Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a terminal and a data cable. Background Technology

[0002] The data cable includes terminals and an encapsulation layer. The terminals include a metal shell and a circuit board. The circuit board passes through the tail of the metal shell so that the circuit board has an inner part located inside the metal shell and an outer part located outside the metal shell. The encapsulation layer is formed by encapsulating the terminals in the encapsulation process. The encapsulation layer covers the tail of the circuit board and the metal shell.

[0003] The drawback of existing data cables is that the structural strength of the terminals is relatively poor. When the terminals are subjected to lateral pressure perpendicular to the circuit board, the connection between the outer and inner parts is prone to breakage, resulting in a relatively short service life for the data cables. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a terminal to solve the problem that the structural strength of the terminal of the data line in the prior art is relatively poor, and the circuit board is easily damaged and broken when subjected to pressure.

[0005] In a first aspect, this utility model provides a terminal for manufacturing a data cable, comprising: a metal shell including a head and a tail disposed opposite to the head; a circuit board disposed through the tail, such that the circuit board has an inner portion located within the metal shell and an outer portion located outside the metal shell; the outer portion includes a first surface and a second surface disposed opposite to each other in its thickness direction, the first surface having a solder pad; a reinforcing base made of a rigid material, the reinforcing base enclosing the tail and the side of the outer portion near the inner surface; the solder pads being exposed outside the reinforcing base.

[0006] Furthermore, the reinforcing base has a boss on the side facing away from the head, and the boss is supported on the side of the second surface away from the first surface.

[0007] Furthermore, the side of the outer portion facing away from the inner portion protrudes from the boss.

[0008] Furthermore, the boss has two protrusions facing the first surface, and the two protrusions are respectively disposed on both sides in the width direction of the circuit board.

[0009] Furthermore, the outer surface of the reinforcing base is provided with holes for accommodating a portion of the adhesive material during the adhesive coating process.

[0010] Furthermore, the reinforcing base is provided with a through-hole, and the tail portion and the side of the outer portion near the inner portion are both accommodated in the through-hole, and the hole is connected to the through-hole.

[0011] Furthermore, the hole positions are provided in several ways.

[0012] Furthermore, the reinforcing base includes a first outer wall and a second outer wall disposed opposite to each other in the thickness direction of the metal shell, and the holes are provided on both the first outer wall and the second outer wall.

[0013] Furthermore, the reinforcing base is made of one of nylon, PC, ABS, LCP, or PBT.

[0014] Secondly, this utility model embodiment also provides a data cable, which includes an adhesive layer and a terminal shown in the first aspect above, wherein the adhesive layer covers the terminal, and the head of the metal shell of the terminal protrudes from the adhesive layer.

[0015] Compared with the prior art, the beneficial effects of the terminals provided in this embodiment of the present invention are as follows:

[0016] The terminal provided in this embodiment includes a metal housing, a circuit board, and a reinforcing base. The metal housing includes a head and a tail opposite to the head. The circuit board passes through the tail, so that the circuit board has an inner portion inside the metal housing and an outer portion outside the metal housing. The reinforcing base is made of a rigid material and wraps around the tail and the side of the outer portion near the inner portion.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] This utility model embodiment provides a terminal 1000, used in the manufacture of data cables (not shown in the figure), such as... Figures 1-3 As shown, terminal 1000 includes a metal housing 110, a circuit board 120, and a reinforcing base 130. The metal housing 110 includes a head 111 and a tail 112 opposite to the head 111. The circuit board 120 passes through the tail 112, such that the circuit board 120 has an inner portion 121 located within the metal housing 110 and an outer portion 122 located outside the metal housing 110. The reinforcing base 130 is made of a rigid material and covers the tail 112 and the side of the outer portion 122 near the inner portion 121. The outer portion 122 includes portions in its thickness direction (…). Figure 1 The first surface 1221 and the second surface 1222 are arranged opposite to each other in the X direction. The first surface 1221 is provided with a pad 1223, which is exposed outside the reinforcement base 130.

[0028] Specifically, this embodiment adds a reinforcing base 130 made of rigid material to the terminal 1000 disclosed in the prior art. The reinforcing base 130 covers the tail 112 of the metal shell 110 and the side of the outer portion 122 of the circuit board 120 near the inner portion 121. With this arrangement, the rigid reinforcing base 130 can protect the connection position between the outer portion 122 and the inner portion 121. After being protected by the reinforcing base 130, the terminal 1000 can withstand greater lateral pressure. Compared with the prior art, the connection position between the outer portion 122 and the inner portion 121 is less prone to breakage, and the data cable has a longer service life.

