Description

Technical Field

[0001] This utility model relates to the field of conductive terminal technology, and in particular to a terminal block and a connector having the terminal block. Background Technology

[0002] Existing crimp terminals are generally made of conductive sheets through a stamping process. These crimp terminals typically include a plug portion and a wire clamping portion located at opposite ends, and a positioning portion connecting the plug portion and the wire clamping portion, forming a receiving portion between them. Both the plug portion and the positioning portion are cylindrical, and the inner cavities of the positioning portion and the plug portion communicate with the receiving portion. When these crimp terminals are used in overmolded connectors, the overmolding material easily enters the inner cavities of the positioning portion and the plug portion, causing poor contact, increased contact resistance, or the overmolding material occupying the mating space of the plug, preventing proper mating. Therefore, the inner cavity of the positioning portion needs to be sealed before overmolding the crimp terminal. Currently, after connecting the wire clamping portion, a rubber plug is inserted into the receiving portion to seal the inner cavity of the positioning portion before overmolding. However, since the rubber plug needs to be assembled after connecting the wire clamping portion, the already limited space of the receiving portion becomes even more difficult to assemble, resulting in low assembly efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal block and a connector having the terminal block.

[0004] This utility model provides a terminal block, which includes a connector and an isolator. The connector includes a plug-in portion and a crimping portion located at opposite ends, and a connecting portion connecting the plug-in portion and the crimping portion. The connector has a through groove that passes through the plug-in portion, the connecting portion and the crimping portion. The isolator is fixedly connected to the connecting portion and blocks the through groove. The outer peripheral wall of the isolator protrudes from the outer peripheral surface of the connecting portion.

[0005] This utility model also provides a connector, which includes a connector core and terminals. The connector core has an interconnected assembly hole and a positioning hole. The inner diameter of the assembly hole is larger than the inner diameter of the positioning hole. The connector core forms an assembly platform between the assembly hole and the positioning hole. The terminals include a connector and a separator. The connector includes a plug portion and a crimp portion located at opposite ends, and a connecting portion connecting the plug portion and the crimp portion. The connector has a through groove that passes through the plug portion, the connecting portion, and the crimp portion. The separator is fixedly connected to the connecting portion and blocks the through groove. The outer peripheral wall of the separator protrudes from the outer peripheral surface of the connecting portion. The plug portion of the terminals is accommodated in the positioning hole. The separator is positioned in the assembly hole. The assembly platform supports the separator.

[0006] The connection portion of the terminal block in this application is provided with an isolator that blocks the through groove. When the terminal block is coated with adhesive, the through groove is blocked by the isolator, which prevents the adhesive material from flowing into the plug portion from the through groove, thus avoiding poor contact of the terminal block, increased contact resistance, or the adhesive material occupying the mating space of the plug and causing misalignment. Secondly, the isolator and the terminal block are an integral structure, so there is no need to insert the isolator into the through groove on the connection portion before coating the terminal block with adhesive, and the terminal block can be coated directly, resulting in high manufacturing efficiency.

[0023] Please see Figures 1-4 One embodiment of this utility model provides a connector 100, which includes a connector core 20 and a terminal block 40. The terminal block 40 is mounted on the connector core 20 and includes a connector 42 and a separator 45. The connector 42 includes a plug portion 421 and a crimp portion 423 located at opposite ends, and a connecting portion 425 connecting the plug portion 421 and the crimp portion 423. The connector 42 has a through groove 424 that passes through the plug portion 421, the connecting portion 425, and the crimp portion 423. The separator 45 is fixedly connected to the connecting portion 425 and blocks the through groove 424. The outer peripheral surface 450 of the separator 45 protrudes from the outer surface 4250 of the connecting portion 425. The plug portion 421 is used to mate with an external conductive terminal, and the crimp portion 423 is used to crimp a conductive cable. When the terminal block 40 is coated with adhesive, the end of the wire clamping part 423 and the connecting part 425 near the wire clamping part 423 is coated with adhesive. The adhesive wraps the wire clamping part 423 and the end of the isolation member 45 away from the plug-in part 421, and the adhesive fills the section of the through groove 424 away from the plug-in part 421.

