Description

TECHNICAL FIELD

[0001] The utility model relates to the surface treatment technical field of special engineering plastics, especially to a kind of for carbon fiber reinforced polyether ether ketone electric connector shell electroplating hanger. BACKGROUND

[0002] Polyether ether ketone (PEEK) is a kind of special thermoplastic engineering plastics with excellent properties such as high temperature resistance, chemical resistance, radiation resistance, flame resistance, hydrolysis resistance, etc. After filling carbon fiber, glass fiber for composite reinforcement, the comprehensive performance of the material can be greatly improved, and the high-performance injection molding parts manufactured thereby have important application prospects in high-tech fields such as electronics, medical treatment, automobiles, aerospace, etc. However, due to its poor surface conductivity, it cannot meet the performance requirements of electromagnetic shielding, etc., and cannot directly replace metal parts to achieve the purpose of weight reduction, so the application range is limited. In order to make the carbon fiber reinforced polyether ether ketone shell meet the conductive shielding performance requirements of electronic component shell, it is necessary to carry out metallization treatment on its surface, i.e. electroplating, and the existing electroplating hanger cannot meet the production requirements when electroplating the carbon fiber reinforced polyether ether ketone electric connector shell, because the current density distribution is affected by factors such as hanger size and loading capacity, resulting in large thickness deviation of the plating layer of parts at different positions. SUMMARY

[0003] The utility model discloses in order to overcome the insufficient in the prior art, provide a kind of for carbon fiber reinforced polyether ether ketone electric connector shell electroplating hanger, ensure that carbon fiber reinforced polyether ether ketone electric connector shell electroplating when the plating layer thickness of each position plating piece is uniform, and deviation rate is small.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A hanger for electroplating a carbon fiber reinforced polyether ether ketone electric connector shell includes a conductive frame and a plurality of conductive connection assemblies. The conductive frame and the conductive connection assemblies are both made of metal material. The conductive frame includes at least two vertical rods, and at least one horizontal rod is connected between adjacent two vertical rods. Each vertical rod has a conductive hook connected to its upper end. The conductive connection assemblies are vertically spaced apart on the vertical rods, and all the conductive connection assemblies are oriented in the same direction.

[0006] In the above technical solution, the upper end of each vertical rod is connected to a conductive hook, so that each vertical rod can be hung on the conductive beam on the electroplating tank and realize electrical connection, so that the potential of each vertical rod is more uniform. The crossbar can make the structure between the vertical rods stable and not easy to deform, and at the same time can short-circuit each vertical rod to reduce the potential difference between the vertical rods. A number of conductive connection components arranged at vertical intervals can add multiple workstations while ensuring that the potential difference is as small as possible, so as to realize the electroplating of multiple products at the same time, thereby improving the electroplating efficiency. All conductive connection components are facing the same direction in the electroplating tank, which can make the potential on the conductive connection components more uniform. The above solution can ensure that the shell coating thickness at each position of the carbon fiber reinforced polyetheretherketone electrical connector shell is uniform and the deviation rate is small during electroplating.

[0007] Preferably, one of the cross bars between two adjacent vertical bars is connected to the lower ends of the two vertical bars.

[0008] In the above technical solution, when the horizontal bar is connected to the lower ends of the two vertical bars, the current can be better conducted between the vertical bars, thereby ensuring that the lower parts of the two adjacent vertical bars have the same potential. This potential consistency is further transmitted downward, reducing the potential difference between the conductive connection components on each vertical bar, which helps to improve the uniformity of electroplating and product quality.

[0009] Preferably, the conductive connection assembly includes an internal clamp-type connection assembly, which includes a first support rod and a second support rod, the first end of the first support rod is fixed to and electrically connected to the vertical rod, and the other end is suspended and fixed with a first support hook, the first end of the second support rod is fixed to and electrically connected to the vertical rod, and the other end is suspended and fixed with a second support hook, the first support hook and the second support hook extend into the electrical connector housing and support the electrical connector housing.

[0010] In the above technical solution, the first and second support rods respectively receive electrical energy from the vertical rod and transmit it to the first and second support hooks. The first and second support hooks are adapted to fit into the hole structure of the electrical connector housing. When inserted into the hole, they are stretched outward to firmly fix the electrical connector housing between the first and second support hooks, thereby ensuring a good electrical connection and a stable positional relationship between the electrical connector housing and the conductive connection assembly during the electroplating process, which is conducive to achieving uniform electroplating.

[0011] Preferably, the outer surface of the first support rod and the outer surface of the second support rod are both wrapped with insulating glue;

[0012] And / or, the outer surface of the horizontal rod is wrapped with insulating glue, and the outer surface of the vertical rod is wrapped with insulating glue.

