Description

Technical Field

[0001] The utility model relates to the technical field of cable connection, in particular to a cable connector, a network module connector and a crystal head connector. 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, the cable will exert a force on the engagement part of the second slot and the second buckle, which may 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.

[0004] Therefore, it is necessary to provide a clamping structure for a cable connector, a network module connector and a crystal head connector to solve the above problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the utility model is to provide a clamping structure for a cable connector, a network module connector and a crystal head connector, 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 connector.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a clamping structure for a cable connector, the cable connector includes a connector housing, the connector housing includes an upper cover and a lower shell that can be buckled up and down, and the upper cover and the lower shell are both provided with a clearance hole for cable insertion. When buckled, a receiving space for cable insertion is formed between the upper cover and the lower shell. The clamping structure includes a clamping structure 1 and a clamping structure 2 respectively arranged on the upper cover and the lower shell, the clamping structure 1 includes at least one group of first clamping grooves and first clamping protrusions, the clamping structure 2 includes at least one group of second clamping grooves and second clamping protrusions, the first clamping groove of the clamping structure 1 and the second clamping protrusion of the clamping structure 2 can be mutually engaged, and the first clamping protrusion of the clamping structure 1 and the second clamping groove of the clamping structure 2 can be mutually engaged.

[0008] Furthermore, the first engaging protrusion and the second engaging protrusion have the same structure, the second engaging protrusion is arranged in the opposite direction to the first engaging protrusion, and the second engaging protrusion is inverted on the surface of the lower shell.

[0009] Furthermore, a first locking slot setting arm is extended from the lower surface of the upper cover toward the lower shell, and a second locking slot setting arm is extended from the upper surface of the lower shell toward the upper cover. The first locking slot and the second locking slot are respectively provided on the first locking slot setting arm and the second locking slot setting arm. The side opposite to the first locking slot setting arm and the second locking slot setting arm are jointly surrounded by the clearance hole to form a limited space for the cable to be inserted, wherein the clearance holes located on the upper cover and the lower shell can position the cable in the vertical direction, while the first locking slot setting arm and the second locking slot setting arm located on the left and right sides can position the cable in the horizontal direction, further ensuring the stability of the connection between the cable and the cable connector.

[0010] Furthermore, a plurality of limiting protrusions are provided on the upper surface of the clearance hole on the lower shell, and a first clamping protrusion and a second clamping protrusion are provided on the upper cover and the lower shell, respectively, and a groove is provided at the second clamping protrusion, which is recessed in a direction away from the cable inlet. The plurality of limiting protrusions can increase the contact area between the clearance hole on the lower shell and the cable, thereby ensuring that the cable is clamped tightly.

[0011] A network module connector also includes a connecting part, wherein the upper cover and the lower shell tail are respectively hinged to the upper and lower surfaces of the connecting part, and when the upper cover and the lower shell are buckled, a limited space for the connection function core, the line card and the line pressure cover is formed between the connector shell and the connecting part. One end of the connecting part away from the cable connector can be used for plug-in insertion and connection, and the connection part is combined with the cable connector to ensure the stability of the signal between the cable and the plug-in during the use of the network module connector.

[0012] Furthermore, the line card includes a vertically arranged base, a curved edge is arranged on the protruding line card surface on one side of the base close to the cable, a plurality of limit ridges corresponding to the position of the limit protrusions are arranged on the lower surface of the curved edge, a plurality of card slots are arranged horizontally from top to bottom on one side of the line card close to the connection part, and a card block matching the card slot is protrudingly arranged on the line pressing cover. After the cable is inserted into the clearance hole, the line card is pushed in the direction toward the cable so that the card block on the line pressing cover can be inserted into the corresponding card slot, and the cable is further compressed between the upper cover and the lower shell.

[0013] A RJ45 connector further includes a plugging part that can be inserted into a socket. The tail of the upper cover is hinged to the tail of the upper surface of the lower shell. The outer shell of the plugging part is integrally formed with the lower shell, and a disengaging mechanism is arranged on the upper surface of the plugging part. For a RJ45 connector, the plugging part thereof is inserted into the socket on a network module connector. In order to facilitate plugging, a disengaging mechanism is generally arranged on the lower shell.

[0014] Furthermore, the disengaging mechanism includes a pressing block, a transmission spring arm, and a fixing block that are arranged in sequence along the length direction of the plugging part and integrally formed. The transmission spring arm is arranged obliquely, with its lower end connected to the fixing block and its upper end connected to the pressing block. The pressing block and the fixing block are respectively clamped on the plugging part, and the fixing block is clamped on the plugging part, while the pressing block is clamped on the connector shell and located at the notch of the upper cover. During use, when pressing the junction of the pressing block and the transmission spring arm, the whole transmission spring arm moves downward so that the plugging part can be smoothly inserted into the socket of the network module connector. When the external force is withdrawn, due to the elastic force of the pressing block and the transmission spring arm itself, the two can be limited upward, enabling the lower plugging part to be tightly inserted into the socket of the network module connector.