[0024] The terminal block 40 of this application has an isolator 45 on its connecting portion 425. This isolator 45 blocks the through groove 424. When the terminal block 40 is coated with adhesive, the through groove 424 is blocked by the isolator 45, preventing the adhesive material from flowing from the through groove 424 into the plug portion 421. This avoids poor contact and increased contact resistance of the terminal block 40, or prevents the adhesive material from occupying the plug mating space and causing misalignment. Secondly, the isolator 45 is directly fixed to the connecting portion 425, that is, the isolator 45 and the terminal block 40 are an integral structure. Before coating the terminal block 40, it is not necessary to insert the isolator 45 into the through groove 424 on the connecting portion 425. The terminal block 40 can be coated directly, resulting in high manufacturing efficiency.

[0025] like Figures 3-8 As shown, the connecting portion 425 includes a connecting piece 4251 and a reinforcing piece 4253. The connecting piece 4251 is connected to the insertion portion 421 and the crimping portion 423. The reinforcing piece 4253 is connected to the connecting piece 4251 and is disposed within the isolation member 45. The reinforcing piece 4253 is used to enhance the strength of the isolation member 45. Specifically, the reinforcing piece 4253 is a strip-shaped piece, and its opposite ends are respectively connected to the opposite sides of the connecting piece 4251 in the through groove 424. The isolation member 45 is positioned between the connecting piece 4251 and the reinforcing piece 4253. In this embodiment, the connecting piece 4251 is an arc-shaped piece, with its opposite ends along its axial direction connected to the insertion part 421 and the pressure part 423, respectively. The reinforcing piece 4253 is also arc-shaped, with its opposite ends connected to the opposite sides of the connecting piece 4251. The reinforcing piece 4253 and the connecting piece 4251 form a circular hole 4254, which is sealed by the isolator 45. The through groove 424 connects to the circular hole 4254, and the circular hole 4254 and the through groove 424 are coaxial. The width of the reinforcing piece 4253 is 1.5 mm to 2.0 mm.

[0026] Optionally, the connecting piece 4251 and the reinforcing piece 4253 are coaxial, and the radius of the connecting piece 4251 is equal to the radius of the reinforcing piece 4253. The connecting piece 4251 has a clearance groove 4255 and a coating space 4257 on opposite sides of the reinforcing piece 4253. The clearance groove 4255 is located between the reinforcing piece 4253 and the insertion part 421, and the coating space 4257 is located between the reinforcing piece 4253 and the wire clamping part 423. Both the clearance groove 4255 and the coating space 4257 are connected to the through groove 424. The opposite sides of the isolator 45 are located in the clearance groove 4255 and the coating space 4257, respectively. When the terminal 40 is coated, the coating material fills the section of the through groove 424 away from the insertion part 421 and the coating space 4257, and the isolator 45 stops the coating material.

[0027] Optionally, the insertion part 421 includes a first sleeve 4212 and a second sleeve 4214 located at opposite ends thereon, and an elastic abutment sleeve 4215 connected between the first sleeve 4212 and the second sleeve 4214. The first sleeve 4212, the elastic abutment sleeve 4215 and the second sleeve 4214 are coaxial. One end of the first sleeve 4212 away from the second sleeve 4214 is connected to the end of the connecting piece 4251. The first sleeve 4212 and the connecting piece 4251 are coaxial. The elastic abutment sleeve 4215 includes a plurality of elastic strips 4216. The opposite ends of each elastic strip 4216 are respectively connected to the first sleeve 4212 and the second sleeve 4214. The plurality of elastic strips 4216 are arranged around the circumference of the first sleeve 4212. Specifically, the middle portion of the elastic strip 4216 bends inward into the through groove 424, and multiple elastic strips 4216 are arranged at uniform intervals around the circumference of the first sleeve 4212. The outer diameter of the elastic abutment cylinder 4215 is smaller than the outer diameter of the first sleeve 4212. In this embodiment, the outer diameter of the first sleeve 4212 is equal to the outer diameter of the second sleeve 4214, and the outer diameter of the middle portion of the elastic abutment cylinder 4215 is smaller than the outer diameter of the second sleeve 4214. Specifically, the length direction of the elastic strip 4216 is inclined to the axis of the elastic abutment cylinder 4215.

