Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to an electrical connector plug and an electrical connector. Background Art

[0002] As a key component for signal transmission between electrical devices, electrical connectors' fundamental function is to achieve reliable signal transmission by forming a closed circuit through the connection of pins and sockets. Currently, connectors across various industries generally adopt a one-in, one-out transmission mode, meaning each contact connects only a single wire, primarily through processes such as crimping and welding.

[0003] However, with the continuous expansion of application scenarios, some special working conditions have put forward functional requirements for connectors with one input and multiple outputs. Taking the crimping process as an example, existing solutions usually use a single crimping barrel to crimp multiple wires at the same time. However, it should be pointed out that this operation method has certain technical defects: First, the size specifications of the crimping barrel and the wire specifications are strictly constrained by relevant standards. The method of crimping multiple wires with a single crimping barrel at the same time does not comply with the current technical specifications and poses a potential safety hazard. Secondly, after the wire crimping process is operated, once the one-in-multiple-out mode is adopted, it cannot be changed. If it is necessary to restore to the one-in-one-out mode, the entire contact must be replaced, which not only increases maintenance costs, but also affects the reliability of the system. Summary of the Invention

Detailed Description of the Invention

[0027] The following detailed description is provided to assist the reader in obtaining a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the disclosure of the present application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, changes that will be apparent after understanding the disclosure of the present application may be made, except for operations that must occur in a specific order. Additionally, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0028] The features described herein can be implemented in various forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0029] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0030] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0031] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, a first component, element, region, layer, or part as referred to in the examples described herein may also be referred to as a second component, element, region, layer, or part without departing from the teachings of the examples.

[0032] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0033] The terms used herein are for describing various examples only and are not intended to limit the examples. Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprise", "include" and "have" enumerate the stated features, quantities, operations, components, elements and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0034] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Accordingly, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0035] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible, as will be apparent after understanding the disclosure of the present application.

[0036] As Figures 1 to 8 shown, according to a first aspect of the present invention, there is provided an electrical connector plug, which includes a housing assembly 1, an insulator assembly 2, an adapter plug 3, and a terminal 4.

[0037] In the following description, reference will be made to Figures 1 to 8 specifically describe the specific structures of the above components of the electrical connector plug and the connection relationships of the above components.

[0038] As Figures 1 to 8 shown, in the embodiment, the insulator assembly 2 can be installed inside the housing assembly 1, and the insulator assembly 2 is used to perform an insulating function. A first end of the housing assembly 1 (which can be the left end as Figure 1 shown) can be provided with a first opening 101 for docking with a socket of the electrical connector. A second end of the housing assembly 1 (which can be the Figure 1The right end shown can be provided with a second opening 102 for a wire (not shown) to pass through. A plurality of adapter plugs 3 can be installed in the insulator assembly 2. The adapter plug 3 can include a docking end socket 31 and a plurality of outgoing line end sockets 32. Among them, the docking end socket 31 can be plugged and mated with the socket. Specifically, the docking end socket 31 can be plugged and mated with the pin of the socket. A plurality of wiring terminals 4 can also be installed in the insulator assembly 2. The wiring terminal 4 can be plugged and mated with the outgoing line end socket 32 of the adapter plug 3, and the wire can be connected to the wiring terminal 4. With such a setting, the pin of the socket can be electrically connected to a plurality of wires simultaneously through the adapter plug 3 and the wiring terminal 4 to achieve a one-in-multiple-out transmission mode. By adjusting the number of wiring terminals 4, the socket can also be electrically connected to only one wire. In addition, covering the adapter plug 3 and the wiring terminal 4 in the insulator can greatly improve the safety during use, so as to effectively improve the reliability of the electrical connector.

[0039] Preferably, as Figures 1 to 4 and Figure 8 shown, in the embodiment, the insulator assembly 2 can be a columnar structure, which can support and insulate the internal contact bodies (i.e., the adapter plug 3 and the wiring terminal 4). The insulator assembly 2 can include a first insulator 21 and a second insulator 22. Among them, the first insulator 21 can be arranged at the first end inside the housing assembly 1. A plurality of adapter plugs 3 can be arranged in the first insulator 21 to be close to the first opening 101 of the housing assembly 1. The second insulator 22 can be arranged at the side of the first insulator 21 close to the second end of the housing assembly 1, that is, the second insulator 22 is arranged closer to the second end of the housing assembly 1 than the first insulator 21. A plurality of wiring terminals 4 can be arranged in the second insulator 22 to be close to the second opening 102 of the housing assembly 1. The wiring terminal 4 can partially extend out of the second insulator 22 and extend into the first insulator 21 to be plugged and mated with the adapter plug 3.

