Description

Technical Field

[0001] The present invention relates to the technical field of workpiece fixtures, and in particular to a clamping fixture for terminal processing. Background Art

[0002] A connector, also known as a plug, a connector, and a socket, generally refers to an electrical connector, that is, a device connecting two active devices to transmit current or signals. During the preparation of a connector, pins need to be inserted into a resin housing in an orderly manner. The traditional pin insertion method generally uses manual insertion for single-piece pin insertion, and the other is to use a pin insertion machine for automatic pin insertion, so as to smoothly insert the pins into the resin housing.

[0003] When inserting pins, a fixture that can stably clamp the resin housing is required to ensure the stable progress of pin insertion. However, the traditional fixture is not firmly clamped, resulting in the resin housing being easily displaced during the pin insertion process, which affects the qualified rate of the finished product to a certain extent. In addition, only one specification of placement groove is opened on the traditional fixture, and resin housings of various different types cannot be placed, resulting in troublesome processing and the need to frequently replace the matching fixture. Summary of the Invention

[0004] In order to overcome the deficiency that the existing fixture lacks a limiting mechanism, the present invention provides a clamping fixture for terminal processing, and solves the problem by providing a plurality of placement grooves with elastic limiting blocks of different specifications.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a clamping fixture for terminal processing, including a fixture substrate and two side shells. A plurality of placement grooves for placing connection housings are opened on the fixture substrate, and each placement groove can place a connection housing of one specification. A plurality of positioning and locking members for positioning the connection housing are provided inside the side shells, the positioning and locking members are arranged corresponding to the placement grooves, and the end of the positioning and locking member presses against the connection housing placed in the placement groove. The two side shells are respectively detachably arranged on both sides of the fixture substrate.

[0006] According to this solution, by opening a plurality of placement grooves of different specifications, different housings can be placed, and the positioning and locking members are used to stably push against the housings, so that the pin insertion has good stability and high efficiency.

[0007] Furthermore, the positioning and locking member includes a limiting block, a mounting seat, and an elastic connecting member. The mounting seat is sleeved on the sliding rod, a limiting block is fixedly arranged at one end of the mounting seat, and the other end is connected to the side shell through the elastic connecting member.

[0008] According to this solution, the limiting block slides inside the side shell through the elastic connecting member and limits and pushes against the connection housing.

[0009] Further, the limiting block includes an upper clamping plate and a lower clamping plate formed on the side surface of the mounting seat. The upper clamping plate abuts against the upper surface of the connection housing, and the lower clamping plate abuts against the side surface of the connection housing. A clamping groove is formed between the upper clamping plate and the lower clamping plate.

[0010] According to this solution, to avoid damage to the resin shell by the limiting block, the upper clamping plate and the lower clamping plate are used to abut and fix it from the upper surface and the side surface of the connection housing to ensure stable clamping.

[0011] Further, the end of the upper clamping plate is planar or serrated.

[0012] According to this solution, different types of upper clamping plates can be selected according to the connection housing with different pin requirements, which does not interfere with the pins while ensuring stable clamping.

[0013] Further, a dial is provided on the mounting seat for driving the displacement of the mounting seat, and an adjustment groove for the dial to move is correspondingly opened on the side shell.

[0014] According to this solution, when it is necessary to loosen the connection housing, it can be unlocked by manually operating the dial, which is convenient and fast.

[0015] Further, a sliding rod for driving the sliding of the positioning locking member is provided inside the side shell, and a plurality of positioning locking members are provided on the sliding rod.

[0016] According to this solution, the sliding rod is used to drive the limiting blocks arranged on the same side to slide synchronously to perform the action of abutting against or loosening the connection housing.

[0017] Further, a guiding groove for the positioning locking member to slide is opened on one side of the jig substrate close to the placement groove.

[0018] According to this solution, the mounting seat of the positioning locking member is slidably arranged in the guiding groove, and the connection housing can be accurately pushed against the placement groove.

[0019] Further, extension sections are provided at both ends of the sliding rod, and the extension sections extend out of the side shell and are sleeved with adjusting wheels. Corresponding strip-shaped grooves for the horizontal displacement of the extension sections are opened on both end faces of the side shell.

[0020] According to this solution, the sliding rod is driven to displace along the strip-shaped groove by the adjusting wheel to perform the action of abutting against or loosening the connection housing.

[0021] Further, a clamping groove for facilitating the clamping of the resin shell is provided on the outer edge of the placement groove, and the clamping groove is communicated with the placement groove.

[0022] According to this solution, by reserving the clamping groove, it is convenient to take out the finished terminals from the placement groove.

