Description

Technical Field

[0001] This application relates to the field of terminal block fittings, and more particularly to a housing and electrical connector. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They serve to connect wires in electronic devices, circuit boards, or electrical systems, facilitating electrical connections. In some applications, terminal blocks require protection using electrical connectors. An electrical connector is a container or housing used in electrical wiring installations to house, organize, and protect the terminal blocks. Testing electrical connectors is a crucial step in ensuring the safety and proper functioning of electrical wiring installations.

[0003] Existing electrical connectors lack dedicated apertures for easy testing, so other electrical components within the housing may obstruct the path between the test probes and the wire under test. Furthermore, technicians must hold both probes in place during testing, making data reading more difficult.

[0004] In related technologies, electrical connectors with test holes have been developed. However, in actual testing, due to the obstruction of the electrical connector housing, technicians cannot directly see the position of the wiring terminals inside the electrical connector. Therefore, when inserting the test probe into the electrical connector through the test hole, there is a need to improve how to quickly make the test probe contact the wiring terminals. Utility Model Content

[0005] To facilitate contact between the testing probe and the wiring terminal, in a first aspect, this application provides an upper housing.

[0006] The upper shell provided in this application adopts the following technical solution: An upper shell includes a connecting plate and a plurality of connectors; the connecting plate has a plurality of through holes spaced apart along its own length; each connector is disposed in each of the through holes; each connector includes a plurality of elastic strips, the plurality of elastic strips are spaced apart circumferentially along the through holes, the upper end of the elastic strips is disposed on the hole wall of the through hole, a clamping hole is formed between the plurality of elastic strips, and the upper end of the elastic strips is bent.

[0007] By adopting the above technical solution, in practical applications, the detection probe is inserted into the clamping hole formed by multiple elastic strips. Under the elastic action of multiple elastic strips, the detection probe is clamped and fixed. Since the upper end of each elastic strip is bent, the diameter of the upper end of the clamping hole is larger, which guides the insertion of the detection probe, thereby facilitating the contact between the detection probe and the terminal block. It can also ensure the service life of the elastic strip while facilitating the elastic deformation of the elastic strip.

[0008] Preferably, the connecting plate has a through groove between two adjacent connecting heads.

[0009] By adopting the above technical solution and setting through grooves, the material used in the connecting plate is reduced, and two adjacent corresponding elastic strips are connected to facilitate the elastic deformation of the connector, thereby facilitating the contact between the detection probe and the wiring terminal.

[0010] Preferably, the connector further includes a connecting ring, which is disposed at the lower end of the plurality of elastic strips.

[0011] By adopting the above technical solution and setting a connecting ring to connect the lower ends of multiple elastic strips, the overall strength of the connector structure is ensured.

[0012] Preferably, the lower end of the connecting ring is provided with a rounded corner.

[0013] By adopting the above technical solution and setting rounded corners, contact with components in the wiring terminals can be avoided as much as possible, and the electrical detection of the wiring terminals by the detection probe can be guided to accurately realize the installation of the detection probe.

[0014] Secondly, this application provides an electrical connector.

[0015] The electrical connector provided in this application adopts the following technical solution: An electrical connector comprising the upper housing described above.

[0016] Preferably, the mounting shell further includes a lower shell, the upper shell further includes a housing, the housing is disposed on the lower shell, and the connecting plate is disposed on the housing.

[0017] By adopting the above technical solution, and by setting up a lower shell and a housing, the components of the wiring terminals can be installed.

[0018] Preferably, one end of the housing is rotatably connected to the lower housing, and the other end is snapped into the lower housing.

[0019] By adopting the above technical solution, one end of the housing is rotatably connected to the lower housing, and the other end is snapped into the lower housing, so as to facilitate the installation and disassembly of the housing.

[0020] Preferably, the mounting housing further includes a baffle plate rotatably connected to the housing to shield the plurality of connectors.

[0021] By adopting the above technical solution and setting baffles to shield each connector, dust can be prevented from entering the lower housing as much as possible.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The detection probe is inserted into the clamping hole formed by multiple elastic strips. Under the elastic action of multiple elastic strips, the detection probe is clamped and fixed. Due to the bending of the upper end of each elastic strip, the diameter of the upper end of the clamping hole is larger, which guides the insertion of the detection probe, thereby facilitating the contact between the detection probe and the terminal block. It can also ensure the service life of the elastic strip while facilitating the elastic deformation of the elastic strip. 2. By setting connecting rings to connect the lower ends of multiple elastic bars, the overall strength of the connector structure is ensured; 3. By setting rounded corners, contact with components in the wiring terminals can be avoided as much as possible, and the detection probe can be guided to perform electrical testing on the wiring terminals to accurately achieve the installation of the detection probe.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses an upper shell.

