DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the application is used, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0039] Furthermore, the terms "horizontal", "vertical", and the like are used as terms of convenience and are not intended to limit the components oriented absolutely horizontally or vertically, but can be slightly inclined. For example, "horizontal" merely means that the direction thereof is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0040] In the description of the embodiments of the present application, it should also be noted that the terms "set", "mount", "communicate", "connect" should be understood broadly unless otherwise explicitly specified and limited, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the internal communication of two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0041] According to the present application, a simple-to-assemble and reliable electromagnetic valve connector is provided, as shown in Figures 1 to 17 The simple-to-assemble and reliable electromagnetic valve connector is used for electrical connection between an electromagnetic valve and a controller or the like, and comprises an insulator 1 and a contact assembly.

[0042] In the following description, reference will be made to Figures 1 to 17 The detailed structure of the insulator 1 and the contact assembly of the simple-to-assemble and reliable electromagnetic valve connector will be described in detail.

[0043] As shown in Figures 1 to 5 and Figure 8 In the embodiment, the simple-to-assemble and reliable electromagnetic valve connector can comprise a plug 5, a socket 6, and a cable joint 9, a cable wire or a lead wire or the like cable is threaded through the cable joint 9 and connected with the contact assembly inside the plug 5, the socket 6 is provided with a pin 601, and the socket 6 and the plug 5 are butted through the pin 601 and the contact assembly.

[0044] Further, as shown in Figures 1 to 5 In the embodiment, the plug 5 can comprise a shell 7 and the insulator 1 arranged inside the shell 7, and the contact assembly is mounted on the insulator 1.

[0045] Specifically, as shown in Figure 5 , Figures 11 to 17 In the embodiment, the contact assembly can comprise a wire pressing frame 2 and a jack 3, the wire pressing frame 2 is used for the insertion and fastening of the terminal of the cable wire or the lead wire, and the jack 3 is used for butting the pin 601.

[0046] As shown in Figures 9 to 13As shown, the insulator 1 has a first mounting portion 101 and a second mounting portion 102 that are interconnected. The first mounting portion 101 and the second mounting portion 102 are used for mounting the wire clamping frame 2 and the socket 3, respectively. The first mounting portion 101 has a first slot 103, and the second mounting portion 102 has a second slot 104. In this embodiment, the wire clamping frame 2 and the socket 3 are snapped onto the insulator 1 through the first slot 103 and the second slot 104. Therefore, the heat fusion process in the original structure is no longer required, simplifying the installation steps. At the same time, the snap-fit ​​connection makes the assembled insulator 1, wire clamping frame 2, and socket 3 a single unit, resulting in higher connection strength. Therefore, when installing the terminals of cables or wires, the wire clamping screw 11 will not twist due to torque during the tightening process.

[0047] like Figure 11 As shown, in this embodiment, the wire clamping frame 2 is mounted on the first mounting portion 101 of the insulator 1 along the first direction S1, and can be snapped into the first slot 103 to achieve fixed installation of the wire clamping frame 2 and the insulator 1. The first direction S1 can be understood as the direction in which the wire clamping frame 2 faces the first mounting portion 101 of the insulator 1. Since the insulator 1 can have multiple first mounting portions 101 in this embodiment, multiple wire clamping frames 2 can be installed accordingly. Therefore, the first direction S1 of each wire clamping frame 2 is different, but it is always the direction in which each wire clamping frame 2 faces the first mounting portion 101 of the insulator 1. Figure 12 As shown, the socket 3 is installed on the second mounting part 102 of the insulator 1 along the second direction S2 and is snapped into the second slot 104. The second direction S2 is the direction in which the socket 3 faces the insulator 1. Since both the wire clamp 2 and the socket 3 are installed on the insulator 1 by snap-fit, the heat-fusion step in the original assembly process can be omitted while ensuring the connection strength. It is not necessary to fix the contact components to the insulator 1 by heat fusion. The wire clamp 2 and the socket 3 can also be assembled separately, simplifying the overall assembly steps.

