Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection devices, in particular to a connector used for realizing electrical connection between electronic devices. Background Art

[0002] Many electronic products, such as those used in vehicles and energy storage devices, use connectors to achieve electrical connections for power supply and signal transmission. Prior art connectors with curved springs are typically used for flat male terminals. The springs' inherent elastic force clamps the male terminals to achieve a connection between the male and female terminals, as exemplified by the female connector disclosed in Chinese Utility Model Patent No. 202220813009.4 and the anti-kneeling PIN connector disclosed in Chinese Utility Model Patent No. 202222443038.9. However, the female housings of existing connectors of this type are typically significantly shorter than the springs and lack protective structures, leaving the springs exposed. This provides insufficient support for the springs after they are subjected to force, and the lack of protective measures makes them susceptible to damage from external impacts. Furthermore, some springs have curved portions that protrude outward, making their stability susceptible to external influences. For this reason, although some horizontal female connectors for side-insertion use an enclosure structure, whereby the female terminals (springs) are held in the middle by the outer sides of the female terminals to protect them, the enclosure structure on the lower side of the side-insertion method is designed to increase the ground contact area, making it easier to set the plug pins and to increase the stability of the fit between the plug pins (the greater the distance between the plug pins, the less likely they are to fall over). At the same time, the enclosure structure on the other side (i.e., the upper side) can only resist external impacts on one side of the vertical plane, and cannot resist impacts from the sides. Utility Model Content

[0003] The utility model addresses the defects in the prior art that the spring clip protrudes too high and has no protective structure around it, resulting in insufficient support and susceptibility to damage from collisions with foreign objects. It provides a high-strength and high-stability direct-plug female connector with a more reasonable structural design, a smaller protrusion height of the spring clip relative to the female shell, the ability to withstand impacts from both sides, and a protective structure for the spring clip.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a high-strength and high-stability straight-plug female connector, comprising a female shell and a spring clip, the female shell being made of conductive metal, and having an insertion channel inside the female shell; each spring clip extends from the head end of the female shell and then bends back toward the inside of the female shell and penetrates into the insertion channel to form a relative clamping structure, and the male terminal is inserted between the spring clips in an upright direction and is clamped by each spring clip to form a structure perpendicular to the plate end, which is characterized in that: two covering protrusions are formed by protruding upward on both sides of the head end of the female shell, and grooves are formed on the other two sides of the female shell between the covering protrusions on both sides, and each spring clip extends upward at the bottom of the groove and then bends toward the inside of the female shell and penetrates into the insertion channel, and the covering protrusions block the outside of both sides of the spring clip to achieve blocking the spring clip in the middle.

[0005] Furthermore, the covering protrusion is a U-shaped structure, and its two sides extend toward the spring sheet to form an extension portion, which is close to the side of the spring sheet but has a gap between it and the spring sheet; the groove is located between the extension portions on the same side, that is, the two grooves are arranged on the opposite side walls of the female end shell.

[0006] Furthermore, the raised height of the covering convex portion is smaller than the raised height of the spring piece, and the middle and lower parts of the spring piece are located below the covering convex portion to be shielded, with only a small part protruding upwards above the covering convex portion.

[0007] Preferably, the spring pieces are of W-shaped or wavy structure, and the two rows of spring pieces are of bilaterally symmetrical structure, and one or more spring pieces can be provided in each row.

[0008] Furthermore, the spring piece extends straight upward from the bottom of the groove and then bends in an arc shape into the interior of the female end housing, and the outer surface of the spring piece does not protrude from the outer surface of the female end housing.

[0009] Preferably, the covering protrusion is an integral structure with the female end housing and the spring piece, and the extension portion is formed by bending along with the female end housing.

[0010] Furthermore, the bottom of the female housing is equipped with plugging and stabilizing pins. The plugging pins extend downward to form a structure for plugging and securing the connector to the board. The insertion direction of the plugging channel is the same as the extension direction of the plugging pins, forming a vertical connector. The stabilizing pins extend outward to form an L-shaped structure that supports the surface of the board (PCB) to improve the stability of the spring clip and the PCB.

[0011] Preferably, the plug pins and the stabilizing pins are formed by stamping or punching, and the plug pins and the stabilizing pins are an integral structure with the female end housing.

