Description

Technical Field

[0001] This utility model relates to the field of terminal housing technology, and specifically to a terminal housing that can improve the stability of wires. Background Technology

[0002] Terminal housings, also known as plastic housings or insulating housings, are an indispensable part of connector structures. They are typically made of insulating materials, such as plastic, and are used to enclose and protect the internal terminals of the connector. The role of terminal housings is particularly important in the transmission of low-voltage signals, currents, and voltages, as they effectively isolate external environmental interference from signal, current, and voltage transmission, ensuring the integrity and stability of these signals, currents, and voltages.

[0003] The current casing requires repeated checks to ensure the wires are properly inserted during installation due to design flaws or lack of operator experience, increasing the workload for operators. Furthermore, the lack of a fixed structure means that the wires may come loose when subjected to external forces such as pulling or vibration, potentially leading to circuit malfunctions and failing to meet usage requirements. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a terminal housing that improves the stability of wires. It has a simple structure, is easy to use, ensures that the wires are inserted properly, improves the tensile strength of the wires, avoids the risk of circuit failure, and meets the usage requirements.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A terminal housing that can improve the stability of wires includes a housing, the interior of which is provided with a plurality of terminal slots. Each terminal slot has an inlet hole and an outlet hole at its two ends. The inlet hole is provided with a guide groove and a detachable back cover. The back cover is provided with an arc-shaped groove that fits the outer wall of the wire. The arc-shaped groove and the guide groove are arranged opposite to each other. When the back cover is installed at the inlet hole, a clamping space for the wire is formed between the guide groove and the arc-shaped groove.

[0007] Furthermore, both ends of the back cover are provided with slots, and the housing is provided with clips that fit the slots. Through the cooperation of the slots and clips, the back cover can be detachably installed on the housing.

[0008] Furthermore, arc-shaped grooves are provided on both sides of the back cover, and reinforcing ribs are provided at the upper end of the back cover.

[0009] Furthermore, the housing is provided with several positioning posts, which are connected to the terminal slots.

[0010] The beneficial effects of this utility model are as follows: A guide groove and a detachable back cover are provided at the wire inlet. The guide groove at the wire inlet guides the wire to accurately align with the inlet, preventing the wire from shifting or tilting during insertion, allowing the wire to enter the terminal slot more smoothly and effectively solving the problem of incomplete wire insertion. The back cover has an arc-shaped groove that fits the outer wall of the wire. The arc-shaped groove and the guide groove are arranged opposite each other. When the back cover is installed at the wire inlet, a clamping space for the wire is formed between the guide groove and the arc-shaped groove. The arc-shaped groove that fits the outer wall of the wire can accurately position the wire. When the back cover is installed... Subsequently, the clamping space formed by the arc-shaped groove and the guide groove restricts the wire to a specific position, further ensuring that the wire is on the correct path when inserted, without swaying or deviating, thus ensuring that the wire can be accurately inserted into the terminal slot. At the same time, the arc-shaped groove fits tightly against the outer wall of the wire, increasing the contact area and friction between the wire and the terminal housing. When an external force pulls on the wire, the greater friction can effectively resist the pulling force, preventing the wire from being easily pulled out, thereby enhancing the reliability of the connection between the wire and the terminal, enhancing its tensile strength, avoiding the risk of circuit failure, and meeting the usage requirements.

[0017] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments:

[0018] This embodiment: as follows Figure 1-5As shown, a terminal housing that can improve the stability of wires includes a housing 10, and the interior of the housing 10 is provided with a plurality of terminal slots 11, and the two ends of the terminal slots 11 are respectively provided with inlet holes and outlet holes.

[0019] The inlet hole is provided with a guide groove 12 and a detachable back cover 20. The guide groove 12 at the inlet hole can guide the wire 30 to be accurately aligned with the inlet hole, avoiding the wire 30 from shifting or tilting during the insertion process, so that the wire 30 can enter the terminal slot 11 more smoothly, effectively solving the problem of wire not being inserted in place.

[0020] Both ends of the back cover 20 are provided with slots 21, and the housing 10 is provided with a locking block 13 that matches the slots 21. Through the cooperation of the slots 21 and the locking buckle, the back cover 20 can be detachably installed on the housing 10. The back cover 20 is provided with several arc-shaped grooves 22 that match the outer wall of the wire. The arc-shaped grooves 22 are respectively provided on the two side walls of the back cover 20. The upper end of the back cover 20 is provided with a reinforcing rib 23, which is located between the arc-shaped grooves 22 on the two side walls. The reinforcing rib 23 located at the upper end of the back cover 20 between the arc-shaped grooves 22 on the two side walls can enhance the overall structural strength of the back cover 20, improve the back cover 20's resistance to deformation, and enable it to maintain a good shape and performance when subjected to external impact or compression, and is not prone to cracking or damage. The arc-shaped grooves 22 and the guide grooves 12 are arranged opposite to each other. When the back cover 20 is installed at the wire inlet hole, the guide grooves 12 and the arc-shaped grooves 22 form a clamping space for the wire.

[0021] The arc-shaped groove 22, which is adapted to the outer wall of the wire 30, can accurately position the wire 30. After the back cover 20 is installed, the clamping space formed by the arc-shaped groove 22 and the guide groove 12 restricts the wire 30 to a specific position, further ensuring that the wire 30 is in the correct path when inserted and will not shake or deviate at will, thereby ensuring that the wire can be accurately inserted into the terminal slot. At the same time, the arc-shaped groove 22 fits tightly with the outer wall of the wire 30, increasing the contact area and friction between the wire 30 and the housing 10. When an external force pulls the wire 30, the greater friction can effectively resist the pulling force and prevent the wire 30 from being easily pulled out, thereby enhancing the reliability of the connection between the wire 30 and the terminal, enhancing its tensile strength, avoiding the risk of circuit failure, and meeting the usage requirements.

[0022] The housing 10 is provided with a number of positioning posts 14, which are connected to the terminal slot 11. The positioning posts 14 can provide accurate positioning for the terminals inserted into the terminal slot 11, ensuring that the terminals are in the correct position and orientation when inserted, preventing the terminals from being misaligned or not in place, which helps to improve the accuracy and reliability of the connection between the terminals and the slot, and ensures the stability of the electrical connection.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
