Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a connector with a semi-enclosed structure. Background Technology

[0002] The existing electrical connector structure mainly includes a housing, terminal group and circuit board. The terminal group is embedded in the insulator, the housing is wrapped around the outside of the insulator, and the circuit board is set at one end of the housing and soldered to the terminal group. The circuit board is used to assemble and use the electrical connector with wires, smart devices or other components.

[0003] However, the existing connection between the terminal and the circuit board relies solely on the solder joint for support. This makes it easy for the terminal and circuit board to loosen during subsequent use due to bending or external pulling, thus affecting the lifespan of the electrical connector. Utility Model Content

[0004] The purpose of this invention is to provide a connector with a semi-enclosed structure, which strengthens the connection between the terminal group and the circuit board.

[0005] The technical solution adopted by the semi-enclosed connector disclosed in this utility model is: A semi-enclosed connector includes a housing, a terminal group, and a circuit board. One end of the terminal group is soldered to the surface of the circuit board. The surface of the terminal group is covered with a first insulator. The housing is fitted onto the surface of the first insulator. The connector is characterized in that a second insulator is provided at the solder joint between the terminal group and the circuit board. The second insulator covers the upper and lower surfaces of the circuit board respectively. The end of the housing near the circuit board extends to cover the surface of one end of the second insulator. The surface of the second insulator has a protrusion. The housing has a corresponding groove for the protrusion, and the protrusion engages with the groove to form a limiting position.

[0006] As a preferred embodiment, the circuit board surface is provided with electronic components, and the second insulator extends to cover the surface of the electronic components.

[0007] As a preferred embodiment, the circuit board surface is provided with a plurality of connection contacts arranged in a row, and the second insulator forms a clearance between the connection contacts.

[0008] As a preferred embodiment, the housing extends to both sides of one end of the housing and has notches. The circuit board has a convex structure, and the two sides of the circuit board are correspondingly inserted into the notches. The circuit board has grounding contacts corresponding to the notches, and the grounding contacts are in contact with the housing.

[0009] As a preferred embodiment, the terminal assembly includes a plurality of conductive terminals and a hook. The plurality of conductive terminals are arranged in two rows opposite each other and are arranged along the width direction of the circuit board. The hook is arranged horizontally between the two rows of conductive terminals, and the middle part of the hook makes contact with the end of the circuit board near the terminal group.

[0010] As a preferred embodiment, the hook has protrusions extending from both sides toward one end of the circuit board, the protrusions corresponding to the two sides of the protruding part of the circuit board, and there is a gap between the protrusions and the circuit board, the protrusions being embedded in the second insulator.

[0011] As a preferred embodiment, the second insulator is stepped, and the surface of the second insulator extending out of the shell is at the same horizontal plane as the surface of the shell.

[0012] The beneficial effects of the semi-enclosed connector disclosed in this utility model are as follows: by setting a second insulator at the welding point of the terminal group and the circuit board, the second insulator is used to wrap the terminal group circuit board, thereby increasing the connection strength at the welding point. Furthermore, one end of the shell extends to cover the surface of the second insulator, and the protrusions on the second insulator are used to fit into the slots of the shell to form a limit, which improves the connection stability between the shell and the second insulator. At the same time, the shell can also be used to reinforce the connection between the second insulator and the first insulator, thereby improving the overall strength of the connector.

[0019] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figures 1 to 6A semi-enclosed connector includes a housing 10, a terminal group 20, and a circuit board 30. One end of the terminal group 20 is soldered to the surface of the circuit board 30. The surface of the terminal group 20 is covered with a first insulator 40. The housing 10 is sleeved on the surface of the first insulator 40. A second insulator 50 is provided at the solder joint between the terminal group 20 and the circuit board 30. The second insulator 50 covers the upper and lower surfaces of the circuit board 30 respectively. The end of the housing 10 near the circuit board 30 extends to cover the surface of one end of the second insulator 50. The surface of the second insulator 50 is provided with a protrusion 51. The housing 10 is provided with a slot 11 corresponding to the protrusion 51. The protrusion 51 is inserted into the slot 11 to form a limit.

