Technical Field

[0001] This utility model relates to the field of terminal block technology, and specifically to a contact terminal block. Background Technology

[0002] "Touch-connect" terminal blocks can easily and efficiently connect conductive wires. However, in the current technology, the conductive wires are locked by a spring driven by a drive unit (often a button or test pen). When designing the terminal block housing, the wire inlet channel and the drive channel for the drive unit are often set on opposite sides. When the terminal block is placed in a small cabinet, wiring becomes inconvenient. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, in one aspect, a contact terminal block is provided, comprising:

[0037] The housing 1 is provided with an insertion channel 101 and a driving channel 102. The insertion channel 101 and the driving channel 102 are located on the same side of the housing 1. The insertion channel 101 is suitable for inserting a conductive wire 6.

[0038] A cage-type spring 2 is disposed inside the housing 1. The cage-type spring 2 includes an intermediate driving section 202 and a locking end 201. The intermediate driving section 202 is provided with a wire clamping hole 2025. The wire clamping hole 2025 is at least partially corresponding to the insertion channel 101. The cage-type spring 2 has a locking position and a wire clamping position.

[0039] The fluid carrier 5 is located inside the housing 1. The fluid carrier 5 is provided with a wire clamping plate 501, and part of the wire clamping plate 501 passes through the wire clamping hole 2025.

[0040] An actuation component is located inside the housing 1. The actuation component includes a connected trigger plate 3 and a locking tongue plate 4. The trigger plate 3 is provided with a trigger end 301.

[0041] Trigger end 301 is configured to be triggered by conductive wire 6, and linkage lock tongue plate 4 disengages from locking end 201; cage spring 2 switches from the locked position to the wire clamping position based on its own elasticity, and wire clamping plate 501 cooperates with the inner side wall of wire clamping hole 2025 in the wire clamping position to clamp conductive wire 6; intermediate drive section 202 is driven by the driving force in drive channel 102 and switches from the wire clamping position to the locked position. At this time, lock tongue plate 4 locks with locking end 201 to keep cage spring 2 in the locked position.

[0042] The drive channel 102 is adapted to accommodate a sliding drive component. By placing the insertion channel 101 and the drive channel 102 on the same side of the housing 1, and arranging the central axis of the insertion channel 101 and the central axis of the drive channel 102 parallel, the direction of button insertion, the direction of insertion of the conductive wire 6, and the direction of opening the cage-type spring 2 are the same, making it more convenient for users to perform wiring operations within the relatively small housing 1. Furthermore, the overall structure of the cage-type spring 2 is simpler and easier to manufacture and mass-produce. The connection is more reliable through the cooperation of the inner wall of the clamping plate 501 and the clamping hole 2025. In this embodiment, the cage-type spring 2 is made of an elastic conductive material (e.g., copper, silver, etc.), the button and housing 1 are made of insulating material (e.g., insulating plastic), the current carrier 5 is made of conductive material (e.g., copper, silver, etc.), the trigger plate 3 and the locking tongue plate 4 can be made of either conductive or insulating material, and the trigger plate 3 is made of elastic material. The drive component can be a commonly used component (e.g., a button) mounted on the housing 1, or a component not mounted on the housing 1 (e.g., a test pen). In addition, the cross-sectional area of ​​the wire clamping hole 2025 is greater than or equal to the cross-sectional area of ​​the insertion channel 101. This arrangement facilitates the smooth entry of the conductive wire 6 into the wire clamping hole 2025.

