Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a side-mounted locking tongue connector. Background Technology

[0002] In the field of connector technology, with the continuous development and widespread application of electronic devices, connectors, as key components for realizing circuit connections and signal transmission, are crucial to the normal operation of equipment due to their performance and reliability.

[0003] Connector housings typically have a mating cavity, into which terminals are inserted. Wires are connected to the ends of the terminals. During normal use, the wires are pulled, which causes the terminals to move within the mating cavity. When an outward pulling force is applied to the terminals, they can easily detach from the connector housing, causing the connector to disconnect and fail. Summary of the Invention

[0004] To reduce the risk of terminals detaching from the connector housing, a side-mounted locking tongue connector is provided.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A side-mounted latch connector includes a housing with a receiving groove inside the housing. A terminal block is inserted into the receiving groove. The terminal block includes a conductive piece and a connecting piece. A limiting space is provided between the conductive piece and the connecting piece. The housing also has a plug interface communicating with the receiving groove. The connector also includes a latch, which includes a limiting member inserted into the plug interface. The limiting member is inserted into the limiting space and abuts against the inner wall of the plug interface.

[0007] By adopting the above technical solution, during installation, the limiting member is inserted into the connector and located in the limiting space, which can restrict the slotting direction of the terminal block in the receiving groove. When the wire applies an outward pulling force to the terminal block, the force will be transmitted to the housing through the limiting member, effectively restricting the movement of the terminal block in the receiving groove, preventing the terminal block from detaching from the housing due to the wire pulling force, enhancing the reliability of the connection between the connector and the terminal block, and ensuring that the connector can normally realize the circuit connection and signal transmission functions.

[0008] Preferably, one side of the insertion interface is connected to the outside, and the other side of the insertion interface is connected to the receiving groove. The limiting member is located inside the insertion interface. One side of the limiting member is provided with a sliding part that passes through the insertion interface. Limiting protrusions are fixed on the two inner walls of the insertion interface facing the sliding part, respectively.

[0009] By adopting the above technical solution, the bidirectional connection design of the plug interface facilitates the insertion and operation of the limiting component. The two limiting protrusions guide and limit the sliding part in the sliding direction, ensuring that the limiting component is stably inserted into the plug interface. At the same time, the limiting protrusions can also restrict the position of the limiting component, so that it can only be inserted and removed along the opening direction of the plug interface, thereby enhancing the stability of the limiting component in restricting the terminal block.

[0010] Preferably, the limiting member includes a limiting part inserted into the limiting space, the limiting part having a flat surface on the side facing the connecting piece, and the limiting part having an inclined surface on the side facing the conductive piece.

[0011] By adopting the above technical solution, the connecting piece is usually in a vertical state in actual use, and the limiting part facing the connecting piece is set as a plane, which can better abut against the connecting piece; the conductive piece needs to bind the wire in actual use, and the limiting part facing the conductive piece is set as an inclined surface, which can better limit and press the conductive piece, further improving the stability of the terminal block in the housing.

[0012] Preferably, the limiting member includes an insertion end and an operating end, wherein the outer wall of the operating end is flush with the outer wall of the housing.

[0013] By adopting the above technical solution, the operating end is flush with the outer wall of the housing. During connector installation, the operating end can be prevented from protruding from the housing and causing bumps or affecting the installation of other components. It is suitable for installation in compact spaces and expands the application scenarios of the connector. Furthermore, after the connector is installed, other components can press against and limit the operating end, making the limiting component more stable inside the connector.

[0014] Preferably, a guide slope is provided between the end of the insertion end and the outer wall of the limiting member.

[0015] By adopting the above technical solution, when the locking tongue limiter is inserted into the insertion interface and the limiting space, the guide slope can play a guiding role, reduce the frictional resistance when the limiter is inserted, make the limiter insert more smoothly, avoid jamming or difficulty in insertion during the insertion process, and improve installation efficiency and convenience.

[0016] Preferably, the locking tongue further includes a locking member integrally formed with the locking end, the locking member extending along the opening direction of the insertion interface, a locking block fixed at the end of the locking member, a locking groove for the locking block to slide into the housing, and the locking block abutting against the inner wall of the locking groove.

[0017] By adopting the above technical solution, the locking block at the end of the locking member slides into the locking groove in the housing and abuts against the inner wall, further enhancing the connection stability between the locking tongue and the housing and preventing the locking tongue from retracting. Compared with the friction fixation of the limiting member and the insertion interface alone, the mechanical snap-fit ​​structure of the locking block and the locking groove provides stronger anti-pull-out capability. In a vibration environment, it can prevent the locking tongue from loosening or the terminal from falling off due to mechanical vibration, ensuring the long-term stability of the connector under vibration or external force.

