Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a locking structure that is easy to pull out. Background Technology

[0002] The connector housing supports the corresponding connector, thus enabling the connection to be configured as a connector capable of electrical transmission. During circuit maintenance, the side latch needs to be pressed to unlock it, and then the entire connector is pulled upwards to remove the entire connector housing. In existing technology, such as... Figure 8 As shown, the connector housing has a pressing part on the side to pull out the entire housing. When unlocking, the pressing part needs to be pressed from both sides towards the middle to complete the unlocking before the connector housing can be pulled out completely. However, because the pressing part has a small area, when the operator presses it manually with their fingers, the pressure applied to the object will be more concentrated when the pressing area is small, which will cause pain to the part of the operator's fingers that are pressing. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that the operator's fingers will be painful when the pressing part is squeezed, thereby providing a locking structure that can relieve the operator's finger pressing pain and is easy to pull out.

[0004] Therefore, this utility model provides a convenient pull-out locking structure, including a pin seat and a connector housing. The housing includes a main body and several holes disposed on the upper part of the main body. Elastic locks are provided on both sides of the main body. A locking element is provided between the pin seat and the elastic lock. A pressing block is provided on the elastic lock. The elastic lock has a locked state with the locking element fixed and an unlocked state with the locking element separated. When the elastic lock is in the unlocked state, the side of the pressing block and the side of the main body are on the same horizontal plane.

[0005] Furthermore: the elastic latch is fixed to the side of the body, the elastic latch also includes an elastic rod, and a clearance groove for the elastic rod to deform is provided between the elastic rod and the body. The pressing block and the locking member are provided on the side of the elastic rod facing away from the clearance groove.

[0006] Furthermore, the elastic rod is provided with locking guards on both sides. When the pressing block switches from the locked state to the unlocked state, the side of the pressing block groove near the clearance groove deforms and the side of the pressing block and the side of the locking guard are on the same horizontal plane.

[0007] Furthermore: the locking arm includes a first guard block and a second guard block respectively disposed on both sides of the pressing block, and the clearance groove is located between the first guard block and the second guard block. When the pressing block switches from the locked state to the unlocked state, the side of the pressing block groove near the clearance groove deforms and the side of the pressing block, the side of the first guard block, and the side of the second guard block are on the same horizontal plane.

[0008] Furthermore, the needle holder is provided with a partition to restrict the movement of the housing within the needle holder.

[0009] Furthermore, the locking element includes a locking block disposed on one of the pin seat or the resilient latch, and a locking groove disposed on the other for the locking block to be inserted into.

[0010] Furthermore: the locking block is disposed on the elastic latch, and the locking groove is disposed on the pin seat.

[0011] The technical solution of this utility model has the following advantages:

[0012] 1. This utility model provides a convenient pull-out locking structure. When the housing needs to be removed from the needle holder, the operator needs to press the pressing block with their fingers and press the pressing block from both sides towards the middle. Compared with the prior art, when the pressing block is pressed from both sides towards the middle, the fingers will contact the side of the body. Thus, when the entire housing is pulled upward, the surface in contact with the fingers is the side of the pressing block and the side of the body. Compared with the prior art, the area of ​​the housing in contact with the fingers is larger. When the pressing area is larger, the pressure applied by the fingers on the object will be more dispersed, thereby relieving the operator's finger pain when pressing and making it easier for the operator to unlock.

[0013] 2. The present invention provides a convenient pull-out locking structure. The elastic lock is located on both sides of the main body. When the housing needs to be pulled upward, the elastic lock switches from the fixed state to the unlocked state. Due to the pressure of the finger, the elastic rod deforms towards the side close to the relief groove, and the fixing part is in the separated state. In this way, the entire housing can be pulled upward. Attached Figure Description

[0030] Example

[0031] This embodiment provides a convenient pull-out locking structure, including a pin seat 1 and a connector housing 2. The housing 2 includes a body 21 and a plurality of hole seats 22 disposed on the upper part of the body 21. Elastic locks 3 are provided on both sides of the body 21. A locking member 4 is provided between the pin seat 1 and the elastic lock 3. A pressing block 31 is provided on the elastic lock 3. The elastic lock 3 has a locked state with the locking member 4 fixed and an unlocked state with the locking member 4 separated. When the elastic lock 3 is in the unlocked state, the side of the pressing block 31 is on the same horizontal plane as the side of the body 21.

