Description

Technical Field

[0001] The invention relates to a press-free electric plug connector, which overcomes the problem of inconvenience in plugging and unplugging the electric plug connector caused by narrow space. Background Art

[0002] like Figure 1 The existing electrical plug connector is shown, which includes an electrical plug connector body with a plug part, and a spring clip fixing seat 3' is provided at the end of the plug part, and a spring clip 2' with a reset function is fixed on the spring clip fixing seat 3' at one end, and fixed on the shell at the hinge of the flip plate 1' at the other end. When the electrical plug connector is plugged into a densely wired server, since the electrical plug connector is plugged into the interface of the server and fixedly connected thereto, when the electrical plug connector needs to be removed, it is difficult for a person's hand to reach the plug head of the electrical plug connector and press down the spring clip 2' to remove it due to the narrow spacing between the electrical plug connectors. If the electrical plug connector is forcibly pulled out without fully pressing down the spring clip 2', the plug part will be damaged, affecting the service life of the electrical plug connector, and the user experience will also be poor. Summary of the invention

[0003] In order to overcome the above disadvantages, the object of the present invention is to provide a pressure-free electric plug connector, which can press down a spring sheet at the rear of the electric plug connector to facilitate personnel to perform plugging and unplugging operations on the electric plug connector.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a press-free electric plug connector, including an electric plug connector body, a press-free disengagement device is arranged on the electric plug connector body, the press-free disengagement device includes a spring with a reset function, one end of the spring is fixed on the spring fixing seat, and it is characterized in that: the other end of the spring is linked with one end of a paddle with a pull-out reset function, the paddle is slidably arranged on the flip cover plate, and the other end of the paddle is a paddle part for finger paddle. The front end of the paddle is a stamping part, and its rigidity ensures the stability of the linkage, and the rear end is an injection molded part, which increases the safety and convenience during operation. The two ends are connected by embedded one-piece molding to ensure the stability of the paddle and increase the service life.

[0005] The present invention adds a paddle that can be moved externally, and designs the paddle to be in a linkage state with the spring sheet. The finger does not need to be inserted into the plug-in portion of the electrical plug connector, and the electrical plug connector can be removed from the interface of the server by simply pulling the paddle externally. The operation is convenient, and the user experience is affected effectively due to insufficient space in a densely wired server, and the service life problem caused by insufficient downward pressure of the spring sheet is effectively avoided.

[0006] Furthermore, one end of the spring piece is a semicircular groove with the notch facing upward, and one end of the paddle linked thereto is a circular overlap portion with a curved outer surface. The circular overlap portion is arranged in the semicircular groove, and a gap is provided on the paddle where the circular overlap portion is located outside for the semicircular groove end to be inserted; the junction of the semicircular groove and the circular overlap portion is the hinge position of the adjacent flip cover plate. The connecting surfaces between the semicircular groove and the circular overlap portion are both curved surfaces, so that when the flip cover plate is flipped over, the two can slide smoothly to avoid the problem of separation between the circular overlap portion and the semicircular groove. After the flip cover plate is closed (the flip cover plate is in the closed state when the electric plug connector is in use), the circular overlap portion and the end of the semicircular groove are buckled together, so that the paddle can drive the spring piece to move backward. Since one end of the spring piece is fixed, the downward pressing operation of the spring piece is realized. The above linkage method makes it easy to install the spring piece and the paddle.

[0007] Furthermore, the flip cover plate is provided with a slot for placing the paddle, and the flip cover plate located below the slot is also provided with a spring chamber connected to the slot, the bottom of the spring chamber is provided with a paddle avoidance groove, and a spring is provided in the spring chamber; the lower end surface of the paddle is provided with a paddle inserted into the spring chamber; the flip cover plate is provided with a limit assembly for pressing the paddle. The paddle slides on the flip cover plate in the above manner, and the paddle is reset by the spring reset.

[0008] Furthermore, the slot body includes an empty slot that passes through from top to bottom, and a bearing plate for placing a paddle is arranged in the empty slot; one end of the empty slot located on one side of the spring extends to the outside of the flip cover plate, and a recessed portion connected thereto is arranged on the flip cover plate where the other end of the empty slot is located, and the spring chamber is located in the recessed portion; an insertion slot is arranged on the flip cover plate where the outside of the spring chamber is located, and the width of the insertion slot is smaller than the outer diameter of the spring, and is connected to the spring chamber. The insertion slot is for inserting the paddle, and since there is no spring in it, the installation of the paddle is very convenient.

[0009] Furthermore, the limiting assembly includes a pair of limiting posts and a limiting railing distributed on both sides of the supporting plate, the limiting railing is horizontally arranged in the empty slot, and its two ends are connected to the flip cover plate; a pair of limiting posts are arranged on the two inner side walls of the empty slot.