[0020] In this embodiment, the connector structure is specifically a TYPE-C connector, but it is not limited to this connector. By setting a second insulator 50 at the solder joint between the terminal group 20 and the circuit board 30, the second insulator 50 is used to wrap the terminal group 20 and the circuit board 30, thereby increasing the connection strength at the solder joint. Furthermore, one end of the housing 10 extends to cover the surface of the second insulator 50, and the protrusion 51 on the second insulator 50 is used to engage with the slot 11 of the housing 10 to form a limit, thereby improving the connection stability between the housing 10 and the second insulator 50. At the same time, the housing 10 can also be used to reinforce the connection between the second insulator 50 and the first insulator 40, thereby improving the overall strength of the connector.

[0021] In the above scheme, electronic components are provided on the surface of the circuit board 30, and the second insulator 50 extends to cover the surface of the electronic components. The second insulator 50 can protect the electronic components, improve waterproof and dustproof performance, and improve the bending strength of the circuit board 30.

[0022] The circuit board 30 has a number of connection contacts 31 arranged on its surface. The second insulator 50 forms a clearance corresponding to the connection contacts 31. The connection contacts 31 can be used for assembly and soldering with wires or other equipment.

[0023] Please refer to Figure 2 The housing 10 extends to both sides of one end of the housing 10 and has notches 12. The circuit board 30 has a convex structure and the two sides of the circuit board 30 are inserted into the notches 12. The housing 10 supports the two sides of the circuit board 30, which further improves the bending resistance between the circuit board 30 and the terminal group 20. The circuit board 30 has a grounding contact 32 corresponding to the notch 12. The grounding contact 32 contacts the housing 10, so that the circuit board 30 and the housing 10 form a grounding connection, which facilitates the use of the housing 10 for grounding in subsequent use.

[0024] Please refer to Figure 4The terminal group 20 includes several conductive terminals 2121 and hooks 22. The conductive terminals 2121 are arranged in two rows, one above the other, along the width of the circuit board 30. The hooks 22 are arranged laterally between the two rows of conductive terminals 2121, with the middle of the hooks 22 contacting the end of the circuit board 30 closest to the terminal group 20. The hooks 22, in conjunction with the first insulator 40 and the circuit board 30, better limit the conductive terminals 2121, preventing them from becoming loose during insertion and removal. Furthermore, the hooks 22, together with the first insulator 40, insulate and separate the conductive terminals 2121, preventing short circuits.

[0025] Lugs 221 extend from both sides of the hook 22 toward the end of the circuit board 30. The lugs 221 correspond to the two sides of the protrusion 51 of the circuit board 30, and there is a gap between the lugs 221 and the circuit board 30. The lugs 221 are embedded in the second insulator 50, thereby connecting and fixing the hook 22 and the second insulator 50. While fixing the hook 22, it also serves to restrict the first insulator 40 and the second insulator 50. At the same time, the gap between the hook 22 and the circuit board 30 allows the second insulator 50 on both sides of the upper and lower surfaces of the circuit board 30 to be integrally formed during injection molding, which is convenient for processing.

[0026] The second insulator 50 is stepped, and the surface of the second insulator 50 extending out of one side of the housing 10 is at the same level as the surface of the housing 10, thereby ensuring that the surface of the connector remains relatively flat. At the same time, one end of the second insulator 50 can form a structure embedded inside the housing 10, which, together with the protrusion 51, achieves better locking and restriction.

[0027] This utility model provides a connector with a semi-enclosed structure. By setting a second insulator at the welding point of the terminal group and the circuit board, the second insulator wraps around the terminal group circuit board, thereby increasing the connection strength at the welding point. Furthermore, one end of the shell extends to cover the surface of the second insulator, and the protrusions on the second insulator are inserted into the slots of the shell to form a limit, which improves the connection stability between the shell and the second insulator. At the same time, the shell can also be used to reinforce the connection between the second insulator and the first insulator, thereby improving the overall strength of the connector.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