[0023] The beneficial effects of the present invention are

[0024] (1) By means of a substrate provided with a number of placement grooves of different specifications, the stable placement of the resin shell is achieved, and the resin shell is limited and pushed by an elastic limiting block to prevent its displacement during the processing, so as to ensure the stability of the pin insertion. Multiple connection shells of different specifications can be inserted with pins in one operation, effectively improving the pin insertion efficiency;

[0025] (2) By arranging movable shafts on both sides of the substrate, the limiting members in the placement grooves on the same side can be driven to move horizontally. When the limiting members on both sides move towards the middle of the substrate, the resin shell in the placement groove is limited, and when the limiting members on both sides move towards the outside of the substrate, the resin shell in the placement groove is released;

[0026] (3) By setting the end of the limiting block to be flat or serrated, the resin shell can be effectively limited and fixed without damaging the resin shell, ensuring the stability of its clamping. Description of the Drawings

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0036] As Figure 1 is a schematic structural diagram of the present invention. A clamping fixture for terminal processing includes a fixture substrate 1 and two side shells 4. A plurality of placement grooves 2 for placing connection shells are provided on the fixture substrate 1. Each placement groove 2 can place a connection shell of a certain specification. A plurality of positioning and locking members 3 for positioning the connection shell are provided in the side shell 4. The positioning and locking members 3 are arranged corresponding to the placement grooves 2. The end of the positioning and locking member 3 presses against the connection shell placed in the placement groove 2. The two side shells 4 are respectively detachably arranged on both sides of the fixture substrate 1.

[0037] After placing the resin shell to be needle-inserted in the placement groove 2, the resin shell is pushed and abutted in the placement groove 2 by the positioning and locking member 3 in the placement groove 2 for limit fixation. Moreover, the specifications of the placement grooves 2 are different, and the needle-inserting operations of resin shells of multiple different specifications can be completed in one clamping, with high efficiency.

[0038] The positioning and locking member 3 includes a limit block 31, a mounting seat 32, and an elastic connecting member 33. The mounting seat 32 is sleeved on the sliding rod 5. One end of the mounting seat 32 is fixedly provided with the limit block 31, and the other end is connected to the side shell 4 through the elastic connecting member 33. Under the action of the elastic connecting member 33, the mounting seat 32 slides in the side shell 4 to realize the clamping and loosening of the resin shell.

[0039] The limit block 31 includes an upper clamping plate 311 and a lower clamping plate 312 formed on the side surface of the mounting seat 32. The upper clamping plate 311 abuts against the upper surface of the connection shell, and the lower clamping plate 312 abuts against the side surface of the connection shell. A clamping groove 313 is formed between the upper clamping plate 311 and the lower clamping plate 312. To avoid damage to the resin shell by the limit block 31, the resin shell is abutted and fixed from its upper surface and side surface by the upper clamping plate 311 and the lower clamping plate 312 to ensure the stable clamping of the resin shell.

[0040] As Figure 2 and 3 shown, the end of the upper clamping plate 311 is flat or serrated. The serrated clamping plate can avoid the needles on the resin shell during clamping, and stably clamp the resin shell without damaging the needles on the resin shell.

[0041] A guide groove 11 for the positioning and locking member 3 to slide is provided on one side of the fixture substrate 1 close to the placement groove 2. The mounting seat 32 slides stably in the guide groove, and can accurately push the connection shell into the placement groove 2.

[0042] The mounting base 32 is provided with a paddle 321 for driving the displacement of the mounting base 32, and a corresponding adjustment groove 41 for the paddle 321 to move is formed on the side shell 4. The paddle 321 and the mounting base 32 are of an integral structure, and the mounting base 32 with the paddle 321 moves in the adjustment groove 41 under the action of the elastic connecting piece 33.

[0043] As Figure 6 shown, a sliding rod 5 for driving the positioning and locking member 3 to slide is arranged inside the side shell 4, and a plurality of positioning and locking members 3 are arranged on the sliding rod 5. The sliding rod 5 drives the positioning and locking members 3 on the same side to perform synchronous sliding to limit or unlock the connection of the outer shell.

[0044] As Figure 4 shown, extension sections are arranged at both ends of the sliding rod 5, the extension sections extend out of the side shell 4 and are sleeved with adjusting wheels 51, and corresponding strip-shaped grooves 42 for the horizontal displacement of the extension sections are formed on the end faces of both ends of the side shell 4. When an external force acts to move the adjusting wheel 51 along the strip-shaped groove 42 outward, the sliding rod 5 drives the limiting block 31 to move towards the side of the side shell 4, compressing the elastic connecting piece 33. The elastic connecting piece 33 is a spring, the limiting block 31 retracts, the resin shell loosens, and when the external force is removed, the limiting block 31 extends into the placement groove 2 under the action of the elastic connecting piece 33 to stably clamp the resin shell placed in the placement groove 2.

[0045] As Figure 5 shown, a clamping groove 21 for facilitating the clamping of the resin shell is arranged on the outer edge of the placement groove 2, and the clamping groove 21 communicates with the placement groove 2. The clamping groove 21 is pre-opened on the outer edge of the placement groove 2 to facilitate the removal of the resin shell from the placement groove 2 by a mechanical claw after the needle insertion is completed. Wedge surfaces are arranged on the upper edges of the placement groove 2 and the clamping groove 21 to facilitate the insertion of the resin shell or the mechanical claw.

[0046] The above description is illustrative rather than restrictive to the present invention. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all of them will fall within the protection scope of the present invention.
