Description

Technical Field

[0001] The present invention relates to the technical field of network wiring, and in particular to a locking member and a cable connector of a buckling structure. Background Art

[0002] The cable connector is used to establish a network connection between two cables, or to establish a network connection between a cable and an electrical appliance. In the prior art, in order to ensure a stable connection between the cable and the cable connector, the cable and the cable connector are generally fixed by a clamp structure, but the clamp structure increases the length of the cable connector. In some working conditions, the size of the cable connector is required not to be too large, which requires the design of a cable connector that can not only meet the requirements of cable fixation, but also does not take up extra space.

[0003] For example, a crystal head connector in patent CN117276966B is hinged with an upper cover and a lower cover, and the second buckle and the second slot are engaged to fix the cable in the cable hole formed by the upper cover and the lower cover. However, in actual application, if the cable is pulled in the opposite direction of the engagement of the second buckle and the second slot (i.e., the direction of releasing the engagement), it is very easy to cause the engagement part to loosen (the second buckle is separated from the second slot), thereby affecting the stable connection between the cable and the cable connector. Summary of the invention

[0004] In order to overcome the above disadvantages, the purpose of the present invention is to provide a locking member and a cable connector with a snap-fit ​​structure, which can effectively prevent the upper cover and the lower shell from loosening during use and improve the stable connection between the cable and the cable connector.

[0005] In order to achieve the above objectives, one of the technical solutions adopted by the present invention is: a locking member with a snap-fit ​​structure, the snap-fit ​​structure is used to snap the upper cover to the lower shell; the locking member includes a pressing plate pressed against the snap-fit ​​structure, and the pressing plate is provided with a first fastener, a second fastener, and a third fastener that can be snapped to the upper cover, the lower shell, and the snap-fit ​​structure respectively.

[0006] The locking member of the buckle structure of the present invention has the following beneficial effects:

[0007] First, by pressing the pressing plate against the snap-fit ​​structure, a certain pressure can be applied to the snap-fit ​​structure, thereby enhancing the stability of the snap-fit ​​structure to a certain extent; then, by directly snapping the third fastener with the snap-fit ​​structure, the snap-fit ​​force of the snap-fit ​​structure is enhanced, thereby effectively preventing the snap-fit ​​structure from loosening; then, the upper cover and the pressing plate are snapped together by the first fastener, and the lower shell and the pressing plate are snapped together by the second fastener, and the pressing plate is restricted by the upper cover and the lower shell to ensure the stability of the position of the pressing plate, thereby indirectly improving the stability of the snap-fit ​​structure.

[0008] By limiting the limiting relationship of the pressing piece by the first fastener, the second fastener and the third fastener, the first fastener, the second fastener and the third fastener can cooperate with each other to form mutual constraints on the pressing piece in three directions that are perpendicular to each other, thereby ensuring the stability of the position of the pressing piece during use and ensuring the stable constraints of the pressing piece on the snap-fit ​​structure; and any one of the first fastener, the second fastener and the third fastener is limited to forming a restriction on the pressing piece in two vertical directions at most, thereby ensuring that the first fastener or the second fastener can release the snap-fit ​​relationship with the upper cover or the lower shell from the third direction that is not restricted, thereby facilitating the rapid locking or unlocking of the locking member and the cable connector.

[0009] In order to achieve the above purpose, the second technical solution adopted by the present invention is: a cable connector, comprising an upper cover and a lower shell, wherein one end of the upper cover along its length direction is hinged on the lower shell, and the other end is buckled on the lower shell through a buckling structure; and further comprising a locking member for preventing the buckling structure from loosening, wherein the locking member comprises a pressing piece pressed against the buckling structure, and the pressing piece is provided with a first buckle, a second buckle, and a third buckle which can be buckled to the upper cover, the lower shell, and the buckling structure respectively:

[0010] The first fastener, the second fastener, and the third fastener can jointly restrain the pressing plate from moving in three directions that are perpendicular to each other; and any one of the first fastener, the second fastener, and the third fastener can at most only restrain the pressing plate from moving in two perpendicular directions.

