[0002] Electrical connectors are required for electrical connections. Existing electrical connectors have plugs and male and female plugs, and they are tightened and locked by thread matching, which makes the connection and installation cumbersome and inefficient. This inhibits the production efficiency of wire connectors and makes it inconvenient for workers to disassemble the connectors.

[0003] Therefore, it is necessary to provide a new electrical pluggable connector to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an electrical pluggable connector.

[0005] The electrical pluggable connector provided by this utility model includes:

[0006] The device includes an insertion housing and an insertion chip fixedly fitted inside the end of the insertion housing, wherein the end of the insertion housing is fixedly fitted with an annular tube for protecting the insertion chip.

[0007] The connection housing includes an electrode post fixedly fitted inside the end of the connection housing, and the end of the connection housing is fixedly fitted with an annular sleeve for protecting the inserted chip.

[0008] The feature is that the annular insertion tube is adapted to the annular sleeve, and the insertion housing has multiple installation cavities, and each installation cavity is provided with an insertion housing snap-fit ​​connection housing driving snap-fit ​​component.

[0009] The annular cannula has multiple annularly distributed oblique arc-shaped slots, and the inlet of the oblique arc-shaped slots is flush with the end of the annular cannula. The inner wall of the annular sleeve has multiple arc-shaped protrusions fixedly fitted, and the arc-shaped protrusions are flush with the end of the annular sleeve.

[0010] Preferably, there are two sets of inclined arc-shaped slots and arc-shaped protrusions that match each other, and the two sets of inclined arc-shaped slots and arc-shaped protrusions are distributed on both sides of the tube body.

[0011] Preferably, the snap-fit ​​assembly includes a connecting plate, which is elastically connected to the inner wall of the mounting cavity by multiple springs, and the connecting plate has pressing posts and snap-fit ​​posts respectively embedded on the plate walls near both ends.

[0012] Preferably, the pressing post penetrates the insertion housing and extends out of the insertion housing, and the snap-fit ​​post penetrates the annular insertion tube and extends out of the annular insertion tube.

[0013] Preferably, a limiting hole is formed on the inner wall of the annular sleeve.

[0014] Preferably, the tail end of the insertion housing is equipped with a wire that is electrically connected to the insertion chip.

[0015] Preferably, the connecting housing is fixedly fitted onto the plate surface of the electrical equipment, and the electrode post inside the end of the connecting housing is electrically connected to the circuit inside the electrical equipment.

[0016] Compared with related technologies, the electrical pluggable connector provided by this utility model has the following advantages:

[0017] This utility model provides an electrical pluggable connector. The annular insert has an angled arc-shaped groove corresponding to an arc-shaped protrusion in the annular sleeve. The annular insert on the insertion housing is then inserted into the annular sleeve in the connecting housing. During insertion, the angled arc-shaped groove slides inward along the arc-shaped protrusion, causing the annular insert to rotate along the sliding trajectory of the groove until it is fully inserted into the annular sleeve. This achieves both energization of the insertion housing and the connecting housing and locks the annular insert into the annular sleeve. This prevents the annular insert from easily slipping off the annular sleeve when the wires on the insertion housing are subjected to external tension. The locking component further improves the stability of the connection between the insertion housing and the connecting housing, reducing the problem of loosening due to connector rotation.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 This utility model provides an electrical pluggable connector, which includes: a plug-in housing 1 and a connecting housing 1'. A plug-in chip 2 is fixedly embedded in the end of the plug-in housing 1, and an annular sleeve 3 for protecting the plug-in chip 2 is fixedly sleeved on the end of the plug-in housing 1. An electrode post 2' is fixedly embedded in the end of the connecting housing 1', and an annular sleeve 3' for protecting the plug-in chip 2 is fixedly sleeved on the end of the connecting housing 1'. A wire electrically connected to the plug-in chip 2 is installed at the tail end of the plug-in housing 1. The connecting housing 1' is fixedly embedded on the board surface of an electrical device, and the electrode post 2' in the end of the connecting housing 1' is electrically connected to the circuit in the electrical device.

[0026] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 and Figure 4 The annular insertion tube 3 has multiple annularly distributed oblique arc-shaped grooves 3a, and the inlet of the oblique arc-shaped grooves 3a is flush with the end of the annular insertion tube 3. The inner wall of the annular sleeve 3' has multiple arc-shaped protrusions 31' fixedly fitted, and the arc-shaped protrusions 31' are flush with the end of the annular sleeve 3'. The oblique arc-shaped grooves 3a and the arc-shaped protrusions 31' are provided in two sets and matched with each other, and the two sets of oblique arc-shaped grooves 3a and arc-shaped protrusions 31' are distributed on both sides of the tube body.

