Description
Technical Field
[0001] This utility model relates to the field of connector plug technology, specifically a modular connector plug. Background Technology
[0002] Modular connector plugs are core components in electronic devices that enable circuit connections. Their shape must match the matching socket to ensure compatibility, so their shape and structure are usually relatively fixed. However, the contact springs of existing modular connector plugs are mostly directly snapped into the shell without a dedicated anti-dislodgement positioning structure. Under long-term insertion and removal or vibration, the springs are prone to displacement and loosening, resulting in poor contact. Utility Model Content
[0003] The purpose of this invention is to provide a modular connector plug to solve the problems mentioned in the background art.
[0004] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0005] A modular connector plug includes a connecting block and a pair of conductive plates. One side of the connecting block has a pair of openings, and the connecting block has a cavity on the side opposite to the openings. A pair of partition blocks are installed within the cavity, with one side of each partition block located within the pair of openings, dividing the openings into three parts: a first limiting groove, a second limiting groove, and a third limiting groove. The first limiting groove, the second limiting groove, and the third limiting groove form a U-shape. Each partition block has a slot, which communicates with the second limiting groove. An arc-shaped piece and a positioning piece are installed on the side of each conductive plate. The conductive plate is located within the slot and the second limiting groove. The free end of the conductive plate is located within the connecting block. On the outside of the connector block, the arc-shaped piece is in the first limiting groove, and the bent part of the arc-shaped piece abuts against the partition block. The positioning piece is in the third limiting groove. The partition block divides the opening of the connector block into a U-shaped first limiting groove, a second limiting groove, and a third limiting groove, which respectively cooperate with the arc-shaped piece and the positioning piece on the conductive piece. The arc-shaped piece abuts against the partition block in the first limiting groove, and the positioning piece is embedded in the third limiting groove. The main body of the conductive piece is placed in the opening and the second limiting groove, which forms limiting constraints on the conductive piece from different directions, restricting the displacement space of the conductive piece in the horizontal and vertical directions, thereby preventing the conductive piece from shifting or loosening, and ensuring the stability of the contact between the conductive piece and the matching socket.
[0006] Furthermore, a pair of threaded sleeves are installed on the wall of the cavity near a pair of partition blocks. A pair of fixing blocks are provided inside the cavity. The fixing blocks have through holes, and the threaded sleeves can slide within the through holes. A screw also slides within the through holes. The screw and the threaded sleeve are engaged. The screw head abuts against the fixing block. The fixing block abuts against the bent end of the arc-shaped piece. The threaded sleeve on the cavity wall of the connecting block slides in conjunction with the through hole of the fixing block. The screw passes through the through hole and engages with the threaded sleeve. The screw head abuts against the fixing block. The fixing block abuts against the bent end of the arc-shaped piece. By turning the screw, the fixing block can be pushed towards the arc-shaped piece, thereby applying a continuous clamping force to the arc-shaped piece. Combined with the limiting effect of the partition blocks on the arc-shaped piece, the fixing effect on the conductive piece is further enhanced, preventing the conductive piece from loosening under long-term insertion and removal or vibration.
[0007] Furthermore, the surface of the fixing block has a countersunk hole, which is coaxially connected to the through hole. The screw head is located inside the countersunk hole and has a regular hexagonal groove. The countersunk hole and the through hole on the fixing block are coaxially arranged, and the screw head is placed inside the countersunk hole, so that the screw head will not protrude from the surface of the fixing block, avoiding interference between the screw head and other components in the cavity. At the same time, the regular hexagonal groove of the screw head cooperates with the matching hexagonal wrench, making it easy for operators to tighten the screw, thus improving the convenience of installing and removing the fixing block.
[0008] Furthermore, both the separator and the fixing block are made of insulating material. When the separator and the fixing block are made of insulating material, they cooperate with the conductive sheet, the arc-shaped sheet and the positioning sheet to effectively block the conduction of current between each conductive component and the connecting block, avoid short circuits, and prevent electric shock hazards to operators when touching the connector plug, thereby improving the safety of the connector plug.
[0009] Furthermore, the end face of the separator block located within the cavity is an arc surface, and the arc degree is the same as the inner arc degree of the arc-shaped piece. The end face of the separator block located within the cavity is designed to be an arc surface with the same inner arc degree as the arc-shaped piece, which cooperates with the bending part of the arc-shaped piece, increasing the contact area between the separator block and the arc-shaped piece. This allows the bending part of the arc-shaped piece to fit more closely against the end face of the separator block, dispersing the pressure of the arc-shaped piece on the separator block. At the same time, it makes the limiting of the separator block on the arc-shaped piece more stable, preventing the arc-shaped piece from deforming due to excessive local stress.
