Description

Technical Field

[0001] The present invention relates to the technical field of tooling for assembling an electric connector, and in particular to an assembly tool for post-assembly of a spring sheet of an electric connector. Background Art

[0002] An electrical connector is a device used to achieve electrical and mechanical connections between circuits. Its basic structure includes a mounting plate with an insulating structure and a contact body with a spring structure. The contact body is the core of the connector, which can provide reliable electrical connections during connection and disconnection, ensuring stable transmission of signals and power.

[0003] The spring as the contact body of the electrical connector needs to be assembled with the mounting plate. There are two installation methods during the installation process: 1. Before the spring is installed, except for the arc-shaped three-dimensional structure of the spring contact part, the whole body is a straight plate structure. When installing, take the plug-in end of the mounting plate as the front end and the pin arrangement end of the mounting plate as the rear end, and pass through the corresponding slot of the mounting plate from front to back, and then perform L-shaped bending on the installed spring to achieve installation.

[0004] 2. Before installation, bend the spring into an L-shaped structure in advance. When installing, take the plug-in end of the mounting plate as the front end and the pin arrangement end of the mounting plate as the rear end, and pass it through the corresponding slot of the mounting plate from back to front to achieve installation.

[0005] Currently, the installation of pre-bent L-shaped springs mainly relies on manual operation, that is, the staff manually inserts the springs from the corresponding slots of the mounting plate from the back to the front. However, due to the large variety of springs, different forming shapes, and a large number of pins, it is difficult for the staff to operate during installation, and it is easy to cause the pressing size of the springs to be unstable, and the consistency of each spring cannot be guaranteed, resulting in unstable installation accuracy, thereby affecting product quality. Summary of the invention

[0006] The technical purpose of the present invention is to provide an assembly tool for the rear installation of electric connector springs which is simple to operate and can simultaneously press multiple springs into the mounting plate with the same pressing size, in view of the particularity of the above-mentioned electric connector springs being installed from back to front in the corresponding slots of the mounting plate and the shortcomings of the prior art.

[0007] The technical solution adopted by the present invention is as follows: An assembly tool for post-installation of an electrical connector spring, the assembly tool comprising a base plate positioning seat and a pressure plate positioning seat arranged in an open / closed matching relationship; The substrate positioning seat is used to fix the mounting plate of the electrical connector, and the pin arrangement end of the fixed mounting plate is oriented toward the pressure plate positioning seat, and the pin arrangement end of the mounting plate is pre-installed with a corresponding spring sheet; The pressure plate positioning seat is used as a fixed pressure plate, and the pressure plate is used to press the corresponding spring piece into the mounting plate of the electrical connector. The pressure plate has a press-fitting end that matches the corresponding spring piece, and the press-fitting end faces the substrate positioning seat; Between the substrate positioning seat and the pressure plate positioning seat, there are positioning columns arranged in the opening and closing direction and constraining the relative position of the closing movement.

[0008] The above-mentioned technical measures are aimed at the particularity that the electric connector spring is installed from back to front in the corresponding slot of the mounting plate. By fixing the electric connector mounting plate pre-installed with the corresponding spring on the substrate positioning seat, and fixing the pressure plate with the pressing end matching the corresponding spring on the pressure plate positioning seat, the substrate positioning seat and the pressure plate positioning seat are arranged in an opening / closing matching relationship, and the substrate positioning seat and the pressure plate positioning seat perform a closing movement, and the pressing end of the pressure plate matching the corresponding spring presses down the corresponding spring, so that each spring is pressed in at the same time; by arranging a positioning column between the base positioning seat and the pressure plate positioning seat to constrain the relative position of the closing movement, the downward pressing size of each spring in the mounting plate can be flexibly controlled according to actual needs.

[0009] The above technical measures are easy to operate and can realize the simultaneous pressing of each reed, while ensuring that each reed is subjected to consistent force during the pressing process, so that the pressed dimensions of each reed in the mounting plate are consistent, which is conducive to ensuring product quality.

