[0030] According to the utility model, a portable multi-head needle pushing tool is provided. Figures 1 to 5 As shown, the portable multi-head pin pushing tool is used for a socket board that needs to plug and unplug PIN terminals. The portable multi-head pin pushing tool includes a pin pushing mechanism 1 and a pin pushing housing 2.

[0031] In the following description, reference will be made to Figures 1 to 5 The detailed structures of the pin pushing mechanism 1 and the pin pushing housing 2 of the portable multi-head pin pushing tool are described in detail.

[0032] like Figures 1 to 5 As shown, in the embodiment, the push-pin mechanism 1 is detachably disposed inside the push-pin housing 2. The push-pin mechanism 1 can also be movably disposed inside the push-pin housing 2 to facilitate plugging and unplugging of the PIN terminal. Specifically, the push-pin mechanism 1 includes a main body 101, a push-pin body 102, and a movable portion 103. The push-pin body 102 and the movable portion 103 are respectively disposed at both ends of the main body 101. There are multiple push-pin bodies 102, and the multiple push-pin bodies 102 are arranged in a row at one end of the main body 101. The main body 101 can be formed into a substantially rectangular parallelepiped structure, with arc surfaces provided at both ends of the rectangular parallelepiped. Since the size of the push-pin body 102 is small, the thickness of the main body 101 can be relatively thin to reduce weight. The size of the movable portion 103 is smaller than that of the main body 101, so as to facilitate the installation of the following locking mechanism 202, while limiting the range of motion of the locking mechanism 202 so that the locking mechanism 202 can only move on the movable portion 103. There are multiple push pin bodies 102, which are arranged in sequence and spaced apart, with the spacing between them matching the spacing of the PIN terminals to be plugged in and out. The push pin body 102 can be formed into a cylindrical structure.

[0033] Furthermore, the push-pin housing 2 includes a housing body 201, a locking mechanism 202, and a push-pin wall 203. The locking mechanism 202 can be sleeved on the movable portion 103 to limit the range of movement of the push-pin mechanism 1 inside the push-pin housing 2, thereby facilitating the insertion and removal of the PIN terminal. The housing body 201 can also be formed into a substantially rectangular parallelepiped structure, and both ends of the rectangular parallelepiped structure are formed into arc surfaces, so that the housing body 201 can be adapted to the main body 101, facilitating the installation of the main body 101 inside the housing body 201. The push-pin wall 203 is provided at one end of the housing body 201, and the number of the push-pin walls 203 is multiple, and the multiple push-pin walls 203 are provided in a one-to-one correspondence with the multiple push-pin bodies 102. The push-pin wall 203 can also be formed into a cylindrical shape, and the size of the push-pin wall 203 is larger than the size of the push-pin body 102, so as to facilitate the sleeve installation of the push-pin body 102. The plurality of push pin bodies 102 arranged in a row can simultaneously plug and unplug a plurality of PIN terminals. Since the plurality of push pin bodies 102 and the plurality of push pin walls 203 are arranged in a row, the overall structure is compact and light, and is easy to carry and use. Figure 5As shown, the locking mechanism 202 is sleeved on the movable portion 103, and then Figure 5 The pin pushing mechanism 1 is installed inside the pin pushing housing 2, and the movement of the pin pushing mechanism 1 is restricted by the installed locking mechanism 202, so as to facilitate the insertion and removal of the PIN terminal.

[0034] This portable multi-pin pusher tool can achieve the insertion and removal of PIN terminals through the cooperation of the pusher mechanism 1 and the pusher housing 2. During use, the locking mechanism 202 is mounted on the movable portion 103 to limit the movement of the pusher mechanism 1 within the pusher housing 2, thereby assisting in the insertion and removal process. The tool can also accommodate PIN terminals of different specifications and models. Because the multiple pusher bodies 102 are arranged in a row on the main body 101, the overall structure is compact and lightweight, making it easy to carry. There is no need to secure the connector before pushing the pins, and the operation steps are simple and easy to operate. Due to the cooperation of the multiple pusher walls 203 and the multiple pusher bodies 102, multiple PIN terminals can be inserted and removed simultaneously, improving work efficiency and avoiding damage to the connector during insertion and removal.

