Description

Technical Field

[0001] This utility model relates to the field of contact groove measurement, and in particular to a device for checking the depth difference of electrical connector pins inserted into the contact groove. Background Technology

[0002] Cable mesh assemblies are electrical or signal transmission connection devices, typically composed of cables and electrical connectors. When the micro-rectangular connectors of cable mesh assemblies transmit electrical or signal power to connectors on other equipment, inconsistencies in the insertion depth of the male pins and female contact slots directly affect the reliability of the electrical or signal transmission performance of the cable mesh assembly in various equipment applications, potentially leading to product quality issues. Different manufacturers of micro-rectangular connectors may have varying dimensional tolerances in the male pins, female contact slots, and connector insulator holes, as well as different assembly processes, which can easily result in insufficient insertion depth, increased resistance, and insufficient insertion and extraction force. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for checking the depth difference of the insertion of the pins of an electrical connector into the contact slots. It helps to detect the depth difference between the contact slots on the female connector to determine whether it meets the requirements of processing consistency. If the depth difference between the contact slots is too large, it is easy to cause the pins to be affected by the shallow contact slots, resulting in insufficient insertion depth of the entire male connector, so as to determine whether the electrical connector needs to be replaced.

[0004] To solve the above problem, a depth difference inspection device for the insertion of electrical connector pins into the contact slot is adopted, which includes:

[0005] A depth dial indicator includes a head, a bushing at the bottom of the head, a measuring rod inside the bushing, the measuring rod extending out of the bushing, and a measuring head below the measuring rod.

[0006] A sleeve, which is inserted into a bushing;

[0007] The bolt is tightened by threading through a sleeve and pressing against the bushing.

[0008] A bracket having a first crossbar fixed to a sleeve;

[0009] The base is fixed to the lower end of the bracket;

[0010] The XY axis moving platform is fixed on the base;

[0011] A clamp, mounted on an XY-axis moving platform, for holding the female head of an electrical connector;

[0012] The pins are inserted into the contact slots of the female connector, and they are adapted to the contact slots, with their upper ends extending out of the contact slots.

[0013] The truncated cone-shaped pin cap is fixed to the upper end of the pin. It is narrow at the top and wide at the bottom, and the sloping surface facilitates the climbing of the measuring head.

[0014] Using this structure, pins of known specifications are inserted into the initial contact slot to their deepest point. A frustum-shaped pin cap is then placed against the bottom surface of the depth dial indicator's measuring head. The indicator is then zeroed, and the measuring rod is in a pre-compression state. The initial contact slot serves as the reference surface. The pin is then pulled out and inserted into the second contact slot to its deepest point. The pin is moved using an XY-axis platform, and the frustum-shaped pin cap is used to re-engage the measuring head. If the second contact slot is shallow, the second insertion will raise the measuring head, making the measured surface higher than the reference surface, resulting in a negative reading. Conversely, if the second contact slot is deeper, the measuring rod will descend, causing the indicator to display a positive value. The principle is to transform the bottom surface of the contact slot, which is difficult to measure, into the top surface of the frustum-shaped pin cap, which is easier to measure, thereby obtaining a relative difference. If some contact slots are too shallow, it may cause insufficient pin insertion depth for other male connectors; in this case, the electrical connector should be replaced.

[0015] The tightening bolt can secure the inserted depth dial indicator.

[0016] As a further improvement of this utility model, the bracket includes:

[0017] The base plate is fixed to the base.

[0018] The first lead screw is rotatably connected to the base;

[0019] A smooth rod, spaced apart from the first lead screw and fixed to the base plate;

[0020] The top plate is fixed to the upper end of the guide rod and rotatably connected to the upper end of the first lead screw;

[0021] A handle, which is fixed to the upper end of the first lead screw;

[0022] The slider slides through the guide rod;

[0023] A threaded block, whose threads are connected to the first lead screw;

[0024] The second crossbar has a threaded block fixed at one end and a slider fixed at the other end.

[0025] With this structure, the threaded block can be moved up and down by turning the handle, which makes it easy to adjust the initial height of the depth gauge.

[0026] As a further improvement of this utility model, the XY-axis moving platform includes:

[0027] The X-axis slide rail is fixed on the base, and the top surface of the slide rail has a first groove.

[0028] The T-shaped slider is adapted to slide in the first groove.

[0029] The second lead screw has its threads threaded through a T-shaped slider and can be rotatably threaded through the front and rear walls of the X-axis slide rail.

[0030] The first grip is fixed to the end through which the second lead screw passes;

[0031] The Y-axis slide rail is vertically fixed on the X-axis slide rail, and a second slide groove is opened on its top surface, which is slidably adapted to the lower part of the fixture.

[0032] The third lead screw has its threads threaded through the lower part of the clamp and can rotatably pass through the left and right walls of the Y-axis slide rail;

[0033] The second grip is fixed to the end of the third lead screw.