[0013] In the above technical solution, the insulating adhesive wrapping can play a role in isolating the conductive material. The surface coating of the insulating adhesive can prevent the surfaces of the horizontal rod, vertical rod, first support rod and second support rod from being accidentally plated during the electroplating process, thereby reducing the consumption of electroplating solution. The insulating adhesive can be Teflon.

[0014] Preferably, the first end of the first support rod is in close contact with and electrically connected to the first end of the second support rod, and the suspended end of the first support rod is spaced apart from the suspended end of the second support rod.

[0015] In the above technical solution, the first support rod and the second support rod are tightly fitted and electrically connected at one end near the vertical rod, which ensures that the current is conducted unimpeded between the two, so that they have the same potential starting point. The spacing at the suspended end is set to give it a certain degree of flexibility and better adapt to the shape and fixing requirements of the electrical connector housing. Through this structural design, the potential consistency between the first support rod and the second support rod in the same conductive connection assembly can be maintained throughout the electroplating process, and the potential difference is minimized, thereby ensuring that the current density received by various parts of the electrical connector housing is more uniform, which is conducive to improving the electroplating quality and making the plating layer more uniform and dense.

[0016] Preferably, the conductive connection assembly includes an external clamp-type connection assembly, which includes a third support rod and a fourth support rod, the first end of the third support rod is fixed to and electrically connected to the vertical rod, and the other end is suspended and fixed with a third support hook, the first end of the fourth support rod is fixed to and electrically connected to the vertical rod, and the other end is suspended and fixed with a fourth support hook, the third support hook extends into the electrical connector housing and supports the electrical connector housing, and the fourth support hook rests against the outside of the electrical connector housing.

[0017] In the above technical solution, the third support rod and the fourth support rod respectively obtain electrical energy from the vertical rod and transmit it to the third support hook and the fourth support hook. The third support hook can extend into the electrical connector housing to provide internal support for the electrical connector housing, while the fourth support hook rests against the outside of the electrical connector housing, applying force to the electrical connector housing from both the inside and the outside. Through the coordinated action of the third support hook and the fourth support hook, the electrical connector housing can be firmly clamped, which is particularly suitable for electrical connector housings that cannot be fixed by internal clamp-type connection components. This structural design ensures that the electrical connector housing and the conductive connection component maintain good electrical connection and a stable positional relationship during the electroplating process, which is conducive to achieving uniform electroplating.

[0018] Preferably, the fourth support hook includes a connecting portion and a bending portion, the extending direction of the connecting portion is the same as the extending direction of the fourth support rod, and the angle between the bending portions is α, 60°≤α≤120°.

[0019] In the above technical solution, the angle α within the range of 60°≤α≤120° increases the contact area between the bent portion and the component, allowing the fourth support hook to more evenly distribute pressure when abutting the component, better securing the component and preventing displacement during the electroplating process. The angled bent portion provides a better fit with the component surface, increasing connection reliability and ensuring that the electrical connector housing remains stably in its designated position during the electroplating process, facilitating a uniform coating.

[0020] Preferably, the outer surface of the third support rod and the outer surface of the fourth support rod are both wrapped with insulating glue.

[0021] In the above technical solution, the wrapping of insulating glue can play the role of isolating the conductor. The surface wrapping of insulating glue can prevent the surfaces of the third support rod and the fourth support rod from being accidentally plated during the electroplating process, which can reduce the consumption of electroplating solution.

[0022] Preferably, the first end of the third support rod is in close contact with and electrically connected to the first end of the fourth support rod, and the suspended end of the third support rod is spaced apart from the suspended end of the fourth support rod.

[0023] In the above technical solution, the third and fourth support rods fit tightly together and are electrically connected at the end closest to the vertical rod, ensuring that current can flow unimpeded between them, so that they have the same potential from the starting end. The spacing of the suspended ends is designed to better adapt to the shape and fixing requirements of the electrical connector housing. Through this structural design, the third and fourth support rods in the same conductive connection assembly can maintain a consistent potential throughout the electroplating process, thereby minimizing the potential difference. This helps all parts of the electrical connector housing receive a uniform current density, thereby improving the electroplating quality and making the coating more uniform and dense.

[0024] Preferably, a hand-held handle is provided on the upper portion of the vertical rod, and the direction of the hand-held handle is opposite to the direction of the electrical connection assembly.

[0025] In the above technical solution, the handheld handle makes it convenient for workers to take and place the hanger. Since the handheld handle is facing opposite to the electrical connection component, when the worker takes and places the hanger, the handheld handle will not interfere with the connection between the electrical connection component and the electroplating equipment or the electrical connector housing.

