Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to a connector. Background Technology

[0002] Acoustic components (such as hearing aids) typically include a controller and a receiver, which is used to emit sound. There is usually a connecting cable between the receiver and the controller, with a plug at one end of the cable that connects to a connector on the controller.

[0003] In related technologies, connectors generally include an insulating base and an insulating body. The insulating body is provided with connecting terminals, which are used to connect to a plug, thereby achieving an electrical connection between the connector and the plug. The insulating body and the insulating base are fixedly connected by a bump-slot structure; that is, the insulating base has bumps, and the insulating body has slots that mate with the bumps, or vice versa. Because the size of the insulating base and body is relatively small, the bump-slot structure is limited by the size of the insulating base and body, resulting in poor fit between the bumps and slots. This leads to poor connection stability between the insulating body and the insulating base, resulting in lower structural strength of the connector and even affecting its electrical stability. Utility Model Content

[0004] This application provides a connector to solve the technical problem that the connection stability between the insulating body and the insulating base of existing connectors is poor, resulting in low structural strength of the connector and even affecting the electrical stability of the connector.

[0005] This application provides a connector, including:

[0006] The housing has a receiving cavity for connecting a plug, and the housing also has a groove.

[0007] An electrical connection part is provided for electrical connection with the plug. The electrical connection part includes a body. A boss is provided on the side of the body facing the housing for insertion and connection with the groove. A first adhesive part is provided on both sides of the boss in the length direction of the body. The first adhesive part is used to connect the boss and the housing.

[0008] In one possible implementation, the first adhesive portion includes a first adhesive groove and an adhesive disposed in the first adhesive groove, the housing has a first wall surface at the groove, and the boss includes a second wall surface and a third wall surface connected together, the first wall surface, the second wall surface and the third wall surface surrounding to form the first adhesive groove.

[0010] In one possible implementation, the body is provided with a limiting groove for fixing the connecting terminal, and the limiting groove is provided with an interference portion that is interference-fitted with the connecting terminal.

[0011] In one possible implementation, the outer surface of the body is provided with a second adhesive portion, the second adhesive portion including a second adhesive groove and an adhesive disposed in the second adhesive groove, the second adhesive portion being used to connect the body and the connecting terminal.

[0012] In one possible implementation, a plurality of limiting portions are provided on the side of the body away from the housing, and the plurality of limiting portions are respectively provided on both sides of the body. The limiting portions are used to abut against the two side edges of the control circuit board to limit the displacement of the control circuit board.

[0013] In one possible implementation, the body has a fourth wall surface on the side away from the housing, the welded portion protrudes relative to the fourth wall surface, and the limiting portion protrudes relative to the fourth wall surface on the side away from the body.

[0014] In one possible implementation, the fourth wall surface is provided with arc-shaped protrusions.

[0015] In one possible implementation, a locking part is provided in the accommodating cavity of the housing, and a snap-fit ​​part is provided on the outside of the plug. The locking part is used to cooperate with the snap-fit ​​part to snap and fix a portion of the plug in the accommodating cavity.

[0016] In one possible implementation, a cover is also included, which covers the side of the housing away from the body and is sealed to the accommodating cavity.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] This application provides a connector in which the plug extends into the receiving cavity of the housing, and the end of the plug with the PIN pin is inserted into the electrical connection part of the connector to achieve electrical connection. Since the boss has first adhesive portions on both sides of the body along its length, the boss and the housing are connected through these first adhesive portions. Both sides of the boss can be connected to the housing through the first adhesive portions, thereby increasing the connection area between the boss and the housing, improving the connection stability between the body and the housing, and enhancing the structural strength of the connector. During the plug-to-connector insertion process and use, the electrical connection part is prevented from detaching from the housing due to external force, ensuring that the PIN pin of the plug is always connected to the electrical connection part, thus improving the electrical stability of the connector and ensuring the normal operation of the acoustic components.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0043] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0044] In related technologies, connectors generally include an insulating base and an insulating body. The insulating body is provided with connecting terminals, which are used to connect to a plug, thereby achieving an electrical connection between the connector and the plug. The insulating body and the insulating base are fixedly connected by a bump-slot structure; that is, the insulating base has bumps, and the insulating body has slots that mate with the bumps, or vice versa. Because the size of the insulating base and body is relatively small, the bump-slot structure is limited by the size of the insulating base and body, resulting in poor fit between the bumps and slots. This leads to poor connection stability between the insulating body and the insulating base, resulting in lower structural strength of the connector and even affecting its electrical stability.

