Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to an electrical connector terminal block. Background Technology

[0002] Electrical connectors typically feature a piercing section, which is U-shaped and cuts the cable's insulation after it enters the piercing section. For example, patent application CN119764878A discloses an anti-loosening electrical connector for electromechanical equipment, comprising a coaxially inserted ferrule and a piercing tube. Multiple cables are held inside the ferrule, and the piercing tube has multiple piercing tabs, each corresponding to a cable. Each piercing tab has a locking groove, and the groove contains a cutting section for cutting the cable's insulation.

[0003] However, this cutting method can only scratch the insulation sheath, creating only a gap in it. This gap results in a small conductive contact area between the conductive sheet and the wire core, thus leading to poor conductivity stability of the electrical connector. Summary of the Invention

[0004] Therefore, it is necessary to provide an electrical connector terminal to address the current technical problem of poor conductivity stability in electrical connectors.

[0005] The above objectives are achieved through the following technical solutions: An electrical connector terminal block includes a male terminal block and a female terminal block. The male terminal block includes a first housing. Multiple cables are arranged circumferentially inside the first housing. The end of each cable extends radially along the first housing. The cable consists of an insulating sheath and a wire core. The female terminal block includes a second housing, which is coaxially connected to the first housing. The interior of the second housing has multiple stripping components arranged circumferentially, each corresponding to one end of the cable. Each stripping component includes a first cutting component and a second cutting component. The first and second cutting components have the same structure; the first cutting component includes a first cutting blade and a first conductive sheet, and the second cutting component includes a second cutting blade and a second conductive sheet. The lengths of both the first and second cutting blades extend axially along the second housing. In the initial state, the first cutting blade and the second cutting blade are positioned opposite each other; the end of the cable can enter between the first cutting blade and the second cutting blade; the second housing is provided with a driving component, which can make the first cutting blade and the second cutting blade rotate in a direction away from the axis of the second housing, thereby peeling the insulation sheath of the cable end from the wire core, and at the same time, the first conductive sheet and the second conductive sheet contact the wire core.

[0006] Furthermore, the first cutting assembly further includes a first driving rod, the length of which extends axially along the second housing, and a first connecting seat is connected to one end of the first driving rod near the first housing. The length of the first connecting seat extends radially along the first driving rod, and both the first cutting blade and the first conductive sheet are disposed on the first connecting seat. The second cutting assembly further includes a second driving rod, the length of which extends axially along the second housing, and a second connecting seat is connected to one end of the second driving rod near the first housing. The length of the second connecting seat extends radially along the second driving rod, and both the second cutting blade and the second conductive sheet are disposed on the second connecting seat.

[0007] Furthermore, both the first and second conductive sheets are arc-shaped conductive sheets, with the arc length extending along the axial direction of the second outer shell and the radius of the arc-shaped conductive sheet being consistent with the maximum radius of the wire core.

[0008] Furthermore, the drive assembly includes a drive ring coaxially rotatably disposed outside the second housing. An inner rotating ring and an outer rotating ring are coaxially disposed inside the second housing, with the inner rotating ring located inside the outer rotating ring. The drive ring, outer rotating ring, and inner rotating ring are fixedly connected by a connecting rod extending radially along the second housing. An outer gear ring is disposed on the outer circumferential surface of the inner rotating ring, and an inner gear ring is disposed on the inner circumferential surface of the outer rotating ring. A first gear is disposed at the end of the first drive rod away from the first housing, and a second gear is disposed at the end of the second drive rod away from the first housing. The first gear meshes with the outer gear ring, and the second gear meshes with the inner gear ring. The first drive rod and the second drive rod can rotate synchronously in opposite directions.

[0009] Furthermore, the connecting rod is provided in multiple ways, and the second outer shell is provided with multiple arc-shaped grooves in the circumferential direction. The arc-shaped grooves are coaxially arranged with the second outer shell, and the connecting rods correspond one-to-one with the arc-shaped grooves, and the connecting rods can slide along the arc-shaped grooves.

[0010] Furthermore, the first connecting seat is provided with a first elongated hole extending along its length direction, and the second connecting seat is provided with a second elongated hole extending along its length direction. The end of the first driving rod can slide along the first elongated hole, and the end of the second driving rod can slide along the second elongated hole. A first compression spring is provided between the end of the first driving rod and the inner wall of the first elongated hole, and a second compression spring is provided between the end of the second driving rod and the inner wall of the second elongated hole. The first compression spring has a tendency to bring the first connecting seat closer to the axis of the second housing, and the second compression spring has a tendency to bring the second connecting seat closer to the axis of the second housing.

