Specific embodiments

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] Refer to Figures 1 to 6 for further description of the embodiments of the present utility model.

[0029] A lying - type connector includes a housing 1. An insertion socket groove 12 and a limiting hole 29 are formed on the housing 1. The limiting hole 29 is located above the insertion socket groove 12. A plurality of terminals 2 are inserted into the housing 1. The terminal 2 includes a welding part 21 and a connecting part. The connecting part is located in the insertion socket groove 12, and the welding part 21 is located on the back of the insertion socket groove 12 of the housing 1 for welding a circuit board. The connecting part includes an elastic part 22 and a fixing part. A fixing gap is formed between the elastic part 22 and the fixing part. When in use, a mating plug is inserted into the insertion socket groove 12, so that the mating terminals on the mating plug are inserted into the fixing gap. The two sides of the mating terminals are respectively in contact with the elastic part 22 and the fixing part to achieve electrical connection.

[0030] Refer to Figure 1 , limiting protrusions 23 are formed on both sides of each elastic part 22 in the insertion socket groove 12. The limiting protrusions 23 are evenly distributed on one side of the insertion socket groove 12 close to the limiting hole 29. The elastic part 22 can be resisted and limited from both sides by the limiting protrusions 23. Such a design can ensure that during mating, the elastic limiting end 25 can be stably maintained in the limiting gap 24. The cooperation between the elastic limiting end 25 and the limiting gap 24 can effectively limit the movement range of the elastic part 22 on the terminal 2, thereby reducing the stress and deformation generated during insertion. This design not only improves the stability of insertion but also extends the service life of the components.

[0031] Refer to Figure 4 , an abutting part 26 is further formed on the elastic part 22. When connected to the mating terminal, the elastic part 22 deforms to provide additional support to ensure the stability of electrical connection. Specifically, when the elastic part 22 deforms, the abutting part 26 can abut against the mating terminal for connection, thus ensuring the stability and reliability of electrical connection.

[0032] Refer to Figure 1 , a keying groove 27 communicating with the insertion socket groove 12 is provided on the housing 1. The keying groove 27 is arranged on the left and right sides of the insertion socket groove 12. A keying boss is correspondingly arranged at the corresponding position of the mating plug. When the mating plug is inserted into the insertion socket groove 12, only when the keying boss corresponds to the keying groove 12 in position, the mating plug can be inserted into the insertion socket groove 12, otherwise it cannot be inserted. In this way, misoperation during the insertion process can be effectively avoided. This design not only improves the user experience but also reduces the potential damage risk caused by misinsertion.

[0033] Meanwhile, the two positioning holes 28 provided on the housing 1 are distributed on both sides of the limiting hole 29, and the positions of these positioning holes 28 correspond one-to-one with the anti-fooling grooves 27. Positioning blocks will be provided at the corresponding positioning holes 28 on the mating plug. When the mating plug and the socket slot 11 are plugged together, the positioning blocks are inserted into the positioning holes 28, thereby enhancing the reliability of the connection between the mating plug and the connector. And this design ensures that during installation, the components can be accurately aligned, avoiding poor connection or unstable contact caused by position deviation. The combined use of the positioning holes 28 and the anti-fooling grooves 27 improves the stability of the overall structure and the reliability of the connection.

[0034] Refer to Figure 1 , a positioning buckle 291 is provided inside the limiting hole 29, and a slope is formed on the front surface of the positioning buckle 291. When the docking plug is plugged in, the design of the slope can effectively guide the elastic buckle on the docking plug to be clamped after passing through the positioning buckle 291, reducing the contact interference. Moreover, two limiting depressions 293 are symmetrically arranged on the side of the positioning buckle 291 facing away from the slope, further enhancing the reliability of the connection. These limiting depressions 293 cooperate with the protrusions on the elastic buckle of the docking plug to form a stable clamping structure, ensuring that it can effectively prevent shaking after the two are clamped, reducing the risk of loosening caused by vibration or external force.

[0035] Refer to Figure 1 , a diversion groove 9 is formed on the housing 1. The diversion groove 9 is located on the side of the housing 1 opposite to the socket slot 12 and is provided on the side close to the welding part 21. At the same time, a number of partition pieces 91 are provided in the diversion groove 9. The partition pieces 91 can divide the diversion groove 9 into several non-connected small gaps. Such a layout can effectively guide the solder to the predetermined area. During the welding process, if the welding wire is welded excessively, it can guide the excess solder to flow smoothly into the diversion groove 9 instead of overflowing into the adjacent gaps or other areas that do not need to be welded, avoiding the short-circuit phenomenon caused by the solder connecting the adjacent terminals 2, thereby enhancing the reliability and safety of the electrical connection, improving the overall efficiency of the welding process, and reducing the rework probability caused by solder overflow.

[0036] Refer to Figure 3 , 6, a solder tab groove 3 is provided on each of the left and right sides of the housing 1, and a solder tab 4 is inserted and engaged in the solder tab groove 3. The solder tab 4 also protrudes with a first fixing leg 51, a second fixing leg 52 and a third fixing leg 53. The first fixing leg 51, the second fixing leg 52 and the third fixing leg 53 are arranged on the solder tab 4 in sequence. The setting of these fixing legs can not only increase the fixing stability of the solder tab 4 on the housing 1, but also ensure accurate positioning. At the same time, the second fixing leg 52 is arranged between the first fixing leg 51 and the third fixing leg 53, and the lengths of the first fixing leg 51, the second fixing leg 52 and the third fixing leg 53 gradually become shorter in sequence. The solder tab 4 is provided with a first welding end 41 and a second welding end 42. The first welding end 41 is arranged on one side of the first fixing leg 51. The first welding end 41 and the second welding end 42 are integrally formed with the solder tab 4. At the same time, the positions of the second welding end 42 and the first welding end 41 on the solder tab 4 are in an L shape. In this way, when the connector is fixedly connected to the circuit board, the first welding end 41 and the second welding end 42 can be selectively welded and fixed to the circuit board to meet the need of the connector being fixedly connected to the circuit board in different orientations.

[0037] A locking portion 54 that engages with the solder tab groove 3 protrudes from the second fixing leg 52. When the solder tab 4 is inserted into the solder tab groove 3, the locking portion 54 is in interference fit with the solder tab groove 3 for fixation, which can resist loosening caused by external factors such as temperature change and vibration to a certain extent and ensure the long-term stability of the welding part.

[0038] An anti-disengagement groove 6 is recessed on the first fixing leg 51. A hook 62 is also formed on the first fixing leg 51 at the inner groove opening position of the anti-disengagement groove 6. A clamping protrusion 61 that is engaged with the hook 62 protrudes from the solder tab groove 3. A guiding surface is provided on the outer side of the hook 62. When the clamping protrusion 61 is inserted, the guiding surface design can effectively promote the smooth entry of the clamping protrusion 61 to ensure a fast and safe connection process. A clamping depression 63 that cooperates with the hook 62 to prevent disengagement is formed on the clamping protrusion 61. The cooperation between the hook 62 and the clamping depression 63 further restricts the disengagement of the solder tab 4. A semi-circular groove 64 facing its opening is provided at the inner end of the anti-disengagement groove 6. The semi-circular groove 64 is communicated with the anti-disengagement groove 6. The existence of the semi-circular groove 64 can enable the two parts of the first fixing leg 51 divided by the anti-disengagement groove 6 to better adapt to elastic deformation.
