Description

A type of fence-type terminal block Technical Field

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

[0002] In the field of electrical connections, barrier terminal blocks are widely used in various electrical equipment and circuit systems due to their advantages such as reliable connection and convenient operation. Traditional barrier terminal blocks typically consist of an insulating base, connecting plates, crimping plates, and fixing bolts. The connecting plates and crimping plates are secured to the terminal slots of the insulating base by the fixing bolts to achieve electrical connection.

[0003] However, in practical use, it has been found that when the fixing bolts are loosened for wiring adjustments or maintenance, the crimping tabs are easily detached and lost from the terminal slot. Once the crimping tabs are lost, it affects the normal use of the terminal blocks. Therefore, there is an urgent need for a simple and reliable technical solution to solve the problem of easily lost crimping tabs and improve the safety and convenience of using barrier-type terminal blocks. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a fence-type terminal block.

[0005] The technical solution adopted by this utility model is: a fence-type terminal block, including an insulating base, a connecting piece, a crimping piece, and a fixing bolt. Terminal slots are equally spaced along the length of the insulating base. The connecting piece and the crimping piece are stacked in the terminal slots. The connecting piece is provided with a threaded hole for threaded connection with the screw of the fixing bolt. The crimping piece is provided with a through hole for the screw of the fixing bolt to pass through. Guide blocks are provided at both ends of the crimping piece. Guide grooves that slide with the guide blocks are provided on the side walls of the terminal slots. The guide grooves include an entrance section extending from the opening of the guide groove into the guide groove and a vertical section communicating with the entrance section.

[0006] Furthermore, the entrance section and the vertical section form an "L" shape.

[0007] Furthermore, the two adjacent end faces of the connector and the crimping piece are provided with arc-shaped crimping grooves.

[0008] Furthermore, the terminal slots are arranged in two rows, with five terminal slots in each row, and the terminal slots are separated from each other by inter-slots.

[0009] Furthermore, the insulating base has fixed steps extending from both ends, and fixed holes are provided on the fixed steps.

[0010] Furthermore, the bottom of the connector extends to a mounting portion, the outer wall of the mounting portion is a frustum structure, the bottom of the mounting portion extends to a support leg, the bottom of the terminal slot is provided with a frustum groove that is interference-fitted with the mounting portion, and the bottom of the frustum groove is provided with a support leg opening for the support leg to pass through.

[0011] Furthermore, the support leg is provided with a connection hole.

[0012] The beneficial effects of this utility model are:

[0013] First, when the fixing bolts are loosened for line adjustment or maintenance, the crimping piece will not easily detach from the terminal slot due to the sliding fit between the guide block and the guide groove. It can only be removed by sliding out along a specific path of the guide groove, which reduces the risk of accidental loss of the crimping piece, ensures the integrity and normal use of the wiring terminal, and avoids electrical connection system failure due to loss of the crimping piece.

[0014] Second, this structural design prevents the loss of the crimping plate without adding too much complexity to the structure. The installation and disassembly process is still convenient and meets the actual operation requirements. The structure of this application is simple, the production cost is lower, and it is easy to promote and apply on a large scale.

[0015] Third, the characteristic that the crimping tabs are not easily lost significantly improves the safety and convenience of using the fence-type terminal block, and enhances the stability and reliability of the entire electrical connection system during the long-term operation of electrical equipment and circuit systems.

[0016] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides a fence-type terminal block.

[0025] In this embodiment, referring to Figures 1-4, the fence-type terminal block includes an insulating base 1, a connecting piece 2, a crimping piece 3, and a fixing bolt 4. Terminal slots 5 are evenly spaced along the length of the insulating base. The connecting piece and the crimping piece are stacked in the terminal slots 5. The connecting piece 2 is provided with a threaded hole 6 that is threaded to the screw of the fixing bolt. The crimping piece is provided with a through hole 7 for the screw of the fixing bolt to pass through. Guide blocks 8 are provided at both ends of the crimping piece. Guide slots 9 that slide with the guide blocks 8 are provided on the side walls of the terminal slots. The guide slots 9 include an entrance section 10 extending from the opening of the guide slot into the guide slot and a vertical section 11 communicating with the entrance section 10.

[0026] In the above technical solution, based on the traditional fence-type terminal block, guide blocks are added to both ends of the crimping piece, and guide grooves are set on both side walls of the terminal slot. The guide grooves are designed to include an entry section and a vertical section. When the fixing bolts are loosened, the sliding fit between the guide blocks and the guide grooves restricts the movement path of the crimping piece. Only by sliding along the specific entry and vertical sections can the crimping piece be removed from the terminal slot. This effectively prevents the crimping piece from accidentally falling off or being lost when the fixing bolts are loosened for circuit adjustment or maintenance, ensuring the integrity and normal use of the terminal block.

[0027] Specifically, the entrance section and the vertical section form an "L" shape.

[0028] In this embodiment, the guide groove adopts an "L" shaped structure. When sliding out, it needs to slide from the vertical section to the entrance section before sliding out, which improves the reliability of preventing loss.

[0029] Specifically, the two adjacent end faces of the connector and the crimping piece are provided with arc-shaped crimping grooves 12.

[0030] In this embodiment, arc-shaped crimping grooves are provided on the adjacent end faces of the connector and crimping plate. During the wiring process, the wire or cable is clamped in the crimping groove.

[0032] In this embodiment, the terminal slots are arranged in double rows, with five slots in each row, separated by interslots. The double-row, high-quantity terminal slot design effectively utilizes the space of the insulating base and increases the number of terminals that can be connected. The interslots serve as physical separators, preventing interference between the connecting pieces and crimping pieces in adjacent terminal slots and ensuring the independence and normal function of each terminal slot.

[0033] Specifically, the insulating base has fixed steps 14 extending from both ends, and fixed holes 15 are provided on the fixed steps 14.

[0034] In this embodiment, the insulating base extends into fixed steps at both ends, and fixing holes are provided on the fixed steps. When installing the terminal block, screws, bolts, or other connectors can be used through the fixing holes to firmly fix the terminal block to the electrical equipment or circuit board. Stable installation is achieved by utilizing the supporting surface provided by the fixed steps and the connecting effect of the fixing holes.

[0035] Specifically, the bottom of the connector extends into a mounting portion 16, the outer wall of the mounting portion 16 is a frustoconical structure, the bottom of the mounting portion extends into a support leg 17, the bottom of the terminal slot is provided with a frustoconical groove 18 that is interference-fitted with the mounting portion, and the bottom of the frustoconical groove is provided with a support leg opening 19 for the support leg to pass through.

[0036] In this embodiment, the bottom of the connector extends into a mounting portion with a frustum-shaped outer wall, and the bottom of the mounting portion has a support foot. The bottom of the terminal slot is correspondingly provided with a frustum-shaped groove and a support foot opening. During installation, the mounting portion and the frustum-shaped groove are interference-fitted. Utilizing the gradually tightening characteristics of the frustum structure, a tight connection is formed between the connector and the terminal slot, ensuring a stable connection and easy disassembly.

[0037] Specifically, the support leg is provided with a connection hole 20.

[0038] In this embodiment, a connection hole is provided on the support leg. The connection hole can be used to pass through a connector, such as a pin or bolt, to make additional connection and fixation between the terminal block and other components (such as a circuit board or a fixed bracket).
