Description

Technical Field

[0001] The utility model relates to the technical field of plugs and sockets, in particular to a plug and socket for a motorhome handle. Background Art

[0002] A recreational vehicle (RV), also known as a "home on wheels," combines the functions of both a "house" and a "car," but its nature remains that of a car: a mobile vehicle equipped with the essential amenities of a home. RVs are equipped with various household appliances and onboard batteries, which require external charging. To charge the RV, the RV plug must be connected to an external power source. The conductive components of the socket and plug have a strong engagement force, so the plug is generally firmly inserted into the socket during use, making it difficult to separate the plug and socket after use. Prolonged improper insertion and removal can lead to deformation of the plug and loosening of the socket, compromising the safety of the RV's plugs and sockets.

[0003] China Patent Authorization Announcement Number: CN 219874256 U, Authorization Announcement Date October 20, 2023. The utility model relates to a motorhome socket, aiming to provide a motorhome socket that is convenient for separating the plug from the socket. It includes a handle, one end of the handle is provided with a power cord, and the other end of the handle is provided with a socket core. The socket core is located on one side of the handle, and a finger ring is provided on the other side of the handle corresponding to the handle. The power cord, the socket core and the finger ring are all fixedly connected to the handle and form an integral body. One end of the socket core is located in the handle and electrically connected to the power cord. The other end of the socket core is located outside the handle and is provided with a socket hole. The shape of the socket core and the other end of the handle are both cylindrical. The diameter of the socket core is smaller than the diameter of the other end of the handle. The socket core is located in the center of the handle, and an internal threaded sleeve is provided on the handle. The internal threaded sleeve is rotatably connected to the edge of the other end of the handle, and the socket core is located in the internal threaded sleeve. The shortcomings of this technical solution are: 1. The socket is separated by a finger ring inserted into the handle. The ring-shaped finger ring structure limits the force strength when operated with one finger, and the multi-finger operation causes the force to be squeezed due to the aggregation, resulting in difficulty in operation; 2. The ring-shaped finger ring structure makes it easy for the fingers to slip whether they are in contact with the outside or released from the inside, which makes the picking up unstable, plugging and unplugging difficult, and difficult to align, affecting the stability and safety of plugging and unplugging.

[0004] In summary: the plugs and sockets of RVs have the disadvantages of being difficult to plug and unplug, not being convenient for stable operation and affecting the safety of plugging and unplugging. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art in which plugs and sockets for recreational vehicles are difficult to plug and unplug, inconvenient for stable operation and affect the safety of plugging and unplugging, and provides a recreational vehicle handle plug and socket that is convenient for quick and stable plugging and unplugging, improves operating accuracy and safety and comfort.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A motorhome handle plug socket includes a handle seat, a plug seat and a power cord connected inside the handle seat, a conductive pin connected to the handle seat, the conductive pin being electrically connected to the power cord, a conductive pin hole adapted for the conductive pin being provided on one side of the handle seat, a connecting rod being provided on the other side of the handle seat, one side of the connecting rod being vertically connected to the handle seat, the other end of the connecting rod being vertically connected to a handle rod, and the handle rod being provided with a plurality of finger grooves.

[0008] The RV's power connection structure includes a plug for insertion and a socket into which it is inserted. Both the plug and the socket include a plug socket, a power cord, and conductor pins. The conductive pins are the pins in the plug or the conductive clips in the socket. The pins in the plug connect to the plug socket and are electrically connected to the power cord to form the plug, while the conductive clips in the socket connect to the plug socket and are electrically connected to the power cord to form the socket. Both the plug and the socket use a connecting handle to facilitate plugging and unplugging of the plug or socket. The handle includes a handle socket, a connecting rod, and a handle rod. The handle socket is sleeved on the outside of the plug socket of the plug or socket. The conductive pin holes are located on one side of the handle socket to allow the pins in the plug to extend or the pins in the socket to connect to the conductive clips. A connecting rod is connected to the other side of the handle base, and the connecting rod connects the handle base to the handle rod to improve the integrity of the plug or socket. The handle rod moves the handle base (plug or socket) through the connecting rod to connect the power supply, preventing the plug base from easily falling out of the hand. At the same time, by applying force inward or outward, the plug base can be inserted or removed stably and quickly. The horizontal center axis of the connecting rod is perpendicular to the vertical center axis of the handle base and the handle rod, so that the force is balanced, that is, perpendicular to the horizontal center axis of the conductive pin, so as to achieve fast, stable and safe removal and removal. The surface of the handle rod is provided with a plurality of finger grooves. The finger grooves cooperate with the finger grooves to increase the fit between the handle rod and the fingers to prevent slipping when picking up or inserting and removing. At the same time, the finger grooves cooperate with the rod-shaped structure of the handle rod to increase the force application points to facilitate pressing, adjusting and fixing the alignment angle of the conductive pin. The effect of high connection strength between the structures of the plug and socket is achieved, with integrity, safe insertion and removal operation, high insertion and removal accuracy and efficiency, stable picking and preventing slipping, and improved user comfort is achieved.

