[0002] A connector, also called a coaxial connector, is usually installed on a cable or on an instrument as an element for cable connection or separation.

[0003] In the prior art, in the connection with a cable, in the complex azimuth connection process, the conventional MQ4 connector has high requirements for the connector sequence and topological arrangement, and has the problem of high operation difficulty, resulting in high design costs, which needs to be improved. Summary of the Utility Model

[0004] In view of this, the purpose of this application is to provide an MQ4 connector to significantly reduce the requirements for connector sequence and topological arrangement and effectively reduce the design cost. The specific scheme is as follows:

[0005] An MQ4 connector includes an MQ4 connection head. One end of the MQ4 connection head is provided with a connection plate, and the other end is provided with a connection plug. A plurality of cables distributed at equal angles are inserted and fixed on the connection plate. The MQ4 connection head is provided with a plug-in part matching the cables.

Detailed Embodiment

[0015] To make the technical solutions and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0016] As Figure 1 shown, an MQ4 connector includes an MQ4 connection head 1. A connecting plate 11 is provided at one end of the MQ4 connection head 1, and a connection plug 17 is provided at the other end. The connecting plate 11 serves to install and fix the MQ4 connector, and the connection plug 17 serves to connect an external connector.

[0017] It should be noted that a plurality of cables 15 distributed at equal arcs are plugged and fixed on the connecting plate 11. The cables 15 distributed at equal arcs have an orderly distribution, thus reducing the operation difficulty, so that the MQ4 connector achieves the purpose of significantly reducing the requirements for connector sequence and topological arrangement and effectively reducing the design cost. At the same time, a plug-in part 14 matching the cable 15 is arranged on the MQ4 connection head 1. The plug-in part 14 is used to maintain a fixed connection structure with the cable 15, and can adopt methods such as welding, clamping, buckling, etc., and in the embodiment of the present application, it is welding, which has the effects of reducing the installation and fixing difficulty and maintaining the stability and durability of the installation and fixing. Among them, one end of the cable 15 is inserted from one end of the plug-in part 14 close to the connecting plate 11 and is connected to the connection plug 17 from the other end of the plug-in part 14. Therefore, the cable 15 will first maintain a stable paired connection structure with the MQ4 connection head 1 on the MQ4 connector, and the multiple orderly distributions effectively reduce the requirements for connector sequence and topological arrangement. Furthermore, when the MQ4 connector is applied, it will be effectively used in the complex azimuth connections with uneven topological arrangements and inconsistent installation positions, achieving the purpose of effectively reducing the design cost.

[0018] As Figure 1 shown, one end of the plug-in part 14 passes through the connecting plate 11 and is used to sleeve the outside of the cable 15, and a sealing ring groove 13 is arranged outside the connecting plate 11 and located outside the plug-in part 14. An installation sealing ring 2 is arranged in the sealing ring groove 13, and the connecting plate 11 is provided with a plurality of connecting holes 12 located at the corners. The connecting holes 12 are externally connected and fixed through fasteners such as plug-in fixing bolts. The sealing ring groove 13 improves the fixing stability of the installation sealing ring 2, so that after the connecting plate 11 is installed and fixed externally, the installation sealing ring 2 will effectively improve the waterproof effect between the cable 15 and the connecting plate 11. At the same time, an external sealing ring 16 is sleeved on the middle part of the MQ4 connection head 1, so that when the connection plug 17 is connected to an external device, the waterproof effect between the MQ4 connection head 1 and the external device will be improved, and the stability of the cable 15 during use will be improved.

[0019] As Figure 1 、 Figure 2 shown, a plug-in cavity 171 is arranged in the connection plug 17. The plug-in cavity 171 is used to connect with the external connector of the external device, so as to realize the orderly and stable connection of the circuit. At the same time, a plurality of plug-in connection heads 18 respectively connected to the corresponding cables 15 are arranged in the plug-in cavity 171. The plug-in connection heads 18 are used to connect with the external connector, effectively reducing the operation difficulty.

[0020] It should be noted that multiple mating slots 172 are provided in the insertion cavity 171, which are distributed at equal radian and extend along the length direction of the insertion cavity 171, and a limiting ring groove 19 for communicating with the inner end of the mating slot 172. Among them, the mating slot 172 is for the external connector to be inserted. In the embodiment of the present application, the external connector has external protrusions that match the mating slot 172 and the limiting ring groove 19, so that after the external protrusion is inserted into the insertion cavity 171 along the mating slot 172, it gradually moves towards the limiting ring groove 19, and further realizes the anti - detachment effect of the external connector by matching with the limiting ring groove 19. Among them, the anti - detachment is realized by using an elastic material or an elastic snap structure, which will not be elaborated here. At the same time, a sealing embedded groove 191 for plug - in sealing with the external connector is provided on the outer side of the insertion connection head 18, so as to form a high pressure inside by increasing the contact area and air extrusion to prevent liquid from seeping in.

[0021] In summary, the present application provides an MQ4 connector. The MQ4 connector is directly connected and fixed to the cable through the connection plug 17, thereby effectively reducing the requirements for the connector sequence and topological arrangement. During the operation, it is only necessary to directly connect the inner core of the cable, effectively reducing the operation difficulty and design cost.