[0029] Reference Figure 1 and Figure 2 The upper shell includes a connecting plate 1 and multiple connectors 2. The connecting plate 1 is rectangular and has multiple through holes 11 evenly spaced along its length. The number of connectors 2 is the same as the number of through holes 11, and each connector 2 is located at each through hole 11. Specifically, each connector 2 includes multiple elastic strips 21, which are evenly spaced along the circumference of the through holes 11. The upper end of each elastic strip 21 is integrally connected to the connecting plate 1 at the hole wall of the through hole 11. A clamping hole 22 is formed between the multiple elastic strips 21, and the upper end of each elastic strip 21 is bent to enlarge the upper end of the clamping hole 22, i.e., the upper end of the clamping hole 22 is larger.

[0030] In practical applications, the detection probe passes through the clamping hole 22 formed by multiple elastic strips 21. Under the elastic action of the multiple elastic strips 21, the detection probe can be clamped and fixed. Because the upper end of each elastic strip 21 is bent, the upper diameter of the clamping hole 22 is set to be relatively large, guiding the insertion of the detection probe and facilitating contact between the detection probe and the terminal block. Simultaneously, when the detection probe is clamped in the clamping hole 22, the upper end of the elastic strip 21, connected to the through hole 11, experiences minimal deformation. This ensures the service life of the elastic strip 21 while facilitating its elastic deformation.

[0031] In some embodiments, the connecting plate 1 has a through groove 12 between two adjacent connectors 2, which can reduce the material used in the connecting plate 1, thereby reducing the service life of the connectors 2, and connecting two adjacent corresponding elastic strips 21 to facilitate the elastic deformation of the connectors 2, thereby facilitating the contact between the detection probe and the terminal block.

[0032] In some embodiments, the connector 2 further includes a connecting ring 23, which is integrally connected to the lower ends of the plurality of elastic strips 21 to connect and fix the lower ends of the plurality of elastic strips 21, thereby ensuring the strength of the overall structure of the connector 2 and improving the stability of the connector 2 in use.

[0033] In some embodiments, the lower end of the connecting ring 23 is provided with a rounded corner 24, which can minimize contact with the components in the terminal block and guide the electrical detection of the terminal block by the detection probe to accurately install the detection probe.

[0034] The implementation principle of this embodiment is as follows: In practical applications, the detection probe passes through the clamping hole 22 formed by multiple elastic strips 21. Under the elastic action of the multiple elastic strips 21, the detection probe can be clamped and fixed. Because the upper end of each elastic strip 21 is bent, the diameter of the upper end of the clamping hole 22 is set to be relatively large, guiding the insertion of the detection probe and facilitating contact between the detection probe and the terminal block. Simultaneously, when the detection probe is clamped in the clamping hole 22, the upper end of the elastic strip 21 connected to the through hole 11 deforms minimally, thus ensuring the service life of the elastic strip 21 while facilitating its elastic deformation.

[0035] This application discloses an electrical connector.

[0036] Reference Figure 3 and Figure 4 The electrical connector includes a lower shell 3 and an upper shell. The lower shell 3 is used to install the various components of the terminal block. The upper shell also includes a housing 4, which is installed on the lower shell 3 to enable the installation of the terminal block components. The connecting plate 1 is integrally connected to the lower shell 3 to enable the installation of the upper shell.

[0037] Reference Figure 3 In some embodiments, one end of the housing 4 is rotatably connected to the lower housing 3, and the other end of the housing 4 has protruding inserts 41 on both sides, with locking blocks 42 protruding at intervals along the inserts 41 to achieve a locking connection between the housing 4 and the lower housing 3. By rotating the housing 4, the inserts 41 pass through the lower housing 3, and the locking blocks 42 abut against the lower housing 3, thus enabling the installation and removal of the housing 4 and the lower housing 3. The structure is simple and the operation is convenient.

[0038] Reference Figure 4 In some embodiments, the mounting housing also includes a baffle 5. The connecting plate 1 is located at one rotating end of the housing 4 and is spaced apart from the upper side of the housing 4. The baffle 5 is rotatably connected to one end of the housing 4 and rotatably connected to the lower housing 3. By rotating the baffle 5, multiple connectors 2 can be shielded to prevent dust from entering the lower housing 3 as much as possible, so as to protect the components in the lower housing 3.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