[0043] In one embodiment, such as Figure 1As shown, the cage-type spring 2 also includes a snap-fit ​​end 203. The intermediate drive section 202 includes a first intermediate drive segment 2021 and a second intermediate drive segment 2022. The first connection 2023 between the first intermediate drive segment 2021 and the second intermediate drive segment 2022 is arc-shaped. The second intermediate drive segment 2022 is connected to the snap-fit ​​end 203. The second connection 2024 between the second intermediate drive segment 2022 and the snap-fit ​​end 203 is arc-shaped. The snap-fit ​​end 203 abuts against the fluid carrier 5. The arc shape of the first connection 2023 allows it to abut against the button. The drive component causes the first connection 2023 to deform, thereby driving the locking end 201 to move. Since both the first connection 2023 and the second connection 2024 are arc-shaped, the volume occupied by the cage-type spring 2 within the housing 1 can be reduced, making the overall volume of the housing 1 smaller. The snap-fit ​​end 203 abuts against the fluid carrier 5, so that the fluid carrier 5 fixes the snap-fit ​​end 203 and restricts the snap-fit ​​end 203 from moving arbitrarily.

[0044] In one embodiment, such as Figure 1 As shown, the locking end 201 has a locking hole 2011. The locking tongue plate 4 extends into the locking hole 2011 in the locked position. The end of the locking end 201 facing away from the locking hole 2011 is bent, and the bending direction of the locking end 201 is inwardly recessed. The inwardly recessed bending setting gives the locking end 201 a guiding function. When the locking end 201 contacts the locking tongue plate 4, the bending setting avoids a rigid collision between the locking end 201 and the locking tongue plate 4, allowing the locking tongue plate 4 to extend into the locking hole 2011. It should be noted that the locking hole 2011 in this embodiment is a through hole.

[0045] In one embodiment, such as Figure 1 , Figure 5 and Figure 7 As shown, the fluid carrier 5 includes a retaining plate 502, which is L-shaped. The retaining plate 502 is connected to the side wall of the clamping plate 501. The retaining plate 502 and the clamping plate 501 form a receiving space 5013. The receiving space 5013 is correspondingly provided with the insertion channel 101 to receive the conductive wire 6 entering from the insertion channel 101.

[0046] In one embodiment, such as Figure 1 , Figure 5 and Figure 7As shown, the wire clamping plate 501 has a locking block 5012 and a blocking part 5014. The blocking part 5014 extends into the wire clamping hole 2025. In the locked position, the first surface of the blocking part 5014 is in contact with the first inner wall 20251 of the wire clamping hole 2025. Through the setting of the blocking part 5014, in the locked position, the first surface of the blocking part 5014 is in contact with the first inner wall 20251 of the wire clamping hole 2025. In the wire clamping position, the second surface 5011 of the blocking part 5014 cooperates with the second inner wall of the wire clamping hole 2025 to clamp the conductive wire 6. It should be noted that in this embodiment, the first surface and the second surface 5011 of the wire clamping plate 501 are respectively located on both sides of the plate body. The second surface 5011 has several parallel grooves to form an uneven surface, thereby increasing the friction between the second surface 5011 and the conductive wire 6. In this embodiment, as shown... Figure 1 As shown, the end of the snap-fit ​​end 203 has an L-shaped notch, which engages with the wire clamping hole 205.

[0047] In one embodiment, such as Figure 5 , Figure 7 As shown, the enclosure plate 502 includes a first enclosure portion 5021 and a second enclosure portion 5022. The first enclosure portion 5021 is connected to the side wall of the wire clamping plate 501. The length of the first enclosure portion 5021 is greater than the length of the second enclosure portion 5022. A gap is left between the trigger end 301 and the wire clamping plate 501, and the trigger end 301 is suspended. In this embodiment, as... Figure 7 As shown, the lengths of the first enclosure 5021 and the second enclosure 5022 are both along the Z-axis. Together, the first enclosure 5021, the second enclosure 5022, and the clamping plate 501 form a U-shaped accommodating space 5013, with the first enclosure 5021 as the bottom and the second enclosure 5022 and the clamping plate 501 as the sides. The trigger end 301 is suspended and located below the second enclosure 5022. A gap is left between the trigger end 301 and the clamping plate 501 to prevent interference when the trigger end 301 is subjected to the force of the conductive wire 6. In this embodiment, as... Figure 5 , Figure 6 As shown, there is a receiving space 5013 and a wire clamping hole 2025 between the insertion channel 101 and the trigger end 301. This arrangement allows the conductive wire 6 to enter the housing 1 with a longer length. For conductive wires with larger diameters, the effective clamping length is longer, making it less likely to fall off easily.