[0029] It's worth mentioning that data cables are less prone to damage and have a longer lifespan, which means that the amount of after-sales service can be effectively reduced, and after-sales costs will also be significantly lowered.

[0030] It should be noted that the reason why the pad 1223 is exposed outside the reinforcing base 130 is that the pad 1223 needs to be soldered together with the wire core of the data cable (not shown in the figure). If the reinforcing base 130 covers the pad 1223, the soldering of the wire core cannot be completed. Therefore, in this embodiment, the reinforcing base 130 does not cover the pad 1223, and the pad 1223 is exposed outside the reinforcing base 130.

[0031] Furthermore, when the wire core is soldered to the pad 1223, the circuit board 120 is subjected to stress. If the circuit board 120 deforms at this time, it is easy for cold solder joints to occur. Therefore, the yield rate of data cables in the prior art is relatively low. Since the reinforcing bracket 130 wraps around the side of the outer portion 122 near the inner portion 121, it can limit the deformation of the circuit board 120 to a certain extent, effectively reducing the probability of cold solder joints, and thus improving the yield rate.

[0032] There are many materials suitable for making the reinforcing base 130, such as nylon, PC, ABS, LCP, PBT, etc. This embodiment does not limit them, as long as the reinforcing base 130 can be used to protect the connection position between the outer side 122 and the inner side 121 and improve the service life of the data cable.

[0033] refer to Figures 1-3 In a specific embodiment, the reinforcing base 130 has a boss 131 on the side facing away from the head 111, and the boss 131 is supported on the side of the second surface 1222 away from the first surface 1221.

[0034] In this embodiment, by providing a boss 131 on the side of the reinforcing base 130 facing away from the head 111, the support for the side of the circuit board 120 facing away from the solder pad 1223 is enhanced. This makes the circuit board 120 less prone to deformation under stress when the wire core is soldered to the solder pad 1223, further reducing the probability of poor soldering and thus further improving the yield rate.

[0035] refer to Figures 1-3 In a specific embodiment, the outer side 122 protrudes from the boss 131 on the side opposite to the inner side 121.

[0036] Specifically, during the production of terminal 1000, a process of breaking the long circuit board 120 is performed. Only after the long circuit board 120 is broken will the terminal 1000 be formed as shown in the diagram. Figure 1As shown, the circuit board 120 has relatively short terminals 1000. The side of the outer portion 122 of the circuit board 120 facing away from the inner portion 121 is the part of the circuit board 120 that will be broken off; this is referred to as the preset break-off portion in this invention. In this embodiment, the preset break-off portion protrudes from the boss 131. If the preset break-off portion is flush with the boss 131, the fracture surface produced when breaking the circuit board 120 may not be flush, resulting in poor processing consistency. If the boss 131 protrudes from the preset break-off portion, the actual part that is broken off may differ from the preset break-off portion due to the influence of the boss 131.

[0037] To avoid the aforementioned processing problems, in this embodiment, the side of the outer portion 122 facing away from the inner portion 121 protrudes from the boss 131.

[0038] refer to Figures 1-3 In some embodiments, the boss 131 is further provided with two protrusions 1311 on the side facing the first surface 1221, and the two protrusions 1311 are respectively disposed in the width direction of the circuit board 120. Figure 1 The terminals 1000 are positioned on both sides in the Y direction (in the middle) to strengthen the constraint on the circuit board 120 in the width direction and improve the structural strength of the terminals 1000.

[0039] refer to Figures 1-3 In some embodiments, the outer surface of the reinforcing base 130 is provided with a hole 132, which is used to accommodate part of the adhesive material during the adhesive coating process.

[0040] Specifically, since the reinforcing base 130 has a hole 132 on its outer surface, when the terminal 1000 is coated with adhesive, the adhesive material will enter the hole 132, thereby giving the coating layer a pin that can be inserted into the hole 132. The pin and the hole 132 cooperate to enhance the connection stability between the coating layer and the terminal 1000, effectively reducing the probability of the coating layer and the terminal 1000 separating due to insufficient connection stability.

[0041] refer to Figures 1-3 In a specific embodiment, the reinforcing base 130 is provided with a through-hole 133, and the tail 112 and the side of the outer portion 122 near the inner portion 121 are both accommodated in the through-hole 133, and the hole 132 communicates with the through-hole 133.

[0042] Specifically, compared to the embodiment where hole 132 is not connected to port 133, in the embodiment where hole 132 is connected to port 133, hole 132 is deeper, the pin formed by the adhesive layer after adhesive coating is longer, the interlocking force between the adhesive layer and terminal 1000 is greater, and the probability of the adhesive layer and terminal 1000 separating due to insufficient connection stability can be reduced more effectively.