[0010] Furthermore, the substrate positioning seat and the pressure plate positioning seat of the assembly tool are arranged in an upper and lower position, the substrate positioning seat is in a lower position, and the pressure plate positioning seat is in an upper position. The pressure plate positioning seat uses the substrate positioning seat as a movement reference, the pressure plate positioning seat moves upward to increase the matching distance with the substrate positioning seat, and the pressure plate positioning seat moves downward to close the matching distance with the substrate positioning seat.

[0011] In the above technical measures, the substrate positioning seat and the pressure plate positioning seat are arranged in an upper and lower position, the substrate positioning seat is at the lower side, and the pressure plate positioning seat is at the upper side. The opening or closing movement is achieved by the up and down movement of the pressure plate positioning seat to realize the pressing installation of each spring leaf.

[0012] Furthermore, the positioning posts of the assembly tool are multiple groups arranged at intervals along the length direction of the assembly tool, and these positioning posts are connected to the pressure plate positioning seat, and the substrate positioning seat has abutment areas that cooperate with the positioning posts.

[0013] In the above technical measures, the positioning column is connected to the pressure plate positioning seat, and the substrate positioning seat has a contact area that cooperates with the positioning column. When the substrate positioning seat and the pressure plate positioning seat are closed, the positioning column cooperates with the contact area of ​​the matching positioning column on the substrate positioning seat, which can accurately control the downward pressure size of each spring leaf in the mounting plate, which is beneficial to improving the installation accuracy.

[0014] Furthermore, the positioning posts are arranged in two groups at intervals, and the two groups of positioning posts are distributed at both ends of the length direction of the pressure plate positioning seat, and are located at the left and right ends of the pressure plate connected to the pressure plate positioning seat; There is a clearance for the mounting plate between each group of positioning columns and the adjacent pressing plate.

[0015] In the above technical measures, the positioning columns are divided into two groups arranged at intervals. These two groups of positioning columns are distributed at both ends in the length direction of the pressure plate positioning seat, and are located at the left and right ends of the pressure plate connected to the pressure plate positioning seat, which can improve the stability of the spring post-installation operation; each group of positioning columns and the adjacent pressure plate have a clearance for the mounting plate to ensure the stability of the closing movement. When there is no clearance for the mounting plate, the positioning columns cannot abut and cooperate with the abutting area with the matching positioning columns on the base plate positioning seat, thereby affecting the downward pressure of each spring leaf and affecting the product quality.

[0016] Furthermore, the pressure plate positioning seat has a pressure plate limiting plate and a pressure plate abutting plate stacked together; A through T-slot is provided in the thickness direction of the pressure plate limiting plate, the small end of the T-slot faces the substrate positioning seat, and the large end is connected to the pressure plate abutting plate; The pressure plate abutting plate is stacked on the pressure plate limiting plate in a detachable structure, the stacking matching surface of the pressure plate abutting plate at least partially covers the large end of the T-slot on the pressure plate limiting plate, and the pressure plate abutting plate abuts and limits the corresponding pressure plate installed in the pressure plate limiting plate; Correspondingly, the pressing plate connected to the pressing plate positioning seat is a T-shaped structure, the pressing plate of the T-shaped structure passes through the T-slot on the pressing plate limiting plate, and the pressing end of the pressing plate extends toward the substrate positioning seat.

[0017] The above-mentioned technical measures can realize the limitation and fixation of the pressure plate; the stacked mating surface of the pressure plate abutment plate at least partially blocks the large end of the T-slot on the pressure plate limiting plate, thereby preventing the pressure plate from shifting due to the upward force during the pressing process, thereby preventing the pressing failure; the pressure plate abutment plate is stacked on the pressure plate limiting plate with a detachable structure, and the pressure plate installed on the pressure plate limiting plate can be replaced by disassembling the pressure plate abutment plate, thereby meeting the installation requirements of different spring leaves.

[0018] Furthermore, the press-fitting end of the press plate connected to the press plate positioning seat has at least one set of press contacts of a U-shaped forked structure; The crimping contact points match the convex step shoulders on both sides of the corresponding spring sheet in the width direction; Correspondingly, the two sides of the spring sheet in the width direction have fins with an outwardly protruding structure, which are used for inserting and limiting cooperation with the mounting plate.