[0012] By raising the sides of the female housing to form a covering protrusion, the spring sheet is almost completely blocked by the two covering protrusions. This not only improves the supporting strength of the spring sheet, but also protects the spring sheet by reducing damage caused by external objects hitting the spring sheet from the sides, and can resist horizontal upward external impact. In addition, the curved portion of the spring sheet does not protrude beyond the outer side of the female housing, thus preventing interference from external impacts, thereby improving the conductive stability, strength, and anti-interference performance of the female connector.

[0017] In this embodiment, refer to Figure 1-Figure 3 The high-strength and high-stability female connector 1 includes a female housing 11 and springs 12. The female housing 11 is made of conductive metal and has a plug-in channel inside. Each spring 12 extends from the head end of the female housing 11 and then bends back toward the inside of the female housing 11 and penetrates into the plug-in channel to form a relative clamping structure. The male terminal 2 is inserted between the springs 12 in an upright direction and is clamped by each spring 12 to form a structure perpendicular to the board end (i.e., the PCB board 3), i.e., the male terminal 2 is perpendicular to the PCB board 3; two covering protrusions 13 are formed on the front and rear sides of the head end of the female end shell 11, and grooves 15 are formed on the other two sides (left and right sides) of the female end shell 11 between the covering protrusions 13 on both sides. After each spring piece 12 extends upward from the bottom of the groove 15, it is bent into the interior of the female end shell 11 and inserted into the plug-in channel. The covering protrusions 13 are blocked on both sides of the spring piece 12 to block the spring piece 12 in the middle, so as to protect the spring piece 12.

[0018] The covering protrusion 13 is a U-shaped structure, with its two sides extending toward the spring 12 to form an extension portion 14, which can enhance the structural strength of the entire female end housing 11. The extension portion 14 is close to the side of the spring 12 but has a gap between it and the spring 12; the groove 15 is located between the extension portions 14 on the same side, that is, the two grooves 15 are provided on the left and right opposite side walls of the female end housing 11.

[0019] The raised height of the covering protrusion 13 is smaller than the raised height of the spring piece 12. The middle and lower parts of the spring piece 12 are located below the covering protrusion 13 to be shielded, and only a small part protrudes upward above the covering protrusion 13. In this way, when a foreign object collides with it, it will usually hit the covering protrusion 13 first.

[0020] The spring clips 12 have a wavy (or W-shaped) structure, which increases the electrical contact area, boosting the current flowing through it, while also increasing friction and providing greater clamping force. The two rows of spring clips 12 are bilaterally symmetrical, with one or more spring clips 12 per row. Multiple spring clips 12 must be spaced a certain distance apart.

[0021] The spring piece 12 extends straight upward from the bottom of the groove 15 and then bends into the interior of the female housing 11 in an arc shape. The outer surface of the spring piece 12 does not protrude from the outer surface of the female housing 11 to avoid being hit by foreign objects.

[0022] The covering protrusion 13 is an integral structure with the female housing 11 and the spring piece 12 , and the extension portion 14 is formed by bending along with the female housing 11 .

[0023] The bottom of the female housing 11 is equipped with plug pins 16 and stabilizing pins 17. The plug pins 16 extend downward to form a structure for plugging and securing the female end (i.e., PCB 3). The insertion direction of the plug channel is the same as the extension direction of the plug pins, forming a vertical connector, as opposed to a sideways connector. The stabilizing pins 17 extend outward to form an L-shaped structure that supports the surface of the PCB 3, thereby enhancing the stability of the spring 12 in the PCB 3. This symmetrical arrangement prevents the female end from becoming unstable and tilting after the plug pins 16 are inserted into the PCB 3, thereby ensuring the stability of the connector during the soldering process and subsequent use.

[0024] The plug pin 16 and the stabilizing pin 17 are formed by stamping or punching, and the plug pin 16 and the stabilizing pin 17 are an integral structure with the female end housing 11 .

[0025] It should be noted that the description of the directions such as up, down, left, and right in this embodiment is based on the attached Figure 1-3 In the embodiment of the viewing angle, for example, the covering protrusion 13 is facing upward, the plug pin 16 is facing downward, and the stabilizing pin 17 is facing left and right respectively. When the viewing angle changes, the directions should also change accordingly.

[0026] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
