Description

Technical Field

[0001] This utility model relates to the field of connector design technology, specifically to a 14-pin rectangular signal connector socket. Background Technology

[0002] 14-pin connectors and sockets are widely used in various fields due to their high performance and versatility. For example, in industrial automation, they meet the high requirements of control systems for data transmission speed and stability; in network communication, their high bandwidth and low loss characteristics make them an ideal choice for network equipment. Furthermore, the aerospace industry's stringent requirements for connectors, such as high reliability, mechanical strength, and high-temperature resistance, are also met by 14-pin connectors and sockets. Simultaneously, in intelligent power management, their multi-pin design provides rich information support for the system.

[0003] Existing connectors and sockets typically feature a straight pin design, which is prone to fretting wear under insertion and extraction stress. Furthermore, the anti-misinsertion mechanism is simplistic, relying solely on a single protrusion limiting structure, with a insertion direction tolerance angle greater than ±5°. This results in an error rate as high as 3.2% during blind insertion operations. Utility Model Content

[0004] Therefore, the purpose of this application is to solve the technical problems of straight needle design being prone to fretting wear and having a single anti-misinsertion mechanism in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A 14-pin rectangular signal connector socket includes a support motherboard, an insert portion, and pins. The support motherboard and the insert portion are integrally formed. The insert portion is located on one side of the support motherboard and is used to mate with the male connector of the signal connector. The pins are L-shaped. One segment of the pin is perpendicular to the support motherboard and located inside the insert portion. The other segment of the pin is parallel to the support motherboard. Furthermore, the pin and one segment of the support motherboard are located on the side of the support motherboard away from the insert portion.

[0007] The support motherboard has a pin number indicator on the side pointing towards the embedded part;

[0008] The embedded part is provided with a number of guide keys. The guide keys are located on the inner sidewall of the connection between the embedded part and the supporting motherboard. The guide key group is asymmetrically arranged.

[0009] Preferably, there are four sets of guide keys, which are located on the four sides of the embedded part. At least two guide keys are provided on the long side of the embedded part, and the length of one of the guide keys on the long side of the embedded part is greater than that of the other guide keys.

[0010] Preferably, the two sets of guide keys located on the wide side of the embedded part are each provided with two keys, and the other two sets of guide keys are each provided with four keys.

[0011] Preferably, the height of the guide key is higher than the height of the pin portion inside the embedded part.

[0012] Preferably, the support main board is a rounded rectangular plate, the embedded part is a hollow column, the embedded part is perpendicular to the support main board, and the pin is disposed inside the embedded part.

[0013] Preferably, one segment of the pin is located inside the embedded part and is perpendicular to the support main board. The pin passes through the support main board and is bent at one end. The support main board is provided with a fixing block for fixing the bent part of the pin.

[0014] Preferably, there are 14 pins arranged in three rows on the inner side of the insert.

[0015] Preferably, the support motherboard is provided with waterproof adhesive, which is located on the side of the support motherboard facing the embedded part, and the waterproof adhesive is disposed around the edge of the support motherboard.

[0016] Preferably, the support main board is provided with four fixing threaded holes, which are located at the corners of the support main board and inside the rectangle formed by the waterproof adhesive.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] 1. The socket can be rigidly fixed by four symmetrically distributed threaded holes at the corners of the support motherboard, combined with the one-piece molded structure design. Compared with the traditional single-point fixing method, this four-corner distributed fixing can effectively disperse the insertion and extraction stress. Experimental data shows that its anti-displacement ability is improved by more than 60%, completely solving the problems of pin misalignment and interface deformation caused by misalignment when male and female connectors are plugged in.

[0019] 2. The system employs a dual protection approach of "stepped waterproof adhesive + structural sealing": 1-3mm thick waterproof tape forms a ring seal along the edge of the main support board, which can withstand immersion in water up to 1m deep according to IP67 standard testing. In addition, the embedded part is integrally molded with the main support board, eliminating the risk of water leakage at the joints of traditional split structures. At the same time, a secondary injection-molded sealing layer is set at the pin penetration point, forming a three-level waterproof barrier, which maintains excellent sealing performance even under vibration conditions.

