Description

Technical Field

[0001] This application belongs to the field of connector technology, and specifically relates to a connector terminal and a connector. Background Technology

[0002] Connectors are common components used to achieve electrical connections, serving the purpose of power transmission or signal transmission. Depending on the application and scenario, connector types vary. Wiring connectors are a common type, used to establish electrical connections between circuit boards and other external modules. This allows for upgrades, maintenance, and power supply to devices containing the circuit board via these external modules.

[0003] In related technologies, when wired connectors are connected to circuit boards, it is usually necessary to use both male and female connectors. One of them is pre-fixed on the circuit board and is plugged into the other connector with wires when an electrical connection is needed. This makes the connection operation more convenient. However, the connector pre-fixed on the circuit board occupies a certain amount of space and cannot meet the needs of miniaturization of the equipment.

[0004] The pins on the male connector can be directly plugged into the connection sockets on the circuit board. However, the connection between the pins and the connection sockets is not stable and is prone to loose connections, which can affect the transmission of current or signals. It may even detach directly from the circuit board, affecting normal operation. Summary of the Invention

[0005] This application provides a connector terminal and a connector. After the terminal is installed inside the connector, the plug part can be directly plugged into the connection hole on the circuit board and maintain a reliable elastic connection with the connection hole. It has good electrical connectivity and connection stability, and the connection operation is simple. It can also save space on the circuit board and reduce costs.

[0006] In a first aspect, this application provides a connector terminal block, comprising:

[0007] The insertion part includes a guide part and an elastic abutment part that are connected to each other. The elastic abutment part includes a plurality of ribs that are parallel to and spaced apart along the insertion direction of the insertion part. The middle part of the ribs protrudes outward from opposite ends, so that the elastic abutment part forms a cage-like structure.

[0008] The mounting portion includes a cylindrical positioning portion connected to the elastic abutment portion, for mounting within the insulating body of the connector and being positioned therein;

[0009] The wiring section, connected to the mounting section, is used for electrical connection with the wire.

[0010] According to the terminal block provided in this application, the terminal block is a male terminal. After being installed inside the insulating body of the connector, the insertion part of one end of the terminal block can be directly inserted into the connection socket of the circuit board or the female terminal. The terminal block also elastically abuts against the inner wall of the connection socket or the female terminal through its outwardly convex, cage-like elastic abutment. This results in good electrical connectivity of the terminal block provided in this application, preventing loose connections. The insertion stability is also good; the insertion part will not detach from the connection socket or the female terminal, ensuring reliable connection. The other end of the terminal block is connected to a wire, which can then be used to connect to other electronic modules or power supplies.

[0011] Because the connector portion of the terminal block provided in this application includes a protruding and elastic abutment portion, it can be directly inserted into the connection socket on the circuit board to achieve electrical connection. This eliminates the need to pre-fix another matching connector on the circuit board for insertion, saving space on the circuit board to meet the miniaturization requirements of electronic devices and reducing costs. Furthermore, it facilitates user operation. When upgrading, testing, or powering circuit boards already encapsulated in equipment, it is often necessary to connect the circuit board to external modules. The insertion method is simple, convenient, and reliable, especially convenient for users performing connections during outdoor operations. The terminal block provided in this application can also be directly inserted into existing female terminals to achieve electrical conduction.

[0012] In conjunction with the first aspect, in one possible implementation, the front end face of the guide portion is formed by multiple lobes enclosing and forming a conical or arcuate surface, with gaps between adjacent lobes.

[0013] In conjunction with the first aspect, in one possible implementation, the mounting part further includes a triangular support part, which includes two side plates and a support base plate. One end of the two side plates is connected through the cylindrical positioning part and forms an included angle. The other end of the two side plates extends radially out of the cylindrical positioning part and is connected through the support base plate. The wiring part is connected to the support base plate.

[0014] In conjunction with the first aspect, in one possible implementation, the wiring portion includes:

[0015] A wiring base plate is connected to the supporting base plate;

[0016] The wiring clamp and the fixing clamp are used to electrically connect the core of the conductor and to press and fix the insulating shell of the conductor.

