[0002] Cable accessories are products that connect cables to power transmission and distribution lines and related power distribution devices, such as intermediate joints. The intermediate joints need to be molded with the help of molding equipment during the production process; during the operation, the rubber is first filled into the mold cavity, and then molded into cable accessories; in this process, if the temperature of the mold exceeds 50°C, the rubber may be damaged, so it needs to be cooled; the existing cooling method generally requires the use of a quick connector to inject coolant into the accommodating cavity of the molding equipment to achieve heat exchange between the coolant and the mold, thereby preventing the temperature of the rubber in the mold from exceeding 50°C. The quick connector in the prior art generally includes an input pipe arranged on one side of the molding equipment, and an output pipe arranged on the other side of the molding equipment. The coolant is introduced into the molding equipment from the input pipe to exchange heat with the rubber, and then the rubber after heat exchange flows out through the output pipe. This installation method requires two installation positions for installing the output pipe and the input pipe on the molding equipment, which increases the workload and occupies the installation space. In addition, the pipeline is generally welded on the molding equipment, so both welding heads need to have good sealing performance to prevent coolant leakage, which increases the difficulty of processing.

[0030] The working principle of the utility model is:

[0031] During installation, the first connector 1 or the second connector 2 can be installed on the molding device. Taking the first connector 1 as an example, the output end of the first connector 1 can be welded or threadedly connected to the molding device. As long as the connection between the first connector 1 and the molding device does not leak liquid after connection, there are many ways of connection.

[0032] In order to illustrate the design concept of the present application, as Example 1, taking the first joint 1 connected to the molding equipment as an example, when the rubber on the molding equipment needs to be cooled, the second joint 2 is connected to the first joint 1 through a locking mechanism. After installation, the first input channel 11 and the second input channel 21 are in a conductive state, and the first output channel 12 and the second output channel 22 are in a conductive state. The input end of the second input channel 21 of the second joint 2 is connected to the coolant, and the coolant first flows into the second input channel 21 and then flows into the first input channel 11; since the first input channel 11 and the accommodating cavity on the molding equipment are in a conductive state, the coolant enters the accommodating cavity, and since the temperature of the coolant is lower than the temperature of the rubber, the heat of the rubber will be exchanged to the coolant in the accommodating cavity, and since the first output channel 12 is conductive with the accommodating cavity, the coolant after heat exchange will flow into the first output channel 12 and finally flow out through the second output channel 22. The present application is coordinated by a locking mechanism and other structures. When the first connector 1 is connected to the second connector 2 through the locking mechanism, the first input channel 11 is connected to the second input channel 21, and the first output channel 12 is connected to the second output channel 22. The second delivery channel is connected to the coolant. The coolant flows into the accommodating cavity through the second input channel 21 and the first input channel 11 in turn to cool the mold. The coolant after heat exchange flows out through the first output channel 12 and the second output channel 22 in turn. The above-mentioned coolant can be realized by cooling oil or cooling water. During the whole process, only the first connector 1 needs to be connected to the molding equipment, that is, only one installation position needs to be opened on the molding equipment, and the two-way flow of the liquid is realized through the quick connector of the present application; it replaces the two installation positions opened in the molding equipment in the prior art, saves installation space, reduces processing difficulty, and is conducive to promotion and application. In the above technology, the present application uses the cooling liquid as an example, which does not mean that the quick connector of the present application is only applicable to cooling operations; for example, when the material in the reactor needs to be heated or kept warm, the first connector 1 is connected to the reactor. The design principle is consistent with the above, and only the heat source needs to be connected to the second input channel 21, such as hot water. Figure 2 As shown in the figure, the direction of the arrow is the flow direction of the liquid. Figure 2 The part marked by A is a molding device for producing cable accessories. The first outer tube can be threadedly connected to the molding device to achieve conduction between the first joint and the accommodating cavity of the molding device.

[0033] In the above technical solution, taking the rubber cooling of the middle joint as an example, when the rubber cooling process is completed, the connection between the first joint 1 and the second joint 2 can be released by the locking mechanism. As embodiment 1, the design concept with the spring as the matching is as follows: first, the second joint 2 is pressed in the direction close to the first joint 1 (because a spring is arranged between the first joint 1 and the second joint 2, and the spring is arranged in the mounting part 1-3, it is in a compressed state at this time. When the pressing force is cancelled, the spring restores the deformation and drives the second joint 2 to move away from the first joint 1. At this time, the steel ball 31 leaves the annular groove 23), and then the second joint 2 is pulled away from the first joint 1 or an external force is applied to the second joint 2 by a power device such as a telescopic cylinder or a telescopic motor, so that the second joint 2 is separated from the first joint 1, thereby releasing the connection between the first joint 1 and the second joint 2. The locking mechanism switches the first joint 1 and the second joint 2 to a conducting state, or makes the first joint 1 and the second joint 2 in a blocked state, so that the design can control the injection or disconnection of the liquid, that is, the heat source or the coolant mentioned above. As embodiment 2, there is no need to set a spring in the mounting portion 1-3, and the second connector 2 is directly pulled to move away from the first connector 1, so that the steel ball 31 leaves the annular groove 23, thereby separating the second connector 2 and the first connector 1. The material of the first connector 1 is selected as a plastic part, and the first connector 1 has a certain elasticity so that when the steel ball is inserted into or removed from the annular groove, the first connector is not damaged.

[0034] On the basis of the above technical solution, the first input channel 11 and the second input channel 21 can be respectively opened on the first inner tube 1-2 and the second inner tube 2-2. Figure 2 As shown; the space jointly enclosed by the second installation cavity and the outer periphery of the second inner tube 2-2 constitutes the second output channel 22; the space jointly enclosed by the first installation cavity and the outer periphery of the first inner tube 1-2 constitutes the first output channel 12.

[0035] On the basis of the above technical solution, in order to prevent the first input channel 11 and the second input channel 21 from being offset when docking, the present application provides a mounting portion 1-3 on the first input channel 11, and a plug-in portion 2-3 on the second input channel 21. The plug-in portion 2-3 is plugged into the mounting portion 1-3 to facilitate the quick docking of the first connector 1 and the second connector 2 during installation.

[0036] On the basis of the above technical solution, the present application may also provide a sealing ring 4 at the connection between the first joint 1 and the second joint 2, for example, at the connection between the mounting portion 1-3 and the plug-in portion 2-3, so that the leakage of liquid can be prevented.

[0037] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
