Description

Technical Field

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

[0002] Terminal blocks are widely used in various electrical equipment, such as low-voltage switchgear, for connecting and disconnecting wires. Existing terminal blocks typically involve inserting stripped wires into the terminal's port and then securing the wires with screws. Due to their small size, these terminals can only be inserted and removed by pinching them with the index finger and thumb, resulting in a small contact area and making them difficult to insert and remove. Furthermore, the exposed conductive wire at the rear end of the terminal block makes it easy for users to pull it out by gripping the wire, reducing the stability between the conductive wire and the terminal block and hindering subsequent conductive connections.

[0003] Generally speaking, the production of the shell requires two sets of molds to produce the male shell and the female shell respectively. The design of the male shell and the female shell can wrap the necessary accessories inside the shell during assembly. However, the cost of two sets of molds is relatively high, which is not conducive to saving production costs.

[0004] Therefore, it is necessary to propose a connector housing to be attached to the terminal block to protect the conductive wires at the rear end of the terminal block, provide sufficient gripping area for easy insertion and removal of the terminal block, and at the same time reduce production costs. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a connector housing to be attached to the terminal block to protect the conductive wires at the rear end of the terminal block and provide sufficient gripping area for easy insertion and removal of the terminal block, while also reducing production costs.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a connector housing, including two complementary shells, which are centrally symmetrical and fixedly connected. Each complementary shell has a receiving groove for storing wires, and one end of each complementary shell has a clamping plate for clamping terminals. The two clamping plates are symmetrically arranged.

[0008] Furthermore, one side of the complementary shell is provided with a snap-fit ​​plate and a first limiting groove, the first limiting groove being located on one side of the snap-fit ​​plate, and the other side of the complementary shell is provided with a snap-fit ​​groove and a first limiting plate, the first limiting plate being located on one side of the snap-fit ​​groove, the snap-fit ​​plate corresponding to the snap-fit ​​groove and forming a snap-fit ​​connection, and the first limiting plate corresponding to the first limiting groove and being housed within the first limiting groove.

[0009] Furthermore, the snap-fit ​​plate is provided with a first snap-fit ​​protrusion, and the snap-fit ​​groove is provided with a second snap-fit ​​protrusion, the first snap-fit ​​protrusion abutting against the second snap-fit ​​protrusion.

[0010] Furthermore, the length of the snap-fit ​​plate is the same as the depth of the snap-fit ​​groove.

[0011] Furthermore, a second limiting plate is provided on one side of the complementary shell, and a second limiting groove is provided on the other side of the complementary shell. The second limiting plate corresponds to the second limiting groove and is accommodated in the second limiting groove.

[0012] Furthermore, the second limiting plate and the first limiting groove are both located on the same side of the complementary shell.

[0013] Furthermore, the second limiting groove and the first limiting plate are both located on the same side of the complementary shell.

[0015] Furthermore, the clamping plate is provided with a hook-and-loop protrusion structure, which is perpendicular to the clamping plate.

[0016] Furthermore, the clamping plate is provided with an embedding boss for embedding wiring terminals.

[0017] The beneficial effects of this utility model are:

Only one mold is needed for production, reducing production costs. The receiving groove allows for the storage of the conductive wire at the rear end of the terminal block, while two symmetrically arranged clamping plates securely hold and fix the terminal block. During insertion and removal, the user can hold the two complementary shells without pulling on the conductive wire at the rear end, making it convenient and quick. In summary, this connector shell effectively attaches to the terminal block to protect the conductive wire at the rear end, provides sufficient gripping area for easy insertion and removal, and also reduces production costs.

Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0024] Please refer to Figures 1-2 This utility model proposes a connector housing, including two complementary shells 1, which are centrally symmetrical and fixedly connected. The complementary shell 1 is provided with a receiving groove 2 for storing wires, and one end of the complementary shell 1 is provided with a clamping plate 3 for clamping the terminal block. The two clamping plates 3 are symmetrically arranged.

[0025] In this embodiment, two complementary shells 1 of the same shape are used to cover and protect the conductive wire at the rear end of the terminal block. Only one mold is needed to complete the production, which reduces the production cost. At the same time, the receiving groove 2 can store the conductive wire at the rear end of the terminal block. After the two complementary shells 1 are covered, the two receiving grooves 2 form a closed space to store the conductive wire. The two symmetrically arranged clamping plates 3 can firmly clamp and fix the terminal block. When plugging and unplugging, the user can hold the two complementary shells 1 by hand to plug and unplug without pulling the conductive wire at the rear end, which is convenient and quick.

[0026] In summary, the connector housing can be effectively attached to the terminal block to protect the conductive wires at the rear of the terminal block, provide sufficient gripping area for easy insertion and removal of the terminal block, and also reduce production costs.