[0040] Further, preferably, as Figures 1 to 4 and Figure 8 shown, in the embodiment, the first insulator 21 and the second insulator 22 can both be formed into columnar structures. The first insulator 21 and the second insulator 22 can be coaxially arranged with the first opening 101 and the second opening 102 of the housing assembly 1. The end of the first insulator 21 can be abutted against the end of the second insulator 22, and the diameter of the abutting surface of the first insulator 21 and the second insulator 22 can be the same.

[0041] Preferably, as Figures 1 to 4 and Figure 8As shown, in the embodiment, a plurality of first mounting holes 210 axially penetrating the first insulator 21 may be provided in the first insulator 21. A plurality of adapter plugs 3 may be respectively mounted in the plurality of first mounting holes 210. In this case, the docking end jacks 31 of the adapter plugs 3 may be arranged close to the first end of the housing assembly 1 to dock with the pins of the socket. The lead-out end jacks 32 of the adapter plugs 3 may be arranged close to the second end of the housing assembly 1 to dock with the terminal blocks 4. Each adapter plug 3 may be plugged and mated with no more than the number of lead-out end jacks 32 thereof of the terminal blocks 4 to achieve a one-in-multiple-out or one-in-one-out transmission mode according to different requirements.

[0042] Further, preferably, as Figures 1 to 4 and Figure 8 shown, in the embodiment, a plurality of second mounting holes 220 axially penetrating the second insulator 22 may be provided in the second insulator 22. The terminal blocks 4 may be selectively mounted in the second mounting holes 220. Specifically, the number of the second mounting holes 220 may be equal to the total number of the lead-out end jacks 32 of all the adapter plugs 3, so that the second mounting holes 220 can be arranged in one-to-one correspondence with the positions of the lead-out end jacks 32. The terminal blocks 4 may be selectively mounted in each second mounting hole 220 according to actual requirements, so that the adapter plugs 3 can be electrically connected to any number (not exceeding the number of lead-out end jacks 32) of the terminal blocks 4.

[0043] Further, preferably, as Figures 5 to 8 shown, in the embodiment, the first end of the adapter plug 3 (which may be the left end as shown in Figure 5 the figure) may be a rod-shaped structure. The first end of the adapter plug 3 may be axially provided with a docking end jack 31 to be plugged with the pin of the socket. The second end of the adapter plug 3 (which may be the right end as shown in Figure 5 the figure) may be a block-shaped structure, and two lead-out end jacks 32 may be provided at the second end of the adapter plug 3. In this case, each adapter plug 3 can be electrically connected to at most two terminal blocks 4. More preferably, twelve adapter plugs 3 may be provided in the first insulator 21 to be arranged in a symmetric equilateral triangle and an inverted equilateral triangle. Twenty-four second mounting holes 220 may be correspondingly provided in the second insulator 22.

[0044] In addition, preferably, as Figures 5 to 8As shown, in the embodiment, the adapter plug 3 may be provided with a spring piece 35 at the docking end jack 31, so that the docking end jack 31 can be stably inserted with the pin. The second end of the adapter plug 3 may be provided with a split groove 34 at a position corresponding to the outgoing line end jack 32. The split groove 34 communicates with the outgoing line end jack 32, so that the second end of the adapter plug 3 can be deformed to a certain extent, so as to facilitate the insertion and cooperation of the outgoing line end jack 32 and the terminal 4. The middle part of the adapter plug 3 may be provided with a first claw 33, and the first claw 33 can be deformed to a certain extent in the radial direction of the adapter plug 3. And a first boss 211 protruding radially may be provided in the first mounting hole 210 of the first insulator 21. The first claw 33 can be clamped with the first boss 211. Specifically, the adapter plug 3 may be inserted from the end of the first insulator 21 for docking with the second insulator 22. When the first claw 33 passes through the first boss 211, the first claw 33 will be deformed and unfolded, so that the second claw 43 is clamped at the first boss 211 to prevent the adapter plug 3 from moving axially in the first insulator 21.

[0045] However, not limited thereto, the structure of the adapter plug 3 realizing the insertion and cooperation with other components through the spring piece 35 and the split groove 34 is only a preferred case in the embodiment. In the actual use process, as long as the stable connection between the adapter plug 3 and other components can be ensured, other cooperation structures can also be adopted, such as crown springs or torsion springs, etc.