[0017] In conjunction with the first aspect, in one possible implementation, the support base plate is provided with barbs protruding outward, and the ends of the barbs are inclined toward the wiring portion.

[0018] Optionally, the terminal block is formed into an integral structure by a stamping process.

[0019] Specifically, the terminal block is made of a metallic material with good elasticity and excellent conductivity. Preferably, the terminal block is made of a copper alloy, which not only meets the requirements for elasticity and conductivity but also has low cost.

[0020] In a second aspect, this application provides a connector, including an insulating body and a terminal block provided by any possible implementation of the first aspect; the insulating body includes a base for mounting the terminal block and a cover that snaps onto the base;

[0021] The base is provided with a terminal slot, and the cover is provided with a corresponding positioning slot. The terminal slot and the positioning slot are connected to form a hole-like structure. The cylindrical positioning part is fixed in the hole-like structure, and the plug-in part extends out of the hole-like structure.

[0022] According to the connector provided in this application, the insulating body of the connector is formed by a base and a gland that interlock. When installing the terminal block into the base, the base forms a groove-like structure to accommodate the terminal block, i.e., the top is open rather than a closed hole-like structure. This allows the terminal block, especially the protruding elastic abutment portion, to pass through smoothly, and the elasticity of the elastic abutment portion is not damaged during assembly. By fastening the gland onto the base, a hole-like structure can be formed on the outer periphery of the cylindrical positioning portion, and the size of the hole-like structure matches the size of the cylindrical positioning portion, thereby positioning the cylindrical positioning portion, i.e., positioning the entire terminal block, within the insulating body. The insulating body of the connector provided in this application uses a clever two-piece interlocking structure, which not only achieves the positioning of the terminal block but also solves the problem of the protruding part of the elastic abutment portion being unable to be assembled through a hole. Furthermore, the assembly process is simple and convenient, and the assembled structure is reliable.

[0023] In conjunction with the second aspect, in one possible implementation, both the terminal slot and the positioning slot are arc-shaped slots, and the cylindrical positioning part is cylindrical.

[0024] In conjunction with the second aspect, in one possible implementation, the rear end of the base is provided with a connection to the terminal slot, allowing the wiring terminal to pass through a through hole into the terminal slot.

[0025] In conjunction with the second aspect, the connector includes two bases, and the positioning grooves are provided on both sides of the cover. The two bases are respectively fastened to the two sides of the cover. Attached Figure Description

Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] First, this application provides a connector terminal block, which is a male terminal block for installation inside the insulating body of the connector. It can be directly inserted into the connection socket on the circuit board and maintains a reliable elastic connection with the inner wall of the connection socket. It has good electrical connectivity and connection stability, and the connection operation is simple. It can also save space on the circuit board and reduce costs. The terminal block can also be directly inserted into other female terminals to establish an electrical connection.

[0042] This application provides a connector terminal 100, which is used in the connector. Figure 1 This is an overall schematic diagram of the wiring terminals of a connector provided in one embodiment of this application. Figure 2 This is a side view of a wiring terminal provided in an embodiment of this application. Figure 3 This is an overall schematic diagram of a connector provided in one embodiment of this application, as shown below. Figures 1-3 As shown, the terminal block 100 includes a plug-in portion 110, a mounting portion 120, and a wiring portion 130 connected in sequence.

[0043] The insertion portion 110 includes a guide portion 111 and an elastic abutment portion 112 connected to each other. The elastic abutment portion 112 includes a plurality of ribs 112a arranged parallel to and spaced apart along the insertion direction of the insertion portion 110. The middle part of each rib 112a protrudes outward relative to both ends, so that the elastic abutment portion 112 forms a cage-like structure. The mounting portion 120 includes a cylindrical positioning portion 121 connected to the elastic abutment portion 112. The mounting portion 120 is used to be installed in the insulating body 200 of the connector and positioned, so that the wiring terminal 100 is installed in the insulating body 200 and positioned. The wiring portion 130 is connected to the mounting portion 120 and is used to connect the wire 300.

[0044] like Figure 1 and Figure 2 As shown, the guide part 111, the elastic abutment part 112, and the cylindrical positioning part 121 are an integral cylindrical structure arranged coaxially.