[0019] In the above technical measures, the crimping contact points of the press-fitting end match the protruding step shoulders on both sides of the corresponding spring leaf in the width direction, ensuring that the spring leaf will not shift during the pressing process, which is conducive to precise press-fitting.

[0020] Furthermore, the pressure plate connected to the pressure plate positioning seat is divided into multiple pieces corresponding to different structural springs of the electrical connector, and these pressure plates are combined side by side in the length direction of the pressure plate positioning seat.

[0021] The above technical measures adapt to the installation requirements of different springs through the design of multiple pressure plates.

[0022] Furthermore, the surface of the substrate positioning seat facing the pressure plate positioning seat has a positioning cavity with an inner concave structure for embedding the plug-in end of the mounting plate. The positioning cavity has a guide plate with a protruding shape, which is inserted into the plug-in end of the fixed mounting plate; Correspondingly, the springs installed in the mounting plate of the electrical connector are two layers with an electrical plug-in gap. When the springs of the electrical connector are assembled, the guide plate extends into the plug-in end of the mounting plate to separate and position the two layers of springs installed at the electrical plug-in gap.

[0023] The above-mentioned technical measures are achieved by providing a positioning cavity with a concave structure on the surface of the base plate positioning seat facing the pressure plate positioning seat, which is used to embed the plug-in end of the mounting plate, and providing a convexly formed guide plate in the positioning cavity, which is inserted into the plug-in end of the fixed mounting plate. When the spring leaf is pressed and moved, it can guide the spring leaf, ensuring the correct alignment of each spring leaf during the pressing process, which is beneficial to improving the installation accuracy.

[0024] Furthermore, the substrate positioning seat has a substrate limiting plate and a guide plate passing plate stacked together, and the substrate limiting plate is arranged close to the pressure plate positioning seat; The substrate limiting plate is provided with a positioning cavity with an inner concave structure in the thickness direction, which matches the contour of the corresponding mounting plate plug-in end; The guide plate penetration plate corresponds to the area of ​​the positioning cavity and is provided with a through slot in the thickness direction. The guide plate passes through the through slot on the guide plate penetration plate and extends into the positioning cavity.

[0025] Furthermore, the through slot on the guide plate through-mounting plate is a T-slot, the small end of the T-slot is in the positioning cavity, and the large end is away from the substrate limiting plate; Correspondingly, the guide plate connected to the substrate positioning seat is a T-shaped structure, the guide plate of the T-shaped structure passes through the T-slot on the guide plate mounting plate, and the guide function area of ​​the guide plate is located in the positioning cavity.

[0026] The above technical measures can achieve the limitation of the guide plate and the mounting plate, which is beneficial to improving stability.

[0027] Furthermore, the substrate positioning seat also has a guide plate abutting plate; The guide plate abutting plate is stacked on the guide plate wearing plate, and the stacking matching surface of the guide plate abutting plate at least partially blocks the large end of the T-slot on the guide plate wearing plate.

[0028] In the above technical measures, the overlapping mating surface of the guide plate abutting the plate at least partially blocks the large end of the T-slot on the guide plate passing plate, which can prevent the guide plate from being displaced by the downward force during the pressing process of the spring leaf, thereby preventing the pressing failure of the spring leaf.

[0029] Further, the assembly tool is arranged on a punch press; The base plate positioning seat of the assembly tool is fixed on the working table of the punch press, and the pressure plate positioning seat of the assembly tool is connected to the machine head of the punch press.

[0030] The above technical measures can arrange the assembly tooling on the punch press, and can use the punch press to realize the up and down movement of the pressure plate positioning seat, which is beneficial to improving the automation level and improving work efficiency.

[0031] Furthermore, the spring of the electrical connector is an L-shaped bending structure before being assembled in the mounting plate; A spring slot is provided in the mounting plate of the electrical connector for the corresponding spring to pass through from the back to the front.

[0032] In the above technical measures, the reed is an L-shaped bending structure before assembly, and does not need to rely on the structure of the mounting plate for guided bending, thereby simplifying the installation process of the reed.