[0015] And a pressing block inclined surface that gradually slopes downward towards the transmission spring arm and away from the transmission spring arm is provided at the lower end of the pressing block. By providing the pressing block inclined surface on the lower end surface of the pressing block, the pressing space of the pressing block downward can be increased, so as to facilitate the transmission spring arm to obtain a larger deformation displacement.

[0016] The transmission spring arm includes a first spring arm and a second spring arm that are integrally formed. The thickness of the first spring arm is less than that of the second spring arm. One end of the first spring arm is connected to the fixing 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 spring arm.

[0017] Furthermore, a bent section is provided at one end of the second spring arm facing the pressing block. The inclination of the bent section with respect to the horizontal plane is greater than that of the second spring arm with respect to the horizontal plane, and the upper end of the bent section is connected to the pressing block and the lower end is connected to the second spring arm.

[0018] By providing a bent section with a greater inclination near the pressing block, the height of the transmission spring arm can be limited within the limited space between the fixing block and the pressing block, ensuring that the positioning block on the transmission spring arm can be normally inserted into the connecting part on the network module connector, and at the same time, the pressing force of the pressing block can be better transmitted to the entire transmission spring arm by using the bent section, making the pressing more labor-saving and easier.

[0019] The beneficial effects of the present utility model:

[0020] In the present utility model, engaging structures I and II are respectively provided on the upper cover and the lower housing. Among them, the first engaging grooves, the first engaging protrusions on the upper cover correspond to the second engaging protrusions and the second engaging grooves on the lower housing one by one. It can ensure that no matter which direction the cable is pulled or bent, on both sides of the relief hole, there is one side that can offset the upward or downward force formed by the cable at the engaging part, thereby ensuring that the engaging protrusions will never disengage from the engaging grooves, and ensuring the stable connection between the cable and the cable connector. In this application, by setting the second engaging protrusion and the first engaging protrusion in opposite directions, thus, the first engaging protrusion and the second engaging protrusion can present an interleaved setting effect, so that the upper cover and the lower housing can achieve a perfect engaging effect at any angle, and there will be no situation that is prone to unlocking or disengaging when the cable is pulled in the opposite direction of the engagement as in the prior art.

[0042] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a more clear and definite definition of the protection scope of the present utility model.

[0043] Referring to the attached Figures 1 to 3 As shown, a clamping structure for a cable connector in this embodiment, the cable connector includes a connector housing 1, the connector housing 1 includes an upper cover 11 and a lower shell 12 that can be buckled up and down, and relief holes 10 for inserting the cable are provided on both the upper cover 11 and the lower shell 12. When buckled, a receiving space for inserting the cable is formed between the upper cover 11 and the lower shell 12, and the relief holes 10 on the upper cover 11 and the lower shell 12 can enclose a complete through hole for inserting the cable after the two are buckled.

[0044] The snap - fit structure includes a first snap - fit structure and a second snap - fit structure respectively arranged on the upper cover 11 and the lower shell 12. The first snap - fit structure includes at least one group of first snap - fit grooves 2 and first snap - fit protrusions 3. The second snap - fit structure includes at least one group of second snap - fit grooves 4 and second snap - fit protrusions 5. The first snap - fit groove 2 of the first snap - fit structure can be snap - fitted with the second snap - fit protrusion 5 of the second snap - fit structure, and the first snap - fit protrusion 3 of the first snap - fit structure can be snap - fitted with the second snap - fit groove 4 of the second snap - fit structure. After the two are snap - fastened, it can prevent the upper cover 11 and the lower cover from loosening.

[0045] The first snap - fit grooves 2 and first snap - fit protrusions 3 respectively arranged on both sides of the relief hole 10 on the upper cover 11 correspond one - to - one with the second snap - fit protrusions 5 and second snap - fit grooves 4 respectively arranged on both sides of the relief hole on the lower shell 12. When snap - fastening, the second snap - fit protrusion 5 snaps into the corresponding first snap - fit groove 2, and the first snap - fit protrusion 3 snaps into the corresponding second snap - fit groove 4. That is, whether it is the upper cover 11 or the lower shell 12, there will be no single snap - fit groove or snap - fit protrusion that can make the upper cover 11 and the lower shell 12 snap - fit at the same height in the vertical direction on both sides of the relief hole.