[0027] In this embodiment, one side of the complementary shell 1 is provided with a snap-fit ​​plate 11 and a first limiting groove 12, with the first limiting groove 12 located on one side of the snap-fit ​​plate 11. The other side of the complementary shell 1 is provided with a snap-fit ​​groove 13 and a first limiting plate 14, with the first limiting plate 14 located on one side of the snap-fit ​​groove 13. The snap-fit ​​plate 11 corresponds to the snap-fit ​​groove 13 and forms a snap-fit ​​connection, while the first limiting plate 14 corresponds to the first limiting groove 12 and is housed within the first limiting groove 12. When assembling the two complementary shells 1, the clamping plate 3 of one of them is first aligned with one side of the wiring terminal, and then the... The other complementary shell 1 is closed. During the closing process, the two clamping plates 3 clamp and fix the wiring terminals. The snap-fit ​​plate 11 on one complementary shell 1 will snap and fix with the snap-fit ​​groove 13 on the other complementary shell 1. The first limiting plate 14 on one complementary shell 1 will be inserted into the first limiting groove 12 on the two complementary shells 1, so that the two complementary shells 1 form a fixed connection. The cooperation between the first limiting groove 12 and the first limiting plate 14 is to prevent the two complementary shells 1 from being misaligned when connected, thereby improving the accuracy and convenience of connection.

[0028] In this embodiment, the snap-fit ​​plate 11 is provided with a first snap-fit ​​protrusion 111, and the snap-fit ​​groove 13 is provided with a second snap-fit ​​protrusion 131. The first snap-fit ​​protrusion 111 and the second snap-fit ​​protrusion 131 abut against each other. After the snap-fit ​​plate 11 is inserted into the snap-fit ​​groove 13, the first snap-fit ​​protrusion 111 and the second snap-fit ​​protrusion 131 abut against each other, so that the snap-fit ​​plate 11 and the snap-fit ​​groove 13 form a snap-fit ​​connection.

[0029] In this embodiment, the length of the snap-fit ​​plate 11 is the same as the depth of the snap-fit ​​groove 13, so that when the two complementary shells 1 are connected, there will be no structure protruding to the outside.

[0030] In this embodiment, a second limiting plate 15 is provided on one side of the complementary shell 1, and a second limiting groove 16 is provided on the other side of the complementary shell 1. The second limiting plate 15 corresponds to the second limiting groove 16 and is housed within the second limiting groove 16. When the two complementary shells 1 are connected, the second limiting plate 15 is inserted into the second limiting groove 16. The cooperation between the second limiting plate 15 and the second limiting groove 16 prevents the two complementary shells 1 from being misaligned during connection, thereby improving the accuracy and convenience of connection.

[0031] In this embodiment, the second limiting plate 15 and the first limiting groove 16 are both located on the same side of the complementary shell 1. Since the complementary shell 1 is centrally symmetrical, the second limiting plate 15 and the first limiting plate 12 are distributed at staggered positions, which also balances the force on the complementary shell 1 and improves the stability when the two complementary shells 1 are assembled.

[0032] In this embodiment, the second limiting groove 16 and the first limiting plate 12 are both located on the same side of the complementary shell 1. Since the complementary shell 1 is centrally symmetrical, the second limiting groove 16 and the first limiting groove 16 are distributed at staggered positions, which also balances the force on the complementary shell 1 and improves the stability when the two complementary shells 1 are assembled.

[0033] In this embodiment, one end of the complementary shell 1 is provided with a wire-passing half-groove 17, and the two wire-passing half-grooves 17 are connected and merged to form a wire-passing groove 4; the wire-passing groove 4 is used to provide a channel for bundling and placing the wires at the rear end of the terminal block, which facilitates wire management.

[0034] In this embodiment, the clamping plate 3 is provided with a hooking protrusion structure 31, which is perpendicular to the clamping plate 3. When the complementary shell 1 is assembled with the terminal block, the hooking protrusion structure 31 hooks onto the corner of the terminal block. When the two clamping plates 3 clamp the terminal block at the same time, the hooking protrusion structures 31 at both locations clamp and hook the terminal block together to securely clamp and fix the terminal block, so that the terminal block and the two complementary shells 1 are combined into an integral structure.

[0035] In this embodiment, the clamping plate 3 is provided with an embedding boss 32 for embedding the terminal block; when the complementary shell 1 is assembled with the terminal block, the embedding boss 32 can be embedded into the screw hole of the terminal block. When the terminal block is used to fix the conductive wire, the conductive wire is clamped by the screw, and the screw sinks down, leaving the screw hole empty. The embedding boss 32 can then be embedded into the empty screw hole to improve the clamping and fixing force of the clamping plate 3 on the terminal block.

[0036] In this embodiment, the outer surface of the complementary shell 1 is provided with anti-slip texture 18 for gripping and anti-slip.

[0037] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
