For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] In the description of the present application, the terms "comprising", "containing" or any other variant thereof are intended to cover a non-exclusive inclusion, such that an item or device that comprises a list of elements does not only include those elements, but can also include other elements not expressly listed, or also include elements inherent in such item or device. Without more limitations, the element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the item or device comprising the element.

[0031] In the prior art, the terminal is usually inserted into the hollow groove opened on the surface of the terminal shell, so as to facilitate the sleeving of the terminal shell on the outside of the terminal. The hollow groove lacks a plugging device, which can cause the terminal to easily slide out of the hollow groove, the terminal to separate from the terminal shell (PIN withdrawal), and further cause the terminal connection to be interrupted, affecting the quality of signal transmission.

[0032] In view of the technical problem that the terminal is easily separated from the terminal shell in the prior art, the present application provides a terminal shell, a terminal assembly and a connector to overcome the above problems.

[0033] The terminal shell, the terminal assembly and the connector provided by the present application will be described below in conjunction with the accompanying drawings.

[0034] In some embodiments, referring to Figures 1 to 3 , the present application provides a terminal shell 1, which has a first part 10 and a second part 11 connected; the first part 10 and the second part 11 form an L-shaped structure. The first part 10 is provided with a first accommodating hole 100, which penetrates the first part 10 along the axial direction a of the first part 10; the second part 11 is provided with a second accommodating hole 110, which penetrates the second part 11 along the axial direction b of the second part 11. The first accommodating hole 100 and the second accommodating hole 110 are in communication.

[0035] The first part 10 has a first end face 101 perpendicular to the axial direction b of the second part 11, and a second end face 102 perpendicular to the first end face 101; the first end face 101 is provided with a hollow groove 103, which communicates the first accommodating hole 100 with the outside of the terminal shell 1; one end of the hollow groove 103 penetrates to the second end face 102, and the other end of the hollow groove 103 penetrates to the second accommodating hole 110; the second end face 102 is an end face not in contact with the outer surface of the second part 11.

[0036] The first end face 101 is provided with an even number of hot melt bodies 12; the even number of hot melt bodies 12 are arranged at the edges of the hollow groove 103 and symmetrically distributed on both sides of the hollow groove 103.

[0037] In some embodiments, under the condition of heating and melting, the two hot melts 12 distributed symmetrically are subjected to extrusion in the direction of the hollow groove 103, so that the two hot melts 12 are deformed in the direction of the hollow groove 103 and contact each other to form an integrated structure, covering part of the hollow groove 103 and achieving plugging of the hollow groove 103. Based on this embodiment, the hot melts 12 are symmetrically arranged along the hollow groove 103, which is conducive to the contact of the hot melts 12 to form an integrated structure, achieving better plugging effect.

[0038] In some embodiments, referring to Figure 4 , the hot melt 12 has a third end face 120 and a fourth end face 121 arranged opposite to each other; the area of the third end face 120 is smaller than that of the fourth end face 121; and the fourth end face 121 is connected with the first end face 101. The hot melt 12 can have a prism structure, in which a bottom face with a larger area is connected with the first end face 101. Based on this embodiment, the bottom face of the integrated structure formed by the two hot melts 12 after being subjected to extrusion under the condition of heating and melting will not exceed the first end face, thus not affecting the subsequent assembly of the terminal assembly and the connector housing to form a connector.

[0039] In some embodiments, the hot melt 12 is integrally formed with the terminal housing 1.

[0040] In some embodiments, referring to Figure 5 and Figure 6 , the application provides a terminal housing 1 having a first part 10 and a second part 11 connected with each other; the first part 10 and the second part 11 form an L-shaped structure. The first part 10 is provided with a first accommodating hole 100 penetrating through the first part 10 along the axial direction a of the first part 10. The second part 11 is provided with a second accommodating hole 110 penetrating through the second part 11 along the axial direction b of the second part 11. The first accommodating hole 100 and the second accommodating hole 110 are connected in communication.

[0041] The first part 10 has a first end face 101 perpendicular to the axial direction b of the second part 11, and a second end face 102 perpendicular to the first end face 101; the first end face 101 is provided with a hollow groove 103, which is in communication with the first accommodating hole 100 and the outside of the terminal housing 1; one end of the hollow groove 103 penetrates to the second end face 102, and the other end of the hollow groove 103 penetrates to the second accommodating hole 110.

[0042] The first end face 101 is provided with at least one hot melt 12, which extends to the hollow groove 103 to plug at least part of the hollow groove 103.