[0033] One or more technical solutions provided by the present invention have at least the following technical effects or advantages: In view of the particularity that the springs of the electric connector are installed from back to front in the corresponding slots of the mounting plate, the present invention fixes the electric connector mounting plate pre-installed with the corresponding springs on the substrate positioning seat, and fixes the pressing plate with the pressing end that matches the corresponding springs on the pressing plate positioning seat. The substrate positioning seat and the pressing plate positioning seat are arranged in an opening / closing matching relationship. The substrate positioning seat and the pressing plate positioning seat perform a closing movement, and the pressing end of the pressing plate that matches the corresponding spring presses down the corresponding spring, thereby achieving simultaneous pressing in of each spring. By arranging a positioning column between the base positioning seat and the pressing plate positioning seat to constrain the relative position of the closing movement, the pressing size of each spring in the mounting plate can be flexibly controlled according to actual needs.

[0034] The present invention is easy to operate and can realize simultaneous pressing of various springs, while ensuring that the springs are subjected to consistent forces during the pressing process, so that the pressing dimensions of the springs in the mounting plate are consistent, which is beneficial to ensuring product quality.

DETAILED DESCRIPTION

[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those within the scope of this description. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1 See also Figure 1 As shown, the connector of the present invention comprises a mounting plate formed of an insulating material and a plurality of groups of springs formed of a metal conductive material.

[0039] Specifically, the mounting plate comprises an upper wall plate and a lower wall plate, and a plurality of partition walls (including a vertical wall plate whose end is between the upper wall plate and the lower wall plate) arranged at intervals along the horizontal width direction (i.e., the left-right direction relative to the pin arrangement end / plug-in end) between the upper wall plate and the lower wall plate. These partition walls separate a plurality of groups of insertion slots for inserting spring sheets between the upper wall plate and the lower wall plate.

[0040] In the mounting plate, between the adjacent left and right partition walls (i.e., in the horizontal width direction) of each insertion slot for inserting the spring sheet, there is a layer plate that divides the insertion slot into relatively independent insertion spaces in the upper and lower parts (the aforementioned upper and lower positions are relative to the top and bottom heights of the mounting plate). In this way, between the adjacent left and right partition walls of each insertion slot for inserting the spring sheet, there are two groups of slots that are layered and relatively independent in the upper and lower parts. It should be specially noted that the molding positions of the partition walls and layer plates of the mounting plate are located in the middle and rear part of the front-to-back direction of the mounting plate (i.e., the direction between the pin arrangement end and the plug-in end). The insertion slots at the front part of the mounting plate (i.e., the plug-in end) are connected in the horizontal width direction so that the supporting equipment and the spring sheet can form an electrical connection during use.

[0041] Each group of springs is composed of an inner spring and an outer spring. The inner spring has an integrally formed base, a contact portion located at the front of the base (relative to the pin arrangement end / plug-in end of the mounting plate), and a pin portion located at the rear of the base (relative to the pin arrangement end / plug-in end of the mounting plate). To adapt to the electrical connection and plugging in use, the contact portion is an upward (relative to the top and bottom heights of the mounting plate) arc-shaped curved structure that matches the outer spring. Of course, the contact portion can also be bifurcated in the horizontal width direction. To adapt to the crimping assembly relationship between the printed circuit board, the pin portion is provided with a vertical elliptical micro-deformation hole, similar to a "fish eye". This type of spring is also known as a fish eye spring in the industry. Of course, the fish eye structure on the same spring can be formed in multiple forms of bifurcations. In order to enable the inner spring to be accurately and stably assembled in the corresponding slot of the mounting plate, the base at the front side of the bending part has a fixed small wing with a convex shape and a tooth-shaped structure on both sides of the horizontal width.

[0042] The outer layer spring has an integrally formed base body 2, a contact part 2 located at the front of the base body 2, and a pin part 2 located at the rear of the base body 2. To adapt to the electrical connection plugging and unplugging during use, the contact part 2 is a downward arc-shaped bending structure that matches the inner layer spring. Before being assembled on the mounting plate, the outer layer spring is pre-bent from the middle and rear of the base body 2 into an L-shaped bending structure. In order to enable the outer layer spring to be accurately and stably assembled in the corresponding slot of the mounting plate, the base body 2 at the front side of the bending part has two fixed small wings with a convex shape and a tooth-shaped structure on both sides of the horizontal width.
