Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, in particular to an electronic connector housing structure. Background Art

[0002] Electronic connectors, also often called circuit connectors and electrical connectors, are important nodes in the entire system. Their transmission performance determines the transmission speed and quality of the entire network. The performance indicators of connectors are fast transmission speed, low loss and strong stability. Connectors are usually exposed to the external environment and must adapt to complex and harsh working environments. At the same time, they need to have the characteristics of corrosion resistance, moisture resistance, high temperature resistance and low temperature resistance.

[0003] An existing patent (publication number: CN219203581U) discloses an electronic connector housing structure, which tightly combines the first connector housing and the second connector housing by using a fastening sleeve and a fastening lock plate, and bends the conductive terminal through the housing cover to avoid the end of the conductive terminal occupying too much volume. The guide groove can correct the lead-out direction of the conductive terminal, thereby improving the connection precision and being suitable for situations where space is limited.

[0004] In the prior art, when the connector housing is in use, when the external environment is relatively humid, moisture contained in the air may enter the interior of the connector housing, which may cause damage to the internal components of the connector housing, thereby reducing the service life of the connector housing, affecting the normal use of the connector, and causing inconvenience in use. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide an electronic connector housing structure to solve the technical problem that the internal parts of the connector are damaged when the connector is in a humid environment.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an electronic connector housing structure, comprising a first connector housing, a second connector housing being movably sleeved below the first connector housing, a joint portion being fixedly mounted on the upper surface of the first connector housing, a sealing ring being fixedly mounted on the bottom end of the outer wall of the joint portion, and blocks being fixedly connected to the front and rear surfaces of the joint portion, a protective shell being fixedly connected to the upper surface of the second connector housing, an airbag being fixedly mounted on the top end of the inner wall of the protective shell, a piston cylinder being symmetrically arranged below the airbag and fixedly connected to the inner wall of the protective shell, a piston block being movably sleeved on the inner wall of the piston cylinder, a push rod being fixedly connected to one side surface of the piston block, an end of the piston cylinder away from the push rod being fixedly connected to a connecting tube fixedly connected to the airbag, an airbag groove matching the airbag being provided on the outer wall of the top end of the joint portion, and the protective shell being sleeved on the outer wall of the joint portion.

[0007] By adopting the above technical solution, the piston block is pushed by the push rod through the resistance block, and the gas inside the piston cylinder is transmitted to the inside of the airbag through the connecting tube through the piston block, thereby driving the airbag to expand. The first connector shell and the second connector shell are sealed by the airbag and the sealing ring to prevent external water vapor from entering between the first connector shell and the second connector shell.

[0008] Furthermore, positioning rods are symmetrically fixedly connected to the four corners of the upper surface of the first connector housing, and positioning holes matching the positioning rods are opened on the upper surface of the second connector housing.

[0009] By adopting the above technical solution, the first connector housing and the second connector housing are positioned for use by cooperating with the positioning holes through the positioning rods.

[0010] Furthermore, two groups of pinching plates are movably connected at both ends of the joint portion on the upper surface of the first connector housing, a spring is fixedly installed between the two groups of pinching plates, and an insertion rod is fixedly connected to the surface of the two groups of pinching plates away from the spring.

[0011] By adopting the above technical solution, by pinching the two sets of pinching plates, the pinching plates squeeze the springs, thereby facilitating the separation of the insertion rod from the slot, thereby facilitating the disassembly of the first connector housing and the second connector housing.

[0012] Furthermore, the upper surface of the second connector housing is fixedly connected to fixed blocks at both ends of the protective shell, and the inner walls at both ends of the fixed blocks are provided with insertion holes that match the insertion rod.

[0013] By adopting the above technical solution, the first connector housing and the second connector housing can be fixedly connected by inserting the insertion rod into the insertion hole on the fixing block.

[0014] Furthermore, the bottom ends of the two groups of pinching plates are fixedly connected with dovetail blocks, and the upper surface of the first connector housing is provided with two groups of dovetail grooves matching the dovetail blocks.

[0015] By adopting the above technical solution, the pinching plate can be limited in use by cooperating with the dovetail block and the dovetail groove, so that the pinching plate can be used to drive the insertion rod.

[0016] Furthermore, a conductive terminal is provided on the lower surface of the first connector housing, and a cover plate is movably mounted on the lower surface of the first connector housing, and the cover plate is in contact with the conductive terminal.

[0017] By adopting the above technical solution, the conductive terminal can be easily limited in position by using the cover plate, thereby preventing the conductive terminal from falling out.

[0018] To sum up, the present invention mainly has the following beneficial effects: the present invention achieves this by sleeve-mounting the first connector shell onto the second connector shell, and by using the downward pressure of the first connector shell to push the push rod through the block, thereby driving the airbag to expand, and the airbag cooperates with the sealing ring to seal the connection between the first connector shell and the second connector shell, thereby preventing external water vapor from entering the interior of the connector, and extending the service life of the connector to a certain extent.

[0028] The first connector housing 100 is sleeved on the outer wall of the second connector housing 120, and downward pressure is applied to the first connector housing 100. The piston block 1241 is pushed by the push block 115 in cooperation with the push rod 124. The gas inside the piston cylinder 123 is transmitted to the inside of the airbag 122 through the connecting tube 1231 through the piston block 1241, thereby driving the airbag 122 to expand. The first connector housing 100 and the second connector housing 120 are sealed by the airbag 122 in cooperation with the sealing ring.
