Description

Technical Field

[0001] This utility model relates to the technical field of electrical connector processing equipment, and in particular to a mold for applying glue to the terminals of aviation plugs. Background Technology

[0002] Aviation plugs are a common name for electrical connectors, also known as aviation connectors or aviation electrical connectors. They are named after their original use in the aviation field. They are generally used in conjunction with aviation sockets and are now widely used in fields such as marine, aerospace, aviation, defense, military, nuclear industry, and power. Their shells are often made of metal materials such as magnesium-aluminum alloy and stainless steel, making them sturdy and durable.

[0003] Existing aviation connectors generally include a metal shell, a terminal assembly housed within the metal shell, and a wire harness that is soldered to the terminal assembly and extends from the rear port of the metal shell. In existing technologies, the solder joints between the wire harness and the terminal assembly are often processed and wrapped manually with glue to improve the protection level. Manual glue application relies entirely on the operator's personal experience, which requires high skill from the operator, is labor-intensive, inefficient, and results in significant variations in the shape of the glue, making it unsuitable for mass production. Utility Model Content

[0004] The present invention aims to overcome the defects in the prior art by providing a mold for applying glue to the terminals of aviation plugs. When the upper template assembly is in the open state, it facilitates the taking and placing of aviation plugs; when the upper template assembly is in the closed state, it facilitates glue application and produces a consistent glue, making it suitable for mass production of aviation plugs.

[0005] To achieve the above objectives, this utility model provides a mold for applying glue to the terminals of an aviation plug, comprising a lower template, an upper template assembly, and a locking assembly; The upper surface of the lower template is provided with at least one receiving cavity for the overall embedding of the aviation plug; The upper template assembly includes a left module and a right module that are rotatably connected to the left and right sides of the lower template, respectively. The upper template assembly can switch between a closed state and an open state by rotating the left module and the right module toward each other or away from each other. When the upper template assembly is in the mating state, the right side of the left module and the left side of the right module are attached to each other, and their lower surfaces are attached to the upper surface of the lower template. At the same time, the right side of the left module and the left side of the right module are mated to form an upper mold cavity that corresponds one-to-one with the accommodating cavity on the lower template and is vertically connected. The upper mold cavity includes a molding cavity located at the lower part and an outlet port connected to the upper port of the molding cavity. The upper template assembly is also provided with an injection channel that extends obliquely from the upper surface to the molding cavity. The locking component is used to lock the upper template component in an aligned state.

[0006] The glue injection channel is further configured such that it is located on the left module or the right module, or the glue injection channel is formed by the right side of the left module and the left side of the right module.

[0007] The method is further configured such that the glue injection channel includes a tapered section that is directly connected to the molding cavity and whose diameter gradually decreases.

[0008] The configuration is further defined as follows: a first recessed structure is provided on the right side of the left module, and a corresponding second recessed structure is provided on the left side of the right module, wherein the first recessed structure and the second recessed structure are symmetrical structures.

[0009] The locking component is further configured to include a U-shaped member, which restricts opening by being fitted over the left and right modules in the engaged state.

[0010] A further configuration is made such that when the aviation plug is embedded in the receiving cavity of the lower template, the rear end face of the metal shell of the aviation plug is flush with the upper surface of the lower template.

[0011] The molding cavity is further configured as follows: the lower port is large, the upper port is small, and the area between the lower and upper ports gradually decreases.

[0012] The following configuration is further defined: the lower port diameter of the molding cavity is smaller than the upper port diameter of the receiving cavity.

[0013] The lower template is further configured such that a boss is provided at the center of its upper surface; The left module has a first lug on the outer side of the corresponding boss at both ends, and the two first lugs are connected to the boss by a rotating shaft. The right module has a second lug on the outer side of the corresponding boss at both ends, and the two second lugs are connected to the boss by a rotating shaft.

[0014] Compared with the existing technology, this utility model greatly improves the glue application efficiency of aviation plugs by using a special mold, and the glue formed by the glue application has good consistency, which can be applied to the mass production of aviation plugs.

[0017] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0018] This utility model discloses a mold for applying adhesive to the terminals of an aviation plug. It is used for applying adhesive to the solder joints between the terminal assembly of the aviation plug 60 and the wire harness 62. In this embodiment, a cylindrical aviation plug 60 (such as...) is used. Figure 4 Let's take an example to illustrate this.

