Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a horizontal connector. Background Technology

[0002] A horizontal connector is an electronic component whose core design principle lies in its horizontal mounting method (parallel to the PCB board), making it suitable for devices with limited space or requiring a low profile design.

[0003] Because horizontal connectors need to balance stability and high-density integration, they have stringent requirements for thickness and vibration resistance. Most existing horizontal connectors use a positioning press-fit sealing structure, which has low production efficiency and leads to reduced water resistance after long-term use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a horizontal connector with a compact structure and reliable sealing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] This application provides a horizontal connector, including an inner shell, a plastic die-casting part fixedly embedded in the inner shell, and an outer shell fixedly disposed on the inner shell;

[0007] An annular baffle is fixedly fitted at the first end of the inner shell, and a sealing ring is fixedly fitted on the annular baffle. The sealing ring is located on the second end of the annular baffle away from the plastic injection molded part.

[0008] Specifically, the sealing ring is integrally formed on the annular baffle.

[0009] Further specifying, in the above-mentioned horizontal connector, the annular baffle includes a mounting portion sleeved on the inner shell and a stop portion fixedly connected to the mounting portion;

[0010] Specifically, the sealing ring is integrally formed on the stop portion, and in the interlocking direction of the plastic two-shot part and the inner shell part, the projection of the stop portion covers the projection of the mounting part.

[0011] Further specifying, in the aforementioned horizontal connector, the outer housing is provided with at least one first solder point;

[0012] The outer shell and the plastic die-cast part are spot-welded together at the first welding point.

[0013] Further specifying, in the aforementioned horizontal connector, a locking part is fixedly provided on the outer shell, and the locking part can deformably lock onto the inner shell to limit the relative displacement of the outer shell and the inner shell in a predetermined direction;

[0014] Specifically, the predetermined direction refers to the embedding direction between the non-plastic die-cast part and the inner shell part.

[0015] Further specifying, the aforementioned horizontal connector also includes an EMC pad fixedly disposed on the plastic die-casting part and located between the plastic die-casting part and the inner shell part.

[0016] Further specifying, in the aforementioned horizontal connector, the EMC pad is sleeved on the plastic die-casting part and fastened to the plastic die-casting part.

[0017] Further specifying, in the above-mentioned horizontal connector, the EMC pad is provided with at least one retaining groove, and the plastic die-cast part is fixedly provided with at least one limiting protrusion;

[0018] The limiting protrusion can be engaged with the corresponding position groove.

[0019] Further specifying, in the aforementioned horizontal connector, the inner housing is provided with at least one second solder point;

[0020] The inner shell and EMC pads are spot-welded together at the second solder point.

[0021] Further specifying, in the above-mentioned horizontal connector, the inner shell is provided with an orientation part for orientation of the inner shell;

[0022] And / or, a sealing portion is provided between the plastic injection molded part and the inner shell part.

[0023] Further specifying, in the aforementioned horizontal connector, the annular baffle is provided with at least one third solder point;

[0024] The inner shell and the annular baffle are spot-welded together at the third welding point.

[0025] The present invention has at least the following beneficial effects:

[0026] 1. The sealing ring is integrally molded on the annular baffle, which has higher production efficiency compared to traditional assembly and liquid injection molding processes. At the same time, the integral molding structure can eliminate installation gaps and is not prone to deformation after long-term use, thus ensuring the stability and reliability of waterproof and sealing effects.

[0027] 2. Since the size of the annular baffle stop part is larger than the size of the mounting part, when the sealing ring is formed on the annular baffle, the stop part of the annular baffle can support the liquid UV adhesive, thereby ensuring the structural reliability of the sealing ring after it is formed.

[0028] 3. After the outer shell is installed on the inner shell, the locking part is riveted and deformed to limit the position between the outer shell and the inner shell, thereby ensuring the positional accuracy of the outer shell and the plastic two-shot part during welding;

[0029] 4. After the plastic die-casting part is fixedly connected to the EMC pad and embedded in the inner shell, the spot welding connection between the inner shell and the EMC pad is realized through the second welding point, so that the inner shell and the EMC pad are tightly combined, which not only improves the connection firmness and prevents loosening, but also improves the poor contact of the EMC pad.

