[0037] See Figures 1 to 4 An embodiment of the present application provides a connector housing structure 100, comprising a first housing 1, a second housing 2, a first connecting portion 12, a second connecting portion 22 and an end cover 3, wherein:

[0038] The first housing 1 and the second housing 2 are snap-fitted and together enclose a mounting cavity. The mounting cavity 1a has an open end and a threading end. One end of the first connecting portion 12 is connected to the first housing 1, and the other end extends away from the threading end. One end of the second connecting portion 22 is connected to the second housing 2, and the other end extends away from the threading end. The end cap 3 is mounted on the first housing 1 and the second housing 2 and covers the open end. The end cap 3 is provided with a third connecting portion 321 and a fourth connecting portion 322. The first connecting portion 12 snaps into engagement with the third connecting portion 321, and the second connecting portion 22 snaps into engagement with the fourth connecting portion 322.

[0039] In the above-described connector housing structure 100, due to the snap-fitting between the first housing 1 and the second housing, the snap-fitting between the first connecting portion 12 and the third connecting portion 321, and the snap-fitting between the second connecting portion 22 and the fourth connecting portion 322, when assembling the connector housing structure 100, simply snap-fitting the first housing 1 and the second housing 2 can quickly and reliably complete the connection between the first housing 1 and the second housing 2. Furthermore, snap-fitting the first connecting portion 12 and the third connecting portion 321, and the second connecting portion 22 and the fourth connecting portion 322, allows the end cap 3 to be quickly and reliably fitted over the first housing 1 and the second housing 2, completing the rapid assembly of the connector housing structure 100. Therefore, the assembly operation of the connector housing structure 100 is simple, significantly reducing assembly processing time and effectively improving assembly efficiency. Furthermore, because the connector housing structure 100 is assembled through snap-fitting between the housings, it can also reduce production costs compared to connector housings secured with screws.

[0040] Specifically, when the connector housing structure 100 is connected to a connection socket, the end cover 3 can be inserted into the connection socket.

[0041] In one embodiment, combined Figure 2 As shown, one of the first housing 1 and the second housing 2 is provided with a slot, and the other is provided with a buckle that engages with the slot. Thus, the first housing 1 and the second housing 2 can be quickly and reliably connected through the engagement between the buckle and the slot, thereby effectively improving the assembly efficiency of the connector housing structure 100.

[0042] Optionally, the number of the buckles and the number of the slots are both at least two, at least two buckles are arranged at intervals, and the buckles and the slots are snap-fitted in a one-to-one correspondence.

[0043] Indicative, such as Figure 2 As shown, a buckle is protruding from the inner wall of the first housing 1, and a mating portion 21 is protruding from the edge of the second housing 2. The mating portion 21 has a slot that mates with the buckle. Thus, when the first and second housings 1 and 2 are connected, the buckle can be snapped into the slot of the mating portion 21 under the action of an external force, thereby fixing the first and second housings 1 and 2 relative to each other.

[0044] Specifically, when the first housing 1 and the second housing 2 are injection-molded parts, the first housing 1 and the latch or slot provided on the first housing 1 are integrally formed, and the second housing 2 and the slot or latch provided on the second housing 2 are integrally formed. This not only effectively reduces the production costs of the first housing 1 and the second housing 2, but also effectively ensures the reliability and stability of the connection between the first housing 1 and the second housing 2.

[0045] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the end cap 3 includes a panel 31 and an end plate 32. The panel 31 is formed with a through hole. The panel 31 is mounted on one end of the first shell 1 and the second shell 2. The end plate 32 is positioned within the through hole and covers the open end. In this way, the end cap 3 can be securely mounted on the first shell 1 and the second shell 2, so that the first connection portion 12 connected to the first shell 1 can be easily connected to the third connection portion 321 in the end cap 3, and the second connection portion 22 connected to the second shell 2 can be easily connected to the fourth connection portion 322 in the end cap 3, thereby ensuring that the end plate 32 can securely cover the open end.

