Description

Technical Field

[0001] This utility model relates to the field of connector testing technology, and in particular to an insulator depth testing device for connectors. Background Technology

[0002] As a core component of modern communication systems, aerospace equipment, and high-end electronic products, the performance of radio frequency (RF) connectors directly affects signal transmission quality and system reliability. Among these parameters, the depth from the insulator to the connector body is a critical structural parameter that directly impacts electrical characteristics (such as impedance matching and signal attenuation) and mechanical mating performance (such as insertion / extraction force and sealing). If this parameter exceeds design tolerances, it can lead to increased signal reflection, electromagnetic shielding failure, or wear at the contact interface, ultimately causing serious problems such as communication interruptions and equipment overheating.

[0003] Traditional inspection methods primarily rely on manual operation of mechanical dial indicators or depth micrometers, involving manual positioning, contact with the measuring point, and reading the scale value. However, manual operation is inefficient, requiring individual clamping and multiple measurements with averaging, which is difficult to meet the needs of mass production. Furthermore, differences in operator skill can easily lead to problems such as probe tilting and uneven pressure, resulting in poor measurement repeatability and the risk of human error. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an insulator depth detection device for connectors, which can quickly and accurately measure the depth of the insulator relative to the body in the connector, avoiding measurement errors caused by human factors.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: an insulator depth detection device for connectors, comprising: a base plate, a clamping assembly disposed on the base plate, a frame, a dial indicator disposed on the frame, and a material screening assembly. The clamping assembly is used to clamp and transport the connector to be tested. The probe of the dial indicator is in partial contact with the insulator of the connector to measure the depth of the insulator relative to the body. The material screening assembly transfers the tested connector from the clamping assembly to a designated position.

[0006] Preferably, the clamping assembly includes a linear module, clamping jaws, and a positioning plate. The linear module is mounted on the base plate, the clamping jaws are mounted on the linear module, and the positioning plate is mounted on the clamping jaws. The positioning plate has a positioning hole that mates with the connector, and the axis of the positioning hole is located between the two jaws of the clamping jaws.

[0007] Preferably, a reference positioning post is provided on the base plate. The reference positioning post cooperates with the positioning plate and supports the position of the connector. When the material is loaded, one end of the connector passes through the positioning hole and abuts against the reference positioning post, thereby facilitating the clamping claws to hold the connector.

[0008] Preferably, a vertical sliding assembly is connected to the dial indicator. The vertical sliding assembly includes a first slide plate and a first driving member. The first slide plate slides vertically on the frame, the first driving member is disposed on the frame and drives the first slide plate to move, and the dial indicator is disposed on the first slide plate.

[0009] Preferably, the material feeding and screening assembly includes a material feeding cylinder, a material feeding pusher, and a screening rod. A second sliding plate is provided on the frame. The material feeding cylinder and the screening rod are both located on the second sliding plate. The material feeding pusher is connected to the piston rod of the material feeding cylinder. The diameter of the screening rod is smaller than the inner diameter of the connector body at the end equipped with the contact spring and larger than the minimum inner diameter of the contact spring. The material feeding pusher disengages the connector on the screening rod from the screening rod.

[0010] Preferably, the feeding pusher head has a feeding port with a diameter larger than the diameter of the screen rod and smaller than the size of the main body of the connector near the feeding pusher head, so as to detach the connector on the screen rod from the screen rod.

[0011] Preferably, a second drive unit is provided on the frame, and the piston rod of the second drive unit is connected to the second slide plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. The operator places one end of the connector to be tested through the positioning hole onto the reference positioning post, and then the clamping jaws clamp the connector, thereby avoiding subsequent measurement errors caused by the placement error of the connector, and achieving accurate measurement through a dial indicator;

[0014] 2. Further inspection of connectors is conducted using a material screening component to check for missing contact springs, thereby improving the connector inspection process. Attached Figure Description

[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0031] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0032] Unless otherwise specified, physical quantities in formulas should be understood as basic quantities of SI base units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.

[0033] Example:

[0034] refer to Figures 1-3 An insulator depth testing device for connectors includes: a base plate 1, a clamping assembly mounted on the base plate 1, a frame 2, a dial indicator 41 mounted on the frame 2, and a screening assembly. The frame 2 is mounted on the base plate 1. The clamping assembly is used to clamp and transport the connector to be tested. The probe of the dial indicator 41 contacts a portion of the connector's insulator, and the sleeve portion of the dial indicator 41 abuts against one end of the connector body, thereby enabling the dial indicator 41 to measure the depth of the insulator relative to the body. The screening assembly cooperates with the clamping assembly to transfer the tested connector from the clamping assembly to a designated position.

