[0037] refer to Figures 1 to 3 This application provides a connector 100, such as a radio frequency connector. The connector 100 includes a first housing 1 and a second housing 2 that can be assembled together. The first housing 1 may be, for example, a zinc alloy housing, while the second housing 2 may be, for example, a plastic housing. Figure 1 and Figure 2 The connector 100 is shown in both its disassembled and assembled states.
[0038] The first housing 1 includes a first housing body 11 and a cylindrical outer conductor 12 extending from the front flat surface S1 of the first housing body 11. The cylindrical outer conductor 12 may have a cylindrical shape. Of course, this application is not limited to this; for example, the cylindrical outer conductor 12 may also have a prism shape, such as a square prism shape, etc.
[0039] The second housing 2 includes a second housing body 21, and the second housing body 21 includes a through hole H disposed on the rear flat surface S2 of the second housing body 21. When the first housing 1 and the second housing 2 are assembled together, the columnar outer conductor 12 extends through the through hole H into the interior of the second housing body 21. The through hole H may have a circular shape. However, this application is not limited to this; for example, the through hole H may also have a square shape or other polygonal shapes.
[0040] The first housing 1 may further include at least one recess 13 recessed into the outer peripheral surface of the columnar outer conductor 12, and the second housing 2 may further include at least one elastic snap 22 formed at the periphery of the through hole H, the elastic snap 22 extending radially inward at an angle inside the second housing body 21. When the first housing 1 and the second housing 2 are assembled together, the elastic snap 22 engages in the corresponding recess 13, and the front flat surface S1 of the first housing body 11 and the rear flat surface S2 of the second housing body 21 contact each other. Furthermore, the front end (i.e., the free end) of the elastic snap 22 abuts against one side of the bottom of the corresponding recess 13, and the end of the elastic snap 22 abuts against the front flat surface S1 of the first housing body 11. Accordingly, the retaining force between the first housing 1 and the second housing 2 can be improved, and the first housing 1 can be prevented from retracting and falling off after assembly.
[0041] In one embodiment, the first housing 1 may include a plurality of recesses 13, which are equally spaced along the circumferential direction on the outer peripheral surface of the columnar outer conductor 12. In this case, the resilient snap 22 of the second housing 2 can be engaged in any of the recesses 13, so that the first housing 1 and the second housing 2 can be connected to each other at a desired rotation angle as needed.
[0042] In another embodiment, the second housing 2 may include a plurality of resilient latches 22, which are arranged at equal intervals along the circumferential direction at the periphery of the through hole H, and the number of resilient latches 22 is equal to the number of recesses 13. In other words, the plurality of recesses 13 and the plurality of resilient latches 22 engage in a one-to-one correspondence.
[0043] Furthermore, the second housing 2 may also include at least one protrusion 23 formed at the periphery of the through hole H, and the protrusion 23 extends radially toward the central axis of the through hole H inside the second housing body 21. When the first housing 1 and the second housing 2 are assembled together, the protrusion 23 may abut against the outer peripheral surface of the columnar outer conductor 12.
[0044] In one embodiment, the second housing 2 may include a single protrusion, such as a single partially annular protrusion. This arrangement is particularly suitable when the first housing 1 has a single recess 13 and the second housing 2 has a single resilient snap 22.
[0045] In another embodiment, the second housing 2 may further include a plurality of protrusions 23 formed at the periphery of the through hole H, each protrusion 23 being disposed in the circumferential direction between two adjacent elastic snaps 22. When the first housing 1 and the second housing 2 are assembled together, the protrusions 23 abut against the outer peripheral surface of the columnar outer conductor 12, particularly at the portion of the outer peripheral surface of the columnar outer conductor 12 located between two adjacent elastic snaps 22.
[0046] Furthermore, the first housing 1 may also include at least one limiting block 14 extending from the front flat surface S1 of the first housing body 11, the extending direction of the limiting block 14 being parallel to the extending direction of the columnar outer conductor 12. It should be noted that the extending direction of the columnar outer conductor 12 is also parallel to the assembly direction of the first housing 1 and the second housing 2. The second housing 2 may also include at least one groove 24 recessed from the rear flat surface S2 of the second housing body 21, the number of limiting blocks 14 being equal to the number of grooves 24. When the first housing 1 and the second housing 2 are assembled together, the limiting blocks 14 are inserted into the corresponding grooves 24. Specifically, a groove 24 may correspond to a protrusion 23, and the bottom surface of each groove 24 may be coplanar with a side surface of the corresponding protrusion 23 in a direction parallel to the central axis of the through hole H; or alternatively, a groove 24 may correspond to an elastic snap 22, and the bottom surface of each groove 24 may be coplanar with the end of the corresponding elastic snap 22.
[0047] In one embodiment, the second housing 2 may include a plurality of recesses 24 (in Figure 6 (As shown in the figure, four) Multiple grooves 24 are arranged at equal intervals in the circumferential direction around the through hole H. In other words, these grooves 24 are uniformly arranged around the through hole H.
[0048] In another embodiment, with the first outer shell 1 and the second outer shell 2 assembled together, the limiting block 14 can be interference-fitted into the corresponding groove 24. Of course, this application is not limited to this; for example, there may be a certain gap or allowance between the limiting block 14 and the edge of the groove.
[0049] In another embodiment, with the first housing 1 and the second housing 2 assembled together, a gap may be formed between the top of the limiting block 14 and the bottom surface of the groove 24. In other words, after assembly, the top of the limiting block 14 does not contact the bottom surface of the groove 24.
[0050] In addition, besides, for example, in Figure 1 In addition to the case where the first housing 1 shown includes a single columnar outer conductor 12, the first housing 1 may also include multiple columnar outer conductors 12, such as two, four, etc., and the second housing body 21 includes multiple through holes H, wherein the number of columnar outer conductors 12 is the same as the number of through holes H. In other words, the multiple columnar outer conductors 12 and the multiple through holes H are arranged in a one-to-one correspondence.
[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
