[0002] Cable connectors are widely used in power distribution and electronic and electrical equipment. Their main function is to fix cables, prevent water or dust from entering the box, and ensure safe and reliable operation of the equipment. Most existing cable connector designs have waterproof and breathable functions. They can be sealed and waterproof to avoid damage to components and performance degradation, and can also be breathable to prevent internal gas from expanding due to heat and endangering the life and safety of components. Therefore, waterproof and breathable cable connectors have been widely used in the market.

[0003] At present, in the manufacturing process of waterproof and breathable cable connectors, the film pressing process is an important step to achieve the waterproof and breathable function.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The core of the utility model is to provide a jig, which can improve the processing efficiency and processing quality of products.

[0031] It should be noted that in the present embodiment, the orientation or position relationship indicated by "upper", "lower", etc. is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0032] Please refer to Figures 1 to 5 The present application provides a jig, including an upper mold member 1 and a lower mold member 2, the upper mold member 1 is provided with at least one row of flush pressing heads 13, the top of the pressing head 13 is inserted into the upper mold member 1 and flexibly connected thereto, and the bottom of the pressing head 13 extends downward from the bottom end of the upper mold member 1; the lower mold member 2 is correspondingly arranged below the lower mold member 2, and the lower mold member 2 is provided with at least one row of flush limiting grooves 21, and the limiting grooves 21 are arranged one by one opposite to the pressing heads 13.

[0033] Specifically, the upper film component is located above the lower mold component 2, and the two are arranged oppositely. A plurality of pressure heads 13 are arranged side by side along the length direction of the upper mold component 1 to form a row of pressure heads 13, and the number of pressure heads 13 in a row of pressure heads 13 is not unique, and is selected and set according to actual processing requirements, and the number of rows of pressure heads 13 can be set to two or more rows, and arranged along the width direction of the upper mold component 1, so as to be suitable for the film pressing process of a large number of cable connectors, which can greatly improve the processing efficiency. The upper mold component 1 is provided with a plurality of jacks, and the number of the plurality of jacks is consistent with the number of the plurality of pressure heads 13, and the bottom end position of the jack corresponding to the upper mold component 1 is open, and the pressure head 13 is inserted into the jack and flexibly connected to the closed end of the jack. Specifically, the flexible connection can be achieved by a spring and an elastic sleeve, etc., and the form is not unique, as long as the pressure head 13 has a certain displacement along its axial direction, and the pressure head 13 extends downward through the open end of the jack for a distance, which is used to press the waterproof breathable membrane. The plurality of limit grooves 21 are arranged side by side along the length direction of the lower mold member 2 to form a row of limit grooves 21. The plurality of limit grooves 21 are arranged opposite to the plurality of rams 13 one by one, and the number of rows of limit grooves 21 is consistent with the number of rows of rams 13. In addition, the plurality of rams 13 are arranged flush so that the length of the protruding section of the ram 13 extending out of the bottom end of the upper mold member 1 is consistent. Accordingly, the plurality of limit grooves 21 are arranged flush so as to unify the downward pressing stroke of the plurality of rams 13, facilitate the precise control and driving of the press equipment, and avoid the ram 13 from moving downward too much and damaging the waterproof breathable membrane.

[0034] The present application is applied to the film pressing process of cable connectors. When in use, the jig is placed in the working area of ​​the press equipment. First, a cable connector stacked with a waterproof and breathable membrane is placed in each limit groove 21 to position the cable connector to prevent it from shaking. Then the press equipment is used to drive the upper membrane component to move downward. Each pressure head 13 moves downward toward the limit groove 21 directly opposite to it, and presses the waterproof and breathable membrane to fit on the cable connector to complete the film application of multiple cable connectors at the same time. It should be noted that since the top of the pressure head 13 is flexibly connected to the upper mold member 1, the pressure head 13 has a certain displacement along its axial direction. In this way, in the process of the pressure head 13 pressing the waterproof and breathable membrane, it can be avoided that the pressure head 13 moves downward too much and damages the waterproof and breathable membrane. Therefore, compared with manual pressing, the present application can improve processing efficiency and reduce labor costs. In addition, the downward pressure exerted on the pressure head 13 is a constant value and is not affected by human factors, thereby ensuring that the waterproof and breathable membrane is subjected to uniform force. The pressure head 13 adopts a flexible connection to ensure that the waterproof and breathable membrane is not easily damaged, thereby improving product processing quality.

[0035] In addition, each limiting groove 21 in the lower mold member 2 is adapted and snap-fitted with the cable connector to be filmed, so as to limit the shaking of the cable connector. Since the upper mold member 1 and the lower mold member 2 are separate structures, the lower mold member 2 can be replaced at any time according to cable connectors of different specifications so that the limiting groove 21 is adapted and snap-fitted with the cable connector. Even if the present application is applicable to the film pressing process of cable connectors of various specifications, it has a wide coverage.

[0036] In order to realize the automatic control of the present application, on the basis of the above embodiment, the top of the upper mold member 1 is connected to a driving member, and the driving member can be a servo motor, a cylinder or an oil cylinder, as long as it can drive the upper mold member 1 to rise and fall. In this way, by controlling the opening and closing of the driving member, the pressing action of the jig of the present application can be realized, and there is no need to manually carry the jig back and forth to the press equipment.

