The utility model discloses a rivet draw-in groove, the rivet head can be impressed in the rivet draw-in groove when pushing down the wire, consequently can not form the gap between rivet and lamp holder casing, and the rivet draw-in groove has still played the positioning action to the rivet in addition, makes rivet and lamp holder casing combine more firmly, has improved the rate of certified products.

Description

Lamp holder and lamp

Technical Field

The utility model belongs to the technical field of lamps and lanterns.

Background

Referring to fig. 1 to 3, the lamp cap includes a metal shell 2, an insulator 1 connected to a head of the metal shell, and a pin 3 connected to the insulator, the insulator is provided with a wire hole 11 for a wire to pass through, a first end of the wire hole communicates with a rivet hole, and the rivet hole is connected with a rivet. Since the rivet needs to press the lead wire passing through the wire passing hole, a gap is generated between the rivet and the lamp cap housing, which causes defects.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a lamp holder and lamps and lanterns are provided, produce the gap between rivet and lamp holder casing, and can automated production need the structure.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a lamp holder, includes metal casing, connects in the insulator of metal casing head and the pin of connecting the insulator, the insulator is equipped with the wire feed hole that supplies the wire to pass, the first end intercommunication rivet hole in wire feed hole, rivet hole connection rivet, the rivet hole is equipped with the rivet draw-in groove that holds the rivet head at a rivet head place port portion.

The utility model discloses a rivet draw-in groove, the rivet head can be impressed in the rivet draw-in groove when pushing down the wire, consequently can not form the gap between rivet and lamp holder casing, and can automated production need the structure. In addition, the rivet clamping groove has a positioning effect on the rivet, so that the rivet is combined with the lamp cap shell more firmly, and the rate of qualified products is improved.

Preferably, the rivet hole is provided with a reinforcing rib for enhancing structural strength.

Preferably, the pin is provided with one end and both ends protrude out of the insulator.

Preferably, the insulator is an injection molding body, and the pin and the insulator are integrated through injection molding.

Preferably, the second end of the threading hole is provided with a conical threading guide opening.

The utility model also provides a lamps and lanterns, including foretell lamp holder.

The specific technical solution and the advantages of the present invention will be described in detail in the following detailed description with reference to the accompanying drawings.

Detailed Description

In a first embodiment, referring to fig. 4 to 7, a lamp cap includes a metal shell 2, an insulator 1 connected to a head of the metal shell, and a pin 3 connected to the insulator, where the insulator 1 is provided with a wire passing hole 11 for a wire to pass through, a first end of the wire passing hole 11 is communicated with a rivet hole 113, the rivet hole 113 is connected to a rivet, and a rivet slot 114 for accommodating a rivet head is provided at a port portion where the rivet head is located in the rivet hole. Due to the design of the rivet clamping groove 114, the rivet can be pressed into the rivet clamping groove 114 when the lead is pressed, so that a gap cannot be formed between the rivet and the lamp cap shell, and the rivet clamping groove also plays a role in positioning the rivet, so that the rivet and the lamp cap shell are combined more firmly, and the rate of qualified products is improved.

In addition, the problem that the plastic part at the rivet installing position is not high enough in strength and is easy to break when the rivet is installed is solved. The rivet holes are provided with reinforcing ribs 115 that enhance structural strength. A circle of reinforcing rib is respectively designed on the inner surface and the outer surface of the rivet hole so as to ensure that the strength of a product is enough when rivets are arranged automatically.

Referring to fig. 2, the two pins 3 in the prior art are separated, so that the two separated pins are easy to loosen during manufacturing and bend. Thus, this embodiment uses a pin with two ends that extend out of the insulator 1.

In the present embodiment, the insulator 1 is made of injection molding, and the pin 3 is injection molded and integrated with the insulator 1. A pin of adoption integral type is directly moulded plastics and is installed on the lamp holder, can solve product pin not hard up and crooked problem. Of course, it will be understood by those skilled in the art that the insulator 1 may also be of a conventional glass-cast construction.

In addition, a second end of the threading hole 111 is provided with a conical threading guide port 112, which is convenient for threading of automation equipment.

It will be understood by those skilled in the art that the metal shell is made of aluminum or copper or iron, or other metal materials commonly used in the lamp base.

In a second embodiment, a lamp includes the lamp cap.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