[0011] It should be noted that the three directions perpendicular to each other refer to the three directions along the length, width and height of the upper cover, while the length, width and height of the lower shell are consistent with those of the upper cover.

[0012] The beneficial effects of the cable connector of the present invention are:

[0013] 1. In the locking member, firstly, the pressing piece is pressed against the buckling structure, which can exert a certain pressure on the buckling structure, thereby enhancing the stability of the buckling structure to a certain extent; then, the buckling force of the buckling structure is enhanced by the direct buckling of the third fastener with the buckling structure, thereby effectively inhibiting the buckling structure from loosening; then, the upper cover and the pressing piece are buckled by the first fastener, and the lower shell and the pressing piece are buckled by the second fastener, and the upper cover and the lower shell are used to restrict the pressing piece to ensure the stability of the position of the pressing piece, thereby indirectly improving the stability of the buckling structure;

[0014] 2. By limiting the limiting relationship of the first fastener, the second fastener, and the third fastener on the pressing piece, the first fastener, the second fastener, and the third fastener can cooperate with each other to form mutual constraints on the pressing piece in three directions perpendicular to each other, thereby ensuring the stability of the position of the pressing piece during use and ensuring the stable constraints of the pressing piece on the buckling structure; and any one of the first fastener, the second fastener, and the third fastener is limited to only form a restriction on the pressing piece in two vertical directions at most, so as to ensure that the first fastener or the second fastener can release the buckling relationship with the upper cover or the lower shell from the third direction that is not restricted, thereby facilitating the rapid locking or unlocking of the locking member and the cable connector;

[0015] 3. Through the cooperation of the first fastener, the second fastener, the third fastener and the fastening structure on the pressing piece, a fastening relationship at multiple points can be formed between the upper cover and the lower shell, and the fastening relationships at multiple points can restrict each other to enhance the connection stability between the upper cover and the lower shell, avoid the loosening of the fastening relationship at a single point due to cable pulling during use, and ensure the connection stability of the cable and the cable connector.

[0016] Further, the snap-fit ​​structure includes snap-fit ​​plates and buckles that are arranged in a one-to-one correspondence, one of the snap-fit ​​plates and the buckle is arranged on the upper cover, and the other is arranged on the lower shell, and the snap-fit ​​plate is provided with a slot for the buckle to be embedded in along the length direction of the upper cover; the pressing sheet includes a pressing sheet body, and a pressing plate that is arranged in a one-to-one correspondence with the snap-fit ​​plate is integrally provided on the pressing sheet body, and the pressing plate is pressed against the corresponding snap-fit ​​plate, and its two sides along the height direction of the upper cover are respectively abutted against the upper cover and the lower shell; each of the pressure plates is provided with a third fastener that can be embedded in the slot on one side facing the snap-fit ​​plate, and the third fastener and the buckle are respectively embedded in the slot from both sides of the slot.

[0017] By abutting the two sides of the pressure plate along the height direction of the upper cover against the upper cover and the lower shell, the upper cover and the lower shell can be used to limit the pressure plate along the height direction of the upper cover; then the third fastener is embedded in the slot to limit the third fastener by using the slot, thereby further suppressing the limitation of the pressure plate along the height direction of the upper cover. At the same time, the third fastener and the buckle are embedded in the slot, which can enhance the clamping strength and further suppress the third fastener and the buckle from loosening from the slot.

[0018] Furthermore, a limiting strip is provided on the side of the pressure plate facing the buckle plate; when the third fastener is embedded in the slot, a gap is formed between the upper cover or lower shell provided with the buckle and the buckle plate for the limiting strip to be inserted, so as to further suppress the displacement of the pressure plate along the height direction of the upper cover.

[0019] Furthermore, a first slot is provided on one side of the upper cover facing the lower shell for the first fastener to be inserted into, and the first slot inhibits the first fastener from moving along the length direction of the upper cover. By limiting the first fastener with the first slot, the pressing piece can be inhibited from detaching from the upper cover in the length direction of the upper cover.

