Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a low-cost connector socket and connector. Background Technology

[0002] Connectors and sockets are used for electrical connections and the transmission of electrical signals; they are fundamental components of circuit systems. For example... Figure 1 As shown, a conventional connector socket includes a housing 101, two terminals 103, and a tail cover 102. The two terminals 103 are mounted on the housing 101, the tail cover 102 has a receiving cavity, and the end of the tail cover 102 is provided with an injection hole 104 and two through holes 105.

[0003] The assembly process of the connector socket is as follows: First, the tail cap 102 is snapped onto the housing 101, and the two terminals 103 are located in the receiving cavity and protrude from the two through holes 105 respectively. Then, glue is injected into the receiving cavity through the glue injection hole 104 until the receiving cavity is full. After the glue cools and solidifies, it forms a glue for fixing the two terminals 103.

[0004] The existing connector socket requires filling the entire receiving cavity of the tail cover 102 with glue, which consumes a large amount of glue and increases the manufacturing cost of the connector socket. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a connector socket, the detailed technical solution of which is as follows:

[0006] A low-cost connector socket includes a housing, a first terminal block, a second terminal block, and a rear cover, wherein:

[0007] The tail end of the housing is provided with a ring of snap-fit ​​grooves, and the housing is provided with a first mounting hole and a second mounting hole.

[0008] The first end of the first terminal is inserted into the first mounting hole, and the first end of the second terminal is inserted into the second mounting hole.

[0009] The rear end of the back cover is provided with a snap-fit ​​part that matches the snap-fit ​​groove. The back cover is provided with a first insertion hole and a second insertion hole. The diameter of the first insertion hole is larger than the diameter of the first terminal block, and the diameter of the second insertion hole is larger than the diameter of the second terminal block.

[0010] The back cover is snapped into the snap-fit ​​groove via the snap-fit ​​part. The first terminal is inserted into the first plug hole, and the second end of the first terminal protrudes out of the first plug hole. The second terminal is inserted into the second plug hole, and the second end of the second terminal protrudes out of the second plug hole.

[0011] Both the first and second insertion holes are filled with colloid.

[0012] The low-cost connector socket provided by this utility model has a first insertion hole and a second insertion hole inside its back cover. After the back cover is snapped onto the housing, the first terminal passes through the first insertion hole, and the second terminal passes through the second insertion hole. Therefore, only glue needs to be filled into the first and second insertion holes to encapsulate and fix the first and second terminals, thereby reducing the amount of glue used and effectively reducing the manufacturing cost of the connector socket.

[0013] In some embodiments, the surfaces of the first terminal and the second terminal are provided with an anti-oxidation coating.

[0014] By applying an anti-oxidation coating to the surfaces of the first and second terminals, oxidation and corrosion of the first and second terminals in humid environments can be prevented, thereby extending the service life of the connector socket.

[0015] In some embodiments, the outer contour of the back cover is in the shape of a three-step structure, with the dimensions of the three steps decreasing sequentially in the direction away from the housing.

[0016] The three-tiered steps create a gradually transitioning support structure. The steps closer to the housing are larger, providing a wider support surface and significantly improving the local rigidity and torsional resistance of the area where the back cover connects to the housing. This effectively prevents the back cover from deforming or breaking when the connector is plugged in or removed, or when subjected to lateral forces, protecting the internal terminals and adhesive seals.

[0017] In some embodiments, the housing includes a mounting plate, a first mounting cylinder, a second mounting cylinder, and a mating sleeve, wherein: the first mounting cylinder and the second mounting cylinder are arranged side by side on the mounting plate, the inner hole of the first mounting cylinder forms a first mounting hole, and the inner hole of the second mounting cylinder forms a second mounting hole; the mating sleeve is disposed on the mounting plate and surrounds the outer side of the first mounting cylinder and the second mounting cylinder; the mounting plate is provided with mounting screw holes.

[0018] The mating sleeve surrounds the outer side of the double mounting cylinder, forming a protective barrier to protect the internal terminal roots from external impacts. Furthermore, the connector plug can mate with the connector socket via the mating sleeve. Screw holes on the mounting plate allow the connector socket to be screwed securely to the target device.

[0019] In some embodiments, a locking structure is provided on the outer side of the mating sleeve.

[0020] When the connector plug mates with the connector socket via the mating sleeve, the locking structure locks the connector plug and connector socket in place, preventing the connector plug from falling off.

[0021] In some embodiments, the tail end of the housing is further provided with a first locking ring and a second locking ring, wherein the first locking ring is used to lock the first terminal block in the first mounting hole, and the second locking ring is used to lock the second terminal block in the second mounting hole.

[0022] By setting a first locking ring and a second locking ring at the tail end of the housing, the first terminal block and the second terminal block are locked, preventing them from becoming loose.

[0023] This utility model also provides a connector, which includes a connector plug and a low-cost connector socket as described in any of the above. Attached Figure Description

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] As described in the background section, existing connector sockets require glue to fill the entire receiving cavity of the tail cap, which consumes a large amount of glue and increases the manufacturing cost of the connector socket.