[0035] Preferably, if Figures 1 to 5 As shown, in the embodiment, the end of the movable portion 103 away from the main body 101 is provided with a push pin cover 104, and the push pin cover 104 is detachably connected to the movable portion 103. The end of the movable portion 103 away from the main body 101 can be provided with a clamping block, and the end surface of the push pin cover 104 facing the movable portion 103 can be provided with a connecting groove, and the detachable connection is achieved by the clamping method of the clamping block and the connecting groove. Alternatively, the end of the movable portion 103 away from the main body 101 can be provided with an elastic pin, and the end surface of the push pin cover 104 facing the movable portion 103 is provided with a groove, and the detachable connection is achieved by the clamping method of the elastic pin and the groove. However, it is not limited to this, as long as the push pin cover 104 and the movable portion 103 can be detachably connected. In this way, when it is necessary to install the locking mechanism 202, the push pin cover 104 is removed, and the locking mechanism 202 is sleeved on the movable portion 103, and then the push pin cover 104 is installed.

[0036] Preferably, if Figures 1 to 5 As shown, in the embodiment, the size and shape of the locking mechanism 202 correspond to the size and shape of the housing body 201 , so that the locking mechanism 202 can be installed on the housing body 201 .

[0037] Preferably, if Figures 1 to 5As shown, in this embodiment, the interior of the housing body 201 is hollow to accommodate the push-pin mechanism 1. A push-pin wall 203 is provided at the first end of the housing body 201, and an accommodating hole (not shown for angle reasons) is provided at the second end of the housing body 201. The accommodating hole can be, for example, a through hole, through which the push-pin mechanism 1 is disposed within the hollow interior of the housing body 201. The interior of the push-pin wall 203 is also hollow to accommodate the push-pin body 102.

[0038] Preferably, if Figures 1 to 5 As shown, in this embodiment, the inner side wall of the receiving hole is provided with a first locking groove (not shown for angle reasons), and the first end of the locking mechanism 202 is provided with a locking ring block 204. The first end of the locking mechanism 202 faces the receiving hole, and the locking ring block 204 protrudes from the end surface of the first end of the locking mechanism 202 toward the receiving hole. The locking mechanism 202 is connected to the housing body 201 through the locking ring block 204 and the first locking groove. The locking mechanism 202 is detachably provided at one end of the housing body 201. When in use, the locking mechanism 202 can be removed from the housing body 201 and placed on the movable portion 103. During transportation, to prevent the locking mechanism 202 from being lost, the locking mechanism 202 can be installed on the housing body 201.

[0039] Preferably, if Figures 1 to 5 As shown, in the embodiment, the second end of the locking mechanism 202 is provided with a mounting groove, such as Figure 4 As shown, the push pin cover 104 can be disposed inside the mounting groove. In the case of transport, the push pin mechanism 1 can be disposed inside the push pin housing 2. In order to prevent the locking mechanism 202 from being lost, a mounting groove is provided at the second end of the locking mechanism 202. The inner wall size of the mounting groove corresponds to the outer wall size of the push pin cover 104, so that the locking mechanism 202 can be sleeved on the push pin cover 104.

[0040] Preferably, if Figures 1 to 5 As shown, in the embodiment, in order to limit the movable range of the locking mechanism 202 , the size of the main body 101 is larger than that of the movable portion 103 , so that the locking mechanism 202 can only move on the movable portion 103 .

[0041] Preferably, if Figures 1 to 4 As shown, in the embodiment, the number of the push pin bodies 102 and the number of the push pin walls 203 are both five, so that five PIN terminals can be plugged in and out at the same time.