[0011] Furthermore, the first outer shell is provided with a plurality of heat dissipation pipes in a circumferential direction. The heat dissipation pipes extend radially along the first outer shell, and each heat dissipation pipe corresponds to a cable. An expansion assembly is provided in the heat dissipation pipe. The expansion assembly includes a screwing post, which is threaded into the heat dissipation pipe. A conical cylinder is provided at one end of the screwing post near the axis of the first outer shell. A plurality of push pins are provided on the inner wall of the conical cylinder. The axis of the push pins is perpendicular to the generatrix of the conical cylinder.

[0012] Furthermore, the inner wall of the conical cylinder is provided with a groove extending along its generatrix, and the push pin can slide along the groove.

[0013] Furthermore, the push pin is a conical pin, which has a large end and a small end. The large end of the conical pin slides along the groove, and the small end of the conical pin is used to insert into the wire core.

[0014] Furthermore, the end of the screwing column away from the axis of the first housing is provided with a drive groove, into which a tool is inserted to drive the screwing column to rotate.

[0015] The beneficial effects of this invention are: The electrical connector terminal provided by this invention, firstly, in use, after the first housing and the second housing are plugged in, the end of the cable enters between the first cutting blade and the second cutting blade. The first cutting blade and the second cutting blade first cut the insulation sheath of the cable, and then the driving assembly makes the first cutting blade and the second cutting blade rotate in a direction away from the axis of the second housing, so that the insulation sheath of the cable end is peeled off from the wire core. At the same time, the first conductive plate and the second conductive plate contact the wire core. Since the insulation sheath has been peeled off from the wire core, the conductive contact area between the first conductive plate and the second conductive plate and the wire core is large, thereby improving the conductivity stability of the electrical connector.

[0016] Second, the multiple push pins of the expansion assembly can be inserted into the wire core, thereby increasing the diameter of the wire core. This makes the wire core fit more tightly with the first conductive sheet and the second conductive sheet, further improving the conductivity stability. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0022] like Figures 1 to 9 As shown, an embodiment of the present invention provides an electrical connector terminal block, including a male terminal block and a female terminal block. The male terminal block includes a first housing 101, and multiple cables 103 are arranged circumferentially inside the first housing 101. The end of each cable 103 extends radially along the first housing 101, and the cable 103 is composed of an insulating sheath and a wire core. The female terminal block includes a second housing 102, which is coaxially inserted with the first housing 101. Multiple stripping components 200 are arranged circumferentially inside the second housing 102. Each stripping component 200 corresponds to one end of the cable 103. Each stripping component 200 includes a first cutting component and a second cutting component. The first cutting component and the second cutting component have the same structure and are located on both sides of the cable 103 in the circumferential direction of the second housing 102. The first cutting assembly includes a first cutting blade 209 and a first conductive sheet 206, and the second cutting assembly includes a second cutting blade 210 and a second conductive sheet 208. The lengths of the first cutting blade 209 and the second cutting blade 210 both extend along the axial direction of the second housing 102. In the initial state, the first cutting blade 209 and the second cutting blade 210 are arranged opposite to each other, and the end of the cable 103 can enter between the first cutting blade 209 and the second cutting blade 210. The second housing 102 is provided with a driving assembly, which can rotate the first cutting blade 209 and the second cutting blade 210 in a direction away from the axis of the second housing 102, thereby stripping the insulation sheath of the end of the cable 103 from the wire core, while the first conductive sheet 206 and the second conductive sheet 208 come into contact with the wire core.

[0023] In use, after the first housing 101 and the second housing 102 are plugged in, the end of the cable 103 enters between the first cutting blade 209 and the second cutting blade 210. The first cutting blade 209 and the second cutting blade 210 first cut the insulation sheath of the cable 103, and then the drive assembly rotates the first cutting blade 209 and the second cutting blade 210 in a direction away from the axis of the second housing 102, so that the insulation sheath at the end of the cable 103 is peeled off from the wire core. That is, the rotation of the first cutting blade 209 and the second cutting blade 210 can tear off the cut and connected part of the insulation sheath from the wire core, increasing the exposed area of ​​the wire core in the circumferential direction. At the same time, the first conductive plate 206 and the second conductive plate 208 come into contact with the wire core. Since the insulation sheath has been peeled off from the wire core, the conductive contact area between the first conductive plate 206 and the second conductive plate 208 and the wire core is large, thereby improving the conductivity stability of the electrical connector.

[0024] Specifically, the first cutting assembly further includes a first drive rod 2051, the length of which extends axially along the second housing 102. A first connecting seat 212 is connected to one end of the first drive rod 2051 near the first housing 101. The length of the first connecting seat 212 extends radially along the first drive rod 2051. The first cutting blade 209 and the first conductive sheet 206 are both disposed on the first connecting seat 212. The second cutting assembly further includes a second drive rod 2071, the length of which extends axially along the second housing 102. A second connecting seat 213 is connected to one end of the second drive rod 2071 near the first housing 101. The length of the second connecting seat 213 extends radially along the second drive rod 2071. The second cutting blade 210 and the second conductive sheet 208 are both disposed on the second connecting seat 213. This allows the first cutting blade 209 and the first conductive sheet 206 to rotate synchronously, and the second cutting blade 210 and the second conductive sheet 208 to rotate synchronously.