[0035] refer to Figures 1-3 The clamping assembly includes a linear module 31, clamping jaws 32, and a positioning plate 33. The linear module 31 is mounted on the base plate 1, and the clamping jaws 32 are mounted on the linear module 31, allowing the linear module 31 to move the clamping jaws 32 left and right. The clamping jaws 32 can be finger cylinders. The positioning plate 33 is bolted to the main body of the clamping jaws 32. The positioning plate 33 has a positioning hole 331 that mates with the connector, and the axis of the positioning hole 331 is located between the two jaws of the clamping jaws 32. A reference positioning post 6 is mounted on the base plate 1. The reference positioning post 6 mates with the positioning plate 33 and supports the position of the connector. When loading, one end of the connector passes through the positioning hole 331 and abuts against the reference positioning post 6, thus facilitating the positioning and clamping of the connector by the clamping jaws 32.

[0036] refer to Figure 1 and Figure 2 To control the position of dial indicator 41 and make its probe contact the connector, a vertical sliding assembly is connected to dial indicator 41. The vertical sliding assembly includes a first slide plate 42 and a first drive member 43. The first drive member 43 can be a cylinder. The first slide plate 42 slides vertically up and down on the frame 2 via a slider. The first drive member 43 is bolted to the frame 2. The first slide plate 42 is connected to the piston rod of the first drive member 43, so the first drive member 43 drives the first slide plate 42 to move. The dial indicator 41 is bolted to the first slide plate 42, so the first drive member 43 drives the dial indicator 41 to move vertically up and down, thereby making the probe of dial indicator 41 contact the upper end face of the connector's insulator, thus measuring the depth between the insulator and the body.

[0037] refer to Figures 1-3The material feeding and screening assembly includes a feeding cylinder 51, a feeding pusher 52, and a screening rod 53. A second sliding plate 54 is mounted on the frame 2. Both the feeding cylinder 51 and the screening rod 53 are mounted on the second sliding plate 54. The feeding pusher 52 is connected to the piston rod of the feeding cylinder 51. The diameter of the screening rod 53 is smaller than the inner diameter of the connector body at the end with the contact spring but larger than the minimum inner diameter of the contact spring. Thus, when the connector does not have a missing contact spring, the screening rod 53 inserts into the inner diameter of the contact spring, causing the contact spring to deform and adhere to the screening rod 53. At this time, even if the clamping jaws 32 release the connector, the connector will not fall off because it is clamped on the screening rod 53. Therefore, the connector can be detached from the screening rod 53 by the feeding pusher 52 and fall into the designated collection area. If the contact spring is missing, the connector cannot adhere to the screening rod 53. At this time, the clamping jaws 32 will release, and the connector will fall off the clamping jaws 32. This allows for the screening of connectors that are missing contact springs. The feeding push head 52 has a feeding port 521. The diameter of the feeding port 521 is larger than the diameter of the screening rod 53 and smaller than the size of the connector body near the feeding push head 52. Thus, the feeding cylinder 51 drives the feeding push head 52 to move downward, pushing the connector attached to the screening rod 53 outward and causing it to fall into the designated area.

[0038] refer to Figures 1-3 To facilitate control of the position of the screening rod 53, a second drive component 55 and a third drive component 56 are bolted to the frame 2. The second drive component 55 and the third drive component 56 can be cylinders. The piston rod of the second drive component 55 is connected to the second slide plate 54, thereby controlling the vertical position of the second slide plate 54 and consequently the vertical position of the screening rod 53. The second drive component 55 can be mounted on the third drive component 56, allowing the third drive component 56 to control the horizontal position of the screening rod 53, thus enabling the connector to be lowered to a designated area.

[0039] Operation process: The linear module 31 operates, moving the clamping jaws 32 and the positioning plate 33 above the reference positioning post 6, with the positioning hole 331 facing the reference positioning post 6. The operator places the lower end of the connector to be tested through the positioning hole 331 onto the reference positioning post 6. Then, the clamping jaws 32 move and clamp the connector. The linear module 31 then moves the clamping jaws 32, which clamps the connector, below the dial indicator 41. The first drive unit 43 operates, moving the dial indicator 41 toward the connector and making the probe contact the insulator, thereby measuring the depth from the insulator to the body.

[0040] Then the linear module 31 continues to move, moving the clamping jaws 32 holding the connector below the screen rod 53. The second drive unit 55 operates, inserting the screen rod 53 into one end of the connector. The clamping jaws 32 release. If the connector does not have a missing contact spring, the connector will adhere to the screen rod 53 and will not fall off. Driven by the unloading cylinder 51, the unloading push head 52 will detach the connector from the screen rod 53 and place it in the designated area. If the contact spring is missing, the connector cannot adhere to the screen rod 53, and the connector will fall off directly when the clamping jaws 32 release.