[0020] Furthermore, a second card slot for the second fastener to be inserted is provided on a side of the lower shell away from the upper cover; the second fastener is bent and arranged on the pressing sheet, and the second card slot inhibits the second fastener from moving along the length direction and the width direction of the upper cover. Since the cable is connected between the lower shell and the upper cover, the second card slot is arranged on the side of the lower shell away from the upper cover to prevent the cable from touching the engaging part of the second fastener and the second card slot when being pulled, thereby preventing the second fastener and the second card slot from being loosened due to the cable being pulled.

[0021] Furthermore, the second fastener includes a bending plate integrally provided on the pressing plate body, and a second buckle capable of being embedded in the second clamping groove is provided on a side of the bending plate facing the lower shell.

[0022] Furthermore, the lower shell is provided with a recessed slot for accommodating the bending plate. The bending plate can be partially accommodated in the lower shell by the provision of the recessed slot, so as to minimize the increase in the size of the cable connector caused by the provision of the bending plate.

[0023] Furthermore, a finger slot communicating with the second slot is provided on a side of the lower shell away from the upper cover, so that a finger can be inserted into the finger slot to release the engagement between the second fastener and the second slot.

[0024] Furthermore, the upper cover and the lower shell are provided with a pressing piece receiving groove for receiving the pressing piece at one end along the length direction thereof, so as to minimize the change in the length dimension of the cable connector caused by the setting of the pressing piece.

[0025] Furthermore, the lower shell is provided with a disengagement mechanism for facilitating disengagement from the network socket, and the disengagement mechanism includes a pressing block, a transmission elastic arm, and a fixed block which are arranged in sequence along the length direction of the upper cover and formed as one piece; the transmission elastic arm is arranged at an angle, and its lower end is connected to the fixed block, and its high end is connected to the pressing block; the pressing block and the fixed block are respectively clamped on the lower shell, and the lower end of the pressing block is provided with a pressing block inclined surface which gradually slopes downward from the direction approaching the transmission elastic arm to the direction away from the transmission elastic arm.

[0026] For a cable connector of the crystal head type, the end of the lower shell away from the locking structure is inserted into the network socket, and in order to facilitate the insertion of the crystal head type cable connector into the network socket, a disengagement mechanism is generally provided on the lower shell. When in use, the junction between the pressing block and the transmission elastic arm is pressed, and the transmission elastic arm moves downward as a whole so that the end of the lower shell can be smoothly inserted into the network socket. When the external force is removed, due to the elastic force of the pressing part and the transmission elastic arm themselves, the two can be positioned upward, so that the end of the lower shell can be tightly inserted into the network socket. By providing a pressing block inclined surface on the lower end face of the pressing block, the downward pressing space of the pressing block can be increased, so as to obtain a larger deformation displacement of the transmission elastic arm.

[0027] Furthermore, the transmission elastic arm includes an integrally formed first elastic arm and a second elastic arm, the thickness of the first elastic arm is smaller than the thickness of the second elastic arm; one end of the first elastic arm is connected to the fixed block, and a positioning block that can be inserted into the network socket is provided at the junction of the other end and the second elastic arm.

[0028] Since the force application point of the pressing block is located on the second elastic arm, the downward pressure received by the first elastic arm is transmitted from the second elastic arm. Therefore, setting the first elastic arm close to the fixed block side thinner can reduce the force required for the first elastic arm to press downward, thereby making the pressing action of the pressing block more labor-saving and convenient.

[0029] Furthermore, a bending section is provided at one end of the second elastic arm facing the pressing block, the inclination of the bending section with the horizontal plane is greater than the inclination of the second elastic arm with the horizontal plane, and the high end of the bending section is connected to the pressing block, and the low end is connected to the second elastic arm. Providing a bending section with a greater inclination near the pressing block can limit the height of the transmission elastic arm to the limited space between the fixed block and the pressing block, ensuring that the positioning block on the transmission elastic arm can be normally inserted into the network interface, and can also use the bending section to better transmit the pressing force of the pressing part to the entire transmission elastic arm, making pressing more labor-saving and easy.