[0043] In some embodiments, the two hot melts 12 in the Figure 1 are heated and melted (or melted by ultrasonic technology) and extruded towards the hollow groove 103 (or extruded from the third end surface 120 to the fourth end surface 121 while extruding towards the hollow groove 103), so that the two hot melts 12 are bent towards the hollow groove 103 and contact each other; after cooling and setting, one hot melt 12 as shown in Figure 5 , Figure 6 can be formed. As can be seen from Figure 5 , Figure 6 , the hot melt 12 after melting extends to the hollow groove 103 to block at least part of the hollow groove 103.

[0044] In some embodiments, the height h of the hot melt 12 in the Figure 5 satisfies 0.35 cm < h < 0.55 cm; if h is greater than 0.55 cm, it will affect the installation of the partition plate 42; if h is less than 0.35 cm, it will cause the hot melt 12 to be easily damaged, affecting the blocking effect.

[0045] In some embodiments, preferably, the material of the hot melt 12 is liquid crystal polymer. Liquid crystal polymer has low dielectric constant, good high-frequency performance, high strength, good mechanical properties, good flowability and is beneficial to molding, and thus is suitable for being used as the material of the hot melt 12. The material of the hot melt 12 can also be resin material that can be deformed after being heated.

[0046] In some embodiments, referring to Figure 7 and Figure 8 , the application provides a terminal assembly 3, which comprises the terminal housing 1 and the terminal 2 according to any one of the embodiments; the terminal 2 comprises a terminal head 20, a needle tail 21 and a bent portion 22; the bent portion 22 has an L-shaped structure; the bent portion 22 connects the terminal head 20 and the needle tail 21; the terminal housing 1 is sleeved on the outside of the terminal 2; the first accommodating hole 100 is used for loading the bent portion 22 close to the needle tail 21 and the needle tail 21; and the second accommodating hole 110 is used for loading the bent portion 22 close to the terminal head 20 and the terminal head 20.

[0047] In some embodiments, the terminal 2 passes through the hollow groove 103 and enters the inside of the terminal housing 1.

[0048] In some embodiments, at least part of the pin tail 21 is arranged in the first accommodating hole 100; at least part of the terminal head 20 is arranged in the second accommodating hole 110. Specifically, the part of the pin tail 21 away from the bending part 22 passes through the first accommodating hole 100, and the part of the terminal head 20 away from the bending part 22 passes through the second accommodating hole 110. The pin tail 21 passing through the first accommodating hole 100 is welded with a circuit board (PCB). The terminal head 20 passing through the second accommodating hole 110 is electrically connected with a matched connector.

[0049] In some embodiments, Figure 7 、 Figure 8 indicates the terminal assembly 3 before being heated and melted, Figure 9 indicates the terminal assembly 3 after being heated and melted. It can be known from Figure 9 that the hot melt 12 after being heated and melted and being cooled and shaped can block at least part of the hollow groove 103, so as to avoid the terminal 2 from being separated from the terminal shell 1 through the hollow groove 103, and thus the terminal 2 can transmit signals more stably, and the signal transmission quality is improved.

[0050] In some embodiments, referring to Figures 10 to 13 , the application provides a connector, which comprises a plurality of terminal assemblies 3 according to any one of the above embodiments and a connector shell 4; the connector shell 4 comprises a third part 40 and a fourth part 41 connected with each other; the third part 40 comprises a plurality of plug-in parts 400 and a first accommodating cavity 401 connected with the plurality of plug-in parts 400; each plug-in part 400 is provided with a plug-in hole 402; the plug-in hole 402 corresponds to the terminal assembly 3 one by one; the second part 11 of the terminal shell 1 away from the first part 10 is inserted into the corresponding plug-in hole 402; the second part 11 of the terminal shell 1 close to the first part 10 and the first part 10 are inserted into the first accommodating cavity 401; the plug-in hole 402 and the first accommodating cavity 401 are in communication; the fourth part 41 is provided with a second accommodating cavity 410, and the plurality of plug-in parts 400 are inserted into the second accommodating cavity 410.

[0051] In some embodiments, the second accommodating cavity 410 penetrates through the fourth part 41, so as to expose the terminal head 20 in the plug-in part 400, and facilitate the electrical connection between the terminal head 20 and a matched connector.

[0052] Specifically, the application takes a connector composed of four terminal assemblies and a connector shell as an example for description.
