Description

Technical Field

[0001] This utility model belongs to the field of electrical connection technology, and in particular relates to a slot-type connector. Background Technology

[0002] Multi-pin connectors, as high-precision electrical interconnect components, typically consist of multiple metric metal pins arranged in a specific pattern and embedded in an insulating base. Circuit conduction is achieved through the mating of these pins with female sockets. These connectors are widely used in electronic equipment, industrial control devices, and precision instruments, and are particularly suitable for miniaturized, complex circuit systems requiring stable transmission of multiple signals or power, such as automotive electronic modules, internal components of medical devices, and communication equipment interfaces. Their core function is to simplify equipment assembly processes through standardized mating structures while ensuring the reliability and consistency of multi-channel connections.

[0003] In existing technologies, the production of multi-pin connectors requires manually soldering each individual pin to a wire, a cumbersome process prone to fluctuations due to manual operation. Because the pins are small and densely packed, uneven heat conduction or deviations in solder quantity control during soldering can lead to issues such as cold solder joints and poor solder joints, directly affecting contact resistance stability and signal transmission quality. Furthermore, the first solder joint formed by traditional soldering processes may experience fatigue fracture under long-term mechanical vibration or temperature cycling, increasing the risk of connection failure. Simultaneously, if the assembly precision and mating tolerances between the pins and the base are not strictly controlled, it may cause accelerated wear on the contact surfaces during insertion and removal, further reducing the connector's durability and environmental adaptability.

[0034] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-6 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0035] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0038] In one embodiment of this utility model, such as Figures 1-6 As shown, a slot-type connector is provided, including a male connector 100 and a female connector 200. The male connector 100 is provided with a plug-in board 300. The female connector 200 is provided with a plug-in female groove 400 for snapping into and adapting to the plug-in board 300. Each end of the plug-in board is provided with a first solder point 600. The plug-in female groove 400 is provided with an elastic pin 500 that can abut against the first solder point 600. The female connector 200 is provided with a flexible board 700. The middle position of the flexible board 700 is electrically connected to the elastic pin 500. The two ends of the flexible board 700 are provided with second solder points.

[0039] Specifically, the snap-fit ​​between the plug-in board 300 and the plug-in female slot 400 replaces the traditional point-by-point welding of multiple pins and wires. The first solder joints 600 at both ends enable multi-channel integrated conductivity to be completed in a single welding process, greatly simplifying the assembly process and eliminating the quality fluctuations of manual welding. The elastic contact between the elastic pin 500 and the first solder joint 600 compensates for the plug-in fit tolerance, avoids wear on the contact surface and maintains stable low impedance conduction. At the same time, the flexible board 700 absorbs mechanical vibration and thermal expansion and contraction stress through elastic deformation, disperses the stress on the solder joint to suppress fatigue fracture, and significantly improves the reliability and plug-in life of the connector under complex working conditions.

[0040] like Figures 1-6As shown, in another embodiment of this utility model, the male connector 100 includes a first guide sleeve 110, a first connecting sleeve 120, and a first limiting seat 130. The first limiting seat 130 is disposed at the inner end of the first connecting sleeve 120, and the first limiting seat 130 is provided with a first limiting groove 131 for limiting the installation of the plug-in circuit board 300. The first guide sleeve 110 is fixedly disposed at the end of the first connecting sleeve 120 away from the female connector 200. The wire passes through the first guide sleeve 110 and is electrically soldered to the first solder joint 600. Through the limiting cooperation between the first limiting groove 131 and the plug-in circuit board 300, the precise positioning of the plug-in circuit board 300 within the male connector 100 is ensured, avoiding the arrangement deviation caused by manual assembly of traditional needles. The first guide sleeve 110 provides radial constraint on the wire, simplifying the soldering operation and preventing the bending stress of the wire from being transmitted to the first solder joint 600, improving the soldering reliability, and eliminating the risk of wire entanglement when soldering multiple needles independently in traditional methods.

[0041] like Figures 1-6 As shown, in another embodiment of this utility model, the first connecting sleeve 120 includes a first locking part 121 and a first snap-fit ​​part 122. The first snap-fit ​​part 122 and the first locking part 121 are coaxially formed sequentially along a straight line. The circumferential sidewall of the first snap-fit ​​part 122 is provided with a snap-fit ​​hole 123. The axial edge of the first limiting seat 130 is provided with a snap-fit ​​block 132 that is adapted to the snap-fit ​​hole 123. The first limiting groove 131 is formed in the middle position of the first limiting seat 130. The integral molding design of the first locking part 121 and the first snap-fit ​​part 122 realizes the rapid assembly of the internal components of the male connector 100. The cooperation between the snap-fit ​​block 132 and the snap-fit ​​hole 123 ensures the stable connection between the first limiting seat 130 and the first connecting sleeve 120, avoiding the loosening problem caused by the traditional connector due to threaded locking or glue fixing method, and further reducing the displacement risk of the plug-in board 300 during the insertion and removal process.

[0042] like Figures 1-6As shown, in another embodiment of this utility model, the connecting female head 200 includes a second guide sleeve 210, a second connecting sleeve 220, and a second limiting seat 230. The second limiting seat 230 is disposed inside the second connecting sleeve 220. The insertion female groove 400 is formed on the second limiting seat 230. The flexible electrical board 700 is disposed at the end of the second limiting seat 230 away from the insertion female groove 400. The elastic pin 500 is mounted on the second limiting seat 230, and the end of the elastic pin 500 extends to the end of the insertion female groove 400. The second guide sleeve 210 and the second connecting sleeve 220 are coaxially formed sequentially along a straight direction. The wire passes through the second guide sleeve 210 and is electrically welded to the second solder joint. The second limiting seat 230 integrates the mounting positions of the plug-in female groove 400 and the flexible pin 500, ensuring the precise alignment of the flexible pin 500 and the plug-in board 300. The second guide sleeve 210 guides the wire to the second solder joint of the flexible board 700, avoiding the complexity of independent soldering of multiple contacts on the female end of the traditional connector. The layout design of the flexible board 700 concentrates the solder joints at both ends, reducing the solder joint density and reducing the superposition of heat-affected zones, thereby suppressing welding defects.