[0048] like Figure 14 and Figure 15 As shown, in this embodiment, the wire clamping frame 2 has a receiving portion 201 in the middle for receiving the terminal of a cable or wire. Figure 16 As shown, in this embodiment, the socket 3 may include a connecting portion and a contact portion 301. An insulator 1 passes through the connecting portion, which includes two facing connecting pieces 302. When the socket 6 and plug 5 are mated, the pin 601 can mate with the connecting pieces 302 to achieve electrical connection. The two facing connecting pieces 302 increase the contact area with the pin 601 and have a specially designed bending shape, which enhances the strength of the socket 3 and makes it less prone to deformation. Figure 17As shown, in the embodiment, the contact part 301 is bent by the end of the jack 3 towards the position where the crimping frame 2 is located, so that the end of the contact part 301 extends into the accommodating part 201 and abuts against the crimping frame 2. In this way, the contact assembly of the solenoid valve connector is in the form of direct abutment, so that the wire terminal can directly contact the crimping frame 2 and the jack 3 directly, and the wire terminal does not need to contact the crimping frame 2 and the jack 3 through the crimping frame 2, which simplifies the connection and reduces the contact resistance. In addition, through the direct abutment form of the crimping frame 2 and the jack 3, the step of riveting the two in the original assembly process is omitted, avoiding the complexity of the riveting process and simplifying the assembly steps.

[0049] The assembly simple and reliable solenoid valve connector can realize reliable electrical connection between the solenoid valve and the controller and other devices through the cooperation of the insulator 1 and the contact assembly; through the direct contact of the crimping frame 2 and the jack 3, the contact part 301 of the jack 3 can be arranged in the accommodating part 201 of the crimping frame 2 and abut against the crimping frame 2, thereby omitting the step of riveting the crimping frame 2 and the jack 3 in the original assembly process, avoiding the complexity of the riveting process, and simplifying the assembly steps; in addition, due to the direct contact connection form of the crimping frame 2 and the jack 3, the wire terminal mounted on the crimping frame 2 can contact the crimping frame 2 and the jack 3 at the same time, thereby solving the problem of large contact resistance caused by the need for relay contact in the prior art, improving the overall mechanical life, and firmly assembling the parts; through the separate clamping of the crimping frame 2 and the jack 3 on the insulator 1, the hot melting step in the original assembly process is omitted on the basis of ensuring the installation and connection strength, so that the crimping frame 2 and the jack 3 can be integrated with the insulator 1, and the problem of torsion during subsequent screwing of the crimping top screw 11 is also avoided; through the connection sheet 302 arranged opposite to each other on the jack 3, the contact area of the pin 601 and the jack 3 can be increased, thereby solving the problems of poor connectivity and conductivity, and at the same time, through the special shape design of the jack 3, the structural strength of the jack 3 can be increased, and the risk of deformation of the jack 3 can be reduced. The assembly simple and reliable solenoid valve connector has novel structure and simple assembly and connection process, the contact piece structure used is novel and the number is small, and the assembly can be completed by using a universal tool; since each part is molded by a mold, the cost of the parts is low, and batch production is suitable; the assembly simple and reliable solenoid valve connector is convenient to assemble, has high connection reliability, and can be stably connected under various working conditions.

[0055] ​​​​Preferably, such as Figure 16 and Figure 17 As shown, in this embodiment, the middle portions of the two facing connecting pieces 302 are bent towards the position between them to facilitate better contact with the pin 601; the two facing inner walls of the second mounting portion 102 are provided with second slots 104, and the main body 303 includes two inclined second locking blocks 304, the distance between the two second locking blocks 304 gradually decreasing along the second direction S2.

This simple-to-assemble and reliable solenoid valve connector places the manual end 802 of the through-screw 8 outside the housing 7, allowing operators to manually adjust the through-screw 8 and tighten the plug 5 and socket 6 without the need for tools. Existing solenoid valve connections require tools to tighten screws because the screws are located inside the housing. In space-constrained conditions, this makes it impossible to tighten the screws, necessitating disassembly and repositioning of the connector. However, with the manual end 802 of the through-screw 8, operators are not limited by the working environment and can adjust the connection strength of the plug 5 and socket 6 according to the usage.