[0045] Here, each rib 112a of the elastic abutment portion 112 is arranged parallel to the insertion direction of the insertion portion 110, that is, the rib 112a extends along the insertion direction of the insertion portion 110, and one end of the rib 112a in the length direction is connected to the end of the guide portion 111, and the other end is connected to the head end of the cylindrical positioning portion 121. The multiple ribs 112a are spaced apart, that is, multiple ribs 112a are arranged around the insertion direction of the insertion portion 110 as the central axis, and there is a gap between adjacent ribs 112a, so that the elastic abutment portion 112 forms a cage-like structure.

[0046] Furthermore, each rib 112 is arc-shaped in the length extension direction, with its middle part protruding outward relative to both ends. That is, in the radial direction of the cage-like elastic abutment part 112, the middle part of the elastic abutment part 112 protrudes outward and protrudes from the guide part 111.

[0047] With the above configuration, the elastic abutment part 112 has an overall convex lantern structure, and the rib 112a is the skeleton that supports the lantern.

[0048] In use, the insertion part 110 is inserted into the connection socket. The guide part 111 is located at the foremost end in the insertion direction and is used to guide the insertion so that the elastic abutment part 112 connected to the guide part 111 can smoothly enter the connection socket. The elastic abutment part 112 forms an outwardly convex cage-like structure with a hollow interior. The diameter of the convex portion in the middle is larger than the diameter of the connection socket. When the rib 112a is compressed radially from the inner wall of the connection socket, it can elastically deform inward, causing the elastic abutment part 112 to elongate axially as a whole. After deformation, the rib 112a has a tendency to return to its original shape, that is, a tendency to convex outward, thus maintaining a reliable connection with the inner wall of the connection socket.

[0049] According to the terminal block 100 provided in this embodiment, the terminal block 100 is a male terminal. After being installed inside the insulating body of the connector, the insertion portion 110 of one end of the terminal block 100 can be directly inserted into the connection socket or female terminal of the circuit board. It also elastically abuts against the inner wall of the connection socket or the inner wall of the female terminal through the outwardly convex cage-like elastic abutment portion 112. This results in good electrical connectivity of the terminal block 100 provided in this embodiment, preventing loose connections. The insertion stability is also good; the insertion portion 110 will not detach from the connection socket or female terminal, ensuring reliable connection. The other end of the terminal block 100 is connected to a wire 300, which allows it to be connected to other electronic modules or power supplies.

[0050] Since the plug-in portion 110 of the terminal block 100 provided in this application includes an outwardly protruding and elastically elastic abutment portion 112, it can be directly inserted into the connection socket on the circuit board to achieve electrical connection. There is no need to pre-fix another matching connector on the circuit board for insertion. This saves space on the circuit board, meeting the miniaturization requirements of electronic devices and reducing costs. Furthermore, it facilitates user operation. When upgrading, testing, or powering circuit boards already encapsulated in equipment, it is usually necessary to connect the circuit board to an external module. The plug-in method is simple, convenient, and reliable, especially convenient for users performing outdoor operations. The terminal block 100 provided in this application can also be directly plugged into existing female terminals to achieve electrical conduction.

[0051] Figure 4 yes Figure 3 The diagrams shown illustrate the connector assembly process: (a) the process of connecting the wires to the terminals; (b) the state after connecting the wires to the terminals; (c) the assembly of the terminals and the base; and (d) the assembly of the base and the gland. Figure 5 This is a schematic diagram of an insulating body provided in an embodiment of this application, as shown below. Figures 3-5 As shown, the connector provided in this application embodiment includes an insulating body 200 and a terminal block 100 provided in the aforementioned embodiment. The insulating body 200 includes a base 210 for mounting the terminal block 100 and a cover 220 that snaps onto the base 210.

[0052] Specifically, such as Figure 4 As shown in Figures (c) and (d), the base 210 is provided with a terminal groove 212, and the pressure cover 220 is provided with a corresponding positioning groove 222. The terminal groove 212 and the positioning groove 222 are connected to form a hole structure 201. The cylindrical positioning part 121 is fixed in the hole structure 201, and the insertion part 110 extends out of the hole structure 201.