[0018] Preferably, the locking member is fixed with a limiting protrusion on the side facing the housing, and the outer wall of the housing is provided with two opposing limiting slides, with the limiting protrusion embedded between the two limiting slides.

[0019] By adopting the above technical solution, the limiting slide rail constrains the limiting protrusion, which can limit the locking part and restrict the offset of the locking part in the insertion and removal direction of the terminal block. At the same time, the locking block restricts the retraction of the locking part in the insertion direction of the locking tongue, forming a multi-dimensional fixing effect and improving the reliability of the connector in different scenarios.

[0020] Preferably, the locking block is trapezoidal, and a guide block is fixedly provided on the outer wall of the housing. The guide block has a guide surface on the side facing the sliding direction of the locking member, and the side of the locking block with the inclined surface slides against the guide surface along the sliding direction of the locking member.

[0021] By adopting the above technical solution, the design of the inclined surface and the guide surface can guide the locking block to slide smoothly, ensuring that the locking block slides accurately into the locking groove in the housing, enhancing the stability and reliability of the connection between the lock tongue and the housing, and further preventing the wiring terminal from detaching from the housing.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The locking tongue is inserted into the limiting space of the terminal block. The sliding part is integrally formed with the limiting part and abuts against the inner wall of the plug interface to form a mechanical block. When the wire is pulled out, the force is transmitted to the housing through the limiting part, which effectively prevents the terminal from falling off and greatly improves the connection stability.

[0024] 2. The locking block of the locking component is embedded in the locking groove of the housing to form a mechanical snap-fit ​​structure, which further enhances the anti-pull-out capability of the locking tongue in the insertion and extraction direction, and is suitable for application scenarios with large vibration or external force.

[0025] 3. The limiting protrusion is embedded between the two limiting slides to limit the offset of the locking component in the insertion and removal direction of the terminal block. Combined with the mechanical fixation of the locking block, it forms a multi-dimensional constraint to ensure that the locking tongue can remain stable under complex working conditions.

[0032] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0033] As attached Figure 1 As shown, a side-mounted latch connector includes a housing 1, a terminal block 2 and a latch 3. The housing 1 has a receiving groove 11 for the terminal block 2 to be inserted into. There are two receiving grooves 11, and two terminal blocks 2 are inserted into the two receiving grooves 11 respectively.

[0034] The terminal block 2 includes an integrally formed connecting piece 21, a conductive piece 22, and a wire harness 23. There are two conductive pieces 22, which are arranged opposite each other and are used to realize the conductivity function of the circuit. There are two wire harnesses 23, which are arranged opposite each other. A limiting space 24 is provided between the conductive piece 22 and the connecting piece 21. The wires pass through the two wire harnesses 23 and the two conductive pieces 22 respectively and are located at the connecting piece 21. The two wire harnesses 23 are pressed against each other to bind the rubber part of the wires. The two conductive pieces 22 are pressed against each other to bind the wire part in the wires.

[0035] As attached Figure 2As shown, the housing 1 has an insertion interface 12 along the slotting direction perpendicular to the receiving groove 11. One side of the insertion interface 12 is connected to the receiving groove 11, and the other side of the insertion interface 12 is connected to the outside. The locking tongue 3 includes a limiting member 31 inserted into the insertion interface 12. The limiting member 31 is located inside the insertion interface 12 and above the terminal 2. The side of the limiting member 31 facing away from the terminal 2 has a sliding part 311 that passes through the insertion interface 12. The two inner walls of the insertion interface 12 facing the sliding part 311 are integrally formed with limiting flanges 13. The two limiting flanges 13 can guide and limit the sliding part 311 in the sliding direction. The limiting flanges 13 restrict the position of the limiting member 31 in the insertion interface 12 and restrict the movement of the limiting member 31 in the direction perpendicular to the insertion direction, ensuring that the limiting member 31 can only be inserted and removed along the opening direction of the insertion interface 12.

[0036] The limiting member 31 also includes a limiting part 312 inserted into the limiting space 24. The limiting part 312 is flat on the side facing the connecting piece 21, and has a bevel on the side facing the conductive piece 22. The bevel design facilitates the insertion of the limiting part 312 into the limiting space 24 and serves as a guide. The connecting piece 21 does not need to be bent in actual use. The flat side of the limiting part 312 facing the connecting piece 21 can better abut against the connecting piece 21, increasing the limiting area of ​​the limiting part 312 on the terminal 2. The conductive piece 22 needs to bind the wire part in the conductor in actual use. The bevel on the side of the limiting part 312 facing the conductive piece 22 can better limit and press the conductive piece 22, further improving the stability of the terminal 2 in the housing 1.