[0030] Furthermore, the lower shell includes an integrally formed plug-in portion and a connecting portion, the height of the upper end surface of the connecting portion is higher than the height of the upper end surface of the plug-in portion; and the upper cover is connected to the connecting portion; the pressing block is clamped on the connecting portion, and the highest point of its upper end surface is not higher than the highest point of the upper end surface of the upper cover, so as to minimize the extra space occupied by setting the disengagement mechanism.

[0031] Furthermore, the invention also includes a line card that can move toward or away from the cable located inside the cable connector to clamp the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] 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.

[0056] Example 1

[0057] See attached Figure 1-2 As shown, a cable connector of the present invention comprises an upper cover 1 and a lower shell 2. One end of the upper cover 1 along its length direction is hinged on the lower shell 2, and the other end is buckled on the lower shell 2 through a buckling structure. The upper cover 1 and the lower shell 2 are jointly provided with a cable hole 3 for connecting a cable at one end close to the buckling structure.

[0058] The cable connector also includes a locking member for preventing the buckling structure from loosening, and the locking member includes a pressing piece 4 pressed against the buckling structure, and the pressing piece 4 is provided with a first fastener 5, a second fastener 6, and a third fastener 7 that can be buckled to the upper cover 1, the lower shell 2, and the buckling structure respectively. The first fastener 5, the second fastener 6, and the third fastener 7 can jointly prevent the pressing piece 4 from moving in three directions that are perpendicular to each other; and any one of the first fastener 5, the second fastener 6, and the third fastener 7 can at most only prevent the pressing piece 4 from moving in two perpendicular directions.

[0059] In the locking member, by pressing the pressing plate 4 against the buckling structure, a certain pressure can be applied to the buckling structure to enhance the stability of the buckling structure; and by buckling the first fastener 5, the second fastener 6, and the third fastener 7 with the upper cover 1, the lower shell 2, and the buckling structure respectively, a buckling relationship at different points can be formed between the pressing plate 4 and the upper cover 1 and the lower shell 2, and then the mutual constraints at different points can be utilized to avoid the loosening of the buckling relationship at a single point; wherein, the third fastener 7 is directly buckled on the buckling structure, which can directly enhance the buckling stability of the buckling structure; and the first fastener 5 and the second fastener 6 are buckled with the upper cover 1 and the lower shell 2 respectively, and the upper cover 1 and the lower shell 2 can be used to restrict the pressing plate 4 to ensure the stability of the position of the pressing plate 4, thereby indirectly improving the stability of the buckling structure.

[0060] In this embodiment, by limiting the limiting relationship of the first fastener 5, the second fastener 6, and the third fastener 7 on the pressing plate 4, the first fastener 5, the second fastener 6, and the third fastener 7 can cooperate with each other to form mutual constraints on the pressing plate 4 in three directions perpendicular to each other, thereby ensuring the stable constraints of the pressing plate 4 on the buckling structure; and any one of the first fastener 5, the second fastener 6, and the third fastener 7 is limited to only form a restriction on the pressing plate 4 in two vertical directions at most, so as to ensure that the first fastener 5 or the second fastener 6 can release the buckling relationship with the upper cover 1 or the lower shell 2 from the third direction that is not restricted, thereby facilitating the rapid locking or unlocking of the locking member and the cable connector. It should be noted that the three directions perpendicular to each other refer to the three directions along the length, width and height of the upper cover 1. The length, width and height directions of the lower shell 2 are consistent with the upper cover 1.