[0046] More preferably, as Figures 5 to 8 shown, in the embodiment, the first end of the terminal 4 (which may be the Figure 8 left end shown) may be formed with a rod-shaped insertion portion 41. The rod-shaped insertion portion 41 may extend out of the second insulator 22 and be inserted and cooperated with the docking end jack 31 of the adapter plug 3 to achieve electrical connection. The second end of the terminal 4 (which may be the Figure 8 right end shown) may be provided with a wiring hole 42. The wiring hole 42 is arranged along the axial direction of the terminal 4, and the wire may be inserted into the wiring hole 42 to achieve electrical connection between the wire and the terminal 4. The middle part of the terminal 4 may be provided with a second claw 43, and the second claw 43 can be deformed to a certain extent in the radial direction of the terminal 4. And a second boss 221 protruding radially may be provided in the second mounting hole 220 of the second insulator 22. The second claw 43 can be clamped with the second boss 221. Specifically, the terminal 4 may be inserted from the end of the second insulator 22 away from the first insulator 21. When the second claw 43 passes through the second boss 221, the second claw 43 will be deformed and unfolded, so that the second claw 43 is clamped at the second boss 221 to prevent the terminal 4 from moving axially in the second insulator 22.

[0047] During installation, the plurality of connection terminals 4 can be installed one by one into the second insulator 22, so that each connection terminal 4 is connected to the corresponding adapter 3. Alternatively, the plurality of connection terminals 4 can be installed together into the second insulator 22, and then the second insulator 22 is connected to the first insulator 21, so that the plurality of connection terminals 4 are connected to the plurality of adapters 3.

[0048] In this embodiment, the insulator assembly 2 differs from conventional insulator structures in that both the adapter 3 and the terminal block 4 are secured within the insulator assembly 2 by means of their own claw structures, rather than being clamped between the first insulator 21 and the second insulator 22. This arrangement eliminates the need for the adapter 3 to contact the second insulator 22, meaning that the gap between the first insulator 21 and the second insulator 22 will not affect the adapter 3. This improves the insulation between the adapter 3 and the electrical performance of the electrical connector.

[0049] Preferably, Figure 1 As shown, in an embodiment, the housing assembly 1 may include a housing 11, a tail nut 12, and a connecting nut assembly 13. The housing 11 may be sleeved around the outer periphery of the insulator assembly 2. The housing 11 is used to support and protect the insulator assembly 2 therein. The tail nut 12 may be threadedly connected to the end of the housing 11. Specifically, the end of the housing 11 near the second opening 102 may be provided with external threads. The tail nut 12 may be partially sleeved around the end of the housing 11, and internal threads may be provided at portions of the inner surface of the tail nut 12 to achieve a threaded connection. The second opening 102 is formed at the end of the tail nut 12 not connected to the housing 11. The connecting nut assembly 13 may be sleeved on the exterior of the housing 11. The first opening 101 may be formed at the end of the connecting nut assembly 13 away from the tail nut 12. The connecting nut assembly 13 may be clamped and fixed between the housing 11 and the tail nut 12. The connecting nut assembly 13 is used to connect to the housing of the socket and be locked.

[0050] Further, preferably, Figure 1 and Figure 2 As shown, in an embodiment, the first insulator 21 may be formed with a first annular protrusion 212 protruding radially at the end that interfaces with the second insulator 22. The second insulator 22 may be formed with a second annular protrusion 222 protruding radially at the end that interfaces with the first insulator 21. A ridge may be formed on the inner side of the housing 11, and the end of the first annular protrusion 212 may be engaged with the ridge on the inner surface of the housing 11. The ridge is located on the side of the first annular protrusion 212 away from the second insulator 22, thereby axially positioning the first insulator 21.

[0051] In addition, preferably, Figure 1 As shown, an annular top sleeve 14 may be sandwiched between the tail nut 12 and the end of the second annular protrusion 222. The top sleeve 14 may be sleeved around the outer circumference of the second insulator 22 and may be movable axially along the second insulator 22. When the operator tightens the tail nut 12, the tail nut 12 pushes the top sleeve 14, causing the top sleeve 14 to press against the second insulator 22, thereby causing the second insulator 22 to abut against the first insulator 21, thereby axially positioning the insulator assembly 2.

[0052] More preferably, Figure 1 As shown, in an embodiment, the inner wall of the connecting nut assembly 13 may be formed with a radially protruding annular portion 130. The outer wall of the housing 11 may be formed with an annular protrusion 110. When the operator tightens the tail nut 12, the annular portion 130 will be clamped between the protrusion 110 and the end of the tail nut 12, thereby positioning the connecting nut assembly 13.

[0053] Furthermore, according to a second aspect of the present invention, there is provided an electrical connector, comprising the electrical connector plug as described above.

[0054] During use, the mating end socket 31 of the adapter plug 3 is electrically connected to the socket's pins, and the multiple outlet end sockets 32 of the adapter plug 3 are electrically connected to the wiring terminals 4, thereby achieving a one-in, multiple-out transmission mode. When some wiring terminals 4 are removed, each adapter plug 3 can be electrically connected to only one wiring terminal 4, restoring the one-in, one-out transmission mode of the electrical connector plug. The adapter plug 3 and wiring terminals 4 can be removed using a dedicated extraction tool, which provides high maintainability and improves the reliability of the electrical connector.

[0055] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
