Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically refers to an automotive lamp holder connector. Background Technology

[0002] Automotive lamp connectors are core interface components of automotive lighting systems, used to connect automotive lamps to the vehicle's electrical circuitry, enabling current and signal transmission, ensuring the lamps function properly, and adapting to vibrations, temperature and humidity changes during vehicle operation to maintain connection stability.

[0003] Existing automotive lamp connectors have significant shortcomings in assembly and maintenance: during assembly, some products lack precise guiding structures, making it difficult to align the terminal block with the housing, and the fixing steps are cumbersome, easily leading to component jamming or terminal misalignment, reducing assembly efficiency; during disassembly, the locking structure is complex, often requiring special tools, and some even require the removal of surrounding components first, which is not only inconvenient to operate, but also easily damages components such as clips and terminals, increasing maintenance difficulty and cost. Therefore, there is an urgent need for an automotive lamp connector structure that can simplify the assembly process and achieve convenient and non-destructive disassembly. Utility Model Content

[0004] This utility model solves the problems mentioned in the background art by providing an installation cavity and a connection cavity in the outer shell, and by using a terminal block with locking claws and guide ribs, along with a reset pad, to achieve precise assembly and press-to-unlock of the terminal block.

[0005] The purpose of this utility model is achieved as follows: an automotive lamp socket connector, including connecting terminals, further includes: The connector housing has a mounting cavity at the top and a connection cavity at the bottom, with the connection terminal extending from the mounting cavity to the connection cavity; A terminal block is disposed in the mounting cavity. The top of the connecting terminal is fixed on the terminal block. The periphery of the terminal block is provided with a plurality of evenly distributed locking claws, and a guide rib is provided between adjacent locking claws. The inner wall of the periphery of the mounting cavity is provided with a locking groove that engages with the locking claws and a guide groove that slides with the guide rib. A reset pad is located at the bottom of the terminal block. When the locking claw engages with the locking groove, the reset pad is compressed between the terminal block and the bottom wall of the mounting cavity.

[0006] The present invention is further configured such that by pressing down on the terminal block to compress the reset pad, the locking claw can disengage from the locking groove, thereby removing the terminal block from the mounting cavity.

[0007] The present invention is further configured such that the guide rib extends from the top edge of the terminal block to the bottom.

[0008] The present invention is further configured such that the resetting pad extends outward to form a positioning flange, and the bottom wall of the mounting cavity is provided with a positioning groove to accommodate the positioning flange.

[0009] The present invention is further provided that the end of the locking claw is provided with a guide slope.

[0010] The present invention is further configured such that the reset pad and the terminal block are integrally formed.

[0011] The present invention is further configured such that the reset pad is made of silicone or thermoplastic elastomer material.

[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By sliding the guide ribs of the terminal block with the guide grooves of the housing mounting cavity, the terminal block is accurately guided along the preset path, which improves assembly efficiency.

[0013] 2. The locking claw engages with the locking slot to secure the parts, and the terminal block is pressed to compress the reset pad to unlock the parts. This makes disassembly tool-free and less likely to damage components, thus improving the ease of maintenance.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 : Example 1: This embodiment provides an automotive lamp holder connector, including a connection terminal 1, and further comprising: The connector housing 2 has a mounting cavity 3 at the top and a connecting cavity 4 at the bottom, and the connecting terminal 1 extends from the mounting cavity 3 to the connecting cavity 4; Terminal base 5 is disposed in the mounting cavity 3. The top of the connecting terminal 1 is fixed on the terminal base 5. The periphery of the terminal base 5 is provided with a plurality of evenly distributed locking claws 6, and a guide rib 7 is provided between adjacent locking claws 6. The periphery of the mounting cavity 3 is provided with a locking groove 8 that engages with the locking claws 6, and a guide groove 9 that slides with the guide rib 7. The reset pad 10 is located at the bottom of the terminal block 5. When the locking claw 6 engages with the locking groove 8, the reset pad 10 is compressed between the terminal block 5 and the bottom wall of the mounting cavity 3.

[0018] The connecting terminal 1 is the core conductive component for transmitting current and signals. It is constructed as a conductive metal strip or needle-like structure, with a shape adapted to the connection requirements of the lamp and the circuit. Its position extends from the mounting cavity 3 of the connector housing 2 to the connecting cavity 4. The top can be fixed to the terminal block 5 by welding, while the bottom is connected to the external circuit or lamp interface inside the connecting cavity 4. Circuit conduction is achieved through physical contact, and its function is to transmit the current and signals of the vehicle body circuit to the automotive lamp.