[0061] In order to facilitate understanding of the technical solution of the present invention, the buckle structure will be described in detail below. Figure 2 As shown, the buckle structure includes a buckle plate 81 and a buckle 82 which are arranged in a one-to-one correspondence. One of the buckle plate 81 and the buckle 82 is arranged on the upper cover 1, and the other is arranged on the lower shell 2. The buckle plate 81 is provided with a slot 811 for the buckle 82 to be inserted along the length direction of the upper cover. Exemplarily, the buckle plate 81 is fixedly arranged on the side of the upper cover 1 facing the lower shell 2 along the height direction of the upper cover, and the buckle 82 is correspondingly fixedly arranged on the lower shell 2. Furthermore, in order to enhance the buckling stability of the buckle structure, two buckle plates 81 are provided, and are symmetrically arranged on both sides of the cable hole 3 along the height direction of the upper cover 1. Correspondingly, two buckles 82 are also provided.

[0062] Accordingly, in some embodiments, see the attached Figure 3As shown, the pressing plate 4 includes a pressing plate body 41, on which a pressing plate 42 corresponding to the buckle plate 81 is integrally arranged, and the pressing plate 42 is pressed against the corresponding buckle plate 81, and its two sides along the height direction of the upper cover are respectively abutted against the upper cover 1 and the lower shell 2. A third fastener 7 capable of being embedded in the card slot 811 is provided on one side of each pressing plate 42 facing the corresponding buckle plate 81, and the third fastener 7 and the buckle 82 are respectively embedded in the card slot 811 from both sides of the card slot 811.

[0063] The two sides of the pressure plate 42 along the height direction of the upper cover are respectively abutted against the upper cover 1 and the lower shell 2, and the upper cover 1 and the lower shell 2 can be used to limit the pressure plate 42 along the height direction of the upper cover; then the third fastener 7 is embedded into the slot 811 to limit the third fastener 7 by using the slot 811, thereby further suppressing the limitation of the pressure plate 42 along the height direction of the upper cover. At the same time, the third fastener 7 and the buckle 82 are both embedded in the slot 811, which can enhance the clamping strength in the slot 811 and further suppress the third fastener 7 and the buckle 82 from loosening from the slot 811.

[0064] It should be noted that the pressing piece body 41 and the two pressing plates 42 form a “C”-shaped structure to ensure that the cable can smoothly enter the cable hole 3 .

[0065] Furthermore, a limiting strip 43 is provided on one side of the pressing plate 42 facing the buckling plate 81. When the third buckle 7 is inserted into the slot 811, a gap is formed between the lower shell 2 and the buckling plate 81 for the limiting strip 43 to be inserted, so as to further suppress the displacement of the pressing plate 42 along the height direction of the upper cover.

[0066] In some embodiments, see Appendix Figure 4-5 As shown, the first fastener 5 is arranged in one-to-one correspondence with the pressing plate 42 and is located on the side of the pressing plate 42 facing the upper cover 1. The upper cover 1 is provided with a first card slot 11 arranged in one-to-one correspondence with the first fastener 5 on the side facing the lower shell 2, and the first card slot 11 inhibits the corresponding first fastener 5 from moving along the length direction of the upper cover. Furthermore, the first fastener 5 is arranged on the side of the pressing plate 42 facing the cable hole 3 to prevent the first fastener 5 from occupying the external space of the cable connector.

[0067] In some embodiments, see Appendix Figure 4 As shown, a second card slot 21 is provided on one side of the lower shell 2 away from the upper cover 1, and the second fastener 6 is bent and arranged on the pressing sheet 4 and can be embedded in the second card slot 21. The second card slot 21 inhibits the second fastener 6 from moving along the length direction and width direction of the upper cover.

[0068] Since the cable is connected between the lower shell 2 and the upper cover 1, the second slot 21 is set on the side of the lower shell 2 away from the upper cover 1, which can prevent the cable from touching the engaging part of the second fastener 6 and the second slot 21 when being pulled, thereby preventing the second fastener 6 and the second slot 21 from loosening due to cable pulling, so as to utilize the engaging fixation of the second fastener 6 and the second slot 21 to ensure the stable restraint of the pressing piece 4 on the engaging structure during use.