[0046] For specific details, please refer to the appendix Figure 1 A first snap - fit groove 2 is provided at the lower part of the left end of the upper cover 11, and first snap - fit protrusions 3 are arranged at the right end. A second snap - fit protrusion 5 corresponding to the first snap - fit groove 2 is arranged at the upper part of the left end of the lower shell 12, and a second snap - fit groove 4 corresponding to the first snap - fit protrusion 3 is provided at the right end. When the upper cover 11 and the lower shell 12 are snap - fastened, the second snap - fit protrusion 5 snaps into the first snap - fit groove 2, and the first snap - fit protrusion 3 snaps into the second snap - fit groove 4;

[0047] When pulling the cable upward, the upper surface of the first snap - fit protrusion 3 on the upper cover 11 abuts against the upper surface of the second snap - fit groove 4 on the lower shell 12. The second snap - fit groove 4 snaps onto the first snap - fit protrusion 3. When pulling the cable, the second snap - fit groove 4 can exert a downward force on it, thereby offsetting the upward force applied at the snap - fit point when pulling the cable, so as to prevent the upper cover 11 and the lower shell 12 from separating;

[0048] When pulling the cable downward, the lower surface of the second snap - fit protrusion 5 on the lower shell 12 abuts against the lower surface of the first snap - fit groove 2 on the upper cover 11. The first snap - fit groove 2 snaps onto the second snap - fit protrusion 5. When pulling the cable downward, it can exert an upward force on the second snap - fit protrusion 5, thereby offsetting the downward force applied at the snap - fit point, thus ensuring that the upper cover 11 and the lower shell 12 will not separate and ensuring the stability of the snap - fit.

[0049] Therefore, compared with the prior art in which only one of the engaging grooves or engaging protrusions is provided on the upper cover 11 and the lower case 12 respectively, when pulling the cable in the opposite direction of the engagement along the engaging groove or the engaging protrusion, the cable will exert a force on the engaging part of the engaging groove or the engaging protrusion, causing the loosening of the engaging part (the engaging groove disengaging from the engaging protrusion). In contrast, when a set of engaging grooves and engaging protrusions are respectively provided on the upper cover 11 or the lower case 12, it can be ensured that when the cable is pulled upward or downward, on both sides of the relief hole, there is one side that can offset the upward or downward force formed by the cable at the engaging part, thereby ensuring that the engaging protrusion will never disengage from the engaging groove and ensuring the stable connection between the cable and the cable connector.

[0050] In some embodiments, the number of the first engaging grooves 2 or the first engaging protrusions 3 provided on the upper cover 11 on one side of the relief hole 10 can also be 2, 3, etc. A plurality of the first engaging grooves 2 or the first engaging protrusions 3 are sequentially arranged along the height direction of the upper cover 11. Correspondingly, the number and positions of the second engaging protrusions 5 or the second engaging grooves 4 provided on the lower case 12 correspond one by one to those of the first engaging grooves 2 or the first engaging protrusions 3, further ensuring the stability when the cable is connected to the cable connector. When the cable is pulled unidirectionally, the upper cover 11 and the lower case 12 are not easily separated.

[0051] It should be noted that the plurality of the first engaging grooves 2 or the first engaging protrusions 3 here can be arranged in an array along the height direction of the upper cover 11.

[0052] See the appendix Figures 2 to 3 , the first engaging protrusion 3 includes a bearing surface 31 and a protruding inclined surface 32. The bearing surface 31 is parallel to the upper surface of the upper cover 11, and one end of the protruding inclined surface 32 far from the bearing surface 31 is inclined towards the direction close to the upper cover 11. Specifically, the first engaging protrusion 3 has a vertical direct trapezoidal structure, and the bearing surface 31 is a horizontal plane connecting two parallel surfaces on the right trapezoid, ensuring the contact area between the bearing surface 31 and the second engaging groove 4, so that when the cable is pulled upward, the second engaging groove 4 can exert a downward acting force on the first engaging protrusion 3 sufficient to ensure that the upper cover 11 and the lower case 12 will not separate.

[0053] It should be noted that the structures and sizes of the first engaging groove 2 and the second engaging groove 4 are not fixed, as long as they can cooperate with the first engaging protrusion 3 and the second engaging protrusion 5 to firmly clamp the upper cover 11 and the lower cover.

[0054] The first engaging protrusion 3 has the same structure as the second engaging protrusion 5, and the second engaging protrusion is arranged in the opposite direction to the first engaging protrusion.

