Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency connector gaskets, in particular to a gasket for a connector. Background Art

[0002] With the advancement of science and technology, market requirements for connectors are becoming increasingly diverse, especially in the communications system sector. However, as market demand shrinks, customers are placing increasing demands on product quality and cost. During the production process, connectors typically have a pre-set hole for welding and other operations. After the connector is assembled, a gasket is used to seal the hole.

[0003] The gaskets currently used in the market are generally machined parts produced by lathes, and their product shapes (this shape corresponds to the shape of the machined holes on the connector) are mostly circular. Before leaving the factory for use, a certain batch of multiple gaskets are generally placed in an electroplating bath for electroplating. Since the gaskets are circular and flat, any two adjacent gaskets will be fitted together in surface contact, that is, the gaskets will not be fully surrounded by the electroplating solution. During the electroplating process, the flat fitting of any two adjacent gaskets will cause poor electroplating, resulting in poor electroplating effect of the gaskets, and the quality of the gaskets will also deteriorate. In subsequent use, the service life of the gaskets is short and cannot meet the use requirements.

[0004] At the same time, due to the small diameter of the machining hole on the connector, the gasket cannot be connected to the connector using bolts or other methods. It can only be sealed by placing a gasket in the machining hole and then stamping it. Therefore, there are certain requirements for the adaptation relationship between the gasket and the machining hole diameter. The gasket needs to be able to completely seal the machining hole during the stamping process. Due to the limitations of existing lathe production technology, it is difficult to accurately adapt the size design of the gasket to the machining hole diameter. When the gasket size is larger than the machining hole diameter, burrs will be generated around the gasket during the assembly process. If the burrs are not properly treated, the burrs may contact the center conductor inside the connector and cause a short circuit, causing the connector to be scrapped. When the gasket size is smaller than the machining hole diameter, after the gasket is stamped so that the gasket contacts the inner wall of the machining hole, the gap between the gasket and the machining hole is large in the initial state, and the contact connection is unstable. When subjected to external machining vibrations, the gasket may fall out of the machining hole, affecting the production quality of the connector.

[0005] Therefore, we propose a connector gasket to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to solve the problems in the prior art and to propose a gasket for a connector. By providing a curved surface on the gasket body, the gasket body can produce radial deformation when being punched in the processing hole, so that the four sides of the gasket body can be in stable contact with the inner wall of the processing hole; at the same time, by providing a convex portion, point contact is made between the two gasket bodies stacked in the electroplating tank, ensuring that the electroplating liquid can cover the entire gasket body, so that the gasket body is well electroplated.

[0007] In order to solve the above problems, the present invention provides the following technical solutions:

[0008] A connector gasket includes a gasket body having an arched area adapted to a processing hole shape so that the gasket body produces a radially outward deformation when punched in the processing hole. The gasket body is provided with a plurality of protrusions so that two gasket bodies in a stacked state are in point contact.

[0009] As a further solution of the present invention: the gasket body is arranged in an arc shape as a whole to form the arched area, and the arch back of the arched area constitutes the stamping area.

[0010] As a further solution of the present invention: a plurality of the protrusions are arranged on the inner side of the gasket body.

[0011] As a further solution of the present invention: the outer side of the gasket body is recessed toward the inner side thereof to form the single-point convex portion.

[0012] As a further solution of the present invention: the convex portion is arranged at the center position of the gasket body.

[0013] As a further solution of the present invention: it also includes an outer profile arranged on the outer edge of the gasket body, and a plurality of the protrusions are arranged on the outer profile.

[0014] As a further solution of the present invention: one side of the outer profile is recessed from the other side thereof to form the convex portion.

[0015] As a further solution of the present invention: the outer profile and the gasket body are integrally formed.

[0016] As a further solution of the present invention: the number of the convex portions is four, and the four convex portions are evenly distributed on the outer contour.

[0017] As a further solution of the present invention: the outer profile is annular, and the outer profile is coaxially arranged with the gasket body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By setting the arched area, after the gasket body is placed inside the processing hole, it is stamped. The arched area is subjected to force, causing the gasket body to deform radially outward, so that the gasket body can be closely contacted with the inner wall of the processing hole around it, ensuring the gasket body's sealing effect on the processing hole;

[0020] 2. Through the setting of the convex part, after placing multiple gasket bodies in the electroplating tank, the two stacked gasket bodies are in point contact due to the presence of the convex part. This small area of contact can maximize the electroplating liquid to surround the gasket body, thereby ensuring the electroplating effect and extending the life of the gasket body.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-Figure 3 As shown, a connector gasket includes a gasket body 1, which has an arched area adapted to the processing hole type, so that the gasket body 1 produces a radially outward deformation when being punched in the processing hole a. Figure 2 In the state shown, the gasket body 1 is moved to the right until it is located inside the processing hole a. At this time, the gasket body 1 can be stamped. During the stamping process, the arched area will be squeezed and deformed toward the inside of the connector b. After squeezing, the state of the gasket body 1 can be changed from Figure 3 To illustrate, at this time, the gasket body 1 produces a radially outward deformation, and the outer edge of the gasket body 1 will be tightly fitted and pressed against the inner wall of the processing hole a, ensuring that the gasket body 1 well seals the processing hole a.

[0031] Furthermore, the gasket body 1 is arranged as a whole in an arc shape to form the above-mentioned arched area, and the arch back of the arched area constitutes a stamping area. During the stamping process, the external stamping components act on the stamping area.

[0032] like Figure 1 As shown, in order to maximize the surrounding of the two stacked gasket bodies 1 by the electroplating liquid during the electroplating process, a number of protrusions 2 can be provided on the gasket body 1. The protrusions 2 are provided to enable point contact between the two stacked gasket bodies 1. This point contact method can maximize the minimum contact area between the two adjacent gasket bodies 1, thereby allowing the electroplating liquid to completely cover the outside of the gasket body 1, so that good electroplating work can be carried out subsequently.

[0033] Preferably, several protrusions 2 are disposed on the inner side of the gasket body 1, with the protrusion 2 being located at the center of the gasket body 1. When two gasket bodies 1 are stacked, the protrusions 2 separate them, creating a point contact pattern with a small contact area, facilitating subsequent electroplating. Furthermore, due to the relatively small size of the gasket body 1, the protrusions 2 are typically recessed from the outer side of the gasket body 1 toward the inner side, forming a single point-shaped protrusion 2.

[0034] Example 2:

[0035] like Figure 4-Figure 5 As shown, the difference between this embodiment and the first embodiment is that this embodiment is optimized and improved on the basis of the first embodiment, specifically as follows: an outer profile 3 is integrally formed at the outer edge of the gasket body 1. When the outer profile 3 exists, a plurality of protrusions 2 are provided on the outer profile 3. With respect to the design of the protrusions 2, one side of the outer profile 3 can be recessed from the other side to form the protrusions 2.

[0036] Figure 4-Figure 5The illustrated embodiment shows four protrusions 2 evenly distributed on the outer profile 3, and the outer profile 3 is annular and coaxial with the gasket body 1. This annular outer profile 3 is compatible with the circular machining hole a. In actual production, the shape of the outer profile 3 is not limited to annular, as long as the shape of the outer profile 3 is compatible with the hole shape of the machining hole a. Furthermore, the number of protrusions 2 is not limited to the four shown in the figure; five or six, etc., can also be provided, as long as point contact is achieved between the two stacked gasket bodies 1.

[0037] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