[0069] For details, see the attached Figure 5 As shown, the second fastener 6 includes a bending plate 61 integrally provided on the pressing plate body 41, and a second buckle 62 capable of being embedded in the second clamping groove 21 is provided on the side of the bending plate 61 facing the lower shell 2. Furthermore, a clearance groove 22 for accommodating the bending plate 61 is provided on the lower shell 2. The setting of the clearance groove 22 can accommodate the bending plate 61 in the lower shell 2, so as to minimize the increase in the size of the cable connector caused by the setting of the bending plate 61.

[0070] In this embodiment, the engaging portion between the second buckle 62 and the second slot 21 is used as the unlocking position of the locking member. In order to facilitate operation, in some embodiments, a finger groove 23 connected to the second slot 21 is further provided on the side of the lower shell 2 away from the upper cover 1. The finger groove 23 is provided to facilitate the finger to be inserted into the finger groove 23 to release the engaging relationship between the second buckle 62 and the second slot 21. Furthermore, a buckle inclined surface 621 facing the finger groove 23 is provided at the lower end of the second buckle 62. This allows the hand to directly apply force on the buckle inclined surface 621, so as to save effort when unlocking.

[0071] In order to minimize the size change of the cable connector caused by the setting of the locking piece, in some embodiments, the upper cover 1 and the lower shell 2 are jointly provided with a pressing piece receiving groove for accommodating the pressing piece 4 along one end of the length direction, so that when the pressing piece 4 is located in the pressing piece receiving groove, one side can be pressed against the snap-fit ​​plate 81, and the other side will not protrude from the upper cover 1 or the lower shell 2.

[0072] The working process of the locking member of this embodiment is as follows:

[0073] When the buckle 82 is buckled onto the buckle plate 81, force is applied to embed the first buckle 5 into the first slot 11 along the height direction of the upper cover 1; then force is applied along the length direction of the upper cover 1 to embed the third buckle 7 into the slot 811, and the limiting insert 43 is then inserted into the gap between the lower shell 2 and the buckle plate 81. At this time, the bending plate 61 can be placed in the clearance slot 22; the bending plate 61 is pressed upward along the height direction of the upper cover to embed the second buckle 62 into the second slot 21, and the locking action of the locking member is completed;

[0074] When unlocking is required, a finger is inserted into the finger groove 23 and the second buckle 62 is pushed outward to loosen the second buckle 62 from the second slot 21; then the bending plate 61 is pushed along the length direction of the upper cover to make the bending plate 61 drive the pressing piece 4 to move, and the third fastener 7 is immediately disengaged from the slot 811; then the pressing piece 4 is pulled downward along the height direction of the upper cover to disengage the first fastener 5 from the first slot 11. At this time, the unlocking action of the locking member is completed, and the buckle 82 can be disengaged from the slot 811.

[0075] It should be noted that the cable connector of this embodiment can be either a network module type connector or a crystal head type connector.

[0076] Example 2

[0077] See attached Figure 6 As shown, a cable connector of this embodiment includes an upper cover 1 and a lower shell 2. One end of the upper cover 1 along its length direction is hinged on the lower shell 2, and the other end is buckled on the lower shell 2 through a buckle structure. The upper cover 1 and the lower shell 2 are jointly provided with a cable hole 3 for connecting a cable at one end close to the buckle structure. The cable connector also includes a locking member for preventing the buckle structure from loosening, wherein the locking member can refer to Example 1, and this embodiment focuses on describing the structure of the upper cover 1 and the lower shell 2.

[0078] In some embodiments, see Appendix Figure 7-8 As shown, the lower shell 2 includes an integrally formed plug-in portion 24 and a connecting portion 25, and the upper end surface height of the connecting portion 25 is higher than the upper end surface height of the plug-in portion 24. A pair of hinge seats 251 are arranged along the width direction of the connecting portion 25 on one side close to the plug-in portion 24, and the upper cover 1 is covered on the connecting portion 25, and a notch is opened on the side facing the plug-in portion 24, and two connecting arms 12 are formed on both sides of the notch, and the two connecting arms 12 are respectively hinged to the hinge seats 251, so as to realize the upper cover 1 to swing up and down relative to the lower shell 2.