[0053] Specifically, both the base 210 and the cover 220 are made of plastic material, which serves to insulate, support and fix the terminal 100, and can be integrally molded by injection molding process, which is simple, convenient and low cost to manufacture.

[0054] The connector provided in this application embodiment can accommodate multiple terminals 100, such as 4 or 8, etc. The number and arrangement of the terminals 100 depend on the specifications of the electronic module to be connected to the connector. For example, Figure 4 As shown in Figure (c), four terminal slots 212 are arranged side by side on the base 210, and each slot is separated by a slot wall so that the multiple wiring terminals 100 arranged side by side are also separated. At this time, the connector specification is 1x4pin.

[0055] Specifically, such as Figure 4 As shown in Figure (d), the base 210 and the pressure cover 220 are fastened together by the engagement of hooks 221 and slots 211. There are two slots 211, located on the left and right sides of the base 210 respectively, with corresponding hooks 221. The hooks 221 and slots 211 can also be interchanged.

[0056] This application does not limit the specific structure for the snap-fit ​​connection between the base 210 and the cover 220. Structures such as hook-hook and hook-slot are acceptable, as long as they can be snapped together and fixed together.

[0057] like Figure 4As shown in Figures (a) to (d), the assembly steps of the connector provided in this application embodiment are as follows:

[0058] Step 1: As shown in Figure (a), first connect the terminal 100 to the wire 300. The front end of the wire 300 exposes the conductive core 310, and the rest is wrapped by the insulating shell 320. Insert the wire 300 into the terminal 100 in the direction shown in Figure (a) to establish an electrical connection with the terminal 130 and fix it. The state diagram of the terminal 100 after the wire 300 is connected is shown in Figure (b).

[0059] Step 2: Insert the terminal 100 shown in (b) into the base 210 in the direction indicated by the arrow in (c), and make the plug-in part 110 extend out of the front end of the terminal slot 212, and place the cylindrical positioning part 121 in the terminal slot 212; repeat step 2 multiple times when the base 210 accommodates multiple terminals 100.

[0060] Step 3: Attach the pressure cap 220 to the base 210 along the direction indicated by the arrow in diagram (d). The pressure cap 220 and the base 210 together form the insulating body 200, thus creating... Figure 3 The structure of the connector is shown.

[0061] According to the connector provided in the embodiments of this application, the insulating body 200 of the connector is formed by a base 210 and a cover 220 that are interlocked. When the terminal 100 is installed in the base 210, since the base 210 is formed as a groove to accommodate the terminal 100, that is, the top is open rather than a closed hole, the terminal 100, especially the protruding elastic abutment portion 112, can pass smoothly, and the elasticity of the elastic abutment portion 112 will not be destroyed during the assembly process. By fastening the cover 220 on the base 210, a hole structure 201 can be formed on the outer periphery of the cylindrical positioning portion 121, and the size of the hole structure 201 matches the size of the cylindrical positioning portion 121, thereby positioning the cylindrical positioning portion 121, that is, positioning the entire terminal 100 within the insulating body 200. The connector provided in this application has a clever two-piece snap-fit ​​structure, which not only achieves the positioning of the terminal block 100, but also solves the problem that the protruding part of the elastic abutment part 112 cannot be assembled through a hole. Moreover, the assembly process is simple and convenient, and the assembled structure is reliable.

[0062] Preferably, the extension length of the perforated structure 201 is the same as the extension length of the cylindrical positioning part 121, so as to achieve a better positioning effect.

[0063] The connector provided in this application embodiment has one end connected to the connection socket on the circuit board via the plug part 110, and the other end is a wire 300 for connecting to another electronic module or power supply, thereby completing the relevant functions of the connector.

[0064] Optionally, both the terminal groove 212 and the positioning groove 222 are arc-shaped grooves, and the cylindrical positioning part 121 is cylindrical. Specifically, both the terminal groove 212 and the positioning groove 222 are semi-circular arc grooves, which are joined together to form a cylindrical hole.

[0065] Optionally, the arc size of the terminal groove 212 and the positioning groove 222 can be different, for example, one is a superior arc and the other is a inferior arc, so that they can be connected to form a cylindrical hole.

