Technical Field

[0001] The utility model belongs to the field of industrial technology and relates to an electric connector, which is a universal electric connector. Background Art

[0002] With the development of industrial technology, the complexity of the internal structure of electronic devices is increasing. Various components need to conduct various electrical signals through circuits, and electrical connectors are devices used to connect or link different cables or wire lines. A cable that transmits electrical signals can be integrated with multiple small wires. To connect the wires that transmit electrical signals, it is necessary to ensure that each small wire is connected one by one. However, the existing electrical connector structure is too simple. Therefore, when it is necessary to connect through an electrical connector, it is difficult to quickly locate the position of each small wire. Each small wire needs to be connected carefully to the corresponding small wires. The operator needs to carefully distinguish the small wires and connect them one by one, which takes a lot of time, is very inconvenient to install and use, reduces the installation efficiency and is prone to errors.

[0003] In the utility model patent with announcement number CN217589587 U, which was submitted by Chengdu Sanjiu Precision Technology Co., Ltd. on October 21, 2021 and published on October 14, 2022, an electrical connector for aviation aircraft is disclosed, including a socket insulating shell and a plug-in sleeve, the socket insulating shell is located on the left side of the plug-in sleeve; a threaded sleeve is fixedly connected to the outer side of the socket insulating shell, a threaded plug-in sleeve is sleeved on the outer side of the plug-in sleeve, the inner side of the threaded sleeve and the outer side of the threaded plug-in sleeve are both provided with threads, the threaded plug-in sleeve is inserted into the threaded sleeve and threadedly connected to the threaded sleeve; a slot is provided on the right side of the socket insulating shell, a positioning slot is provided at the upper end of the slot, a positioning plug is fixedly connected to the upper side of the left end of the plug-in sleeve, the plug-in sleeve is inserted into the slot and slidably connected to the inner wall of the slot.

[0004] The technical content disclosed in this document solves the problems raised in the above-mentioned background technology to a certain extent. However, it adopts a positioning plate and a positioning slot to achieve positioning, and still requires the staff to align the positioning plate with the positioning slot for insertion. When inserting the positioning plate in a small area or inside a device with insufficient light, the plate and the slot cannot be directly observed by the naked eye, making it inconvenient to insert the positioning plate.

[0005] Therefore, there is still a need to optimize the structure of the electrical connector in the prior art so as to provide an improved electrical connector, particularly a universal electrical connector, which can overcome one or more disadvantages in the prior art. Utility Model Content

[0013] According to the above aspects of the utility model, preferably, the elastic tube can be made of silicone or rubber. In this way, the elastic tube can be allowed to deform elastically in the radial direction so that the plug can be inserted into the elastic tube, and after being installed in place, the elastic tube has an elastic restoring force to allow the limit ring to be locked in the limit ring groove.

In this way, the female connector wraps the male connector, the second receiving part wraps the inner plug, and the pin in the inner plug is inserted into the socket, forming a multiple nested matching connection structure, further enhancing the reliability of the connection.

[0018] According to the above aspects of the utility model, preferably, a guide rail is provided on the outer surface of the inner plug, and a guide groove is provided on the inner surface of the slider, and the guide rail cooperates with the guide groove to allow the slider to slide in the length direction relative to the inner plug, while preventing the slider from moving in the circumferential direction relative to the inner plug. In this way, it can further help improve the connection efficiency and facilitate the guiding cooperation of the plug block.

[0019] According to the above aspects of the utility model, in order to better facilitate the connection operation of the operator and further improve the connection efficiency, preferably, the first accommodating portion may include a cylindrical cavity, and the slider and the plug block may have a cylindrical outer surface to allow the plug block to rotate in the circumferential direction within the first accommodating portion.

[0020] In summary, the beneficial technical effects of the electrical connector according to the present invention may include but are not limited to the following aspects:

[0021] 1) The electrical connector according to the utility model can automatically adjust the angle, align, facilitate blind insertion, and lock.

[0022] In a preferred embodiment, the inclined cylindrical slider is hollow and can slide. It is installed on the inner plug. The slider is initially located at the rightmost end of the plug. The inclined surface of the slider corresponds to the inclined surface of the plug block, which has the functions of guiding and automatic alignment. It cooperates with the plug block to play the role of blind insertion, and the connection is relatively firm. In addition, it is also relatively convenient to loosen under the action of the biasing member. The elastic ring can play the role of a spring, pushing the rigid ring to move outward, and at the same time, the rigid ring sleeved outside the elastic tube can prevent the limit ring from falling out when it is not pushed by humans. In this way, the connection efficiency of the electrical connector can be improved, and the connection stability of the electrical connector can be enhanced.