[0028] Optionally, the creasing portion 423 includes a connecting piece 4232, a wrapping piece 4234, and a creasing piece 4236. The connecting piece 4232 connects the connecting piece 4251 and the wrapping piece 4234, and the creasing piece 4236 connects the wrapping piece 4234. In this embodiment, both the connecting piece 4232 and the wrapping piece 4234 are arc-shaped, and the connecting piece 4232 and the wrapping piece 4234 are coaxial. The two creasing pieces 4236 are respectively connected to opposite sides of the wrapping piece 4234. Specifically, the radius of the wrapping piece 4234 is smaller than the radius of the connecting piece 4251, the radius of the end of the connecting piece 4232 connected to the wrapping piece 4234 is equal to the radius of the wrapping piece 4234, and the radius of the end of the connecting piece 4232 connected to the connecting piece 4251 is equal to the radius of the connecting piece 4251.

[0029] Optionally, the spacer 45 includes a force-bearing surface 451 and a positioning surface 453 located at opposite ends, and an outer peripheral surface 450 connecting the force-bearing surface 451 and the positioning surface 453. The force-bearing surface 451 faces the pressure line portion 423, and the positioning surface 453 faces the insertion portion 421. In this embodiment, the spacer 45 is disc-shaped, with both the force-bearing surface 451 and the positioning surface 453 being circular surfaces, and the outer peripheral surface 450 being annular. The outer diameter of the spacer 45 is larger than the outer diameter of the connecting portion 425, so that the spacer 45 encloses the connecting piece 4251 and the reinforcing piece 4253. The outer peripheral surface 450 is provided with barbs 455, which surround the circumference of the outer peripheral surface 450. Specifically, the barbs 455 are protruding strips that protrude from the outer peripheral surface 450, and a guide surface 4552 is provided on one side of the barbs 455, with the guide surface 4552 facing the positioning surface 453. The positioning surface 453 of the spacer 45 has a chamfer 456 between it and the outer peripheral surface 450. The chamfer 456 can be a right angle or a rounded corner.

[0030] When manufacturing the terminal block 40, the terminal block 42 is formed by stamping after cutting on the conductive sheet, followed by electroplating. A high-temperature resistant adhesive is then used to coat the reinforcing piece 4253 of the terminal block 42 to form an insulating piece 45. The connecting piece 4251 and the reinforcing piece 4253 are embedded inside the insulating piece 45, preventing axial displacement of the insulating piece 45 on the connecting part 425 and increasing the strength of the insulating piece 45. The insulating piece 45 and the connecting part 425 are coaxial, and the diameter of the insulating piece 45 is larger than the diameter of the connecting part 425. The outer peripheral surface 450 of the insulating piece 45 protrudes from the outer peripheral surface of the connecting part 425. This adhesive can withstand temperatures above 300 degrees Celsius and can be, but is not limited to, nylon, phenolic resin, or silicone adhesive. Understandably, in order to achieve the encapsulation process on the connecting portion 425 of the connector 42, the connector 42 must have an encapsulation and sealing structure around the reinforcing piece 4253. This encapsulation and sealing structure has a corresponding structural fit with the encapsulation mold, so that the reinforcing piece 4253 of the connector 42 is completely fixed and sealed in the encapsulation mold, ensuring the extrusion of glue during the encapsulation process. Because the encapsulation mold is an open mold with upper and lower openings, the size of the encapsulation space 4257 on the connector 42 is also required. If the radial dimension of the encapsulation space 4257 on the connecting portion 425 is much smaller than 50% of the diameter of the connecting portion 425, the mold cannot fill the encapsulation space 4257 completely, and the encapsulation material will be squeezed out from the gaps during encapsulation, resulting in poor encapsulation. If the radial dimension of the encapsulation space 4257 on the connecting portion 425 is much larger than 50% of the diameter of the connecting portion 425, it will reduce the radial cross-sectional area of ​​the isolator 45, affecting the current carrying capacity of the isolator 45. Therefore, the radial dimension of the overlay space 4257 in the connecting portion 425 is slightly larger than or equal to 50% of the diameter of the connecting portion 425 to ensure that the current carrying capacity of the separator 45 is as large as possible. In this embodiment, the radial dimension of the overlay space 4257 in the connecting portion 425 is equal to 50% of the diameter of the connecting portion 425.