[0066] In other embodiments, the terminal groove 212 and the positioning groove 222 may also be square or the like. In this case, the cylindrical positioning part 121 is also square cylindrical. As long as a hole structure 201 matching the size of the cylindrical positioning part 121 is formed after docking, this application does not limit this.

[0067] like Figure 4 As shown in Figure (c), the end of the base 210 is provided with a through hole 213 communicating with the terminal slot 212, so that the wiring terminal 100 can pass through and enter the terminal slot 212. Specifically, the through hole 213 is square and large in size, so that the protruding elastic abutment part 112 can also pass through it smoothly.

[0068] With the above configuration, the end of the base 210 forms a closed perforation 213, which can enhance the strength of the base 210, that is, the entire insulating body 200. When the cover 220 is fastened onto the base 210, the surface of the cover 220 is flush with the upper outer wall of the perforation 213.

[0069] like Figure 4 As shown in Figures (c) and (d), the base 210 is also provided with a triangular support part 122 for accommodating the terminal 100 and a receiving groove 202 for accommodating the wiring part 130. The bottom wall of the receiving groove 202 is lower than the bottom wall of the terminal groove 212. The cover 220 is also provided with a corresponding receiving groove 202. The receiving groove 202 is square. When the two receiving grooves 202 are joined together, a square hole is formed. The size of the square hole is relatively large, so it can accommodate wires 300 with different diameters.

[0070] The receiving groove 202 on the base 210 is located between the terminal groove 212 and the through hole 213, connecting the two; one end of the receiving groove 202 on the cover 220 is connected to the positioning groove 222, and the other end is an open structure.

[0071] It should be understood that the groove-like or hole-like structures formed on the base 210 and the cover 220 are through in the installation and insertion direction of the terminal block 100.

[0072] like Figure 4 As shown in Figure (c), the upper and lower outer walls of the perforation 213 are also provided with outwardly protruding hand grips 215. The hand grips 215 are used for users to hold and perform plugging and unplugging operations. The upper and lower hand grips 215 are of different lengths, which makes it easier for users to distinguish the front and back of the connector and makes the connection operation more convenient.

[0073] Figure 6 This is a schematic diagram of a cap provided in another embodiment of this application. Figure 7 This is an overall schematic diagram of a connector provided in another embodiment of this application, as shown below. Figure 6 and Figure 7 As shown, in this embodiment, the connector includes two bases 210, and the two sides of the pressure cover 220 are provided with positioning grooves 222. The two bases 210 are respectively fastened to the two sides of the pressure cover 220.

[0074] With the above configuration, positioning grooves 222 are formed on both the upper and lower sides of the pressure cover 220. This connector can accommodate multiple terminals 100 side by side in the horizontal direction, and can also accommodate two rows of terminals 100 side by side in the vertical direction, thus meeting the connection requirements of different specifications. For example, Figure 7 The connector shown is a 2x4 pin specification.

[0075] Specifically, when the connector includes two bases 210, the front and back of the connector can be distinguished by providing a handle 215 on one base 210 and not providing one on the other.

[0076] like Figure 1 and Figure 2 As shown, the front end face of the guide portion 111 is formed by multiple lobes 111a enclosing and forming a conical or arcuate surface, with gaps between adjacent lobes 111a.

[0077] Here, there are at least two, or three or four, etc. The multiple lobes 111a surround the guide portion 111, making it a hollow cylindrical structure. For example, it forms a cone or hemisphere, thus having an inclined or curved guide surface. From the front end to the rear end of the guide portion 111, its radius gradually increases. It can play a guiding role in the process of inserting the plug portion 110 into the connection socket, so that the elastic abutment portion 112 can smoothly enter the connection socket. The gap between the lobes 111a and the lobes 111a also gives the guide portion 111 the ability to elastically deform.

[0078] like Figure 1As shown, the mounting portion 120 of the terminal block 100 also includes a triangular support portion 122. The triangular support portion 122 includes two side plates 122a and a support base plate 122b. One end of the two side plates 122a is connected by a cylindrical positioning portion 121 and forms an included angle. The other end of the two side plates 122a extends radially out of the cylindrical positioning portion 121 and is connected by the support base plate 122b. The wiring portion 130 is connected to the support base plate 122b.