[0010] Furthermore, the limiting railing is integrally formed with the flap plate, and the upper end surface of the limiting railing is in the same plane as the upper end surface of the flap plate. By designing in this way, the firmness and appearance of the limiting railing will be better.

[0011] Furthermore, the paddle has a first limiting groove for placing a limiting rail and a second limiting groove for placing a limiting clamping column, and the length of the paddle between the first limiting groove and the second limiting groove is greater than the length of the bearing plate. The paddle and the limiting clamping column can ensure the horizontal movement of the paddle on the one hand, and limit the forward and backward movement range of the paddle on the other hand, so as to avoid excessive pulling of the spring piece.

[0012] Furthermore, the upper end surface of the limit clamping column is a plane or curved surface that tilts downward from the inside to the outside, and the two side surfaces of the second limit groove match the upper end surface of the limit clamping column and are inclined surfaces tilted inwards. This makes it easy to install the second limit groove below the limit clamping column.

[0013] Preferably, the toggle portion extends outward to the outside of the flip cover plate and has a softer plastic pull ring at its tail to pull the paddle to achieve a press-free function. The toggle portion makes it convenient for on-site personnel to toggle the paddle with their fingers.

[0014] Preferably, the tail of the electrical plug connector body and the flip cover plate are provided with corresponding hooks and clamping points. In the example, after the cable is pressed into the electrical plug connector, the hooks and clamping points are fastened together, which makes it more convenient to install the rear pre-wire threaded fastening part.

[0015] Preferably, the rear of the electrical plug connector body and the flip cover plate is provided with upper and lower semicircular arc threaded plates, and when the cover plate and the body are buckled together, a cylindrical threaded opening is formed, and a pre-wire management device is provided on the threaded opening. The use of the pre-wire management device makes the electrical plug connector more convenient and beautiful in actual wiring. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with 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 protection scope of the present invention.

[0028] Example

[0029] See attached Figure 2 As shown in Figures 1 to 8, a press-free electric plug connector in this embodiment includes an electric plug connector body, and a press-free detachment device is provided on the electric plug connector body. The press-free detachment device includes a spring 2 with a reset function, one end of the spring 2 is fixed on a spring fixing seat 3, and the other end of the spring is linked with one end of a paddle 4 with a pull-out reset function. The paddle 4 is slidably arranged on the flip cover plate 1, and the other end of the paddle 4 extends to the outside of the flip cover plate 1 to form a paddle part for finger paddle. The front end of the paddle is a stamping part, and its rigidity ensures the stability of the linkage, and the rear end is an injection molded part, which increases the safety and convenience during operation. The two ends are connected by embedded one-piece molding to ensure the stability of the paddle and increase the service life. The user pulls the paddle part outward, and the paddle 4 drives the spring 2 to stretch outward. Since one end of the spring 2 is fixed, the spring 2 is pressed down and is separated from the server interface, and the electric plug connector can be directly pulled out. The electric plug connector described in this embodiment is convenient to operate and plug and unplug, and can overcome the problem of inconvenient unplugging operation on densely wired servers.

[0030] like Figure 4 As shown, in this embodiment, the flip cover plate 1 is first improved, and the paddle 4 can slide in the direction of its axis M. A vertically through-going slot 11 is provided in the direction of the axis M of the flip cover plate 1. A recessed portion 17 connected to the slot 11 is provided on the flip cover plate 1 away from the end of the elastic sheet 2. A portion of the slot 11 extends into the recessed portion 17, providing a sliding space for the paddle 4 to slide in the slot 11. Figure 4As can be seen in the figure, both the slot 11 and the recessed portion 17 are rectangular structures. A carrier plate 12 for placing the paddle 4 is provided in the slot 11, and a limit rail 13 and a limit column 15 are provided in the slot 11 at the front and rear sides of the carrier plate 12. The limit rail 13 is close to the side of the spring 2, and its upper end surface is in the same plane as the upper end surface of the flip cover plate 1; the limit column 15 is located on the side away from the spring 2, and there are two of them, which are symmetrically distributed on the two inner walls of the slot 11 about the axis M. Since the paddle 4 needs to be embedded under the limit column 15 when in use, the limit column 15 is designed at the upper edge of the slot 11, and the upper end surface of the limit column 15 is designed to be a downward inclined surface or an inclined curved surface, and the length of the limit column 15 is limited. In this embodiment, the length of the limit column 15 is limited to within 5 mm. A spring chamber 14 for placing the spring 5 is provided on the flip plate 1 at both sides of the recessed portion 17, and a toggle plate avoidance groove is provided at the bottom of the spring chamber. An insertion groove 16 connected to the spring chamber 14 is provided on the flip plate 1 at the side of the spring chamber 14 close to the spring sheet 2. The width of the insertion groove 16 is smaller than the diameter of the spring 5 to prevent the spring 5 from extending into the insertion groove 16. An upper semicircular threaded plate 19 is provided at the rear end of the flip plate 1, and a lower semicircular threaded plate 20 is provided at the rear end of the main body. The upper screw thread 19 and the lower threaded plate 20 form a cylindrical threaded opening after the flip plate and the main body are buckled, which is used to install the pre-wire thread fastening device. The tail of the flip plate 1 has a crimping plate downward, and a hook 18 is provided on the inner side of the crimping plate. A card point 5 corresponding to the hook 18 is provided on the main body of the electrical plug connector. In the example, the hook card point is buckled and fastened after the cable is pressed into the electrical plug connector, which is more convenient for the installation of the rear pre-wire thread fastening part.