[0032] The specific improvements mentioned above are as follows: Figures 1-3 As shown, when it is necessary to remove the housing 2 from the needle holder 1, the operator needs to press the pressing block 31 with their fingers and press the pressing block 31 from both sides towards the middle. Compared with the prior art, when the pressing block 31 is pressed into place from both sides towards the middle, the fingers will contact the side of the body 21. Thus, when the entire housing 2 is pulled upward, the surface that the fingers contact is the side of the pressing block 31 and the side of the body 21. Compared with the prior art, the area of ​​the housing 2 that the fingers contact is larger. When the pressing area is larger, the pressure applied by the fingers to the object will be more dispersed, thereby relieving the pain in the operator's fingers when pressing, and making it easier for the operator to unlock.

[0033] Based on the above embodiments: the elastic buckle 3 is fixed to the side of the body 21, the elastic buckle 3 also includes an elastic rod 32, and an avoidance groove 5 is provided between the elastic rod 32 and the body 21 for the elastic rod 32 to deform. The pressing block 31 and the locking member 4 are provided on the side of the elastic rod 32 facing away from the avoidance groove 5.

[0034] The specific improvements mentioned above are as follows: Figures 3-5As shown, the elastic latch 3 is located on both sides of the main body 21. When the housing 2 needs to be pulled upward, the elastic latch 3 switches from the fixed state to the unlocked state. The elastic rod 32 is pressed by the finger and deforms towards the side close to the relief groove 5. The fixing part is in the separated state, so the entire housing 2 can be pulled upward.

[0035] Based on the above embodiments: the elastic rod 32 is provided with locking guard arms 6 on both sides. When the pressing block 31 switches from the locked state to the unlocked state, the side of the pressing block 31 that is close to the clearance groove 5 deforms and the side of the pressing block 31 and the side of the locking guard arm 6 are on the same horizontal plane.

[0036] The specific improvements mentioned above are as follows: Figure 5 As shown, the elastic rod 32 is provided with locking arms 6 on both sides, and the clearance groove 5 is provided in the middle of the locking arms 6. When the pressing block 31 is pressed, the elastic rod 32 deforms towards the side closer to the clearance groove 5, and finally deforms until the side of the pressing block 31 and the side of the locking arms 6 are on the same horizontal plane, so that the entire housing 2 can be pulled up.

[0037] Based on the above embodiments: the locking arm 6 includes a first guard block 61 and a second guard block 62 respectively disposed on both sides of the pressing block 31. The clearance groove 5 is located between the first guard block 61 and the second guard block 62. When the pressing block 31 switches from the locked state to the unlocked state, the side of the pressing block 31 near the clearance groove 5 deforms and the side of the pressing block 31, the side of the first guard block 61 and the side of the second guard block 62 are on the same horizontal plane.

[0038] The specific improvements mentioned above are as follows: Figure 3 and Figure 5 As shown, the locking arm 6 includes a first guard block 61 and a second guard block 62 disposed on both sides of the pressing block 31. A gap is formed between the first guard block 61 and the second guard block 62, which forms a relief groove 5 for the deformation of the elastic rod 32. By setting the first guard block 61 and the second guard block 62, it is possible to ensure that the elastic rod 32 deforms within the relief groove 5 and to provide a protective barrier for the elastic rod 32.

[0039] Based on the above embodiments: the needle holder 1 is provided with a partition 7 that restricts the movement of the housing 2 in the needle holder 1.

[0040] The specific improvements mentioned above are as follows: Figure 1 As shown, in order to ensure the positioning between the needle holder 1 and the housing 2, a partition 7 is provided on the needle holder 1 to engage with the housing 2. The partition 7 is located on the inner side wall of the needle holder 1 and abuts against the outer side wall of the housing 2. The partition 7 forms a support point between the needle holder 1 and the housing 2.

[0041] Based on the above embodiments: the locking member 4 includes a locking block 41 disposed on one of the pin seat 1 or the elastic buckle 3 and a locking groove 42 disposed on the other for the locking block 41 to be inserted.

[0042] Based on the above embodiments: the locking block 41 is disposed on the elastic buckle 3, and the locking groove 42 is disposed on the pin seat 1.

[0043] The specific improvements mentioned above are as follows: Figure 6 and Figure 7 As shown, the locking block 41 is set on the elastic latch 3, and the locking groove 42 is set on the needle seat 1. When the operator presses the locking block 31 with his finger, the elastic rod 32 deforms from both sides toward the middle. At the same time, the locking block 41 will disengage from the locking groove 42, thereby unlocking the needle seat 1 and the housing 2. The entire housing 2 can then be pulled out of the needle seat 1.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