[0019] The connector housing 2 is a supporting and protective component of the entire device. It is constructed as a robust shell structure, its shape designed according to the installation space, typically cylindrical or box-shaped. Its top has a mounting cavity 3 for mounting the terminal block 5, and its bottom has a connection cavity 4 for connecting to external components. The housing houses the connection terminals 1 and protect them. The connector housing 2 provides a mounting base for internal components through its structure, while simultaneously isolating the internal connections from the external environment. It can be connected to automotive lighting fixtures via a snap-fit ​​mechanism.

[0020] Terminal block 5 is a component that fixes the terminal 1 and assembles it with the connector housing 2. It is constructed as a block shape that fits the mounting cavity 3, and its shape matches the inner wall of the mounting cavity 3. Multiple evenly distributed locking claws 6 and guide ribs 7 located between adjacent locking claws 6 are integrally formed on its periphery. The top is used to fix the top of the terminal 1, and the bottom contacts the reset pad 10. Terminal block 5 is fixed by the locking claws 6 engaging with the locking grooves 8 of the housing mounting cavity 3. The guide ribs 7 slide with the guide grooves 9 to guide the assembly, ensuring the stable position of the terminal 1 and achieving accurate assembly and locking with the connector housing 2.

[0021] The locking claw 6 is a component that locks the terminal block 5 to the connector housing 2. It is constructed as an elastic protrusion extending outward from the periphery of the terminal block 5, with an engaging portion at its end that mates with the locking groove 8. The claws are evenly distributed around the periphery of the terminal block 5 and are integrally formed with it. When the terminal block 5 is inserted into the mounting cavity 3, the locking claw 6 engages with the locking groove 8 on the inner wall of the mounting cavity 3, restricting the axial movement of the terminal block 5. Its function is to fix the terminal block 5 within the mounting cavity 3 and prevent it from falling out.

[0022] The guide rib 7 is a component that guides the assembly direction of the terminal block 5. It is constructed as a strip-shaped structure protruding outwards from the periphery of the terminal block 5, and its shape matches the guide groove 9 of the mounting cavity 3. It is located between adjacent locking claws 6, extending from the top edge of the terminal block 5 to the bottom, and is integrally formed with the terminal block 5. During assembly, the guide rib 7 slides against the guide groove 9 on the inner wall of the mounting cavity 3, its function being to restrict the radial rotation of the terminal block 5 and ensure that it is accurately inserted into the mounting cavity 3 along a predetermined path.

[0023] The reset pad 10 is a component that provides elastic reset force. It is constructed as a flexible plate-like structure, its shape adapted to the bottom of the terminal block 5, and is made of elastic material, allowing it to be integrally molded with the terminal block 5. Its position is at the bottom of the terminal block 5. When the locking claw 6 engages with the locking groove 8, the reset pad 10 is compressed between the terminal block 5 and the bottom wall of the mounting cavity 3. Its function is to provide an upward reset force through elastic deformation. Simultaneously, it can be further compressed when the terminal block 5 is pressed, causing the locking claw 6 to disengage from the locking groove 8. The reset pad 10 continuously provides an upward elastic reset force under compression, which not only helps ensure a tight fit between the locking claw 6 and the locking groove 8, but also absorbs vibration and impact during vehicle operation, eliminates gaps between components, and improves the long-term stability of the connector.

[0024] During assembly, the terminal block 5, with the connecting terminal 1 fixed thereon, is aligned with the mounting cavity 3 of the connector housing 2, aligning the guide ribs 7 on the periphery of the terminal block 5 with the guide grooves 9 on the inner wall of the mounting cavity 3. The terminal block 5 is then pushed downwards into the mounting cavity 3 along the guide grooves 9. During this pushing process, the guide slope 13 at the end of the locking claw 6 contacts the inner wall of the mounting cavity 3, forcing the locking claw 6 to elastically deform and retract inwards. When the terminal block 5 is pushed to the preset position, the locking claw 6 springs into the corresponding locking groove 8 to engage. At this time, the reset pad 10 at the bottom of the terminal block 5 is compressed between the terminal block 5 and the bottom wall of the mounting cavity 3, generating an upward elastic reset force that presses the locking claw 6 tightly into the locking groove 8, ensuring a stable connection. The connecting terminal 1 extends from the mounting cavity 3 to the connecting cavity 4, connecting the lamp to the circuit. When disassembly is required, the terminal block 5 is pressed downwards to further compress the reset pad 10, causing the locking claw 6 to move downwards with the terminal block 5 and disengage from the locking groove 8. At this point, the terminal block 5 can be removed from the mounting cavity 3, completing the disassembly.