[0023] 2) The electrical connector according to the utility model has strong sealing performance, explosion-proof and dust-proof.

[0067] It should be understood that, unless explicitly stated otherwise, the present invention may adopt various alternative orientations and step sequences. It should also be understood that the specific devices shown in the drawings and described in the specification are merely exemplary embodiments of the utility model concepts disclosed and defined herein. Therefore, unless otherwise explicitly stated, the specific orientations, directions or other physical features involved in the various embodiments disclosed should not be considered as limitations.

[0068] Figure 1 1 shows a schematic cross-sectional view of an electrical connector 100 according to a non-limiting embodiment of the present invention, wherein the electrical connector 100 is in a connected state; and Figure 2 A schematic cross-sectional view of an electrical connector 100 according to a non-limiting embodiment of the present invention is shown, wherein the electrical connector 100 is in an unconnected state.

[0069] As shown and as a non-limiting example, the electrical connector 100 can be used to electrically connect the first cable 200 to the second cable 300 in the length direction A. The first cable 200 and the second cable 300 can be various types of wires or wire harnesses, such as electric wires or wires, including various wire types and thicknesses.

[0070] The first cable 200 and the second cable 300 may each include a plurality of small or thin conductors or strands, and preferably, the first cable 200 and the second cable 300 may have the same number of small or thin conductors or strands. Of course, in an alternative embodiment, the first cable 200 and the second cable 300 may also be cables having only one conductor.

[0071] like Figure 1 and 2 As shown, the electrical connector 100 may mainly include a female connector 10 and a male connector 20, the female connector 10 may be connected to a first cable 200, and the male connector 20 may be connected to a second cable 300. In an alternative embodiment, the female connector 10 may be connected to the second cable 300, and the male connector 20 may be connected to the first cable 200.

[0072] Figure 3 A schematic cross-sectional view of a female connector 10 of an electrical connector 100 according to a non-limiting embodiment of the present invention is shown; and Figure 4 yes Figure 3 A schematic side view of the female connector 100 is shown.

[0073] As shown in the figure, the female connector 10 may mainly include a mounting seat 11 , an inner plug 12 and a slider 13 .

[0074] The mounting seat 11 may be used to fix or hold the first cable 200 . For example, the mounting seat 11 may be made of silicone and may be overmolded onto the end of the first cable 200 .

[0075] The mounting base 11 may include a base 110 and an elastic cylinder 111 extending from the base. For example, the elastic cylinder 111 may extend from the base 110 in a direction away from the first cable 200 and form a first receiving portion 11A, which may include a substantially cylindrical cavity.

[0076] In addition, the base 110 and the elastic tube 111 may both have a cylindrical outer surface shape, and the outer diameter of the elastic tube 111 may be smaller than the outer diameter of the base 110, so that a shoulder 110A may be formed between the base 110 and the elastic tube 111. As an example, the elastic tube 111 may be made of a non-metallic insulating material, such as silicone or rubber.

[0077] The free end of the elastic tube 111 opposite to the base 110 may be provided with a limiting ring 111A protruding radially inward. Figure 3 As shown in FIG. 1 , the stop ring 111A is disposed at the distal end of the free end of the elastic tube 111 and is circumferentially disposed on the inner circumferential surface of the elastic tube 111 .

[0078] The stop ring 111A may be integrally formed with the elastic tube 111, or may be separately formed and then fixed to the elastic tube 111 by welding, gluing, etc. As an example, the stop ring 111A may have a substantially semicircular cross section.

[0079] In addition, if Figure 3 As shown, the mounting seat 11 may further include a rigid ring 112 and an elastic ring 113 connected between the rigid ring 112 and the base 110. The rigid ring 112 may be circumferentially arranged outside the elastic cylinder 111.

[0080] For example, the elastic ring 113 may be connected between the shoulder 110A and the rigid ring 112. The elastic ring 113 can be elastically deformed in the length direction A, so that the rigid ring 112 can move along the length direction A, for example, away from or toward the base 110, that is, toward or away from the free end of the elastic ring 113. The elastic ring 113 may be configured to bias the rigid ring 112 away from the base 110, that is, toward the free end of the elastic tube 111.