[0037] In order to be suitable for the film pressing process of cable connectors of different specifications, on the basis of the above embodiment, the lower mold component 2 includes a lower mold body and a limiting plate. The limiting plate is detachably arranged on the lower mold body, and a limiting groove 21 is provided on the limiting plate so that the limiting groove 21 can be detachably installed on the lower mold body through the limiting plate. In this way, the limiting groove 21 adapted to the cable connector can be replaced at any time according to the specifications of the cable connector to meet the processing of cable connectors of different specifications, and the replacement method is convenient.

[0038] Optionally, the same limiting plate is provided with limiting grooves 21 of different sizes so as to simultaneously process cable connectors of different specifications.

[0039] Considering the specific implementation method of the flexible connection between the pressure head 13 and the upper mold member 1, based on the above embodiment, please refer to Figure 3 and Figure 5The upper mold component 1 includes an upper mold cover plate 11 and an upper mold body 12 . The upper mold cover plate 11 is detachably covered on the top of the upper mold body 12 . The pressing head 13 penetrates the upper mold body 12 and is arranged on the upper mold cover plate 11 through an elastic member 14 .

[0040] Specifically, the upper mold component 1 is composed of an upper mold cover plate 11 and an upper mold body 12 to form a detachable structure, which is convenient for installing components in the upper mold component 1 and preventing impurities from entering and damaging the components. The upper mold body 12 is provided with a through hole, and the upper mold cover plate 11 is provided with a fixing groove directly opposite to the through hole. The fixing groove is connected with the through hole to form the above-mentioned jack. The pressure head 13 is located in the through hole, and its bottom extends downward out of the through hole, and an elastic member 14 is sleeved on the top of the pressure head 13. The elastic member 14 is fixed in the fixing groove so that the pressure head 13 is connected to the upper mold cover plate 11 through the elastic member 14. In this way, the elastic member 14 not only allows the pressure head 13 to have a certain axial displacement to protect the waterproof breathable membrane from damage, but also isolates the pressure head 13 from the upper mold cover plate 11 to reduce the friction between the two, thereby preventing the pressure head 13 from being misaligned, and further ensuring that the pressure head 13 performs the pressing action normally.

[0041] Furthermore, the elastic part 14 is a metal elastic part 14, such as a spring made of metal material. The metal elastic part 14 has good elastic deformation ability, vibration isolation ability and structural strength. The metal elastic part 14 maintains a relatively constant spring force within a certain deformation range, and can stably transmit the punching force to the pressure head 13, provide reliable support, and enable multiple pressure heads 13 to maintain good flatness. When the bottom end of the pressure head 13 is punched onto the waterproof breathable membrane, the metal elastic part 14 plays a good vibration isolation role, preventing the top end of the pressure head 13 from damaging the upper mold cover plate 11, so as to further prevent the pressure head 13 from being misaligned.

[0042] Based on the above examples, please refer to Figure 1 , Figure 3 and Figure 5 Positioning pins 15 are connected between the corners of the upper mold cover plate 11 and the upper mold body 12 to improve the connection tightness between the upper mold cover plate 11 and the upper mold body 12 on the basis of realizing the detachable connection between the upper mold cover plate 11 and the upper mold body 12.

[0043] Based on the above examples, please refer to Figures 1 to 3 The upper mold component 1 is provided with a plurality of guide columns 17, which extend downwardly in a direction parallel to the axis of the pressing head 13. The lower mold component 2 is provided with a plurality of mounting holes 22, which are opposite to the guide columns 17 and are inserted and adapted.

[0044] Specifically, the guide column 17 is inserted on the upper mold body 12, and the lower mold member 2 is provided with a mounting hole 22 adapted for the insertion of the guide column 17, and the downward extension direction of the guide column 17 is parallel to the axial direction of the pressure head 13, so that the guide column 17 plays a guiding role. Through the guiding role of the guide column, the upper mold member 1 and the lower mold member 2 are correctly matched to correct and align the position of the pressure head 13 and the limit groove 21 to ensure the normal operation of the fixture.

[0045] On the basis of the above embodiment, a plurality of guide columns 17 are arranged in a triangular shape around all the pressing heads 13, so that when the guide columns 17 are inserted into the mounting holes 22, the upper mold component 1 and the lower mold component 2 are aligned, and the guide columns 17 arranged in a triangular shape can provide stable support for the upper mold component 1.

[0046] On the basis of the above embodiments, a plurality of limit blocks 16 are provided at the bottom end of the upper mold member 1 , or a plurality of limit blocks 16 are provided at the top end of the lower mold member 2 .

[0047] Specifically, Figure 2 As shown, a limit block 16 is provided at the bottom of the upper mold body 12. Preferably, four limit blocks 16 are provided, and the four limit blocks 16 are distributed at the four corners of the bottom of the upper mold body 12. Alternatively, a limit block 16 is provided at the top of the lower mold member 2. Preferably, four limit blocks 16 are provided, and the four limit blocks 16 are distributed at the four corners of the top of the lower mold member 2. In this way, the limit block 16 can limit a certain distance between the upper mold member 1 and the lower mold member 2 to prevent the pressing block from crushing the surface of the cable connector and the waterproof breathable membrane.

[0048] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above is a detailed introduction to a jig provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model.