[0037] As attached Figure 2 and attached Figure 3 As shown, the limiting member 31 also includes an operating end 313 and an insertion end 314. The outer wall of the operating end 313 is flush with the outer wall of the housing 1. When the connector is installed, the operating end 313 can be prevented from protruding from the housing 1 and causing bumps or affecting the installation of other components. It is suitable for installation in compact spaces. Furthermore, other components can press against the limiting operating end 313 without the need to use other tools to limit and fix it, which improves convenience.

[0038] The insertion end 314 is inserted into the insertion interface 12 along the opening direction of the insertion interface 12. A guide slope 315 is provided between the end of the insertion interface 12 and the outer wall of the limiting member 31. The guide slope 315 can play a guiding role, avoiding jamming or difficulty in insertion during the insertion process, and improving installation efficiency and convenience.

[0039] As attached Figure 3 and attached Figure 4As shown, the latch 3 also includes a locking member 32 integrally formed with the operating end 313. The locking member 32 is located outside the housing 1 and is flush with the outer wall of the housing 1. One end of the locking member 32 is flush with the operating end 313, and the other end of the locking member 32 is opposite to the limiting member 31. The locking member 32 extends along the opening direction of the insertion interface 12. A locking block 321 is fixed at the end of the locking member 32. The locking block 321 is trapezoidal in shape. The side of the locking block 321 with a flat surface faces the operating end 313, and the side of the locking block 321 with a bevel faces away from the locking end. A locking groove 14 is opened in the housing 1 for the locking block 321 to slide into. The side of the locking block 321 with a flat surface abuts against the inner wall of the locking groove 14, further enhancing the connection stability between the latch 3 and the housing 1 and preventing the latch 3 from retracting.

[0040] A guide block 15 is fixedly provided on the outer wall of the housing 1 facing the locking member 32. The guide block 15 has an inclined guide surface 151 on the side facing the operating end 313 and a flat surface on the side facing away from the operating end 313. The side of the guide block 15 facing away from the operating end 313 is flush with the inner wall of the locking groove 14. The guide block 15 is integrally formed with the outer wall of the housing 1. The side of the locking block 321 with the inclined surface slides against the guide surface 151 along the sliding direction of the locking member 32. The design of the guide block 15 and the guide surface 151 facilitates the smooth sliding of the locking block 321 into the locking groove 14, ensuring that the locking block 321 is accurately slidably embedded into the locking groove 14 in the housing 1.

[0041] As attached Figure 4 and attached Figure 5 As shown, two limiting slides 16 are fixedly provided on the outer wall of the housing 1 at the end where the locking member 32 is connected to the operating end 313. The two limiting slides 16 are arranged opposite to each other, and the locking member 32 is fixedly provided with a limiting protrusion 322 on the side of the operating end 313 facing the housing 1. The limiting protrusion 322 is located at the connection between the operating end 313 and the locking member 32. The limiting protrusion 322 is snapped into the two limiting slides 16. The limiting slides 16 constrain the limiting protrusion 322, which can limit the locking member 32 and restrict the offset of the locking member 32 in the insertion and removal direction of the terminal 2. At the same time, the locking block 321 restricts the retraction of the locking member 32 in the insertion direction of the locking tongue 3, forming a multi-dimensional fixing effect.

[0042] The implementation principle of this embodiment:

[0043] The terminal 2 is inserted into the receiving groove 11 of the housing 1. The limiting space 24 formed between the conductive piece 22 and the connecting piece 21 provides an insertion position for the limiting part 312 of the locking tongue 3. The limiting part 312 is inserted through the insertion interface 12 of the housing 1. The plane of the limiting part 312 abuts against the connecting piece 21, and the inclined surface abuts against the conductive piece 22. When the wire is pulled outward, the force is transmitted to the limiting member 31 through the terminal 2, and then transmitted from the limiting member 31 to the inner wall of the insertion interface 12 and the limiting protrusion 13 of the housing 1. Since the limiting member 31 is tightly abutted against the inner wall of the insertion interface 12, the pulling force is absorbed by the housing 1, thereby preventing the terminal from coming off.

[0044] The locking member 32 is integrally formed with the operating end 313. The trapezoidal locking block 321 at its end slides along the guide surface 151 of the guide block 15 and finally embeds into the locking groove 14 of the housing 1, further restricting the offset of the locking member 32 in the insertion and removal direction, forming a multi-dimensional fixing effect, effectively resisting vibration or external force, and ensuring that the connector works stably for a long time in complex environments.

[0045] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