[0030] 5. The glue seal achieves a fixed connection between the plastic die-casting part and the inner shell, which not only improves the overall structural strength of the connector, but also ensures the waterproof sealing performance between the plastic die-casting part and the inner shell.

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0044] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] The horizontal connector provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0046] like Figures 1 to 10 As shown, this application provides a horizontal connector, including an inner shell 300, a plastic die-casting part 200 fixedly embedded in the inner shell 300, and an outer shell 100 fixedly disposed on the inner shell 300.

[0047] An annular baffle 400 is fixedly sleeved on the first end of the inner shell 300, and a sealing ring 500 is fixedly installed on the annular baffle 400. The sealing ring 500 is located on the side of the annular baffle 400 away from the second end of the plastic die-cast part 200.

[0048] Specifically, the sealing ring 500 is integrally formed on the annular baffle 400.

[0049] Understandably, the sealing ring 500 can be configured to be formed on the annular baffle 400 by spraying liquid UV adhesive onto the annular baffle 400, thereby forming a solid waterproof ring structure after baking and drying.

[0050] In this embodiment, a horizontal connector as described above is used, with the sealing ring 500 integrally formed on the annular baffle 400. Compared with traditional assembly and liquid injection molding processes, this method has higher production efficiency. At the same time, the integrally formed structure can eliminate installation gaps and is less prone to deformation after long-term use, thereby ensuring the stability and reliability of waterproof and sealing effects.

[0051] In a preferred embodiment, such as Figures 1 to 4 , Figures 6 to 8 As shown, the annular baffle 400 includes a mounting portion sleeved on the inner shell 300 and a stop portion fixedly connected to the mounting portion.

[0052] Specifically, the sealing ring 500 is integrally formed on the stopping part of the annular baffle 400, and in the interlocking direction of the plastic two-shot part 200 and the inner shell part 300, the projection of the stopping part of the annular baffle 400 covers the projection of the mounting part.

[0053] Understandably, since the size of the stopping part of the annular baffle 400 is larger than the size of the mounting part, when the sealing ring 500 is formed on the annular baffle 400, the stopping part of the annular baffle 400 can support the liquid UV adhesive, thereby ensuring the structural reliability of the sealing ring 500 after it is formed.

[0054] In a preferred embodiment, such as Figure 2 As shown, the housing 100 has at least one first solder point 110.

[0055] The outer shell 100 and the plastic die-casting part 200 are spot-welded together at the first welding point 110.

[0056] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 5 As shown, a locking part 120 is fixedly provided on the outer casing 100.

[0057] The locking part 120 can deform and lock onto the inner shell 300 to limit the relative displacement of the outer shell 100 and the inner shell 300 in a predetermined direction, which is specifically the embedding direction between the non-plastic die-cast part 200 and the inner shell 300.

[0058] It is understandable that when the outer shell 100 is installed on the inner shell 300, the locking part 120 is riveted and deformed to achieve the limiting between the outer shell 100 and the inner shell 300, thereby ensuring the positional accuracy of the outer shell 100 and the plastic die-cast part 200 during welding.

[0059] In a preferred embodiment, such as Figure 9 , Figure 10 As shown, it also includes an EMC pad 700 fixedly disposed on the plastic die-casting part 200 and located between the plastic die-casting part 200 and the inner shell part 300.

[0060] It should be noted that EMC specifically stands for Electromagnetic Compatibility, and EMC pad 700 is used to protect electronic equipment from electromagnetic interference.

[0061] In a preferred embodiment, such as Figure 9 , Figure 10 As shown, the EMC pad 700 is fitted onto the plastic die-casting part 200 and is fastened to the plastic die-casting part 200.

[0062] In a preferred embodiment, such as Figure 9 , Figure 10 As shown, the EMC pad 700 is provided with at least one retaining groove 710, and the plastic die-cast part 200 is fixedly provided with at least one limiting protrusion 210.

[0063] The limiting protrusion 210 can be engaged with the corresponding position fastening groove 710.

[0064] It is understandable that the connection between the plastic die-casting part 200 and the EMC pad 700 is not limited to the one mentioned above. For example, a limiting protrusion 210 can be provided on the EMC pad 700, and a snap-fit ​​groove 710 can be provided on the plastic die-casting part 200. As long as quick release between the plastic die-casting part 200 and the EMC pad 700 can be achieved, it will not be elaborated here.

