[0002] With the rapid development of new energy vehicle technology and the increasing level of automotive electronics, the requirements for electronic devices in automobiles are becoming increasingly stringent. Automotive components are evolving towards higher precision, higher sensitivity, and higher efficiency, while also demanding ease of installation and removal in automotive factories. In the use of touch sensors on automotive doors, connectors must not only ensure high efficiency and sensitivity but also withstand various harsh environments to guarantee stable signal and power transmission. Therefore, developing a high-precision, high-sensitivity, lightweight connector for automotive door touch sensors that is waterproof, provides stable current conduction, and is easy and quick to install has become particularly important.

[0003] Most existing connector technologies use a press-to-disassemble interface for connector removal. However, connector manufacturers using this method often fail to consider the difficulties in handling the connector during removal, and how different handling techniques can cause structural deformation. This leads to difficulties in assembly, incorrect assembly, and ultimately, faulty terminal contact, resulting in circuit failure. Existing technologies also feature symmetrical terminal hole designs, neglecting ease and efficiency in manufacturing, thus increasing production costs. Furthermore, existing waterproof structures are complex, with the waterproof ring's shape largely conforming to the main body's outline, lengthening design time and increasing product weight, thus lacking portability.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] Please see Figure 1 The embodiments of this utility model include: This utility model discloses a waterproof female connector for an external touch sensor on an automotive door, comprising a housing 1, an inner core 2, and a locking slider 3. The housing 1 has a terminal block 11 at its upper end and a mounting hole at its lower end, with an internal mounting cavity for assembly with the inner core 2. A sealing assembly 4 is installed between the inner core 2 and the mounting cavity. A plug-in portion 5 is provided on the outside of the housing 1. The locking slider 3 is engaged or disengaged from the plug-in portion 5 via a positioning assembly 6. The overall structure of this application is designed with a symmetrical distribution, reducing mold design and processing costs, facilitating production clamping, and simplifying packaging.

[0019] The insertion part 5 includes a slot 51 formed by a flat inner wall, an outer arc wall 53, a left side wall, and a right side wall on an outer side wall of the outer shell. The outer arc wall 53 has a vertically arranged starting positioning hole 52 and a stopping positioning hole 57. The unlocking slide 3 is provided with a positioning spring 31. When the unlocking slide 3 is inserted into the slot 51, the positioning spring 31 engages with either the starting positioning hole 52 or the stopping positioning hole 57. In a specific embodiment of this application, the positioning spring is a hemispherical design, which facilitates slide displacement and positioning during pressing.

[0020] Positioning grooves 54 are correspondingly provided on the left and right walls, and positioning blocks 32 are provided on both sides of the unlocking slide 3. When the unlocking slide 3 is inserted into the slot 51, the positioning blocks 32 are engaged in the positioning grooves 54. Specifically, the positioning blocks are wedge-shaped blocks, with the upper surface of the wedge-shaped blocks abutting against the upper edge of the positioning groove. The unlocking slide, in cooperation with the positioning groove, forms an elastic clamping structure. After the unlocking slide is installed in the positioning groove, the elastic clamping feature generates a force in the opposite direction, thereby preventing the unlocking slide from disengaging during the assembly process. This improves upon the existing technology's use of press-fit spring clips for unlocking, which causes component deformation, and facilitates mold processing and injection molding, reducing manufacturing costs.

[0021] Specifically, the unlocking slide 3 includes an insert plate 33 and a baffle 34 perpendicularly connected thereto. The insert plate 33 is arc-shaped and matches the outer arc wall 53. The positioning block 32 is disposed on both sides of the insert plate 33.

[0022] The sealing assembly 4 includes a sealing ring 41 and a sealing gasket 42. The sealing gasket 42 is installed between the terminal block 11 at the upper end of the inner core 2 and the upper end of the outer shell 1. The inner core 2 is provided with an assembly groove, and the sealing ring 41 is installed on the assembly groove for pressing against the inner wall of the assembly groove.

[0023] Specifically, the sealing ring is circular, and the inner core's mounting groove is square. After assembly, the waterproof ring will be squeezed into a square structure similar to the inner core structure. This design is mainly to save on design and manufacturing costs while ensuring functionality.

[0024] The outer arc wall 53 and the flat inner wall extend outward to form an outer spring piece 57 and an inner spring piece 55. A corresponding latch 56 is provided on the outer spring piece and the inner spring piece for mating with the male connector during assembly. The cavity design of the female connector housing, with its matching latching spring, ensures that the internal surfaces of the cavity contact and lock together when the male and female connectors mate, thus preventing the connector from easily loosening during assembly.

[0025] Both the terminal holes on the terminal block of the outer shell 1 and the terminal holes on the inner core 2 are provided with four terminals each, with two terminals arranged in a row. The two rows are staggered to form an oblique symmetrical structure. This design reduces the insertion force when the connectors are mated, and the asymmetrical design of the terminal holes disperses stress concentration.

[0026] The inner wall of the mounting cavity of the outer shell 1 is provided with an anti-misalignment and stop groove 12, and the inner core 2 is correspondingly provided with an anti-misalignment and stop block 21. The anti-misalignment and stop block 21 and the anti-misalignment and stop groove 12 are matched and installed. This can prevent the parts from deforming due to misassembly during the assembly of the inner core, and also make the inner core more firmly fixed in the outer shell cavity after assembly.

[0027] The end of the terminal hole of the inner core 2 is provided with a guide structure 22, and the inner wall of the terminal hole of the inner core 2 is provided with a terminal spring tongue structure (23) for locking and releasing the terminal pin. The guide structure provided at the end of the terminal hole in this application reduces the insertion force of the terminal relative to the connector; the terminal spring tongue structure in this application is an elastic component, which is inserted into the structure with a special tool, and after the stop is released, the terminal pin can be withdrawn from the connector.

[0028] The inner core 2 is also provided with a locking member 25 that cooperates with the terminal secondary lock. The locking member 25 is fixed in a pre-locked position on the inner core, and the terminal secondary lock function is realized by the locking position.

[0029] The two sides of the upper end face of the outer shell 1 are symmetrically connected to form a disassembly plate. An I-shaped structure 13 is installed on the lower end face of the disassembly plate. The I-shaped structure 13 includes a fixing component 131 with a triangular lower end face of the disassembly plate. An arch bridge component 132 is provided at the lower end of the hypotenuse of the fixing component 131, and a gap is provided between the arch bridge component 132 and the outer wall of the outer shell. The I-shaped structure designed in this application is used to fix the wire. After the wire is installed, it can be wrapped and fixed with cable ties, thereby fixing the wire and ensuring sufficient stability during vehicle movement, preventing swaying and ensuring stable electrical contact.

[0030] The outer wall of the sealing gasket 42 is provided with an inverted C-shaped groove (421). When assembled into the inner cavity of the outer shell, it achieves a waterproof function. This design, with its inverted C-shaped groove, increases elasticity under compression and reduces product weight.

[0031] The outer wall of the inner core is also provided with a mis-proof structure 24. The mis-proof structure 24 is an irregular shape that is concave inward. It is used for the mis-proof design of mating with the male connector, and plays a guiding role to ensure the smooth engagement of the male connector and the female connector.

[0032] The end where the inner core and outer shell are installed together has a hollowed-out design 26, which optimizes the product structure and reduces the product's weight.

[0033] The dimensions of this utility model are 26.5x17x17mm (length x width x height), which saves approximately 30% of space and 15% of weight compared to existing designs.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
