Description

Technical Field

[0001] The utility model relates to the technical field of injection-molded housing structures for drivers, in particular to an injection-molded housing structure for a driver. Background Art

[0002] The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator. In the national standard GB5095, it is called mechanical operation. It is based on one insertion and one removal as a cycle. The judgment basis is whether the connector can normally complete its connection function after the specified insertion and removal cycle. The injection molded shell structure of the connector is the most important fixed connection component, which requires a dedicated injection molded shell structure for the driver.

[0003] Currently, most drive housing structures are fixed by means of clamping strips and slots on both sides, which have the advantages of simple structure and reliable operation.

The right ends of the male shell card strips 6 are provided with locking holes, and the rear ends of the locking screws are installed in cooperation with the locking holes located in the same horizontal plane. When the left side of the female shell 8 is inserted into the male shell 1, the female shell guide block 11 is engaged with the male shell guide groove 5, and the female shell card block 9 is engaged with the male shell slot 4. Then the male shell card strip 6 is loosened, and the right end of the male shell card strip 6 is deep into the female shell slot 10 and engaged. Then the locking screw is rotated until it penetrates the locking hole at the right end of the male shell card strip 6 for deeper fixation. At this time, the locking screws at both ends complete the longitudinal locking of the female shell 8, and also include a locking mechanism 12;

[0024] The locking mechanism 12 comprises a card block 121 and a spring 122. The card block 121 is respectively slidably connected to the through holes on the left side of the upper and lower inner walls of the male shell groove 2. The spring 122 is respectively fixedly connected between the inner wall of the male shell through hole and the side of the card block 121 away from the center of the male shell groove 2. The spring 122 is located inside the through hole. When the left end of the female shell card strip 7 penetrates into the interior of the male shell groove 2, the card block 121 is squeezed to slide to the side away from the center of the male shell groove 2. The spring 122 is squeezed and contracted until the card block 121 is squeezed and corresponds to the bayonet of the female shell card strip 7 up and down. The spring 122 rebounds and resets, pushing the card block 121 to engage with the bayonet of the female shell card strip 7.

[0025] Among them: it also includes a female shell card strip 7, the female shell card strip 7 is symmetrically arranged on the front and rear surfaces of the female shell 8, the left end of the female shell card strip 7 is provided with a bayonet that is engaged with the card block 121, and also includes a positioning groove 3, the positioning groove 3 is symmetrically opened on the front and rear surfaces of the male shell 1, the female shell card strip 7 is provided with a positioning strip on one side close to the center of the female shell 8, the positioning strips are installed in conjunction with the horizontally adjacent positioning grooves 3, the left end of the female shell card strip 7 is provided with an avoidance port, and the left end of the side of the male shell card strip 6 away from the center of the male shell 1 and the right end of the side of the female shell card strip 7 away from the center of the female shell 8 are both It is provided with friction patterns. With the help of the friction patterns on the left end of the male shell card strip 6, the left side of the male shell card strip 6 is pressed to facilitate the male shell card strip 6 to slightly tilt and pry it open. With the help of the friction patterns on the female shell card strip 7, it is easy to push the female shell card strip 7 and the male shell 1 to the left. The female shell card strips 7 on both sides of the female shell 8 are inserted into the positioning grooves 3 on both sides of the male shell 1 through the inner positioning strips. The avoidance opening at the left end of the female shell card strip 7 provides avoidance for the protrusion inside the positioning groove 3, until the left end of the female shell card strip 7 corresponds to the male shell groove 2 on both sides of the male shell 1 front and back, and then penetrates into the inner wall of the male shell groove 2 due to elastic deformation.

[0026] The working principle of the injection molded housing structure for a driver provided by the present invention is as follows: when using the injection molded housing structure for the driver, first fix the female terminal inside the female housing block 9 in the female housing 8, and fix the male terminal inside the male housing slot 4 in the male housing 1. The right side of the male housing 1 is aligned with the left side of the female housing 8. Then, the left side of the female housing 8 is inserted into the right side of the male housing 1. At this time, the female housing clips 7 on both sides of the female housing 8 are inserted into the positioning slots 3 on both sides of the male housing 1 through the inner positioning strips. The avoidance opening at the left end of the shell card strip 7 provides avoidance for the protrusion inside the positioning groove 3, until the left end of the female shell card strip 7 corresponds to the male shell groove 2 on both sides of the male shell 1 front and back, and then it penetrates into the inner wall of the male shell groove 2 due to elastic deformation. (During the sliding process of the left side of the female shell card strip 7, the left end of the female shell card strip 7 fails to deform inward due to contact with the male shell 1, until the left end of the female shell card strip 7 corresponds to the male shell groove 2 on both sides of the male shell 1 front and back, the length and width of the left end of the female shell card strip 7 are greater than The length and width of the left end of the female shell card strip 7, the left end of the female shell card strip 7 is elastically deformed and penetrates into the inner wall of the male shell groove 2). When the left end of the female shell card strip 7 penetrates into the interior of the male shell groove 2, the extrusion block 121 slides to the side away from the center of the male shell groove 2, and the spring 122 is squeezed and contracted until the extrusion block 121 corresponds to the bayonet of the female shell card strip 7 up and down, and the spring 122 rebounds and resets, pushing the extrusion block 121 to engage with the bayonet of the female shell card strip 7. When the left side of the female shell 8 is inserted into the male shell 1, With the help of the friction pattern on the left end of the male shell card strip 6, press the left side of the male shell card strip 6, and the male shell card strip 6 will be slightly tilted and opened. When the left side of the female shell 8 is inserted into the male shell 1, the female shell guide block 11 is engaged with the male shell guide groove 5, and the female shell card block 9 is engaged with the male shell card slot 4. Then, release the male shell card strip 6, and the right end of the male shell card strip 6 will penetrate into the female shell card slot 10 and be engaged. Then, rotate the locking screw until it penetrates the locking hole at the right end of the male shell card strip 6 for deeper fixation. At this time, the locking screws at both ends complete the longitudinal locking of the female shell 8.