[0046] Optionally, the third connection portion 321 and the fourth connection portion 322 can be provided on the enclosure 31 or on the end plate 32. For example, when the first connection portion 12 and the second connection portion 22 are hooks protruding from the opening edge of the installation cavity 1a, the third connection portion 321 and the fourth connection portion 322 can both be hook grooves provided on the inner wall of the enclosure 31, or can be hook grooves provided on the surface of the end plate 32 facing the installation cavity 1a.

[0047] Furthermore, in one embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, one end of the third connection portion 321 and one end of the fourth connection portion 322 are both connected to the end plate 32, and the other ends of the third connection portion 321 and the other ends of the fourth connection portion 322 extend toward the side where the mounting cavity 1a is located. The end of the first connection portion 12 close to the threading end is connected to the inner wall of the first shell 1, and the other end of the first connection portion 12 is snap-fitted with the third connection portion 321. The end of the second connection portion 22 close to the threading end is connected to the inner wall of the second shell 2, and the other end of the second connection portion 22 is snap-fitted with the fourth connection portion 322. In this way, during assembly, the first connection portion and the second connection portion will not abut the inner wall of the enclosure 31, so that the enclosure 31 can be more conveniently mounted on the first shell 1 and the second shell 2. In addition, since the first connecting portion 12, the second connecting portion 22, the third connecting portion 321 and the fourth connecting portion 322 are all cantilever structures, the free end of each connecting portion has a certain elastic margin, so that each connecting portion can be well connected to its corresponding connecting portion to quickly complete the assembly of the connector housing structure 100.

[0048] Optional, such as Figure 3As shown, the end of the first connecting portion 12 facing away from the threading end can be passed through the opening of the mounting cavity 1a and out of the mounting cavity 1a and connected to the third connecting portion 321. The end of the second connecting portion 22 facing away from the threading end can be passed through the opening of the mounting cavity 1a and out of the mounting cavity 1a and connected to the fourth connecting portion 322. This helps ensure the reliability of the connection between the first connecting portion 12 and the third connecting portion 321, and between the second connecting portion 22 and the fourth connecting portion 322.

[0049] Optionally, the number of the first connection parts 12, the number of the second connection parts 22, the number of the third connection parts 321, and the number of the fourth connection parts 322 can be set as needed, for example, one, two, three, or more. The number of the first connection parts 12 can be the same as or different from the number of the second connection parts 22. For example, the number of the first connection parts 12 can be one, and the number of the second connection parts 22 can be two.

[0050] Furthermore, in one embodiment, Figure 3 As shown, the number of first connecting portions 12 and the number of third connecting portions 321 are both at least two, and the at least two first connecting portions 12 are spaced apart. The first connecting portions 12 and the third connecting portions 321 are snap-fitted in a one-to-one correspondence. This not only effectively ensures the assembly efficiency of the first housing 1 and the end cover 3, but also helps to improve the reliability of the connection between the first housing 1 and the end cover 3.

[0051] Furthermore, in one embodiment, Figure 3 As shown, the number of the second connection parts 22 and the number of the fourth connection parts 322 are both at least two, and the at least two second connection parts 22 are spaced apart. The second connection parts 22 and the fourth connection parts 322 are engaged with each other in a one-to-one correspondence. This not only effectively ensures the assembly efficiency of the second housing 2 and the end cover 3, but also helps to improve the reliability of the connection between the second housing 2 and the end cover 3.

[0052] Optional, such as Figure 3 As shown, the number of first connecting parts 12, the number of second connecting parts 22, the number of third connecting parts 321, and the number of fourth connecting parts 322 are all two. The two first connecting parts 12 are arranged opposite each other, the two second connecting parts 22 are arranged opposite each other, the second connecting parts 22 and the first connecting parts 12 are arranged opposite each other in a one-to-one correspondence, and the third connecting parts 321 and the fourth connecting parts 322 are arranged in a one-to-one correspondence. In this way, the third connecting parts 321 and the fourth connecting parts 322 can be integrally formed, which helps to simplify the structure of the end cap 3. At the same time, it also helps to ensure the reliability and stability of the connection of the connector housing structure 100.