[0081] Thus, in the absence of external force or in the connected state, the rigid ring 112 at least partially presses against the free end of the elastic cylinder 111. As an example, the rigid ring 112 may be made of metal or a metal alloy, such as a titanium alloy.

[0082] When in use, the operator can push the rigid ring 112 to the right so that the rigid ring 112 is sleeved outside the position of the limiting ring 111A to prevent the limiting ring 111A from bulging outward, thereby restricting the limiting ring 111A and preventing the limiting ring 111A from falling out of the limiting ring groove 211, that is, preventing the plug block 21 from falling out, thereby achieving a highly stable connection with good stability.

[0083] The inner plug 12 may be disposed in the first accommodation portion 11A and have a first electrical connection portion 12A extending in the length direction A. For example, the inner plug 12 may extend from the base 110 and be electrically connected to the first cable 200. For example, the first cable 200 may be plugged, crimped, bolted, snap-fitted, or welded to the inner plug 12.

[0084] As a non-limiting example, the first electrical connection portion 12A may be in the form of a socket, for example Figure 4As schematically shown in FIG. 1 , six sockets are provided on the end of the inner plug 12. In alternative embodiments, the first electrical connection portion 12A may also be in the form of a pin or a plug, and may have a different number and / or arrangement.

[0085] like Figure 3 As shown, the slider 13 can slide along the inner plug 12 in the length direction A and has a first form-fitting portion 13A. As a non-limiting example, the slider 13 can have a generally cylindrical shape, and preferably, the first form-fitting portion 13A can be formed in the shape of an inclined surface. In this way, the slider 13 can be in the form of an inclined cylinder having an inclined surface at its end.

[0086] Figure 5 A schematic perspective view of an inner plug 12 and a slider 13 of a female connector 100 according to a non-limiting embodiment of the present invention is shown; and Figure 6 A schematic perspective view of a slider 13 of a female connector 100 according to a non-limiting embodiment of the present invention is shown.

[0087] As shown in the figure, the slider 13 can slide along the inner plug 12 in the length direction A. To this end, a guide rail 12B may be provided on the outer surface of the inner plug 12, and the guide rail 12B may extend in the length direction A. Similarly, a guide groove 13B is provided on the inner surface of the slider 13, and the guide groove 13B penetrates the inner surface of the slider 13 and may also extend in the length direction A.

[0088] In this way, the guide rail 12B cooperates with the guide groove 13B to allow the slider 13 to slide in the length direction A relative to the inner plug 12 , while preventing the slider 13 from moving in the circumferential direction C relative to the inner plug 12 .

[0089] In addition, if Figure 1-3 As shown in FIG. 1 , the female connector 10 may further include a biasing member 14, which may be in the form of a spring (e.g., a linear spring, a helical spring, etc.), and may be sleeved on the inner plug 12. The biasing member 14 may be disposed between the base 110 and the slider 13, and bias the slider 13 toward the free end of the inner plug 12. For example, as the slider 13 moves toward the base 110, the linear spring may be compressed, thereby forcing the slider 13 to move away from the base 110, i.e., toward the free end of the inner plug 12.

[0090] Figure 7 A schematic cross-sectional view of a male connector 20 of an electrical connector 100 according to a non-limiting embodiment of the present invention is shown; and Figure 8 yes Figure 7 A schematic side view of a male connector 20 is shown.

[0091] As shown in the drawings, the male connector 20 may mainly include an insert block 21. The insert block 21 may have a cylindrical outer surface to allow the insert block 21 to rotate in the circumferential direction C within the first accommodation portion 11A.

[0092] The plug block 21 may include a base 210, which may be used to fix or hold the second cable 300. The plug block 21 may be made of a composite material, such as PC material.

[0093] The insert block 21 can be inserted into the first receptacle 11A and has a second receptacle 21A which can receive the inner connector 12 .

[0094] As shown in the figure, the plug block 21 may have a second shape-matching portion 21B, which matches the first shape-matching portion 13A. For example, the end of the plug block 21 may be a slope, which may match the slope of the slider 13. In this way, the second shape-matching portion 21B is formed into the shape of a matching slope that matches the first shape-matching portion 13A.