[0019] This utility model discloses a mold for applying glue to the terminals of aviation plugs, such as... Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes a lower template 10, an upper template assembly 20, and a locking assembly 50. The upper surface of the lower template 10 is provided with at least one cylindrical receiving cavity 11 for the overall embedding of the aviation plug 60 (in this embodiment, the lower template 10 is provided with two receiving cavities 11). The upper template assembly 20 includes a left module 30 and a right module 40 rotatably connected to the left and right sides of the lower template 10, respectively. The upper template assembly 20 can switch between an engaged state and an open state by rotating the left module 30 and the right module 40 towards each other or away from each other. When the upper template assembly 20 is in the engaged state, it is suitable for applying glue. When the upper template assembly 20 is in the open state, it is suitable for taking off and placing the aviation plug 60. The locking assembly 50 is used to securely lock the upper template assembly 20 in the engaged state.

[0020] In the above scheme, the lower template 10 is provided with a boss 12 at the middle of its upper surface; the two ends of the left module 30 are provided with first lugs 33 on the outer sides of the two ends of the boss 12, and the two first lugs 33 are rotatably connected to the boss 12 through a rotating shaft; the two ends of the right module 40 are provided with second lugs 43 on the outer sides of the two ends of the boss 12, and the two second lugs 43 are rotatably connected to the boss 12 through a rotating shaft.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, when the upper template assembly 20 is in the mating state, the right side 31 of the left module 30 and the left side 41 of the right module 40 are mated together, and their lower surfaces are mated on the upper surface of the lower template 10. At this time, the upper template assembly 20 is installed as a whole on the lower template 10. The upper template assembly 20 forms an upper mold cavity that corresponds one-to-one with the receiving cavity 11 on the lower template 10 and is vertically connected between the right side 31 of the left module 30 and the left side 41 of the right module 40. The central axis of the upper mold cavity is collinear with the central axis of the receiving cavity 11. The mold cavity includes a molding cavity 21 located at the bottom and communicating with the receiving cavity 11, and a wire outlet 22 connected to the upper port of the molding cavity 21 and extending to the upper surface. The upper mold assembly 20 is also provided with an injection channel 23 that extends obliquely from the upper surface to the molding cavity 21 for each upper mold cavity. The molding cavity 21 is used to define the shape of the glue 63 after the aviation plug 60 is glued. The molding cavity 21 is preferably a conical structure with a large lower port, a small upper port, and a gradual narrowing between the lower and upper ports. The wire outlet 22 is used for the wire harness 62 of the aviation plug 60 to extend out.

[0022] In this embodiment, as Figure 3 As shown, a first recessed structure 32 is provided on the right side 31 of the left module 30, and a second recessed structure 42 opposite to the first recessed structure 32 is provided on the left side 41 of the right module 40. The first recessed structure 32 and the second recessed structure 42 are matched to form an upper mold cavity. Preferably, the first recessed structure 32 and the second recessed structure 42 are symmetrical structures.

[0023] In this embodiment, the glue injection channel 23 on the upper template assembly 20 is also formed by the first recessed structure 32 and the second recessed structure 42, which facilitates the cleaning of residues in the glue injection channel 23; in some other specific embodiments, the glue injection channel 23 can also be directly constructed on the left module 30 or the right module 40.

[0024] In this embodiment, the glue injection channel 23 includes a tapered tapered section 231 that is directly connected to the molding cavity 21 and has a gradually decreasing diameter. In this way, the tapered section 231 can form a thin and strong glue line during the glue application process to better fill the metal shell 61 of the aviation plug 60 and the molding cavity 21.

[0025] In this embodiment, when the aviation plug 60 is embedded in the receiving cavity 11 of the lower template 10, the rear end face of the metal shell 61 of the aviation plug 60 is flush with the upper surface of the lower template 10. At the same time, the lower port diameter of the molding cavity 21 is smaller than the upper port diameter of the receiving cavity 11. Thus, the glue 63 formed by applying glue can be flush with the rear end face of the metal shell 61, making the shape of the glue 63 more aesthetically pleasing.

[0026] In this embodiment, the locking component 50 includes a U-shaped component 51, which restricts opening by being fitted onto the left and right modules 40 in the mated state. Preferably, both the left module 30 and the right module 40 are provided with positioning notches for positioning and inserting the U-shaped component 51.

[0027] Compared with the existing technology, this utility model greatly improves the glue application efficiency of aviation plugs by using a special mold, and the glue formed by the glue application has good consistency, which can be applied to the mass production of aviation plugs.

[0028] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