[0009] Preferably, the connecting rod has a quadrangular prism shape, with the adjacent side surfaces of the connecting rod connected at arc-shaped points. This streamlined design improves the grip during insertion and removal, preventing the pain associated with applying force at sharp right angles. It also disperses stress more effectively than a right angle, increasing structural strength and preventing breakage. This further enhances user comfort, facilitates force application, and strengthens the connecting rod's structural strength.

[0010] Preferably, the finger groove is located on the inner side of the handle, and the finger groove includes an upper finger groove and a lower finger groove. The upper finger groove is higher than the connecting rod, and the lower finger groove is lower than the connecting rod. The finger groove is located on the inner side of the handle, opposite the handle seat. The finger groove is divided into an upper finger groove and a lower finger groove by the connection between the connecting rod and the handle, so that the upper finger groove and the lower finger groove facilitate the application of force and placement of fingers, thereby achieving the effect of improving the stability of picking up the plug and socket.

[0011] Preferably, the structural shape of the connection between the side of the connecting rod and the side of the handle seat is an arc shape, the structural shape of the connection between the upper side of the connecting rod and the groove surface of the upper finger groove is an arc shape, the structural shape of the connection between the lower side of the connecting rod and the groove surface of the lower finger groove is an arc shape, and the connection between the left and right sides of the connecting rod and the left and right sides of the handle rod are smooth. The connection between the connecting rod and the handle seat in the vertical connection is an arc-shaped connection structure rather than a right angle. At the same time, the upper side of the connecting rod and the upper finger groove, and the lower side of the connecting rod and the lower finger groove are also arc-shaped. The connection between the connecting rod, the handle seat and the handle rod is streamlined to improve the grip when plugging and unplugging the handle, prevent the pain caused by the application of force due to sharp right angles, and at the same time, it disperses stress more than the right angle to improve the structural force strength and prevent the connecting rod from breaking. In addition, the side of the connecting rod and the side of the handle rod are smoothly connected to make the width the same. This further improves the grip comfort, the connection strength and the integrity of the handle structure.

[0012] Preferably, the junctions between the upper and lower end surfaces of the handle and the side surfaces are arc-shaped. One end of the outer side surface of the handle is provided with a first guiding bevel, and the other end of the outer side surface of the handle is provided with a second guiding bevel. Both the first and second guiding bevels are inclined inwardly. The junctions between the upper and lower end surfaces of the handle and the side surfaces are arc-shaped. One end of the outer side surface of the handle is inclined inwardly by the first guiding bevel, and the other end of the outer side surface of the handle is inclined inwardly by the second guiding bevel. This conforms to the groove trend of the upper and lower finger grooves and forms a guiding streamline, which is aesthetically pleasing and prevents obstruction to the palm of the hand. This further improves the grip comfort, aesthetics, and facilitates gripping.

[0013] Preferably, the outer side of the handle is provided with an anti-slip groove. The groove is formed between the outer side of the handle and between the first and second guide slopes to increase friction when gripping, preventing slipping due to palm pressure. It also increases friction during finger-pressing operations, facilitating more stable and rapid insertion of the conductive pins. This improves operational convenience and stability.

[0014] The beneficial effects of the utility model are: the connection strength between the structures of the plug and socket is high and integrated; the operation convenience and stability are improved; the plugging and unplugging operation is safe; the plugging and unplugging accuracy and efficiency are high; the holding is stable to prevent slipping and improve the comfort of use; the grip is comfortable, beautiful and easy to apply force to hold.