[0079] An accommodating chamber is defined between the upper cover 1 and the connecting portion 25 , in which a linking function core 9 is disposed. One end of the linking function core 9 is fixedly connected to the cable inserted into the cable hole 3 , and the other end extends into the plug-in portion 24 .

[0080] In some embodiments, a line card 10 is also included that can move toward or away from the cable inside the cable connector, and the line card 10 can reciprocate along an axis perpendicular to the cable. When the line card 10 moves toward the cable, it can engage with the link function core 9 to compress the cable.

[0081] See attached Figure 9-10As shown, the line card 10 includes a flat substrate 101, an arc-shaped positioning edge 102 is arranged on the side of the substrate 101 close to the cable, at least one substrate card slot 103 is arranged on the end face of the substrate 101 close to the link function core 9, and at least one engaging protrusion 91 that can cooperate with the substrate card slot 103 is arranged on the link function core 9. After the lower shell 2 is buckled with the upper cover 1, the line card 10 is pushed to move toward the cable, and the engaging protrusion 91 is inserted into the substrate card slot 103 to realize the positioning of the cable.

[0082] In some embodiments, an opening 13 is provided on the upper cover 1, which is connected to the accommodating chamber and corresponds to the position of the line card 10. A force can be applied to the line card 10 through the opening 13 to enable the line card 10 to move toward the cable direction and engage with the link function core 9, thereby compressing the cable.

[0083] By setting the line card 10 and adding a snap-fit ​​protrusion 91 on the link function core 9 to cooperate with the substrate slot 103 on the line card 10, the substrate slot 103 cooperates with the snap-fit ​​protrusion 91 to achieve the snap-fit ​​between the line card 10 and the link function core 9. The line card 10 is located inside the cable connector, and there is no need to separately set a clamp structure for tying the wires at the outer end of the cable connector, thereby making the overall length of the cable connector smaller. Moreover, the link function core 9 is a structure that is originally set in the cable connector in conventional technology, so the length of the cable connector will not be significantly changed due to the setting of a snap-fit ​​protrusion 91.

[0084] Example 3

[0085] For a cable connector such as a plug, the end of the lower shell 2 away from the engaging structure is inserted into the network socket, and in order to facilitate the insertion of the plug-type cable connector into the network socket, a disengagement mechanism is generally provided on the lower shell 2. Based on this, this embodiment is based on Embodiment 2, and a disengagement mechanism is added to the lower shell 2 to facilitate disengagement from the network socket.

[0086] For details, see the attached Fig.11 As shown, the disengagement mechanism includes a pressing block 26, a transmission elastic arm 27, and a fixing block 28 which are arranged in sequence along the length direction of the upper cover and are integrally formed; the fixing block 28 is clamped on the plug-in portion 24, and the pressing block 26 is clamped on the connecting portion 25 and is located at the notch of the upper cover 1. The transmission elastic arm 27 is arranged obliquely, with its lower end connected to the fixing block 28 and its higher end connected to the pressing block 26.

[0087] In this embodiment, the fixing block 28 is clamped on the plug-in portion 24, and the pressing block 26 is clamped on the connecting portion 25 and is located at the notch of the upper cover 1. A pressing space is reserved between the pressing block 26 and the connecting portion 25 for the pressing block 26 to move downward. When in use, the junction between the pressing block 26 and the transmission elastic arm 27 is pressed, and the transmission elastic arm 27 moves downward as a whole so that the plug-in portion 24 can be smoothly inserted into the network socket. When the external force is removed, due to the elastic force of the pressing block 26 and the transmission elastic arm 27 themselves, the two can be limited upward, so that the lower plug-in portion 24 can be tightly inserted into the network socket.