[0034] With this structure, the first and second grips are easy to control in the XY axis direction.

[0035] As a further improvement of this utility model, the clamp includes a T-shaped part, which is the lower part of the clamp. The T-shaped part is slidably adapted to the second slide groove and is passed through by a third lead screw in a threaded connection manner. Vertical plates are provided on both sides of the T-shaped part. Two spaced elongated holes are opened on one vertical plate, corresponding to the elongated holes on the opposite vertical plate. Positioning bolts are passed through the elongated holes and tightened by nuts. The positioning bolts are clamped on both sides of the female connector head and placed under the stepped surface of the female connector head shell.

[0036] With this structure, the positioning bolt moves along the elongated hole to accommodate female heads of different widths.

[0037] As a further improvement of this utility model, a limiting bolt is threaded through the vertical plate, and the limiting bolt abuts against the female head of the electrical connector.

[0038] With this structure, the limiting bolts press the female end of the electrical connector tightly to prevent it from slipping.

[0039] As a further improvement of this utility model, the lower part of the truncated cone-shaped pin cap is fixed to a ladder block, the ladder block is protruded from the pin, and one end of the ladder block is threaded with an anti-bending bolt.

[0040] With this structure, the inclined surface of the ladder block facilitates the measurement head's ascent along the inclined surface. The anti-bending bolts, pins, and ladder block form a gate-shaped structure, which helps prevent bending and protects the pins used for testing.

[0041] As a further improvement of this utility model, a wire groove is provided on the top surface of the T-shaped part.

[0042] With this structure, the cable trays facilitate the extension of communication cables.

[0043] This invention helps to detect the depth difference between the contact slots on the female connector to determine whether it meets the requirements of processing consistency. If the depth difference between the contact slots is too large, it can easily cause the pins to be affected by the shallow contact slots, resulting in insufficient insertion depth of the entire male connector, thus determining whether the electrical connector needs to be replaced.

[0059] Example 1

[0060] like Figures 1-4 As shown, a depth difference inspection device for the insertion of electrical connector pins into contact slots includes:

[0061] The depth dial indicator 1 includes a dial indicator 101, a bushing 102 at the lower part of the dial indicator 101, a measuring rod 103 disposed in the bushing 102, the measuring rod 103 extending out of the bushing 102, and a measuring head 104 disposed below the measuring rod 103.

[0062] Sleeve 2, which is inserted into bushing 102;

[0063] Tighten bolt 3, whose thread passes through sleeve 2 and abuts against bushing 102;

[0064] The bracket 4 has a first crossbar 401 fixed on the sleeve 2;

[0065] Base 5, which is fixed to the lower end of bracket 4;

[0066] The XY axis moving platform 6 is fixed on the base 5;

[0067] The clamp 7 is mounted on the XY axis moving platform 6 to hold the electrical connector female head 8;

[0068] Pin 9 is inserted into the contact slot 801 of the female connector 8, and is adapted to the contact slot 801, with its upper end extending out of the contact slot 801.

[0069] A frustum-shaped pin cap 10 is fixed to the upper end of pin 9, and is narrower at the top and wider at the bottom.

[0070] With this structure, a known pin 9 is inserted into the initial contact slot 801 to its deepest point. A frustum-shaped pin cap 10 is then placed against the bottom surface of the measuring head 104 of the depth dial indicator 1. The dial indicator is then set to 0. Here, an electronic depth dial indicator is used, and the measuring rod 103 is in a pre-compression state. The initial contact slot serves as the reference surface. Then, the pin 9 is pulled out and inserted into the second contact slot 801 to its deepest point. The pin 9 is moved using the XY-axis moving platform 6, and the frustum-shaped pin cap 10 is used to re-engage the measuring head 104. If the second contact slot 801 is shallow, the second insertion of the pin 9 will raise the measuring head 104, making the measured surface higher than the reference surface, resulting in a negative reading. Conversely, if the second contact slot 801 is deeper, the measuring rod 103 will descend, causing the dial indicator 101 to display a positive value. The above principle is to convert the bottom surface of the contact groove 801, which is inconvenient to measure, into the top surface of the frustum-shaped pin cap 10, which is easy to measure, so as to obtain the relative difference value. If some contact grooves 801 are too shallow, it will cause the pin insertion depth of other male connectors to be insufficient. In this case, the electrical connector can be replaced.

Vertical plates 702 are provided on both sides of the T-shaped part 701. Two spaced elongated holes 703 are opened on one vertical plate 702, corresponding to the elongated holes 703 on the opposite vertical plate 702. Positioning bolts 704 are passed through the elongated holes 703 and tightened by nuts. The positioning bolts 704 are clamped on both sides of the electrical connector female head 8 and placed under the stepped surface of the outer shell of the electrical connector female head 8.