[0025] like Figures 6 to 9 As shown, both the first conductive sheet 206 and the second conductive sheet 208 are arc-shaped conductive sheets. The arc length of the arc-shaped conductive sheet extends along the axial direction of the second outer shell 102, and the radius of the arc-shaped conductive sheet is consistent with the maximum radius of the wire core. This results in a large conductive contact area between the arc-shaped conductive sheet and the wire core when the arc-shaped conductive sheet rotates to the position of contact with the wire core. The second outer shell 102 contains multiple wires 104, and the arc-shaped contact sheet corresponds one-to-one with each wire 104 and is conductively connected, thus achieving a conductive connection between the male contact terminal and the female contact terminal.

[0026] The drive assembly includes a drive ring 201 coaxially rotatably disposed outside the second housing 102. An inner rotating ring 204 and an outer rotating ring 203 are coaxially disposed inside the second housing 102, with the inner rotating ring 204 located inside the outer rotating ring 203. The drive ring 201, outer rotating ring 203, and inner rotating ring 204 are fixedly connected by a connecting rod 202 extending radially along the second housing 102. An outer gear ring is provided on the outer circumferential surface of the inner rotating ring 204, and an inner gear ring is provided on the inner circumferential surface of the outer rotating ring 203. A first gear 205 is provided at the end of the first drive rod 2051 away from the first housing 101, and a second gear 207 is provided at the end of the second drive rod 2071 away from the first housing 101. The first gear 205 meshes with the outer gear ring, and the second gear 207 meshes with the inner gear ring. The first drive rod 2051 and the second drive rod 2071 can rotate synchronously in opposite directions.

[0027] To avoid interference, the internal gear ring on the outer rotating ring 203 and the external gear ring on the inner rotating ring 204 are offset axially from each other in the second housing 102. The transmission ratio between the external gear ring and the first gear 205 is the same as the transmission ratio between the internal gear ring and the second gear 207, so that the first gear 205 and the second gear 207 rotate at the same speed but in opposite directions, thereby ensuring that the first cutting blade 209 and the second cutting blade 210 can rotate synchronously in opposite directions.

[0028] Furthermore, the connecting rod 202 is provided in multiple ways, and the second outer shell 102 is provided with multiple arc-shaped grooves 1021 in the circumferential direction. The arc-shaped grooves 1021 are coaxially arranged with the second outer shell 102. The connecting rod 202 corresponds one-to-one with the arc-shaped grooves 1021, and the connecting rod 202 can slide along the arc-shaped grooves 1021. The arc-shaped grooves 1021 can limit the rotation angle of the connecting rod 202, thereby limiting the rotation angle of the inner rotating ring 204 and the outer rotating ring 203, and thus controlling the rotation angle of the first cutting blade 209 and the second cutting blade 210, ensuring that the insulation sheath on the cable 103 can be just stripped.

[0029] The first connecting seat 212 is provided with a first elongated hole extending along its length direction, and the second connecting seat 213 is provided with a second elongated hole extending along its length direction. The end of the first driving rod 2051 can slide along the first elongated hole, and the end of the second driving rod 2071 can slide along the second elongated hole. A first compression spring 211 is provided between the end of the first driving rod 2051 and the inner wall of the first elongated hole, and a second compression spring 214 is provided between the end of the second driving rod 2071 and the inner wall of the second elongated hole. The first compression spring 211 has a tendency to bring the first connecting seat 212 closer to the axis of the second housing 102, and the second compression spring 214 has a tendency to bring the second connecting seat 213 closer to the axis of the second housing 102.

[0030] When the first connecting seat 212 rotates with the first driving rod 2051 and the second connecting seat 213 rotates with the second driving rod 2071, the first conductive plate 206 and the second conductive plate 208 will squeeze the cable 103, causing the first compression spring 211 and the second compression spring 214 to contract. The first connecting seat 212 can slide relative to the first driving rod 2051, and the second connecting seat 213 can slide relative to the second driving rod 2071, thereby avoiding rotational interference. When the first conductive plate 206 and the second conductive plate 208 rotate to the position of the corresponding outer circumferential surface of the wire core, the first compression spring 211 and the second compression spring 214 can extend, thereby resetting the first connecting seat 212 and the second connecting seat 213, and the first conductive plate 206 and the second conductive plate 208 are in contact with the outer circumferential surface of the wire core.

[0031] The second housing 102 is provided with a plurality of limiting protrusions inside. The first drive rod 2051 and the second drive rod 2071 rotate within the limiting protrusions to prevent displacement of the first drive rod 2051 and the second drive rod 2071.

