Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, and in particular to a three-way connector for automobiles. Background Technology

[0002] Automotive internal piping connection technology is a crucial link in ensuring the normal operation of various vehicle systems. With the development of automotive lightweighting and modularization, higher requirements are placed on the integration, reliability, and ease of installation of piping connectors.

[0003] In existing technologies, tee fittings mostly adopt an integrated structure, with three connectors connecting to different pipelines in the vehicle, and are widely used in cooling, fuel, braking, and other circulation systems. However, these systems often carry certain impurities during operation, such as particulate matter, sediment, or gum residue. These impurities tend to accumulate gradually at the joints or inside the flow channels of the tee fitting, leading to a reduction in the flow cross-section and even causing blockages, seriously affecting the normal circulation and working efficiency of the system.

[0004] In view of the above-mentioned related technologies, in order to prevent blockage at the connection of the tee connector, the inventor believes that it is necessary to provide a tee connector for automobiles. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Example 1 This application discloses a three-way connector for automobiles. (Refer to...) Figure 1 An automotive T-connector includes a mounting base 1 and a T-shaped connector integrally mounted on the mounting base 1. The T-connector has three connectors 2 and is T-shaped. Each connector 2 has a removable filter assembly inside its cavity. The filter assembly filters impurities in the fluid, preventing impurities from accumulating and clogging at the connection point of the connector 2. The removable design facilitates cleaning or replacement of the filter assembly.

[0034] Reference Figure 2 The filter assembly includes a filter seat 3 adapted to the inner diameter of the connector 2 and a locking structure for locking the filter seat 3 within the connector 2. At least two sliding portions 31 are provided circumferentially along the outer wall of the filter seat 3. A guide groove 21 is provided on the inner wall of the connector 2 to slide and engage with the sliding portions 31. Through the engagement of the sliding portions 31 and the guide groove 21, the filter seat 3 can be accurately and smoothly installed into the connector 2. In the embodiment of the application, there are two sets of sliding portions 31, which are circumferentially arranged on the outer wall of the filter seat 3.

[0035] Reference Figure 2The filter base 3 includes a filter frame 32 and a filter element 33 that can be detachably installed on the filter frame 32. The filter element 33 has a plurality of filter holes 331.

[0036] Reference Figure 3 The filter element 33 is symmetrically provided with locking protrusions 332 on its outer periphery, and the filter frame 32 is provided with locking grooves 321 for the locking protrusions 332 to be inserted into; the end face of the locking protrusions 332 is provided with locking holes 3321, and a second ball spring plunger 33211 is installed in the locking holes 3321; the inner wall of the locking groove 321 is provided with a second snap-fit ​​groove 32111 for the plunger balls of the second ball spring plunger 33211 to be snapped into.

[0037] Reference Figure 3 The locking groove 321 includes a first groove 3211 arranged circumferentially and a second groove 3212 connected to the first groove 3211 and arranged axially, wherein the second engaging groove 32111 is located on the inner sidewall of the first groove 3211. During installation, the locking protrusion 332 is first inserted axially along the second groove 3212, and then the filter element 33 is rotated so that the locking protrusion 332 enters the first groove 3211. At this time, the ball of the second ball spring plunger is precisely engaged in the second engaging groove 32111.

[0038] Reference Figure 2 The locking structure includes a first ball spring plunger 3111 disposed on the outside of the sliding part 31 and a first engaging groove 211 opened on the inner wall of the guide groove 21 for the first ball spring plunger 3111 plunger ball to engage. A plunger hole 311 for the first ball spring plunger 3111 to be installed is opened on the outside of the sliding part 31.

[0039] Reference Figure 2 The inner side of the inlet end of the connector 2 is provided with an annular limiting boss 22 for axial positioning of the filter assembly. The annular limiting boss 22 can be an annular structure integrally formed on the inner wall of the connector 2. When the filter seat 3 is installed in the connector 2, the end of the filter seat 3 will abut against the annular limiting boss 22, thereby determining the axial position of the filter seat 3 in the connector 2 and ensuring the accuracy of the filter assembly installation.

[0040] Reference Figure 1 The three connectors include two or more different inner diameters, forming a reducing tee structure. By setting the reducing tee structure, the automotive tee connector can be adapted to pipelines of different specifications, enhancing the connector's versatility and applicability.

[0041] Reference Figure 1 The mounting base 1 has mounting holes 11 for bolt installation. The mounting holes 11 in the mounting base 1 of the automotive tee connector facilitate the installation of the tee connector into the appropriate position using bolts.

[0042] Example 2 Compared with Example 1, this embodiment is identical in structure to the automotive three-way connector in Example 1, except for the different installation methods of the filter frame and filter element.

[0043] Reference Figure 4 The filter frame 32 has an internal thread section on its inner wall, and the filter element 33 has an external thread section on its outer peripheral wall that mates with the internal thread section. The threaded connection between the filter element 33 and the filter frame 32 is provided with an elastic washer 333 for sealing. The elastic washer 333 is sleeved on the outer periphery of the filter element 33 and abuts against the inner end wall of the filter frame 32.

[0044] The implementation principle of the automotive tee connector 2 in this application embodiment is as follows: an automotive tee connector includes a mounting base 1 and a tee connector integrally disposed on the mounting base 1. The sliding part 31 on the outer wall of the filter seat 3 cooperates with the guide groove 21 on the inner wall of the connector 2. At the same time, the filter seat 3 is locked in the connector 2 by means of a locking structure, which can prevent impurities from accumulating at the connection of the tee connector 2 and causing blockage. In addition, the filter assembly is detachable, which is convenient for cleaning or replacement.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