[0025] By pressing down on the terminal block 5 to compress the reset pad 10, the locking claw 6 can disengage from the locking groove 8, allowing the terminal block 5 to be removed from the mounting cavity 3. This design aims to provide a convenient and damage-free method for disassembling the terminal block 5, ensuring smooth removal from the mounting cavity 3 during subsequent maintenance or replacement. Pressing down on the terminal block 5 directly applies pressure to the reset pad 10 at its bottom, causing compression deformation and moving the terminal block 5 downwards. This process allows the locking claw 6, which was originally engaged with the locking groove 8, to move downwards simultaneously, disengaging from the groove. At this point, no special tools or removal of surrounding components are required; the terminal block 5 can be directly removed from the mounting cavity 3. This avoids damage to the locking claw 6, terminals, or inner wall of the housing due to complex disassembly operations, while simplifying the disassembly process and ensuring the entire connector structure maintains normal operation even after multiple disassemblies.

[0026] The guide rib 7 extends from the top edge of the terminal block 5 to the bottom. The purpose of this design is to allow the guide rib 7 to play a guiding role throughout the assembly process of the terminal block 5, ensuring that the terminal block 5 is stably installed into the mounting cavity 3. The guide rib 7 extends from the top edge of the terminal block 5 to the bottom, ensuring that the guide rib 7 maintains a sliding fit with the guide groove 9 on the inner wall of the mounting cavity 3 throughout the entire process from the initial insertion of the terminal block 5 into the mounting cavity 3 to its final engagement with the locking groove 8. This prevents the terminal block 5 from radially shifting or rotating due to insufficient coverage of the guiding structure during installation. This extension method provides continuous directional constraint for the terminal block 5, allowing it to move smoothly down a preset path. Simultaneously, it ensures that the locking claws 6 on the periphery of the terminal block 5 are always aligned with the locking groove 8 of the mounting cavity 3, preventing the locking claws 6 from failing to accurately engage with the locking groove 8 due to terminal block 5 misalignment, thus ensuring the smoothness of the assembly process and the stability of the final assembly state.

[0027] The reset pad 10 extends outward from its periphery to form a positioning flange 11, and the bottom wall of the mounting cavity 3 is provided with a positioning groove 12 to accommodate the positioning flange 11. The purpose of this design is to limit the positional displacement of the reset pad 10 during use by cooperating with the positioning flange 11 and the positioning groove 12, thus ensuring the stable functioning of the reset pad 10. The positioning flange 11 is constructed as an annular or segmented edge structure extending outward from the periphery of the reset pad 10, and the positioning groove 12 is constructed as an annular or segmented groove on the bottom wall of the mounting cavity 3 that is complementary in shape to the positioning flange 11. In terms of connection, when the reset pad 10 is assembled, its peripheral positioning flange 11 will be correspondingly embedded in the positioning groove 12 on the bottom wall of the mounting cavity 3, forming a physical limit. This fit prevents the reset pad 10 from sliding radially or rotating circumferentially during compression or reset, ensuring that the reset pad 10 is always in the preset position between the bottom of the terminal block 5 and the bottom wall of the mounting cavity 3. This avoids uneven force on the terminal block 5, misalignment between the locking claw 6 and the locking groove 8, or the reset pad 10 failing to provide stable elastic reset force due to the offset of the reset pad 10, thus maintaining the assembly stability of the entire connection structure.