[0055] In some embodiments, the opposite arrangement direction here is reflected in that, firstly, the bearing surface of the first engaging protrusion is close to the upper surface of the upper cover, while the corresponding second engaging protrusion 5 is inverted on the surface of the lower case 12, and the bearing surface thereon is close to the lower surface of the lower case;

[0056] Secondly, the first engaging protrusion is arranged at the right end of the upper cover, and the second engaging protrusion is arranged at the left end of the lower cover, so that the first engaging protrusion and the second engaging protrusion correspond to the second engaging groove and the first engaging groove on the lower cover and the upper cover respectively. Therefore, the first engaging protrusion and the second engaging protrusion can be arranged alternately on both sides of the clearance hole. Thus, the upper cover and the lower shell can achieve a perfect buckling effect at any angle.

[0057] A first engaging slot setting arm is extended from the lower surface of the upper cover 11 toward the lower shell 12, and a second engaging slot setting arm is extended from the upper surface of the lower shell 12 toward the upper cover 11. The first engaging slot 2 and the second engaging slot 4 are respectively provided on the first engaging slot setting arm 17 and the second engaging slot setting arm 18. The side opposite to the first engaging slot setting arm and the second engaging slot setting arm is jointly surrounded by the clearance hole 10 to form a limited space for the cable to be inserted, wherein the clearance hole 10 located on the upper cover 11 and the lower shell 12 can position the cable in the vertical direction, while the first engaging slot setting arm and the second engaging slot setting arm located on the left and right sides can position the cable in the horizontal direction, further ensuring the stability of the connection between the cable and the cable connector.

[0058] The upper surface of the clearance hole 10 on the lower shell 12 is provided with a plurality of limiting protrusions, and the first and second clamping protrusions on the upper cover and the lower shell are provided with grooves that are recessed in the direction away from the cable inlet. The plurality of limiting protrusions can increase the contact area between the clearance hole 10 on the lower shell 12 and the cable, ensuring that the cable is clamped tightly. By providing the groove to make way for the second clamping groove and the first clamping groove when the first and second clamping protrusions are engaged, the side of the connector housing facing the cable entry direction after the clamping is a flat plane, making the overall structure of the cable connector more beautiful.

[0059] See attached Figures 4 to 6 , 10 to 11, a network module connector, further comprising a connecting portion 7, wherein the tails of the upper cover 11 and the lower shell 12 are respectively hinged to the upper and lower surfaces of the connecting portion 7, and when the upper cover 11 and the lower shell 12 are buckled, a limited space for the connection function core 8, the line card 9 and the crimping cover 13 is formed between the connector housing 1 and the connecting portion 7. One end of the connecting portion 7 away from the cable connector can be used for plug-in insertion and connection, and the connection portion 7 is combined with the cable connector to ensure the stability of the signal between the cable and the plug-in during the use of the network module connector 15.

[0060] In some embodiments, see Appendix Figure 4, an opening is provided at the top of the upper cover 11. Notches are provided on the upper surface of the upper cover 11 and the tail of the lower surface of the lower cover. Connecting arms are formed on both sides of the notches. An articulated seat is provided between the two connecting arms at the top. The upper cover 11 is articulated to the connecting part 7 through this articulated seat. Clamping blocks are provided on the two connecting arms at the bottom, and are articulated to the lower surface of the connecting part 7 through these clamping blocks.

[0061] See attached Figures 5 to 6 , the wire clip 9 includes a vertically arranged base 91. When the wire clip 9 is arranged, the plane where the height direction of the base 91 is located is perpendicular to the upper surface of the upper cover 11. The top of the wire clip 9 is located within the opening on the upper cover 11;

[0062] An arc-shaped edge 92 is provided on the side of the base 91 close to the cable, protruding from the surface of the wire clip 9. The arc structure of the arc-shaped edge 92 matches the relief hole 10 and will not interfere with the insertion of the cable into the connector housing 1;

[0063] A plurality of limiting ribs 93 corresponding to the positions of the limiting protrusions are provided on the lower surface of the arc-shaped edge 92. The plurality of limiting ribs 93 correspond to the positions of the limiting protrusions, which can increase the contact area between the arc-shaped edge 92 and the cable after the cable is inserted, thereby ensuring the clamping of the cable.

[0064] A plurality of card slots 94 are horizontally arranged from top to bottom on the side of the wire clip 9 close to the connecting part 7. A card block matching the card slots 94 is prominently provided on the pressing cover 13. After the cable is inserted into the relief hole 10, the wire clip 9 is pushed towards the cable, so that the card block on the pressing cover 13 can be inserted into the corresponding card slot 94. At this time, the cable is further pressed between the upper cover 11 and the lower housing 12.