[0031] like Figure 5 , Figure 6 As shown, the paddle 4 includes a first long strip substrate 41 placed in the empty slot 11, one end of the substrate is bent inward to form a circular overlap portion 44, and the other end of the substrate is provided with a second substrate 45 placed on the recessed portion 17, and the second substrate 45 is provided with a paddle piece 46 that can be inserted into the insertion slot 16, and the outer side of the second substrate 45 is provided with a paddle portion for personnel to paddle, and the paddle portion includes a pull ring 47 and a paddle connector 48 fixedly connected to the pull ring 47 at one end, and the pull ring 47 is made of softer plastic, and the other end of the paddle connector 48 is connected to the second substrate 45. The first substrate 41, the second substrate 45, the circular overlap portion 44, the paddle piece 46, the paddle connector 48, and the pull ring 47 are integrally formed. In this embodiment, the center line of the first substrate coincides with the center line of the second substrate 45, and the number of the paddle pieces 46 is two, and they are symmetrically distributed with respect to the above-mentioned center line. Figure 5 , 6As can be seen in the figure, the first substrate is provided with a first limiting groove 42 which is concave downwards near the circular overlap portion 44, and there is a gap between the first limiting groove 42 and the circular overlap portion 44 for the spring 2 to be inserted. The first substrate 41 which is close to the second substrate 45 has a second limiting groove 43 which is concave downwards. The first substrate between the first limiting groove 42 and the second limiting groove 43 is placed on the carrier plate 12, and its length is greater than the length of the carrier plate 12, so that the first substrate can slide on the carrier plate 12. Figure 2 As shown, during assembly, the limiting rail 13 is placed in the first limiting groove 42, and the limiting post 15 is located in the second limiting groove 43. At the same time, in order to facilitate the second limiting groove 43 to be embedded under the limiting post 15, the two sides of the groove body of the second limiting groove 43 are provided with inclined surfaces 48 inclined inwardly. When the first substrate is pressed down, it cooperates with the upper end surface of the limiting post 15 to facilitate the second limiting groove 43 to be embedded under the limiting post 15. At the same time, the limiting rail 13 is placed in the first limiting groove 42, and the limiting post 15 is placed in the second limiting groove 43, which also limits the sliding range of the paddle 4 on the flip cover 1.

[0032] like Figure 3 As shown, the spring piece 2 in this embodiment has the same structure as the existing spring piece, and both include a locking step 23, a fixed block 21 at one end of the locking step 23, and fixed posts 22 at both ends of the fixed block 21. The difference is that: the other end of the locking step 23 is provided with a connecting plate 24, and the tail of the connecting plate 24 is a semicircular groove 25. The fixed block 21, the fixed post 22, the locking step 23, the connecting plate 24, and the semicircular groove 25 are integrally formed. In this embodiment, the notch of the semicircular groove 25 faces upward, and a circular overlap portion 44 is placed therein. The front end of the semicircular groove 25 is inserted into the gap between the first limiting groove 42 and the circular overlap portion 44, so that the circular overlap portion 44 and the semicircular groove 25 are in a linkage state, so that the paddle 4 drives the spring piece 2 to move outward. Since the flip cover 1 will flip upward in actual use, the contact surfaces of the circular overlap portion 44 and the semicircular groove 25 are both curved surfaces, which can conveniently and smoothly adjust the position between the two as the flip cover 1 flips, avoiding the problem of separation between the circular overlap portion 44 and the semicircular groove 25.

[0033] The PCB board shown in FIG. 8 (a, b, c) optimizes the transmitted signal through the lines thereon, so that the electrical plug connector in this embodiment can meet the international Category 8 transmission standard.

[0034] The present invention adds a paddle to a traditional electric plug connector and improves the original flip cover plate and spring sheet, so that a person can paddle the spring sheet from the outside of the flip cover plate, and the invention has the advantages of convenient operation and easy plugging and unplugging.

[0035] The above implementation modes are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
