[0007] Preferably, the elastic component includes an outer tube installed at the bottom of the groove along a first direction, an inner tube sleeved in the outer tube and capable of sliding up and down relative to the outer tube, and a spring arranged in the outer tube and the inner tube, the lower end of the spring acts on the lower end of the outer tube, the upper end of the spring acts on the top of the inner tube, the upper end of the inner tube abuts against the lower surface of the protective cover, and the elastic component can push the protective cover to the first end of the low-position pin in a natural state, so that the first end of the low-position pin is accommodated in the through hole, and multiple elastic components are arranged along the edge of the groove and located on the periphery of the pin array.
[0008] Preferably, the length of the elastic component in the natural state is twice the length of the elastic component in the fully compressed state.
[0009] Preferably, when the elastic component is in a natural state, the first end of the high-position pin extends from the through hole of the protective cover, and the first end of the low-position pin is accommodated in the through hole.
[0010] Preferably, the port of the outer tube is tightened to form an anti-slip ring, and a limiting protrusion is provided at the bottom of the outer wall of the inner tube. The limiting protrusion can be blocked by the anti-slip ring to prevent the inner tube from escaping from the port of the outer tube. The upper port of the inner tube is tightened to form a necked end, and the top of the spring is blocked by the necked end.
[0011] Preferably, the movement range of the protective cover is between the highest position and the lowest position. When the bottom of the inner tube contacts the bottom of the outer tube, the protective cover reaches the lowest position; when the limiting protrusion is blocked by the anti-slip ring, the protective cover reaches the highest position.
[0012] Preferably, the pin is a bent pin, the first end of the pin extends along a first direction and is located in the groove of the base, the second end of the pin extends along a second direction and extends from the side of the base, and the first direction and the second direction are perpendicular to each other.

[0016] By means of the above technical solution, the beneficial effects of the present invention are as follows:
[0017] 1. When the connectors of the present application are docked, the guide posts first contact and guide the positioning, so that the connectors are accurately aligned. Then the high-position pins contact first, and finally the low-position pins contact, forming a graded insertion. This structural design can prevent the pins from being bent or damaged due to misoperation or tilted insertion, and at the same time can use the first contact of the high-position pins to share mechanical stress.
[0018] 2. The outer and inner tubes of the elastic assembly of this application are nested, expanding the compression space of the spring to the combined lengths of the inner and outer tubes. When the protective cover is pressed down, the inner tube can be completely retracted into the outer tube, increasing the elastic assembly's telescopic distance. The spring is confined within the outer and inner tubes, limiting radial displacement of the spring and preventing skew and shaking during expansion and contraction, thereby making the spring's expansion and contraction more stable. In addition, multiple elastic assemblies are arranged along the edges of the grooves around the periphery of the pin array, enhancing the force balance of the protective cover and ensuring smoother movement of the cover.
[0019] 3. The connector of the present application uses a protective cover to cover the pin array to prevent the pins from being contaminated by dust or mechanically damaged; the elastic component enables the protective cover to have an automatic reset function. When an external force presses down the protective cover to expose the pins for connection operation, the protection state can be restored by removing the external force, thereby improving the convenience of use and protection reliability; the protective cover slides along the pin guide to avoid the deflection of the pins caused by the plugging and unplugging process; the buffering design of the elastic component can also absorb the impact force during the plugging process, which not only extends the service life of the connector but also improves the operating feel.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] It should be noted that, in the description of the present invention, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0031] like Figure 1As shown, a connector with an elastic protective cover of the present application, the connector includes a base 1, the base 1 is provided with a groove, the bottom of the groove is arrayed with a plurality of pins 3, the pins 3 include low-position pins 31 and high-position pins 32, and a plurality of guide columns 6 are also provided in the groove. In a first direction, the first end 33 of the high-position pin 32 is higher than the first end of the low-position pin 31, the end of the guide column 6 extends beyond the groove, and the first end of the high-position pin 32 is lower than the groove. A protective cover 2 is positioned within the groove and is capable of sliding in a first direction within the groove. The protective cover 2 is formed with a plurality of through-holes through which the first ends of the pins 3 can extend. The groove is also provided with a plurality of elastic components, which are configured to exert an upward restoring force on the protective cover 2 when the protective cover 2 is pressed downward. The connector has a mated state and an undocked state. When the connector is in the undocked state, the first ends of the pins 3 are located within or extend from the through-holes. During the docking process, the connectors are inserted in the following order: guided by the guide post 6, then the higher pins 32, and finally the lower pins 31. This structure creates a stepped insertion mechanism, preventing the pins 3 from bending or damage due to misoperation or tilted insertion. It also distributes mechanical stress by allowing the higher pins 32 to make contact first. The protective cover 2 protects the pins 3 from dust contamination or mechanical damage. The elastic components provide the protective cover 2 with an automatic reset function. When an external force presses down on the protective cover 2, exposing the pins 3 for connection, the protective state is restored upon removal of the external force. In addition, the protective cover 2 slides along the guide of the pin 3 to avoid the deflection of the pin 3 during the plugging and unplugging process, and the buffer design of the elastic component can also absorb the impact force during the plugging process.