[0010] Furthermore, the positioning piece is a rectangular sheet structure, and the end of the positioning piece away from the conductive sheet is provided with anti-slip protrusions. The anti-slip protrusions fit into the inner wall of the third limiting groove. The rectangular sheet structure of the positioning piece increases the contact area with the inner wall of the third limiting groove. At the same time, the anti-slip protrusions at the end of the positioning piece fit into the inner wall of the third limiting groove, increasing the friction between the positioning piece and the third limiting groove. This effectively prevents the positioning piece from sliding in the third limiting groove, further enhancing the positioning effect on the conductive sheet and preventing the conductive sheet from shifting.
[0011] Furthermore, the surface of the free end of the conductive sheet is gold-plated. Gold plating of the free end of the conductive sheet has excellent conductivity and oxidation resistance. When combined with the contact components of the matching socket, it can reduce the contact resistance when the free end of the conductive sheet contacts the socket, improve the current transmission efficiency, and prevent the free end of the conductive sheet from being oxidized and corroded during long-term use, thus extending the service life of the conductive sheet and ensuring long-term stable contact of the connector plug.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This modular connector plug divides the opening of the connecting block into a U-shaped first limiting groove, a second limiting groove, and a third limiting groove through a separator block. These grooves cooperate with the arc-shaped piece and the positioning piece on the conductive piece to initially limit the conductive piece from different directions. Then, through the cooperation of the threaded sleeve, screw, and fixing block, a clamping force is applied to the arc-shaped piece to achieve secondary fixation of the conductive piece. At the same time, the anti-slip protrusion at the end of the positioning piece engages with the inner wall of the third limiting groove, further enhancing the positioning effect. The multiple cooperation of these components restricts the displacement and loosening of the conductive piece, solving the problem of easy displacement and loosening of the spring piece.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-5 This utility model provides a technical solution: a modular connector plug, including a connecting block 1 and a pair of conductive sheets 2. A pair of openings are formed on one side of the connecting block 1. The connecting block 1 has a cavity on the side opposite to the openings. A pair of partition blocks 8 are installed in the cavity. One side of each partition block 8 is located within the pair of openings, dividing the openings into three parts: a first limiting groove 5, a second limiting groove 6, and a third limiting groove 7. The first limiting groove 5, the second limiting groove 6, and the third limiting groove 7 form a U-shape. The partition block 8 has a slot 13, which communicates with the second limiting groove 6. An arc-shaped sheet 3 and a positioning sheet 4 are installed on the side of the conductive sheet 2. The conductive sheet 2 is located within the slot 13 and the second limiting groove 6, with its free end located outside the connecting block 1. The arc-shaped sheet 3 is located within the first limiting groove 5, and its bent portion abuts against the partition block 8. The positioning sheet 4 is located within the third limiting groove 7. The arc-shaped sheet on the side of the conductive sheet 2 is first... 3. Perform pre-bending treatment to maintain its elastic arc-shaped structure. Then, install the separator 8 in the cavity of the connecting block 1, and extend one side of the separator 8 into the opening of the connecting block 1, so that the separator 8 divides the opening into a U-shaped first limiting groove 5, a second limiting groove 6, and a third limiting groove 7. Then, align the main body of the conductive sheet 2 with the groove 13 of the separator 8, and apply slight pressure towards the main body of the conductive sheet 2 to the arc-shaped sheet 3, so that the arc-shaped sheet 3 produces a small elastic deformation to reduce the lateral dimension. Then, pass the main body of the conductive sheet 2 through the groove 13 and place it in the second limiting groove 6. At the same time, release the pressure on the arc-shaped sheet 3, so that it elastically resets and is correspondingly inserted into the first limiting groove 5, so that the bent part of the arc-shaped sheet 3 abuts against the arc surface of the separator 8. Finally, embed the positioning piece 4 on the conductive sheet 2 into the third limiting groove 7, so that the free end of the conductive sheet 2 extends to the outside of the connecting block 1, completing the initial installation and limiting of the conductive sheet 2.
[0021] Specifically, a detachable cover plate is provided at the cavity opening, and several positioning posts are provided on the edge of the cover plate. Positioning holes adapted to the positioning posts are opened at the corresponding positions of the cavity opening. After the positioning posts are inserted into the positioning holes, the cover plate fits against the surface of the connecting block 1. Several threaded holes are also provided on the cover plate, and corresponding built-in nuts are provided on the connecting block 1. The cover plate and the connecting block 1 are fixed by fastening screws passing through the threaded holes and engaging with the built-in nuts. A terminal is provided at the end of the conductive sheet 2 away from the free end. The terminal has a U-shaped clamp structure, and the inner wall of the terminal has conductive ridges. A clamping bolt is also provided on one side of the terminal. The clamping bolt passes through the side wall of the terminal and is threaded to the terminal. The end of the clamping bolt extends into the inside of the terminal and is fitted with a voltage-conducting block. A wire-passing hole corresponding to the terminal is opened on the side wall of the connecting block 1. After the external wire passes through the wire-passing hole, it extends into the U-shaped groove of the terminal. By tightening the clamping bolt, the voltage-conducting block is pushed, so that the voltage-conducting block and the wire are tightly abutted, realizing the electrical connection between the wire and the conductive sheet 2.