[0042] Preferably, if Figures 1 to 5As shown, in the embodiment, when the push-pin mechanism 1 is disposed inside the push-pin housing 2, the push-pin body 102 is disposed inside the push-pin wall 203, the main body 101 is disposed inside the housing body 201, the first portion of the movable portion 103 is disposed inside the housing body 201, and the second portion of the movable portion 103 is located outside the housing body 201. The total length of the movable portion 103 and the main body 101 is greater than the length of the housing body 201 to ensure that part of the movable portion 103 is located outside the housing body 201, and the locking mechanism 202 is sleeved on this part of the movable portion 103.

[0043] Preferably, if Figure 4 As shown in FIG, the transport state of the portable multi-head push pin tool is as follows: Figure 5 The figure shows the pin push mechanism 1 in use. In this embodiment, the portable multi-head pin push tool can be switched between a transport state and a use state. When the portable multi-head pin push tool is in the transport state, the pin push mechanism 1 is located inside the pin push housing 2, the pin push body 102 is disposed inside the pin push wall 203, and a use gap is provided between the end of the pin push body 102 and the end of the pin push wall 203. This use gap can be used for plugging and unplugging PIN terminals in the following use state. When the portable multi-head pin push tool is in use, the locking mechanism 202 is sleeved on the movable portion 103, the main body 101 is located inside the housing body 201, and the pin push body 102 is located inside the pin push wall 203.

[0044] like Figure 6 The figure shows the operating principle of this portable multi-pin push-pin tool. After the terminal body 4 (i.e., the aforementioned PIN terminal) is inserted into the connector body 3, the barb 5 unfolds, and the internal locking position of the connector body 3 and the barb 5 engage with each other to secure the terminal body 4. During insertion and removal, the portable multi-pin push-pin tool retracts the barb 5 through the push-pin wall 203 and uses the push-pin body 102 to push the terminal body 4 out of the socket, thereby removing the terminal body 4 from the connector. Finally, the push-pin tool is removed and recovered, completing the entire insertion and removal process.

[0045] When using the portable multi-head push pin tool, remove the push pin cover 104. The locking mechanism 202 is a hollow design. The movable part 103 (such as Figure 5 As shown), the locking mechanism 202 can move freely up and down the movable portion 103, as shown Figure 2 and Figure 4As shown, the housing body 201 is hollow in design. After the push-pin mechanism 1 is placed into the housing body 201, it is tightly fitted with the housing body 201 through the locking mechanism 202, so that it cannot move relative to the housing body 201. In this way, the push-pin mechanism 1 can move up and down in the housing body 201. When the push-pin is upward, the size difference between the wide body part inside the push-pin and the locking position of the locking mechanism 202 can limit the push-pin mechanism 1 from separating from the housing body 201. When the push-pin is downward, the size of the locking mechanism 202 can limit the push-pin mechanism 1 from infinite downward movement, that is, the range of movement is the movable part 103. According to the above-mentioned usage principle, the portable multi-head push-pin tool can be used to insert it into the socket of the connector. Pushing the push-pin mechanism 1 can realize pushing out all five terminals at once, improving the efficiency of replacing the wiring harness, saving time, and being simple to operate, saving time and effort.

[0046] This portable multi-pin pusher tool can achieve the insertion and removal of PIN terminals through the cooperation of the pusher mechanism and the pusher housing. During use, a locking mechanism is installed on the movable part to limit the movement of the pusher mechanism inside the pusher housing to assist in the insertion and removal action. It can also accommodate PIN terminals of different specifications and models. Because multiple pusher bodies are arranged in a row on the main body, the overall structure is compact and lightweight, making it easy to carry. There is no need to fix the connector before pushing the pins, and the operation steps are simple and easy to operate. Due to the cooperation of multiple pusher walls and multiple pusher bodies, multiple PIN terminals can be inserted and removed simultaneously, improving work efficiency and avoiding damage to the connector during insertion and removal.

[0047] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto. Although the present application has been described in detail with reference to the above-described embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily conceive of changes to the technical solutions described in the above-described embodiments within the technical scope disclosed in the present application, or perform equivalent replacements for some of the technical features thereof.
