Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a solder plate fixed waterproof electrical connector. Background Technology

[0002] Electrical connectors are core components used to achieve circuit conduction and signal transmission. In use, plug connectors and socket connectors are paired and interlocked. Socket connectors are often used to fix the device to the enclosure. Socket connectors specifically include a housing, insulator, and contacts. One end of the contact is used to connect with the socket connector and the other end is used to connect with conductive parts (such as PCB boards) inside the enclosure. The housing is used to fix the device to the enclosure, or the housing is directly formed as part of the enclosure.

[0003] Existing solder plate fixed connectors use glue for waterproofing, which leads to glue overflow and long curing time, affecting processing efficiency. In addition, some connectors are prone to instability during assembly, with pins easily becoming unstable and wobbly.

[0004] Therefore, this solution provides a waterproof electrical connector with a solder plate fixed by combining signal and power contacts. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof electrical connector with a fixed solder plate to solve the problems mentioned above.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A type of waterproof electrical connector with a fixed solder plate includes a plastic shell, wherein a plurality of power pins are arranged in a rectangular array on the plastic shell and a plurality of signal holes are arranged on the plastic shell and between the plurality of power pins.

[0008] The power pin of the welded plate fixed waterproof electrical connector has a pin sealing groove, and an O-ring is provided inside the pin sealing groove. The power pin has an outer pin step and an inner pin step on both sides of the O-ring.

[0009] The plastic shell type of welded plate fixed waterproof electrical connector has a plurality of pin mounting holes arranged in a rectangular array. The end of the pin mounting hole located outside the plastic shell type of welded plate fixed waterproof electrical connector has an external pin limiter. The end of the pin mounting hole located inside the plastic shell type of welded plate fixed waterproof electrical connector has an internal pin limiter.

[0010] The existing single-ended waterproof connector's adhesive waterproofing structure has been optimized by eliminating the plastic shell and sealant groove structure and replacing them with a compact O-ring sealing structure.

[0011] The design includes a housing sealing ring structure, allowing customers to choose whether or not to use the housing sealing ring based on the specific product usage environment; this is equivalent to adding some functions to the existing conventional solder plate fixed connector.

[0012] The connector features a compact overall structure and employs a mixed signal and power contact transmission mode to meet diverse customer transmission requirements. The contacts are secured using a limiting and interference fit structure, ensuring a secure and non-loose assembly. Furthermore, the connector is designed with both single-end waterproof and installation waterproof options to meet customer protection requirements.

[0013] The beneficial effects of this utility model are:

[0014] In this solution, an O-ring seal and a needle insulating cap are installed on the power board pin to form a board pin assembly. Then, the board pin assembly is pushed into the board pin mounting hole on the plastic shell. The signal board hole is pressed into the plastic shell using a jig and a hand press. The enclosure sealing ring is directly installed into the enclosure sealing groove outside the plastic shell. The overall assembly process is simple and clear, requires few tools, has a short assembly time, and is convenient to assemble. The power board pin uses an O-ring seal to achieve single-end waterproofing, which avoids glue spillage compared to glue sealing. The assembly is completed and the product can be shipped immediately. At the same time, it saves the waiting time for the glue to solidify, improves production efficiency, and the enclosure sealing ring outside the plastic shell further provides a connection and sealing effect during use.

[0015] The connector is compact and practical, achieving waterproofing with less installation space and higher overall stability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 As shown, this utility model is a solder plate fixed waterproof electrical connector, including a plastic shell 1. The plastic shell 1 has a plurality of power pins 2 arranged in a rectangular array on its upper surface. The plastic shell 1 also has a plurality of signal pin holes 3 arranged on its upper surface and between the power pins 2. The plastic shell 1 serves to install, fix and protect the contact parts, fix it to the client equipment, and install waterproof parts and cooperate with other accessories to achieve single-end waterproofing and waterproof installation.

[0027] First, a pin sealing groove 20 is provided on the power pin 2, and an O-ring 22 is provided in the pin sealing groove 20. An outer step 24 and an inner step 25 are respectively provided on both sides of the O-ring 22 on the power pin 2. An insulating cap mounting hole 23 is provided at one end of the power pin 2 inside the plastic shell 1. A pin insulating cap 21 is provided in the insulating cap mounting hole 23. The pin insulating cap 21 is installed on the top of the mating end of the power pin 2 to prevent direct contact between the live power pin 2 and the human hand. The O-ring 22 is installed on the power pin 2. Finally, after the power pin 2 is installed into the plastic shell 1, it is squeezed by the power pin 2 and the plastic shell 1 to waterproof and isolate the wiring end and the signal end of the connector. It should be noted that the end of the power pin 2 inserted into the plastic shell 1 is the signal end and the other end is the wiring end.

[0028] The plastic shell 1 has a plurality of plate pin mounting holes 12 arranged in a rectangular array. One end of the plate pin mounting hole 12 located outside the plastic shell 1 is provided with an outer plate pin limiter 121, and the other end of the plate pin mounting hole 12 located inside the plastic shell 1 is provided with an inner plate pin limiter 120.

[0029] The power board pin 2 is inserted into the pin mounting hole 12 and installed in the plastic shell 1 through a limiting structure for high current transmission. When the insertion is completed, the outer step 24 of the pin is located within the outer limit 121 of the pin, and the inner step 25 of the pin is located at the end of the inner limit 120 of the pin. The power board pin 2 is in the limiting state. At this time, the power board pin 2 is fixed. At the same time, the O-ring 22 on the power board pin 2 forms a sealing effect with the inner wall of the pin mounting hole 12, which can effectively prevent water from flowing from the terminal to the plug-in terminal. Similarly, it can also prevent water from flowing from the plug-in terminal to the terminal, achieving a single-end sealing effect.

[0030] Secondly, the plastic shell 1 has several board mounting holes 13 located between several power board pins 2; the signal board hole 3 is inserted into the board mounting hole 13, and the board mounting hole 13 has a board hole limit 130 inside; the outside of the signal board hole 3 is provided with an interference barb 31, which is snapped into the board hole limit 130, ensuring that after the signal board hole 3 is inserted into the plastic shell 1, it is effectively fixed in the plastic shell 1 under the action of the interference barb 31. The signal board hole 3 is pressed into the plastic shell 1 by interference fit for small current signal transmission.

[0031] Finally, a housing sealing groove 10 is opened on the outside of the plastic shell 1, and a housing sealing ring 11 is set in the housing sealing groove 10. The housing sealing ring 11 is installed on the outside of the plastic shell 1. Its function depends on whether the customer needs the housing to be waterproof. If the customer needs it, the installation size of the housing can be made according to the connector shape specifications on the customer's side.

[0032] In this solution, an O-ring 22 and a needle insulating cap 21 are installed on the power board needle 2 to form a board needle assembly. Then, the board needle assembly is pushed into the board needle mounting hole 12 on the plastic shell 1. The signal board hole 3 is pressed into the plastic shell 1 using a jig and a hand press. The housing sealing ring 11 is directly installed into the housing sealing groove 10 outside the plastic shell 1. The overall assembly process is simple and clear, requires few tools, has a short assembly time, and is convenient to assemble. The power board needle 2 uses an O-ring 22 to achieve single-end waterproofing. Compared with the glue sealing method, it avoids glue spillage. The assembly is completed and the product can be shipped immediately. At the same time, it saves the waiting time for the glue to solidify and improves production efficiency. Meanwhile, the housing sealing ring 11 outside the plastic shell 1 further plays a connecting and sealing role during use.

[0033] The connector is compact and practical, achieving waterproofing with less installation space and higher overall stability.