[0045] To address the technical problem of poor connection stability between the insulating body and the insulating base of existing connectors, which leads to low structural strength and even affects the electrical stability of the connector, this application provides a connector that improves the connection stability between the body and the housing, enhances the structural strength of the connector, and prevents the electrical connection part from detaching from the housing due to external force during the plug-to-connector insertion process and use. This ensures that the PIN pins of the plug are always connected to the electrical connection part, thereby improving the electrical stability of the connector and ensuring the normal operation of the acoustic components.

[0046] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a connector 100, including a housing 10 and an electrical connection part 20. The housing 10 is provided with a receiving cavity 11 for connecting a plug (not shown in the figure), and the housing 10 is provided with a groove 12. The electrical connection part 20 is used for electrical connection with the plug. The electrical connection part 20 includes a body 21. The body 21 is provided with a boss 211 connected to the groove 12 on the side facing the housing 10. The boss 211 is provided with a first adhesive part 212 on both sides of the body 21 along the length direction. The first adhesive part 212 is used to connect the boss 211 and the housing 10.

[0047] Specifically, the end of the housing 10 away from the electrical connection portion can be configured as a heart-shaped cylindrical structure to guide the plug. The boss 211 and the body 21 can be integrally formed.

[0048] For ease of explanation and understanding, the length direction of the body 21 can be the X direction shown in the figure, and the width direction of the body 21 can be the Y direction shown in the figure. The body 21 is generally rectangular, therefore, the length direction and the width direction of the body 21 are perpendicular to each other. It can be understood that after the plug is inserted into the receiving cavity 11 of the housing 10, the end of the plug with the PIN pin is inserted into the electrical connection part 20 of the connector 100 to achieve electrical connection. Since the boss 211 is provided with a first adhesive portion 212 on both sides of the body 21 along its length, the boss 211 and the housing 10 are connected by the first adhesive portion 212. Both sides of the boss 211 can be connected to the housing 10 through the first adhesive portion 212, thereby increasing the connection area between the boss 211 and the housing 10, improving the connection stability between the body 21 and the housing 10, and enhancing the structural strength of the connector 100. During the insertion process of the plug and the connector 100 and during use, the electrical connection portion 20 is prevented from falling off the housing 10 due to external force, ensuring that the PIN pin of the plug is always connected to the electrical connection portion 20, thereby improving the electrical stability of the connector 100 and ensuring the normal operation of the acoustic components.

[0049] It should be noted that both the housing 10 and the body 21 can be made of materials with good insulation properties, such as plastic.

[0050] In some embodiments, such as Figure 3 and Figure 4 As shown, the first adhesive portion 212 includes a first adhesive groove 212a and an adhesive disposed within the first adhesive groove 212a. The housing 10 has a first wall surface 13 at the groove 12, and the boss 211 has a connected second wall surface 211a and a third wall surface 211b. Both the second wall surface 211a and the third wall surface 211b can be located on the outer surface of the boss 211. The first wall surface 13, the second wall surface 211a, and the third wall surface 211b surround and form the first adhesive groove 212a, which forms an inwardly recessed groove relative to the housing 10. During the assembly process of the connector 100, after the boss 211 is snapped into the groove 12 of the housing 10, as shown... Figure 4 As shown, adhesive is filled into the first bonding groove 212a, and the adhesive fully contacts the first wall surface 13, the second wall surface 211a, and the third wall surface 211b. After the adhesive cures in the first bonding groove 212a, a first bonding portion 212 is formed, as shown. Figure 1 As shown, the body 21 and the housing 10 can be effectively fixed, thereby improving the connection stability between the body 21 and the housing 10.

[0051] In some embodiments, such as Figure 5 and Figure 6 As shown, the main body 21 is provided with a socket 213 communicating with the accommodating cavity 11. Multiple connection terminals 22 are respectively provided on both sides of the socket 213 in the width direction of the main body 21. One end of the connection terminal 22 is located outside the main body 21 and is provided with a welding part 221, which is used to weld to the control circuit board 200. The other end of the connection terminal 22 is located inside the socket 213 and is provided with a protrusion 222, which is used to contact the plug.

[0052] Specifically, the connecting terminal 22 is a metal part. The end of the plug with the PIN pin is sequentially inserted into the receiving cavity 11 of the housing 10 and the socket 213 of the electrical connection part 20, and the end of the plug with the PIN pin contacts the connecting terminal 22 to achieve electrical connection. The protrusion 222 can be set as an arc-shaped protrusion, which can position the end of the plug with the PIN pin, so that the end of the plug with the PIN pin is always in contact with the connecting terminal 22. One end of the connecting terminal 22 is located on the outside of the body 21 and is provided with a soldering part 221. The soldering part 221 is used to solder to the corresponding control circuit board 200 of the controller, so that after the socket is inserted into the connector 100, the socket can be connected to the control circuit board 200 in the controller.