[0028] The locking claw 6 has a guide slope 13 at its end. This design aims to reduce the operational resistance when the terminal block 5 is inserted into the mounting cavity 3, ensuring that the locking claw 6 can smoothly engage with the locking groove 8. The guide slope 13 is constructed as an inclined surface structure that smoothly transitions from the end of the locking claw 6 to its root. When the terminal block 5 is inserted downwards into the mounting cavity 3, the guide slope 13 will first contact the inner wall of the mounting cavity 3. As the terminal block 5 continues to move downwards, the force exerted by the inner wall of the mounting cavity 3 on the guide slope 13 will be decomposed along the slope direction, pushing the locking claw 6 to elastically deform towards the inside of the terminal block 5, allowing the locking claw 6 to smoothly overcome the obstruction of the inner wall of the mounting cavity 3. Once the terminal block 5 has moved to the preset position, the locking claw 6 will reset under its own elastic action and engage with the locking groove 8, avoiding jamming during insertion due to the lack of a guide structure at the end of the locking claw 6, ensuring the smoothness of the terminal block 5 assembly process, and reducing wear on the locking claw 6 or the inner wall of the mounting cavity 3.

[0029] The reset pad 10 and the terminal block 5 are integrally formed. This design simplifies the assembly process of the reset pad 10 and the terminal block 5, while enhancing the stability of their connection and preventing separation or misalignment during use. The reset pad 10 and the terminal block 5 are formed in a single molding process, creating an inseparable integral structure, eliminating the need to separately install the reset pad 10 onto the bottom of the terminal block 5 during subsequent assembly. This eliminates the assembly gap between the reset pad 10 and the terminal block 5, ensuring that the reset pad 10 always precisely corresponds to the preset position on the bottom of the terminal block 5. This prevents the reset pad 10 from shifting or falling off due to vibrations during vehicle operation or repeated disassembly and pressing, thus ensuring that the reset pad 10 can be evenly stressed and stably provide elastic reset force during compression, maintaining a reliable fit between the locking claw 6 and the locking groove 8. Simultaneously, it reduces the number of parts and lowers the complexity of production and assembly processes.

[0030] The reset pad 10 is made of silicone or thermoplastic elastomer. This design aims to ensure that the reset pad 10 can stably perform its elastic reset and buffering functions, while adapting to the complex operating conditions during automotive use. Silicone and thermoplastic elastomer materials inherently possess good elastic deformation capabilities. When compressed during terminal block assembly 5, they continuously generate an upward reset force, ensuring that the locking claw 6 tightly fits the locking groove 8, maintaining the fixed state of the terminal block 5. When the terminal block 5 needs to be disassembled, these materials can further contract with the pressure applied to the terminal block 5 and return to their original shape after the pressure is released, ensuring the stability of the function during subsequent repeated use. Furthermore, these two materials also possess certain temperature resistance, aging resistance, and vibration resistance properties, enabling them to withstand temperature changes and vibration impacts during vehicle operation. This prevents the reset pad 10 from losing elasticity or being damaged due to material failure, thus maintaining its support and reset effect on the terminal block 5 for a long time and ensuring the stable operation of the entire connector structure.

[0031] During assembly in this embodiment, the terminal block 5 with the fixed connecting terminal 1 is aligned with the mounting cavity 3 on the top of the connector housing 2, so that the guide rib 7 between the adjacent locking claws 6 on the periphery of the terminal block 5 is aligned with the guide groove 9 on the inner wall of the periphery of the mounting cavity 3, and then the terminal block 5 is pushed down into the mounting cavity 3 along the guide groove 9. During the insertion process, the guide slope 13 at the end of the locking claw 6 contacts the inner wall of the mounting cavity 3, forcing the locking claw 6 to undergo elastic deformation and retract inward. When the terminal block 5 moves down to the preset position, the locking claw 6 elastically resets and engages with the corresponding locking groove 8 on the inner wall of the mounting cavity 3. At this time, the reset pad 10, made of silicone or thermoplastic elastomer material, is compressed between the terminal block 5 and the bottom wall of the mounting cavity 3. The reset pad 10 can be integrally formed with the terminal block 5, and its peripheral positioning flange 11 is embedded in the positioning groove 12 on the bottom wall of the mounting cavity 3. The reset pad 10 generates an upward elastic reset force to press the locking claw 6 tightly into the locking groove 8. At the same time, the connecting terminal 1 extends from the mounting cavity 3 to the connecting cavity 4 at the bottom of the housing, realizing the connection with the external circuit or lamp. When it is necessary to remove the terminal block 5, press the terminal block 5 down to further compress the reset pad 10, drive the terminal block 5 down and let the locking claw 6 disengage from the locking groove 8, and then take out the terminal block 5 upward along the guide groove 9 to complete the removal.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
