Description

Technical Field

[0001] This utility model relates to the field of pin installation, and in particular to a quick assembly and fixing device for pins. Background Technology

[0002] A pin is a metallic material in a connector used to conduct electricity (signal) and typically consists of a sleeve, a pin head and a pin tail located at both ends of the sleeve, and a spring located inside the sleeve.

[0003] After PCB production, quality inspection is usually carried out. At this time, multiple pins need to be arranged and combined together. The pins play a conductive role in connecting the PCB to the test chip. Currently, the industry usually uses special test sockets for PCB testing. The pins are directly fixed on the test sockets, which means that the test socket and the PCB being tested usually correspond one-to-one. When changing the PCB to be tested, the entire test socket is usually replaced, which is costly. The inventor of this invention aims to provide a technical solution to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a quick assembly and fixing device for pins, which has the advantage of eliminating the need to replace the entire test socket when changing the PCB board to be tested, thus reducing the cost of use.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution: a pin quick assembly and fixing device, comprising:

[0006] A support base that is detachably fixed to the test fixture, the support base having a first placement hole for inserting one end of a pin and allowing the pin end to protrude from the support base; and...

[0007] The cover is fixed to the support base by a buckle. The cover has a second placement hole that corresponds to the first placement hole. The second placement hole penetrates the cover so that the tip of the pin protrudes from the cover.

[0008] With the above technical solution, when installing the pins, place one end of the pin tail into the first placement hole. After filling the first placement hole, snap the cover onto the support. At this time, the pin tip automatically enters the second placement hole. After the pin installation is completed, install the support onto the test socket. When the PCB needs to be replaced, only a new support and cover need to be customized as needed. After the pin is re-fixed between the support and cover, the new support is fixed onto the test socket. There is no need to replace the entire test socket, which reduces the cost of use.

[0009] In one embodiment of the present invention, the first placement hole includes: an a hole that communicates with the side of the support base near the cover and is adapted to the sleeve of the pin; and a b hole that communicates with the a hole and the side of the support base away from the cover at both ends, respectively, wherein the size of the b hole is adapted to the tail of the pin and the length is less than the length of the tail.

[0010] With the above technical solution, the sleeve cannot enter hole b, thereby preventing the pin from coming out of the support and fixing the pin stably.

[0011] In one embodiment of the present invention, the second placement hole includes: a c-hole that communicates with the side of the cover near the support and is adapted to the sleeve of the pin; and a d-hole whose two ends communicate with the c-hole and the side of the cover away from the support, respectively, wherein the size of the d-hole is adapted to the tip of the pin and its length is less than the length of the pin.

[0012] With the above technical solution, the sleeve cannot enter the d hole, thereby preventing the pin from coming out of the cover and thus achieving stable fixation of the pin.

[0013] In one embodiment of the present invention, a first locking block is fixed on a pair of opposite sides of the cover. A first clearance opening is provided through the cover near the first locking block. The first locking block is pressed towards the direction of the first clearance opening to move the first locking block. After the pressing stops, the first locking block rebounds. A first slot is provided on the support base to cooperate with the first locking block.

[0014] By using the above technical solution, when assembling the cover and the support, the side where the first locking block is located is manually squeezed inward, thereby moving the first locking block to compress the width of the cover. After the cover is placed on the support and the first locking block is located in the first locking groove, the squeezing is stopped, and the first locking block rebounds and locks into the first locking groove, thereby fixing the cover and the support.

[0015] In one embodiment of the present invention, a second locking block is fixed on a pair of opposite sides of the support base to secure the support base to the test base.

[0016] The above technical solution uses a second locking block to secure the support base to the test base, making disassembly convenient.

[0017] In one embodiment of the present invention, the support base has mounting holes for mounting the support base onto the test base by screws.

[0018] The above technical solution uses screws to fix the support base to the test base, thus ensuring stability while facilitating disassembly.

[0019] In one embodiment of the present invention, a top-out hole is provided through the support base, and the cover is located at one end of the top-out hole when it is fixed to the support base.

[0020] The above technical solution allows for the rapid ejection and separation of the cover from the support by inserting a push rod through the ejection hole, thereby enabling the rapid recycling and reuse of the ejector pin.