[0053] Optionally, both the end of the first connecting portion 12 facing away from the threading end and the end of the second connecting portion 22 facing away from the threading end are provided with undercuts, and both the end of the third connecting portion 321 facing away from the end plate 32 and the end of the fourth connecting portion 322 facing away from the end plate 32 are provided with grooves, with each undercut engaging with a corresponding groove. Thus, when assembling the connector housing structure 100, the undercuts can be engaged with the corresponding grooves, allowing the first connecting portion 12 to be securely connected to the third connecting portion 321, and the second connecting portion 22 to be securely connected to the fourth connecting portion 322, thereby allowing the end cap 3 to be securely mounted on the first housing 1 and the second housing 2.

[0054] In one embodiment, combined Figure 2 and Figure 3 As shown, first guide portions 11 are provided on the outer surfaces of both the first and second housings 1 and 2, and at least two second guide portions 311 are spaced apart on the inner wall of the end cap 3. The first guide portions 11 and the second guide portions 311 are pluggably mated in a one-to-one correspondence. This ensures the precise connection between the end cap 3 and the first and second housings 1 and 2, utilizing the coordination between the first and second guide portions 11 and 311, thereby improving the assembly efficiency of the connector housing structure 100.

[0055] Optionally, one of the first guide portion 11 and the second guide portion 311 is a guide boss, and the other is a guide groove. Figure 2 and Figure 3 As shown, the first guide portion 11 is a guide groove, and the second guide portion 311 is a guide ridge.

[0056] Specifically, such as Figure 2 As shown, the second guide portion 311 is provided on the inner wall of the enclosure 31, and the extension direction of the second guide portion 311 is the same as the extension direction of the third connecting portion 321 and the fourth connecting portion 322. In this way, the cooperation between the first guide portion 11 and the second guide portion 311 also plays a positioning and guiding role, thereby ensuring that the first connecting portion 12 and the third connecting portion 321 can be reliably connected to each other. Ensure that the second connecting portion 22 and the fourth connecting portion 322 can be reliably connected to each other.

[0057] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the outer surface of the end cap 3 is provided with a third guide portion 312, which is used to engage with the connecting socket. Thus, the third guide portion 312 on the end cap 3 can be used to cooperate with the connecting socket in the host to ensure that the connector housing structure 100 is correctly inserted into the connecting socket, thereby ensuring the accuracy and reliability of the connection between the two.

[0058] Optionally, the third guide portion 312 may be a guide boss or a guide groove.

[0059] Specifically, such as Figure 1 As shown, the third guide portion 312 is provided on the outer surface of the enclosure 31, and the extension direction of the third guide portion 312 is the same as the plugging and unplugging direction when the connector housing structure 100 is plugged in and out of the connecting socket. In this way, the cooperation between the third guide portion 312 and the connecting socket can also serve as a plug-in guide.

[0060] See Figures 1 to 4 An embodiment of the present application further provides an endoscope system, comprising the connector housing structure 100 in any of the above embodiments.

[0061] In the above-mentioned endoscope system, due to the snap-fitting of the first housing 1 and the second housing, the snap-fitting of the first connecting portion 12 and the third connecting portion 321, and the snap-fitting of the second connecting portion 22 and the fourth connecting portion 322 of the connector housing structure 100, when assembling the connector housing structure 100, only the snap-fitting of the first housing 1 and the second housing 2 is required to quickly and reliably complete the connection between the first housing 1 and the second housing 2. Furthermore, by snapping the first connecting portion 12 and the third connecting portion 321, and the snap-fitting of the second connecting portion 22 and the fourth connecting portion 322, the end cap 3 can be quickly and reliably fixedly mounted on the first housing 1 and the second housing 2, completing the rapid assembly of the connector housing structure 100. Therefore, the endoscope system has the characteristics of simple and convenient assembly and high assembly efficiency.

[0062] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments merely illustrate several implementation methods of the present application.