[0043] refer to Figures 1-3In a specific embodiment, the hole position 132 is provided with a plurality of holes.

[0044] Specifically, compared to an embodiment where there is only one hole 132, an embodiment where there are multiple holes 132 can increase the number of engagement positions between the encapsulation layer and the terminal 1000, thereby increasing the engagement force between the encapsulation layer and the terminal 1000. Therefore, it can more effectively reduce the probability of the encapsulation layer and the terminal 1000 separating due to insufficient connection stability.

[0045] refer to Figures 1-3 In a specific embodiment, the reinforcing base 130 includes a first outer wall 134 and a second outer wall 135 disposed opposite to each other in the thickness direction of the metal shell 110, and both the first outer wall 134 and the second outer wall 135 are provided with holes 132.

[0046] Specifically, compared to an embodiment where several holes 132 are concentrated on the same side of the reinforcing base 130, arranging several holes 132 on different surfaces of the reinforcing base 130 can avoid the concentration of engagement positions.

[0047] refer to Figures 1-3 In a specific embodiment, the first outer wall 134 and the second outer wall 135 each have a number of holes 132.

[0048] Specifically, compared to the embodiment where only one hole 132 is provided on both the first outer wall 134 and the second outer wall 135, providing several holes 132 on the first outer wall 134 and the second outer wall 135 can increase the number of engagement positions between the adhesive layer and the terminal 1000, thereby increasing the engagement force between the adhesive layer and the terminal 1000. Therefore, it can more effectively reduce the probability of the adhesive layer and the terminal 1000 separating due to insufficient connection stability.

[0049] This utility model embodiment also provides a data cable, such as Figures 1-3 As shown, the data cable includes a terminal 1000 and an adhesive layer (not shown). The terminal 1000 includes a metal housing 110, a circuit board 120, and a reinforcing base 130. The metal housing 110 includes a head 111 and a tail 112 opposite to the head 111. The circuit board 120 passes through the tail 112, such that the circuit board 120 has an inner portion 121 located within the metal housing 110 and an outer portion 122 located outside the metal housing 110. The reinforcing base 130 is made of a rigid material and covers the tail 112 and the side of the outer portion 122 near the inner portion 121. The outer portion 122 includes portions in its thickness direction (…). Figure 1A first surface 1221 and a second surface 1222 are arranged opposite to each other in the X direction. The first surface 1221 is provided with a solder pad 1223, which is exposed outside the reinforcing base 130. An adhesive layer covers the terminal 1000, and the head 111 of the metal shell 110 of the terminal 1000 protrudes from the adhesive layer, that is, the adhesive layer covers the part of the terminal 1000 except for the head 111 of the metal shell 110.

[0050] Specifically, this embodiment adds a reinforcing base 130 made of rigid material to the terminal 1000 disclosed in the prior art. The reinforcing base 130 covers the tail 112 of the metal shell 110 and the side of the outer portion 122 of the circuit board 120 near the inner portion 121. With this arrangement, the rigid reinforcing base 130 can protect the connection position between the outer portion 122 and the inner portion 121. After being protected by the reinforcing base 130, the terminal 1000 can withstand greater lateral pressure. Compared with the prior art, the connection position between the outer portion 122 and the inner portion 121 is less prone to breakage, and the data cable has a longer service life.

[0051] It's worth mentioning that data cables are less prone to damage and have a longer lifespan, which means that the amount of after-sales service can be effectively reduced, and after-sales costs will also be significantly lowered.

[0052] It should be noted that the reason why the solder pad 1223 is exposed outside the reinforcing base 130 is that the solder pad 1223 needs to be soldered together with the wire core of the data cable. If the reinforcing base 130 covers the solder pad 1223, the soldering of the wire core cannot be completed. Therefore, in this embodiment, the reinforcing base 130 does not cover the solder pad 1223, and the solder pad 1223 is exposed outside the reinforcing base 130.

[0053] Furthermore, when the wire core is soldered to the pad 1223, the circuit board 120 is subjected to stress. If the circuit board 120 deforms at this time, it is easy for cold solder joints to occur. Therefore, the yield rate of data cables in the prior art is relatively low. Since the reinforcing bracket 130 wraps around the side of the outer portion 122 near the inner portion 121, it can limit the deformation of the circuit board 120 to a certain extent, effectively reducing the probability of cold solder joints, and thus improving the yield rate.

[0054] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