[0079] Preferably, the cross-section of the triangular support 122 is an equilateral triangle or an isosceles triangle, and the legs of the isosceles triangle are the two side plates 122a.

[0080] When the terminal block 100 is installed in the base 210, the triangular support 122 and the wiring portion 130 are located in the receiving groove 202, and the front end face of the triangular support 122 (the end not connected to the wiring portion 130) abuts against the rear end of the terminal groove 212. Therefore, the terminal block 100 will not move forward when the connector is pulled out. The triangular support 122 has a triangular cross-section, high structural strength, and good support performance and connection reliability.

[0081] like Figure 1 and Figure 2 As shown, the support base plate 122b has outward protrusions of barbs 122c, and the ends of the barbs 122c are inclined toward the wiring portion 130.

[0082] like Figure 3 As shown, the wiring portion 130 is used to cooperate with the limiting portion 214 on the base 210 to limit the terminal. Specifically, the limiting portion 214 is the bottom wall of the receiving groove 202, and a gap is formed between the end of the limiting portion 214 and the front end of the base 210. This gap is used to accommodate the barb 122c. When the wiring terminal 100 is installed in the base 210, the end of the barb 122c abuts against the end of the limiting portion 214, so that the wiring terminal 100 will not move backward and be pushed out of the connector during the process of inserting the connector into the connection socket. This limiting structure is simple and reliable.

[0083] like Figure 1 and Figure 2 As shown, the wiring section 130 includes a wiring base plate 131 connected to the support base plate 122b, a wiring clamping plate 132, and a fixing clamping plate 133. The wiring clamping plate 132 is used to electrically connect the wire core 310 of the conductor 300, and the fixing clamping plate 133 is used to press and fix the insulating shell 320 of the conductor 300. Specifically, the wiring base plate 131 is connected to the support base plate 122b and extends rearward. In the direction of rearward extension, the wiring clamping plate 132 and the fixing clamping plate 133 are provided in sequence. There are two wiring clamping plates 132, which are respectively connected to the left and right sides of the wiring base plate 131. There are also two fixing clamping plates 133, which are respectively connected to the left and right sides of the wiring base plate 131.

[0084] like Figure 1 As shown and Figure 4 As shown in Figure (a), when the terminal block 100 is not connected to the wire 300, the terminal block base plate 131 and the terminal clamping plates 132 on both sides are U-shaped, and the opening of the U-shape is outward. The fixing clamping plate 133 and the terminal block base plate 131 are also U-shaped with outward opening; Figure 4 As shown in Figure (b), when the terminal block 100 connects and fixes the wire 300, the two terminal clamps 132 are bent inward and pressed against the wire core 310 to realize the electrical connection between the terminal block 100 and the wire 300, and the two fixing clamps 133 are bent inward and pressed against the insulating shell 320 to fix the wire 300.

[0085] In the embodiments of this application, the terminal block 100 is made into an integral structure by a stamping process, specifically, it is integrally stamped from a metal sheet.

[0086] The terminal block 100 provided in this application embodiment is made of a metallic material with good elasticity and excellent conductivity. Preferably, it is made of a copper alloy material, such as phosphor bronze or beryllium copper. These materials can meet the requirements of elasticity and conductivity, and also have good performance in terms of wear resistance and fatigue resistance. They are highly reliable and have low cost. The terminal block 100 made of these materials has good connection reliability and stability.

[0087] In the embodiments of this application, the terminal block 100 is integrally stamped from a sheet of beryllium copper alloy or phosphor bronze alloy. Specifically, pressure is applied to the copper alloy sheet using a mold and stamping equipment to cause plastic deformation or separation of the copper alloy sheet, thereby forming... Figure 1 The structure of the terminal block 100 is shown. It is manufactured using a die-stamping process, which is highly efficient, consumes less material, is suitable for mass production, and is easy to operate. The stamped, one-piece terminal block exhibits good dimensional accuracy and strength, resulting in a high yield rate and low processing costs, thus enhancing the product's competitiveness in the market.