[0031] The packaging of the terminal block 40 can be formed with conductive wire or as a single terminal block 40. Compared with the packaging with conductive wire, the encapsulation of a single terminal block 40 is easier to operate. Optionally, after the terminal block 40 is encapsulated, the conductive wire is pressed by the wire pressing part 423 to realize the assembly of the conductive wire and the terminal block 42. Then, the terminal block 40 is encapsulated as a finished product.

[0032] Since the isolator 45 is fixedly connected to the connector 42 by injection molding, it not only has high production efficiency but also improves the consistency of the connector 40. Secondly, the outer circumferential surface 450 of the isolator 45 has good roundness, and the radial positioning interference after assembly with the connector core 20 is consistent, so that the connector 40 maintains consistent force after assembly. In addition, the isolator 45 can completely block the through groove 424 of the connector 40, and can prevent the overmolding material from entering the plug part 421 from the through groove 424, thus reducing the risk of glue leakage.

[0033] Please refer to the following: Figures 1-2 and Figures 9-11 The connector core 20 has interconnected assembly holes 21 and positioning holes 23. The inner diameter of the assembly hole 21 is larger than the inner diameter of the positioning hole 23. The connector core 20 forms an assembly platform 24 between the assembly hole 21 and the positioning hole 23. The insertion portion 421 of the terminal 40 is accommodated in the positioning hole 23. The isolator 45 is positioned in the assembly hole 21, and the assembly platform 24 supports the isolator 45. In this embodiment, the connector core 20 has two mutually spaced assembly holes 21 and two mutually spaced positioning holes 23. The two assembly holes 21 are respectively connected to the two positioning holes 23. The connector core 20 forms an assembly platform 24 between each positioning hole 23 and the corresponding assembly hole 21. The insertion portions 421 of the two terminals 40 are respectively inserted into the two positioning holes 23. The isolators 45 of the two terminals 40 are respectively positioned in the two assembly holes 21, and the two assembly platforms 24 support the two isolators 45. The outer diameter of the spacer 45 is slightly larger than the inner diameter of the mounting hole 21 so that the spacer 45 can be stably positioned in the mounting hole 21.

[0034] Specifically, the connector core 20 is generally oblong in shape. Two mounting holes 21 are located on one end face of the oblong block, and two positioning holes 23 are located on the bottom face of the two mounting holes 21 respectively. The opposite end face of the oblong block is provided with two clearance holes 25 facing the two mounting holes 21. The inner diameter of the clearance holes 25 is larger than the inner diameter of the mounting holes 21, and the two clearance holes 25 extend along the axial direction of the mounting holes 21 to a position close to the mounting holes 21. The inner end face of each clearance hole 25 of the connector core 20 is provided with a plug-in sleeve 26 around the positioning hole 23, and the inner cavity of the plug-in sleeve 26 is the positioning hole 23.

