Abstract
Description
[Technical Field] This utility model relates to the field of connector technology, and in particular to a connector internal positioning FAKRA adapter. [Background Technology] Existing FAKRA adapters typically use a testing method that positions the object under test based on its outer contour, guiding the object through a positioning opening on the adapter's perimeter. However, when the object under test has a large deviation and space is limited, the compatibility of such devices cannot achieve effective positioning, leading to damage to the object under test and thus failing to meet the requirements. [Utility Model Content] To overcome the above problems, this utility model proposes a connector internal positioning FAKRA adapter that can effectively solve the above problems.
[0004] The present invention provides a technical solution to solve the above-mentioned technical problems by providing a connector internal positioning FAKRA adapter, including a housing, on which an adapter body is connected; one end of the adapter body extends from the housing for connecting to an external connector, and the end of the adapter body extending from the housing is provided with a chamfer, the chamfer angle being 12°-18°; the housing is provided with a mounting groove, and the adapter body is tightly fitted into the mounting groove; a limiting hole is provided on the housing, the limiting hole communicating with the mounting groove, and a limiting pin is inserted into the limiting hole to fix the adapter body. Preferably, the outer side of the adapter body is provided with a limiting groove that matches the width of the limiting pin, and the limiting pin is inserted into the limiting groove.
[0005] Preferably, the adapter body includes an inner guide post, the limiting groove is disposed around the inner guide post, and the chamfer is disposed at one end of the inner guide post.
[0006] Preferably, a first accommodating space is provided inside the inner guide post, and a front isolation post and a rear isolation post are provided in the first accommodating space. One end of the front isolation post and the rear isolation post are tightly spliced together, and a second accommodating space is formed between the front isolation post and the rear isolation post. A signal post is provided in the second accommodating space.
[0007] Preferably, the signal post is secured within the second accommodating space, and the front isolation post and the rear isolation post are secured within the first accommodating space.
[0008] Preferably, the two ends of the signal post can be exposed from the two ends of the housing rather than protruding.
[0009] Preferably, a positioning groove is provided on the inner side of one end of the inner guide post, and an inner spring is connected in the positioning groove.
[0010] Preferably, the outer casing is provided with mounting holes, and a fixing hook is integrally formed on the outer casing.
[0011] Compared with existing technologies, the connector internal positioning FAKRA adapter of this utility model has greater compatibility when inserted into the test object through the large-angle chamfer at the front of the internal guide post. Compared with the external guidance method, the internal positioning method of this utility model greatly improves the test stability and avoids the situation of damage to the test object due to insufficient compatibility. In a certain sense, it reduces the cost of testing and improves economic efficiency.

Detailed Implementation Methods
[0014] It should be noted that in this embodiment of the invention, all directional indications (such as up, down, left, right, front, back, etc.) are limited to relative positions on the specified view, rather than absolute positions.
[0015] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0016] Please see Figures 1 to 5 The connector internal positioning FAKRA adapter of this utility model includes a housing 10, on which an adapter body 20 is connected. The adapter body 20 is a FAKRA adapter, and the number of them can be one, two or more.
[0017] One end of the adapter body 20 extends from the outer shell 10 for connecting to an external connector. The end of the adapter body 20 extending from the outer shell 10 is provided with a chamfer α, the angle of which is 12°-18°, preferably 15°.
[0018] When the connector internal positioning Fakra adapter of this utility model is connected to an external connector, the large-angle chamfer at the front of the adapter body 20 achieves greater compatibility within the available space. Compared with the external guiding method, the internal positioning method of this utility model greatly improves the test stability and avoids damage to the tested object due to insufficient compatibility. In a certain sense, it reduces the cost of testing and improves economic efficiency.
[0019] The outer casing 10 is provided with a mounting groove 11, and the adapter body 20 is tightly connected to the mounting groove 11.
[0020] A limiting hole 12 is provided on the outer shell 10. The limiting hole 12 is connected to the mounting groove 11. A limiting pin 30 is inserted into the limiting hole 12 to fix the adapter body 20, further preventing the adapter body 20 from coming out of the mounting groove 11 and improving the connection stability and reliability.
[0021] The outer side of the adapter body 20 is provided with a limiting groove 22 that matches the width of the limiting pin 30, and the limiting pin 30 is inserted into the limiting groove 22.

[0023] The outer casing 10 has an integrally formed fixing hook 14, which is used to fix the wire harness connector.
[0024] The adapter body 20 includes an inner guide post 40, a limiting groove 22 is disposed around the inner guide post 40, and a chamfer a is disposed at one end of the inner guide post 40.
[0025] The inner guide post 40 is provided with a first accommodating space, and a front isolation post 60 and a rear isolation post 80 are provided in the first accommodating space. One end of the front isolation post 60 and the rear isolation post 80 are tightly spliced together, and a second accommodating space is formed between the front isolation post 60 and the rear isolation post 80. A signal post 70 is provided in the second accommodating space.
[0026] The signal post 70 is secured within the second accommodating space, and the front isolation post 60 and the rear isolation post 80 are secured within the first accommodating space.
[0027] The two ends of the signal post 70 can be exposed from the two ends of the housing 10 instead of protruding, for connecting external cables.
[0028] A positioning groove is provided on the inner side of one end of the inner guide post 40, and an inner spring 50 is connected in the positioning groove.
[0029] During assembly, first press the rear isolating post 80 into the first receiving space of the inner guide post 40, then place the signal post 70 in the rear isolating post 80, then press the front isolating post 60 into the front of the inner guide post 40, then install the inner spring 50 into the positioning groove at the front end of the inner guide post 40, and finally press the assembled adapter body 20 into the housing 10.