[0053] In some embodiments, such as Figure 7As shown, the main body 21 is provided with a limiting groove 214 for fixing the connecting terminal 22. An interference portion 214a, which is interference-fitted with the connecting terminal 22, is provided within the limiting groove 214. Multiple limiting grooves 214 are provided, each corresponding to a different connecting terminal 22. The limiting groove 214 can accommodate the connecting terminal 22 and limit its movement. By providing the interference portion 214a, which can be configured as a protrusion extending beyond the limiting groove 214, the connecting terminal 22 is fixed, preventing it from falling off the limiting groove 214.

[0054] In some embodiments, such as Figure 8 As shown, a second adhesive portion 215 is provided on the outer surface of the main body 21, such as... Figure 7 As shown, the second adhesive portion 215 includes a second adhesive groove 215a and an adhesive disposed within the second adhesive groove 215a. The second adhesive portion 215 is used to connect the body 21 and the connecting terminal 22. During the assembly process of the connector 100, after the connecting terminal 22 is snapped onto the limiting groove 214 of the body 21, as shown... Figure 5 As shown, adhesive is then filled into the second bonding groove 215a, ensuring full contact between the adhesive and the connecting terminal 22. After the adhesive cures within the second bonding groove 215a, a second bonding portion 215 is formed, as shown. Figure 8 As shown, the main body 21 and the connecting terminal 22 can be effectively fixed, thereby improving the connection stability.

[0055] In some embodiments, such as Figure 8 As shown, a plurality of limiting portions 216 are provided on the side of the main body 21 away from the housing 10. These limiting portions 216 are respectively disposed on both sides of the main body 21. The limiting portions 216 are used to abut against the side edges of the control circuit board 200 to limit the displacement of the control circuit board 200. Specifically, there may be two, four, six, etc., limiting portions 216; this application does not impose a specific limitation. In one example, such as... Figure 9 As shown, four limiting portions 216 are provided, with two limiting portions 216 forming a group, and the two groups of limiting portions 216 are respectively provided on both sides of the body 21 along its length direction. During the welding process between the welding portion 221 of the connecting terminal 22 and the control circuit board 200, the limiting portions 216 abut against the two side edges of the control circuit board 200, thereby limiting the displacement of the control circuit board 200 in the length direction of the body 21, facilitating welding; or, the two groups of limiting portions 216 are respectively provided on both sides of the body 21 along its width direction, and the limiting portions 216 abut against the two side edges of the control circuit board 200, thereby limiting the displacement of the control circuit board 200 in the width direction of the body 21, facilitating welding.

[0056] In some embodiments, such as Figure 9 and Figure 10As shown, the body 21 has a fourth wall surface 217 on the side away from the housing 10. The welding portion 221 protrudes relative to the fourth wall surface 217, and the limiting portion 216 protrudes relative to the fourth wall surface 217 on the side away from the body 21. The welding portion 221 protrudes relative to the fourth wall surface 217 to improve the coplanarity of the connecting terminals 22 after welding. The limiting portion 216 protrudes relative to the fourth wall surface 217 on the side away from the body 21, which can restrict the displacement of the control circuit board 200, improve the welding stability between the control circuit board 200 and the welding portion 221, and thus ensure the coplanarity of the connecting terminals 22 after welding.

[0057] Furthermore, such as Figure 9 and Figure 10 As shown, the fourth wall surface 217 is provided with an arc-shaped protrusion 218. By providing the arc-shaped protrusion 218, the arc-shaped protrusion 218 can abut against the side of the control circuit board 200 facing the body 21, preventing the control circuit board 200 from excessively squeezing the connection terminal 22, causing the connection terminal 22 to detach from the body 21.

[0058] In some embodiments, such as Figure 11 As shown, a locking part 14 is provided in the receiving cavity 11 of the housing 10, and a snap-fit ​​part is provided on the outside of the plug. The locking part 14 is used to cooperate with the snap-fit ​​part to snap and fix a part of the plug in the receiving cavity 11. Specifically, the locking part 14 can be configured as a protrusion, and the snap-fit ​​part can be configured as a slot. After the plug is inserted into the receiving cavity 11, the snap-fit ​​part and the locking part 14 engage to lock and fix the plug.

[0059] In some embodiments, such as Figure 12 As shown, the connector 100 also includes a cover 23, which covers the side of the housing 10 away from the body 21 and is sealed to the receiving cavity 11. The cover 23 serves to seal and prevent dust. When the connector 100 needs to be used, the cover 23 is removed and the plug is inserted into the connector 100.