[0032] like Figure 3 and Figure 4 As shown, the first outer casing 101 has multiple heat dissipation pipes 105 arranged circumferentially. The heat dissipation pipes 105 extend radially along the first outer casing 101, and each heat dissipation pipe 105 corresponds to a cable 103. An expansion assembly 300 is provided within each heat dissipation pipe 105. The expansion assembly 300 includes a screwing post 301 threadedly connected to the heat dissipation pipe 105. One end of the screwing post 301 near the axis of the first outer casing 101 is connected to a conical cylinder 303 via a mounting ring 302. The inner wall of the conical cylinder 303 has multiple pushing pins, the axis of which is perpendicular to the generatrix of the conical cylinder 303. The expansion assembly 300 is made of metal. The heat dissipation pipes 105 and the expansion assembly 300 can dissipate heat from the cable 103, thereby preventing the cable 103 from overheating.

[0033] The core is composed of multiple copper wires. The multiple push pins of the expansion assembly 300 can be inserted between the copper wires of the core, thereby expanding the copper wires outward and increasing the diameter of the core. This makes the core fit more tightly with the first conductive sheet 206 and the second conductive sheet 208, further improving the conductivity stability.

[0034] like Figure 4 As shown, the inner wall of the conical cylinder 303 is provided with a groove 3031 extending along its generatrix, and the push pin can slide along the groove 3031. The push pin is a conical pin 304, which has a large end and a small end. The large end of the conical pin 304 slides along the groove 3031, and the small end of the conical pin 304 is used for insertion into the wire core. The design of the conical pin 304 facilitates insertion into the gaps between copper wires.

[0035] Furthermore, the end of the screw-on column 301 away from the axis of the first housing 101 is provided with a drive groove 305, into which a tool is inserted to drive the screw-on column 301 to rotate. The drive groove 305 is a slotted groove or a cross groove, and the screw-on column 301 is rotated by a screwdriver.

[0036] Based on the above embodiments, the usage principle and working process of the embodiments of the present invention are as follows: The first outer shell 101 is inserted into the second outer shell 102, allowing the end of the cable 103 in the first outer shell 101 to enter between the first cutting blade 209 and the second cutting blade 210 in the second outer shell 102. The first cutting blade 209 and the second cutting blade 210 first cut the insulation sheath of the cable 103, and then rotate the drive ring 201, causing the drive ring 201 to drive the inner rotating ring 204 and the outer rotating ring 203 to rotate synchronously. Thus, the outer rotating ring 203 drives the second gear 207 to rotate through the internal gear ring, which in turn drives the second connecting seat 213 to rotate through the second drive rod 2071. The rotation of the second connecting seat 213 drives the second cutting blade 210 and the second conductive plate 208 to rotate. The inner rotating ring 204 drives the second connecting seat 213 to rotate through the external gear ring 2071. The gear ring drives the first gear 205 to rotate, which in turn drives the first connecting seat 212 to rotate via the first drive rod 2051. The rotation of the first connecting seat 212 drives the first cutting blade 209 and the first conductive plate 206 to rotate. The first cutting blade 209 and the second cutting blade 210 both rotate in a direction away from the axis of the second housing 102, causing the insulation sheath at the end of the cable 103 to be peeled off from the wire core. The peeled part is squeezed and corresponds to the conical cylinder 303 of the expansion component 300. At the same time, the first conductive plate 206 and the second conductive plate 208 come into contact with the wire core. Since the insulation sheath has been peeled off from the wire core, the conductive contact area between the first conductive plate 206 and the second conductive plate 208 and the wire core is large, thereby improving the conductivity stability of the electrical connector.

[0037] Then, the screwdriver drives the screwdriver to rotate the screwdriver column 301. The rotation of the screwdriver column 301 causes the conical cylinder 303 to gradually approach the wire core. The conical cylinder 303 can accommodate the stripped insulation sheath. The small end of the conical needle 304 is gradually inserted into the wire core. The continued rotation of the screwdriver column 301 allows the large end of the conical needle 304 to slide along the groove 3031. Since the conical needle 304 is always perpendicular to the generatrix of the conical cylinder 303, the diameter of the circle containing the multiple conical needles 304 is reduced, allowing the conical needle 304 to enter a position closer to the center of the wire core. As a result, the diameter of the wire core is further increased, and the wire core fits more tightly with the first conductive sheet 206 and the second conductive sheet 208. After a period of use, the screwdriver can be used to rotate the screwdriver 301 to make the small end of the conical needle 304 insert deeper into the wire core. Since the conical needle 304 is conical, the size between the copper wires inserted into the wire core is increased, which can avoid loosening caused by plastic deformation of the wire core and improve the stability of the conductive connection.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