[0027] It should be noted that: the oblique arc-shaped groove 3a inside the annular insertion tube 3 corresponds to the arc-shaped protrusion 31' inside the annular sleeve 3'. Subsequently, the annular insertion tube 3 on the insertion housing 1 is inserted into the annular sleeve 3' inside the connecting housing 1'. At the same time as insertion, the oblique arc-shaped groove 3a slides along the arc-shaped protrusion 31', causing the annular insertion tube 3 to rotate along the sliding trajectory of the oblique arc-shaped groove 3a until the annular insertion tube 3 is completely inserted into the annular sleeve 3'. This realizes the power supply function between the insertion housing 1 and the connecting housing 1', while also locking the annular insertion tube 3 into the annular sleeve 3', so that the wires on the insertion housing 1 will not easily slip out of the annular sleeve 3' after being subjected to external pulling force.

[0028] In the embodiments of this utility model, please refer to Figure 2 and Figure 4 The annular insertion tube 3 is adapted to the annular sleeve 3'. The insertion housing 1 has multiple installation cavities 1a, and each installation cavity 1a is provided with a locking assembly 4 for the insertion housing 1 to engage with the connecting housing 1'. The locking assembly 4 includes a connecting plate 41, which is elastically connected to the inner wall of the installation cavity 1a by multiple springs 42. The connecting plate 41 has a pressing post 43 and a locking post 44 respectively embedded on the plate wall near both ends. The pressing post 43 penetrates the insertion housing 1 and extends out of the insertion housing 1, and the locking post 44 penetrates the annular insertion tube 3 and extends out of the annular insertion tube 3. The inner wall of the annular sleeve 3' has a limiting hole 3a'.

[0029] It should be noted that: before the insertion housing 1 is connected to the connecting housing 1', the two pressing columns 43 are pressed inward, so that the connecting plate 41 is pressed by the spring 42, and then the locking column 44 slides into the annular insertion tube 3. After the insertion housing 1 is connected to the connecting housing 1', the pressing column 43 is released, so that the locking column 44 is inserted into the limiting hole 3a' opened on the inner wall of the annular sleeve 3' under the action of the compression spring 42. This improves the stability of the connection between the insertion housing 1 and the connecting housing 1' and reduces the problem of loose connection caused by the connector rotating.

[0030] In this embodiment, the snap-fit ​​post 44 is located near the tail end of the inclined arc-shaped slot 3a of the annular insert tube 3, while the limiting hole 3a' is located near the tail end of the arc-shaped protrusion 31' of the annular sleeve 3'. Therefore, after the insert housing 1 and the connecting housing 1' are connected, the snap-fit ​​post 44 and the limiting hole 3a' correspond to each other.

[0031] The working principle of the electrical pluggable connector provided by this utility model is as follows:

[0032] Before the insertion housing 1 is connected to the connecting housing 1', the two sides of the pressing column 43 are pressed inward, so that the spring 42 is pressed in the connecting plate 41, and then the locking column 44 slides into the annular insertion tube 3, so that the inclined arc-shaped groove 3a in the annular insertion tube 3 corresponds to the arc-shaped protrusion 31' in the annular sleeve 3'. Then, the annular insertion tube 3 on the insertion housing 1 is inserted into the annular sleeve 3' in the connecting housing 1'. At the same time as insertion, the inclined arc-shaped groove 3a slides inward along the arc-shaped protrusion 31', so that the annular insertion tube 3 rotates along the sliding trajectory of the inclined arc-shaped groove 3a until the annular insertion tube 3 is completely inserted into the annular sleeve 3'. This realizes the power supply function of the insertion housing 1 and the connecting housing 1', and at the same time realizes the locking of the annular insertion tube 3 into the annular sleeve 3', so that the wire on the insertion housing 1 will not easily slip out of the annular sleeve 3' after being subjected to external pulling force.

[0033] After the insertion housing 1 is connected to the connecting housing 1', the pressing post 43 is released, so that the snap-fit ​​post 44 is inserted into the limiting hole 3a' opened on the inner wall of the annular sleeve 3' under the action of the compression spring 42, thereby improving the stability of the connection between the insertion housing 1 and the connecting housing 1' and reducing the problem of loosening of the connection due to the rotation of the connector.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