[0020] 3. By using the asymmetric guide key group (a topological locking structure consisting of wide-side double guide keys (including differentiated length keys) and narrow-side four guide keys) inside the embedded part, combined with the pin number markings laser-etched on the motherboard surface, a dual guarantee of "mechanical error prevention + visual cues" is formed. Actual tests show that this design reduces the probability of incorrect insertion from the industry average of 3.2% to below 0.05%.

[0021] 4. By embedding the vertical section inside the part and cooperating with the support surface fixing block to form a double support structure, the L-shaped pin is fixed in segments. After 5000 insertion and removal tests, the contact resistance change rate is <2%. In addition, the three-row staggered pin layout (5+5+4) increases the signal transmission channel spacing by 40% and the crosstalk suppression ratio reaches -65dB@1GHz.

[0022] 5. The rounded rectangle support design of the main board allows the connectors to be installed with standard DIN41652 rails and custom panels.

[0023] Furthermore, the modular design of the guide key assembly supports quick model changeover, allowing for the creation of 12 / 16-core variants within the same mold framework. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please see Figure 1and Figure 2 A 14-pin rectangular signal connector socket includes a support motherboard 1, an insert portion 2, and pins 3. The support motherboard 1 and the insert portion 2 are integrally formed. The support motherboard 1 is a rounded rectangular plate. The insert portion 2 is located on one side of the support motherboard 1 and is used to mate with the male connector of the signal connector. The pins 3 are L-shaped. One section of the pins 3 is perpendicular to the support motherboard 1 and located inside the insert portion 2. The other section of the pins 3 is parallel to the support motherboard 1. Furthermore, the pins 3 and one section of the support motherboard 1 are located on the side of the support motherboard 1 opposite to the insert portion 2.

[0030] Please see Figure 1 and Figure 2 The support main board 1 is arranged in the shape of a rounded rectangle. The support main board 1 is provided with a fixing threaded hole 11 and a waterproof adhesive 12. The waterproof adhesive 12 is located on the side of the support main board 1 facing the embedded part 2. The waterproof adhesive 12 is arranged around the edge of the support main board 1. In one embodiment, the thickness of the waterproof adhesive 12 is set to 1-3mm.

[0031] Four fixing threaded holes 11 are provided, and the four fixing threaded holes 11 are respectively located at the corners of the support motherboard 1, and the fixing threaded holes 11 are located on the inner side of the rectangle formed by the waterproof adhesive 12. The fixing threaded holes 11 facilitate the fixing of the support motherboard 1, thereby preventing the male and female heads from being misaligned and causing damage to the connector when the male head is inserted.

[0032] Please see Figure 1 and Figure 2 The embedded part 2 is a hollow cylindrical shape, perpendicular to the supporting main board 1. The pin 3 is disposed inside the embedded part 2. In one embodiment, the embedded part 2 is provided with a plurality of guide keys 21. The guide keys 21 are located on the inner sidewall of the connection between the embedded part 2 and the supporting main board 1. Specifically, there are four sets of guide keys 21, located on the four sides of the embedded part 2. Two sets of guide keys 21 on the wide side of the embedded part 2 each have two guide keys, and the other two sets each have four guide keys. One of the guide keys 21 on the long side of the embedded part 2 is longer than the others. By limiting the length, the reverse insertion can be avoided during the male-female connector mating process. In one embodiment, please refer to... Figure 3 The height of the guide key 21 is higher than the height of the pin 3 inside the embedded part 2.

[0033] Please see Figure 1 and Figure 2 One section of the pin 3 is located inside the embedding part 2 and is perpendicular to the supporting main board 1. The pin 3, perpendicular to the supporting main board 1, passes through the supporting main board 1 and is bent. A fixing block 13 is provided on the supporting main board 1 to fix the bent portion of the pin 3, preventing bending and deformation. There are 14 pins 3 arranged in three rows inside the embedding part 2.

[0034] Please see Figure 1 and Figure 2 The support motherboard 1 has a pin number identifier 22 on the side pointing to the embedded part 2, which is used to identify the pins 3 and further avoid errors in the insertion process.

[0035] The 14-pin rectangular signal connector socket provided in this application achieves breakthroughs in key indicators such as connection reliability, environmental adaptability, and operational safety through systematic structural innovation. It is particularly suitable for high-frequency signal transmission scenarios in harsh environments such as rail transit and industrial robots. The tested service life reaches 100,000 insertion and removal cycles, which is more than 3 times that of traditional products.