[0065] See attached Figures 7 to 9 , a RJ45 connector further includes a plugging part 6 that can be inserted into the socket. The tail of the upper cover 11 is articulated to the tail of the upper surface of the lower housing 12. The outer housing of the plugging part 6 is integrally formed with the lower housing 12. A detachment mechanism 16 is provided on the upper surface of the plugging part 6. For the RJ45 connector 14, the plugging part 6 on it is inserted into the socket of the network module connector 15. In order to facilitate the plugging, a detachment mechanism 16 is generally provided on the lower housing 12.

[0066] See attached Figures 8 to 9, the detachment mechanism 16 includes a pressing block 161, a transmission elastic arm 162, and a fixing block 163 that are arranged in sequence along the length direction of the insertion part 6 and integrally formed. The transmission elastic arm 162 is arranged obliquely, with its lower end connected to the fixing block 163 and its upper end connected to the pressing block 161; the pressing block 161 and the fixing block 163 are respectively clamped on the insertion part 6, the fixing block 163 is clamped on the insertion part 6, and the pressing block 161 is clamped on the connector housing 1 and is located at the notch of the upper cover 11. During use, when pressing at the junction of the pressing block 161 and the transmission elastic arm 162, the whole transmission elastic arm 162 moves downward so that the insertion part 6 can be smoothly inserted into the socket of the network module connector 15. When the external force is withdrawn, due to the elastic force of the pressing block 161 and the transmission elastic arm 162 themselves, the two can be limited upward, so that the lower insertion part 6 can be tightly inserted into the socket of the network module connector 15.

[0067] And the lower end of the pressing block 161 is provided with a pressing block inclined surface 164 that slopes downward gradually in the direction away from the transmission elastic arm 162. By setting the pressing block inclined surface 164 on the lower end surface of the pressing block 161, the pressing space of the pressing block 161 downward can be increased, so as to facilitate the transmission elastic arm 162 to obtain a larger deformation displacement;

[0068] The transmission elastic arm 162 includes a first elastic arm 166 and a second elastic arm 167 that are integrally formed. The thickness of the first elastic arm 166 is less than the thickness of the second elastic arm 167; one end of the first elastic arm 166 is connected to the fixing block 163, and a positioning block 168 that can be inserted into the network socket is provided at the junction of the other end and the second elastic arm 167.

[0069] In some embodiments, the upper end surface of the pressing block 161 is a plane, and a convex platform 165 that protrudes upward is provided at the connection with the transmission elastic arm 162. The convex platform 165 provides a force application point for finger pressing. Further, the highest point of the convex platform 165 is not higher than the highest point of the upper end surface of the upper cover 11, so as to minimize the additional space occupied due to the setting of the detachment mechanism 16.

[0070] See attached Figures 8 to 9 , one end of the second elastic arm 167 facing the pressing block 161 is provided with a bent section 169. The inclination of the bent section 169 with respect to the horizontal plane is greater than the inclination of the second elastic arm 167 with respect to the horizontal plane, and the upper end of the bent section is connected to the pressing block 161 and the lower end is connected to the second elastic arm 167.

[0071] A bending section 169 with a greater inclination is provided near the pressing block 161, which can limit the height of the transmission spring arm 162 within the limited space between the fixing block 163 and the pressing block 161, ensuring that the positioning block 168 on the transmission spring arm 162 can be normally inserted into the connecting part 7 on the network module connector 15. Moreover, the pressing force of the pressing block 161 can be better transmitted to the entire transmission spring arm 162 through the bending section 169, making the pressing more labor-saving and easier.

[0072] A downward bending point 170 is formed at the junction of the bending section 169 and the second spring arm 167, and a bending angle 171 is formed at the junction of the pressing block inclined surface 164 and the bending section 169. When the convex platform 165 is pressed downward, the junction of the pressing block inclined surface 164 and the bending section 169 deforms downward immediately, and the degree of the bending angle 171 increases immediately, so as to drive the bending section 169 to move downward. Then, the downward movement of the downward bending point 170 drives the upper end of the second spring arm 167 to deform downward until the positioning block 168 moves downward to a height where it can be inserted into the network socket. Compared with the prior art in which the force application point is set at one end of the transmission spring arm close to the network socket, resulting in limited downward deformation space and difficult force application, in this embodiment, the force application point and the downward pressing deformation position are concentrated at one end of the transmission spring arm far from the network socket (the downward pressing deformation position is concentrated on the upper end of the second spring arm 167, the bending section 169 and the pressing block 161), and then the downward pressure is transmitted to the positioning block 168 at one end close to the network socket through the lever action, making the entire downward pressing action more labor-saving and easier.
