Description

Technical Field

[0001] This utility model relates to the field of terminal block housings, specifically a terminal block housing. Background Technology

[0002] The terminal block housing is a component used to protect the internal parts of the terminal block. Its function is to protect the insulators, contacts and other parts inside the terminal block from damage. The positioning keyway on it can ensure the correct positioning of the plug and socket, and also has a certain electromagnetic shielding effect, which can reduce the impact of electromagnetic interference on the signal transmission of the terminal block.

[0003] In existing technology, the outer shell and the limiting plate are generally connected by a locking block. After the locking is completed, if disassembly is required, it can only be done by brute force. After being disassembled by brute force, the locking block used for the locking is prone to irreversible deformation, which will lead to damage to the limiting plate and make it unusable. Utility Model Content

[0006] As a further improvement of this utility model: one end of the inner wall of the insertion groove is integrally formed with an extrusion slope, and the inclination of the plastic elastic block matches the inclination of the extrusion slope.

[0007] As a further embodiment of this utility model: the synchronous unlocking mechanism includes a sliding rod axially slidably installed inside the back plate of the outer shell body, a synchronous push plate is fixedly installed at one end of the sliding rod located on the back of the outer shell body, and a pressing plate is fixedly installed at one end of the sliding rod located at the front of the outer shell body.

[0008] As a further improvement of this utility model: the end of the extrusion plate near the plastic elastic block is in contact with the plastic elastic block.

[0009] As a further improvement of this utility model, the back plate of the outer shell body is provided with a circular hole for the sliding rod to slide.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting up a synchronous unlocking mechanism, multiple plastic elastic blocks can be unlocked simultaneously, which facilitates the disassembly of the limit plate without the need for brute force, thus avoiding damage caused by brute force disassembly.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the utility model, a terminal block housing includes a housing body 1. A limiting groove 2 is formed on the top of the protruding plate of the housing body 1. A limiting plate 3 is inserted into the inner wall of the limiting groove 2. An insertion groove 4 is formed on the top of the back plate of the housing body 1. A downward protruding insertion block 7 is integrally formed on the back end of the limiting plate 3. A plastic elastic locking block 8 that is inclined upward is integrally formed on the bottom end of the insertion block 7. A synchronous unlocking mechanism extending to the front end of the back plate of the housing body 1 is slidably installed on the outside of the back plate of the housing body 1. A pressing slope 9 is integrally formed on one end of the inner wall of the insertion groove 4. The inclination of the plastic elastic locking block 8 matches the inclination of the pressing slope 9.

[0015] In this embodiment: After the components to be installed inside the outer shell 1 are installed, the limiting plate 3 is inserted into the limiting groove 2. At this time, the limiting plate 3 drives the plug block 7 to be inserted into the plug groove 4. The plug block 7 drives the plastic elastic locking block 8 to contact the extrusion slope 9. At this time, the plastic elastic locking block 8 applies extrusion force to the extrusion slope 9. At this time, the plastic elastic locking block 8 deforms until the plastic elastic locking block 8 and the extrusion slope 9 are misaligned. At this time, the plastic elastic locking block 8 performs elastic reset, realizing the snap-fit ​​installation of the limiting plate 3. When disassembling the limiting plate 3, by pushing the synchronous unlocking mechanism, the synchronous unlocking mechanism simultaneously applies pressure to multiple plastic elastic blocks 8, squeezing and deforming the plastic elastic blocks 8, at which point the limiting plate 3 can be pulled upward.

[0016] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The synchronous unlocking mechanism includes a sliding rod 5 axially slidably installed inside the back plate of the outer shell body 1. A synchronous push plate 6 is fixedly installed at one end of the sliding rod 5 on the back of the outer shell body 1. A pressing plate 10 is fixedly installed at one end of the sliding rod 5 on the front of the outer shell body 1. The end of the pressing plate 10 close to the plastic elastic block 8 is in contact with the plastic elastic block 8. A round hole for the sliding rod 5 to slide is opened inside the back plate of the outer shell body 1.

[0017] In this embodiment: when disassembling the limiting plate 3, the synchronous push plate 6 is pushed to move towards the sliding rod 5. The synchronous push plate 6 pushes the sliding rod 5 to move synchronously. At this time, the sliding rod 5 moves along the round hole, and the sliding rod 5 pushes the plastic elastic block 8 to deform until the plastic elastic block 8 and the extrusion inclined surface 9 are completely misaligned. At this time, the limiting plate 3 can be pulled out upwards, so as to facilitate the installation and disassembly of the limiting plate 3.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