DETAILED DESCRIPTION

[0032] The utility model will be further described below in combination with the drawings and specific embodiments.

[0033] Embodiment 1:

[0034] As Figures 1 to 5 shown, a kind of for carbon fiber reinforced polyether ether ketone electric connector shell electroplating hanger, including conductive frame 1 and several conductive connecting assemblies 2, the conductive frame 1 and conductive connecting assembly 2 are all made of metal material, the conductive frame 1 includes two vertical rods 11, at least one horizontal rod 12 is connected between adjacent two vertical rods 11, the upper end of each vertical rod 11 is connected with conductive hook 13, the conductive connecting assembly 2 is vertically spaced apart and arranged in the vertical rod 11, all conductive connecting assemblies 2 are towards the same direction.

[0035] In the above technical solution, the upper end of each vertical rod 11 is connected with conductive hook 13, so that each vertical rod 11 can be hung on the conductive crossbeam on the electroplating tank and realize electrical connection, so that the potential of each vertical rod 11 is more uniform. The horizontal rod 12 can stabilize the structure between the vertical rods 11 and is not easy to deform, and can short-circuit each vertical rod 11 to reduce the potential difference between the vertical rods 11. Several conductive connecting assemblies 2 vertically spaced apart can add multiple stations under the condition that potential difference is as small as possible, realize simultaneous electroplating of multiple products, and then improve electroplating efficiency. All conductive connecting assemblies 2 are towards the same direction in the electroplating tank, which can make the potential on the conductive connecting assembly 2 more uniform.

[0036] Specifically, a plurality of horizontal rods 12 are provided between adjacent two vertical rods 11, and one of the horizontal rods 12 is connected to the lower end of the two vertical rods 11.

[0037] In the above technical solution, when the horizontal rod 12 is connected to the lower ends of the two vertical rods 11, the current can be better conducted between the vertical rods 11, thereby ensuring that the lower potential of two adjacent vertical rods 11 remains consistent. This potential consistency is further transmitted downward, reducing the potential difference of the conductive connection components 2 on each vertical rod 11, which helps to improve the uniformity of electroplating and product quality.

[0038] Specifically, a handheld handle 3 is provided on the upper portion of the vertical rod 11, and the handheld handle 3 is oriented opposite to the electrical connection assembly. In the above technical solution, the handheld handle 3 facilitates workers to remove and place the hanger. Since the handheld handle 3 is oriented opposite to the electrical connection assembly, when workers remove and place the hanger, the handheld handle 3 will not interfere with the connection between the electrical connection assembly and the electroplating equipment or the electrical connector housing.

[0039] Example 2:

[0040] like Figure 1 and Figure 2 As shown, on the basis of Example 1, the conductive connection component 2 includes an internal clamp-type connection component 21, and the internal clamp-type connection component 21 includes a first support rod 211 and a second support rod 212. The first end of the first support rod 211 is fixed to the vertical rod 11 and electrically connected, and the other end is suspended and fixed with a first support hook 213. The first end of the second support rod 212 is fixed to the vertical rod 11 and electrically connected, and the other end is suspended and fixed with a second support hook 214. The first support hook 213 and the second support hook 214 extend into the electrical connector housing and support the electrical connector housing.

[0041] In the above technical solution, the first support rod 211 and the second support rod 212 respectively obtain electrical energy from the vertical rod 11 and transmit it to the first support hook 213 and the second support hook 214. The first support hook 213 and the second support hook 214 can adapt to the hole structure on the electrical connector housing. When inserted into the hole, the electrical connector housing can be firmly fixed between the first support hook 213 and the second support hook 214 by stretching outward, thereby ensuring that the electrical connector housing and the conductive connection assembly 2 maintain a good electrical connection and a stable positional relationship during the electroplating process, which is conducive to achieving uniform electroplating. The conductive frame 1 is made of copper, the first support rod 211 and the second support rod 212 are made of copper, and the first support hook 213 and the second support hook 214 are made of stainless steel.

[0042] Preferably, the outer surfaces of the first support rod 211 and the outer surfaces of the second support rod 212 are both coated with insulating adhesive. The outer surfaces of the horizontal rod 12 and the vertical rod 11 are also coated with insulating adhesive. The metal on the conductive hook 13 is directly exposed, and the metal on the first support hook 213 and the second support hook 214 is directly exposed.

