本发明涉及电连接器领域，特别是涉及到了一种隔爆连接器组件。The invention relates to the field of electrical connectors, in particular to a flameproof connector assembly.
背景技术Background technique
隔爆连接器组件是一种主要用于隔爆箱体上的电连接器，与普通的电连接器相比，隔爆连接器组件的插座与防爆箱体的配合处的密封性有着更高的要求。现有隔爆箱体用的隔爆连接器插座主要有两种安装形式：圆筒接合面安装和螺纹接合面安装。The explosion-proof connector assembly is a kind of electrical connector mainly used on the explosion-proof box. Compared with the ordinary electrical connector, the sealing of the socket of the explosion-proof connector assembly and the explosion-proof box has a higher sealing performance. requirements. There are mainly two types of installation forms for the flameproof connector socket used in the existing flameproof box: cylinder joint surface installation and thread joint surface installation.
圆筒接合面安装：由于圆筒结合面对配合面的间隙要求严格，而隔爆箱体与隔爆连接器插座往往是在不同的地方生产，这就给隔爆箱体的制造精度提出了更高的要求，给隔爆箱体的制造方带来了很大困难，使隔爆箱体与隔爆连接器插座的最终配合间隙较难控制；另外，现常规的采用圆筒接合面的隔爆连接器插座往往不带附件，使产品的应用范围受到限制，只能用于容积较小的隔爆箱体。Cylinder joint surface installation: Due to the strict requirements on the gap between the cylinder joint surface and the mating surface, the flameproof box and the flameproof connector socket are often produced in different places, which poses a challenge to the manufacturing accuracy of the flameproof box. The higher requirements have brought great difficulties to the manufacturer of the flameproof box, making it difficult to control the final matching gap between the flameproof box and the flameproof connector socket; in addition, the conventional use of cylindrical joints Flameproof connector sockets often do not have accessories, which limits the application range of the product and can only be used in flameproof boxes with small volumes.
螺纹接合面安装：现有采用螺纹接合面安装结构的隔爆连接器插座的螺纹加工在和其一体的套筒或方盘上，使用时与隔爆箱体上加工的相应螺纹配合。因此，在装配时隔爆连接器插座需要随着螺纹的旋合而转动，但是此时隔爆连接器已接好线，因此会给操作带来很大困难；另外，因螺纹旋到位后隔爆连接器插座的实际方位不好确定，给后续隔爆连接器的后续插合使用带来了不便。Threaded joint surface installation: the thread of the existing flameproof connector socket with threaded joint surface installation structure is processed on the sleeve or square plate integrated with it, and cooperates with the corresponding thread processed on the flameproof box when used. Therefore, the flameproof connector socket needs to be rotated with the screwing of the thread during assembly, but at this time the flameproof connector has been connected, so it will bring great difficulties to the operation; The actual position of the explosion-proof connector socket is not easy to determine, which brings inconvenience to the subsequent mating and use of the subsequent explosion-proof connector.

为了解决上述问题，隔爆连接器组件采用以下技术方案：隔爆连接器组件，包括插头和插座，插头和插座各自以前端为插接端，插头包括插头壳体，插座包括插座壳体和附件，附件包括套筒，所述插座壳体为方盘壳体，方盘壳体的方盘上设有连接孔，连接孔用于和相应的防爆箱体固定连接，附件的套筒前端设有用于与隔爆箱体上的安装孔螺纹连接的外螺纹，插座壳体的后端插入至套筒中，套筒的前端处设有与插座壳体的外周面密封配合的防爆接合面。In order to solve the above problems, the flameproof connector assembly adopts the following technical scheme: the flameproof connector assembly includes a plug and a socket, the plug and the socket each use the front end as the insertion end, the plug includes a plug housing, and the socket includes a socket housing and accessories , the accessory includes a sleeve, the socket housing is a square plate shell, and the square plate of the square plate shell is provided with a connecting hole, which is used for fixed connection with the corresponding explosion-proof box, and the front end of the sleeve of the accessory is provided with a The rear end of the socket housing is inserted into the sleeve, and the front end of the sleeve is provided with an explosion-proof joint surface that is sealingly matched with the outer peripheral surface of the socket housing.
套筒与插座壳体的外壁面之间设有密封圈。A sealing ring is provided between the sleeve and the outer wall of the socket housing.
所述套筒的内孔为包含有一前一后设置的大、小径段的台阶孔，插座壳体的后端插入至套筒的内孔的大径段中，大径段的长度不小于插座壳体的可插入套筒的部分的长度。The inner hole of the sleeve is a stepped hole including a large diameter section and a small diameter section arranged one after the other, the rear end of the socket housing is inserted into the large diameter section of the inner hole of the sleeve, and the length of the large diameter section is not less than the socket The length of the portion of the housing into which the sleeve is inserted.
由于本发明的隔爆连接器组件的插座的壳体的方盘上设有连接孔，附件的套筒上设有外螺纹，因此，在使用的时候，可通过连接孔壳体与隔爆箱体固定连接，通过套筒的外螺纹与隔爆箱体固定连接，同时以套筒的与隔爆箱体的配合的部分作为与隔爆箱体的接合面，保证密封，通过螺纹与隔爆箱体配合的隔爆连接器插座则降低了对隔爆箱体的加工精度要求；与此同时，插合在一起的壳体与套筒的配合处形成防爆接合面，从而从整体上保证隔爆连接器插座与隔爆箱体的密封配合，而壳体及套筒在连接器领域中均是由连接器厂家生产，更易于保证二者之间的匹配性，综上所述，本发明的隔爆连接器组件的插座降低了隔爆连接器插座对隔爆箱体加工精度的要求，同时解决了现有隔爆连接器组件操作不便的问题。Since the square plate of the housing of the socket of the flameproof connector assembly of the present invention is provided with a connection hole, and the sleeve of the accessory is provided with an external thread, therefore, when in use, the housing and the flameproof box can be connected through the connection hole. The body is fixedly connected, and the outer thread of the sleeve is fixedly connected with the flameproof box. At the same time, the part of the sleeve that matches the flameproof box is used as the joint surface with the flameproof box to ensure sealing. The explosion-proof connector socket matched with the box reduces the processing accuracy requirements for the explosion-proof box; The sealing fit between the explosion connector socket and the flameproof box body, and the shell and the sleeve are both produced by the connector manufacturer in the field of connectors, which is easier to ensure the matching between the two. In summary, the present invention The socket of the flameproof connector assembly reduces the requirements of the flameproof connector socket on the processing accuracy of the flameproof box, and at the same time solves the problem of inconvenient operation of the existing flameproof connector assembly.