[0032] like Figure 4 and 5The figure shows the elastic assembly of the present application. The elastic assembly includes an outer tube 51 mounted at the bottom of the groove along a first direction, an inner tube 52 sleeved within the outer tube 51 and capable of sliding up and down relative to the outer tube 51, and a spring 53 disposed within the outer tube 51 and the inner tube 52. The lower end of the spring 53 acts on the lower end of the outer tube 51, and the upper end of the spring 53 acts on the top of the inner tube 52. The upper end of the inner tube 52 abuts the lower surface of the protective cover 2. The outer tube 51 and the inner tube 52 of the elastic assembly of the present application are nested, so that the compression space of the spring 53 expands to the superimposed space of the length of the inner and outer tubes 51. When the protective cover 2 is pressed downward, the inner tube 52 can be completely retracted into the outer tube 51, increasing the elastic assembly's telescopic distance. In addition, the spring 53 is confined within the outer tube 51 and the inner tube 52, limiting radial deviation of the spring 53, preventing the spring 53 from skewing or shaking during telescopic movement, and making the telescopic movement of the spring 53 more stable. In a preferred embodiment, the length of the elastic component in the natural state is twice the length of the elastic component in the fully compressed state.
[0033] like Figure 1 As shown, multiple elastic components are arranged along the edges of the groove, located outside the pin array. This layout avoids the central pin arrangement area, ensuring that the protective cover 2 receives evenly distributed elastic support during its vertical movement, effectively preventing deflection and jamming. The elastic components arranged at the edge complement the central pin 3 area, achieving maximum functional integration within a limited space and improving the space utilization and operational reliability of the connector.
[0034] In a preferred embodiment, the elastic component can push the protective cover 2 to the first end of the low-position pin 31 in a natural state, so that the first end of the low-position pin 31 is accommodated in the through hole. Figure 6 and 7 As shown, when the elastic component is in a natural state, the first end of the high-position pin 32 extends from the through hole of the protective cover 2, and the first end of the low-position pin 31 is accommodated in the through hole, so that the high-position pin 32 plays a guiding role.
[0035] like Figure 4 and 5As shown, the end of the outer tube 51 is tightened to form an anti-slip ring 511, and the bottom of the outer wall of the inner tube 52 is provided with a limiting protrusion 522. The limiting protrusion 522 can be blocked by the anti-slip ring 511 to prevent the inner tube 52 from escaping from the end of the outer tube 51. The upper end of the inner tube 52 is tightened to form a constricted end 521, and the top of the spring 53 is blocked by the constricted end 521. The movement range of the protective cover 2 is between the highest position and the lowest position. When the bottom of the inner tube 52 contacts the bottom of the outer tube 51, the protective cover 2 reaches the lowest position; when the limiting protrusion 522 is blocked by the anti-slip ring 511, the protective cover 2 reaches the highest position.
[0036] like Figure 8 As shown, the pins are curved, and the first ends of the high-position pins 32 and / or low-position pins 31 are tapered. The first ends of the pins extend in a first direction and are located within the groove of the base 1. The second ends 34 of the pins extend in a second direction and extend from the side of the base 1. The first and second directions are perpendicular to each other.
[0037] like Figure 2 and 3 As shown, the inner wall of the groove is provided with a plurality of stop pins, and the stop pins are located above the protective cover 2 to prevent the protective cover 2 from falling out upwards. Figure 2 As shown in FIG, the protective cover 2 reaches the highest position. At this time, only the upper end of the pin 3 passes through the protective cover 2 and is exposed from the upper side of the protective cover 2. The stop pin 4 is located above the protective cover 2 to prevent the protective cover 2 from falling off from above the pin 3. Figure 3 As shown, the protective cover 2 reaches the lowest position. At this time, the inner tube 52 is compressed to the bottom.
[0038] The above embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