[0022] As an embodiment of this utility model, further, a pair of threaded sleeves 14 are respectively installed on the wall of the cavity near a pair of partition blocks 8. A pair of fixing blocks 9 are provided inside the cavity. The fixing blocks 9 have through holes 10, and the threaded sleeves 14 can slide in the through holes 10. A screw 11 also slides in the through holes 10. The screw 11 and the threaded sleeves 14 are engaged and connected. The screw head of the screw 11 abuts against the fixing block 9, and the fixing block 9 abuts against the bent end of the arc-shaped piece 3. First, the threaded sleeves 14 are installed on the wall of the cavity of the connecting block 1 near the partition blocks 8. Next, place the fixing block 9 into the cavity, so that the threaded sleeve 14 passes through the through hole 10 of the fixing block 9. Then, pass the screw 11 through the through hole 10 and engage it with the threaded sleeve 14. At this time, the screw head of the screw 11 will abut against the fixing block 9. Then, screw 11 is screwed, and the screw 11 rotates in the threaded sleeve 14 and drives the fixing block 9 to slide along the axial direction of the threaded sleeve 14 until the fixing block 9 abuts tightly against the bent end of the arc-shaped piece 3. The secondary fixing of the conductive piece 2 is achieved by using the clamping action of the fixing block 9 against the arc-shaped piece 3.
[0023] As an embodiment of this utility model, the surface of the fixing block 9 has a countersunk hole 15, which is coaxially connected with the through hole 10. The screw head of the screw 11 is located in the countersunk hole 15, and the screw head of the screw 11 has a regular hexagonal groove 12. When processing the fixing block 9, the countersunk hole 15 coaxial with the through hole 10 is first processed on its surface. When installing the screw 11, the screw 11 is passed through the through hole 10, so that the screw head of the screw 11 is embedded in the countersunk hole 15. When it is necessary to tighten the screw 11, the hexagonal wrench is inserted into the regular hexagonal groove 12 of the screw head of the screw 11, and then the hexagonal wrench is rotated to drive the screw 11 to rotate in the threaded sleeve 14, thereby realizing the tightening or loosening operation of the screw 11.
[0024] As an embodiment of this utility model, the separator 8 and the fixing block 9 are both made of insulating material. When manufacturing the separator 8 and the fixing block 9, insulating materials such as plastic and ceramic are selected for processing. When the separator 8 contacts the conductive sheet 2 and the arc-shaped sheet 3, and when the fixing block 9 abuts against the arc-shaped sheet 3, the insulating material separator 8 and the fixing block 9 will block the current from being conducted through themselves to the connecting block 1 or the outside, thereby forming an insulating isolation between the conductive parts and the non-conductive parts.
[0025] As an embodiment of this utility model, the end face of the separator 8 located in the cavity is an arc surface, and the arc degree is the same as the inner arc degree of the arc piece 3. When processing the separator 8, its end face located in the cavity is processed into an arc surface with a specific arc degree, and the degree of the arc surface is consistent with the inner arc degree of the arc piece 3. When the arc piece 3 is placed in the first limiting groove 5 and abuts against the separator 8, the inner arc surface of the arc piece 3 will completely fit with the arc surface of the separator 8, so that the contact between the two is a surface contact rather than a point contact, thereby achieving stable positioning and force dispersion of the arc piece 3.
[0026] As an embodiment of this utility model, the positioning piece 4 is further defined as a rectangular sheet structure. The end of the positioning piece 4 away from the conductive sheet 2 is provided with anti-slip protrusions. The anti-slip protrusions fit into the inner wall of the third limiting groove 7. The positioning piece 4 is first processed into a rectangular sheet shape, and anti-slip protrusions are processed at the end away from the conductive sheet 2. When the positioning piece 4 is embedded in the third limiting groove 7, the rectangular sheet body of the positioning piece 4 contacts the inner wall of the third limiting groove 7. At the same time, the anti-slip protrusions at the end of the positioning piece 4 will engage with the inner wall of the third limiting groove 7. The clamping force and friction between the anti-slip protrusions and the groove wall restrict the movement of the positioning piece 4 in the third limiting groove 7, thereby fixing the position of the conductive sheet 2.
[0027] As an embodiment of this utility model, the surface of the free end of the conductive sheet 2 is further gold-plated. A gold film is plated on the surface of the free end of the conductive sheet 2 using electroplating and other processes. When the free end of the conductive sheet 2 comes into contact with the contact component of the matching socket, the gold film acts as a conductive medium. Due to its good conductivity, the current can be transmitted smoothly. At the same time, the chemical properties of gold are stable, which can isolate the corrosion of the substrate of the conductive sheet 2 by air and moisture, and prevent oxidation, rust, etc. from occurring at the free end of the conductive sheet 2.
[0028] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