[0048] In one embodiment, such as Figure 2 , Figure 4As shown, the trigger plate 3 includes a first fixed end 303 and a first intermediate connecting section 302. The first fixed end 303 is fixedly connected to the housing 1. The first fixed end 303 and the trigger end 301 are respectively located on both sides of the first intermediate connecting section 302. The trigger plate 3 is arranged in a "Z" shape. A through hole 304 is provided at the third connection point between the first fixed end 303 and the first intermediate connecting section 302. It should be noted that the first fixed end 303 and the trigger end 301 are staggered, that is, the first fixed end 303 is located at one end of the first intermediate connecting section 302, and the trigger end 301 is located at the other end of the first intermediate connecting section 302, and the first fixed end 303 and the trigger end 301 are respectively located on both sides of the first intermediate connecting section 302 to form a "Z" shape. In addition, as Figure 4 As shown, the connection between the first fixed end 303 and the first intermediate connecting section 302 is arc-shaped, and the connection between the trigger end 301 and the first intermediate connecting section 302 is arc-shaped. The hole 304 is provided to allow the passage of the locking tongue plate 4.

[0049] In one embodiment, such as Figure 2 , Figure 3 , Figure 9 As shown, the latch plate 4 includes a second intermediate connecting section 402 and a second fixed end 403. The second fixed end 403 is fixedly connected to the housing 1. One end of the second intermediate connecting section 402 is connected to the latch end 401, and the other end of the second intermediate connecting section 402 is connected to the second fixed end 403. The latch end 401 is disposed through the through hole 304. When the latch end 401 is in the locked position, it is inserted into the locking hole 2011 of the locking end 201. Figure 2 As shown, the first fixed end 303 is located above the second fixed end 403 along the Z-axis direction, and is set through the through hole 304 by the locking tongue end 401. When the locking tongue end 401 is in the locked position, it is inserted into the locking hole 2011 of the locking end 201. The first surface of the blocking part 5014 is fitted against the first inner sidewall 20251 of the wire clamping hole 2025. It should be noted that, as Figure 2 As shown, the width of the second intermediate connecting section 402 along the Y-axis is less than the width of the latch end 401, and the width of the latch end 401 along the Y-axis is less than the width of the second fixed end 403, so that the second intermediate connecting section 402 serves as an effective elastic section, making it easier for the latch plate 4 to slide.

[0050] In one embodiment, such as Figure 2 , Figure 3 As shown, a shoulder 404 extends from each side of the fourth connection point between the second intermediate connecting section 402 and the latch end 401, and the shoulder 404 is adapted to abut against the third connection point. Figure 2As shown, the width of the latch end 401 along the Y-axis is less than the width of the through hole 304, and the width of the "latch end 401 + shoulder 404" along the Y-axis is greater than the width of the through hole 304, so as to prevent the shoulder 404 from entering the through hole 304. By setting two shoulders 404, the force on the latch plate 4 is more balanced and the movement process is more stable.

[0051] In one embodiment, such as Figure 5 , Figure 6 As shown, the housing 1 has a slide rail 103, and the locking end 201 slides along the slide rail 103 under drive. The housing 1 also has a limiting block 104, which abuts against the locking end 203 and / or the second connection 2024. The slide rail 103 allows the locking end 201 to reciprocate within it. The limiting block 104 restricts the arbitrary movement of the locking end 203 and the second connection 2024. In this embodiment, the housing 1 has a first fixing groove and a second fixing groove. The first fixing groove is used to fix the first fixing end 303, and the second fixing groove is used to fix the second fixing end 403, thus providing a fixing function.

[0052] A method of using a contact terminal block includes the following steps:

[0053] (1) When in the locked position, the first inner wall 20251 of the wire clamping hole 2025 is fitted with the first surface of the wire clamping plate 501, and the locking tongue end 401 passes through the through hole 304 and enters into the locking hole 2011 to realize the locking tongue end 401 and the locking end 201 locking, and the intermediate drive section 202 is in a compressed state.