[0095] In addition, if Figure 7 and 8 As shown in , the plug block 21 may have a second electrical connection portion 21C, and the second electrical connection portion 21C may be shaped as a pin that matches with the socket.

[0096] In an alternative embodiment, as described above, when the first electrical connection portion 12A is in the form of a pin or plug, the second electrical connection portion 21C may be in the form of a jack or socket. In addition, the number and arrangement of the second electrical connection portions 21C may be the same or similar to the first electrical connection portion 12A to allow a mating connection therebetween.

[0097] In this way, as the male connector 20 moves toward the female connector 10, the plug block 21 will move toward the slider 13 accordingly, and after contacting the inclined surface of the slider 13, it will tend to match the inclined surface, thereby guiding the plug block 21 to move to the desired position in the circumferential direction to allow the second electrical connection portion 21C to align and match with the first electrical connection portion 12A, thereby achieving electrical connection.

[0098] In addition, if Figure 1 , 2 As shown in FIGS. 7 and 7 , the insert block 21 may be provided with a limiting ring groove 211 , and when the female connector 10 and the male connector 20 are in a mating connection state, the limiting ring 111A may be locked into the limiting ring groove 211 .

[0099] The following describes an example use process of the electrical connector 100 according to the present invention. When in use, an operator can hold the first cable 200 (i.e. Figure 1-2The left wire in the figure) or the second cable 300 (i.e. Figure 1-2 When the insert block 21 is inserted into the elastic tube 111, the inclined cylindrical end surface of the slider 13 in the elastic tube 111 corresponds to the insert block 21.

[0100] Since the plug block 21 and the second cable 300 (ie Figure 1-2 The right side wire in the inner plug 12 is fixedly connected together, and under the guidance of the inclined surface of the inclined cylindrical end surface of the slider 13, it has the function of guiding automatic alignment, and the inclined surface of the plug block 21 will eventually be in close contact with the inclined surface of the inclined cylindrical end surface. At this time, the first electrical connection part (such as the jack) of the inner plug 12 and the second electrical connection part 21C (such as the plug or the conductor rod) on the plug block 21 are exactly in the corresponding position.

[0101] Then, the insert block 21 is pushed inward (ie, toward the base 110 ), so that the inclined cylinder presses the biasing member 14 , such as a linear spring, to move leftward. Then, the stop ring 111A falls into the stop ring groove 211 .

[0102] During insertion, the operator can hold the mounting base 11 with the left palm, and use the fingers to pull the rigid ring 112 to the left, so that the rigid ring 112 squeezes the elastic ring 113 to move to the left, and the limiting ring 111A can expand outward into the limiting ring groove 211. When the insertion is completed, the operator can let go, and the rigid ring 112 is pushed by the elastic restoring force of the elastic ring 113 to be sleeved on the outside of the limiting ring 111A, preventing the limiting ring 111A from falling out of the limiting ring groove 211, thereby achieving a stable connection.

[0103] The electrical connector 100 according to the utility model can solve the technical problem of the prior art that manual observation is required during installation, which makes installation inconvenient. The connection achieved by the electrical connector 100 is relatively firm, and under the action of the biasing member 14, it is also relatively easy to loosen, thereby making it more convenient to perform repeated plugging and unplugging operations.

[0104] As used herein, the terms "length direction", "circumferential direction" indicating position or orientation, and the terms "first", "second", etc. used to indicate order are only for the purpose of enabling those skilled in the art to better understand the concept of the present invention shown in the form of a preferred embodiment, and are not used to limit the present invention. Unless otherwise specified, all orders, positions or orientations are only used for the purpose of distinguishing one element / component / structure from another element / component / structure, and unless otherwise specified, do not represent any specific order, order of operation, direction or orientation. For example, in an alternative embodiment, the "first cable" may be the "second cable", and the "first form-fitting portion" may alternatively refer to the "second form-fitting portion".

[0105] In summary, the electrical connector 100 according to the embodiment of the present utility model overcomes the shortcomings of the prior art and achieves the intended purpose of the utility model.

[0106] Although the electrical connector of the utility model is described above in combination with the preferred embodiments, those skilled in the art should recognize that the above examples are only for illustration and cannot be used as a limitation of the utility model. Therefore, various modifications and variations can be made to the utility model within the spirit of the claims, and these modifications and variations will fall within the scope required by the claims of the utility model.
