[0002] Terminals are an important part of connectors. Connectors use terminals of different shapes according to their size. For convenience, terminals are usually designed to have the same structure. When the connector is small, only one terminal is needed. When the connector is large, only two terminals need to be snapped together to use it. This allows a common set of molds to be used, saving production costs. However, the terminals are usually small and need to be aligned with the snapping position during the snapping process. The manual snapping method not only has a slow operation process and affects production efficiency, but also has the problem of inadequate snapping and fixing, affecting the connector's yield rate.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figure 1-5 ;

[0025] The buckling fixture described in the present invention is intended to improve the buckling speed of the two terminals while ensuring their fixing effect to meet the production requirements of the next process. First, it is necessary to explain the structure of the terminal, which specifically includes a buckling portion 72, a plurality of PIN pins 71 are inserted into the buckling portion 72, and the buckling portion 72 is injection molded. A plurality of "T"-shaped card slots 73 and a card block 74 on one side of the card slot 73 are provided above the buckling portion 72. The buckling method of the two terminals is that the card block 74 of one terminal is clamped with the card slot 73 of the other terminal; when these terminals are used alone, a card block 74 adapted to the card slot 73 should be provided on the housing of the connector for fixing; The snap-fitting fixture described in the new invention includes a fixed seat 1, on which are provided two parallel feeding channels 1 21 and 22 with a height difference, and the ends of feeding channel 1 21 and feeding channel 2 22 are provided with snap-fitting positions 23, and a limiting structure is provided at the position corresponding to the snap-fitting position 23; it should be noted that the height of feeding channel 1 21 and feeding channel 2 22 should be adapted to the snap-fitting portion 72 of the terminal, so as to avoid jumping during the feeding process, which causes the terminal to be offset, and the positions of the snap-fitting positions 23 of the two feeding channels should be provided with openings for the terminals to be placed therein, and in one embodiment of the limiting structure, it is an "L"-shaped limiting block.

[0026] During operation, one terminal is placed upright in the second feeding channel 22, that is, the card slot 73 faces upward, and then the other terminal is placed upside down in the first feeding channel 21, that is, the card slot 73 faces downward, so that the buckling positions 23 of the two terminals are in relative positions. In addition, due to the height difference between the first feeding channel 21 and the second feeding channel 22, the terminal located in the second feeding channel 22 is at the bottom, and the terminal located in the first feeding channel 21 is at the top, but the buckling positions 23 of the two terminals are overlapped on the same plane to achieve buckling;

[0027] A first ejector rod 41 is provided in the first feeding channel 21, and the first ejector rod 41 is connected to the first ejector assembly 42. A second ejector rod 51 is provided in the second feeding channel 22, and the second ejector rod 51 is connected to the second ejector assembly 52. Of course, before the terminal is placed in the feeding channel, the two ejector rods extend out of the feeding channel to avoid affecting the placement of the terminal. A pushing assembly 6 is provided at the position corresponding to the fastening position 23. In this embodiment, the specific structures of the first ejector assembly 42, the second ejector assembly 52 and the pushing assembly 6 are not limited, that is, manual pushing or automatic pushing can be used, and both can achieve corresponding technical effects. Of course, automated action can reduce the number of action steps of the staff and improve efficiency.

[0028] In this embodiment, the ejection assembly 1 42 and the ejection assembly 2 52 have the same structure. The ejection assembly 1 42 includes a cylinder 1 421. The output end of the cylinder 1 421 is connected to a slider 422. The slider 422 is connected to the sliding pair 423. The ejector rod 1 41 is fixedly connected to the slider 422. The pushing assembly 6 includes a cylinder 2 61. The output end of the cylinder 2 61 is provided with a push rod 62. The push rod 62 extends through the fixed seat 1 to the buckling position 23. The lower end of the push rod 62 is provided with a locking position 63 adapted to the buckling portion 72.

[0029] First, the ejector assembly 1 42 and the ejector assembly 2 52 push the ejector rod 1 41 and the ejector rod 2 51 respectively, so that the ejector rod 1 41 and the ejector rod push the two terminals to slide along the loading channel 1 21 and the loading channel 2 22 respectively, and the two terminals finally enter the snap-fit position 23. At this time, the "L"-shaped limit block is used to limit the stroke of the two terminals so that the two terminals are aligned parallel. In addition, a protrusion is provided near one end of the two loading channels. The protrusion and the limit block are combined to form a limit channel at the snap-fit position 23, so that one terminal can maintain parallel alignment when pushed to the other terminal. Then, the pushing assembly 6 is used to push the terminal near the loading channel 1 21 to the terminal near the loading channel 2 22, so that the snap-fit parts 72 of the two terminals are engaged with each other. The position of the terminal is also limited by the other end of the "L"-shaped limit block to prevent the terminal from flying out of the snap-fit position 23. After completion, the pushing assembly 6 is reset, and the snap-fit position 23 is exposed and the terminal can be taken out from the snap-fit position 23.

[0030] The utility model can realize the quick snap-fit connection of two terminals through the above structure without the need for alignment operation. Compared with the method of needing to find the snap-fit position 23 of the two terminals before manual operation, the speed is faster, and the stroke of the pushing component 6 to push one terminal to the other terminal is fixed. At the same time, the snap-fit position of the terminals is limited, which can ensure that the quality of the snap-fit of the two terminals meets the requirements each time the operation is carried out, avoiding the subsequent assembly of the connector being affected by the quality problems of the terminals.

[0031] The present invention further describes the limiting structure, specifically including a limiting block 31 corresponding to the output direction of the pushing component 6, that is, after the pushing component 6 pushes one terminal toward the other terminal, the two terminals contact the limiting block 31 to complete the fastening process, and a gate component 32 corresponding to the output direction of the ejection component 2 52. The gate component 32 is used to open and close the output port 324. In this embodiment, the ejection component 2 52 is a segmented output.

[0032] The ejection assembly 1 42, the ejection assembly 2 52, the pushing assembly 6 and the gate assembly 32 in this embodiment are all pneumatically operated and automated by the controller, that is, the staff only needs to seal the two terminals and place them in the two feeding channels; the ejection assembly 2 52 is divided into two stages of ejection. First, the terminal located in the feeding channel 2 2 is pushed into the snap-fit position 23. At this time, the gate assembly 32 closes the output port 324 to prevent the terminal from being pushed out so that the two terminals can be aligned. In addition, a protrusion 33 is provided at one end near the two feeding channels. The protrusion 33 is opposite to the lower end of the gate assembly 32. The snap-fit position 23 forms a limiting channel so that one terminal can maintain parallel alignment when pushed to the other terminal; after the two terminals are snapped together, the gate assembly 32 is lifted to expose the output port 324, and the ejection assembly 2 52 pushes the connected terminal to the output port 324. Located on the outside of the jig can prevent the collection box, and the terminal can fall into the collection box from the output port 324.

[0033] Furthermore, the gate assembly 32 includes a fixed block 321, a cylinder three 322 is provided above the fixed block 321, the output end of the cylinder three 322 is connected to the movable block 323, the pressure block passes through the fixed block 321, and the fixed block 321 is provided with an output port 324 at the position corresponding to the buckling position 23.

[0034] Feeding channel 1 21 and feeding channel 2 22 have the same structure. In order to enable the terminal to move more smoothly in the feeding channel and avoid displacement, in this embodiment, a limiting groove 24 is provided in feeding channel 1 to limit the snap-fit portion 72 of the terminal. The snap-fit portion 72 and the limiting groove 24 form a sliding pair structure, which can not only play a limiting role, but also enable it to move smoothly.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