[0065] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 As shown, the inner shell 300 has at least one second weld point 310.

[0066] The inner shell 300 and the EMC pad 700 are spot welded together at the second solder point 310.

[0067] It is understandable that spot welding can be performed using laser welding, as long as spot welding can be achieved between the inner shell 300 and the EMC pad 700, which will not be elaborated here.

[0068] In a preferred embodiment, a set of second solder points 310 are provided on the opposite two end faces of the inner shell 300, and each set of second solder points 310 includes at least one second solder point 310.

[0069] Among them, the two sets of second weld points 310 are symmetrically arranged about the inner shell 300.

[0070] In this embodiment, a horizontal connector as described above is used. After the plastic die-casting part 200 is fixedly connected to the EMC pad 700 and embedded in the inner shell 300, the inner shell 300 and the EMC pad 700 are spot-welded together through the second solder point 310, so that the inner shell 300 and the EMC pad 700 are tightly combined. This not only improves the connection firmness and prevents loosening, but also improves the poor contact of the EMC pad 700.

[0071] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 As shown, each group of second solder joints 310 includes five second solder joints 310 arranged in a linear array.

[0072] In a preferred embodiment, such as Figure 8 As shown, the inner shell 300 is provided with a recognizing part 320 for recognizing the inner shell 300.

[0073] It is understandable that, since the inner shell 300 has a symmetrical structure, it is difficult to identify the front and rear directions during assembly. The orientation part 320 can identify the orientation of the inner shell 300 during assembly, thereby improving assembly efficiency.

[0074] The orientation part 320 can be a protrusion, a through hole, a surface marker, etc., as long as it can enable the orientation of the inner shell 300, which will not be elaborated here.

[0075] In a preferred embodiment, such as Figures 1 to 4 , Figure 6 , Figure 7 As shown, the annular baffle 400 is provided with at least one third welding point 410.

[0076] The inner shell 300 and the annular baffle 400 are spot welded together at the third welding point 410.

[0077] In a preferred embodiment, a set of third welding points 410 are respectively provided on the opposite two end faces of the annular baffle 400, and each set of third welding points 410 includes at least one third welding point 410.

[0078] Among them, the two sets of third welding points 410 are symmetrically arranged about the annular baffle 400.

[0079] It is understandable that the two sets of third welding points 410 can achieve a bidirectional fixed connection between the inner shell 300 and the annular baffle 400, thereby improving the connection strength between the inner shell 300 and the annular baffle 400.

[0080] In a preferred embodiment, such as Figure 4As shown, a sealing part 600 is provided between the plastic injection molded part 200 and the inner shell part 300.

[0081] Understandably, when the plastic die-casting part 200 is embedded in the inner shell part 300, glue can be poured into the inner shell part 300 to form a glue seal part 600. The glue seal part 600 realizes the fixed connection between the plastic die-casting part 200 and the inner shell part 300, which not only improves the overall structural strength of the connector, but also ensures the waterproof sealing performance between the plastic die-casting part 200 and the inner shell part 300.

[0082] In a preferred embodiment, at least one of the outer shell 100, inner shell 300, annular baffle 400, and EMC pad 700 is made of stainless steel.

[0083] Understandably, the annular baffle 400 is made of stainless steel and is welded to the inner shell 300 by laser spot welding, which is more robust and aesthetically pleasing than the traditional plastic molding structure.

[0084] During assembly, the annular baffle 400 is first fitted onto the inner shell 300 and the two are spot-welded together. Then, a sealing ring 500 is integrally formed on the annular baffle 400. At the same time, the EMC pad 700 is fitted onto the plastic double-shot part 200. After the plastic double-shot part 200 is embedded in the inner shell 300, the inner shell 300 and the EMC pad 700 are spot-welded together. A seal 600 is formed between the plastic double-shot part 200 and the inner shell 300. Finally, the outer shell 100 is installed on the inner shell 300 and the outer shell 100 and the inner shell 300 are spot-welded together. The locking part 120 is riveted to deform and lock the plastic double-shot part 200.