[0054] (2) When moving from the locked position to the clamped position, the conductive wire 6 passes through the insertion channel 101, the clamped hole 2025, and the receiving space 5013 in sequence and then abuts against the trigger end 301. The end of the conductive wire 6 applies a downward force F along the Z-axis to the suspended trigger end 301. The trigger end 301 drives the first intermediate connecting section 302 to move downward. The first intermediate connecting section 302 drives the shoulder 404 to move downward. The shoulder 404 drives the locking tongue end 401 to move downward. Through the force-saving lever method, the locking tongue end 401 slides out of the locking hole 2011. Under the action of the restoring force of the intermediate driving section 202, the locking end 201 moves towards the intermediate driving section 202.

[0055] (3) When in the clamping position, the second inner wall of the clamping hole 2025 clamps the conductive wire 6 with the second surface 5011 of the clamping plate 501, and the intermediate driving section 202 is in a free state.

[0056] (4) When moving from the clamping position to the locking position, the button enters the drive channel 102. The button applies force to the first connection 2023 to drive the first intermediate drive segment 2021 toward the locking end 201. After the conductive wire 6 is no longer clamped, it can be pulled out to the outside of the housing 1. Under the guiding action of the bending setting, the locking end 201 allows the locking tongue end 401 to smoothly enter the locking hole, realizing the locking tongue end 401 and the locking end 201 locking.

[0057] It should be noted that the clamping position in this embodiment has two states, one of which is... Figure 8 The state shown is the one where the conductive wire 6 is not inserted; another is... Figure 10 The state of the clamped conductive wire 6 after it has been inserted is shown.

[0058] The contact terminal block provided by this utility model has the following advantages: (1) By setting the central axis of the channel and the central axis of the drive channel 102 parallel, the insertion channel 101 and the drive channel 102 are located on the same side of the housing 1, and the direction of button entry, the insertion direction of the conductive wire 6 and the direction of opening the cage spring 2 are the same, making it more convenient for users to connect wires in the relatively small housing 1; (2) By setting the bend of the locking end 201, the locking tongue end 401 and the locking hole 2011 are more smoothly engaged; (3) By setting the shoulder 404, the locking tongue plate 4 is more balanced in force and the movement process is more stable; (4) By setting the trigger plate 3 as Z-shaped, the locking tongue end 401 is driven to slide by the lever method. (5) A U-shaped receiving space 5013 is provided on the carrier fluid 5 to prevent the conductive wire 6 from shaking arbitrarily in the housing 1; (6) The housing 1 is provided with a first fixing groove and a second fixing groove. The first fixing end 303 is fixed in the first fixing groove and the second fixing end 403 is fixed in the second fixing groove, so that the locking tongue plate 4 and the trigger plate 3 are more firmly fixed; (7) There is a receiving space 5013 and a wire clamping hole 2025 between the insertion channel 101 and the trigger end 301. This setting makes the length of the conductive wire 6 entering the housing 1 longer. For the conductive wire 6 with a larger diameter, the effective clamping length is longer and it is not easy to fall off easily.

[0059] As an alternative implementation, the central axis of the insertion channel 101 and the central axis of the drive channel 102 can also be set at an angle, with the angle being less than 90°. That is, the insertion channel 101 and the drive channel 102 are not set in parallel, but can be set at an angle. The insertion channel 101 and the drive channel 102 can be considered to be set on the same side if they are located on the same side of the housing.

[0060] As an alternative embodiment, the locking end 201 may not be provided with a locking hole 2011. The locking end 201 is provided with a locking groove, and the locking tongue end 401 is engaged with the locking groove to achieve snap connection.

[0061] As an alternative embodiment, the locking end 201 is provided with a locking groove, and the locking tongue plate 4 extends into the locking groove in the locking position.

[0062] As an alternative embodiment, the enclosing plate 502 is "U"-shaped, and the enclosing plate 502 and the wire clamping plate 501 form a "mouth"-shaped accommodating space 5013.

[0063] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