[0021] As described above, the pin quick assembly and fixing device of this utility model has the following beneficial effects:

[0022] When installing the pins, place one end of the pin into the first placement hole. After filling the first placement hole, snap the cover onto the support. At this point, the pin tip will automatically enter the second placement hole. After completing the pin installation, install the support onto the test socket. When the PCB needs to be replaced, simply customize a new support and cover as needed, re-fix the pins between the support and cover, and then fix the new support onto the test socket. This eliminates the need to replace the entire test socket, reducing usage costs. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figure 1 and Figure 3 This utility model provides a quick assembly and fixing device for pins, comprising:

[0030] The support base 1 is detachably fixed to the test seat. The support base 1 is arranged in a horizontal direction. The support base 1 has a first placement hole 2 for inserting one end of the pin tail 18 and making the pin tail 18 protrude from the support base 1. The first placement hole 2 includes: an a hole 5 that communicates with the side of the support base 1 near the cover 3 and is adapted to the sleeve 16 of the pin; and a b hole 6 that communicates with the a hole 5 and the side of the support base 1 away from the cover 3 at both ends respectively. The size of the b hole 6 is adapted to the pin tail 18 and the length is less than the length of the pin tail 18, so that when the pin is placed in the first placement hole 2, the pin tail 18 is exposed from below the support base 1.

[0031] Please see Figure 1 and Figure 3 It also includes a cover 3 fixed to the support base 1 by a snap fastener. A receiving groove for accommodating the cover 3 is opened on the upper surface of the support base 1. The size of the cover 3 is adapted to the size of the receiving groove. A second placement hole 4 is opened on the cover 3, which is corresponding to the first placement hole 2. The second placement hole 4 is set through the cover 3 so that the needle tip 17 of the pin protrudes from the cover 3. The second placement hole 4 includes: a c hole 7 that communicates with the side of the cover 3 near the support base 1 and is adapted to the sleeve 16 of the pin; and a d hole 8 that communicates with the c hole 7 and the side of the cover 3 away from the support base 1 at both ends respectively. The size of the d hole 8 is adapted to the needle tip 17 of the pin and the length is less than the length of the needle tip 17 so that when the pin is placed in the second placement hole 4, the needle tip 17 is exposed from above the cover 3.

[0032] Please see Figure 2 A first locking block 9 is fixed on a pair of opposite sides of the cover 3. A first clearance opening 10 is opened vertically on the side of the cover 3 near the first locking block 9. The first locking block 9 is pressed towards the direction of the first clearance opening 10 to move the first locking block 9. After the pressing stops, the first locking block 9 rebounds. A first slot 11 that cooperates with the first locking block 9 is opened on the support base 1. When assembling the cover 3 and the support base 1, the side where the first locking block 9 is located is manually pressed inward, so that the first locking block 9 moves and compresses the width of the cover 3. After the cover 3 is placed on the support base 1 and the first locking block 9 is located in the first slot 11, the pressing stops, and the first locking block 9 rebounds and is locked into the first slot 11, thereby fixing the cover 3 and the support base 1.

[0033] Please see Figure 2A second locking block 12 is fixed on a pair of opposite sides of the support base 1 to lock the support base 1 onto the test base. A second clearance opening 15 is provided vertically on the side of the support base 1 near the second locking block 12. The second locking block 12 is pressed toward the direction of the second clearance opening 15 to move the second locking block 12, compressing the length of the support base 1 and installing the support base 1 into the pre-opened slot on the test base, thereby fixing the support base 1 to the test base. When disassembling the support base 1, the second locking block 12 can be pressed again, making disassembly simple and convenient.

[0034] Mounting holes 13 are also provided on the support base 1. In other embodiments, the support base 1 and the test base can be fixed by screws instead of using the second locking block 12.

[0035] Please see Figure 2 The support base 1 also has a vertically penetrating ejection hole 14, which is connected to the receiving groove, so that when the cover 3 is fixed to the support base 1, it is located at one end of the ejection hole 14. In addition to disassembling the cover 3 from the support base 1 by squeezing the first locking block 9, the cover 3 can also be ejected by passing through the ejection hole 14 with a push rod to separate the cover 3 from the support base 1.

[0036] In this invention, when installing the pin, one end of the pin tail 18 is placed in the first placement hole 2. After filling the first placement hole 2, the cover 3 is fastened to the support base 1. At this time, the pin tip 17 automatically enters the second placement hole 4. After the pin installation is completed, the support base 1 is installed on the test base. When the PCB board needs to be replaced, only a new support base 1 and cover 3 need to be customized as needed. After the pin is re-fixed between the support base 1 and cover 3, the new support base 1 is fixed on the test base. There is no need to replace the entire test base, which reduces the cost of use.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