[0043] like Figures 1-6 As shown, in another embodiment of this utility model, the second limiting seat 230 includes a fixing seat 231 and a snap-fit ​​seat 232. The snap-fit ​​seat 232 is snap-fitted into the second connecting sleeve 220. The second connecting sleeve 220 is provided with a snap-fit ​​rib 233. A snap-fit ​​protrusion 234 is provided on the snap-fit ​​rib 233. A snap-fit ​​ring 236 is provided protruding from the circumferential edge of the snap-fit ​​seat 232. A slot 237 for snap-fitting and adapting to the snap-fit ​​protrusion 234 is provided on the snap-fit ​​ring. The snap-fit ​​socket 232 achieves modular installation through the snap-fit ​​engagement of the snap-fit ​​ring and the snap-fit ​​protrusion 234, which facilitates the pre-installation and debugging of the elastic pin 500 and the flexible circuit board 700. Compared with the traditional connector female head integral injection molding or welding process, it significantly improves maintenance convenience. The pressing design of the snap-fit ​​protrusion 233 and the snap-fit ​​socket 232 enhances the anti-torsion ability of the second limit seat 230 during the insertion and removal process, and prevents the elastic pin 500 from contact failure due to uneven force.

[0044] like Figures 1-6As shown, in another embodiment of this utility model, both the fixing base 231 and the snap-fit ​​base 232 are provided with pin mounting grooves 235. The plug-in female groove 400 is formed on the snap-fit ​​base 232. The pin mounting groove 235 communicates with the plug-in female groove 400. The elastic pin 500 is disposed in the pin mounting groove 235, and the elastic deformation portion of the elastic pin 500 extends into the plug-in female groove 400. The pin mounting groove 235 provides directional support for the elastic pin 500, constraining its deformation direction to ensure stable contact with the plug-in circuit board 300. The elastic deformation portion extends into the plug-in female groove 400 to form a pre-compression contact, compensating for plug-in fit tolerances and avoiding the problem of increased conduction resistance caused by insertion and removal wear in traditional rigid contacts.

[0045] like Figures 1-6 As shown, in another embodiment of this utility model, the fixing seat 231 is interference-fitted with the inner ring of the second connecting sleeve 220. The fixing seat 231 and the snap-fit ​​seat 232 are arranged sequentially along the length direction of the inner ring of the second connecting sleeve 220. The snap-fit ​​rib 233 is formed on the inner wall of the inner ring of the second connecting sleeve 220. After the snap-fit ​​seat 232 and the snap-fit ​​protrusion 234 are engaged and matched, the fixing seat 231 is tightly connected in the inner ring of the second connecting sleeve 220 and the snap-fit ​​seat 232 is pressed against the snap-fit ​​rib 233. The interference fit between the fixing seat 231 and the second connecting sleeve 220 forms an axial preload. Combined with the snap-fit ​​locking of the snap-fit ​​seat 232 and the snap-fit ​​protrusion 234, the second limiting seat 230 is double-fixed, effectively suppressing the fretting wear of the internal components of the connecting female head 200 under vibration conditions, and overcoming the risk of loosening caused by long-term insertion and removal of the female end socket of the traditional connector.

[0046] like Figures 1-6 As shown, in another embodiment of this utility model, the second connecting sleeve 220 includes a second snap-fit ​​portion 221 and a second locking portion 222. The second locking portion 222 is provided with a locking hole 223. A locking block 125 protrudes from the outer wall of the first locking portion 121 to snap into and adapt to the locking hole 223. A positioning block 224 is provided on the circumferential outer wall of the second snap-fit ​​portion 221. The inner ring of the second guide sleeve 210 is provided with a positioning groove for snapping into and adapting to the positioning block 224. The insertion and locking cooperation between the locking block 125 and the locking hole 223 ensures the stability of the insertion of the male connector 100 and the female connector 200. The guiding and limiting design of the positioning block 224 and the positioning groove realizes precise alignment during the insertion process, avoiding contact damage caused by misalignment of traditional connectors, and reducing the difficulty of insertion and removal operations.

[0047] like Figures 1-6As shown, in another embodiment of this utility model, the number of plug-in boards 300 is two sets, and the two sets of plug-in boards 300 are distributed at intervals within the male connector 100. The dual plug-in board 300 layout enables parallel transmission of multi-channel signals or power, reduces electromagnetic interference through spatial separation, and the two sets of plug-in boards 300 share the same guide sleeve and solder joint layout, which improves connection density while maintaining assembly efficiency, and avoids the problem of increased soldering complexity caused by the increase in the number of pins in traditional multi-pin connectors.

[0048] like Figures 1-6 As shown, in another embodiment of this utility model, there are two sets of female connector slots 400, and the two sets of female connector slots 400 are respectively aligned and arranged on the connector head 200. The dual female connector slots 400 are adapted to the dual connector board 300, expanding the channel capacity of the connector. The flexible pins 500 work independently in each female connector slot 400, ensuring the isolation and stability of the signals of each channel, and avoiding the short circuit risk caused by the close proximity of adjacent pin solder joints in traditional multi-pin connectors.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
