Description

Technical Field

[0001] This utility model relates to the field of needle holder technology, specifically a needle holder. Background Technology

[0002] In daily life, many electrical devices are connected to power or signals using pin headers. However, current pin headers typically use soldering or injection molding to fix the pin housing and pins together, which makes overall assembly or injection molding inconvenient. Furthermore, soldering often creates gaps at the connection holes, resulting in poor sealing. To address these issues, a new pin header design is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a needle holder to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a needle holder, comprising a needle holder housing, wherein a plurality of sealing needle holders are mounted on the needle holder housing, and a power connection pin is engaged on the sealing needle holder.

[0005] Preferably, the needle housing includes a needle housing body, and the inner sidewall of the needle housing body is provided with a plurality of countersunk through holes.

[0006] Preferably, the sealing needle holder includes a needle tube, which is integrally formed with the needle holder housing body and is opposite to the countersunk through hole. A sealing rubber sleeve is fixedly connected to the front end of the inner side wall of the needle tube, and an inclined locking block is integrally formed on the upper side of the tail end of the needle tube. Relief openings are provided on both sides of the tail end of the needle tube in the lateral direction.

[0007] Preferably, the connecting pin includes a pin body, the outer side wall of the pin body is integrally formed with a limiting boss, the pin body is inserted into the countersunk through hole and the sleeve tube, and the limiting boss is embedded in the countersunk through hole, the pin body is sleeved with a sealing sleeve, and the outer side wall of the pin body is provided with a retaining groove, the retaining groove is engaged with an angle retaining block.

[0008] The beneficial effects of this utility model are:

[0009] In use, the power connector can be directly inserted into the countersunk hole and out of the sleeve tube. At this time, the slot and the tilting block are engaged together, and the sealing sleeve tightly wraps around the outer wall of the power connector, which plays a role in sealing and waterproofing. This makes assembly convenient, and the needle seat shell can be injection molded separately from the power connector, which makes injection molding convenient. Attached Figure Description

[0011] Figure 2 This is a cross-sectional disassembly diagram of part of the structure of this utility model.

[0012] In the figure: needle housing 1, needle housing body 11, countersunk through hole 12, sealing needle seat 2, needle tube 21, sealing rubber sleeve 22, tilting block 23, clearance port 24, power connecting pin 3, pin body 31, limiting boss 32, and slot 33. Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a needle holder, including a needle holder shell 1, on which a plurality of sealing needle holders 2 are assembled, and electrical connection pins 3 are snapped into the sealing needle holders 2.

[0015] Specifically, the needle housing 1 includes a needle housing body 11, and the inner sidewall of the needle housing body 11 is provided with a plurality of countersunk through holes 12.

[0016] Specifically, the sealing needle holder 2 includes a needle tube 21, which is integrally formed with the needle holder housing body 11, and the needle tube 21 is opposite to the countersunk through hole 12. A sealing rubber sleeve 22 is fixedly connected to the front end of the inner side wall of the needle tube 21, and an inclined locking block 23 is integrally formed on the upper side of the tail end of the needle tube 21. Relief openings 24 are provided on both sides of the tail end of the needle tube 21 in the lateral direction.

[0017] The clearance port 24 is used to allow the tail end of the sleeve tube 21 to be elastically clearanced when the connecting pin 3 is inserted into the sleeve tube 21, so as to prevent the tilting block 23 from obstructing the insertion of the connecting pin 3.

[0018] Specifically, the connecting pin 3 includes a pin body 31, the outer side wall of which is integrally formed with a limiting boss 32. The pin body 31 is inserted into the countersunk through hole 12 and the sleeve tube 21, and the limiting boss 32 is embedded in the countersunk through hole 12. The pin body 31 is sleeved with a sealing sleeve 22. The outer side wall of the pin body 31 is provided with a slot 33, which is engaged with an angled locking block 23.

[0019] Working principle: When using this utility model, the connecting pin 3 can be directly inserted into the countersunk through hole 12 and out through the sleeve tube 21. At this time, the slot 33 and the tilting block 23 are engaged together, and the sealing sleeve 22 tightly wraps around the outer wall of the connecting pin 3, which plays a role in sealing and waterproofing. This makes assembly convenient, and the pin seat shell 1 can be injection molded separately from the connecting pin 3, which realizes the function of convenient injection molding.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