[0088] In some embodiments, see Appendix Figure 11-12 As shown, the lower end of the pressing block 26 is provided with a pressing block inclined surface 261 which gradually slopes downward from the direction close to the transmission elastic arm 27 to the direction away from the transmission elastic arm 27. By providing the pressing block inclined surface 261 on the lower end surface of the pressing block 26, the downward pressing space of the pressing block 26 can be increased, so that the transmission elastic arm 27 can obtain a larger deformation displacement. And the high end of the pressing block inclined surface 261 is connected to the high end of the transmission elastic arm 27, so that the connection between the pressing block 26 and the transmission elastic arm 27 forms a commanding height. When pressed by external force, the commanding height can quickly deform to store force for the upward reset of the pressing block 26.

[0089] In some embodiments, the upper end surface of the pressing block 26 is a plane, and a boss 262 protruding upward is provided at the connection between the pressing block 26 and the transmission elastic arm 27, and the boss 262 provides a force point for finger pressing. Furthermore, the highest point of the boss 262 is not higher than the highest point of the upper end surface of the upper cover 1, so as to minimize the additional space occupied by the disengagement mechanism.

[0090] In some embodiments, the transmission elastic arm 27 includes an integrally formed first elastic arm 271 and a second elastic arm 272, wherein the thickness of the first elastic arm 271 is smaller than the thickness of the second elastic arm 272; one end of the first elastic arm 271 is connected to the fixing block 28, and a positioning block 273 that can be inserted into the network socket is provided at the junction of the other end and the second elastic arm 272.

[0091] The pressing block 26 is pressed downward, and the second elastic arm 272 moves downward under the action of the pressing block 26, and the first elastic arm 271 can move downward accordingly and drive the positioning block 273 to move downward, so that the plug-in portion 24 can smoothly enter the network socket. At this time, the first elastic arm 271 and the positioning block 273 can both be located in the network socket. When the external force applied to the pressing block 26 is released, the first elastic arm 271 and the second elastic arm 272 rebound and reset, and the positioning block 273 can move upward and reset accordingly, and then be clamped in the network socket.

[0092] Since the force application point of the pressing block 26 is located on the second elastic arm 272, the downward pressure received by the first elastic arm 271 is transmitted from the second elastic arm 272. Therefore, setting the first elastic arm 271 close to the side of the fixed block 28 to be thinner can reduce the force required for the first elastic arm 271 to press downward, thereby making the pressing action of the pressing block 26 more labor-saving and convenient.

[0093] For further information, see Appendix Fig.11 As shown, a bending section 274 is provided at one end of the second elastic arm 272 facing the pressing block 26, and the inclination of the bending section 274 with the horizontal plane is greater than that of the second elastic arm 272 with the horizontal plane, and the high end of the bending section 274 is connected to the high end of the pressing block inclined surface 261, and the low end is connected to the second elastic arm 272. The bending section 274 with a greater inclination is provided near the pressing block 26, so that the height of the transmission elastic arm 27 can be limited to the limited space between the fixing block 28 and the pressing block 26, ensuring that the positioning block 273 on the transmission elastic arm 27 can be normally inserted into the network interface, and the bending section 274 can be used to better transmit the pressing force of the pressing block 26 to the entire transmission elastic arm 27, making the pressing more labor-saving and easy.

[0094] Furthermore, the intersection of the bending section 274 and the second elastic arm 272 forms a lower bending point 275, and the intersection of the pressing block inclined surface 261 and the bending section 274 forms a bending angle 263. When the boss 262 is pressed downward, the intersection of the pressing block inclined surface 261 and the bending section 274 is deformed downward, and the degree of the bending angle 263 is increased to drive the bending section 274 to move downward, and then the downward movement of the lower bending point 275 drives the high end of the second elastic arm 272 to deform downward until the positioning block 273 moves down to a height that can be inserted into the network socket. Compared with the prior art in which the force application point is set at the end of the transmission elastic arm close to the network socket, which results in limited space for downward deformation and difficulty in applying force, the present embodiment concentrates the force application point and the downward deformation position at the end of the transmission elastic arm away from the network socket (the downward deformation position is concentrated on the high end of the second elastic arm 272, the bending section 274 and the pressing block 26), and then transmits the downward force to the positioning block 273 at the end close to the network socket through the action of the force arm, making the entire downward action more labor-saving and easy.