[0035] Optionally, the inner circumferential surface of the assembly hole 21 is provided with a plurality of positioning blocks 212, which are arranged in a circle around the circumference of the assembly hole 21, and are used to abut against the outer circumferential wall of the spacer 45 respectively. Specifically, the positioning block 212 is a protrusion on the inner circumferential surface of the assembly hole 21, the length direction of which is parallel to the axial direction of the assembly hole 21; each positioning block 212 has an inclined guide surface 210 at one end opposite to the positioning hole 23. In this embodiment, six positioning blocks 212 are protruding on the inner circumferential surface of the assembly hole 21, and the six positioning blocks 212 are evenly spaced in a circle around the circumference of the assembly hole 21. In other embodiments, two, three, four, five, seven or eight positioning blocks 212 are protruding on the inner circumferential surface of the assembly hole 21.

[0036] like Figure 11 and Figure 12 As shown, when assembling the terminal blocks 40 to the connector core 20, the insertion portions 421 of the two terminal blocks 40 are respectively inserted into the two positioning holes 23 of the connector core 20. The spacers 45 slide along the guide surface 210 into the assembly holes 21. The two assembly tables 24 are respectively supported on the two spacers 45. Multiple positioning blocks 212 in each assembly hole 21 abut against the outer peripheral surface of the spacer 45. The barbs 455 are interference-fitted with the multiple outer positioning blocks 212, which is equivalent to the terminal block 42 having metal barbs, ensuring that the terminal blocks 40 are not easy to loosen after assembly, so that the spacers 45 are positioned in the two assembly holes 21, realizing the radial positioning of the terminal blocks 40 on the connector core 20. The terminal block 42 is formed by rolling the sheet metal. The spacers 45 are positioned in the assembly holes 21 of the connector core 20, which can prevent the interface from opening during the mating of the insertion portions 421 with the external terminals. The positioning surface 453 of the spacers 45 abuts against the assembly table 24 to realize the axial positioning of the terminal blocks 40. A first gap 262 exists between the outer peripheral surface of the elastic abutment cylinder 4215 and the inner peripheral surface of the plug-in cylinder 26. This first gap 262 can accommodate the elastic deformation of the elastic abutment cylinder 4215 during the insertion process with the external terminal. A second gap 264 exists between the end face of the second sleeve 4214 facing away from the elastic abutment cylinder 4215 and the inner end face of the plug-in cylinder 26. Since the terminal 40 has been axially positioned by the assembly table 24 and the positioning surface 453, the second gap 264 ensures that the terminal 40 is properly assembled. Because the isolator 45 has a force-bearing surface 451 and a positioning surface 453, it is convenient for the terminal 40 to apply force during assembly, thus completing the assembly efficiently. Because the isolator 45 cooperates with the six positioning blocks 212 inside the assembly hole 21, the force on the periphery of the isolator 45 is uniform, which can improve the consistency of the holding force of the terminal 40. The outer peripheral surface of the isolator 45 is provided with barbs 455 to ensure that the terminal 40 is not easily loosened after assembly; the isolator 45 has chamfers 456 to facilitate the assembly of the terminal 40 to the connector core 20.

[0037] The isolator 45 on the terminal block 40 of this utility model is directly fixedly connected to the terminal block 42. This not only solves the problem of low production efficiency of existing products and reduces the risk of glue leakage, but also optimizes the consistency of the terminal block 40, greatly improves the production efficiency of the terminal block 40, simplifies the processing technology of the terminal block 40, and significantly reduces the labor cost of the terminal block 40.

[0038] The connector of this utility model embodiment can be widely used in various fields such as automobiles, communications, computers, consumer electronics, industry, and transportation. For example, it can be used as a key component in new energy vehicles, electric bicycles, electric motorcycles, and electric scooters, specifically in the motors of various types of vehicles. Its applications are very wide and are not limited to the examples provided.

[0039] The embodiments of this utility model have been described in detail above. Specific examples have been used in this article to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model.