[0038] Therefore, this utility model provides a low-cost connector socket that can reduce the amount of glue used, thereby effectively reducing the manufacturing cost of the connector socket.

[0039] like Figures 2 to 5 As shown, the low-cost connector socket provided by this utility model includes a housing 1, a first terminal block 2, a second terminal block 3, and a rear cover 4. The housing 1 has a retaining groove 11 at its tail end, and a first mounting hole 12 and a second mounting hole 13 are provided inside the housing 1. The first end of the first terminal block 2 is inserted into the first mounting hole 12, and the first end of the second terminal block 3 is inserted into the second mounting hole 13.

[0040] The rear cover 4 has a snap-fit ​​part 41 at its tail end, which matches the snap-fit ​​groove 11. The rear cover 4 has a first insertion hole 42 and a second insertion hole 43 inside. The diameter of the first insertion hole 42 is larger than the diameter of the first terminal 2, and the diameter of the second insertion hole 43 is larger than the diameter of the second terminal 3.

[0041] The back cover 4 is snapped into the snap-fit ​​groove 11 via the snap-fit ​​part 41. The first terminal 2 passes through the first insertion hole 42, and the second end of the first terminal 2 extends outward from the first insertion hole 42. The second terminal 3 passes through the second insertion hole 43, and the second end of the second terminal 3 extends outward from the second insertion hole 43.

[0042] Both the first insertion hole 42 and the second insertion hole 43 are filled with colloid.

[0043] The low-cost connector socket provided by this utility model has a first insertion hole 42 and a second insertion hole 43 provided in the back cover 4. After the back cover 4 is snapped onto the housing 1, the first terminal 2 passes through the first insertion hole 42 and the second terminal 3 passes through the second insertion hole 43. Therefore, only glue needs to be potted into the first insertion hole 42 and the second insertion hole 43 to encapsulate and fix the first terminal 2 and the second terminal, thereby reducing the amount of glue used and effectively reducing the manufacturing cost of the connector socket.

[0044] Optionally, the surfaces of the first terminal 2 and the second terminal 3 are provided with an anti-oxidation coating. By providing an anti-oxidation coating on the surfaces of the first terminal 2 and the second terminal 3, oxidation and corrosion of the first terminal 2 and the second terminal 3 in humid environments can be prevented, thereby extending the service life of the connector socket.

[0045] like Figure 3 As shown, optionally, the outer contour of the back cover 4 is a three-step shape, with the dimensions of the three steps decreasing sequentially in the direction away from the housing 1. The three steps form a gradually transitioning support structure. The steps closer to the housing 1 are larger, providing a wider support surface and significantly improving the local rigidity and torsional resistance of the connection area between the back cover 4 and the housing 1. This effectively prevents the back cover 4 from deforming or breaking when the connector is plugged in or removed, or when subjected to lateral forces, protecting the internal wiring terminals and adhesive seals.

[0046] Optionally, the housing 1 includes a mounting plate 14, a first mounting cylinder 15, a second mounting cylinder 16, and a mating sleeve 17, wherein: the first mounting cylinder 15 and the second mounting cylinder 16 are arranged side by side on the mounting plate 14, the inner hole of the first mounting cylinder 15 forms a first mounting hole 12, and the inner hole of the second mounting cylinder 16 forms a second mounting hole 13; the mating sleeve 17 is disposed on the mounting plate 14 and surrounds the outside of the first mounting cylinder 15 and the second mounting cylinder 16; the mounting plate 14 is provided with mounting screw holes 18.

[0047] The mating sleeve 17 forms a protective barrier around the outside of the double mounting cylinder, protecting the roots of the first terminal 2 and the second terminal 3 from external impacts. Furthermore, the connector plug can mate with the connector socket via the mating sleeve 17. And by providing mounting screw holes 18 on the mounting plate 14, the connector socket of this invention can be screwed and fixed to the target device.

[0048] Optionally, a locking structure 19 is provided on the outer side of the mating sleeve 17. When the connector plug mates with the connector socket through the mating sleeve 17, the locking structure 19 can lock the connector plug and the connector socket together, preventing the connector plug from falling off.

[0049] like Figure 3As shown, optionally, the tail end of the housing 1 is also provided with a first locking ring 110 and a second locking ring 111, wherein the first locking ring 110 is used to lock the first terminal 2 in the first mounting hole 12, and the second locking ring 111 is used to lock the second terminal 3 in the second mounting hole 13.

[0050] By setting a first locking ring 110 and a second locking ring 111 at the tail end of the housing 1, the first terminal 2 and the second terminal 3 are locked, preventing the first terminal 2 and the second terminal 3 from becoming loose.

[0051] This utility model also provides a connector, which includes a connector plug and a low-cost connector socket provided in any of the above embodiments.

[0052] The present invention has been described in sufficient detail above, and is therefore quite specific. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the present invention should fall within the protection scope of the present invention.