[0043] In the above technical solution, the insulating adhesive wrapping can play a role in isolating the conductive material. The surface coating with the insulating adhesive can prevent the surfaces of the horizontal rod 12, the vertical rod 11, the first support rod 211 and the second support rod 212 from being accidentally plated during the electroplating process, thereby reducing the consumption of the electroplating solution. The insulating adhesive can be Teflon.

[0044] Preferably, the first end of the first support rod 211 is in close contact with and electrically connected to the first end of the second support rod 212 , and the suspended end of the first support rod 211 and the suspended end of the second support rod 212 are spaced apart.

[0045] In the above technical solution, the first support rod 211 and the second support rod 212 are tightly fitted and electrically connected at one end close to the vertical rod 11, which ensures that the current is conducted unimpeded between the two, so that they have the same potential starting point. The spacing at the suspended end is to give it a certain degree of elasticity so that it can better adapt to the shape and fixing requirements of the electrical connector housing. Through this structural design, during the entire electroplating process, the first support rod 211 and the second support rod 212 in the same conductive connection component 2 can maintain a consistent potential, and the potential difference is minimized as much as possible, thereby ensuring that the current density received by each part of the electrical connector housing is more uniform, which is conducive to improving the electroplating quality and making the coating more uniform and dense.

[0046] Example 3:

[0047] like Figures 3 to 5 As shown, on the basis of Example 1, the conductive connection component 2 includes an external clamping connection component 22, and the external clamping connection component 22 includes a third support rod 221 and a fourth support rod 222. The first end of the third support rod 221 is fixed to and electrically connected to the vertical rod 11, and the other end is suspended and fixed with a third support hook 223. The first end of the fourth support rod 222 is fixed to and electrically connected to the vertical rod 11, and the other end is suspended and fixed with a fourth support hook 224. The third support hook 223 extends into the electrical connector housing and supports the electrical connector housing, and the fourth support hook 224 rests on the outside of the electrical connector housing.

[0048] In the above technical solution, the third support rod 221 and the fourth support rod 222 draw electrical energy from the vertical rod 11 and transmit it to the third support hook 223 and the fourth support hook 224, respectively. The third support hook 223 can extend into the electrical connector housing, providing internal support for the electrical connector housing, while the fourth support hook 224 abuts against the outside of the electrical connector housing, applying force to the electrical connector housing from both the inside and outside. The coordinated action of the third support hook 223 and the fourth support hook 224 can securely clamp the electrical connector housing, making it particularly suitable for electrical connector housings that cannot be secured by the internal clamp-type connection assembly 21. This structural design ensures a good electrical connection and a stable positional relationship between the electrical connector housing and the conductive connection assembly 2 during the electroplating process, facilitating uniform electroplating. The conductive frame 1 is made of copper, the third support rod 221 and the fourth support rod 222 are made of copper, and the third support hook 223 and the fourth support hook 224 are made of stainless steel.

[0050] In the above technical solution, the angle α within the range of 60°≤α≤120° can increase the contact area between the bent portion 2242 and the component, allowing the fourth support hook 224 to more evenly distribute pressure when abutting the component, better securing the component and preventing displacement during the electroplating process. The angled bent portion 2242 can better conform to the component surface, increasing connection reliability and ensuring that the electrical connector housing remains stably in the set position during the electroplating process, facilitating a uniform coating.

[0051] Preferably, the outer surfaces of the third support rod 221 and the outer surfaces of the fourth support rod 222 are coated with insulating adhesive. The metal on the conductive hook 13 is directly exposed, and the third support hook 223 and the fourth support hook 224 are directly exposed. In the above technical solution, the insulating adhesive coating can isolate the conductive material. The surface coating of the insulating adhesive can prevent the surfaces of the third support rod 221 and the fourth support rod 222 from being accidentally plated during the electroplating process, thereby reducing the consumption of electroplating solution.

[0052] Preferably, the first end of the third support rod 221 is in close contact with and electrically connected to the first end of the fourth support rod 222 , and the suspended end of the third support rod 221 and the suspended end of the fourth support rod 222 are spaced apart.

[0053] In the above technical solution, the third support rod 221 and the fourth support rod 222 are tightly fitted and electrically connected at one end near the vertical rod 11, ensuring that current can be conducted unimpeded between the two, so that they have the same potential from the starting end. The spacing between the suspended ends is to give them a certain degree of elasticity so that they can better adapt to the shape and fixing requirements of the electrical connector housing. Through this structural design, the third support rod 221 and the fourth support rod 222 in the same conductive connection assembly 2 can maintain a consistent potential throughout the electroplating process, thereby minimizing the potential difference. This is conducive to each part of the electrical connector housing receiving a uniform current density, thereby improving the electroplating quality and making the coating more uniform and dense.
